The most common cause of CHF is?

The main idea is identifying the most common underlying disease that progresses to congestive heart failure. Coronary artery disease is the leading cause, because ischemic damage from CAD often leads to myocardial scar and systolic dysfunction (ischemic cardiomyopathy), which reduces the heart’s pumping ability and drives heart failure. Hypertension plays a huge role as a risk factor and often leads to heart failure over time, especially causing diastolic dysfunction, but when asked for the single most common cause, CAD typically leads the list. Valvular disease and arrhythmias can cause heart failure too, but they are less commonly the primary etiology compared with CAD.
