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.
Diagnosis
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.
