May reduce false-positive CAD diagnoses; leaves open randomized confirmation of superiority over exercise ECG.
Does high-dose dipyridamole echocardiography improve diagnostic and prognostic accuracy compared to exercise ECG in patients with suspected coronary artery disease?
High-dose dipyridamole echocardiography offers superior specificity to exercise ECG for diagnosing coronary artery disease and provides independent prognostic value for predicting future cardiovascular events.
