Implication

May support dobutamine stress echo for CAD detection in referred patients; extends validation but leaves generalizability open.

Structured PICO

Does dobutamine stress echocardiography accurately detect coronary artery disease in patients undergoing coronary angiography?

P
Population
n=103 patients who underwent quantitative coronary angiography
I
Intervention
Dobutamine stress echocardiography (step-wise infusion of dobutamine to a maximum dose of 30 micrograms/kg/min)
C
Comparator
Quantitative coronary angiography (reference standard for ≥50% diameter stenosis)
O
Outcome
Diagnostic accuracy (sensitivity and specificity) of dobutamine-induced wall motion abnormalities for detecting significant coronary artery diseasesurrogate

Dobutamine stress echocardiography is a safe and accurate non-invasive method for detecting significant coronary artery disease compared to quantitative coronary angiography.
