Beta blockers preserve dobutamine stress echo accuracy; leaves open whether they increase ischemic severity or limit risk stratification.
Does beta blocker therapy impact the diagnostic accuracy and ischemic response of dobutamine-atropine stress echocardiography?
Beta blocker therapy does not reduce the diagnostic sensitivity of dobutamine-atropine stress echocardiography, but it may lead to more severe myocardial ischemia during testing and preclude stratification of a positive response.
