The capillarity of left ventricular tissue of rats subjected to coronary artery occlusion

Abstract

The remodelling of the capillary bed is not uniform throughout the cardiac tissue in coronary-occluded rat hearts. CDAs decreased in the non-ischemic zone but increased in the transition zone. The rate of capillary angiogenesis failed to parallel the development of hypertrophy in the transition zone over 30 days, as could be seen from the significant reduction in the percentage of venular capillary portions.
