Key result
Adding atropine to DSE yields similar diagnostic accuracy and complication rates versus conservative protocols.

Does the addition of atropine to dobutamine stress echocardiography improve diagnostic accuracy or increase complication rates compared to conservative protocols in patients evaluated for CAD?
Absolute Event Rate: 84% vs 86%
The addition of atropine during dobutamine stress echocardiography does not increase complication rates and provides similar overall diagnostic accuracy, with a trade-off of increased sensitivity and decreased specificity.
Takeuchi et al. (1999) conducted an observational in Coronary artery disease (n=1,090). Dobutamine stress echocardiography with atropine vs. Conservative DSE protocols (30 µg/kg/min or 40 µg/kg/min without atropine) was evaluated on Diagnostic accuracy for detecting coronary artery disease. The addition of atropine during dobutamine stress echocardiography showed similar diagnostic accuracy (84% vs 86%) and complication rates compared to conservative protocols without atropine.
