Does dobutamine stress echocardiography compare to dipyridamole stress echocardiography in diagnostic accuracy for coronary artery disease and myocardial ischaemia in patients referred for coronary angiography?
Dobutamine and dipyridamole stress echocardiography provide similar diagnostic accuracy for detecting coronary artery disease and myocardial ischemia, with differing hemodynamic profiles but comparable safety.
Salustri et al. (1992) studied this question.
