Background Black individuals have a higher burden of risk factors for heart failure (HF) and subclinical left ventricular remodeling. Methods and Results We evaluated 1871 Black participants in the Atherosclerosis Risk in Communities Study cohort who attended a routine examination (1993-1996, median age 58 years) when they underwent echocardiography. We estimated the prevalences of 4 HF stages: (1) : no risk factors; (2) : presence of HF risk factors (hypertension, diabetes mellitus, obesity, smoking, dyslipidemia, coronary artery disease without clinical myocardial infarction), no cardiac structural/functional abnormality; (3) : presence of prior myocardial infarction, systolic dysfunction, left ventricular hypertrophy, regional wall motion abnormality, or left ventricular enlargement; and (4) : prevalent HF.

Article Synopsis
  • Increased carotid intima-media thickness and interadventitial diameter are significant predictors for dementia, indicating a link between vascular health and cognitive decline.
  • A study of 12,459 participants showed that individuals in the highest quintiles for these measurements had a notably increased risk of developing dementia over a median follow-up of 24 years.
  • Interestingly, while carotid plaque presence showed no significant connection to dementia, higher arterial distensibility was linked to a lower risk, implying that improved vascular function may protect against cognitive impairment.

Background Although Black adults are more likely to die from coronary heart disease (CHD) compared with White adults, few studies have examined the relationship between cigarette smoking and CHD risk among Black adults. We evaluated the relationship between cigarette smoking, incident CHD, and coronary artery calcification in the JHS (Jackson Heart Study). Methods and Results We classified JHS participants without a history of CHD (n=4432) by self-reported baseline smoking status into current, former (smoked at least 400 cigarettes/life) or never smokers at baseline (2000-2004).

Background QRS duration (QRSd) is a marker of electrical remodeling in heart failure. Anthropometrics and left ventricular size may influence QRSd and, in turn, may influence the association between QRSd and heart failure outcomes. Methods and Results Using the prospective, multicenter, multinational ASIAN-HF (Asian Sudden Cardiac Death in Heart Failure) registry, this study evaluated whether electroanatomic ratios (QRSd indexed for height or left ventricular end-diastole volume) are associated with 1-year mortality in individuals with heart failure with reduced ejection fraction.

Background Impairment of glycolytic metabolism is suggested to contribute to diabetic cardiomyopathy. In this study, we explored the roles of SIRT3 (Sirtuin 3) on cardiomyocyte glucose metabolism and cardiac function. Methods and Results Exposure of H9c2 cardiomyocyte cell lines to high glucose (HG) (30 mmol/L) resulted in a gradual decrease in SIRT3 and 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase isoform 3 (PFKFB3) expression together with increases in p53 acetylation and TP53-induced glycolysis and apoptosis regulator (TIGAR) expression.

Background Atrial fibrillation (AF) is a risk factor for cognitive decline, possibly from silent brain infarction. Left atrial changes in structure or function (atrial cardiopathy) can lead to AF but may impact cognition independently. It is unknown if AF or atrial cardiopathy also acts on Alzheimer disease-specific mechanisms, such as deposition of β-amyloid.
