急性心肌梗死患者PCI术后并发低血压和心律失常的危险因素

Risk factors of hypotension and arrhythmia after PCI in patients with acute myocardial infarction

目的:探讨急性心肌梗死患者经皮冠脉介入治疗(PCI)术后并发低血压和心律失常危险因素。方法:行PCI的116例患者,根据术后是否并发低血压分为:低血压组(48例)和非低血压组(68例);是否并发心律失常分为:心律失常组(46例)和非心律失常组(70例)。比较各组基本资料,并分析急性心肌梗死患者PCI术后并发低血压或心律失常的危险因素。结果:与非低血压组比较,低血压组年龄、人体质量指数(BMI)、低血压病史、吸烟和饮酒比例均显著增加(P<0.05或<0.01);与非心律失常组比较,心律失常组年龄,BMI、心律失常病史、吸烟和饮酒比例均显著增加(P均<0.01)。对以上相关因素进行Logistic多因素分析,结果显示,急性心肌梗死PCI术后并发低血压的独立危险因素为年龄、BMI和低血压病史(OR=1.106~8.107,P<0.05或<0.01);并发心律失常的独立危险因素为年龄、BMI和心律失常病史(OR=1.106~11.452,P<0.05或<0.01)。结论:年龄、人体质量指数、低血压或心律失常病史是急性心肌梗死患者PCI术后合并低血压或心律失常的独立危险因素,对有这些危险因素的患者,应密切关注其血压及心律变化,进行相应的防治。

Objective:To explore risk factors of hypotension and arrhythmia after percutaneous coronary intervention(PCI)in patients with acute myocardial infarction(AMI).Methods:According to complicated hypotension or not after PCI,a total of 116 patients were divided into hypotension group(n=48)and non-hypotension group(n=68);according to complicated arrhythmia or not,they were divided into arrhythmia group(n=46)and non-arrhythmia group(n=70).Baseline data were compared among above groups,and risk factors of complicated hypotension or arrhythmia after PCI in AMI patients were analyzed.Results:Compared with non-hypotension group,there were significant rise in age,body mass index(BMI),percentages of hypotension history,smoking and drinking in hypotension group,P<0.05 or<0.01;compared with non-arrhythmia group,there were significant rise in age,BMI,percentages of arrhythmia,smoking and drinking in arrhythmia group,P<0.01 all.Multivariate Logistic regression analysis indicated that age,BMI and hypotension history were independent risk factors for AMI patients complicated hypotension after PCI(OR=1.106~8.107,P<0.05 or<0.01);age,BMI and arrhythmia history were independent risk factors for AMI patients complicated arrhythmia after PCI(OR=1.106~11.452,P<0.05 or<0.01).Conclusion:Age,BMI,hypotension/arrhythmia history are independent risk factors for complicated hypotension/arrhythmia after PCI in AMI patients.For these patients with risk factors,intensive attention should be paid to their blood pressure or heart rhythm changes in order to carry out corresponding prevention and care.
