Angina is a clinical syndrome caused by temporary ischemia of the myocardium due to the imbalance between supply and demand of myocardial oxygen. This article reports 4 patients with exercise-induced angina, confirmed by coronary angiography angina pectoris is caused by large branches of coronary artery spasm, and with a variety of drugs to observe the effect of prevention and treatment of angina. Diagnostic methods and results Four patients underwent treadmill exercise tests and continuous ECG monitoring. All patients had recurrent angina pectoris, changes in myocardial ischemia associated with electrocardiography, and the following agents were used on separate days. 4 cases were given propranolol 60mg and sulfur nitrogen (艹 Zhuo) ketone 90mg, 3 cases of nifedipine 20mg, 3 cases of intramuscular injection of phentolamine 0.2mg / kg, in
