ABSTRACT
Objective To determine the risk factors for perioperative cardiovascular events (PCEs) in patients with diabetes mellitus undergoing noncardiac surgery.Methods From June 2011 to October 2012 in our hospital,500 diabetic patients scheduled for elective non-cardiac surgery were divided into 2 groups according to the development of PCEs:PCE group and non-PCE group.The general data of patients,anesthetic methods,anesthesia time,blood glucose level during surgery and fluctuation of hemodynamics were recorded.The risk factors of which P values were less than 0.05 would enter the binary logistic regression analysis to stratify PCE-related risk factors.Results Seventy-nine patients developed PCEs (15.8 ％) during perioperative period.There was significant difference between the two groups in age,levels of triglyceride and hs-CRP,fluctuation of hemodynamics,and abnormality in ECG (P ＜ 0.05).Logistic regression analysis showed that the risk factors for PCEs included triglyceride level ≥ 1.7 mmol/L,age ≥ 65yr,hs-CRP level ≥ 8 mg/L and fluctuation of hemodynamics during surgery ≥ 30％ of the baseline value.Conclusion High triglyceride levels,advanced age,high hs-CRP levels and fluctuation of hemodynamics during surgery (≥ 30％ of the baseline value) are the risk factors for PCE in diabetic patients undergoing noncardiac surgery.
