Abstract
Background: The association between body mass index (BMI) and the management and in-hospital outcomes of patients hospitalized for acute myocardial infarction (AMI) is unclear.
Objectives: We sought to determine the effect of BMI on the clinical presentation, management, and in-hospital outcomes of AMI patients.
Methods: This prospective cohort study included patients admitted with AMI at the Department of Cardiology, PIMS, Islamabad, between 1st March 2024 and 31st July 2024. Adult (aged ≥ 18 years) male and female patients with AMI confirmed by symptoms, electrocardiographic changes, and elevated cardiac biomarkers were included. Patients with incomplete medical records or those who left against medical advice were excluded.
Results: A total of 1,200 patients with AMI were included in this study and divided into four groups according to BMI: underweight (n=60), normal-weight (n=480), overweight (n=420), and obese (n=240). The baseline characteristics of the obese group indicated they were relatively younger than those in the other three groups (p=0.045). In multivariate logistic regression analysis, age (OR 1.05, 95% CI: 1.02-1.08, p=0.001) and obesity (OR 1.35, 95% CI 1.01-1.79, p=0.042) were significant factors.
Conclusion: These results indicate that although BMI may not affect the utilization of in-hospital treatments for AMI, it does influence the length of hospital stay and complications.
