Hemodynamics and prognosis of patients with angina pectoris without coronary heart disease (syndrome X).

abstract：:Physical training causes an increase of aerobic capacity in normal and cardiac patients. The influences of training plus placebo and training plus verapamil have been studied in a double-blind randomized trial on 40 patients recovering from actue myocardial infarction.
