Evaluation of Global Longitudinal Strain Pattern (GLS) and Echocardiographic Parameters in the Sleeve Gastrectomy Patients Before and After Surgery

Background and Objective: Obesity is one of the problems associated with cardiovascular complications. Patients' heart function improves after sleeve gastrectomy. Global Longitudinal Strain (GLS) is one of the methods used to monitor heart function before and after sleeve gastrectomy.  In this study, we evaluated the echocardiographic parameters pre and post sleeve gastrectomy. Materials and Methods: Obesity is one of the problems associated with cardiovascular complications. Patients' heart function improves after sleeve gastrectomy. Global Longitudinal Strain (GLS) is one of the methods used to monitor heart function before and after sleeve gastrectomy.  In this study, we evaluated the echocardiographic parameters pre and post sleeve gastrectomy. Results: Data analysis showed that GLS increased after surgery compared to preoperative period (15.4 ± 3.8 vs. 18.4 ± 3.04). Also, PAP, LVEDV, LVESV, LVDD, LVDS and AO were higher in the mentioned period; these findings were statistically significant (p-value <0.05). However, the RVSM mean, TAPSE, RVFAC and LVH parameters were higher post-surgery in comparison to the pre- surgery; a significant relationship was observed between the parameters before and after surgery. Conclusion: It can be concluded that GLS method, which evaluates echocardiographic parameters in obese patients undergoing sleeve gastrectomy can be highly significant in monitoring patients.
