Abstract
Background— Women with acute myocardial infarction (AMI) undergoing primary angioplasty have higher rates of morbidity and mortality than do men. Whether contemporary interventional treatment strategies have improved outcomes for women compared with men is unknown. Methods and Results— In the CADILLAC trial, 2082 patients (27% women) with AMI within 12 hours of symptom onset were randomized to balloon angioplasty (PTCA; n=518), PTCA+abciximab (n=528), stenting (n=512), and stenting+abciximab (n=524). As compared with men, women had a lower body surface area; had a greater prevalence of diabetes, hypertension, and hyperlipidemia; experienced significant delays to treatment; and had better baseline and final TIMI grade 3 flows. Unadjusted 1-year event rates were higher for women, including death (7.6% versus 3.0%, P<0.001), ischemic target-vessel revascularization (TVR; 16.7% versus 12.1%, P=0.006), and major adverse cardiac events (MACE; 23.9% versus 15.3%, P<0.001). Female gender was an independent predic...
