BLOOD VISCOSITY IN HEALTHY SUBJECTS AND PATIENTS WITH CORONARY HEART DISEASE
Higher blood viscosity in males and coronary heart disease patients may contribute to cardiovascular disease. This study measured blood viscosity in healthy individuals and patients, revealing significant differences.
Area of Science:
- Cardiovascular Science
- Hematology
Background:
- Blood viscosity is a critical hemorheological parameter.
- Elevated blood viscosity is implicated in various vascular diseases.
Purpose of the Study:
- To investigate blood and plasma viscosity in healthy individuals across different age groups and sexes.
- To compare blood viscosity between healthy subjects and patients with coronary heart disease (CHD).
- To explore the potential role of blood viscosity in the pathogenesis of CHD.
Main Methods:
- Viscosity measurements of whole blood and plasma were performed.
- A cohort of 258 healthy subjects (ages 5-60) and 86 CHD patients were studied.
- Demographic data including sex and age were recorded.
Main Results:
- Children and young healthy females exhibited the lowest viscosity.
- Healthy males showed significantly higher blood viscosity than females.
- CHD patients presented with significantly higher blood viscosity compared to healthy controls of the same sex.
Conclusions:
- Increased blood and plasma viscosity may be a contributing factor to CHD development.
- Higher blood viscosity could play a role in the underlying vascular lesions associated with CHD.
- These findings highlight hemorheological factors in cardiovascular health and disease.

Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
