Key result
In a review of 46 studies (5,353 patients), diagnostic variability of dobutamine stress echocardiography was related to the definition of a positive test, but not the definition of CAD.

Adopt uniform criteria for positive dobutamine tests to reduce diagnostic variability; extends evidence that methodological standards drive inconsistency in CAD evaluation.
Systematic Review (n=5,353)
What methodological factors cause diagnostic variability of dobutamine stress echocardiography for the diagnosis of coronary artery disease?
Methodological problems, particularly the definition of a positive test and patient selection, explain the wide range in diagnostic variability of dobutamine stress echocardiography.
Krenning et al. (2004) conducted a systematic review in Coronary artery disease (CAD) (n=5,353). Dobutamine stress echocardiography (DSE) was evaluated on Diagnostic variability. In a review of 46 studies (5,353 patients), diagnostic variability of dobutamine stress echocardiography was related to the definition of a positive test, but not the definition of CAD.
