经皮冠状动脉介入治疗术后低血压影响因素研究

Analysis of factors related to hypotension after percutaneous coronary intervention

目的探讨经皮冠状动脉介入治疗(PCI)术后低血压发生的相关因素。方法采用一般情况调查表、PCI术后低血压情况记录表收集140例PCI患者术后血压情况及相关影响因素,运用单因素分析及Logistic回归分析探索PCI术后低血压相关因素。结果140例患者中,35例发生低血压,发生率为25.0%。Logistic回归分析结果显示,PCI术后患者低血压发生的危险因素有术后血流分级和术后使用替罗非班,保护因素有胸痛到梗死相关动脉(IRA)开通时间和右冠状动脉病变(P<0.05,P<0.01)。结论PCI术后易并发低血压,其影响因素是多方面的,医护人员应有效控制危险因素,更好地防治PCI术后低血压的发生。

Objective To evaluate the factors conspiring to cause hypotension after percutaneous coronary intervention(PCI).Methods A total of 140 patients after PCI were recruited in the retrospective study,and their clinical data were collected using a general information questionnaire and from the post-PCI hypotension record book.Then univariate analysis and Logistic regression analysis were performed to explore the factors conspiring to cause hypotension after PCI.Results Post-PCI hypotension occurred in 35 cases(25.0%)out of the 140 patients.Logistic regression analysis results showed that,the risk factors were post-PCI TIMI flow grading and postoperative administration of tirofiban,while the protective factors included the time span from chest pain to recanalization of infarct-related artery(IRA),and the right coronary artery lesions(P<0.05,P<0.01).Conclusion Hypotension is a common clinical manifestation post-PCI,and its influencing factors are various.Medical staffers should effectively control the risk factors,to better prevent the occurrence of post-PCI hypotension.
