Hyperviscosity in the elderly

Hyperviscosity (or hyperviscosity) is a clinical pathological syndrome characterized by abnormal blood rheology parameters due to an increase in blood viscosity or several factors causing blood viscosity and slow blood flow. . The elasticity of the blood vessel wall of the elderly gradually weakens, and the lumen gradually narrows, so the cells tend to be close to each other, causing the blood viscosity to increase, thereby slowing down the blood flow rate and leading to cardiovascular disease. Increased viscosity is related to increased levels of protein (globulin, fibrin) and lipids (triglycerides, cholesterol) contained in the plasma.
