Comparing left atrial indices by CMR in association with left ventricular diastolic dysfunction and adverse clinical outcomes.

Left atrial (LA) features are altered when diastolic dysfunction (DD) is present. The relations of LA features to the DD severity and to adverse outcomes remain unclear using CMR images. We sought to compare LA features including volumes, emptying fraction, and strains as predictors of left ventricular (LV) DD and adverse outcomes.

The Association between Left Ventricular Diastolic Dysfunction and Myocardial Scar and Their Collective Impact on All-Cause Mortality.

Background: Left ventricular diastolic dysfunction (DD) and myocardial scar are important contributors to cardiovascular morbidity and mortality. The aim of this study was to test the hypothesis that myocardial scar is a substrate of DD and that collectively they contribute to increased risk for all-cause mortality.

Methods: The study included 607 consecutive patients who underwent echocardiography and cardiac magnetic resonance imaging within 1 week.
