Oxygen demand and collateral vessels of the heart. Factors influencing the severity of myocardial ischaemic injury after experimental coronary artery occlusion

Abstract

Epicardial electrocardiographic maps were used to assess the effect of heart rate, myocardial contractility, and oxygen need on the severity of myocardial ischaemic injury after acute coronary artery occlusion in dogs. The experimental data indicate statistically significant dependence of the severity of ischaemia on heart rate, contractility, and oxygen need of the heart. These dependences are highly influenced by the spontaneous collateral vessels of the heart.

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.
