Abstract:
Objective To investigate the influence of body mass index(BMI) on the prognosis of patients who had received elective PCI.Methods The study population consisted of 2964 consecutive patients with electivePCIs performed between July 2009 and September 2011. The patients were divided into three groups based on their preoperative BMI levels:the normal group( BMI<24.0 kg/m2,n=810); the overweight group( 24.0 kg/m2≤BMI<28.0 kg/m2,n=1454) and the obese group(BMI≥28.0 kg/m2,n=700). We examined the association between baseline BMI levels and postoperative mortality through a mean(571.5±130.8)days of follow up.Results Patients with high BMI had a higher percentage of comorbidities compared with the normal BMI group. The results of multivariate Cox regression analysis revealed that preoperative BMI was inversely associated with mortality after adjustment for other factors (HR 0.896,95％ CI 0.821-0.977,P=0.031). Compared with the obese group, the hazard ratios for risk of mortality in the overweight and the normal groups were 1.908(95％CI 0.689-5.291,P=0.213) and 2.241(95％CI 1.154-4.350,P=0.017).Conclusions For patients undergoing elective PCI, individuals with obesity and overweight had the better prognosis than those with normal BMI.
