Abstrakt: Background: Obesity is a well-known risk factor for cardiovascular diseases. The aim of this study was to prospectively investigate the short-term effects of laparoscopic sleeve gastrectomy (LSG) on cardiac functions.
Methods: Forty-four morbidly obese patients who underwent LSG were included in the study. The aortic systolic and diastolic diameters, left ventricular (LV) diameter, LV cardiac output and cardiac index, LV ejection fraction, LV septal and lateral wall velocities, deceleration time of the E wave, the LA volume index and atrial mechanic functions, and atrial conduction times were evaluated.
Results: The patients' aortic stiffness index showed a significant improvement at postoperative control: 3.23 ± 0.58, 2.49 ± 0.36; p<0.001 for preoperative and postoperative aortic stiffness index, respectively. A significant reduction was observed in the LV mass and relative wall thickness (RWT) of the patients: 182.41 ± 36.87 g, 154.85 ± 24.32 g; p<0.001 and 0.42 ± 0.07, 0.39 ± 0.05; p=0.010 for the preoperative and postoperative LV mass and RWT, respectively. A statistically significant decrease was observed in total atrial conduction time and interatrial and intraatrial conduction time in the postoperative period: 120.95 ± 22.27 ms, 106.57 ± 20.46 ms; p=0.001; 13.82 ± 8.21 ms, 10.66 ± 6.78 ms; p=0.038, and 29.64 ± 14.18 ms, 24.09 ± 10.95 ms; p=0.047 for preoperative and postoperative total atrial conduction time, intraatrial electromechanical delay, and interatrial electromechanical delay, respectively.
Conclusions: Weight loss reduced aortic stiffness, IVS and posterior wall thickness, LAV, LAVi, LA passive emptying fraction, and atrial electromechanical delays in morbidly obese patients.
