Eighty-one patients, randomly selected from our Cardiovascular Prevention Unit, were checked for fasting homocysteinemia levels between October 2000 and January 2001. Forty-nine females and 32 males aged between 22-73 years old were studied. 11/81 patients (13,6%) showed homocysteinemia over expected cutoff value (12 µmol/L). 10/81 (12,3%) presented homocysteinemia values between 12-15 µmol/L. These patients were selected undergo a methionine loading test in order to evaluate future hiperhomocysteinemia. 2/10 presented post prandial homocysteinemia over reference values. 3/81 (3,7%) were finally treated with vitamin supplement. 8/81 (9,9%) patients who showed homocisteinemia between 12-15 µmol/L but normal response to the loading test were instructed in improving quality food consumption and healthy living conditions.

Keywords : homocysteine; prevention; risk factors.
