Left ventricular dysfunction following myocardial infarction

Left ventricular dysfunction following myocardial infarction refers to impaired mechanical performance of the heart's main pumping chamber resulting from ischemic myocardial necrosis and adverse ventricular remodeling Pathophysiologically, the loss of viable myocardium triggers neurohormonal activation, wall thinning, chamber dilation, and progressive interstitial fibrosis, which collectively reduce cardiac output and elevate intracardiac filling pressures

This cardiovascular complication predominantly affects patients who have survived an acute coronary event, manifesting as depressed systolic contractility, impaired diastolic filling, or reduced left ventricular ejection fraction

Clinically, affected individuals may remain asymptomatic or exhibit signs of congestive heart failure, such as dyspnea, fatigue, pulmonary congestion, and an elevated risk for malignant ventricular arrhythmias
