What happens if blood viscosity increases? ![]() It is affected by the presence of proteins produced in normal response to infection or inflammation, or abnormally in certain diseases (paraproteins). Plasma Viscosity (PV) is a laboratory test to assess the viscosity of a patient’s blood. Elevation of plasma viscosity correlates to the progression of coronary and peripheral artery diseases. Plasma fibrinogen concentration and plasma viscosity are elevated in unstable angina pectoris and stroke and their higher values are associated with higher rate of major adverse clinical events.

This increase seems independent of classical CHD risk factors and is disjoined from haematocrit and plasma viscosity, suggesting a possible direct effect of aging on red blood cells. Does plasma viscosity increase with age?Ĭonclusion: The present findings demonstrate that blood viscosity increases with age. Plasma exchange, phlebotomy, and rheopheresis are applied directly, whereas in indirect method, we regulate erythrocytes, platelets, and endothelial cells etc., that may have an effect on blood viscosity, (1, 2). Two therapeutic procedures are available for decreasing blood viscosity: direct and indirect. Hyperviscosity can be caused by your blood cells changing shape or by an increase in serum proteins, red blood cells, white blood cells, or platelets. Hyperviscosity syndrome is a condition that occurs when your blood becomes so thick that your body’s overall blood flow decreases. Increased blood levels of certain proteins, such as fibrinogen (which is increased in inflammation) or immunoglobulins (which are increased in inflammation or secreted by some tumours) cause the plasma viscosity to rise.
