What is a heart attack? A heart attack happens as a result of coronary heart diseases. Oxygen is essential for the heart muscles to survive. The reduction of oxygen-rich blood flow to the heart muscle causes a heart attack. The blood flow to the heart through the coronary artery is reduced or blocked by certain substances called plaque. Fats and cholesterol constituting the plaque may break the heart artery and forms clots around the plaque.
