Abstract

Introduction:

methionine. Many reports confirm the correlation between hyper

homocysteinemia and cardiovascular disease. This study was aimed

at determining the effect of B12 and folate deficiency on the

homocysteine level after myocardial infarction.

Materials and methods:

study were patients with myocardial infarction (N = 48) and healthy

patients (N = 48) Eliza method was used to assay Homocysteine and

RIA for folic acid and vitamin B12.

Results:

(30.3 ± 5.3 μm/l) and the control group (11.1 ± 3.1) is significant (p<

0.001). There is no significant difference between Serum B12 in case

(297.1 ± 208.9 pm/l) and control group (261.5 ± 205.3) and it is true

about Serum folic acid of case (3.9 ± 2.9 ng/m) and control group

(4.3 ± 3.5). The homocysteine level of all patients and four of

healthy subjects is higher than normal. The folic acid Level of 11

patients and four healthy subjects is less than normal.

Conclusion:

of control group and this difference is not related to decrease of B12

Level, Physicians must pay attention to The other risk factors.

Key words:

cobalamine, cardiovascular disease.
