Abstract
- Background: Obesity is associated with metabolic syndrome which increases further risk of coronary artery disease and adverse cardiovascular events. Impact of body mass index (BMI) on long‐term outcome in patients with coronary chronic total occlusion (CTO) is less clear. Method and results: From January 2005 to November 2020, a total of 1301 patients with coronary angiographic confirmed CTO were enrolled in our study. Patients were divided into two groups: low BMI group: 18–24.99 kg/m2 and high BMI group ≥25 kg/m2. Clinical outcomes were 3‐year all‐cause mortality, 3‐year cardiovascular mortality and 3‐year non‐fatal myocardial infarct. During the 3‐year follow‐up period, all‐cause mortality was significantly higher in patients with low BMI group compared to those in high BMI groups (14% vs. 6%, p =.0001). Kaplan–Meier analysis showed patients with high BMI groups had significant better survival compared with those in low BMI group (p =.0001). In multivariate analysis, higher BMI was independently associated with decreased risk of 3‐year all‐cause mortality (Hazard ratio [HR]: 0.534; 95% confidence interval [CI]: 0.349–0.819, p =.004) after controlling for age, renal function, prior history of stroke, coronary artery bypass graft, co‐morbidities with peripheral arterial disease, heart failure and revascularization status for CTO. In propensity‐matched multivariate analysis, high BMI remained a significant predictor of 3‐year all‐cause mortality (HR, 0.525; 95% CI, 0.346–0.795, p =.002). Conclusion: Higher BMI was associated with better long‐term outcome in patients with coronary CTO. [ABSTRACT FROM AUTHOR]
