Association of Asymptomatic Diastolic Dysfunction Assessed by Left Atrial Strain With Incident Heart Failure

This study is to establish the association of left atrial reservoir strain (LARS) with incident heart failure (HF), and the impact of substituting LARS for left atrial (LA) volume index (LAVI) in diastolic assessment. LARS measures passive LA stretch and is a sensitive marker of left ventricular diastolic dysfunction (DD). The potential contribution of LARS to diastolic assessment is unclear. Baseline clinical and echocardiographic assessments...
