The problem of pulmonary hypertension (PH) is very essential for a large number of clinical conditions. It naturally occurs in many internal diseases, especially in patients with valvular heart disease, chronic lung pathology, vasculitis with vascular lesions of the pulmonary circle, pulmonary embolism, heart defects and many others. Increased blood pressure within the pulmonary artery (PA) is a natural step in the progression of chronic heart failure.
The relationship between the pathology of the cardiovascular system and the kidneys is studied intensively (Kobalava Zh.D. et al. 2010). This led to the creation of cardiorenal syndrome (Ronco C. et al, 2008). Cardiovascular disease is an independent risk factor for chronic kidney disease (Elsayed E.F. et al, 2007).
