[Impact of gender and age on in-hospital major adverse cardiovascular and cerebrovascular events of patients with acute ST-segment elevation myocardial infarction].

To investigate the impact of gender and age on in-hospital major adverse cardiovascular and cerebrovascular events of patients with acute ST-segment elevation myocardial infarction (STEMI). This is a retrospective single-center study. A total of consecutive 1 102 patients with acute STEMI admitted to our hospital from January 2001 to December 2010 were recruited and clinical data were analyzed. The primary end point was in-hospital death due to any cause, and the secondary end point was in-hospital composite end point including death, re-infarction and stroke. Multivariate logistic regression analyses were performed to identify the risk factors of in hospital death and composite end point. The study population included 283(25.7%(283/1 102)) female patients and female patients were older than male patients ((68.7±11.2)years vs. (59.2±12.5)years, <0.001). Compared with male patients, less female patients received primary percutaneous coronary intervention (50.9%(144/283) vs. 70.9%(581/819), <0.001), had higher rates of in hospital death(10.6%(30/283)vs. 6.0%(36/819), <0.001) and composite endpoint(14.1%(40/283)vs. 7.0%(57/819), <0.001). Among STEMI patients aged <60 years, no differences were found in in-hospital mortality (1.7%(1/58)vs. 1.4%(6/437)) and composite endpoint(3.6%(3/58)vs. 3.4%(15/437)) rates between female and male patients (both >0.05). Among STEMI patients aged ≥60 years, female patients had higher in-hospital mortality (12.9%(29/225)vs. 7.9%(30/382), <0.001), and there was no difference on composite endpoint between female and male patients (16.4%(37/225)vs. 11.0%(42/382), =0.054). Multivariate logistic regression analysis showed that female gender was not the independent risk factor of in-hospital death(=1.029, 95% 0.564-1.877, =0.926) and composite end point(=1.593, 95% 0.989-2.566, =0.055), but age was the independent risk factor of in-hospital death(=1.065, 95% 1.037-1.094, <0.001) and composite end point(=1.050, 95% 1.029-1.071, <0.001)in STEMI patients. Multivariate logistic regression analysis also showed that female was not the independent risk factor of in-hospital death(=1.539, 95% 0.572-4.142, =0.394) and composite end point(=1.563, 95% 0.689-3.546, =0.285), but age was the independent risk factor of in-hospital death(=1.052, 95% 1.011-1.096, =0.013) and composite end point(=1.042, 95% 1.008-1.077, =0.016)in STEMI patients received primary percutaneous coronary intervention. Female patients with STEMI have higher incidence of in-hospital major adverse cardiovascular and cerebrovascular events than male patients, and age is the independent risk factor of in-hospital major adverse cardiovascular and cerebrovascular events of STEMI patients.
