Hypertensive Emergencies Bleeding eyes, loss blood in urine, >200/120,
swelling death if not treated Accelerated / Malignant Hypertension Hypertensive Encephalopathy Alteration mental state Hypertensive Intracerebral Hemorrhage Acute Left Ventricular Failure Acute Aortic dissection Severe chest pain, widen mediastinum, CT scan
Severe shortness of breath fr backup of blood in lungs, break wall of aorta Brain: Stroke & TIA
Brain Hypertension ⇒ accelerated atherosclerosis TIA – temporary (<24hrs) occlusion of cerebral blood vessel Ischemic Stroke – occlusion of cerebral blood vessel ⇒ long term loss of function or infarction on neuro imaging Ischaemic/ haemorrhagic stroke - >24hrs / scan brain w infarction ischaemic stroke (no longer TIA) Hypertensive Intracerebral hemorrhage due to spontaneous rupture of small penetrating arteries deep in the brain Sites: basal ganglia (putamen, thalamus), cerebellum, pons Ichaemic – dark + swelling
Haemorrhagic – white on CT scan Eyes: Hypertensive Retinopathy
Eyes Arteriolar narrowing
Papilledema Swelling of optic disc
Blind spots Retinal lesions often scotomata, blurred vision & even blindness Leaking of BV Soft exudates Fr blockage of BV
