Limiting Heart Muscle Damage

Treatments for a heart attack work to open the blocked artery to restore blood flow as fast as possible 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.
To learn more about treatment:
. Thrombolytic therapy.
. Other medications.
. Special procedures.

Thrombolytic Therapy

"Thrombolytic" or "clot-busting" therapy is used to stop a heart attack in its tracks. The drugs prevent or limit heart muscle damage by dissolving clots that block an artery. This opens up the artery and restores the blood flow.
Clot-busting drugs must be given immediately after heart attack symptoms begin. The sooner they are started, the more good they do-and the greater the chances are of a full recovery. To be most effective, they need to be given within 1 hour of the start of heart attack symptoms.

Other Medications

Besides thrombolytic, or clot-busting, drugs, other medications also are used to treat a heart attack and ischemia, as well as to ease chest pain. These drugs include aspirin, nitrates, such as nitroglycerin, and beta blockers.

  • Aspirin. Aspirin is now given to all patients who arrive at the hospital emergency department with a suspected heart attack. Aspirin acts to thin the blood and lessen the size of a blood clot during a heart attack.
  • Nitrates, including nitroglycerin. This relaxes blood vessels and stops chest pain.
  • Beta blockers. These reduce nerve impulses to the heart and blood vessels. This makes the heart beat more slowly and with less force.

Special Procedures

Doctors sometimes need to do a special procedure to improve blood flow to the heart muscle when the heart’s artery, or arteries, are narrowed or blocked. Two commonly used procedures are coronary angioplasty and coronary artery bypass graft surgery. These procedures can be done during a heart attack or later.
While a Heart Attack is happening, the sooner these procedures are done, the greater the chances of saving heart muscle and of surviving a heart attack.

Here's more on these special procedures :
  • 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 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.
    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.

Who's At Risk?

Heart attacks strike both men and women. However, some persons are more likely than others to have a heart attack because of their "risk factors." Risk factors are behaviors or conditions that increase the chance of a disease. Some of the risk factors for heart attack are beyond your control, but most can be modified to help you lower your risk of having a first–or repeat–heart attack.

Factors that increase the risk of a heart attack are :

Factors you cannot control
· Pre-existing coronary heart diseases, including a previous heart attack, a prior angioplasty or bypass surgery, or angina
· Age-In men, the risk increases after age 45; in women, the risk increases after age 55.
· Family history of early heart disease-a father or brother diagnosed before age 55; or a mother or sister diagnosed before age 65.

Factors you can control
· Smoking.
· High blood pressure.
· High blood cholesterol.
· Overweight and obesity.
· Physical inactivity.
· Diabetes.

Risk factors do not add their effects in a simple way. Rather, they multiply each other’s effects. So, it is very important to prevent or control risk factors that can be modified. If you have one or more of these factors, see your health care provider to find out how to reduce your risk of having a first or repeat heart attack.

What is a heart attack?

What Is A Heart Attack?

The heart works 24 hours a day, pumping oxygen- and nutrient-rich blood to the body. Blood is supplied to the heart through its coronary arteries. In coronary heart disease (CHD), plaques or fatty substances build up inside the walls of the arteries. The plaques also attract blood components, which stick to the artery wall lining. Called atherosclerosis, the process develops gradually, over many years. It often begins early in life, even in childhood.
The fatty buildup or plaque can break open and lead to the formation of a blood clot that seals the break. The clot reduces blood flow. The cycle of fatty buildup, plaque rupture, and blood clot formation causes the coronary arteries to narrow, reducing blood flow.
When too little blood reaches the heart, the condition is called ischemia. Chest pain, or angina, may occur. The pain can vary in occurrence and be mild and intermittent, or more pronounced and steady. It can be severe enough to make normal everyday activities difficult. The same inadequate blood supply also may cause no symptoms, a condition called silent ischemia.
If a blood clot suddenly cuts off most or all blood supply to the heart, a heart attack results. Cells in the heart muscle that do not receive enough oxygen-carrying blood begin to die. The more time that passes without treatment to restore blood flow, the greater the damage to the heart.
