The most common sites of myocardial infarction are in the left ventricle, that chamber of the heart which has the greatest workload. Tissue changes that occur in the myocardium are related to the extent to which the cells have been deprived of oxygen.
CORONARY ARTERY DISEASE (CAD) is the most significant threat to the myocardium, as occlusions in the coronary arteries deprive the myocardium of blood and thus oxygen. When the consequence is MYOCARDIAL INFARCTION, CARDIAC ARREST can result.yocardial cells thus can contract independent of external stimulation. The myocardial fibers of the atria have a different configuration from those of the ventricles. The CORONARY ARTERIES provide an extensive network to supply blood to the myocardium, which requires about 70 percent of the bloodâs oxygen.
