Key result
A negative stress echocardiogram predicted a 99% 3-year event-free survival for cardiac events, compared with 95% for a negative stress ECG, identifying patients at very low risk.

A negative stress echocardiogram may support low-risk discharge decisions in emergency department atypical chest pain; leaves open prospective validation.

Does stress echocardiography predict future cardiac events in patients presenting to the emergency department with atypical chest pain?
Absolute Event Rate: 99% vs 95%
A negative stress echocardiogram in ED patients with atypical chest pain carries an excellent 3-year prognosis, identifying patients who can safely forgo hospital admission.
Colon et al. (1999) conducted a cohort in Atypical chest pain (n=105). Stress echocardiography vs. Stress ECG was evaluated on Cumulative event-free survival for cardiac events (myocardial infarction, coronary revascularization, and cardiac death) at 3 years for a negative test. A negative stress echocardiogram predicted a 99% 3-year event-free survival for cardiac events, compared with 95% for a negative stress ECG, identifying patients at very low risk.
