How Is a Heart Attack Treated?
Early treatment for a heart attack can pr event or limit damage to the heart muscle. Acting fast, by calling 9–1–1 at the first symptoms of a heart attack, can save your life. Medical personnel can begin diagnosis and treatment even before you get to the hospital.
Immediate Treatment
Certain treatments usually are started right away if a heart attack is suspected, even before the diagnosis is confirmed. These include:
- Aspirin to prevent further blood clotting
- Nitroglycerin to reduce your heart’s workload and improve blood flow through the coronary arteries
- Oxygen therapy
- Treatment for chest pain
Once the diagnosis of a heart attack is confirmed or strongly suspected, doctors start treatments promptly to try to restore blood flow through the blood vessels supplying the heart. The two main treatments are clot-busting medicines and percutaneous coronary intervention, also known as coronary angioplasty, a procedure used to open blocked coronary arteries.
Clot-Busting Medicines
Thrombolytic medicines, also called clot busters, are used to dissolve blood clots that are blocking the coronary arteries. To work best, these medicines must be given within several hours of the start of heart attack symptoms. Ideally, the medicine should be given as soon as possible.
Percutaneous Coronary Intervention
Percutaneous coronary intervention is a nonsurgical procedure that opens blocked or narrowed coronary arteries. A thin, flexible tube (catheter) with a balloon or other device on the end is threaded through a blood vessel, usually in the groin (upper thigh), to the narrowed or blocked coronary artery. Once in place, the balloon located at the tip of the catheter is inflated to compress the plaque and related clot against the wall of the artery. This restores blood flow through the artery. During the procedure, the doctor may put a small mesh tube called a stent in the artery. The stent helps to keep the blood vessel open to prevent blockages in the artery in the months or years after the procedure.
Other Treatments for Heart Attack
Other treatments for heart attack include:
- Medicines
- Medical procedures
- Heart-healthy lifestyle changes
- Cardiac rehabilitation
Medicines
Your doctor may prescribe one or more of the following medicines.
- ACE inhibitors. ACE inhibitors lower blood pressure and reduce strain on your heart. They also help slow down further weakening of the heart muscle.
- Anticlotting medicines. Anticlotting medicines stop platelets from clumping together and forming unwanted blood clots. Examples of anticlotting medicines include aspirin and clopidogrel.
- Anticoagulants. Anticoagulants, or blood thinners, prevent blood clots from forming in your arteries. These medicines also keep existing clots from getting larger.
- Beta blockers. Beta blockers decrease your heart’s workload. These medicines also are used to relieve chest pain and discomfort and to help prevent another heart attack. Beta blockers also are used to treat arrhythmias (irregular heartbeats).
- Statin medicines. Statins control or lower your blood cholesterol. By lowering your blood cholesterol level, you can decrease your chance of having another heart attack or stroke.
You also may be given medicines to relieve pain and anxiety, and treat arrhythmias. Take all medicines regularly, as your doctor prescribes. Don’t change the amount of your medicine or skip a dose unless your doctor tells you to.
Medical Procedures
Coronary artery bypass grafting also may be used to treat a heart attack. During coronary artery bypass grafting, a surgeon removes a healthy artery or vein from your body. The artery or vein is then connected, or grafted, to bypass the blocked section of the coronary artery. The grafted artery or vein bypasses (that is, goes around) the blocked portion of the coronary artery. This provides a new route for blood to flow to the heart muscle.
Heart-Healthy Lifestyle Changes
Treatment for a heart attack usually includes making heart-healthy lifestyle changes. Your doctor also may recommend:
- Heart-healthy eating
- Aiming for healthy weight
- Managing stress
- Physical activity
- Quitting smoking
Taking these steps can lower your chances of having another heart attack.
Cardiac Rehabilitation
Your doctor may recommend cardiac rehabilitation (cardiac rehab) to help you recover from a heart attack and to help prevent another heart attack. Nearly everyone who has had a heart attack can benefit from rehab. Cardiac rehab is a medically supervised program that may help improve the health and well-being of people who have heart problems.
The cardiac rehab team may include doctors, nurses, exercise specialists, physical and occupational therapists, dietitians or nutritionists, and psychologists or other mental health specialists.
Rehab has two parts:
- Education, counseling, and training. This part of rehab helps you understand your heart condition and find ways to reduce your risk for future heart problems. The rehab team will help you learn how to cope with the stress of adjusting to a new lifestyle and how to deal with your fears about the future.
- Exercise training. This part helps you learn how to exercise safely, strengthen your muscles, and improve your stamina. Your exercise plan will be based on your personal abilities, needs, and interests.
