Coronary Artery Disease
Medications
Many people have difficulty correctly taking their medicines for coronary artery disease (CAD). Often, they need to take several medicines at different times of the day. Also, for some people, the medicines are not affordable. But medicines are often an essential key to treatment, and people who do not take them as prescribed have an increased risk of complications and death.5
Medication Choices
Medications to treat symptoms and prevent complications
If you have symptoms of coronary artery disease, the following medicines may be prescribed to control symptoms and, in some cases, slow its progression:
- ASA or other antiplatelet medications help prevent blood clots in your coronary arteries.
- Beta-blockers slow your heart rate and lower your blood pressure to reduce the amount of work your heart has to do. They also reduce angina.
- Statins lower your blood cholesterol and may reduce your risk of a future heart attack. The National Cholesterol Education Program's (NCEP) guidelines provide a general reference to determine when to begin treatment with medicine to lower cholesterol.
- Nitrates (nitroglycerin and long-acting nitrates) relieve chest pain and other symptoms of angina.
- Calcium channel blockers slow your heart rate and lower your blood pressure to reduce your heart's workload. They also help dilate your coronary arteries and reduce angina.
- Angiotensin-converting enzyme (ACE) inhibitors lower your blood pressure and reduce the strain on the heart. They may also reduce your risk of a future heart attack or developing heart failure.
- Angiotensin II receptor blockers (ARBs) lower your blood pressure and reduce the strain on the heart. If you cannot tolerate certain side effects of an ACE inhibitor, your doctor may prescribe an ARB.
Anticoagulants may also be used following an angioplasty or bypass surgery. The anticoagulant warfarin may be used if you have CAD as well as atrial fibrillation or other complications.
What to Think About
Stable angina can often be controlled using medicine. If angina symptoms become worse, medicines can be adjusted. But angioplasty or bypass surgery may be necessary if angina symptoms get worse despite appropriate medication therapy. For angina that gets worse quickly or occurs at rest (unstable angina), hospitalization and urgent angioplasty with stenting, or bypass surgery may be needed. For more information, see the topic Heart Attack and Unstable Angina.
Although non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, relieve pain and inflammation much like ASA does, do not substitute NSAIDs for ASA, because they will not decrease your risk of another heart attack. If you need to take NSAIDs for a long time, talk with your doctor to see if it is safe for you. Some research suggests that long-term use of these medicines may raise your risk for CAD.
One study found that regular use of NSAIDs seemed to inhibit ASA's ability to prevent a first heart attack. But intermittent NSAID use did not interfere. (This trial studied male NSAID users only.)23 If you will need to take ASA or other NSAIDs for a long time, talk with your doctor about the interaction between ASA and other NSAIDs. Most doctors recommend taking ASA at least 2 hours before other NSAIDs, to reduce the chance of an interaction.
