The aim of this study was to examine echocardiographic parameters of left ventricle (LV) mechanics in obese patients before and after sleeve gastrectomy (SG).
Twenty-five obese individuals submitted to laparoscopic SG were enrolled in this study. Echocardiography was performed before and after the procedure, and left ventricle mechanics were evaluated by speckle tracking imaging.
Before surgery, altered global longitudinal strain (GLS) values were present in 56% of the patients. In a mean follow-up of 3.6 ± 0.5 months after surgery, there was an increase in GLS values (from 17.4 ± 3.2 to 19.3 ± 2.7%, P = 0.01). There was an inverse correlation between the absolute values of GLS in the preoperative period and the variation in the GLS at follow-up (r = 0.577, P = 0.002). Measurements of global circumferential strain (GCS), global radial strain (GRS), and LV twist were normal preoperatively and did not change after surgery.
Altered global longitudinal strain values were common in young obese patients. Sleeve gastrectomy increased global longitudinal strain even in the early postoperative phase without promoting changes in global radial strain, global circumferential strain, and left ventricle twist measurements.
本研究旨在探讨肥胖患者行袖状胃切除术（SG）前后左心室（LV）力学的超声心动图参数。
本研究纳入了 25 名接受腹腔镜 SG 的肥胖患者。在手术前后进行超声心动图检查，并通过斑点追踪成像评估左心室力学。
术前，56%的患者存在整体纵向应变（GLS）值改变。术后平均随访 3.6±0.5 个月，GLS 值增加（从 17.4±3.2 增加至 19.3±2.7%，P=0.01）。术前 GLS 的绝对值与随访时 GLS 的变化呈负相关（r=0.577，P=0.002）。术前的整体圆周应变（GCS）、整体径向应变（GRS）和 LV 扭转测量值正常，术后无变化。
年轻肥胖患者的整体纵向应变值改变常见。袖状胃切除术可增加整体纵向应变，即使在术后早期也不会引起整体径向应变、整体圆周应变和 LV 扭转测量值的变化。
