Influence of body mass index on outcome in patients undergoing percutaneous coronary intervention during twenty four hours of hospital stay.
J Cardiovascular Dis Jan ;16(3):117-21.

BACKGROUND: The influence of obesity on the outcome of coronary interventions is unclear. In different studies obesity paradox has been shown. The study was design to see the frequency of complications after coronary interventional procedure among patients with different body mass index during first day of post procedure hospital stay. MATERIAL AND METHODS: Three hundred and thirty five patients who underwent percutaneous coronary intervention (PCI) were enrolled. The height and weight of enrolled subjects were measured. The patients were then grouped into three groups according to body mass index (BMI). In Group A the patients were having BMI of less than 24.9, Group B included patients with BMI between 25-30, while in Group C the patients were having BMI of more than 30. The patients remained admitted for 24 hours after PCI and were monitored for major bleeding, myocardial infarction and mortality. RESULTS: Group A included 72 patients while Group B had 141 patients and in Group C there were 122 patients. Bleeding complications including gum bleed, hematoma at puncture site and anginal symptoms were comparable in all the three groups. Two patients presented with acute stent thrombosis; one each in group A (1.4%) and group B (0.7%). Mortality occurred in 2 patients; one each in group A (1.4%) and group C (0.8%). These observations showed no statistical importance. CONCLUSION: Obese, overweight and normal weight patients undergoing percutaneous coronary intervention usually have similar outcomes during hospital stay with non-significant increase in complications in normal weight individuals.
