CLINICAL MEDICINE

Detailed explanation-1: -A heart attack is the most common cause of cardiogenic shock. Less often, another heart problem or a problem somewhere else in the body blocks blood flow coming into or out of the heart and leads to cardiogenic shock.

Detailed explanation-2: -The most common cause of cardiogenic shock is acute MI. Often, anterior MI from acute thrombotic occlusion of the left anterior descending artery results in extensive infarction. Alternatively, a smaller MI in a patient with borderline left ventricular function may be responsible for insufficient cardiac output.

Detailed explanation-3: -Common causes of myocardial dysfunction that lead to shock include cardiomyopathy, myocarditis, arrhythmias, congenital heart disease, and the postoperative period after cardiac surgery.
