Cardiovascular disease (CVD) is the leading cause of death in the United States and many parts of the world. Potentially modifiable risk factors for CVD include tobacco use, physical inactivity, hypertension, elevated low-density lipoprotein cholesterol, and a cluster of interrelated metabolic risk factors. Over the last several decades, efforts to prevent or treat CVD risk factors have resulted in significantly lower rates of CVD-related mortality. However, many patients never achieve adequate control of CVD risk factors even when these factors have been identified. In addition, the growing prevalence of obesity and type 2 diabetes mellitus (DM) threatens to undermine the improvements in CVD that have been achieved. In the United States, approximately two thirds of adults are overweight or obese, and even modest excess body weight is associated with a significantly increased risk of CVD-related mortality. Lifestyle interventions to promote weight loss reduce the risk of CVD-related illness but are difficult for patients to sustain over long periods of time. The increased incidence of obesity has also contributed to significant increases in the prevalence of other important CVD risk factors, including hypertension, dyslipidemia, insulin resistance, and type 2 DM. Pharmacologic therapies are currently available to address individual CVD risk factors, and others are being evaluated, including endocannabinoid receptor antagonists, inhibitors of peroxisome proliferator-activated receptor subtypes alpha and gamma, and several agents that modulate the activity of glucagon-like peptide-1. The new agents have the potential to significantly improve several CVD risk factors with a single medication and may provide clinicians with several new strategies to reduce the long-term risk of CVD.
心血管疾病(CVD)是美国及世界许多地区的主要死因。CVD潜在的可改变风险因素包括吸烟、缺乏运动、高血压、低密度脂蛋白胆固醇升高以及一系列相互关联的代谢风险因素。在过去几十年中,预防或治疗CVD风险因素的努力已使CVD相关死亡率显著降低。然而,即使已识别出这些风险因素,许多患者仍无法充分控制CVD风险因素。此外,肥胖症和2型糖尿病(DM)患病率的不断上升,有可能破坏已取得的CVD防治成果。在美国,约三分之二的成年人超重或肥胖,即使是适度超重也与CVD相关死亡率显著增加有关。促进体重减轻的生活方式干预可降低CVD相关疾病的风险,但患者很难长期坚持。肥胖症发病率的上升还导致了其他重要CVD风险因素患病率的显著增加,包括高血压、血脂异常、胰岛素抵抗和2型DM。目前已有药物疗法可针对个体CVD风险因素进行治疗,其他疗法正在评估中,包括内源性大麻素受体拮抗剂、过氧化物酶体增殖物激活受体亚型α和γ的抑制剂,以及几种调节胰高血糖素样肽-1活性的药物。这些新药有可能通过单一药物显著改善多种CVD风险因素,并可能为临床医生提供多种新策略以降低CVD的长期风险。
