USPSTF: No to ECG screening to prevent CVD in low-risk adults
To inform the USPSTF, Daniel E. Jonas, M.D., M.P.H., from the University of North Carolina at Chapel Hill Evidence-Based Practice Center, and colleagues conducted a systematic review of the evidence from 16 studies with 77,140 participants on screening asymptomatic adults for CVD risk using ECG.
The researchers found that it is very unlikely that the information from resting or exercise ECG would result in a change in a patient's risk category that would lead to a change in treatment or improve health outcomes for asymptomatic adults at low risk for CVD events. Screening with resting or exercise ECG is associated with possible harms, specifically the potential adverse effects of subsequent invasive testing. Based on these findings, the USPSTF recommends against resting or exercise ECG to prevent CVD events in asymptomatic adults (D recommendation). For asymptomatic adults at intermediate or high risk of CVD events, the evidence is insufficient to assess the balance of benefits and harms of screening.
"There is not enough evidence for those who might benefit the most—people at higher risk for CVD—to say if adding ECG screening helps prevent heart attack and stroke," Task Force member Michael J. Barry, M.D., said in a statement. "Clinicians should continue to use traditional risk factors to assess CVD risk and guide treatment for these patients until more evidence is available."
