Abstract

Background
The Baevsky Stress Index (BSTRi), calculated from Heart Rate Variability (HRV) data, has been proposed for quantitative assessment of physiological stress, with higher scores indicating higher levels of physical and/or psychological stress [1]. Cardiac autonomic modulation can be synthetically quantified by calculating the parasympathetic (PNSi) and the sympathetic (SNSi) indexes. The values of the BSTRi, SNSi, and PNSi in patients with synucleinopathies of different prognoses have not been reported yet.

Purpose
To quantify, in patients with Parkinson's disease (PD) and Multisystem Atrophy (MSA), the BSTRi, its correlation with the PNSi and the SNSi indexes, and their potential value for a synthetic assessment of cardiac autonomic modulation and early differential diagnosis between PD and MSA.

Methods
Holter ECG data of 66 patients with Parkinsonian syndromes were retrospectively analyzed after 10 years of follow-up. Out of them, 34 patients with a certain diagnosis of PD (17) and MSA (17) were selected for this study. HRV was analyzed with the Kubios software (version 4.0), providing automatic calculation of the BSTRi, PNSi, and SNSi [2], as well as of time domain (TD), frequency domain (FD), nonlinear (NL), and time-varying (TV) HRV parameters. HRV was calculated from selected short-term intervals (of 5 minutes), during daily activity (ACT5’), and non-REM sleep (NREM5’), and from 24-hours Holter recordings. Patients’ HRV findings were compared with those of 51 age-matched healthy subjects (HS).

Results
An example of individual automatic graphic summary is shown in Figure 1. Both short-term and 24-hour BSTRi and SNSi values were significantly (p &lt; 0.05) higher in PD and MSA compared to those of HS, in all investigated conditions. Short-term PNSi was significantly higher in HS than in PD in all conditions, but only during NREM5’ in MSA patients (Table 1). No significant difference was found between the indexes of PD and MSA patients. As in HS (R=92), BSTRi was positively correlated with the SNSi in MSA (average R= 0.83 and 0.89 during ACT5’ and NREM5’, respectively), but less evident in PD (R=0.67). The inverse correlation between PNSi and SNSi (R=0.75 in HS) was lost in both MSA and PD.

Conclusions
Higher values of BSTRi in PD and MSA compared to HS suggest that patients with synucleinopathies do experience higher levels of psychophysiological stress, which may affect their quality of life negatively. However, since no significant difference was found in this study between BSTRi values of PD and MSA patients, BSTRi seems at present unreliable for early differentiation between the two diseases. Telematic assessment of BSTRi, SNSi, and PNSi could be useful for remote monitoring of PD and MSA patients’ psychophysiological stress, to provide timely intervention and adaptive treatment.Fig.1 Example of graphic summary (ACT5')

Abstract

Background
Atrial fibrillation (AF) is the most prevalent atrial tachyarrhythmia, affecting an estimated 2-4% of adults worldwide. AF is a well-recognized and treatable risk factor for stroke, but it often remains asymptomatic or subclinical, leading to underdiagnosis. This study aimed to identify distinguishing signs during exercise stress echocardiography (ESE) among patients in sinus rhythm (SR), with and without history of paroxysmal/persistent AF (PAF).

Methods
An international prospective cohort comprising 1035 consecutive patients was initially considered from 12 cardiology institutions. These patients were referred for clinically-driven ESE as part of the Stress Echo 2020-2030 study network. All patients underwent comprehensive ESE with the ABCDE protocol, which included assessment of B-lines, left ventricle contractile reserve (LVCR), ECG-based heart rate reserve (HRR), LV ejection fraction (EF), LV end-diastolic volume, E/e’, pulmonary artery systolic pressure estimation, tricuspid annular plane sytolic excursion (TAPSE), left atrium volume index (LAVi) and left atrium reservoir phase strain (LASr) at rest and with exercise.

Results
After excluding 89 patients who were in AF during the ESE, 946 patients in SR were included as the main study cohort (101 with and 845 without a history of PAF). A scoring system was then constructed using all independent variables that differentiate the two groups (those with and without history of PAF). Presence of systemic hypertension, rest LAVI&gt;31ml/m2, rest |LASr|&lt; 21%, stress LAVI &gt;29 ml/m2, stress |LASr| &lt;24%, stress E/e’ &gt;7, ∆TAPSE &lt;4.5 mm, HRR&lt;1.87, and LVCR&lt;1.6 were identified as the discriminators between patients with and without PAF. The composite score, summing all 9 items (with a total score range from 0 to 9), yielded a score of &gt;4 as the best balance between sensitivity (87%) and specificity (60%) in predicting those with PAF. The receiver operating characteristic curve analysis of the scoring model showed an AUC of 0.79 (p-value &lt;0.0001), Figure.

Conclusion
ESE evaluation can be a valuable adjunct for identifying patients in SR with history of PAF. This multifaceted approach enhances the potential for more accurate detection and clinical management of individuals in SR at risk for AF, who could be considered for aggressive monitoring programs to prevent the development of new onset AF and subsequent increase in cardiovascular risk.

Abstract

Background
Early cardiovascular complications may occur in 20-30% of patients following following ischaemic stroke (stroke-heart-syndrome, SHS). The risk of dementia in patients with SHS remains unexplored. We aimed to quantify the risk of incident dementia in patients with SHS.

Methods
We conducted a retrospective analysis using a global federated health care network (TriNetX). We included patients who were discharged alive post-ischaemic stroke from 2000 to 2022. These individuals were classified into two cohorts based on the incidence of cardiovascular complications within 30 days post-stroke (acute heart failure [HF], acute myocardial infarction [AMI], ventricular fibrillation or flutter [VFF], or Takotsubo disease [TTS]), ie. those with SHS (Group 1) and those with stroke-only (without SHS; Group 2). The primary outcome was the five-year risk of dementia (vascular dementia [F01], dementia in other disease [F02], unspecified dementia [F03], Alzheimer’s disease [G30]). Hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using Cox regression analysis after 1:1 propensity score matching (PSM).

Results
We identified 70,113 patients with SHS (age 67.3±14.0; 42.2% females) and 1,092,540 patients with stroke-only (age 65.2±14.9, 48.1% females). Prior to PSM, patients with SHS were generally older and had a higher prevalence of cardiovascular treatments compared to those without SHS. Following PSM, 70,111 well-balanced patients were considered in each group, however, patients with SHS had a higher risk of dementia compared to patients with stroke-only (HR 1.25, 95%CI 1.20-1.30).
Among the SHS complications, the highest dementia risks were associated with acute HF (HR 1.28, 95%CI 1.21-1.36) and AMI (HR 1.24, 95%CI 1.17-1.30), with no significant associations were found for TTS, and VFF. The increased risk of dementia in patients with SHS compared to patients with stroke-only was independent of oral anticoagulant (OAC) use, sex, and age (&gt; or &lt; 75 years) [Figure 1].

Conclusion
Stroke-heart syndrome is associated with increased risk of dementia. Innovative strategies to identify and to prevent SHS complications would improve long-term prognosis in patients with recent stroke.

Published: October 2024

Abstract

Background/Introduction
Cardiovascular disease (CVD) remains a leading cause of global mortality, with percutaneous coronary intervention (PCI) being a common therapeutic procedure for managing CVD. While depression is recognized as a risk factor for adverse cardiovascular outcomes post-PCI, its association with stroke risk in this patient group has been less explored.

Purpose
This study aims to evaluate the association between pre-existing depression and the incidence of stroke, alongside other cardiovascular outcomes and mortality, in patients undergoing PCI.

Methods
Utilizing the Korean National Health Insurance Service database, a population-based retrospective cohort study was conducted, encompassing individuals who underwent PCI between 2010 and 2017, with a follow-up until 2019. Depression was identified through ICD-10 codes prior to PCI. The primary outcome was acute stroke incidence, with all-cause mortality and revascularization as secondary outcomes. Adjustments were made for sociodemographic, lifestyle factors, and comorbidities.

Results
Among 164,198 individuals, those with pre-existing depression (17.4% of the cohort) exhibited a 27% increased risk of acute stroke (aHR 1.27, 95% CI 1.20-1.35) and a 25% higher risk of all-cause mortality (aHR 1.25, 95% CI 1.21-1.29) compared to those without. The association was stronger in individuals under 65 years and varied by sex, with males showing a higher risk of mortality.

Conclusion(s)
Pre-existing depression in patients undergoing PCI is associated with a significantly increased risk of stroke and all-cause mortality, particularly in younger patients. These findings highlight the importance of depression management as part of comprehensive care in post-PCI patients, suggesting potential benefits in reducing stroke risk and improving survival outcomes. Further research is warranted to explore the mechanisms and intervention strategies that could mitigate these risks.Study FlowchartRisk of stroke and all-cause death

Abstract

Background
Brugada syndrome (BrS) is an inherited disorder with autosomal dominant transmission, which occurs predominantly in males in the third to fourth decade of life with resting syncope, nocturnal agonic breathing, major ventricular arrhythmias and sudden death. Arrhythmic complications can occur spontaneously or following exposure to triggers such as fever, or certain categories of medications, including psychiatric drugs.

Aim of the study
To evaluate the prevalence of Brugada ECG pattern in psychiatric patients.

Methods
from January 2023 to Decembre 2023, 550 consecutive patients who were admitted to the psychiatric department of our university hospital were enrolled. For each patient, electrocardiographic and anamnestic data including psychiatric diagnosis, current drug therapy and family history were collected.

Results
Twenty-one out of five-hundred and fifty patients (3.8%) presented with a Brugada ECG pattern. Mean age was 42±6 years and seventeen out of twenty-one patients (81%) were male.
Two patients exhibited a Spontaneous type 1 Brugada ECG pattern meanwhile nineteen patients had a Brugada type 2 or 3 ECG pattern. When compared to the general population, those with Brugada ECG had longer P wave duration (110±7 vs 103±13 msec p&lt;0.01) and longer QRS duration (97±14 vs 89±12 msec p=0.04).
Evaluating psychiatric disorders, patients with Brugada ECG had high prevalence of mood disorders (10 out of 21, 47%). Other disorders were schizophrenia (3 out of 21, 14%), cognitive retardation (5 out of 21, 23%), and attention disorder (1 out of 21, 5%). Moreover 4 patients were drug addicted. Only 5 out of 21 (24%) patients had a family history of psychiatric and neurological disorders.

Conclusions
Brugada ECG pattern has a prevalence of 3.8% in a large cohort of psychiatric patients. Mood disorders was the most common diagnosis in this cohort. Large prospective registries are needed to evaluate the clinical feature and potential clinical implication of this findings.

Abstract

Objectives
To validate the prognostic accuracy of anti-apolipoprotein A-1 IgG (AAA1) for incident major adverse cardiovascular (CV) events (MACE) in rheumatoid arthritis (RA) and study their associations with the lipid paradox at a multicentric scale.

Methods
Baseline AAA1 -, lipid profile, atherogenic indexes, and cardiac biomarkers were measured on the serum of 1472 RA patients included in the prospective Swiss Clinical Quality Management registry with a median follow-up duration of 4.4 years. MACE was the primary endpoint defined as CV death, incident fatal or nonfatal stroke, or myocardial infarction (MI), while elective coronary revascularisation (ECR) was the secondary endpoint. Discriminant accuracy, and incidence rate ratios (IRR) were respectively assessed by C-statistics and Poisson regression models.

Results
During follow-up, 2.4% (35/1472) patients experienced MACE, consisting in 6 CV deaths, 11 MI and 18 strokes. ECR occurred in 2.1% (31/1472) of patients. C-statistics indicated that AAA1 had a significant discriminant accuracy for incident MACE (C-statistics: 0.60, 95% confidence intervals [95%CI]: 0.57-0.98, p=0.03), mostly driven by CV deaths (C-statistics:0.77; 95%CI: 0.57-0.98, p=0.01) and without predicting incident ECR. IRR indicated that for every unit increase in AAA1, incident CV death rate increased by 5-fold (95%CI:3.6-7.3), independently of various models’ adjustments. At the predefined and validated cut-off, AAA1 displayed negative predictive values above 97% for the MACE components. AAA1 inversely correlated with total, and HDL cholesterol, but not with atherogenic indexes.

Conclusions
AAA1 independently predict CV deaths in RA. Whether AAA1 could improve CV risk stratification by identifying in particular low CV risk patients remains to be demonstrated.

Abstract

Background
Cystic fibrosis (CF) is an autosomal recessive disease affecting multiple organs, however the extent of cardiac involvement in CF is yet to be determined. The remarkable therapeutic advancements with new highly effective CF transmembrane conductance regulator (CFTR) modulator treatment and subsequent increase in life expectancy substantiates further research.

Purpose
We aimed to explore the prevalence of abnormalities and potential subclinical alterations in cardiac structure and function in adults with CF compared to matched controls and investigate potential cardiovascular risk factors in people with CF (pwCF).

Methods
In this cross-sectional study, 104 adult pwCF in Denmark underwent clinical and echocardiographic examination. All participants were matched 1:1 with controls from the general population on age and sex. Uni- and multivariable linear regression models with adjustment for heart rate, FEV1, smoking status, hypertension and CF-related diabetes (CFRD) were used to test for differences in echocardiographic parameters between cases and controls. Abnormal cardiac function was defined as left ventricular ejection fraction (LVEF) &lt;50%, left ventricular (LV) global longitudinal strain (GLS) &lt; 16% or presence of diastolic dysfunction. Uni- and multivariable logistic regression models adjusted for age, sex, homozygous genotype, FEV1/FVC, BMI, smoking status, CFRD, pancreatic insufficiency, hypertension, and ischemic heart disease were performed to assess associations between potential risk factors and cardiac dysfunction in CF. Forest plots were constructed to visually represent the findings.

Results
Of 104 pwCF, 44% were female, mean age was 34 years, 93% received CFTR modulator treatment, and 91% had mutations with only minimal CFTR function (mutation class I-III). The prevalence of abnormal cardiac function in pwCF was 44% versus 22% in controls. Compared to controls, pwCF were found to have smaller LV dimensions, worse LV diastolic function, and more impaired right ventricle (RV) as well as LV systolic function (Table). After multivariable adjustment, LV diastolic function as well as LV and RV systolic function remained impaired in pwCF as compared to controls. Male sex and decreasing FEV1/FVC ratio remained independently associated with abnormal cardiac function in pwCF (male sex: OR 3.94 (1.56; 9.95), p=0.004 and FEV1/FVC ratio: OR 2.05 per 0.1 unit decrease (1.21; 3.52), p=0.008, respectively) (Figure).

Conclusion
Both left- and right-sided cardiac alterations were found in pwCF. After adjustments for potential risk factors, both RV and LV systolic measures remained altered in pwCF, compared to controls. Male sex and decreasing pulmonary function evaluated by FEV1/FVC-ratio were identified as factors associated with abnormal cardiac function in pwCF.Figure

Abstract

Background/Introduction
Hidradenitis suppurativa (HS) is a chronic, recurrent, debilitating, inflammatory skin disease manifested by painful, deep-seated, inflamed lesions of the apocrine gland-bearing areas of the body (axillae, submammary folds, inguinal and anogenital region). HS has been associated, among others, with an increased cardiovascular risk.

Purpose
We aimed to investigate the endothelial, arterial and left ventricular (LV) myocardial function in patients with severe HS.

Methods
Twenty-eight, not previously treated patients (mean age: 36 ± 13 years) with Hurley stage III disease and a mean score of 19±8 on the International Hidradenitis Suppurativa Severity Score System (IHS4) scale, were studied. Twenty healthy sex-, age- and body mass index -matched individuals, who were also weighted for common cardiovascular risk factors, served as the control group. Both patients and controls were evaluated for: a) perfused boundary region (PBR) of the sublingual microvessels with a diameter of 5-25 μm (an increased PBR value is considered as an indicator of a decrease in thickness of the endothelial glycocalyx), using a dedicated camera (Microscan, GlycoCheck), b) carotid-femoral pulse wave velocity (PWV-Complior), c) flow-mediated dilation (FMD) of the brachial artery and d) LV global longitudinal strain (GLS) using the speckle-tracking echocardiography.

Results
Compared to healthy controls, HS patients had increased PBR value (2.32 ± 0.19 vs. 1.99 ± 0.14 μm, p &lt; 0.001) and decreased FMD (5.7 ± 2.9 vs. 10.3 ± 1.9 %, p &lt; 0.001) and GLS values (-18.6 ± 2.8 vs. -22.5 ± 2.3 %, p &lt; 0.001). In contrast, similar PWV values (9.2 ± 2 vs. 9.1 ± 1.9 m/s, p = 0.937) were recorded between patients and controls (Table). Increased IHS4 score (more severe disease) was associated with increased PBR values (r = 0.42, p = 0.026) and decreased FMD values (r = -0.37, p = 0.045).

Conclusion
Patients with HS show early impairment of endothelial and LV myocardial function, which correlates with the severity of the underlying systemic inflammation.Table
The potential effects of methotrexate on cardiovascular outcomes in rheumatoid arthritis patients: a multi-institutional analysis
Authors: Cervantes M , Miles B , Sills M 
Published: October 2024

Abstract

Introduction and Purpose
The association between rheumatoid arthritis (RA) and increased risk of developing cardiovascular disease has been previously described. Recent studies have also shown that methotrexate may reduce the risk of cardiovascular events in patients with RA but have been limited by small sample size and/or demographic constraints. Methotrexate is a first-line drug treatment for RA and works by suppressing multiple anti-inflammatory and immune reactions, thereby reducing the inflammation that promotes progression of cardiovascular disease in these patients. The goal of this study is to evaluate the potential benefit of methotrexate use on cardiovascular outcomes in patients with RA on a larger scale by utilizing a large international medical record database.

Methods
The TriNetX Diamond network was used for this study. Two cohorts were generated for comparison by using International Classification of Disease 10 (ICD-10) codes. Both cohorts included adult patients with a diagnosis of rheumatoid arthritis (M06) and both were excluded from being treated with the following biologic therapies: etanercept, infliximab, adalimumab, golimumab, and certolizumab pegol. One cohort was on active treatment with methotrexate while the other was excluded from being on it. The cohorts were then balanced for age, gender, race, ethnicity, presence of known coronary artery disease (I20-I25) and history of prior cardiovascular diseases (Z86.7) by propensity score matching and use of the greedy nearest neighbor algorithm. This resulted in 471,054 patients in each arm. They were then compared for the outcomes of acute myocardial infarction, chronic ischemic heart disease, congestive heart failure, and death at 5 years.

Results
Untreated RA patients were 11% more likely to develop myocardial infarction (RR 1.11, 95% CI (1.09,1.14), P value &lt;0.0001) and 14% more likely to develop chronic ischemic heart disease (RR 1.14, 95% CI (1.13,1.15), P value &lt;0.0001). CHF incidence was 21% higher (RR 1.21, 95% CI (1.19,1.22), P value &lt;0.0001) in the untreated group, but 5-year mortality in the two groups was comparable at around 8.2% (RR 0.98, 95% CI (0.97,0.997), P value 0.016).

Conclusion
This study confirms that methotrexate is associated with fewer cardiovascular events in RA patients, especially congestive heart failure. Although the use of methotrexate in patients with RA did not result in a mortality benefit, treatment may offer substantial improvements in patient morbidity and healthcare system cost. These benefits were seen in a sample of greater than 900,000 patients representing every adult demographic. These data reaffirm the previously described association between RA and cardiovascular disease and support the initiation of treatment with methotrexate for any adult patient with RA. Watchful waiting is associated with a higher incidence of adverse events in this population.
