Every year, about one million people suffer a heart attack (acute myocardial infarction or AMI). AMI is among the leading causes of hospital admission for Medicare beneficiaries, age 65 and older.
Scientific evidence indicates that the following processes of care represent the best practices for the treatment of AMI. Higher scores are better.
- AMI-1. Aspirin at Arrival
The heart is a muscle that gets oxygen through blood vessels. Sometimes blood clots can block these blood vessels, and the heart can't get enough oxygen. This can cause a heart attack. Chewing an aspirin as soon as symptoms of a heart attack begin may help reduce the severity of the attack. This chart shows the percent of heart attack patients who were given (or took) aspirin within 24 hours of arrival at the hospital.
Higher percentages are better.
- AMI-3. ACE Inhibitor or ARB for Left Ventricular Systolic Dysfunction (LVSD)
ACE (angiotensin converting enzyme) inhibitors and ARBs (angiotensin receptor blockers) are medicines used to treat patients with heart failure and are particularly beneficial in those patients with heart failure and decreased function of the left side of the heart. Early treatment with ACE inhibitors and ARBs in patients who have heart failure symptoms or decreased heart function after a heart attack can also reduce their risk of death from future heart attacks. ACE inhibitors and ARBs work by limiting the effects of a hormone that narrows blood vessels, and may thus lower blood pressure and reduce the work the heart has to perform. Since the ways in which these two kinds of drugs work are different, your doctor will decide which drug is most appropriate for you. If you have a heart attack and/or heart failure, you should get a prescription for ACE inhibitors or ARBs if you have decreased heart function before you leave the hospital.
- AMI-4. Smoking Cessation Advice/Counseling
Smoking increases your risk for developing blood clots and heart disease that can result in a heart attack, heart failure or stroke. Smoking causes your arteries to thicken and your blood vessels to narrow. Fat and plaque stick to the walls of your arteries, which makes it harder for blood to flow. Reduced blood flow to your heart may result in chest pain, high blood pressure, and an increased heart rate. Smoking is also linked to lung disease and cancer, and can cause premature death. It is important that you get information to help you quit smoking before you leave the hospital. Quitting may help prevent another heart attack.
Higher percentages are better.
- AMI-5. Beta Blocker at Discharge
Beta blockers are a type of medicine that is used to lower blood pressure, treat chest pain (angina) and heart failure, and to help prevent a heart attack. Beta blockers relieve the stress on your heart by slowing the heart rate and reducing the force with which your heart muscles contract to pump blood. They also help keep blood vessels from constricting in your heart, brain, and body. If you have a heart attack, you should get a prescription for a beta blocker before you leave the hospital.
