Finding a cardiac rehabilitation program

If you have an ailing heart, starting — and sticking with — a cardiac rehabilitation program is an excellent undertaking. There are thousands of such programs across the United States. Some are in hospitals and medical centers, others operate out of other health care organizations, YMCAs, Jewish Community Centers, senior centers, senior centers, and gyms. The best programs offer supervised exercise with other ways to protect the heart. (Locked) More »

Coronary artery vasospasm

Vasospasm is a sudden narrowing of an artery, caused by a chemical imbalance, that can feel like a heart attack. It can disrupt the heart's rhythm or trigger a heart attack in a person with clogged arteries or a weak heart. If you have had episodes of chest pain but have been told your arteries are clear, you could have overly sensitive coronary arteries that spasm under certain conditions. Ask your doctor if a test to provoke vasospasm is right for you. It is done by injecting into the coronary arteries a medication such as ergonovine or acetylcholine that can make sensitive arteries constrict. If the test induces vasospasm, taking a calcium-channel blocker or long-acting nitrate could help prevent future episodes. More »
