A Heart Attack is a loss of heart muscle caused by acute lack of oxygen (hypoxia) due to a blood clot in a coronary artery of the heart.
Coronary arteries are the blood vessels that supply the heart muscle with oxygen-rich blood. This is often experienced as chest pain, but can also provide more diffuse symptoms such as shortness of breath, pain radiating to the arm, neck and abdomen.
Each year over 735 000 people in the US suffer a heart attack, of which for 635 000 it is their first heart attack1. Every year approximately 120 000 die from heart attacks in the United States.
Methods of treatment of heart attack aim to restore blood flow in the blood vessels the blood clot blocked. It is critical that the individual comes to the hospital as soon as possible. The faster the flow of blood succeeds to normalize, the less damage is dealt. In the acute stage, the blood flow is normalized with the principle of two methods: Percutaneous coronary intervention (PCI / angioplasty) and bypass surgery (CABG).
