The Early Effects of Bariatric Surgery on Cardiac Structure and Function: a Systematic Review and Meta-Analysis
Background This meta-analysis was performed to investigate how cardiac structures and functions change in the very early stage after bariatric surgery. Materials and Methods We thoroughly searched the PubMed, Embase, Cochrane Library, and Web of Science databases for articles including patients who underwent bariatric surgery and examined the changes of their cardiac indices. Results were pooled by using Review Manager 5.1 and Stata 12.0. Weighted mean differences (WMDs) with 95% confidence intervals (CIs) were obtained. The I-squared (I2) test was used to determine the heterogeneity between studies. To identify publication bias, funnel plots and Egger’s test were utilized. The leave-one-out method was used to conduct sensitivity analysis. Results In this meta-analysis, 24 research including 942 patients were considered. According to our findings, most cardiac indices changed 3–6 months following bariatric surgery. An improvement in cardiac geometry was reflected by a reduction in left ventricular mass (LVM) (WMD = − 22.06, 95% CI = (− 27.97, − 16.16)). The left ventricular diastolic function improved, as reflected by the decrease in the E/e’ ratio (WMD = − 0.90, 95% CI = (− 1.83, − 0.16)). Left ventricular ejection fraction (LVEF) did not show an obvious change (WMD = 0.94, 95% CI = (− 0.19, 2.07)), while a more sensitive indicator of left ventricular systolic function, left ventricular longitudinal strain (LV LS), increased (WMD = − 2.43, 95% CI = (− 3.96, − 0.89)). Conclusion This meta-analysis includes the newest and most comprehensive cardiac indices to prove that cardiac structures and functions are improved early after bariatric surgery, which has not been reported by any other studies.
