Homocysteine Topic Guide
Homocysteine: Homocysteine is an amino acid produced by the body, usually as a byproduct of consuming meat, fish or dairy. Elevated levels of homocysteine in the blood do not usually cause symptoms, but they raise the risk for heart disease. The cause of high homocysteine levels is usually dietary deficiencies in vitamin B6, vitamin B12, and folic acid. Treatment to lower homocysteine levels is vitamin supplementation.
Heart Attack A heart attack is an interruption in blood flow to the heart muscle. Arterial plaque rupture is often the cause of a heart attack. Symptoms of a heart attack may include chest pain, shortness of breath, sweating, and nausea. Emergency heart catheterization and thrombolytic therapy may be used to treat a heart attack.
