Trends in success rate after percutaneous transluminal coronary angioplasty in men and women with coronary artery disease.

Women with coronary artery disease are less likely to undergo percutaneous transluminal coronary angioplasty (PTCA) because of the potential referral bias in favor of men with coronary artery disease in the use of invasive diagnostic procedures and interventions. This difference may represent a sex bias in the delivery of medical care. The apparent sex difference in short-term success of PTCA seen in the early 1980s has not persisted in subsequent studies. The higher in-hospital mortality rate, if any, in women compared with men after PTCA is related more to the severity of their underlying disease rather than sex alone. In addition, women have a better long-term PTCA success rate. PTCA should not be withheld in women who are considered appropriate anatomic candidates for fear of reduced success or increased major complications.
