title: Prevention of myocardial infarction by vitamin B6.
abstract: Vitamin B6 is effective in the treatment of carpal tunnel syndrome and related disorders in patients with vitamin B6 deficiency. Hyperhomocysteinemia, a risk factor for atherosclerosis, is associated with deficiencies of vitamin B6, folate, and cobalamin. Patients who were given vitamin B6 for carpal tunnel syndrome and other degenerative diseases were found to have 27% of the risk of developing acute cardiac chest pain or myocardial infarction, compared with patients who had not taken vitamin B6. Among elderly patients of the author (JE) expiring at home, the average age at death from myocardial infarction was 8 years later in those who had taken vitamin B6, compared with those who had not taken vitamin B6. The preventive effect of vitamin B6 on progression of coronary heart disease may be related to increased formation of pyridoxal phosphate, the coenzyme that is required for catabolism of the atherogenic amino acid, homocysteine.
