Learn about Heart Attacks

Heart attack or myocardial infarction is caused due to coronary artery blockage. Coronary arteries are the blood vessels which supply the heart with oxygen and nutrition. Overtime the inside of these arteries developed fibril fatty plagues of different sizes. These plagues are made of cholesterol and other substances floating through the bloodstream such as inflammatory cells, proteins and calcium. Many of the plague deposits are hard on the outside and soft on the inside.

The hard surface can crack or tear exposing the soft fatty inside. When this happens platelets come to the area and blood clots form around the plague. The artery narrows farther and in turn there is less room for blood to flow through the arteries. Finally, this results in the occlusion of the coronary arteries resulting in the death of the surrounding heart muscles. The patient experiences tightness, heaviness or constriction in the chest.
