Is folate supplementation indicated for patients with CAD?
Metadata[+] Show full item record
There is insufficient evidence to advocate the routine use of folate supplementation for the treatment of coronary artery disease (CAD). High levels of serum homocysteine have been associated in several studies with an increased risk for CAD (strength of recommendation [SOR]: B, associated in case-control studies). Folate supplementation decreases the level of serum homocysteine (SOR: A, meta-analysis of randomized controlled trials). This indirect evidence suggests that folate supplementation may be of benefit in slowing the progress of arteriosclerosis.
