چکیده

Thirty-five patients with typical Prinzmetal's variant angina were studied by coronary cineangiography. There was no demonstrable stenosis of the major coronary arteries in 19 patients. Nine patients with single coronary stenosis underwent aortocoronary bypass and had recurrence of the symptoms postoperatively. Administration of nifedipine effected complete cessation of the symptoms among patients formerly treated medically. Although surgical treatment did not effect permanent relief of pain, all patients initially treated surgically experienced relief of pain when nifedipine was administered. The pathophysiology of variant angina remains obscure. Our results suggest that neurohumoral factors exert more of an effect on the myocardial cell than on the coronary vessels.

Prinzmetal's variant angina associated with severe heart rhythm disturbances and syncope: a therapeutic dilemma.

Prinzmetal's angina is a distinct syndrome characterized by episodes of chest pain and transient ST-segment elevation caused by coronary vasospasm. This variant form of angina is sometimes associated with complete atrioventricular block and ventricular arrhythmias. We report here a case of variant angina with documented severe heart rhythm disturbances and syncope in a 66 year-old woman. Due to...

Continuous electrocardiographic recording in Prinzmetal's variant angina pectoris. A report of four cases.

Four patients with Prinzmetal's variant angina pectoris were subjected to continuous electrocardiographic recording. In three of them several episodes of ST segment elevation unaccompanied by pain were recorded. In one patient, identical electrocardiographic alterations were observed both in presence or in absence of pain, while in the others a good correlation was evident between pain and seve...
