BACKGROUND
Comparative evidence is needed when deciding which bariatric operation to undergo for long-term cardiovascular risk reduction.
OBJECTIVES
The Effectiveness of Gastric Bypass vs. Gastric Sleeve for Cardiovascular Disease (ENGAGE CVD) study compared the effectiveness of vertical sleeve gastrectomy (VSG) and Roux-en-Y gastric bypass (RYGB) operations for reduction of the American College of Cardiology and the American Heart Association-predicted 10-year atherosclerotic cardiovascular disease (ASCVD) risk 5 years after surgery.
SETTING
Data for this study came from a large integrated healthcare system in the Southern California region of the United States. This is one of the most ethnically diverse (64% non-White) bariatric populations in the literature.
METHODS
The ENGAGE CVD cohort consisted of 22,095 patients who underwent VSG or RYGB from 2009-2016. The VSG and RYGB were compared using a local instrumental variable approach to address observed and unobserved confounding, as well as to conduct heterogeneity of treatment effects for patients of different age groups, baseline-predicted 10-year CVD risk using the ASCVD risk score, and those who had type 2 diabetes (T2D) at the time of surgery.
RESULTS
Patients (2771 RYGB and 6256 VVSG) were primarily women (80.6%), Hispanic or non-Hispanic Black (63.7%), and 46 ± 10 years of age, with a body mass index of 43.40 ± 6.5 kg/m. The predicted 10-year ASCVD risk at surgery was 4.1% for VSG and 5.1% for RYGB, decreasing to 2.6% for VSG and 2.8% for RYGB 1 year postoperatively. By 5 years after surgery, patients remained with relatively low risk levels (3.0% for VSG and 3.3% for RYGB) and there were no significant differences in predicted 10-year ASCVD risk between VSG and RYGB at any time.
CONCLUSION
Predicted 10-year ASCVD risk was low in this population and remained low up to 5 years for those with diabetes, Black and Hispanic patients, and older adults. Literature reporting significant differences between VSG and RYGB in 10-year ASCVD risk may be a result of residual confounding.
背景
在决定进行哪种减重手术以降低长期心血管风险时，需要进行比较性证据评估。
目的
《胃旁路术与胃袖状切除术治疗心血管疾病的效果比较（ENGAGE CVD）》研究比较了垂直袖状胃切除术（VSG）和 Roux-en-Y 胃旁路术（RYGB）在术后 5 年内降低美国心脏病学会和美国心脏协会预测的 10 年动脉粥样硬化性心血管疾病（ASCVD）风险的效果。
设置
本研究的数据来自美国南加州地区一个大型综合医疗保健系统。这是文献中种族最多样化的（64%为非白人）减重人群之一。
方法
ENGAGE CVD 队列由 2009 年至 2016 年期间接受 VSG 或 RYGB 的 22095 名患者组成。使用局部工具变量方法比较了 VSG 和 RYGB，以解决观察到和未观察到的混杂因素，并对不同年龄组患者的治疗效果异质性、使用 ASCVD 风险评分预测的基线 10 年 CVD 风险以及手术时患有 2 型糖尿病（T2D）的患者进行分析。
结果
患者（2771 例 RYGB 和 6256 例 VSG）主要为女性（80.6%）、西班牙裔或非西班牙裔黑人（63.7%），年龄 46±10 岁，体重指数为 43.40±6.5kg/m²。VSG 的手术时预测 10 年 ASCVD 风险为 4.1%，RYGB 为 5.1%，术后 1 年降至 VSG 为 2.6%，RYGB 为 2.8%。术后 5 年，患者的风险水平仍然相对较低（VSG 为 3.0%，RYGB 为 3.3%），且 VSG 和 RYGB 之间在任何时间点的预测 10 年 ASCVD 风险均无显著差异。
结论
在该人群中，预测的 10 年 ASCVD 风险较低，对于糖尿病患者、黑人和西班牙裔患者以及老年人，该风险在 5 年内仍保持较低水平。文献报道 VSG 和 RYGB 在 10 年 ASCVD 风险方面存在显著差异，可能是由于残余混杂因素所致。
