Atrial and ventricular mechanical dysfunction and myocardial injury predict long-term outcomes in hypertrophic cardiomyopathy: a retrospective cohort study
Background Left ventricular (LV) diastolic dysfunction is a hallmark of hypertrophic cardiomyopathy (HCM) and imposes chronic pressure overload on the left atrium, leading to progressive atrial remodeling and functional impairment. Conventional left atrial (LA) volumetric indices reflect comparatively advanced structur...
