[Erythrocytoses in patients with dilated and ischemic cardiomyopathy.].

The aim of research was to evaluate the impact of erythrocytoses on processes of cardiovascular system's remodelling in patients with dilated and ishaemic cardiomyopathies. 35 (42,2%) patients with dilated cardiomyopathy (DCMP) with erythrocytoses, 19 (23,5%) without erythrocytosis, 34 (28,4%) patients with ishaemic cardiomyopathy (ICMP) with erythrocytosis and 50 (60,1%) without erythrocytosis were included in the study. It has been established that erythrocytoses don't wield major influence on the heart's haemodynamics, they appear as a consequence of main diseases and not as their reason, which confirms the domination of congestive heart failure's signs of III-IV stages. In patients with DCMP and ICMP signs of tissue hypoxia were established as well as oxygen reduction in arterial blood to 60,70 ± 1,24 mm Hg in cases of DCMP and 59,60 ± 1,24 mm Hg in cases of ICMP (in verification 75,44 ± 0,93) - p < 0,001. Arguably, erythrocytoses in cases of DCMP and ICMP are a consequence of congestive heart failure, leading to hypoxic erythrocytosis.
