Cardiovascular disease is the leading killer. There are many factors that can play a role in the development and progression of the disease.
is an amino acid found in the blood that has been connected to increase chance of developing heart disease. While this is known to be a factor, treatment is less certain. Research has shown that B-vitamins can be effective in decreasing levels of homocysteine in the blood but it is not clear if this will reduce the risk of heart disease.
The Haukeland University Hospital in Norway conducted a study to try to find a connection between B vitamins for homocysteine levels and heart disease or death. The study published in
, found that treatment with vitamin B or
did lower homocysteine blood levels but it did not effect heart events or death.
About the Study
The randomized double blind controlled study followed 3096 patients after undergoing a
. The patients were randomly assigned to one of four groups based on the daily oral treatment of:
The doses for all were folic acid (0.8mg), B12 (0.4 mg), and B6 (40 mg). Patients were followed for death,
, hospitalization for unstable
, and non fatal
. There were no significant differences between groups in the rate of any death, cardiovascular death, or heart attack. The homocysteine lowering therapy was linked with a decreased risk of stroke but the studies author did not believe this to be a true effect. The treatment groups also had an increase in hospitalization for unstable angina.
The study lasted 7 years but was ended early because of participants concern after negative results from another study reviewing homocysteine-lowering therapy were released. There were methodological limitations which mean that the results may not be fully reliable.
