Prinzmetal's variant angina.
Two patients are described with a typical Prinzmetal's variant angina. Both patients were young, active males with angina of recent onset. They experienced angina only at rest and in one patient the angina had a cyclic character appearing only between 4 and 10 a.m. In both patients there was no correlation whatsoever between the angina pectoris and effort, emotion or change in temperature and the angina reacted promptly to nitroglycerine sublingually. The number of attacks and the intensity of the pain were increasing rapidly over a short period of time in both cases. The stenoses in both patients did not exceed 50% of the lumen of the coronary arteries, but coronary surgery has been performed on clinical grounds because both patients were completely disabled and one of them suffered from life-threatening dysrhythmias. For respectively 18 and 6 months after saphenous vein bypass surgery both patients have been symptom-free and able to resume their work. The problems concerning the diagnosis Prinzmetal's variant of angina pectoris are discussed.
