Repetitive myocardial ischemia of Prinzmetal type without angina pectoris.
In a patient with a normal electrocardiogram, normal treadmill exercise test, normal coronary arteriogram and no symptoms to suggest angina pectoris, continuous monitoring during several days exhibited repetitive (one to two per hour) S-T segment elevations in the precordial electrocardiographic leads and hemodynamic changes typical of Prinzmetal's angina (reduction in arterial pressure and cardiac index and increase in systemic peripheral resistance and pulmonary wedge pressure). This case demonstrates that electrical and dynamic cardiac alterations of Prinzmetal's angina can occur even in the absence of angina pectoris.
