Abstract

A computer simulation of the left coronary outflow response to branch occlusion was carried out, using physiological data derived from canine left coronary artery generated on an IBM 360/44 in order to provide multidimensional analysis of the problem of the distribution of flow within the myocardium. During coronary occlusion in this computer model, distal impedance varied little during the occlusion of one or the other arterial brance. This observation was taken as a boundary condition in the simulation exercise. Some of the important factors in the intramyocardial distribution of flow are discussed.

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.
