Influence of Body Mass Index on the Management and Outcomes of Acute Myocardial Infarction-Cardiogenic Shock in the United States, 2008–2017

BACKGROUND There are limited data on influence of body mass index (BMI) on outcomes of acute myocardial infarction-cardiogenic shock (AMI-CS). METHODS Adult AMI-CS admissions from 2008 to 2017 were identified from the National Inpatient Sample and stratified by BMI into underweight ( 24.9 kg/m2). Outcomes of interest included in-hospital mortality, invasive cardiac procedures use, hospitalization costs, and discharge disposition. RESULTS Of 339,364 AMI-CS admissions, underweight and overweight/obese constitute 2356 (0.7%) and 46,675 (13.8%), respectively. In 2017, compared to 2008, there was an increase in underweight (adjusted odds ratio [aOR] 6.40 [95% confidence interval {CI} 4.91-8.31]; p
