The medical management of chronic stable angina.

Echocardiography provides information about left ventricular function, and regional wall motion abnormalities that may be related to infarction or ischaemia. In patients with stable coronary artery disease, left ventricular ejection fraction is the strongest predictor of long-term survival. The 12-year survival of medically treated patients with ejection fractions greater than 50% is 73%, and 54% if the ejection fraction is between 35% and 49%. Survival is only 21% if the ejection fraction is less than 35%.8
