Objectives. The purpose of this study was to determine whether there are gender differences in the outcome of percutaneous transluminal coronary angioplasty performed for postmyocardial infarction ischemia.
Background. Although women have a higher mortality rate after myocardial infarction than that of men, they are less frequently referred for coronary angioplasty (and coronary artery bypass graft surgery) than are men, possibly because of expectations of a worse procedural outcome.
Methods. We analyzed the morbidity and mortality at coronary angioplasty and during a mean follow-up period of 34.4 months for women and 34.2 months for men in 505 consecutive patients (164 women and 341 men) with postmyocardial infarction ischemia between 1981 and 1989.
Results. Compared with men, women had similar procedural success rates (89.6% and 91.2%, respectively), need for coronary artery bypass surgery (3.7% and 2.6%) and mortality rates at coronary angioplasty (0.6% and 0.9%). During the follow-up period there were no significant gender differences in the requirement for coronary artery bypass surgery (3.6% and 4%), repeat angioplasty (18.7% and 17.3%), reinfarction (5.8% and 6%) and death (3.6% and 3.7%) or the combined end points of all four events (26.6% and 26.6%). Women had significantly more recurrent angina than did men (54% vs. 42.5%, p < 0.01), even though the extent of coronary artery disease and frequency of incomplete revascularization were similar in men and women.
Conclusions. The procedural outcome of coronary angioplasty for postmyocardial infarction ischemia is similar in women and men. Long-term follow-up is also similar except that women experience an increased incidence of recurrent angina, an outcome also reported after bypass surgery. Therefore, concerns over the safety of coronary angioplasty in women should not adversely influence decisions concering referral of women for coronary angioplasty after myocardial infarction complicated by ischemia.
