what kinds of complications related to COVID-19 are associated with hypertension?

Hypertension is one of the most common comorbidities in patients with coronavirus disease 2019 (COVID-19). This study aimed to clarify the impact of hypertension on COVID-19 and investigate whether the prior use of renin-angiotensin-aldosterone system (RAAS) inhibitors affects the prognosis of COVID-19. A total of 996 patients with COVID-19 were enrolled, including 282 patients with hypertension and 714 patients without hypertension. Propensity score-matched analysis (1:1 matching) was used to adjust the imbalanced baseline variables between the 2 groups. Patients with hypertension were further divided into the RAAS inhibitor group (n=41) and non-RAAS inhibitor group (n=241) according to their medication history. The results showed that COVID-19 patients with hypertension had more severe secondary infections, cardiac and renal dysfunction, and depletion of CD8+ cells on admission. Patients with hypertension were more likely to have comorbidities and complications and were more likely to be classified as critically ill than those without hypertension. Cox regression analysis revealed that hypertension (hazard ratio, 95% CI, unmatched cohort [1.80, 1.20-2.70]; matched cohort [2.24, 1.36-3.70]) was independently associated with all-cause mortality in patients with COVID-19. In addition, hypertensive patients with a history of RAAS inhibitor treatment had lower levels of C-reactive protein and higher levels of CD4+ cells. The mortality of patients in the RAAS inhibitor group (9.8% versus 26.1%) was significantly lower than that of patients in the non-RAAS inhibitor group. In conclusion, hypertension may be an independent risk factor for all-cause mortality in patients with COVID-19. Patients who previously used RAAS inhibitors may have a better prognosis.

Clinical Features of COVID-19 in Patients With Essential Hypertension and the Impacts of Renin-angiotensin-aldosterone System Inhibitors on the Prognosis of COVID-19 Patients.

Investigations reported that hypertension, diabetes, and cardiovascular diseases were the most prevalent comorbidities among the patients with coronavirus disease 2019 (COVID-19). Hypertension appeared consistently as the most prevalent risk factors in COVID-19 patients. Some investigations speculated about the association between renin-angiotensin-aldosterone system (RAAS) and susceptibility to COVID-19, as well as the relationship between RAAS inhibitors and increased mortality in these patients. This raised concern about the potential association between hypertension (and its treatment) and propensity for COVID-19. There are only a few follow-up studies that investigated the impact of comorbidities on outcome in these patients with conflicting findings. Hypertension has been proven to be more prevalent in patients with an adverse outcome (admission in intensive care unit, use of mechanical ventilation, or death). So far, there is no study that demonstrated independent predictive value of hypertension on mortality in COVID-19 patients. There are many speculations about this coronavirus and its relation with different risk factors and underlying diseases. The aim of this review was to summarize the current knowledge about the relationship between hypertension and COVID-19 and the role of hypertension on outcome in these patients.

COVID-19 and arterial hypertension: Hypothesis or evidence?

Considering the number of patients affected by SARS-CoV-2, the World Health Organization declared a pandemic on 11 March 2020. A number of publications regarding the course of COVID-19 infection and its relation to comorbidities have appeared since December 2019, when the first cases of atypical pneumonia were diagnosed in China. There is evidence of the higher susceptibility and higher risk of unfavourable outcomes in comorbid patients, including those with hypertension. We summarize the available data on the association with the COVID-19 infection and arterial hypertension, and discuss potential risks, e. g. the risks and benefits of antihypertensive therapy (in particular, related to the blockers of renin-angiotensin-aldosterone system) and the management approaches.

COVID-19: What are the risks in hypertensive patients?

INTRODUCTION As the coronavirus disease 2019 (COVID-19) outbreak, identification of clinical predictors of severe or fatal disease are necessary to enable risk stratification and optimize allocation of limited resources. Hypertension has been widely reported to be associated with increase disease severity, however, other studies have reported different findings. OBJECTIVES To evaluate the association of hypertension and severe and fatal COVID-19. PATIENTS AND METHODS Scopus, Medline, and Web of Science was performed to identify studies reporting the rate of hypertension in COVID-19 patients with severe or non-severe disease or among survivors and non-survivors. The obtained data was pooled into a meta-analysis to calculate odds ratio (OR) with 95% confidence intervals (95%CI). RESULTS Hypertension was associated with a nearly 2.5-fold significantly increased risk of severe COVID-19 disease (OR: 2.49 [95%CI: 1.98-3.12] I2=24%), as well as with a similarly significant higher risk of mortality (OR: 2.42 [95%CI: 1.51-3.90] I2=0%). In meta-regression, a significant correlation was observed with an increase in mean age of patients with severe COVID-19 associated with increased log odds of hypertension and severity (p=0.03). CONCLUSIONS The results of this pooled analysis of the current scientific literature would suggest that hypertension may be associated with an up to 2.5-fold higher risk of severe and fatal COVID-19, especially among older individuals.

Hypertension and its severity or mortality in Coronavirus Disease 2019 (COVID-19): a pooled analysis.

INTRODUCTION: As the outbreak of coronavirus disease 2019 (COVID19) was recognized, the clinical predictors of severe or fatal course of the disease should be identified to enable risk stratification and to allocate limited resources optimally. Hypertension has been widely reported to be associated with increased disease severity; however, some studies reported different findings. OBJECTIVES: The study aimed to evaluate the association between hypertension and severe and fatal COVID19. PATIENTS AND METHODS: The Scopus, Medline, and Web of Science databases were searched to identify studies reporting the rate of hypertensive patients in the population diagnosed with severe or nonsevere COVID19 or in COVID-19 survivors and nonsurvivors. The obtained data were pooled into a metaanalysis to calculate odds ratios (ORs) with 95% CIs. RESULTS: Hypertension was associated with a nearly 2.5fold increased risk of severe COVID19 (OR, 2.49; 95% CI, 1.98-3.12; I2 = 24%), as well as with a similarly significant higher mortality risk (OR, 2.42; 95% CI, 1.51-3.90; I2 = 0%). In a metaregression analysis, a correlation was observed between an increase in the mean age of patients with severe COVID19 and an increased log OR of hypertension and COVID-19 severity (P = 0.03). CONCLUSIONS: This pooled analysis of the current literature would suggest that hypertension may be associated with an up to 2.5fold higher risk of severe or fatal COVID19, especially in older individuals.

Hypertension in patients with coronavirus disease 2019 (COVID-19): a pooled analysis

Investigations reported that hypertension, diabetes, and cardiovascular diseases were the most prevalent comorbidities among the patients with coronavirus disease 2019 (COVID‐19). Hypertension appeared consistently as the most prevalent risk factors in COVID‐19 patients. Some investigations speculated about the association between renin‐angiotensin‐aldosterone system (RAAS) and susceptibility to COVID‐19, as well as the relationship between RAAS inhibitors and increased mortality in these patients. This raised concern about the potential association between hypertension (and its treatment) and propensity for COVID‐19. There are only a few follow‐up studies that investigated the impact of comorbidities on outcome in these patients with conflicting findings. Hypertension has been proven to be more prevalent in patients with an adverse outcome (admission in intensive care unit, use of mechanical ventilation, or death). So far, there is no study that demonstrated independent predictive value of hypertension on mortality in COVID‐19 patients.

The aim of this review was to summarize the current knowledge about the relationship between hypertension and COVID‐19 and the role of hypertension on outcome in these patients.

COVID‐19 and arterial hypertension: Hypothesis or evidence?

The coronavirus disease (COVID-19) has spread all around the world in a very short period of time. Recent data are showing significant prevalence of arterial hypertension and cardiovascular diseases (CVD) among patients with COVID-19, which raised many questions about higher susceptibility of patients with these comorbidities to the novel coronavirus, as well as the role of hypertension and CVD in progression and the prognosis of COVID-19 patients. There is a very limited amount of data, usually obtained from a small population, regarding the effect of the underlying disease on the outcome in patients with COVID-19. The evaluation of the treatment of these comorbidities at baseline and during COVID-19 is scarce and the results are conflicting. Hypertension and CVD, after the adjustment for other clinical and demographic parameters, primarily age, did not remain independent predictors of the lethal outcome in COVID-19 patients. Some investigations speculated about the association between the renin-angiotensin-aldosterone system (RAAS) and susceptibility to COVID-19, as well as the relationship between RAAS inhibitors and the adverse outcome in these patients. Withdrawing or switching RAAS inhibitors would have uncertain benefits, but it would definitely have many disadvantages such as uncontrolled hypertension, cardiac function deterioration and renal function impairment, which could potentially induce more complications in patients with COVID-19 than the infection of coronavirus itself. The aim of this review article was to summarize the prevalence of hypertension and CVD in patients with COVID-19, their influence on the outcome and the effect of treatment of hypertension and CVD in COVID-19 patients.

COVID-19, hypertension and cardiovascular diseases: Should we change the therapy?

This study aims to explore the effect of hypertension on disease progression and prognosis in patients with coronavirus disease 2019 (COVID-19). A total of 310 patients diagnosed with COVID-19 were studied. A comparison was made between two groups of patients, those with hypertension and those without hypertension. Their demographic data, clinical manifestations, laboratory indicators, and treatment methods were collected and analyzed. A total of 310 patients, including 113 patients with hypertension and 197 patients without hypertension, were included in the analysis. Compared with patients without hypertension, patients with hypertension were older, were more likely to have diabetes and cerebrovascular disease, and were more likely to be transferred to the intensive care unit. The neutrophil count and lactate dehydrogenase, fibrinogen, and D-dimer levels in hypertensive patients were significantly higher than those in nonhypertensive patients (P < 0.05). However, multivariate analysis (adjusted for age and sex) failed to show that hypertension was an independent risk factor for COVID-19 mortality or severity. COVID-19 patients with hypertension were more likely than patients without hypertension to have severe pneumonia, excessive inflammatory reactions, organ and tissue damage, and deterioration of the disease. Patients with hypertension should be given additional attention to prevent worsening of their condition.

COVID-19 patients with hypertension have more severe disease: a multicenter retrospective observational study

Hypertension is a common comorbidity in COVID-19 patients. However, the association of hypertension with the severity and fatality of COVID-19 remain unclear. In the present meta-analysis, relevant studies reported the impacts of hypertension on SARS-CoV-2 infection were identified by searching PubMed, Elsevier Science Direct, Web of Science, Wiley Online Library, Embase and CNKI up to 20 March 2020. As the results shown, 12 publications with 2389 COVID-19 patients (674 severe cases) were included for the analysis of disease severity. The severity rate of COVID-19 in hypertensive patients was much higher than in non-hypertensive cases (37.58% vs 19.73%, pooled OR: 2.27, 95% CI: 1.80-2.86). Moreover, the pooled ORs of COVID-19 severity for hypertension vs. non-hypertension was 2.21 (95% CI: 1.58-3.10) and 2.32 (95% CI: 1.70-3.17) in age <50 years and â©¾50 years patients, respectively. Additionally, six studies with 151 deaths of 2116 COVID-19 cases were included for the analysis of disease fatality. The results showed that hypertensive patients carried a nearly 3.48-fold higher risk of dying from COVID-19 (95% CI: 1.72-7.08). Meanwhile, the pooled ORs of COVID-19 fatality for hypertension vs. non-hypertension was 6.43 (95% CI: 3.40-12.17) and 2.66 (95% CI: 1.27-5.57) in age <50 years and â©¾50 years patients, respectively. Neither considerable heterogeneity nor publication bias was observed in the present analysis. Therefore, our present results provided further evidence that hypertension could significantly increase the risks of severity and fatality of SARS-CoV-2 infection.

Association of hypertension with the severity and fatality of SARS-CoV-2 infection: A meta-analysis

BACKGROUND: Previous studies have shown that Coronavirus Disease 2019 (COVID-19) patients with underlying comorbidities can have worse outcomes. However, the effect of hypertension on outcomes of COVID-19 patients remains unclear. RESEARCH QUESTION: The aim of this study was to explore the effect of hypertension on the outcomes of patients with COVID-19 by using propensity score–matching (PSM) analysis. STUDY DESIGN AND METHODS: Participants enrolled in this study were patients with COVID-19 who had been hospitalized at the Central Hospital of Wuhan, China. Chronic comorbidities and laboratory and radiological data were reviewed; patient outcomes and lengths of stay were obtained from discharge records. We used the Cox proportional-hazard model (CPHM) to analyze the effect of hypertension on these patients’ outcomes and PSM analysis to further validate the abovementioned effect. RESULTS: A total of 226 patients with COVID-19 were enrolled in this study, of whom 176 survived and 50 died. The proportion of patients with hypertension among non-survivors was higher than that among survivors (26.70% vs. 74.00%; P < 0.001). Results obtained via CPHM showed that hypertension could increase risk of mortality in COVID-19 patients (hazard ratio 3.317; 95% CI [1.709–6.440]; P < 0.001). Increased D-dimer levels and higher ratio of neutrophils to lymphocytes (N/L) were also found to increase these patients’ mortality risk. After matching on propensity score, we still came to similar conclusions. After we applied the same method in critically ill patients, we found that hypertension also increased risk of death in patients with severe COVID-19. CONCLUSION: Hypertension, increased D-dimer and the ratio of neutrophil to lymphocyte increased mortality in patients with COVID-19, with hypertension in particular.

Cardiovascular comorbidity and its impact on patients with Covid-19

OBJECTIVE: To investigate the association between hypertension and outcome in patients with Coronavirus Disease 2019 (COVID-19) pneumonia. METHODS: We performed a systematic literature search from several databases on studies that assess hypertension and outcome in COVID-19. Composite of poor outcome, comprising of mortality, severe COVID-19, acute respiratory distress syndrome (ARDS), need for intensive care unit (ICU) care and disease progression were the outcomes of interest. RESULTS: A total of 6560 patients were pooled from 30 studies. Hypertension was associated with increased composite poor outcome (risk ratio (RR) 2.11 (95% confidence interval (CI) 1.85, 2.40), p < 0.001; I2, 44%) and its sub-group, including mortality (RR 2.21 (1.74, 2.81), p < 0.001; I2, 66%), severe COVID-19 (RR 2.04 (1.69, 2.47), p < 0.001; I2 31%), ARDS (RR 1.64 (1.11, 2.43), p = 0.01; I2,0%, p = 0.35), ICU care (RR 2.11 (1.34, 3.33), p = 0.001; I2 18%, p = 0.30), and disease progression (RR 3.01 (1.51, 5.99), p = 0.002; I2 0%, p = 0.55). Meta-regression analysis showed that gender (p = 0.013) was a covariate that affects the association. The association was stronger in studies with a percentage of males < 55% compared to â©¾ 55% (RR 2.32 v. RR 1.79). CONCLUSION: Hypertension was associated with increased composite poor outcome, including mortality, severe COVID-19, ARDS, need for ICU care and disease progression in patients with COVID-19.

Meta-regression analysis showed that gender (p = 0.013) was a covariate that affects the association. The association was stronger in studies with a percentage of males < 55% compared to ⩾ 55% (RR 2.32 v. RR 1.79). CONCLUSION: Hypertension was associated with increased composite poor outcome, including mortality, severe COVID-19, ARDS, need for ICU care and disease progression in patients with COVID-19.

Objectives: It is unclear whether patients with hypertension are more likely to be infected with SARS-COV-2 than the general population and whether there is a difference in the severity of COVID-19 pneumonia in patients who have taken ACEI/ARB drugs to lower blood pressure compared to those who have not. Methods: This observational study included data from all patients with clinically confirmed COVID-19 who were admitted to the Hankou Hospital, Wuhan, China between January 5 and March 8, 2020. Data were extracted from clinical and laboratory records. Follow-up was cutoff on March 8, 2020. Results: A total of 274 patients, 75 with hypertension and 199 without hypertension, were included in the analysis. Patients with hypertension were older and were more likely to have pre-existing comorbidities, including chronic renal insufficiency, cardiovascular disease, diabetes mellitus, and cerebrovascular disease than patients without hypertension. Moreover, patients with hypertension tended to have higher positive COVID-19 PCR detection rates. Patients with hypertension who had previously taken ACEI/ARB drugs for antihypertensive treatment have an increased tendency to develop severe pneumonia after infection with SARS-COV-2 (P = 0.064). Conclusions: COVID-19 patients with hypertension were significantly older and were more likely to have underlying comorbidities, including chronic renal insufficiency, cardiovascular disease, diabetes mellitus, and cerebrovascular disease. Patients with hypertension who had taken ACEI/ARB drugs for antihypertensive treatment have an increased tendency to develop severe pneumonia after infection with SARS-COV-2. In future studies, a larger sample size and multi-center clinical data will be needed to support our conclusions.

Hypertension in patients hospitalized with COVID-19 in Wuhan, China: A single-center retrospective observational study

Hypertension is a common comorbidity in COVID-19 patients. However, the association of hypertension with the severity and fatality of COVID-19 remain unclear. In the present meta-analysis, relevant studies reported the impacts of hypertension on SARS-CoV-2 infection were identified by searching PubMed, Elsevier Science Direct, Web of Science, Wiley Online Library, Embase and CNKI up to 20 March 2020. As the results shown, 12 publications with 2389 COVID-19 patients (674 severe cases) were included for the analysis of disease severity. The severity rate of COVID-19 in hypertensive patients was much higher than in non-hypertensive cases (37.58% vs 19.73%, pooled OR: 2.27, 95% CI: 1.80–2.86). Moreover, the pooled ORs of COVID-19 severity for hypertension vs. non-hypertension was 2.21 (95% CI: 1.58–3.10) and 2.32 (95% CI: 1.70–3.17) in age <50 years and ⩾50 years patients, respectively. Additionally, six studies with 151 deaths of 2116 COVID-19 cases were included for the analysis of disease fatality. The results showed that hypertensive patients carried a nearly 3.48-fold higher risk of dying from COVID-19 (95% CI: 1.72–7.08). Meanwhile, the pooled ORs of COVID-19 fatality for hypertension vs. non-hypertension was 6.43 (95% CI: 3.40–12.17) and 2.66 (95% CI: 1.27–5.57) in age <50 years and ⩾50 years patients, respectively. Neither considerable heterogeneity nor publication bias was observed in the present analysis. Therefore, our present results provided further evidence that hypertension could significantly increase the risks of severity and fatality of SARS-CoV-2 infection.

There are several risk factors for worse outcomes in patients with coronavirus 2019 disease (COVID-19). Patients with hypertension appear to have a poor prognosis, but there is no direct evidence that hypertension increases the risk of new infection or adverse outcomes independent of age and other risk factors. There is also concern about use of renin-angiotensin system (RAS) inhibitors due to a key role of angiotensin-converting enzyme 2 receptors in the entry of the SARS-CoV-2 virus into cells. However, there is little evidence that use of RAS inhibitors increases the risk of SARS-CoV-2 virus infection or worsens the course of COVID-19. Therefore, antihypertensive therapy with these agents should be continued. In addition to acute respiratory distress syndrome, patients with severe COVID-19 can develop myocardial injury and cytokine storm, resulting in heart failure, arteriovenous thrombosis, and kidney injury. Troponin, N-terminal pro-B-type natriuretic peptide, D-dimer, and serum creatinine are biomarkers for these complications and can be used to monitor patients with COVID-19 and for risk stratification. Other factors that need to be incorporated into patient management strategies during the pandemic include regular exercise to maintain good health status and monitoring of psychological well-being. For the ongoing management of patients with hypertension, telemedicine-based home blood pressure monitoring strategies can facilitate maintenance of good blood pressure control while social distancing is maintained. Overall, multidisciplinary management of COVID-19 based on a rapidly growing body of evidence will help ensure the best possible outcomes for patients, including those with risk factors such as hypertension.

COVID-19 and hypertension-evidence and practical management: Guidance from the HOPE Asia Network

The virus responsible for COVID-19 binds to the angiotensin converting enzyme-2 (ACE-2) receptor [1]. Several articles have noted that hypertension is a risk factor for COVID-19 [2-7]. It is currently difficult to distinguish between hypertension as an independent risk factor in COVID-19 from one that co-varies with other patient factors such as age and cardiovascular disease. It is difficult from individual reports to determine whether hypertension is a risk factor for development of symptomatic disease or hospitalisation or for more severe disease. Reviewing the literature that reports rates of hypertension amongst included patients indicates a consistent association with more severe disease and increased mortality.

The importance of hypertension as a risk factor for severe illness and mortality in COVID‐19

The association between hypertension, diabetes, cardio and cerebrovascular disease and severe and fatal COVID-19, described in different countries, is remarkable. Myocardial damage and myocardial dysfunction are postulated as a possible causal nexus. Frequent findings of elevated troponin levels and electrocardiographic anomalies support this concept. On the other hand, hypotheses in favour and against a deleterious effect of angiotensin converting enzyme inhibitors and angiotensin receptor blockers, a usual treatment for cardiovascular disease, have been raised. There is currently no solid evidence and thus properly designed studies on this subject are urgently needed. In this context, patients with cardiovascular disease should especially avoid being exposed to the virus, should not self-medicate and rapidly seek medical advice should they show symptoms of infection.

PURPOSE OF REVIEW: There is increasing evidence indicating an association between several risk factors and worse prognosis in patients with coronavirus disease 2019 (COVID-19), including older age, hypertension, heart failure, diabetes, and pulmonary disease. Hypertension is of particular interest because it is common in adults and there are concerns related to the use of renin-angiotensin system (RAS) inhibitors in patients with hypertension infected with COVID-19. Levels of angiotensin-converting enzyme 2 (ACE2), a protein that facilitates entry of coronavirus into cells, may increase in patients using RAS inhibitors. Thus, chronic use of RAS inhibition could potentially lead to a more severe and fatal form of COVID-19. In this review, we provide a critical review to the following questions: (1) Does hypertension influence immunity or ACE2 expression favoring viral infections? (2) Are the risks of complications in hypertension mediated by its treatment? (3) Is aging a major factor associated with worse prognosis in patients with COVID-19 and hypertension? RECENT FINDINGS: Despite the potential involvement of immune responses in the pathogenesis of hypertension, there is no evidence supporting that hypothesis that hypertension or RAS inhibitors contributes to unfavorable outcomes in viral infections. Future investigations adopting a strict protocol for confirming hypertension status as well as assessing associated comorbidities that may influence outcomes are necessary. From the therapeutic perspective, recombinant ACE2 may serve as a potential therapy, but relevant studies in humans are lacking. Definitive evidence regarding the use of RAS inhibitors in patients with COVID-19 is needed; 5 randomized trials examining this issue are currently underway. SUMMARY: There is no current scientific support for claiming that hypertension or its treatment with RAS inhibitors contribute to unfavorable outcomes in COVID-19.

Is Hypertension a Real Risk Factor for Poor Prognosis in the COVID-19 Pandemic?

Systemic arterial hypertension (referred to as hypertension herein) is a major risk factor of mortality worldwide, and its importance is further emphasized in the context of the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection referred to as COVID-19. Patients with severe COVID-19 infections commonly are older and have a history of hypertension. Almost 75% of patients who have died in the pandemic in Italy had hypertension. This raised multiple questions regarding a more severe course of COVID-19 in relation to hypertension itself as well as its treatment with renin–angiotensin system (RAS) blockers, e.g. angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs). We provide a critical review on the relationship of hypertension, RAS, and risk of lung injury. We demonstrate lack of sound evidence that hypertension per se is an independent risk factor for COVID-19. Interestingly, ACEIs and ARBs may be associated with lower incidence and/or improved outcome in patients with lower respiratory tract infections. We also review in detail the molecular mechanisms linking the RAS to lung damage and the potential clinical impact of treatment with RAS blockers in patients with COVID-19 and a high cardiovascular and renal risk. This is related to the role of angiotensin-converting enzyme 2 (ACE2) for SARS-CoV-2 entry into cells, and expression of ACE2 in the lung, cardiovascular system, kidney, and other tissues. In summary, a critical review of available evidence does not support a deleterious effect of RAS blockers in COVID-19 infections. Therefore, there is currently no reason to discontinue RAS blockers in stable patients facing the COVID-19 pandemic.

COVID-19 and hypertension

The novel respiratory Syndrome Coronavirus-2 (SARS-CoV-2) caused a cluster of pneumonia cases in China at the end of 2019. After few months, it led to a pandemic that has spread throughout most countries of the world (https://coronavirus.jhu.edu/map.html).

Severity of COVID-19: The importance of being hypertensive.

Severity of COVID-19: The importance of being hypertensive

AIM: The novel coronavirus infection (COVID-19), now a worldwide public health concern is associated with varied fatality. Patients with chronic underlying conditions like diabetes and hypertension have shown worst outcomes. The understanding of the association might be helpful in early vigilant monitoring and better management of COVID-19 patients at high risk. The aim of the meta-analysis was to assess the association of diabetes and hypertension with severity of disease. METHODS: A literature search was conducted using the databases PubMed and Cochrane until March 31, 2020. Seven studies were included in the meta- analysis, including 2018 CIVID-19 patients. RESULTS: Diabetes was lower in the survivors (OR: 0.56; 95%CI: 0.35-0.90; p=0.017; I2: 0.0%) and non-severe (OR: 1.66; 95%CI: 1.20-2.30; p=0.002; I2: 0.0%) patients. No association of diabetes was found with ICU care. Hypertension was positively associated with death (OR: 0.49; 95%CI: 0.34-0.73; p=0.000; I2: 0.0%), ICU care (OR: 0.42; 95%CI: 0.22-0.81; p=0.009; I2: 0.0%) and severity (OR: 2.69; 95%CI: 1.27-5.73; p=0.01; I2: 52.4%). CONCLUSIONS: Our findings suggest that diabetes and hypertension have a negative effect on health status of COVID-19 patients. However, large prevalence studies demonstrating the consequences of comorbid diabetes and hypertension are urgently needed to understand the magnitude of these vexatious comorbidities.

Association of diabetes and hypertension with disease severity in covid-19 patients: a systematic literature review and exploratory meta-analysis

Abstract Aim The novel coronavirus infection (COVID-19), now a worldwide public health concern is associated with varied fatality. Patients with chronic underlying conditions like diabetes and hypertension have shown worst outcomes. The understanding of the association might be helpful in early vigilant monitoring and better management of COVID-19 patients at high risk. The aim of the meta-analysis was to assess the association of diabetes and hypertension with severity of disease. Methods A literature search was conducted using the databases PubMed and Cochrane until March 31, 2020. Seven studies were included in the meta- analysis, including 2018 CIVID-19 patients. Results Diabetes was lower in the survivors (OR: 0.56; 95%CI: 0.35-0.90; p=0.017; I2 : 0.0%) and non-severe (OR: 1.66; 95%CI: 1.20-2.30; p=0.002; I2 : 0.0%) patients. No association of diabetes was found with ICU care. Hypertension was positively associated with death (OR: 0.49; 95%CI: 0.34-0.73; p=0.000; I2 : 0.0%), ICU care (OR: 0.42; 95%CI: 0.22-0.81; p=0.009; I2 : 0.0%) and severity (OR: 2.69; 95%CI: 1.27-5.73; p=0.01; I2 : 52.4%). Conclusions Our findings suggest that diabetes and hypertension have a negative effect on health status of COVID-19 patients. However, large prevalence studies demonstrating the consequences of comorbid diabetes and hypertension are urgently needed to understand the magnitude of these vexatious comorbidities.

We have read with great interest the recently published study from Guan et al. [1] entitled Comorbidity and its impact on 1590 patients with Covid-19 in China: A Nationwide Analysis. To the best of our knowledge this is the first large scale study that focuses on independent clinical risk factors associated with a composite outcome (death, use of ventilator or ICU requirement), using a Cox regression model.

Arterial hypertension and the risk of severity and mortality of COVID-19

Background: COVID-19 patients with chronic diseases such as hypertension, diabetes and coronary heart diseases is more likely to worsen, but with mixed results for COVID-19 severity. This meta-analysis is to analyze the correlation between hypertension, diabetes, coronary heart disease and COVID-19 disease severity. Methods: Available data from PubMed, Web of Science, China National Knowledge Infrastructure Database, WanFang Database and VIP Database, were analyzed using a fixed effects model meta-analysis to derive overall odds ratios (OR) with 95% CIs. Funnel plots and Begg's were used to assess publication bias. Findings: Of 182 articles found following our initial search, we assessed 34 full-text articles, of which 9 articles with 1936 COVID-19 patients met all selection criteria for our meta-analysis. No significant heterogeneity between studies. There were significant correlations between COVID-19 severity and hypertension [OR=2.3 [95% CI (1.76, 3.00), P<0.01], diabetes [OR=2.67, 95% CI (1.91, 3.74), P<0.01], coronary heart disease [OR=2.85 [95% CI (1.68, 4.84), P<0.01]. Most of the studies in the funnel plot are on the upper part and few on the base part, and are roughly symmetrical left and right. Begg's test: hypertension (Z=-0.1, P=1.0), diabetes (Z=0.73, P=0.466), coronary heart disease (Z=0.38, P=0.707), all found no publication bias. Interpretation: Hypertension, diabetes, and coronary heart disease can affect the severity of COVID-19. It may be related to the imbalance of angiotensin-converting enzyme 2 (ACE2) and the cytokine storm induced by Glucolipid metabolic disorders (GLMD).

Hypertension and COVID-19

No adequate evidence indicating hypertension as an independent risk factor for COVID-19 severity

The importance of hypertension as a risk factor for severe illness and mortality in COVID-19

COVID 19, caused by the SARS-CoV-2 virus, a newly discovered coronavirus, has caused the global pandemic of early 2020. The first case was described in December 2019 in Wuhan, China, and by March 2020, most countries around the world have put in place some of the strictest restrictions seen in decades in order to slow down the spread of the disease. Patients with pre-existing hypertension and cardiovascular comorbidities were reported to be at an increased risk of serious infections caused by SARS-CoV-2. Considering that those are among the most common chronic medical conditions in the Western world, the potential impact of it is huge. The proposed mechanism behind those associations is the expression of angiotensin converting enzyme II (ACE II) in those patients. Furthermore, the association between ACE inhibitors/AR blockers, which are among the most frequently prescribed medications, and serious cases of COVID 19 has been studied with the same mechanism in mind. The reports on the association between hypertension and COVID 19 morbidity and mortality are less clear, and the International Society of Hypertension even claims that there is none. The reports on the association between heart failure or coronary disease and COVID 19 are more uniform, and all seem to point to a greater risk from serious infections faced by patients with those comorbidities. A significant effort will need to be invested by the scientific community into finding strategies for protecting those patients from contracting the virus in the first place and then, once infected, into developing management plans aimed at preserving cardiac function as much as possible.

SARS-CoV-2 (COVID 19) Infection in Hypertensive Patients and in Patients With Cardiac Disease

Systemic arterial hypertension (referred to as hypertension herein) is a major risk factor of mortality worldwide, and its importance is further emphasized in the context of the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection referred to as COVID-19. Patients with severe COVID-19 infections commonly are older and have a history of hypertension. Almost 75% of patients who have died in the pandemic in Italy had hypertension. This raised multiple questions regarding a more severe course of COVID-19 in relation to hypertension itself as well as its treatment with renin-angiotensin system (RAS) blockers, e.g. angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs). We provide a critical review on the relationship of hypertension, RAS, and risk of lung injury. We demonstrate lack of sound evidence that hypertension per se is an independent risk factor for COVID-19. Interestingly, ACEIs and ARBs may be associated with lower incidence and/or improved outcome in patients with lower respiratory tract infections. We also review in detail the molecular mechanisms linking the RAS to lung damage and the potential clinical impact of treatment with RAS blockers in patients with COVID-19 and a high cardiovascular and renal risk. This is related to the role of angiotensin-converting enzyme 2 (ACE2) for SARS-CoV-2 entry into cells, and expression of ACE2 in the lung, cardiovascular system, kidney, and other tissues. In summary, a critical review of available evidence does not support a deleterious effect of RAS blockers in COVID-19 infections. Therefore, there is currently no reason to discontinue RAS blockers in stable patients facing the COVID-19 pandemic.

Hypertension, the renin-angiotensin system, and the risk of lower respiratory tract infections and lung injury: implications for COVID-19

BACKGROUND AND AIMS: To undertake a review and critical appraisal of published/preprint reports that offer methods of determining the effects of hypertension, diabetes, stroke, cancer, kidney issues, and high-cholesterol on COVID-19 disease severity. METHODS: A search was conducted by two authors independently on the freely available COVID-19 Open Research Dataset (CORD-19). We developed an automated search engine to screen a total of 59,000 articles in a few seconds. Filtering of the articles was then undertaken using keywords and questions, e.g. “Effects of diabetes on COVID/normal coronavirus/SARS-CoV-2/nCoV/COVID-19 disease severity, mortality?“. The search terms were repeated for all the comorbidities considered in this paper. Additional articles were retrieved by searching via Google Scholar and PubMed. FINDINGS: A total of 54 articles were considered for a full review. It was observed that diabetes, hypertension, and cholesterol levels possess an apparent relation to COVID-19 severity. Other comorbidities, such as cancer, kidney disease, and stroke, must be further evaluated to determine a strong relationship to the virus. CONCLUSION: Reports associating cancer, kidney disease, and stroke with COVID-19 should be carefully interpreted, not only because of the size of the samples, but also because patients could be old, have a history of smoking, or have any other clinical condition suggesting that these factors might be associated with the poor COVID-19 outcomes rather than the comorbidity itself. Further research regarding this relationship and its clinical management is warranted.

Association of hypertension, diabetes, stroke, cancer, kidney disease, and high-cholesterol with COVID-19 disease severity and fatality: A systematic review

ABSTRACT Hypertension emerged from early reports as a potential risk factor for worse outcomes for persons with coronavirus disease 2019 (COVID-19). Among the putative links between hypertension and COVID-19 is a key counter-regulatory component of the renin-angiotensin system (RAS): angiotensin-converting enzyme 2 (ACE2). ACE2 facilitates entry of SARS-CoV-2, the virus responsible for COVID-19, into host cells. Since RAS inhibitors have been suggested to increase ACE2 expression, healthcare providers and patients have grappled with the decision of whether to discontinue these medications during the COVID-19 pandemic. However, experimental models of analogous viral pneumonias suggest RAS inhibitors may exert protective effects against acute lung injury. We review how RAS and ACE2 biology may affect outcomes in COVID-19 through pulmonary and other systemic effects. In addition, we briefly detail the data for and against continuation of RAS inhibitors in persons with COVID-19 and summarize the current consensus recommendations from select specialty organizations.

COVID-19 and Hypertension: The Role of ACE2 and the Renin-Angiotensin System

There are several risk factors for worse outcomes in patients with coronavirus 2019 disease (COVID‐19). Patients with hypertension appear to have a poor prognosis, but there is no direct evidence that hypertension increases the risk of new infection or adverse outcomes independent of age and other risk factors. There is also concern about use of renin‐angiotensin system (RAS) inhibitors due to a key role of angiotensin‐converting enzyme 2 receptors in the entry of the SARS‐CoV‐2 virus into cells. However, there is little evidence that use of RAS inhibitors increases the risk of SARS‐CoV‐2 virus infection or worsens the course of COVID‐19. Therefore, antihypertensive therapy with these agents should be continued. In addition to acute respiratory distress syndrome, patients with severe COVID‐19 can develop myocardial injury and cytokine storm, resulting in heart failure, arteriovenous thrombosis, and kidney injury. Troponin, N‐terminal pro‐B‐type natriuretic peptide, D‐dimer, and serum creatinine are biomarkers for these complications and can be used to monitor patients with COVID‐19 and for risk stratification. Other factors that need to be incorporated into patient management strategies during the pandemic include regular exercise to maintain good health status and monitoring of psychological well‐being. For the ongoing management of patients with hypertension, telemedicine‐based home blood pressure monitoring strategies can facilitate maintenance of good blood pressure control while social distancing is maintained. Overall, multidisciplinary management of COVID‐19 based on a rapidly growing body of evidence will help ensure the best possible outcomes for patients, including those with risk factors such as hypertension.

COVID‐19 and hypertension—evidence and practical management: Guidance from the HOPE Asia Network

Coronavirus disease 2019 (COVID-19) has caused a devastating global pandemic and continues to overwhelm the health-care facilities and shatter the economies of countries worldwide. Although it primarily affects the lungs, it shares a strong interplay with the cardiovascular system. The presence of underlying cardiovascular disease and its risk factors (diabetes, hypertension) predispose the patients to increased severity and mortality associated with COVID-19. On the other hand, COVID-19 itself leads to various cardiovascular complications, which increase its associated morbidity and mortality in affected patients. It is, therefore, prudent to review the rapidly evolving data in this field and understand the mechanisms behind the cardiovascular involvement of this lethal disease.

Cardiovascular comorbidities and complications associated with coronavirus disease 2019

Abstract Background and aims COVID-19 is already a pandemic. Emerging data suggest an increased association and a heightened mortality in patients of COVID-19 with comorbidities. We aimed to evaluate the outcome in hypertensive patients with COVID-19 and its relation to the use of renin-angiotensin system blockers (RASB). Methods We have systematically searched the medical database up to March 27, 2020 and retrieved all the published articles in English language related to our topic using MeSH key words. Results From the pooled data of all ten available Chinese studies (n = 2209) that have reported the characteristics of comorbidities in patients with COVID-19, hypertension was present in nearly 21%, followed by diabetes in nearly 11%, and established cardiovascular disease (CVD) in approximately 7% of patients. Although the emerging data hints to an increase in mortality in COVID-19 patients with known hypertension, diabetes and CVD, it should be noted that it was not adjusted for multiple confounding factors. Harm or benefit in COVID-19 patients receiving RASB has not been typically assessed in these studies yet, although mechanistically and plausibly both, benefit and harm is possible with these agents, given that COVID-19 expresses to tissues through the receptor of angiotensin converting enzyme-2. Conclusion Special attention is definitely required in patients with COVID-19 with associated comorbidities including hypertension, diabetes and established CVD. Although the role of RASB has a mechanistic equipoise, patients with COVID-19 should not stop these drugs at this point of time, as recommended by various world organizations and without the advice of health care provider.

Comorbidities in COVID-19: Outcomes in hypertensive cohort and controversies with renin angiotensin system blockers

AIMS: It remains unknown whether the treatment of hypertension influences the mortality of patients diagnosed with coronavirus disease 2019 (COVID-19). METHODS AND RESULTS: This is a retrospective observational study of all patients admitted with COVID-19 to Huo Shen Shan Hospital. The hospital was dedicated solely to the treatment of COVID-19 in Wuhan, China. Hypertension and the treatments were stratified according to the medical history or medications administrated prior to the infection. Among 2877 hospitalized patients, 29.5% (850/2877) had a history of hypertension. After adjustment for confounders, patients with hypertension had a two-fold increase in the relative risk of mortality as compared with patients without hypertension [4.0% vs. 1.1%, adjusted hazard ratio (HR) 2.12, 95% confidence interval (CI) 1.17-3.82, P = 0.013]. Patients with a history of hypertension but without antihypertensive treatment (n = 140) were associated with a significantly higher risk of mortality compared with those with antihypertensive treatments (n = 730) (7.9% vs. 3.2%, adjusted HR 2.17, 95% CI 1.03-4.57, P = 0.041). The mortality rates were similar between the renin-angiotensin-aldosterone system (RAAS) inhibitor (4/183) and non-RAAS inhibitor (19/527) cohorts (2.2% vs. 3.6%, adjusted HR 0.85, 95% CI 0.28-2.58, P = 0.774). However, in a study-level meta-analysis of four studies, the result showed that patients with RAAS inhibitor use tend to have a lower risk of mortality (relative risk 0.65, 95% CI 0.45-0.94, P = 0.20). CONCLUSION: While hypertension and the discontinuation of antihypertensive treatment are suspected to be related to increased risk of mortality, in this retrospective observational analysis, we did not detect any harm of RAAS inhibitors in patients infected with COVID-19. However, the results should be considered as exploratory and interpreted cautiously.

Association of hypertension and antihypertensive treatment with COVID-19 mortality: a retrospective observational study

In December 2019, COVID-19 outbroke in Wuhan, China. The current study aimed to explore the clinical characteristics of COVID-19 complicated by hypertension. In this retrospective, single-center study, we recruited 110 discharged patients with COVID-19 at Wuhan Fourth Hospital in Wuhan, China, from January 25 to February 20, 2020. All study cases were grouped according to whether they had a history of hypertension. Then, a subgroup analysis for all hypertensive patients was carried out based on whether to take ACEI or ARB drugs. The mean age of 110 patients was 57.7 years (range, 25–86 years), of which 60 (54.5%) were male patients. The main underlying diseases included hypertension [36 (32.7%)] and diabetes [11 (10.0%)]. Compared with the non-hypertensive group, the lymphocyte count was significantly lower in the hypertensive group (average value, 0.96 × 10(9)/L vs 1.26 × 10(9)/L), and analysis of clinical outcomes showed that the crude mortality rate was higher in the hypertensive group [7/36 (19.4%) vs 2/74 (2.7%)]. Patients treated with ACEI or ARB, compared with the control group, were younger (average age, 58.5 years vs 69.2 years), but there was no statistical difference in the crude cure rate [10/15 (66.7%) vs 15/21 (71.4%)] and the crude mortality rate [2/15 (13.3%) vs 5/21 (23.8%)]. In conclusions, the COVID-19 patients with a history of hypertension had a significantly lower lymphocyte count on admission. The elderly and comorbidities such as hypertension may together constitute risk factors for poor prognosis in patients with COVID-19. Taking ACEI or ARB drugs may not change the prognosis of COVID-19 patients with hypertension.

Arterial hypertension is the most common comorbid disease in patients who died as a result of SARS-Cov-2 infection. Numerous observational studies indicate a relationship between arterial hypertension and its treatment and SARS-Cov-2 coronavirus infection. It is known from experimental studies that SARS-Cov-2 enters the cells by interacting with the ACE2 enzyme, while it is not known whether ACE2 is the only factor that allows the virus to enter the cell. There is no clear evidence of a link between the use of medications such as ACE and ARB and an increased risk of SARS-Cov-2 infection. It has been shown that the use of recombinant ACE2 can be potentially beneficial in COVID-19 therapy by limiting the entry of the virus into the cell. Blood glucose as well as lipid profile should be monitored during SARS-Cov-2 coronavirus infection. This article attempts to gather key information on arterial hypertension and COVID-19.

COVID-19 patients with hypertension have more severity condition, and ACEI/ARB treatment have no infulence on the clinical severity and outcome

COVID-19 is a novel viral disease caused by SARS-CoV-2. The mid- and long-term outcomes have not yet been determined. COVID-19 infection is increasingly being associated with systemic and multi-organ involvement, encompassing cytokine release syndrome and thromboembolic, vascular and cardiac events. The patient described experienced unusually rapid development of pulmonary hypertension (PH) and right ventricular failure after recent severe COVID-19 pneumonia with cytokine release syndrome, which initially was successfully treated with methylprednisolone and tocilizumab. The development of pulmonary hypertension and right ventricular failure – in the absence of emboli on multiple CT angiograms – was most likely caused by progressive pulmonary parenchymal abnormalities combined with microvascular damage of the pulmonary arteries (group III and IV pulmonary hypertension, respectively). To the best of our knowledge, these complications have not previously been described and therefore awareness of PH as a complication of COVID-19 is warranted. LEARNING POINTS: COVID-19 increasingly presents with systemic and multi-organ involvement with vascular, thromboembolic and cardiac events. Patients with severe COVID-19 pneumonia and concomitant cytokine release syndrome may be particularly at risk for the development of secondary pulmonary hypertension and right ventricular failure. Pulmonary hypertension can develop unusually rapidly following COVID-19 pneumonia and probably results from progressive pulmonary interstitial and microvascular abnormalities due to COVID-19.

Are COVID-19 patients with hypertension at higher risk in China?

This article reports the diagnosis and treatment of two children with coronavirus disease 2019 (COVID-19) and hypertension. Case 1 was a boy aged 13 years and 3 months, with the main manifestations of fever and dry cough; chest CT showed ground-glass opacities, and the nucleic acid test of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) yielded a positive result. Case 2 was a boy aged 13 years and 8 months and had no clinical symptoms; chest CT showed no abnormality, while the nucleic acid test of SARS-CoV-2 yielded a positive result. Both cases were shown with family aggregation of SARS-CoV-2 infection. They had obesity and a family history of hypertension. Continuous blood pressure monitoring in the resting state during hospitalization showed that blood pressure was above the 95% reference interval of normal value for children of the same age, and the two boys were given calcium channel blockers or β-receptor blockers and were then recovered. It is concluded that comprehensive management of children with COVID-19 and underlying cardiovascular diseases, including hypertension, should be taken seriously during the epidemic.

Letter in response to the article: Comorbidities in COVID-19: Outcomes in hypertensive cohort and controversies with renin angiotensin system blockers (Singh et al.)

BACKGROUND: The coronavirus disease of 2019 (COVID-19) is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). While systemic inflammation and pulmonary complications can result in significant morbidity and mortality, cardiovascular complications may also occur. OBJECTIVE: This brief report evaluates cardiovascular complications in the setting of COVID-19 infection. DISCUSSION: The current COVID-19 pandemic has resulted in over one million infected worldwide and thousands of death. The virus binds and enters through angiotensin-converting enzyme 2 (ACE2). COVID-19 can result in systemic inflammation, multiorgan dysfunction, and critical illness. The cardiovascular system is also affected, with complications including myocardial injury, myocarditis, acute myocardial infarction, heart failure, dysrhythmias, and venous thromboembolic events. Current therapies for COVID-19 may interact with cardiovascular medications. CONCLUSIONS: Emergency clinicians should be aware of these cardiovascular complications when evaluating and managing the patient with COVID-19.

Importance. Exploring the association of coronavirus-2019 disease (COVID-19) mortality with chronic pre-existing conditions may promote the importance of targeting these populations during this pandemic in order to optimize survival. Objective. To explore the association of pre-existing conditions with COVID-19 mortality. Data Sources. MEDLINE, the OVID databases, SCOPUS, and Cochrane Register of Controlled Trials were searched for the period October 1, 2019 to May 1, 2020. Snowballing was used to identify additional studies. Study Selection. Observational studies (n=19) reporting on 61,455 patients with relative risks (RR) or hazard ratios or odds ratios that reported the risk of mortality in patients with COVID-19 and comorbid conditions were included for the current study. Data Extraction and Synthesis. Two independent reviewers extracted data and assessed the risk of bias. All analyses were performed using random-effects models and heterogeneity was quantified. Main Outcomes and Measures The outcome of interest was the risk of COVID-19 mortality in patients with and without pre-existing conditions, reported as RR. Comorbidities explored were cardiovascular diseases (coronary artery disease, hypertension, cardiac arrhythmias, and congestive heart failure), chronic obstructive pulmonary disease, type 2 diabetes, cancer, chronic kidney disease, chronic liver disease, and stroke. Results. Ten chronic conditions from 19 studies were included in the meta-analysis (n=61,455 patients with COVID-19; mean age, 61 years; 57% male). Any cardiovascular disease, coronary heart disease, hypertension, congestive heart failure, and cancer significantly increased the risk of mortality from COVID-19. Cardiovascular disease was associated with a 135% higher risk of COVID-19 mortality (RR=2.35, 95%CI 1.44-3.84 n=9). The risk of mortality from COVID-19 in patients with coronary heart disease was 2.4 times as high as those without coronary heart disease (RR= 2.40, 95%CI=1.71-3.37, n=5) and twice as high in patients with hypertension as high as that compared to those without hypertension (RR=1.89, 95%CI= 1.58-2.27, n=9). Patients with cancer also were at twice the risk of mortality from COVID-19 compared to those without cancer (RR=1.93 95%CI 1.15-3.24, n=4), and those with congestive heart failure were at 2.5 times the risk of mortality compared to those without congestive heart failure (RR=2.66, 95%CI 1.58-4.48, n=3). Conclusions and Relevance COVID-19 patients with all any cardiovascular disease, coronary heart disease, hypertension, congestive heart failure, and cancer have an increased risk of mortality. Tailored infection prevention and treatment strategies targeting this high-risk population are warranted to optimize survival.

The association of cardiovascular disease and other pre-existing comorbidities with COVID-19 mortality: A systematic review and meta-analysis

OBJECTIVE: To explore the association between obesity, type 2 diabetes, hypertension, and severe COVID-19 on admission. METHODS: In the present study, a total of 23,593 patient samples were evaluated by a laboratory from the Mexican Institute of Epidemiological Diagnosis and Reference (InDRE, for its acronym in Spanish). Of these: 18,443 were negative for COVID-19, 3,844 were positive for COVID-19, and 1,306 were positive for other respiratory viruses. Severe types of respiratory disease were defined by the presence of pneumonia and other organ failure that requires intensive care. Multivariable logistic regression models were used to explore factors associated with severe COVID-19 on admission. RESULTS: Patients who tested positive for COVID-19 had a higher proportion of obesity (17.4%), diabetes (14.5%), and hypertension (18.9%), compared to those without a confirmed diagnosis. Compared to non-obese patients, those with obesity showed a 1.43-fold higher odds of developing severe COVID-19 on admission, while subjects with diabetes and hypertension showed a 1.87-fold and 1.77-fold higher odds of developing severe COVID-19 on admission, respectively. CONCLUSION: Obesity, diabetes, and hypertension were significantly associated with severe COVID-19 on admission and the association of obesity was stronger in patients < 50 y.

The association between obesity, type 2 diabetes, and hypertension with severe COVID-19 on admission among Mexicans

The prevalence of hypertension is high in patients affected by coronavirus disease 2019 (COVID-2019) and it appears to be related to an increased risk of mortality, as shown in many epidemiological studies. The angiotensin-converting enzyme (ACE) system is not uniformly expressed in all of the human races, and current differences could explain some of the geographical discrepancies in infection around the world. Furthermore, animal studies have shown that the ACE2 receptor is a potential pathway for host infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of COVID-19. As two-thirds of hypertensive patients take ACE inhibitors/angiotensin receptor blockers, several concerns have been raised about the detrimental role of current antihypertensive drugs in COVID-19. This report summarizes the recent evidence for and against the administration of ACE blockade in the COVID-19 era.

Hypertension prevalence in human coronavirus disease: the role of ACE system in infection spread and severity

Abstract Background The coronavirus disease of 2019 (COVID-19) is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). While systemic inflammation and pulmonary complications can result in significant morbidity and mortality, cardiovascular complications may also occur. Objective This brief report evaluates cardiovascular complications in the setting of COVID-19 infection. Discussion The current COVID-19 pandemic has resulted in over one million infected worldwide and thousands of death. The virus binds and enters through angiotensin-converting enzyme 2 (ACE2). COVID-19 can result in systemic inflammation, multiorgan dysfunction, and critical illness. The cardiovascular system is also affected, with complications including myocardial injury, myocarditis, acute myocardial infarction, heart failure, dysrhythmias, and venous thromboembolic events. Current therapies for COVID-19 may interact with cardiovascular medications. Conclusions Emergency clinicians should be aware of these cardiovascular complications when evaluating and managing the patient with COVID-19.

Abstract A new coronavirus, called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was discovered in December 2019 in Wuhan, China; the virus escalated rapidly and on March 11, 2020, the World Health Organization declared it a pandemic.Emerging data suggests that older patients with COVID-19 associated with other comorbid conditions such as diabetes, hypertension, heart and lung diseases are particularly more susceptible, compared to general populations, and have higher mortality. It is not yet clear whether this increased association of high blood pressure with COVID-19 and the increased risk of mortality are directly related to high blood pressure or other associated comorbidities, or to antihypertensive treatment.Although the underlying pathogenic mechanism linking hypertension and severity of COVID-19 infection remains to be elucidated, it has been hypothesized that excessive activation of the renin-angiotensin system (RAS) could contribute to the progression of COVID-19 related lung injury.Concern about whether angiotensin II receptor blockers (ARBs) and angiotensin converting enzyme (ACE) inhibitors may have deleterious effects on morbidity and mortality in patients with COVID-19 is based on speculation that these drugs would increase the regulation of angiotensin II converting enzyme (ACE2), a receptor for SARS-CoV-2, which would increase viral load and lung damage.Recent studies are consistent with the recommendations of scientific societies that propose avoiding the suspension or change of antihypertensive medication, as there is no evidence that shows that these can be taken as risk factors for severity or mortality from COVID-19.

Abstract Aims To analyze the potential mechanism of cardiovascular dysfunctions induced by Coronavirus Disease 2019 (COVID-19) and to evaluate more effective therapeutic pathways for patients with cardiovascular diseases. Data Synthesis COVID-19 mainly invades the lungs, causing its serious damage. Studies found that COVID-19 induced the renin-angiotensin system imbalance, inflammatory storm, hypoxemia and stress response et al, all contributed to hypertension and serious myocardial damage in the process of virus pathogenesis, even increasing mortality in COVID-19 patients. Conclusions In the process of management of COVID-19 infections, close attention should be paid on both lung and cardiovascular damage, especially on those with only symptoms of cardiovascular diseases. Early identification, timely and effective treatments, maintenance of hemodynamics and electrophysiological stability are of great significance on effective treatment and long-term prognosis. The pandemic of COVID-19 has been taking lives worldwide. It caused by a novel coronavirus which human being are lack of defensive function in whole population. It targets human’s lung and causes serious damage of lungs. Based on early reports, for people with underlying heart issues, the concerns are serious. It appears people over 65 with coronary heart diseases or hypertension is more likely to be infected and to develop more severe symptoms. In addition, some of hospitalized COVID-19 patients had cardiovascular diseases in China. As characteristic analysis of COVID-19 patients, hypertension and severe myocardial damage contribute to severity [1] and mortality of COVID-19 patients [2]. Therefore, to better understand the development of COVID-19 and the impacts of cardiovascular diseases will add valuable measures to the management of COVID-19 patients.

A close-up on COVID-19 and cardiovascular diseases

BACKGROUND: Cardiovascular disease related mortality is the leading cause of death in the United States, with hypertension being the most prevalent and potent risk factor. For decades hypertension has disproportionately affected African Americans, who also have a higher burden of associated comorbidities including diabetes and heart failure. METHODS: Current literature including guideline reports and newer studies on hypertension in African Americans in PubMed were reviewed. We also reviewed newer publications on the relationship between COVID-19 and cardiovascular disease. FINDINGS: While APOL1 has been theorized in the epidemiology of hypertension, the increased prevalence and associated risks are primarily due to environmental and lifestyle factors. These factors include poor diet, adverse lifestyle, and social determinants. Hypertension control can be achieved by lifestyle modifications such as low sodium diet, weight loss, and adequate physical activity. When lifestyle modifications alone do not adequately control hypertension, a common occurrence among African Americans who suffer with greater prevalence of resistant hypertension, pharmacological intervention is indicated. The efficacy of renal denervation, and the use of sodium-glucose cotransporter 2 and aminopeptidase A inhibitors, have been studied for treatment of resistant hypertension. Furthermore, the recent COVID-19 crisis has been particularly devastating among African Americans who demonstrate increased incidence and poorer health outcomes related to the disease. CONCLUSION: The disparities in outcomes, which are largely attributable to a greater prevalence of comorbidities such as hypertension and obesity, in addition to adverse environmental and socioeconomic factors, highlight the necessity of specialized clinical approaches and programs for African Americans to address longstanding barriers to equitable care.

Hypertension and coronavirus disease 2019 mortality

Arterial hypertension and the risk of severity and mortality of COVID-19

Since its recognition in December 2019, covid-19 has rapidly spread globally causing a pandemic. Pre-existing comorbidities such as hypertension, diabetes, and cardiovascular disease are associated with a greater severity and higher fatality rate of covid-19. Furthermore, covid-19 contributes to cardiovascular complications, including acute myocardial injury as a result of acute coronary syndrome, myocarditis, stress-cardiomyopathy, arrhythmias, cardiogenic shock, and cardiac arrest. The cardiovascular interactions of covid-19 have similarities to that of severe acute respiratory syndrome, Middle East respiratory syndrome and influenza. Specific cardiovascular considerations are also necessary in supportive treatment with anticoagulation, the continued use of renin-angiotensin-aldosterone system inhibitors, arrhythmia monitoring, immunosuppression or modulation, and mechanical circulatory support.

Cardiovascular manifestations and treatment considerations in covid-19

Arterial hypertension is the most common comorbid disease in patients who died as a result of SARS-Cov-2 infection Numerous observational studies indicate a relationship between arterial hypertension and its treatment and SARS-Cov-2 coronavirus infection It is known from experimental studies that SARS-Cov-2 enters the cells by interacting with the ACE2 enzyme, while it is not known whether ACE2 is the only factor that allows the virus to enter the cell There is no clear evidence of a link between the use of medications such as ACE and ARB and an increased risk of SARS-Cov-2 infection It has been shown that the use of recombinant ACE2 can be potentially beneficial in COVID-19 therapy by limiting the entry of the virus into the cell Blood glucose as well as lipid profile should be monitored during SARS-Cov-2 coronavirus infection This article attempts to gather key information on arterial hypertension and COVID-19

Reply to the Letter of Mahajan and Gaur in response to the article: Comorbidities in COVID-19: outcomes in hypertensive cohort and controversies with renin angiotensin system blockers (Singh et al.)

INTRODUCTION: There is controversy concerning the use of angiotensin-converting enzyme inhibitors (ACEI) or angiotensin II type-I receptor blockers (ARB) for treating hypertensive patients with Covid-19. It has been hypothesized that these drugs might increase the risk of severe Covid-19, but some authors suggested that blocking the renin-angiotensin system might actually decrease this risk. METHODS: Retrospective cohort study of all the consecutive hypertensive patients with confirmed SARS-CoV-2 infection in a health area. The outcome variable was hospitalization because of severe Covid-19. RESULTS: 539 subjects were diagnosed of SARS-CoV-2 infection. Of these, 157 (29.1%) had hypertension and were included in the study. Sixty-nine cases (43.9%) were hospitalized because of severe Covid-19. In multivariable analysis older age, diabetes and hypertensive myocadiopathy were related to a higher risk of hospital admission. ARB treatment was associated with a significantly lower risk of hospitalization (HR: 0.29, 95% CI: 0.10 - 0.88). A similar albeit not significant trend was observed for ACEI. CONCLUSION: ARB or ACEI treatment was not associated with a worse clinical outcome in consecutive hypertensive patients infected by SARS-CoV-2.

Risk of severe COVID-19 in hypertensive patients treated with renin-angiotensin-aldosterone system inhibitors

Angiotensin converting enzyme 2 (ACE2) is the cellular entry point for severe acute respiratory syndrome coronavirus (SARS-CoV-2) - the cause of COVID-19 disease. It has been hypothesized that use of renin-angiotensin system (RAS) inhibiting medications in patients with hypertension, increases the expression of ACE2 and thereby increases the risk of COVID-19 infection and severe outcomes or death. However, the effect of RAS-inhibition on ACE2 expression in human tissues of key relevance to blood pressure regulation and COVID-19 infection has not previously been reported. We examined how hypertension, its major metabolic co-phenotypes and antihypertensive medications relate to ACE2 renal expression using information from up to 436 patients whose kidney transcriptomes were characterised by RNA-sequencing. We further validated some of the key observations in other human tissues and/or a controlled experimental model. Our data reveal increasing expression of ACE2 with age in both human lungs and the kidney. We show no association between renal expression of ACE2 and either hypertension or common types of RAS inhibiting drugs. We demonstrate that renal abundance of ACE2 is positively associated with a biochemical index of kidney function and show a strong enrichment for genes responsible for kidney health and disease in ACE2 co-expression analysis. Collectively, our data indicate that neither hypertension nor antihypertensive treatment are likely to alter individual risk of SARS-CoV-2 infection or influence clinical outcomes in COVID-19 through changes of ACE2 expression. Our data further suggest that in the absence of SARS-CoV-2 infection, kidney ACE2 is most likely nephro-protective but the age-related increase in its expression within lungs and kidneys may be relevant to the risk of SARS-CoV-2 infection.

Hypertension and renin-angiotensin system blockers are not associated with expression of Angiotensin Converting Enzyme 2 (ACE2) in the kidney

Mortality from coronavirus disease 2019 (COVID-19) is strongly associated with cardiovascular disease, diabetes, and hypertension. These disorders share underlying pathophysiology related to the renin-angiotensin system (RAS) that may be clinically insightful. In particular, activity of the angiotensin-converting enzyme 2 (ACE2) is dysregulated in cardiovascular disease, and this enzyme is used by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to initiate the infection. Cardiovascular disease and pharmacologic RAS inhibition both increase ACE2 levels, which may increase the virulence of SARS-CoV-2 within the lung and heart. Conversely, mechanistic evidence from related coronaviruses suggests that SARS-CoV-2 infection may downregulate ACE2, leading to toxic overaccumulation of Angiotensin II that induces acute respiratory distress syndrome and fulminant myocarditis. RAS inhibition could mitigate this effect. With conflicting mechanistic evidence, we propose key clinical research priorities necessary to clarify the role of RAS inhibition in COVID-19 mortality that could be rapidly addressed by the international research community.

Is There an Association Between COVID-19 Mortality and the Renin-Angiotensin System—a Call for Epidemiologic Investigations

COVID-19, hypertension and angiotensin receptor-blocking drugs

A Significance of High Prevalence of Diabetes and Hypertension in Severe COVID-19 Patients

Introduction: COVID-19 disproportionately affects those with comorbidities and the elderly. Hypertension is the most common pre-existing condition amongst COVID-19 patients. Upregulation of the renin-angiotensin-aldosterone system (RAAS) is common in hypertensive patients and may promote inflammation and ensuing cytokine storm in COVID-19. It is unknown whether RAAS inhibition with ACE1 inhibitors or angiotensin-receptor blockers (ARB) can be harmful or beneficial. Methods: Within Hackensack Meridian Health network, the largest healthcare provider in New Jersey, we performed a retrospective, multicenter, convenience sampling study of hospitalized COVID-19 patients. Demographics, clinical characteristics, treatments, and outcomes were manually abstracted. Fishers exact tests, and logistic regression were performed. Results: Among 3017 hospitalized COVID-19 patients, 1584 (52.5%) carried a diagnosis of hypertension. In the discharged or deceased cohort, the overall mortality was significantly increased at 35% vs 13% among COVID-19 patients with hypertension. However, when adjusted for age, the effect of hypertension on mortality was greatly diminished, with a reduction in odds-ratio by over half; and completely disappeared when adjusted for other major covariates. The mortality rates were lower for hypertensive patients prescribed ACE1 (27%, p=0.001) or ARBs (33%, p=0.12) compared to other anti-hypertensive agents (39%) in the unadjusted analyses. RAAS inhibitor therapy appeared protective compared to other anti-hypertensive agents (p=0.001). Conclusions: While our results are limited by the retrospective nature of our study and by potential confounders, our data argue against a harmful effect of RAAS inhibition and support the HFSA/AHA/ACC joint statement recommending continuing ACE1 and ARB therapy in hypertensive COVID-19 patients.

Patients with arterial hypertension and COVID-19 are at higher risk of ICU admission

OBJECTIVE: To explore the association between obesity, type 2 diabetes, hypertension, and severe COVID‐19 on admission. METHODS: In the present study, a total of 23,593 patient samples were evaluated by a laboratory from the Mexican Institute of Epidemiological Diagnosis and Reference (InDRE, for its acronym in Spanish). Of these: 18,443 were negative for COVID‐19, 3,844 were positive for COVID‐19, and 1,306 were positive for other respiratory viruses. Severe types of respiratory disease were defined by the presence of pneumonia and other organ failure that requires intensive care. Multivariable logistic regression models were used to explore factors associated with severe COVID‐19 on admission. RESULTS: Patients who tested positive for COVID‐19 had a higher proportion of obesity (17.4%), diabetes (14.5%), and hypertension (18.9%), compared to those without a confirmed diagnosis. Compared to non‐obese patients, those with obesity showed a 1.43‐fold higher odds of developing severe COVID‐19 on admission, while subjects with diabetes and hypertension showed a 1.87‐fold and 1.77‐fold higher odds of developing severe COVID‐19 on admission, respectively. CONCLUSION: Obesity, diabetes, and hypertension were significantly associated with severe COVID‐19 on admission and the association of obesity was stronger in patients < 50 y.

Several factors have been proposed to explain the high death rate of the coronavirus disease 2019 (COVID-19) outbreak, including hypertension and hypertension-related treatment with Renin Angiotensin System inhibitors. Also, age and multimorbidity might be confounders. No sufficient data are available to demonstrate their independent role. We designed a cross-sectional, observational, multicenter, nationwide survey in Italy to verify whether renin-angiotensin system inhibitors are related to COVID-19 severe outcomes. We analyzed information from Italian patients diagnosed with COVID-19, admitted in 26 hospitals. One thousand five hundred ninety-one charts (male, 64.1%; 66±0.4 years) were recorded. At least 1 preexisting condition was observed in 73.4% of patients, with hypertension being the most represented (54.9%). One hundred eighty-eight deaths were recorded (11.8%; mean age, 79.6±0.9 years). In nonsurvivors, older age, hypertension, diabetes mellitus, chronic obstructive pulmonary disease, chronic kidney disease, coronary artery diseases, and heart failure were more represented than in survivors. The Charlson Comorbidity Index was significantly higher in nonsurvivors compared with survivors (4.3±0.15 versus 2.6±0.05; P<0.001). ACE (angiotensin-converting enzyme) inhibitors, diuretics, and β-blockers were more frequently used in nonsurvivors than in survivors. After correction by multivariate analysis, only age (P=0.0001), diabetes mellitus (P=0.004), chronic obstructive pulmonary disease (P=0.011), and chronic kidney disease (P=0.004) but not hypertension predicted mortality. Charlson Comorbidity Index, which cumulates age and comorbidities, predicts mortality with an exponential increase in the odds ratio by each point of score. In the COVID-19 outbreak, mortality is predicted by age and the presence of comorbidities. Our data do not support a significant interference of hypertension and antihypertensive therapy on COVID-19 lethality.

The current COVID-19 pandemic is associated with unprecedented morbidity and mortality. Early reports suggested an association between disease severity and hypertension but did not account for sources of confounding. However, the responsible virus — SARS-CoV-2 — gains entry to host cells via angiotensin-converting enzyme 2 (ACE2), highlighting the need to understand the relationship between the virus and the renin–angiotensin system (RAS) and how this might be affected by RAS inhibitors.

Angiotensin-Converting Enzyme 2 and Antihypertensives (Angiotensin Receptor Blockers and Angiotensin-Converting Enzyme Inhibitors) in Coronavirus Disease 2019

INTRODUCTION COVID-19, is a new corona virus of the Beta Coronavirus genus which originated in bats. The virus first emerged in China in December 2019 and has rapidly spread since to other areas worldwide. The World Health Organization (WHO) has therefore recently declared it as the source of a pandemic. The disease caused by the virus manifests in most cases as a lower respiratory tract infection leading to fever, cough and dyspnea, while more severe cases can led to respiratory failure and/or multi organ failure. COVID-19 enters the human cell using the ACE2, an enzyme abundant in renal tubular epithelial cells. Theoretically, this may be significant in several ways: acute kidney injury (AKI) as well as proteinuria and/or microhematuria could be associated with the penetration of COVID-19 into the cells. Moreover, medications based on RAAS inhibition, such and ACE inhibitors and ARBs, upregulate the enzyme ACE2 and could therefore hypothetically explain the high prevalence of hypertension and diabetes reported as previous diagnoses in severe cases. In the setting of chronic kidney disease, the risk of infection with COVID-19 is not clear at this time. However, hemodialysis patients represent a unique group of patients, mostly elderly and immunocompromised, for whom dialysis is a life-saving treatment which cannot be stopped. Hence, the COVID-19 pandemic has presented a complex medical and logistic challenge for the medical staff in hospital and community based dialysis units.

[COVID-19, THE KIDNEY AND HYPERTENSION].

Abstract Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2, is being defined as the worst pandemic disease of modern times. Several professional health organizations have published position papers stating that there is no evidence to change the use of angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) in the management of elevated blood pressure in the context of avoiding or treating COVID-19 infection. In this article, we review the evidence on the relationship between the renin-angiotensin-aldosterone system and COVID-19 infection. In agreement with current guidelines, patients with hypertension should continue taking antihypertensive medications as prescribed without interruption. Because ACEIs and ARBs are also used to retard the progression of chronic kidney disease, we suggest that these recommendations also apply to the use of these agents in chronic kidney disease. No differences generally exist between ARBs and ACEIs in terms of efficacy in decreasing blood pressure and improving other outcomes, such as all-cause mortality, cardiovascular mortality, myocardial infarction, heart failure, stroke, and end-stage renal disease. The ACEIs are associated with cough secondary to accumulation of bradykinin and angioedema, and withdrawal rates due to adverse events are lower with ARBs. Given their equal efficacy but fewer adverse events, ARBs could potentially be a more favorable treatment option in patients with COVID-19 at higher risk for severe forms of disease.

[covid-19, the Kidney and Hypertension]

The coronavirus disease-2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2. The link between cardiovascular disease and COVID-19 appears to be twofold. First, some reports of data indicate that certain groups of patients are more at risk of COVID-19. This includes patients with cardiovascular risk factors or pre-existing cardiovascular conditions and older patients. In addition, these patients incur disproportionately worse outcome. Second, SARS-CoV2 infection can be complicated by life-threatening cardiovascular acute diseases. Despite the rapid evolution of data on this pandemic, this review aims to highlight the cardiovascular considerations related to COVID-19 whether as comorbidities including concerns and uncertainty regarding the effect of renin-angiotensin-aldosterone system (RAAS) inhibitors on angiotensin conversion enzyme 2 or related to acute cardiovascular complications.

Pathologies cardiovasculaires et Covid-19 : particularités chez les personnes âgées./ COVID-19 and cardiovascular diseases: viewpoint for older patients

Background: Coronavirus disease 2019 (COVID-19), caused by a novel coronavirus (designated as SARS-CoV-2) has become a pandemic worldwide. Based on the current reports, hypertension may be associated with increased risk of sever condition in hospitalized COVID-19 patients. Angiotensin-converting enzyme 2 (ACE2) was recently identified to functional receptor of SARS-CoV-2. Previous experimental data revealed ACE2 level was increased following treatment with ACE inhibitors (ACEIs) and angiotensin receptor blockers (ARBs). Currently doctors concern whether these commonly used renin-angiotensin system (RAS) blockers-ACEIs/ARBs may increase the severity of COVID-19. Methods: We extracted data regarding 50 hospitalized hypertension patients with laboratory confirmed COVID-19 in the Renmin Hospital of Wuhan University from Feb 7 to Mar 03, 2020. These patients were grouped into RAS blockers group (Group A, n=20) and non-RAS blockers group (Group B, n=30) according to the basic blood pressure medications. All patients continued to use pre-admission antihypertensive drugs. Clinical severity (symptoms, laboratory and chest CT findings, etc.), clinical course, and short time outcome were analyzed after hospital admission. Results: Ten (50%) and seventeen (56.7%) of the Group A and Group B participants were males (P=0.643), and the average age was 52.65±13.12 and 67.77±12.84 years (P=0.000), respectively. The blood pressure of both groups was under effective control. There was no significant difference in clinical severity, clinical course and in-hospital mortality between Group A and Group B. Serum cardiac troponin I (cTnI) (P=0.03), and N-terminal (NT)-pro hormone BNP (NT-proBNP) (P=0.04) showed significant lower level in Group A than in Group B. But the patients with more than 0.04ng/mL or elevated NT-proBNP level had no statistical significance between the two groups. In patients over 65 years or under 65 years, cTnI or NT-proBNP level showed no difference between the two groups. Conclusions: We observed there was no obvious difference in clinical characteristics between RAS blockers and non-RAS blockers groups. These data suggest ACEIs/ARBs may have few effects on increasing the clinical severe conditions of COVID-19.

The effect of RAS blockers on the clinical characteristics of COVID-19 patients with hypertension

We report the case of a young patient diagnosed with coronavirus disease 2019 with a history of hypertension. The patient improved after antiviral treatment but eventually developed severe respiratory distress syndrome and cardiac insufficiency. His respiratory secretions were tested for nucleic acids and turn negative twice. Computed tomography image of the patient showed evidence of viral pneumonia on the 11(th) day of onset and continued to worsen. The patient was finally intubated and transferred to a higher-level care center for further treatment. We were very focused on infectious disease protection throughout the treatment, however, suboptimal treatment was provided due to the switch in antihypertensive medication, lack of early nutritional support, and fluid restriction management.

Are patients with hypertension and diabetes mellitus at increased risk for COVID-19 infection?

Based on some publications that associate SARS-CoV-2 infection with the use of anti-hypertensive drug groups such as angiotensin-converting-enzyme inhibitors (e.g. enalapril) or angiotensin II receptor blockers (e.g. losartan), many patients from South America, Central America or Spain, have stopped or intend to interrupt their treatments with these drugs. Hence, it may exist ominous consequences due to this drop out. For this reason, it is necessary to quickly warn about this situation and the risks associated with it.

Facts and reflections on COVID-19 and anti-hypertensives drugs

The COVID-19 pandemic, caused by SARS-CoV-2, is an immense challenge for global healthcare. Diabetes mellitus, hypertension and obesity have been shown to portend poor prognosis in COVID-19 despite no greater susceptibility to the infection (1). Chronic hypertension is commonly associated with vasculopathy which can predispose to severe infection. In patients with diabetes, severity is attributable to impaired innate, adaptive immunity, upregulation of ACE2 (entry receptor for SARS-CoV2) by acute hyperglycemia and diabetic vasculopathy. The background of chronic low grade inflammation characterised by increased levels of IL-6 and CRP in diabetes and obesity can also lead to an enhanced 'cytokine storm' in COVID-19 (2). ACE2 expression on endothelial cells has been reported to cause viral mediated endothelitis and precipitate vascular dysfunction manifesting as acute respiratory distress syndrome as well as myocarditis, heart failure, arrhythmias, myocardial infarction and renal failure (3). In patients with pre-existing comorbidities like hypertension, diabetes, obesity and chronic kidney disease, this new-onset organ dysfunction can have deleterious additive effects.

SGLT2 inhibition and COVID-19: The road not taken.

Importance: Data are lacking whether patients with hypertension who are taking angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) have increased severity or risk of mortality during hospitalization for coronavirus disease 2019 (COVID-19). Objective: To investigate the association between ACEIs/ARBs and severity of illness and mortality in patients with hypertension hospitalized for COVID-19 infection. Design, Setting, and Participants: Retrospective, single-center case series of the 1178 hospitalized patients with COVID-19 infections at the Central Hospital of Wuhan, China, from January 15 to March 15, 2020. Main Outcomes and Measures: COVID-19 was confirmed by real-time reverse transcription-polymerase chain reaction and epidemiologic, clinical, radiologic, laboratory, and drug therapy data were analyzed in all patients. The percentage of patients with hypertension taking ACEIs/ARBs was compared between those with severe vs nonsevere illness and between survivors vs nonsurvivors. Results: Of the 1178 patients with COVID-19, the median age was 55.5 years (interquartile range, 38-67 years) and 545 (46.3%) were men. The overall in-hospital mortality was 11.0%. There were 362 patients with hypertension (30.7% of the total group; median age, 66.0 years [interquartile range, 59-73 years]; 189 [52.2%] were men), of whom 115 (31.8%) were taking ACEI/ARBs. The in-hospital mortality in the patients with hypertension was 21.3%. The percentage of patients with hypertension taking ACEIs/ARBs did not differ between those with severe and nonsevere infections (32.9% vs 30.7%; P = .65) nor did it differ between nonsurvivors and survivors (27.3% vs 33.0%; P = .34). Similar findings were observed when data were analyzed for patients taking ACEIs and those taking ARBs. Conclusions and Relevance: This study provides clinical data on the association between ACEIs/ARBs and outcomes in patients with hypertension hospitalized with COVID-19 infections, suggesting that ACEIs/ARBs are not associated with the severity or mortality of COVID-19 in such patients. These data support current guidelines and societal recommendations for treating hypertension during the COVID-19 pandemic.
