Prognostic Implications of Discordant Electrocardiogram and Imaging on Stress Echocardiography

Patients with discordant results have modest excess risk for adverse coronary events.

Stress echocardiogram testing is used to assess multiple endpoints, including exercise electrocardiographic (ECG) and imaging results. But what does it mean when ECG and imaging results are discordant? Duke University researchers assessed the prognostic implications of discordant results in 15,077 consecutive patients without known coronary artery disease (CAD) who underwent stress echocardiography.

Most patients (85.5%) had negative results on both ECG and imaging, but 8.5% had positive ECG with negative imaging, and 6% had positive imaging (regardless of ECG results). After a median 7-year follow-up, a composite endpoint of death, myocardial infarction, hospitalization for unstable angina, and coronary revascularization occurred in 8.5% of…
