Obesity is a global epidemic affecting 2.5 billion people and is recognized as the fourth leading cause of global mortality. Obesity is characterized by excessive accumulation of body fat and is associated with a range of health consequences, including an elevated risk of cardiovascular disease (CVD). Glucagon-like peptide-1 (GLP-1) receptor agonists have been proven to reduce cardiovascular outcomes in patients with diabetes. Study and results: The SELECT trial was a multicenter, double-blind, randomized, placebo-controlled, event-driven superiority trial, conducted at 804 clinical sites in 41 countries. Patients were randomly assigned in a 1:1 ratio, to receive once-weekly subcutaneous semaglutide at a dose of 2.4 mg or placebo. The primary cardiovascular efficacy endpoint was a composite of death from cardiovascular causes, nonfatal myocardial infarction, or nonfatal stroke, assessed in a time-to-first-event analysis. A total of 17,604 patients were recruited, with a mean age of 61.6 years and 72.3% males. The mean duration of exposure to semaglutide or placebo in the overall trial population was 34.2 ± 13.7 months. The primary CVD endpoint occurred in 6.5% ( = 569) of the semaglutide group and 8% ( = 701) in the placebo group (hazard ratio, 0.80; 95% CI, 0.72 to 0.90; < 0.001). There was also a significant reduction of 9.39% in body weight among the patients taking semaglutide over 104 weeks after randomization versus 0.88% among the placebo group.
Semaglutide reduces the incidence of death from cardiovascular causes, nonfatal myocardial infarction, or nonfatal stroke in obese and overweight non-diabetic patients with preexisting cardiovascular disease.
肥胖是一种全球流行病,影响着25亿人,被认为是全球第四大主要死因。肥胖的特征是身体脂肪过度堆积,并与一系列健康后果相关,包括心血管疾病(CVD)风险升高。胰高血糖素样肽-1(GLP-1)受体激动剂已被证明可降低糖尿病患者的心血管事件发生率。研究与结果:SELECT试验是一项多中心、双盲、随机、安慰剂对照、事件驱动的优效性试验,在41个国家的804个临床地点进行。患者以1:1的比例随机分配,接受每周一次皮下注射2.4毫克司美格鲁肽或安慰剂。主要心血管疗效终点是心血管原因死亡、非致命性心肌梗死或非致命性中风的复合终点,采用首次事件时间分析进行评估。共招募了17604名患者,平均年龄61.6岁,男性占72.3%。在整个试验人群中,司美格鲁肽或安慰剂的平均暴露时间为34.2±13.7个月。主要CVD终点在司美格鲁肽组的发生率为6.5%(n = 569),在安慰剂组为8%(n = 701)(风险比,0.80;95%置信区间,0.72至0.90;P < 0.001)。随机分组后104周内,服用司美格鲁肽的患者体重也显著降低了9.39%,而安慰剂组为0.88%。
司美格鲁肽可降低患有心血管疾病的肥胖和超重非糖尿病患者心血管原因死亡、非致命性心肌梗死或非致命性中风的发生率。
