Abstract【Objective】To analyze the effect of body mass index (BMI) on the long-term prognosis of elderly patients with coronary heart disease after percutaneous coronary intervention (PCI). 【Methods】From June 2014 to December 2018, 278 patients with stable coronary heart disease aged over 60 years were selected and divided into normal weight group (BMI of 18.5-24.0 kg/m2,n=81), overweight group (BMI of 24.1-28.0 kg/m2,n=134) and obesity group (BMI>28.0 kg/m2,n=63) according to BMI. The clinical data of the patients in the admitted were collected to analyze the influence of BMI on the long-term prognosis of patients. 【Results】There were no significant differences in age, diabetes mellitus, hypertension, hyperlipidemia, white blood cell (WBC), platelet (PLT), hemoglobin (HB), high density lipoprotein cholesterol (HDL-C) and total cholesterol (TC) levels among the three groups (P<0.05). The 2-year mortality and incidence of adverse events in normal weight group were 8.64% and 32.10%, which were significantly higher than those in overweight group (2.24%, 17.16%) and obesity group (1.59% and 11.11%) (P<0.05). Logistic regression analysis showed that age≥70 years, waist circumference ≥ 90 cm, diabetes mellitus, hypertension, hyperlipidemia and normal BMI were independent risk factors for adverse events after PCI in patients with stable coronary heart disease (P<0.05). 【Conclusion】Although the elderly patients with coronary heart disease with BMI ≥ 24.0 kg/m2 have more risk factors than those with normal BMI, their long-term prognosis after PCI is better than those with normal BMI, and the risk of death is lower than that of patients with normal BMI.
