Why the study?
Does the administration of beta-blockers during the recovery phase of dobutamine stress echocardiography improve sensitivity for ischemia detection in patients with suspected coronary artery disease?
Does the administration of beta-blockers during the recovery phase of dobutamine stress echocardiography improve sensitivity for ischemia detection in patients with suspected coronary artery disease?
This review explores the mechanism and accuracy of administering beta-blockers during the recovery phase of dobutamine stress echocardiography to improve sensitivity for ischemia detection.
May support beta-blocker use in dobutamine stress echo recovery for ischemia detection; leaves open need for prospective validation before practice change.
Dobutamine stress echocardiography (DSE) is a successful technique for detection of ischemia in patients with suspected coronary artery disease (CAD). There are some data that administration of β-blocker after peak infusion of dobutamine can improve sensitivity. The goal of this manuscript is to review the current literature in regard to the mechanism and accuracy of post-dobutamine β-blocker administration for ischemia detection. In this review, we present 2 case reports followed by detailed review of the literature.
