What is homocysteine?
Homocysteine is an amino acid produced during the metabolism of methionine. High levels of homocysteine in the blood are associated with an increased risk of cardiovascular disease, stroke, and other health complications. Factors such as diet, genetics, and certain medical conditions can influence homocysteine levels.
What are the implications of homocysteine on human health?
High levels of homocysteine in the blood are believed to increase the chance of heart disease, stroke, Alzheimer's disease, and osteoporosis.
What do elevated homocysteine levels mean for a cardiac patient?
Elevated homocysteine levels are a prognostic indicator of arteriosclerosis and poor cardiovascular health. Diets rich in B vitamins, such as folic acid, B6 and B12, tend to reduce serum homocysteine levels, It is not clear whether lowering homocysteine levels in the cardiac patient will lead to improved outcomes, with respect to morbidity and mortality (especially as cardiovascular diseases tend to be multifactorial, often including a significant genetic component).
What is the amino acid homocysteine used for in the body?
Homocysteine is an intermediate in the metabolism of methionine, an essential amino acid. It can be converted back to methionine or further metabolized into cysteine or excreted from the body. Elevated levels of homocysteine are associated with an increased risk of cardiovascular disease.
What is homocysteine blood test?
A homocysteine blood test measures the level of homocysteine in your blood. Homocysteine is an amino acid that plays a role in heart health, and high levels have been associated with an increased risk of cardiovascular disease. The test can help assess your risk for heart disease and may be recommended for certain individuals with a family history of heart problems.
High homocysteine levels associated with ischemia may be treated with which supplements?
High homocysteine levels may be treated with vitamin B6, B12 and folic acid.
What raises homocysteine levels?
Frequently the cause is heart disease.
How may homocysteine blood levels be controlled?
Lowering homocysteine blood levels is linked to increasing the intake of folic acid and vitamins B6 and B12. The healthiest way to increase intake is by eating more foods that are high in these substances
What nutritional supplements are recommended to promote good vascular health?
Folic acid, which helps lower homocysteine levels and increases the oxygen-carrying capacity of red blood cells. Vitamins B6 and B12, which help lower homocycteine levels
What amino acid intermediate causes arterial damage?
Homocysteine is an amino acid intermediate that can cause arterial damage. Elevated levels of homocysteine in the blood have been associated with an increased risk of developing cardiovascular diseases, including the development of atherosclerosis or the hardening and narrowing of the arteries. High homocysteine levels can damage the lining of blood vessels, promote blood clot formation, and contribute to inflammation, ultimately leading to arterial damage.
Supplements of what amino acids are reported to lower blood pressure and reduce homocysteine levels?
Arginine
When present in the blood levels in elevated levels the amino acid can damage arterial walls and increase the risk of coronary artery disease?
homocysteine
