Within two ment of vascular disease risk among men with higher years, Harvey Mudd, James Finkelstein, and their homocysteine concentrations indicated that plasma coworkers at the National Institutes of health (USA) homocysteine at only 12% above the upper limit of that the enzyme cystathionine ~- normal levels was associated with a 3. 4-fold increase had reported synthase was lacking in a liver biopsy specimen from in risk of acute myocardial infarction.
