[Hyperinsulinism--a new pathogenic cause of cardiovascular diseases].

Authors call attention to the insulin-resistance and following hyperinsulinism, as important and may be also the basic factor, which is determining for high cardiovascular morbidity and mortality. Authors analyze the pathogenesis of the Reaven's syndrome X, syndrome 5H and their symptoms--insulin-resistance, hyperinsulinism, hyperlipemia with obesity, hypertension and eventually hirsutism. Authors analyze the congenital and acquired factors, which influence its manifestation and so occurrence of the cardiovascular diseases in the adulthood. In the past paediatricians gave little attention to this problem because they supposed the problem as the problem of the adult medicine. We can see that full 5H syndrome is only the top of the iceberg with basis in childhood. In the prevention of the cardiovascular diseases the task of the paediatricians is therefore not substitutable and in future they need to give to the X syndrome extraordinary attention.
