Heart damage is not a disease itself. It is secondary problem depends on the severity of the heart attack. The heart is functioning muscle in a body. It requires supplying blood flow and oxygen to allow it to do work. When there isn’t sufficient blood supply, the muscle starts to suffer, and when there is no oxygen, the muscle starts to die. The heart attack occurs when the blood supply system of the heart is interrupted. The blocked artery under this situation damages the heart muscle. To diagnose the extensiveness of the heart damage, experts use several methods such as electrocardiogram or electrocardiography, 12-lead electrocardiogram, signal-averaged electrocardiogram, echocardiography, echocardiography, ransesophageal, echocardiography, and cardiac catheterization. These all are advanced electronic procedures operated with bio-tech machines.

At the time of the treatments for a heart attack blocked artery are opened to restore the blood flow as fast as possible to prevent the heart attaining more damage and reducing the chance of a repeat attack. The main treatment is thrombolytic (clot-busting) therapy. Other medications, and special procedures, such as angioplasty and coronary artery bypass surgery are also effective. To make sure the effectiveness of these treatments should be given within 1 hour of the start of the heart attack symptoms. The fast and quick treatment is only way to limit the damage of heart.
