Bariatric Surgery and HF Exacerbation: Rate of HF Exacerbation Before and After Bariatric Surgery in a 6-Month Interval
Obesity has been linked to HF exacerbations; however, it is unknown whether substantial weight loss lowers the rate of HF exacerbations. The present study analyzed 524 patients to investigate whether bariatric surgery is associated with decreased rate of HF exacerbation. This graph shows the proportion of patients who had an ED visit or hospitalization for HF exacerbation before and after surgery. The rate declined significantly after bariatric surgery in 2 years. This study provides the best evidence on the effectiveness of bariatric surgery on HF morbidity, and will prompt further investigation into the underlying mechanisms and optimal weight management strategies for obese patients with HF. ED = emergency department; HF = heart failure.
