Heart Attack

Myocardial Infarction ; ST-Segment-Elevation MI ; Transmural Myocardial infarction

A heart attack is a loss of blood flow to part of the heart. It can be mild or severe and may cause permanent damage. A blockage in blood vessels that supply the heart muscles is often the cause. It may be blocked with a build-up called plaque, a blood clot, or both.

Emergency medical care is important for a heart attack. Fast care may help to increase blood flow and stop or decrease damage. It may also stop the heart attack from being fatal.

Natural treatments are not helpful when heart attacks happen. Natural treatments may help to prevent conditions that lead to heart attacks. Most heart attacks are caused by atherosclerosis. See this topic for more information. Natural treatments may help to recover after a heart attack when used with standard care. The natural treatments in this topic will focus on the period following a heart attack.

Natural Therapies

Likely Effective

  • Vitamin B3 (Niacin) is found in grains, nuts, and meat. It is likely to improve stroke and heart attack risk.B13
  • Vitamin E is found in nuts, olive oil, and sunflower oil. It is likely to lower the risk of heart attack.B12

May Be Effective

  • Chelation therapy is a medicine that binds and removes items from the body. It is believed to bind to the calcium that is in plaque in the arteries. It may improve plaque as it moves through the blood. ( Note : Chelation therapy may cause severe health problems.)A1, A2
  • Coenzyme Q10 is a substance found in the body that can also be taken as a supplement. It may provide protective effects.B1, B2
  • Red yeast rice is a traditional Chinese medicine. May decrease future heart attacks.B3, B4
  • Tea consumption (caffeinated) may lower mortality after a heart attack.C1

Unlikely To Be Effective

  • L-rginine is an amino acid, a building block of protein. It has no effect on physical recovery after a heart attack.B5
  • Omega-3 fatty acidsare an unsaturated fatty acid. It is found in fish oil and available as a supplement. It has not been found to reduce the risk of another heart attack. ( Note : Omega-3 supplements may cause problems in people with certain health conditions.)B6-B10

Herbs and Supplements to Be Used With Caution

Talk to your doctor about any supplements or therapy you would like to use. Some can interfere with treatment or make conditions worse, such as:

  • Chelation therapy may cause severe problems, such as kidney damage. It should be avoided.
  • Omega-3 fatty acids may cause problems for people who take blood thinners or are diabetic.
  • Red yeast rice can lower cholesterol. It may cause problems in people who also take cholesterol-lowering medicine.B11
