[Blood fluidity in essential hypertension, arterial occlusive disease and diabetic angiopathies].

Microcirculatory disturbances are important complications in hypertension, arterial occlusive disease (PAVK) and diabetic angiopathies. The special haemorrheological diagnostics for the judgment of the terminal vascular bed tended to the comprehension of the haemorheological risk. Due to the increase of the aggregation of erythrocytes and viscosity of the plasma in peripheral arterial occlusive disease and diabetic angiopathies this risk proved to be distinctly increased, in diabetes mellitus without vascular complications and essential arterial hypertension it proved less distinctly increased. In hypertension the application of diuretic drugs should be done more critically and more controlled, in order to avoid conditions of hyperviscosity with their sequels for the microcirculation. The internal therapy in PAVK and diabetic angiopathies must include the amelioration of the disturbed blood fluidity.
