Objectives: The aim of current study is to evaluate relation between body mass index (BMI) and in-hospital outcome in patients undergoing percutaneous coronary intervention (PCI). Background: Relation between body mass indexes (BMI) with percutaneous coronary intervention (PCI) has shown in different studies. Recent studies suggested a paradox relation between different BMI values and outcome in certain patients. Methods: In this prospective study, 1134 patients (81.7% male, 18.3% female with mean age of58.18±11.16 years) whom undergone PCI between January 2011 and December 2011 were chosen and their BMI and disease outcome was studied. Classification of BMI was: healthy weight (18.5 to24.9 kg/m2), overweight (25 to 29.9 kg/m2), moderate obesity (30 to 34.9 kg/m2) and severe obesity (over 35 kg/m2). Baseline patient characteristics and in-hospital outcome were compared among BMI categories. Results: Major adverse cardiac events (MACE) were significantly higher in patients with overweight and moderate obesity than two other groups. There was no difference in mortality, reinfarction, revascularisation, stroke and bleeding events among the 4 groups. Being overweight is an independent factor associated to in-hospital MACE (odds ratio [OR] 0.37, 95% confidence interval [CI] 0.17 to 0.73, p=0.01) and mortality rate (OR 0.20, 95%CI 0.04 to 0.85, p=0.03). Conclusion: BMI overall is not correlated to in-hospital MACE and mortality; however, overweight patients are at reduced risk for MACE and mortality.
