The effects of weight loss after sleeve gastrectomy on left ventricular systolic function in men versus women.

Purpose: To evaluate and compare the effects of weight lost after sleeve gastrectomy on left ventricular (LV) systolic function using both two-dimensional speckle tracking (2D-STE) and three-dimensional echocardiography (3DE) in men versus women.

Methods: In 53 obese patients referred for sleeve gastrectomy, 2D-STE and 3DE were performed prior to and 6 months after surgery.

Results: The study included 53 obese patients (62.3% female; mean age 36.8 ± 10.7 years). Six months after surgery, all patients demonstrated a significant decrease in body mass index, body weight, blood pressure, heart rate, LV end-diastolic dimension, myocardial wall thickness, LV mass, LV mass index, LV mass/height(2.7) , LV end-diastolic volume, LV end-systolic volume, and stroke volume as well as an increase in SV index and ejection fraction. There was no significant difference in measured variables between men and women at baseline or postsurgery, except for baseline LV end-diastolic dimension, and baseline and after surgery LV mass, LV mass index, and LV mass/height(2.7) , which were all significantly higher in men.

Conclusions: Sleeve gastrectomy improves LV systolic function and contributes to reverse LV remodeling in both genders. © 2016 Wiley Periodicals, Inc. J Clin Ultrasound 44:492-499, 2016.
