Cardiovascular disease (CVD), which encompasses atherosclerotic conditions such as coronary heart disease, cerebrovascular disease, and peripheral arterial disease, is the most common cause of death among adults in the United States. Treatment to prevent CVD events by modifying risk factors is currently informed by CVD risk assessment with tools such as the Framingham Risk Score or the Pooled Cohort Equations, which stratify individual risk to inform treatment decisions.
To update the 2012 US Preventive Services Task Force (USPSTF) recommendation on screening for coronary heart disease with electrocardiography (ECG).
The USPSTF reviewed the evidence on whether screening with resting or exercise ECG improves health outcomes compared with the use of traditional CVD risk assessment alone in asymptomatic adults.
For asymptomatic adults at low risk of CVD events (individuals with a 10-year CVD event risk less than 10%), it is very unlikely that the information from resting or exercise ECG (beyond that obtained with conventional CVD risk factors) will result in a change in the patient's risk category as assessed by the Framingham Risk Score or Pooled Cohort Equations that would lead to a change in treatment and ultimately improve health outcomes. Possible harms are associated with screening with resting or exercise ECG, specifically the potential adverse effects of subsequent invasive testing. For asymptomatic adults at intermediate or high risk of CVD events, there is insufficient evidence to determine the extent to which information from resting or exercise ECG adds to current CVD risk assessment models and whether information from the ECG results in a change in risk management and ultimately reduces CVD events. As with low-risk adults, possible harms are associated with screening with resting or exercise ECG in asymptomatic adults at intermediate or high risk of CVD events.
The USPSTF recommends against screening with resting or exercise ECG to prevent CVD events in asymptomatic adults at low risk of CVD events. (D recommendation) The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening with resting or exercise ECG to prevent CVD events in asymptomatic adults at intermediate or high risk of CVD events.

心血管疾病(CVD)包括动脉粥样硬化疾病,如冠心病、脑血管疾病和外周动脉疾病,是美国成年人中最常见的死亡原因。通过改变风险因素来预防 CVD 事件的治疗方法目前是通过 CVD 风险评估来指导,例如Framingham 风险评分或 Pooled Cohort Equations,这些工具可对个体风险进行分层,以辅助治疗决策。
更新 2012 年美国预防服务工作组(USPSTF)关于使用心电图(ECG)筛查冠心病的建议。
USPSTF 审查了在无症状成年人中,与单独使用传统 CVD 风险评估相比,使用静息或运动 ECG 筛查是否能改善健康结果的证据。
对于 CVD 事件风险较低(Framingham 风险评分或 Pooled Cohort Equations 评估 10 年内 CVD 事件风险<10%)的无症状成年人,静息或运动 ECG (超出常规 CVD 风险因素获得的信息)提供的信息不太可能改变患者的风险类别,这可能导致治疗方式的改变,并最终改善健康结果。静息或运动 ECG 筛查可能存在危害,具体包括随后进行侵入性检查的潜在不良反应。对于 CVD 事件风险处于中高危的无症状成年人,目前尚无足够的证据来确定静息或运动 ECG 的信息在多大程度上增加了当前的 CVD 风险评估模型,以及 ECG 结果是否导致了风险管理的改变,并最终降低了 CVD 事件的发生。与低危成年人一样,静息或运动 ECG 筛查可能会对 CVD 事件中高危的无症状成年人产生危害。
USPSTF 建议不对 CVD 事件风险较低的无症状成年人进行静息或运动 ECG 筛查,以预防 CVD 事件。(D 级推荐)USPSTF 得出结论,目前的证据不足以评估静息或运动 ECG 筛查以预防 CVD 事件的利弊平衡,在 CVD 事件中高危的无症状成年人。(I 声明)。
