Shah AJ, Vaccarino V, Janssens AC, Flanders WD, Kundu S, Veledar E, Wilson PW, Soliman EZ. An Electrocardiogram-Based Risk Equation for Incident Cardiovascular Disease From the National Health and Nutrition Examination Survey. JAMA cardiology. 2016 Oct 1;1(1). 779-786. PMID: 27487404 [PubMed]
Electrocardiography (ECG) may detect subclinical cardiovascular disease (CVD) in asymptomatic individuals, but its role in assessing adverse events beyond traditional risk factors is not clear. Interval and vector data that are commonly available on modern ECGs may offer independent prognostic information that improves risk classification.
