Associations of the known polymorphisms of the coagulation factor VII (FVII) gene (R353Q), the coagulation factor XIII (FXIII) gene (V34L) and the glycoprotein Ia (Gp1a) gene (C807T) with the occurrence of AMI were studied in 142 AMI survivors and 142 age- and sex-matched control subjects.
In order to determine the role of two polymorphisms in the factor VII gene (R353Q and intron 7 hypervariable region) in the susceptibility to develop early myocardial infarction, a total of 175 patients with acute myocardial infarction aged 50 years or less (mean age 41+/-7 years) and 200 controls (average age 42+/-6) without cardiovascular disease were genotyped for these polymorphisms.
