Is increased plasma viscosity a risk factor for high blood pressure?
Angiology
|March 1, 1989
Summary
High blood pressure risk is linked to plasma viscosity, a measure of blood thickness. This study found plasma viscosity strongly associated with hypertension, suggesting it may indicate higher cardiovascular risk.
Area of Science:
- Cardiovascular epidemiology
- Hematology
- Public health
Background:
- Epidemiologic studies suggest hematocrit and fibrinogen may be risk factors for hypertension.
- Population surveys are crucial for identifying cardiovascular risk factors.
Purpose of the Study:
- To investigate the association between plasma viscosity and high blood pressure.
- To assess plasma viscosity as a potential cardiovascular risk factor in a large population sample.
Main Methods:
- A population survey of 5,312 individuals aged 25-64 years was conducted.
- Blood pressure, plasma viscosity, and hemoglobin were measured.
- Multiple logistic regression analyses were performed, controlling for age, sex, BMI, alcohol, smoking, and cholesterol.
Main Results:
- Plasma viscosity showed a significant association with high blood pressure, second only to body mass index.
- This association remained significant after controlling for multiple confounding factors.
- The study did not establish a causal relationship due to its cross-sectional design.
Conclusions:
- Plasma viscosity is a significant factor associated with high blood pressure.
- Increased plasma viscosity may have prognostic relevance for cardiovascular complications, potentially contributing to myocardial hypertrophy.
- The influence of antihypertensive drugs on blood viscosity should be considered in treatment selection.

Viscosity
When water is poured into a glass, it falls freely and quickly, whereas if honey or maple syrup is poured over a pancake, it flows slowly and sticks to the surface of the container. This difference in the flow of different kinds of liquids arises due to the fluid friction between the liquid layers and the liquid and the surrounding material. This property of fluids is called fluid viscosity. In this example, water has a lower viscosity than honey and maple syrup.

Factors affecting Blood pressure
Several physiological and lifestyle factors influence blood pressure (BP). Understanding these factors is crucial as they are significant in patient education and blood pressure management.

Hypertension and Regulation of Blood Pressure
Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...
Vascular Resistance
Vascular resistance is a critical concept in understanding blood flow dynamics in the circulatory system. It refers to the resistance that blood encounters as it flows through the blood vessels. This resistance is a key factor in determining blood pressure and cardiac workload.
The primary determinants of vascular resistance are vessel diameter, blood viscosity, and vessel length. Among these, vessel diameter plays the most significant role due to the fourth power relationship described by...

Viscosity
Viscosity is a property of fluids that measures their resistance to flow. It is influenced by factors such as the surface area of contact, the gradient of flow speed, and the fluid's viscosity constant, called the coefficient of viscosity. The coefficient of viscosity, also known as dynamic viscosity, is denoted by the symbol η. It determines the proportionality between the viscous force and the gradient of flow speed.Newton's law of viscosity states that the viscous force on a faster-moving...
Portal Hypertension
Portal hypertension is an increase in blood pressure within the portal venous system. Normally, this pressure is less than 5 mmHg. It is considered clinically significant when it rises above 10 mmHg. At this threshold, complications from altered blood flow and venous congestion emerge.EtiologyPortal hypertension arises from conditions that impede blood flow through the liver. The most common cause is cirrhosis, in which chronic liver injury leads to fibrotic scarring. This fibrosis narrows or...
