title: Noninvasive diagnosis of ischemic cardiomyopathy by fluoroscopic detection of coronary artery calcification.
abstract: Twenty-four patients with severe congestive heart failure and cardiomegaly in whom the presence or absence of significant coronary disease could not be ascertained clinically underwent fluoroscopy for coronary artery calcification prior to cardiac catheterization. Ten of the patients were found to have significant coronary artery disease, and 14 had normal coronary arteriograms. Coronary artery calcification was found in all ten patients with significant coronary disease, and was absent in all of those patients with normal coronary arteriograms. We conclude that fluoroscopy for coronary artery calcification provides a reliable noninvasive method for differentiating ischemic from nonischemic cardiomyopathy.
