Body mass index and coronary revascularization in women with coronary artery disease: insight into obesity paradox

Abstract

ObjectiveTo determine the association between body mass index and indication of angioplasty with stent implantation in women over 50 years of age. Material and methodsRetrospective analytical study, cross-sectional. It were evaluated 83 clinical records of women older than 50 years of age who underwent angiography due to coronary artery disease and were hospitalized in Peruvian Naval Medical Center between 2010 and 2017. A Poisson regression analysis was performed to determine the association. ResultsThe mean±standard deviation of age was 66.51±8.94 years. 81.93% had two or more comorbidities. The frequency of angioplasties with stent implantation was 58%. Body mass index in range of obesity (45.83%) was more frequent in patients who received the implant. In the adjusted regression model, overweight patients had lower probability (PR 0.83, 95% CI 0.68 – 0.98) to have the indication of implantation as compared to patients with body mass index less than 25kg/m2. ConclusionsAlthough obesity paradox relationship between body mass index and angioplasty with stent indication has been demonstrated by the multivariate analysis of this study, it is necessary to evaluate obesity with better markers than body mass index before assuming that obesity is a good prognostic factor for coronary artery disease in our patient.
