Abstract

Background: Obesity contributes to left ventricular diastolic dysfunction (LVDD) and may lead to diastolic heart failure. Weight loss (WL) after bariatric surgery (BS) may influence LV morphology and function. Using echocardiography, this study assessed the effect of WL on LV diastolic function (LVDF) and LV and left atrium (LA) morphology 6 months after BS in young women with morbid obesity.; Methods: Echocardiography was performed in 60 women with BMI ? 40kg/m2, aged 37.1 � 9.6 years prior to and 6 months after BS. In 38 patients, well-controlled arterial hypertension was present. Heart failure, coronary artery disease, atrial fibrillation and mitral stenosis were exclusion criteria. Parameters of LV and LA morphology were obtained. To evaluate LVDF, mitral peak early (E) and atrial (A) velocities, E-deceleration time (DcT), pulmonary vein S, D and A reversal velocities were measured. Peak early diastolic mitral annular velocities (E') and E/E' were assessed.; Results: Mean WL post
