[Evaluation of resistance to activated protein C in myocardial infarction patients].

It is known that resistance to activated protein C (APCR), often associated with a single point mutation (Arg506--Gln) in the coagulation factor V gene (factor V Leiden), is the most frequent inherited abnormality of blood coagulation. It plays a key role as pathogenetic factor of venous thromboembolism, but its association with an increased risk of arterial thrombosis is uncertain. Aim of the present study was to evaluate the prevalence of APCR in men, who suffered myocardial infarction more than 6 months earlier and without cardiovascular risk factors (hypercholesterolemia, smoking, diabetes, obesity and hypertension).The study was carried on 20 men aged65 years who have suffered myocardi…
