Regarding the FXIII-B gene polymorphisms, p.His95Arg polymorphism increases the risk of stroke and reduces the risk of myocardial infarction [34], while VS11, c.1952 + 144 C>G (Intron K), polymorphism lowers the risk of coronary atherosclerosis and myocardial infarction [32,35]. This evidence concerns the gene F13B and myocardial infarction.
