Abstract:
Objective To explore the related risk factors for bypass graft occlusion in patients within 1 year after coronary artery bypass grafting,in order to provide the basis for the prevention of postoperative bypass graft occlusion.Methods Clinical data of 197 cases treated with coronary artery bypass grafting were collected,and the incidence rate of bypass graft occlusion and its related risk factors were analyzed.Results Graft occlusion occurred in 28 (14.2％) of 197 patients.The incidence rate of bypass graft occlusion were much higher in patients with BMI ≥24 kg/m2,smoking,hypertension,hyperlipemia,diabetes,peripheral vascular diseases and cerebrovascular disease than in patients with BMI ＜24 kg/m2,non-smoking,patients without hypertension,hyperlipemia,diabetes,peripheral vascular diseases or cerebrovascular disease (20.0％ vs.9.8％,22.4％ vs.10.8％,21.2％ vs.3.8％,31.1％ vs.9.2％,23.4％ vs.9.8％,25.5％ vs.10.7％,26.3％ vs.11.3％,x2 =4.106,4.534,11.735,13.658,6.615,6.486,5.656,respectively,P=0.043,0.033,0.001,＜0.001,0.010,0.011,0.017).Smoking,diabetes,hyperlipidemia,peripheral vascular diseases and cerebrovascular disease were the independent risk factors for bypass graft occlusion.Conclusions Many risk factors are related with short-term postoperative bypass graft occlusion in patients with coronary artery bypass grafting.The corresponding control measures should be conducted to decrease the risk of postoperative bypass graft occlusion,aiming directly at the risk factors,especially the independent risk factors.
