What is the prognostic value of stress echocardiography for patients with atypical chest pain?
Metadata[+] Show full item record
Patients with atypical chest pain and no history of cardiovascular events (coronary artery disease, unstable angina, or history of percutaneous transthoracic coronary angioplasty [PTCA]) and a negative stress echocardiography test are unlikely to experience a cardiovascular event in the next 1 to 4 years. However, the positive predictive value of the test in this population is low, indicating that a positive stress echocardiography is less useful for prognostic purposes (strength of recommendation: B, based on multiple cohort studies).
