- a Paralytic attack: Chances increase seven-fold. Weak blood vessels could rupture leading to ‘brain haemorrhage’. Hardening of blood vessels (atherosclerosis) can limit blood flow to the brain resulting in a ‘brain infarct.’
- b Hypertensive encephalopathy: Occurs when very high BP coincides with altered level of consciousness, seizures, swelling of the main nerve supply to the eye or raised brain fluid pressure. Causes brain damage.
Progressive narrowing of the tiny blood vessels supplying the retina leads to their rupture, limiting vision. Very high BP can also cause partial/total visual loss due to swelling of the optic nerve.
- a Angina / heart attack: 3-fold increased risk. Coronary blood vessels harden, limiting blood flow to already thickened heart muscle.
- b Heart failure: 6-fold increased risk. Enlargement of the heart muscle from chronically high...
