Mixed angina pectoris


 * Associate Editor-In-Chief:

Overview
Mixed or variable threshold angina pectoris is a syndrome in which there is substantial variation in the magnitude of physical activity or provocation that induces anginal chest pain.

Pathophysiology

 * Dynamic vasoconstriction which superimposed on fixed atherosclerotic coronary artery obstructions has been postulated as the underlying pathophysiologic mechanism for the variable exercise threshold.

Symptoms

 * The essential clinical feature of mixed angina is a substantial variation in the degree of physical activity that induces angina.
 * These group of patients may also experience rest or nocturnal angina on certain occasions.
 * Angina may also occur on exposure to cold, during emotional stress, or after meals.

Treatment

 * The treatment is the same as chronic stable angina.
