Implication
DSE may aid post-MI CAD detection and risk stratification; leaves open need for randomized outcome trials before routine adoption.
Structured PICO
Does dobutamine stress echocardiography accurately detect coronary artery disease and predict post-infarction cardiac events?
P
Population
137 consecutive patients referred for dobutamine stress echocardiography (DSE) with suspected or documented coronary artery disease. Subgroups included 84 patients who also underwent coronary angiography and 35 patients who underwent DSE after uncomplicated myocardial infarction.
I
Intervention
Dobutamine stress echocardiography (DSE)
C
Comparator
Coronary angiography (as reference standard for diagnostic accuracy in 84 patients)
O
Outcome
Sensitivity and specificity for detecting and localising significant coronary artery disease, and predictive values for cardiac events following myocardial infarctionsurrogate
Dobutamine stress echocardiography is a safe, feasible, and accurate non-invasive imaging modality for detecting coronary artery disease and providing prognostic information after myocardial infarction.
