Short- and mid-term effects of sleeve gastrectomy on Left Ventricular Functions with Two-Dimensional Speckle Tracking Echocardiography in obese patients

摘要

Aim This study aimed to investigate left ventricular functions of obese patients with no known heart disease who underwent laparoscopic sleeve gastrectomy by speckle tracking echocardiography in their early and medium-term postoperative follow-up. Patients and Method Thirty-seven obese patients (10 M, 27 F) without coronary artery disease or heart failure who had undergone LSG were included in the study. Apical four-, three-, and two-chamber images were analyzed longitudinally by conventional methods and speckle tracking echocardiography (STE) for left ventricle functions preoperatively, at the postoperative Month 1 and at the postoperative Month 6 (QLAB 6.0), using current software. Results No difference was found between standard echocardiography and Doppler parameters in terms of the 1-month versus 6-month follow-up values compared to baseline. Left ventricular STE longitudinal measurements demonstrated significantly higher longitudinal strain and strain velocity parameters in the follow-up values at Month 6 compared to the values at Month 1 and at baseline. Global longitudinal strain (GLS) was -17.48 +/- 1.09% in 6-month follow-up, -16.16 +/- 1.26% in 1-month follow-up, and -16.06 +/- 1.25% at baseline (P < .001). A significant correlation was found between delta GLS, which represents patients' GLS change in 6 months, and delta weight, which represents patients' body weight change in 6 months. Conclusion Obese patients who had undergone LSG were observed to have improved left ventricular function in the mid-term.
