Dual imaging stress echocardiography versus computed tomography coronary angiography for risk stratification of patients with chest pain of unknown origin
Why the study?
Does dual imaging stress echocardiography provide comparable prognostic value to computed tomography coronary angiography for predicting major cardiac events in patients with chest pain of unknown origin?

Implication
May aid risk stratification in chest pain evaluation; leaves open prospective validation of incremental value.
Structured PICO
Does dual imaging stress echocardiography provide comparable prognostic value to computed tomography coronary angiography for predicting major cardiac events in patients with chest pain of unknown origin?
P
Population
131 patients with chest pain of unknown origin and suspected coronary artery disease (CAD), mean age 68 ± 9 years, 76 men.
I
Intervention
Dual imaging stress echocardiography (dipyridamole up to 0.84 mg/kg over 6 min stress echo with coronary flow reserve [CFR] assessment of the left anterior descending artery [LAD] by Doppler).
C
Comparator
Computed tomography coronary angiography (CTCA).
O
Outcome
Major cardiac events (composite of death, nonfatal myocardial infarction, and late [≥6 months] coronary revascularization) at median 7 months follow-up.composite
Dual imaging stress echocardiography and CTCA provide independent and comparable prognostic value for risk stratification in patients with chest pain of unknown origin.
