SOURCES ON LINK BETWEEN HOMOCYSTEINE AND HEART DISEASE
A study that appears in this week's issue of the Journal of the American
Medical Association (JAMA) confirms research conducted here at the University
of Iowa linking elevated levels of an amino acid called homocysteine with
increased risk of heart disease.
The study published in JAMA was done by a team of Irish researchers
and was conducted in nine European countries.
If you would like to talk about this study and/or homocysteine, you
may contact Dr. Donald Heistad, head of the Division of Cardiovascular
Diseases, Department of Internal Medicine, in the UI College of Medicine.
Heistad was one of the leaders of the UI research team who linked moderately
high homocysteine levels with increased threat of cardiovascular disease.
The UI study was published last July in the Journal of Clinical Investigation.
Prior to the UI study, scientists knew that high levels of homocysteine
are a risk factor for stroke and heart attacks. The UI research was the
first in vivo study to link even moderate elevations of the amino acid
with increased cardiovascular risk.
Other research has indicated a link between lack of folic acid and elevated
levels of homocysteine. Folic acid is a B vitamin found in green, leafy
vegetables and in many fruits. It is also widely available as a vitamin
