Heart Attack Causes If you have coronary artery disease, those arteries become narrow, and blood can’t flow as well as it should. When your blood supply is blocked, you have a heart attack. Fat, calcium, proteins, and inflammatory cells build up in your arteries to form plaques.

What are the pathophysiological mechanisms that can lead to heart failure?

Heart failure results from injury to the myocardium from a variety of causes including ischemic heart disease, hypertension, and diabetes. Less common etiologies include cardiomyopathies, valvular disease, myocarditis, infections, systemic toxins, and cardiotoxic drugs.

Can stress cause heart attack?

Stress may lead to high blood pressure, which can pose a risk for heart attack and stroke. Stress also may contribute to such cardiovascular disease risks as smoking, overeating and lack of physical activity. “Chronic stress has been shown to be associated with increased cardiovascular events,” Schiffrin said.
