Comment on: Bariatric surgery decreases the number of hospital admissions for diastolic heart failure in subjects with severe obesity. Retrospective analysis of the US National Inpatient Sample database.

Abstract

I congratulate the authors on the study “Bariatric Surgery Decreases the Number of Hospital Admissions for diastolic Heart Failure in Subjects with Severe Obesity. Retrospective Analysis of the US National Inpatient Sample Database,” which is related to documenting the effect of bariatric surgery on cardiac failure [1]. They looked at 296,041 bariatric surgical patients and 2,004,804 severely obese controls extracted from the US National Inpatient Sample (NIS) database for the years 2010–2015. Results showed that cardiovascular disease risk factors were less common among bariatric surgery patients after surgery, while the controls exhibited marked increases in the odds of diastolic heart failure overall (odds ratio [OR] = 2.80).
