Abstract :
Background: There are limited studies on gender differences in patients with unstable angina. We investigated the influence of gender in these patients in a tertiary referral centre. Methods and results: Three hundred and thirteen consecutive patients (210 men and 103 women) with unstable angina were studied over a 42-month period. Patient characteristics, cardiovascular risk factors and subsequent management including coronary artery bypass graft (CABG) operation and percutaneous transluminal coronary angioplasty (PTCA) were investigated. There was no difference in age [61.6 (11.0) (S.D.) years for men vs. 63.5 (10.5) years for women]. Diabetes mellitus and hypertension were more common in women (diabetes, 11% vs. 23%, P=0.007; hypertension, 32% vs. 52%; P=0.001). The number of smokers was greater in men (73% vs. 46%, P=0.00001). There was no difference in the prevalence of hypercholesterolaemia or in the incidence of previous myocardial infarction, previous history of angina and family history of ischaemic heart disease. The duration of unstable angina before presentation to the referring hospital was similar in both sexes. The use of aspirin, intravenous heparin and antianginal drugs was also comparable in the two genders. The number of coronary arteries involved in men and women appeared similar (one vessel, 22% vs. 27%; two vessels, 26% vs. 21%; three vessels, 52% vs. 52% in men and women, respectively). The proportion of men and women who underwent subsequent revascularisation was also similar (CABG, 31% vs. 33%; PTCA, 42% vs. 40%). The overall in-hospital mortality was higher in women (6.8% vs. 2.8%), but was not statistically significant (P=0.18). Conclusions: Gender differences in unstable angina manifest in the preponderance of selected risk factors including diabetes mellitus and hypertension in women and smoking in men. There is no difference in age, the degree of coronary artery involvement and the subsequent management in a tertiary referral centre.
