Coronary arterial dimension-to-left ventricular mass ratio in idiopathic dilated cardiomyopathy.

This study demonstrated that, compared with normal controls, coronary artery dimensions are not increased appropriately for the increase in left ventricular mass in patients with nonischemic cardiomyopathy. The extent of coronary artery dimension to left ventricular mass mismatch did not correlate with the severity of heart failure. [ABSTRACT FROM AUTHOR]
