1 Univerzita Karlova v Praze 1. lékařská fakulta Některé aspekty patofyziologie plicní arteriální hypertenze a její výskyt v České republice Some aspects of pathophysiology of pulmonary arterial hypertension and its epidemiology in the Czech Republic MUDr. Pavel Jansa Praha 2011 2 Abstract Pulmonary arterial hypertension (PAH) is a group of diseases characterized by a progressive increase of resistance and pressure in pulmonary vascular bed. In all types of PAH the same four pathological processes are reported: vasoconstriction, inflammation, thrombosis and remodelling. The genetic background is essential for the development of PAH. We aimed to investigate the role of polymorphisms of endothelial nitric oxide synthase (eNOS) genes in PAH. We studied 142 PAH patients and 189 healthy subjects. We examined 3 polymorphisms of the eNOS gene, including the Glu298Asp polymorphism, 27-base pair (bp) variable numbers of tandem repeats (VNTR) and -786 T/C promoter gene polymorphism. Prevalence of 27-bp VNTR allele A was higher in patients with PAH compared with healthy controls. Patients with PAH associated with connective tissue diseases had higher prevalence of AA genotype compared with other PAH subgroups. The Glu298Asp polymorphism and -786 T/C polymorphism are not associated with PAH. Thrombotic arteriopathy is...
