What does CVD stand for?
Cardiovascular disease
CVD refers to a general term for conditions affecting the heart and blood vessels.
AAHMS
Name 5 conditions included in CVD.
- Atherosclerosis
- Hypertension
- Angina
- Myocardial infarction
- Stroke
What is the Endothelium (ED)?
A monolayer of endothelial cells lining the blood interface throughout the CVS including cardiac chambers
The Endothelium plays a critical role in vascular function.
Define shear stress in the context of the cardiovascular system.
Frictional force of blood on endothelial cells
Shear stress influences endothelial function and health.
What is the glycocalyx (GX)?
A carbohydrate-rich protective layer covering the endothelium
The glycocalyx is crucial for vascular health.
List 3 functions of the glycocalyx.
- Regulates permeability
- Controls Nitri Oxide production
- Acts as a mechanosensor of blood shear stress
These functions are vital for maintaining vascular homeostasis.
What can damage the glycocalyx (5)?
- Inflammation
- Hyperglycaemia
- Endotoxemia
- Oxidised low-density lipoproteins
- Abnormal blood shear stress
Damage to the glycocalyx can lead to vascular dysfunction.
