Insights

In men, higher hematocrit and blood viscosity correlate with carotid atherosclerosis. Hematocrit independently predicts this condition, suggesting its significance in cardiovascular risk assessment.

Area of Science:

  • Cardiovascular Medicine
  • Hematology
  • Medical Diagnostics

Background:

  • Blood viscosity and plasma viscosity are linked to atherosclerosis, but conclusive evidence, especially in women, is lacking.
  • Understanding hemorheological factors' role in atherosclerosis is crucial for cardiovascular disease prevention.

Purpose of the Study:

  • To determine if hematocrit, blood viscosity, and plasma viscosity are independently associated with carotid atherosclerosis.
  • To assess if these hemorheological markers can enhance the prediction of coronary heart disease (CHD) risk.

Main Methods:

  • Examined 892 participants for conventional CHD risk factors and hemorheological parameters.
  • Assessed carotid atherosclerosis using echo-Doppler, categorizing participants into no, low, and high atherosclerosis groups.

Main Results:

  • In men, increasing carotid atherosclerosis correlated with higher hematocrit and blood viscosity.
  • In women, increasing carotid atherosclerosis correlated with higher plasma viscosity.
  • Hematocrit was independently associated with carotid atherosclerosis in men, while blood viscosity's association diminished after adjustment.

Conclusions:

  • Hematocrit and blood viscosity are associated with carotid atherosclerosis in men.
  • Hematocrit appears to have an independent effect on carotid atherosclerosis in men, beyond viscosity-mediated effects.

Coronary Artery Disease I: Introduction

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers

Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...

Psychoneuroimmunology: Cardiovascular Disease

Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...
Hemorrhagic Stroke l: Introduction01:17

Hemorrhagic Stroke l: Introduction

A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...

Arteries of the Head and Neck

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...
