Bariatric surgery may improve left ventricular structure, function and LV strain
Bariatric surgery may improve left ventricular structure, function and strain suggests a new study published in the Journal of the American Heart Association.
Obesity leads to an increased risk of cardiovascular disease morbidity and death, including heart failure. Bariatric surgery has been proven to be the most effective long‐term weight management treatment. This study investigated the changes in cardiac structure and function after bariatric surgery, including left ventricular global longitudinal strain. 398 consecutive patients underwent bariatric surgery with pre‐ and postoperative transthoracic echocardiographic imaging at a US health system between 2004 and 2019. We compared cardiovascular risk factors and echocardiographic parameters between baseline and follow‐up at least 6 months postoperatively. Along with decreases in weight postoperatively, there were significant improvements in cardiovascular risk factors, including a reduction in systolic blood pressure levels from 132 mm Hg to 127 mm Hg, glycated haemoglobin levels from 6.5% to 5.7%, and low‐density lipoprotein levels from 97 mg/dL to 86 mg/dL. Left ventricular mass decreased from 205 g to 190 g, left ventricular ejection fraction increased from 58% to 60%, and left ventricular global longitudinal strain improved from −15.7% to −18.6% postoperatively. This study has shown the long‐term impact of bariatric surgery on cardiac structure and function, with reductions in left ventricular mass and improvement in left ventricular global longitudinal strain. These findings support the cardiovascular benefits of bariatric surgery.
