Brazil Artery

Acute Infarto of the myocardium the cardiovascular illnesses almost continue being the first cause of death in Brazil, being responsible for 32% of all the deaths in the country and representing the third bigger cause of internment. Amongst them if it detaches the Acute Infarto of the Myocardium – THEY WENT, one of the biggest causes of morbidade and mortality, although the therapeutical advances of the last decades, just because great part of the patients does not receive the treatment adequate. Studies epidemiologists around disclose taxes of general mortality of 30%, being that half of the deaths occurs in first the two hours of the event and 14% die before receiving attendance medical. Fisiopatologia the arteries are hollow pipes. Inside they are smooth and elastic allowing that the blood flows freely. The suppliment of blood for the heart is made through the coronary arteries, that directly appear of the artery aorta. They are the two main coronary arteries: the right coronary artery and the left coronary artery that soon is branched off in two great arteries, previous the descending artery and artery circunflexa.

The interruption of the suppliment or sanguine flow for the cardiac muscle is caused by the blockage (aterosclerose) of a coronary artery or one of its branches. The typical injury of the advanced forms of the illness is the plate fibrosa- esbranquiada formation that protunde in the light of the vase. It is covered by a fibrosa layer that consists of some layers of cells flattened absorbed in dense a extracellular fabric matrix conjunctive, to the side of lamnulas of amorphous material, proteoglicanos, colgenas staple fibres and smooth muscular cells. In the interior of the plate, below of the fibrosa layer, she has an accumulation of the frothy, complete cells or routes, and of fabric conjunctive. The frothy cells are derived from the macrophages (sanguineous macrcitos and linfcitos, and smooth muscular cells of the arterial wall) that they contain gotculas of fat, mainly under the free and esterificado cholesterol form.
