Usefulness of electron beam computed tomography scanning for distinguishing ischemic from nonischemic cardiomyopathy
Why the study?
Does electron beam computed tomography accurately distinguish ischemic from nonischemic cardiomyopathy in patients with ejection fraction <0.40?
Population
125 patients with cardiomyopathy (ejection fraction <0.40) and known coronary anatomy
Comparison
Electron beam computed tomography coronary… vs Coronary angiography (reference standard)
Design
Cohort, blinded
