Atherosclerosis = saluran darah (arteri) tersumbat oleh lemak dan cholesterol.Ia akan menyebabkan 3 penyakit utama:
- Coronary artery disease: Stable plaques in the heart's arteries cause angina (chest pain on exertion). Sudden plaque rupture and clotting causes heart muscle to die. This is a heart attack, or myocardial infarction.
- Cerebrovascular disease: Ruptured plaques in the brain's arteries causes strokes, with the potential for permanent brain damage. Temporary blockages in an artery can also cause transient ischemic attacks (TIAs), which are warning signs of stroke; however, there is no brain injury.
- Peripheral artery disease: Narrowing in the arteries of the legs caused by plaque. Peripheral artery disease causes poor circulation. This causes pain on walking and poor wound healing. Severe disease may lead to amputations.
