    Abstract:
    The differences in clinical characteristics were studied between variant angina pectoris with ST segment elevation during ischemic attacks and non-variant angina pectoris without ST segment elevation. Spasm provocation test was performed with either acetylcholine or ergonovine in 192 consecutive patients with vasospastic angina from January 1991 to June 1997. Thirteen patients were excluded because of insufficient data. Fifty-five patients had variant angina and 124 patients had non-variant angina. Coronary risk factors, serum cholesterol level, triglyceride level, high-density lipoprotein cholesterol level, history of syncope, the rates of second or third atrioventricular block and ventricular tachycardia or fibrillation, the incidence of organic stenosis (> or = 50%), the number of vessels with provoked spasm, the dose of acetylcholine and ergonovine used, and duration from the first appearance of chest pain were compared between the 2 groups. Patients with variant angina had more fixed stenosis (p < 0.01), required more percutaneous transluminal coronary angioplasty procedures, lower doses of intracoronary administration of acetylcholine for the induction of coronary arterial spasm and shorter duration from the first appearance of chest pains (p < 0.01) than patients with non-variant angina. However, there were no differences in other factors between the 2 groups. Variant angina pectoris has the same clinical characteristics as non-variant angina pectoris, although variant angina tends to cause higher spasmophilic activity and more fixed stenosis.
