[Blood viscosity in ischemic heart disease with different types of hyperlipoproteinemia].

Fifty patients with chronic forms of ischaemic heart disease were examined, their blood viscosity being determined with the aid of a rotational viscosimeter, and their hematocrit and fibrinogen levels being measured. Some increase in blood viscosity was found in patients with ischaemic heart disease with a tension shift of 0.7 and 0.5 dyn/cm2. In analysing the interrelationship between the blood viscosity figures and the risk factors inherent in ischaemic heart disease it was found that smoking results in an increasing blood viscosity with low tension shifts. The highest blood viscosity with low tension shifts. The highest blood viscosity values were found in patients with IIb and IV types of hyperlipoproteinemia. A direct correlation was established between the level of triglycerides and blood viscosity with a tension shift of 0.7 dyn/cm2.
