BACKGROUND
Insertion/deletion (I/D) polymorphism of the angiotensin-converting enzyme (ACE) gene influenced the plasma concentration of the ACE, and is D allele have been repetitively suggested as a risk factor for myocardial infarction (MI).
METHODS
Two hundert thirty six male myocardial infarction survivors under 65 years and with body mass index and total plasma cholesterol levels under 95% of the Czech population were included in the study. As control group, 302 male controls (1% randomly selected group from the Czech population) were genotyped. I/D polymorphism in the ACE gene was determined using polymerase chain reaction.
RESULTS
The prevalence of the I/I, I/D and D/D genotypes was 0.218, 0.494 and 0.288, in the control group, and 0.178, 0.538 and 0.284, in the myocardial survivors, respectively. The male Czech population has the similar frequency of insertion and deletion alleles compared to other Caucasian populations. The frequencies of the alleles and genotypes of the ACE gene did not differ significantly between MI survivors and a control sample of the Czech population.
CONCLUSIONS
It was shown that the I/D polymorphism in the gene for ACE is not a genetic risk factor for myocardial infarction in the Czech population.
