Abstract
The aim of our study was to determine the prevalence of the factor V mutation (position 1691 G→A) in patients with angiographically diagnosed coronary artery disease and myocardial infarction and, as a control, in blood donors. This mutation has already been proved to be the main genetic risk factor for venous thrombosis. In order to detect this mutation in exon 10 of the factor V gene we established a microtiter plate based hybridization assay for the specific detection of wild-type and mutant sequences in factor V gene segments, obtained after amplification by polymerase chain reaction. This test enables us to screen a large number of samples. The mutation was detected in 29 of 317 coronary artery disease (CAD) patients (9.1%) and 18 of 190 blood donors (9.5%) investigated. The mean activated protein C resistance ratios were 3.18 and 3.11, with nearly identical distribution. No increased prevalence of the factor V mutation was found in the CAD group. In 10 of 29 CAD patients (35%) with the factor V 1691 G→A mutation and in 124 of 288 CAD patients without the mutation (43%) there was a history of myocardial infarction. From our data we conclude that there is no increased risk of developing coronary atheroma or consecutive myocardial infarction resulting from the factor V mutation with protein C resistance.
