Effect of sex on reperfusion time delay in ST-segment elevation myocardial infarction patients after diagnosis / 中华老年心脑血管病杂志

ABSTRACT

Objective To study the effect of sex on reperfusion time delay in ST-segment elevation myocardial infarction (STEMI) patients after diagnosis.Methods A total of 1647 STEMI patients admitted to our hospital were included in this study.Their clinical data and treatment time points were recorded.The reperfusion time delay after diagnosis refers the time from ECG-based diagnosis to PCI.The reperfusion time delay after diagnosis was divided into 0-3 h,＞3-6 h,＞6-12 h,＞12-24 h and ＞24 h.The effect of sex and other risk factors on reperfusion time delay after diagnosis was assessed according to the established logistic regression model.Results The age of female STEMI patients was older than that of male STEMI patients (65±10 years vs 60±11 years,P＜0.05).The rate of past CABG and PCI was significantly higher and the reperfusion time delay was significantly longer in female STEMI patients than in male STEMI patients (4.3 ％ vs 1.5％,20.7％ vs 17.4％,P＜0.05;404±34 min vs 280±14 min,P＜0.01).Multivariate logistic regression analysis showed that female and visiting form were related with the reperfusion time delay for ＞3-6 h and ＞12-24 h (95％CI1.052-264.306,P=0.046;95％CI1.089-2.751,P=0.013).Conclusion Female is related with reperfusion time delay,visiting form and call for emergency treatment in STEMI patients.
