Objective To assess the clinical features of female patients with AMI and their out-comes .Methods Two hundred and eighty-four AMI patients (216 males and 68 females) were in-cluded in this study .Their clinical features ,complications ,PCI and outcomes were comared .The patients were followed up for 3 months ,during which the major adverse cardiac events (MACE) were observed with their mortality and risk factors for MACE assessed .Results The age was ol-der and the heart rate ,TIMI grade ,GRACE score were significantly higher in female patients than in male patients (P<0 .05 ,P<0 .01) .The ratio of female patients who underwent PCI was signif-icantly lower than that of male patients who underwent PCI (30 .9% vs 48 .6% ,P=0 .012) .The in hospital mortality was higher in female patients than in male patients (17 .6% vs 9 .3% ,P=0.077) ,and the incidence of MACE in a 3-month follow-up period was significantly higher in fe-male patients than in male patients (27 .9% vs 15 .7% ,P=0.032) .Multivariate logistic regression analysis showed that age and Killip classification were the independent risk factors for in hospital mortality (OR=1 .078 ,95% CI:1 .035 -1 .123 ,P=0 .000 ;OR= 1 .901 ,95% CI:1 .373 -2 .633 , P=0 .000) and for MACE in a 3-month follow-up period (OR=1 .040 ,95% CI:1 .008 -1 .074 , P=0 .015;OR=1 .543 ,95% CI:1 .170-2 .034 ,P=0 .002) .PCI was a protective factor for MACE in a 3-month follow-up period (OR=0 .090 ,95% CI:0 .026-0 .306 ,P=0 .000) .Conclusion The age of female AMI patients is older and their heart function is poorer with a higher risk of MACE and a less chance for PCI .However ,gender itself is not an independent predictor for in hospital mortality and M ACE in a 3-month follow-up period .
