冠心病老年患者PCI术后冠状动脉血流和支架内再狭窄的危险因素分析

Risk Factors Analysis of Coronary Blood Flow and Stent Restenosis in Elderly Patients with Coronary Heart Disease after PCI

目的分析冠心病老年患者PCI术后冠状动脉血流和支架内再狭窄的危险因素。方法纳入研究的90例接受PCI手术治疗的冠心病老年患者根据患者术后是否会发生支架内再狭窄分为再狭窄组(n=27)和非再狭窄组(n=63)。判定冠状动脉血流分级情况,并通过单因素和Logistic回归分析支架内再狭窄的危险因素。结果支架内再狭窄危险因素的单因素分析,危险因素与年龄、吸烟状况、酗酒状况、FBG、TC、FIB和LDL-C水平有关(P<0.05),危险因素与性别、身高、体重和病程无关(P>0.05)。通过Logistic回归分析结果显示,FBG、TC、FIB、LDL-C是支架内再狭窄的危险因素(P<0.05)。结论冠心病老年患者PCI术后冠状动脉血流和支架内再狭窄与FBG、TC、FIB、LDL-C水平有关。

Objective To analyze the risk factors of coronary blood flow and in-stent restenosis in elderly patients with coronary heart disease after PCI.Methods Ninety elderly patients with coronary heart disease who underwent PCI were included in the study and divided into the restenosis group(n=27)and the non-restenosis group(n=63)according to the incidence of in-stent restenosis.Coronary blood flow grading was determined,and risk factors for in-stent restenosis were analyzed by univariate and Logistic regression.Results Univariate analysis of the risk factors for in-stent restenosis showed that the risk factors were related to age,smoking status,alcoholism status,FBG,TC,FIB and LDL-C levels(P<0.05),while the risk factors were not related to sex,height,weight and course of disease(P>0.05).Logistic regression analysis showed that FBG,TC,FIB and LDL-C were risk factors for in-stent restenosis(P<0.05).Conclusions Coronary blood flow and stent restenosis in elderly patients with coronary heart disease after PCI are related to the levels of FBG,TC,FIB and LDL-C.
