Bariatric surgery may have an effect on myocardial mechanics in individuals with obesity and diabetes. In this study, two-dimensional speckle-tracking echocardiography was applied to evaluate the changes of left ventricular myocardial mechanics in individuals with obesity and diabetes before and after bariatric surgery. A total of 58 individuals with obesity were divided into an obesity-only group (30 patients) and an obesity + diabetes group (28 patients). Routine echocardiographic parameters and left ventricular global longitudinal strain (GLS) were compared between the two groups at baseline and 6 and 12 months postoperatively. At all three time points, GLS was lower in the obesity + diabetes group than in the obesity-only group. In both groups, the GLS increased successively at 6 and 12 months postoperatively. The change in GLS (∆GLS) from baseline to 6 months was higher than the △GLS from 6 to 12 months in both groups. The △GLS from baseline to 6 months was lower in the obesity + diabetes group than in the obesity-only group. Therefore, obese individuals can benefit from bariatric surgery, which includes improved heart function, delayed disease progression.
减肥手术可能会对肥胖和糖尿病患者的心肌力学产生影响。在本研究中，应用二维斑点追踪超声心动图来评估减肥手术前后肥胖和糖尿病患者左心室心肌力学的变化。共有58名肥胖患者被分为单纯肥胖组（30例患者）和肥胖 + 糖尿病组（28例患者）。在基线、术后6个月和12个月时比较两组的常规超声心动图参数和左心室整体纵向应变（GLS）。在所有三个时间点，肥胖 + 糖尿病组的GLS均低于单纯肥胖组。在两组中，术后6个月和12个月时GLS均相继增加。两组从基线到6个月的GLS变化（∆GLS）高于从6到12个月的∆GLS。肥胖 + 糖尿病组从基线到6个月的∆GLS低于单纯肥胖组。因此，肥胖个体可从减肥手术中获益，包括改善心脏功能、延缓疾病进展。
