Atherosclerosis
- Def: Disease process that leads to CHD and strokes
(CVDs). Fatty deposits (atheroma) can block arteries
directly or increase possibility of blot clot formation
(thrombosis)
- DEVELOPMENT OF ATHEROSCLEROSIS
- 1) Damage to endothelial lining (artery lining)
- Through smoking, high blood
pressure etc
- 2) Inflammatory response. White blood cells
move into the artery wall
- 3) Cholesterol build up, leading to atheroma formation
- 4) Build-up of calcium salts and fibres, leading
to plaque formation
- 5) Leads to narrowing of artery and loss of
elasticity - hardening of arteries
- 6) Narrowing of artery leads to increased blood
pressure, so the cycle is never ending
- 6) Narrowing of artery leads to increased blood
pressure, so the cycle is never ending
- 5) Leads to narrowing of artery and loss of
elasticity - hardening of arteries
- An atheroma is a fatty deposit
- HEALTH EFFECTS OF AN ATHEROMA
- Increased blood pressure - causes damage
to kidneys and retina, and could cause
strokes
- Stroke - an interruption to blood supply of brain,
potentially causing paralysis or death
- Stroke - an interruption to blood supply of brain,
potentially causing paralysis or death
- Aneurysm - increased blood pressure (due to
blockage) could lead to bursting of an artery
and internal bleeding
- Angina - chest pain felt during excerise, caused by
reduced blood flow to heart due to narrowing of
coronary arteries
- If a coronary artery becomes totally
blocked (by a clot) heart can be starved
of oxygen and die
- If a coronary artery becomes totally
blocked (by a clot) heart can be starved
of oxygen and die
- Increased blood pressure - causes damage
to kidneys and retina, and could cause
strokes
- HEALTH EFFECTS OF AN ATHEROMA
- 4) Build-up of calcium salts and fibres, leading
to plaque formation
- 3) Cholesterol build up, leading to atheroma formation
- Increased risk of
blood clotting in
artery
- Through smoking, high blood
pressure etc
- 1) Damage to endothelial lining (artery lining)
