Lowering homocysteine levels may prevent cardiovascular impairments? Possible therapeutic behaviors

Blood Coagul Fibrinolysis. 2012 Dec;23(8):677-9. doi: 10.1097/MBC.0b013e3283597586.

Abstract

Homocysteine (Hcy) is metabolized through two pathways, requiring folates and B6-12 vitamins as cofactors. Increased Hcy concentration is responsible for early atherosclerosis with possible acute cardiovascular events. Ample evidence has demonstrated that Hcy lowering with folic acid and B vitamin supplementation, even if reduces Hcy serum levels, is unable to lower cardiovascular risk. On the contrary, omega-3 fatty acids and some nutraceuticals, such as N-acetyl cysteine, taurine, or S-adenosyl-methionine, reduce both Hcy serum concentration and cardiovascular risk. Instead, antiplatelet drugs, such as aspirin and clopidogrel or ticlopidine and statins only antagonize vascular derangements. Finally, metformin, some lipid-lowering drugs, and some diuretics should be avoided because they can increase Hcy levels.
