- CVD
- Atheroma formation usually triggers CVD
- Arteries are made of several layers, including endothelial lining which is smooth and unbroken
- Damage to the endothelial layer triggers inflammatory response.
- Damage can be caused by high blood pressure
- Endothelial damage means the layer cant function normally
- The inflammatory response involves white blood cells moving into the area
- White blood cells and lipids from the blood clump together under endothelial layer, forms fatty streaks
- Over time, more white blood cells, lipids, connective tissue build up, harden and form plaque; an Artheroma
- Plaque semi-blocks lumen, of artery and restricts blood flow
- Blood pressure increases
- Hardening arteries caused by Atheroma, is called Atherosclerosis
- Blood pressure increases
- Plaque semi-blocks lumen, of artery and restricts blood flow
- Over time, more white blood cells, lipids, connective tissue build up, harden and form plaque; an Artheroma
- White blood cells and lipids from the blood clump together under endothelial layer, forms fatty streaks
- Damage can be caused by high blood pressure
- Damage to the endothelial layer triggers inflammatory response.
- Atheromas can increase the risk of a Thrombosis
- Atheromas can burst through the endothelium of an artery, damages wall and surface is left rough
- This causes a thrombosis to form at the site of damage
- Blood clot can block the artery fully, or become dislodged
- Blood flow to tissue is blocked, less oxygen to tissues
- Can result in Heart attacks, Strokes and deep vein thrombosis (Forms of CVD)
- Blood flow to tissue is blocked, less oxygen to tissues
- Blood clot can block the artery fully, or become dislodged
- This causes a thrombosis to form at the site of damage
- Atheromas can burst through the endothelium of an artery, damages wall and surface is left rough
