Prognostic impact of stress echocardiography with discordant stress electrocardiography in patients with suspected coronary artery disease

Abstract

O r i g i n a l A r t i c l e METHODS This was a retrospective observational study of all patients who underwent stress echocardiography in 2012 at Changi General Hospital, Singapore. All study patients were followed up for 18 months via electronic medical records. RESULTS There was no difference in the major adverse cardiovascular events (MACE) outcome of patients with normal stress echocardiography and normal stress ECG (reference group) as compared with patients with normal stress echocardiography but positive (discordant) stress ECG (odds ratio 2.02, 95% confidence interval 0.82-4.98; p = 0.125). CONCLUSION This study will help to reassure cardiologists that discordant results (negative stress echocardiography but positive stress ECG) do not portend a higher risk of MACE when compared to concordant results (i.e. both stress echocardiography and stress ECG are negative).

Exercise electrocardiography combined with stress echocardiography for predicting myocardial ischemia in adults

“…Coronary angiography (CAG) is the gold standard for diagnosing CAD and MI, whereas invasive operations are high-risk treatment methods that are not easily accepted by patients, such as lack of expensive devices and experienced operators (3,4). Prior to the development of CAG, electrocardiography (ECG) was the best noninvasive technique for CAD/MI diagnosis (5). In 1979, stress echocardiography (SE) was classified as an invaluable technique that combines echocardiography and ECG with stress testing (6).…”
