CAD status coded as (non-CAD, CAD, MI, MI with acute HF). MI: myocardial infarction, heart failure (HF) coded as (acute HF, chronic HF, no HF), intervention coded as (CABG, PCI, and no intervention) LVEF: left ventricular ejection fraction, LA: left atria, % Increase in LVEF=((LVEF at 30days−LVEF at baseline)/LVEF at baseline)*100, β is the standardized coefficient (slope/std error).
