Abstract 4363833: Impact of Damaging Genetic Variants on Right Ventricular Function in Tetralogy of Fallot
Background: Right ventricular (RV) dysfunction is an important determinant of outcomes in many forms of CHD. However, clinical and imaging biomarkers explain only 25% of the variab...
Abstract 4341724: Progression of Left Atrial Volume Is Associated with Mitral Annular Calcification: Findings from MESA
Background: The relationship between MAC burden and left atrial volume (LAV) progression over time has not been well characterized. Identifying whether MAC contributes to atrial re...
Abstract 4344088: Cardiac Arrest in a Postpartum Female with Congenital Long QT Syndrome
Background: Long QT syndrome (LQTS) is an arrhythmogenic channelopathy that increases the risk of fatal arrhythmias. Limited data exist regarding the arrhythmogenic risk associated...
Abstract 4369915: Direct Vascular Endothelial Assessment Highlights the Pleotropic Anti-Inflammatory Properties of Statin Therapy: Findings from the American Heart Association Cardiometabolic Health Strategically Focused Research Network
Background: Statins are central to cardiovascular (CV) prevention, primarily for their lipid-lowering effects, but may also offer anti-inflammatory benefits. This study compared th...
Abstract 4359042: Cancer Patients With Incidental Coronary Artery Calcification Receive Less Preventive Cardiovascular Care: A Propensity-Matched Cohort Study
Introduction: Incidental coronary artery calcification (CAC) frequently appears on routine chest CT scans and indicates high risk for future atherosclerotic cardiovascular events,...
Abstract 4361608: Clinico-imaging Profile and Correlations of Global Longitudinal Strain Abnormalities in Indian Hypertrophic Cardiomyopathy patients
Background: Hypertrophic cardiomyopathy (HCM) is a common genetic cardiac disorder with heterogeneous clinical expression. While global data on HCM phenotypes are available, there...
Abstract 4364350: Impact of Prior Myocardial Infarction on the Outcomes of Chronic Total Occlusion Percutaneous Coronary Intervention
