Abstract

We investigated the diameter of epicardial coronary arteries in 12 patients (ten men) with dilated cardiomyopathy, and compared to 21 normal persons (14 men). Dilated cardiomyopathy patients were younger than controls with no difference in height, weight and body surface area. Ejection fraction was lower in dilated cardiomyopathy compared to normals (31+/-10% and 73+/-7%, respectively, P<0.001). Left ventricular mass was significantly larger (P=0.04). The sum of diameters of the proximal left anterior descending, circumflex and right coronary arteries (Total Coronary Diameter) in the dilated cardiomyopathy and controls was 13.4+/-2.7 and 10.5+/-1.5 mm (P<0.001). Absolute diameters of the left main, left anterior descending, circumflex, proximal right coronary artery and the right ventricular branch in dilated cardiomyopathy were also significantly larger as was Total Coronary Diameter adjusted for body surface area. Total Coronary Diameter adjusted for left ventricular mass, was significantly smaller (103.42+/-30.38, 146.00+/-41.59 mm/mg, respectively, P<0.03). Specific arteries in the dilated cardiomyopathy adjusted for left ventricular mass were significantly smaller, or had a tendency for smaller diameter compared to normals...Continue Reading

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
