Treatments for a heart attack are designed to open the blocked artery and restore blood flow to the heart as fast as possible.
This is to prevent or limit damage to the heart muscle, and to lessen the chance of a repeat attack.

The main treatments are thrombolytic ("clot-busting") therapy, other medications, and special procedures, such as angioplasty and coronary artery bypass surgery.
To be most effective, these treatments must be given fast – within 1 hour of the start of heart attack symptoms. Acting fast can save your life and limit damage to your heart.
This article will discuss angioplasty and bypass surgery as means of opening a blocked coronary artery.
Angioplasty and bypass surgery are special procedures to improve blood flow to the heart muscle when the heart’s artery, or arteries, are narrowed or blocked.
These procedures can be done during a heart attack or later. The sooner these procedures are done, however, the greater the chances of saving heart muscle and of surviving a heart attack.
* Coronary Angioplasty, or Balloon Angioplasty. In this procedure, a fine tube, or catheter, is threaded through an artery into the narrowed heart vessel.
The catheter has a tiny balloon at its tip. The balloon is repeatedly inflated and deflated to open and stretch the artery, improving blood flow. The balloon is then deflated, and the tube is removed.
Doctors often insert a stent during the angioplasty. A wire mesh tube, the stent is used to keep an artery open after an angioplasty. The stent stays permanently in the artery.
In up to a third of those who have an angioplasty, the blood vessel becomes narrowed or blocked again within 6 months.
This is more likely to happen if you smoke, or have diabetes or unstable angina.
Vessels that reclose may be re-opened with another angioplasty or need a coronary artery bypass graft. Even an artery with a stent can reclose.

* Coronary Artery Bypass Graft Operation.

Also known as "bypass surgery," the procedure uses a piece of vein taken from the leg, or of an artery taken from the chest or wrist.
This vein is attached to the heart artery above and below the narrowed area, thus making a bypass around the blockage. Sometimes, more than one bypass is needed.
The following, excellent, 3 minute video clip clearly shows how an artery bypass graft operation is performed.

Bypass surgery may be needed due to various reasons, such as an angioplasty that did not sufficiently widen the blood vessel, or blockages that cannot be reached by, or are too long or hard for, angioplasty.
In certain cases, bypass surgery may be preferred. For instance, it may be used for persons who have both coronary heart disease and diabetes.
A bypass also can close again. This happens in more than 10 percent of bypass surgeries, usually after 10 or more years.
