Key result
DSE is linked to coronary artery spasm in patients without known coronary disease.
Why the study?
The prevalence, predictors, and outcomes of coronary artery spasm during dobutamine stress echocardiography in patients without known coronary disease are not well characterized.
Suggests possible spasm risk with dobutamine stress echocardiography; hypothesis-generating and should not change practice pending further study.
Background and objective Given its high diagnostic and prognostic value and good safety profile, dobutamine stress echocardiography (DSE) is widely used in patients with known or suspected coronary...
