Abstract

Background
Systemic sclerosis (SSc) is a chronic autoimmune disease characterized by widespread and progressive multi-organ fibrosis and vascular abnormalities. Endothelial dysfunction is an early manifestation of SSc and an important contributor to the progression and prognosis of the disease. Dynamic retinal vascular analysis (DVA) is a new method for non-invasive and precise determination of microvascular function. The primary aim was to assess micro- and macro-vascular function in patients with SSc.

Methods
In this study, vascular function was measured non-invasively with flicker-light induced vasodilation of retinal arterioles (FIDart) and branchial arterial flow-mediated vasodilation (FMD). Patients with SSc were prospectively enrolled in the study (n = 40; mean ± SD age 56±11 years, females 73 %) and compared with age- and sex-matched HC (n = 40; mean age 56±15 years, females 73%).

Results
Retinal microvascular function was significantly impaired in patients with SSc compared to matched HC (2.3±2.0% versus 3.1±1.9% respectively, p=0.04, figure 1). There was a trend for lower FMD in patients with SSc in comparison to HC (5.0± 3.2% versus 6.2±3.2% respectively, p=0.07).

Conclusion
Patients with SSc have severe impairment of retinal vascular function compared to matched HC. Thus, microvascular dysfunction in these patients is of systemic nature and retinal vessel analysis may serve as an important marker for SSc disease, severity and prognosis. These results set the stage for further studies on retinal function in SSc patients.Figure 1

Abstract

Background
In patients with intermediate coronary stenosis, the functional assessment with fractional flow reserve (FFR) and the anatomical assessment with optical coherence tomography (OCT) have been widely used in clinical practice. Additionally, coronary computed tomography angiography (CTA) is commonly used non-invasive imaging technique for evaluating suspected coronary artery disease before being referred for angiography.

Objectives
This study sought to investigate the association between FFR and plaque characteristics assessed by coronary CTA and OCT in intermediate coronary stenosis.

Methods
Based on the prospective multicentre registry, a total of 159 patients including 339 coronary lesions with intermediate stenosis were included. All patients underwent coronary CTA before being referred for coronary angiography and both FFR measurement and OCT examination were performed during angiography. The stenotic lesion with FFR ≤0.80 was considered diagnostic of lesion causing ischemia. The predictive value of plaque characteristics assessed by coronary CTA and OCT for identifying lesions causing ischemia was analyzed.

Results
Stenosis severity and plaque characteristics on coronary CTA and OCT were different between the lesions causing ischemia versus not causing ischemia. On multivariate analysis, low attenuation plaque on coronary CTA (odds ratio [OR]= 2.78; P=0.038) and thrombus (OR=5.13; 0.042), plaque rupture (OR=3.25; P=0.017), and intimal vasculature on OCT (OR=2.57; P=0.012) were independent predictors for the lesions causing ischemia. Increasing number of these plaque characteristics offered incremental improvement in predicting the lesions causing ischemia.

Conclusions
Comprehensive anatomical evaluation of coronary stenosis may be able to provide additional supportive information for predicting the lesions causing ischemia.

Published: October 2024

Abstract

Background
Chronic Chagas cardiomyopathy (CCC) is one of the leading causes of heart failure (HF) in Latin America and carries high morbidity and mortality. Previous studies showed conflicting results in epidemiological and clinical evidence of a gender-associated risk of death in patients with HF due to CCC.

Purpose
This study analysed the long-term prognosis and the main predictors of death in women and men with HF due to CCC.

Methods
From March 2009 to January 2023, we followed a cohort of outpatients with HF due to CCC. Specific serological tests diagnosed Chagas disease. Baseline data included clinical characteristics and echocardiographic findings. Statistical analyses were performed using the Kaplan-Meier (K-M) method to analyse time-to-event data and Cox proportional hazards methods to search for predictors of death.

Results
We studied 739 patients, with a mean age of 57.0 ± 12.1 years, 387 (52%) male. Women had a higher mean age (58.4 ± 11.7 vs. 55.8 ± 12.3 years; p=0.001), had a higher mean baseline left ventricular ejection fraction (LVEF) (44.3±14.5 % vs. 37.0±14.5%; p&lt;0.001) and a smaller left ventricular diastolic diameter (LVDD) (56.8±8.9 vs. 62.5±9.4 mm; p&lt;0.001). Over a median follow-up period of 10 years, 213 (56%) men and 169 (44%) women died (K-M: log-rank p=0.043; Figure). Men received more beta-blocker therapy (52.4% vs. 47.6%; p=0.040) and had a higher prevalence of chronic kidney disease (CKD) (p=0.003) and stroke (p=0.007). HFpEF was more prevalent in women and HFrEF in men (p&lt;0.001). Device implantation and transplant were similar between women and men. Cox regression analysis for death adjusted for age, sex, myocardial infarction, diabetes, CKD, stroke, atrial fibrillation (AF), and LVEF showed LVEF (HR= 0.98;95%CL:0.97-0.98), age (HR=1.03;95%CL1.02-1.04) and CKD (HR= 1.32;95%CL:1.10-1.64) as the main predictors of death. In men, the main predictors were age (HR=1.02;95%CL:1.01-1.04), CKD (HR=1.409;95%CL:1.07-1.86), and LVEF (HR=0.98;95%CL:0.97-0.99), and in women AF (HR=1.41;95%CL:1.03-1.91), age (HR=1.03;95%CL:1.01-1.04), and LVEF (HR=0.97;95%CL:0.96 -0.98).

Conclusion
women had a better prognosis than men, but gender was not an independent predictor of death. Prevention of comorbidities, especially CKD in men and AF in women, and higher beta-blocker therapy can significantly reduce the death rate in women and men with HF from CCC.

Abstract

Background
Breast arterial calcification (BAC) on mammography is associated with cardiovascular disease (CVD).1, 2 Given mammography is widely used as part of national breast cancer screening programs, routine reporting of BAC could address current limitations of CVD detection in women. Fully automated artificial intelligence (AI) software can facilitate seamless integration of BAC assessment alongside standard radiological evaluation of mammograms. and advancement in AI imaging software may result in clinically significant, superior BAC detection.

Purpose
To evaluate the performance of a deep-learning, fully-automated BAC detection algorithm against gold standard human BAC detection, and to evaluate its association with cardiovascular risk and disease.

Methods
A cohort of 285 women (mean age 61) with 2D digital mammography and CVD assessment with either an anatomic or functional test were evaluated. Cardiovascular risk factors were obtained from medical records. Visual BAC (vBAC) was assessed as present/absent by independent reviewers and BAC was scaled by an algorithm incorporating size, length, density and location (aBAC, 0-100). Diagnostic performance of vBAC and aBAC were compared and expressed as area under the receiver operator characteristic curve (AUC). Cardiovascular risk factor and disease prevalence was compared between vBAC and aBAC with CVD status defined by either abnormal anatomical or functional testing.

Results
The prevalence of vBAC and aBAC were 30.5% and 59.6%, respectively. The algorithm showed excellent discrimination for BAC detection compared with vBAC (AUC 0.92 [95% CI 0.89-0.98]), with sensitivity 94% and negative predictive value 96%. Interpretation took on average 144 seconds/patient with vBAC and 10 seconds/patient with aBAC (p&lt;0.001). We identified 88 discordant cases (vBAC negative, aBAC positive), which were all represented by ‘faint’ BAC scores (&lt;25). aBAC detected a greater proportion of patients with traditional cardiac risk factors, particularly in women &lt;65 years (Figure 1). CVD was present in 136 (48%), among whom 37.5% were detected by vBAC and 61.7% by aBAC. CVD was present in 42% of the 88 discordant cases. Increasing BAC score was associated with increased relative risk of CVD presence (Figure 2).

Conclusion
Algorithmic scoring of BAC demonstrates a high performance and is faster to perform when compared to vBAC. Furthermore, it identifies greater proportion of women with higher cardiovascular risk and those with prevalent CVD. Lastly, aBAC detects ‘faint’ (visually missed) lesions that may have significant clinical implications.

Published: October 2024

Abstract

Background
Premature/early menopause increases the risk of future cardiovascular disease (CVD); however, whether lifestyle can offset this risk is unknown.

Purpose
Investigate the association between premature/early menopause and incident CVD and whether a healthy lifestyle modifies this association.

Methods
The 45 and Up Study prospectively recruited participants aged ≥45 years (n=267,357) between 2005-2009. Our study included women without prior CVD and those reporting menopausal age at baseline. Primary outcome was incident CVD (self-reported heart disease/stroke) based on survey data1 at Wave 2 (2012-2015) and/or Wave 3 (2018-2020). Logistic regression models assessed associations of premature (age &lt;40 years) and early (age 40-44 years) menopause with CVD, compared to standard menopause (age 50-52 years), adjusting for sociodemographic and clinical variables. Healthy lifestyle adherence was assessed using a score of five factors: smoking, physical activity, sitting, sleep, and diet. Interaction effects were analysed between menopause and healthy lifestyle adherence on CVD.

Results
We included 46,273 women (mean age 62.1±8.2 years), with 5,425(11.7%) incident CVD over 15-year follow-up. After adjustment, the CVD risk was higher in women with premature menopause (odds ratio (OR): 1.36, 95% confidence intervals (CI), 1.17-1.59; p&lt;0.0001) and early menopause (OR: 1.15, 95% CI, 1.03-1.28; p=0.013) compared to standard menopause. Among all menopausal women, high versus low healthy-lifestyle adherence led to 20% lower CVD risk (OR: 0.80, 95% CI, 0.71-0.90; p=0.0003). In the subset of high-risk women with premature menopause, high versus low healthy lifestyle adherence led to 50% lower risk of CVD (OR: 0.50, 95% CI, 0.31-0.80, p=0.0040). The healthy lifestyle effect was not significantly different across menopause groups (p=0.71).

Conclusion
Early and premature menopause were independently associated with increased CVD risk. Healthy versus unhealthy lifestyle significantly attenuated the risk of CVD in all menopausal women, particularly in the highest risk group of women with premature menopause, reducing this risk by 50%.

Authors: Zhao J , Fang C , Chen Y , Xu X , Zhao R , Dai J , Yu B 
Published: October 2024

Abstract

Background
Non-culprit plaque rupture (PR) had widespread nature in patients with acute coronary syndrome, indicating generalized acute destabilization. However, morphological features and long-term outcomes of non-culprit PR in acute myocardial infarction (AMI) patients have not been systemically investigated.

Objectives
We aimed to investigate the pancoronary picture (plaque characteristics and location) and long-term outcomes of non-culprit PR in AMI patients.

Methods
From January 2017 to May 2019, 3757 non-culprit plaques were analyzed in 883 AMI patients treated by 3-vessel optical coherence tomography. Patients and lesions were divided into two groups based on the presence or absence of non-culprit PR. All patients enrolled were followed for up to four years.

Results
Non-culprit PR was found in 178 patients (20.2%) and 200 lesions (5.3%). Patients with non-culprit PR had a more non-culprit lesions (NCLs) (p &lt; 0.001), diseased arteries (p &lt; 0.001) and multi-vessel disease (p &lt; 0.001) compared with patients without non-culprit PR, both in angiography and OCT analyses. In vulnerable plaque feature, non-culprit PR group had higher incidence of thin-cap fibroatheroma (TCFA) (p &lt; 0.001; p &lt; 0.001), minimal lumen area (MLA) &lt; 3.5mm² (p = 0.004; p = 0.012), CLIMA-defined high-risk plaque (p &lt; 0.001; p &lt; 0.001), thrombus (p &lt; 0.001; p &lt; 0.001), lipid rich plaque (p &lt; 0.001; p &lt; 0.001), calcification (p &lt; 0.001; p &lt; 0.001), macrophage (p &lt; 0.001; p &lt; 0.001), microchannel (p &lt; 0.001; p &lt; 0.001), cholesterol crystals (p &lt; 0.001; p &lt; 0.001), and layered tissue (p &lt; 0.001; p &lt; 0.001) compared with the other group, in patient and lesion level. In addition, non-culprit PR was highly populated at "hot spots" in the right coronary artery (56.5% vs. 40.2%; p &lt; 0.001), and the originally treated culprit artery (33.5% vs. 25.2%; p = 0.008), and tended to cluster proximal to the coronary ostium [26.1 (15.5-38.0) vs. 29.4 (15.8-44.5); p = 0.009]. Multivariate analysis identified the NCL in the initially treated culprit artery (odds ratio [OR]: 1.874, 95% confidence interval [CI]: 1.230–2.857, p = 0.003), distance from coronary ostium to MLA site (OR: 0.987, 95% CI: 0.978–0.997, p = 0.008), mean lipid arc (OR: 1.006, 95% CI: 1.003–1.010, p = 0.001), TCFA (OR: 15.870, 95% CI: 10.259–24.551, p &lt; 0.001), thrombus (OR: 4.333, 95% CI: 2.346–8.003, p &lt; 0.001), and microchannel (OR: 1.679, 95% CI: 1.136–2.482, p = 0.009) were independent predictors of non-culprit PR. Non-culprit PR showed higher 4-year rates of NCL-related major adverse cardiac events in the patient (14.0% vs. 5.1%; p = 0.001) and lesion (6.5% vs. 0.9%; p &lt; 0.001) levels.

Conclusions
NCLs with non-culprit PR had a unique pancoronary picture (pancoronary vulnerability and "hot spots") and worse long-term outcomes in AMI patients.
High eosinophil counts aid in diagnosing Kawasaki disease in febrile children
Authors: Huang Y H , Kuo H C , Tsai C M 
Published: October 2024

Abstract

Background
Several recent studies have validated the newfound significance of elevated eosinophils in Kawasaki disease (KD). However, this finding was not incorporated into the suggested laboratory criteria outlined by the Kawasaki Disease Committee of the American Heart Association for assessing children with incomplete KD.

Purpose
We aimed to determine the potential benefits of including eosinophil levels in the laboratory evaluation of KD.

Methods
A retrospective cohort study involved 77,934 febrile children (FC, not KD) and 1,970 subjects diagnosed with KD. Participants were recruited from four hospitals, comprising two medical centers and two regional hospitals. The AHA recommends specific laboratory tests—white blood cell count, hemoglobin, platelet count, ALT levels, albumin, and urinalysis—for evaluating incomplete KD in children with a higher CRP than 30mg/dL. The first four items are standard blood assays. Additionally, we introduced high eosinophil counts as a new diagnostic criterion for identifying children with KD.

Results
All these five laboratory findings (anemia for age defined as below the 5th percentile), platelet count &gt;450,000/mm3, white blood cell&gt;15,000/mm3, ALT&gt;40 U/L, and eosinophil count &gt;190/mm3) are significantly different between KD children and FC. The proportion of having these features is higher in KD children than in FC (19.3% vs. 8.0% in anemia for age, 20.5% vs. 10.3% in thrombocytosis, 37.0% vs. 18.1% in leukocytosis, 45.7% vs. 5.8% in elevated ALT, and 62.6% vs. 29.3% in high eosinophils). Elevated eosinophil counts are most commonly associated with KD among these five parameters. Furthermore, when incorporating the parameter of elevated eosinophil counts, the proportion of KD children with at least two abnormalities rose from 35.4% to 60.7%. In a subgroup analysis of children with KD presenting at least two abnormalities, the proportion rose from 38.7% to 63.5% in the high CRP group (≧ 3.0 mg/L) and 21.6% to 49.0% in the low CRP group (&lt; 3.0 mg/L), respectively.

Conclusions
Higher eosinophil counts are vital markers in KD children. This aids in the identification of additional potential KD cases, especially in those exhibiting low CRP levels.

Abstract

Background
Fifty years after the first Fontan operation, the persisting challenges and evolving landscape of post-Fontan complications are explored in the EUROFONTAN experience. Aim of the study is the evaluation of long term outcomes of a large cohort of Fontan patients, focusing on age at Fontan and onset of Fontan-associated liver disease (FALD).

Methods
A retrospective clinical study across 21 european congenital cardiac centers across Europe. Clinical and operative data of patients who underwent Fontan operation between January 1990 and December 2022 were gathered through a RedCap online database.

Results
2606 patients were included in this analysis (M/F: 59%/41%, median age and median weight at Fontan of 4.3 y.o (IQR 3.3-6.4), and 16kg (IQR 14-20), respectively. Most frequent cardiac anomaly were tricuspid atresia and pulmonary atresia with intact ventricular septum (781, 30%). Ventricular morphology was left in 1379 patients (53%), and right in 1029 patients (40%). Extra cardiac conduit (ECC) was performed in the majority of patients (2335, 90%), with a median conduit size of 20mm (IQR 18-20). Early post-operative complications were present in 52% (1340), with an early reintervention in 349 patients (249 surgical , 99 catheter driven)
At a median follow-up median of 10 years (IQR 4-15), there were 79 late deaths (3%). Adverse events occurred in 49% (1288 , non-surgical in 962 , surgical in 249). The clinical status was stage A in 60% (1288 patients), while only a minority (1.3%) was in status D. Systemic Ventricular function was normal in 1898 patients (73%), while absent or mild Atrioventricular Valve regurgitation was presnet in 86% (1816). Of note, FALD was detected in 388 (15 %) , and sinus rhythm was present in 99%.
Statistical analysis shows that late death and adverse events are significantly associated right ventricular morphology of the systemic ventricle (p-value 0.019). Of note, when compared to lateral tunnel, TCPC extracardiac conduit demonstrated lower late mortality (2.3% vs 8.2%, p-value &lt;0.001) and complication rates (60% vs 48%, p-value 0.001). Analyzing age at Fontan, a linear relationship exists between age and late mortality, whereby mortality increases with advancing age (graph 1). However, concerning the development of late adverse events, the risk decreases with age at Fontan up to 7 years; beyond 7 years, the risk increases with advancing age (graph 2). The analysis demonstrated growing FALD-prevalence with increasing time from Fontan completion (significant especially after 10 years).

Conclusion
current long term outcomes of Fontan operation are highly satisfactory. However, the longer survival is associated to an increasing incidence of late term extracardiac complications (namely FALD) which are more evident if Fontan is performed at older age.Data of Fontan PatientsCorrelation between age at Fontan and AE

Abstract

Background
Infants born small for gestational age (SGA) or diagnosed with fetal growth restriction (FGR) are at increased risk of neonatal mortality as well as cardiovascular disease later in life. Previous studies based on smaller cohorts (n&lt;200) of newborns with SGA and FGR (n&lt;200) have demonstrated structural and morphological alterations in the heart compared to infants born appropriate for gestational age (AGA). However, to our knowledge no previous study has systematically investigated the effect of SGA and FGR on echocardiographic parameters in the infant heart.

Purpose
To investigate whether echocardiographic parameters differ among infants born SGA or with FGR, in comparison to infants born AGA.

Methods
This study is a population-based cohort study of infants (n&gt;25,000) offering postnatal cardiac examination including transthoracic echocardiography (TTE) between 2016-2018. We compared left ventricular (LV) TTE parameters in infants born SGA (birthweight ≥3rd and &lt;10th percentile, n=2,106) and with FGR (birthweight &lt;3rd percentile, n=972) with infants born AGA (birthweight ≥10th and &lt;90th percentile, n=20,468) using a multiple linear regression analysis. We have investigated LV volumes, systolic function, diastolic function, and LV structure. All analyses were adjusted for sex, gestational age at birth, weight, length, and age at cardiac examination.

Results
Infants born SGA had higher heart rates compared with infants born AGA. Both infants born SGA and infants with FGR had significantly smaller LV dimensions including septal and posterior wall thicknesses (IVSd and LVPWd), and LV internal diameters (LVIDd and LVIDs). Infants born SGA had smaller end-diastolic and end-systolic volumes compared with infants born AGA (Table 1). Infants born SGA or with FGR had significantly higher mitral valve early peak velocities, compared with infants born AGA, and infants born SGA showed increased mitral valve atrial peak velocities indicating altered diastolic function (Table 1).

Conclusion
Infants born with inadequate intrauterine growth had smaller LV dimensions compared with infants born AGA, even when adjusting for infant size and age. Infants born SGA and with FGR both exhibited altered diastolic function. Longitudinal studies of children with inadequate intrauterine growth are needed to determine the impact on adult cardiac health.
