II. PATHOPHYSIOLOGY A. Overview
Fortunately, no damage happens to the heart muscle during an attack of angina. Full recovery occurs within minutes of the attack. Many patients have several episodes of this fleeting pain or discomfort a few times monthly for over 15 years and learn to cope with the minor restrictions to their lifestyle. In some individuals, angina that is well controlled or stable worsens causing unstable angina that requires special therapy; some patients go on to have heart attacks.
