Hypertension Flashcards
Hypertension?
Systolic >140 mm Hg and/or diastolic >90 mm Hg measured on 3 separate occasions.
Hypertension systole and diastole?
Hypertension malignant hypertension?
BP > 200/130mm Hg
Hypertension risk factors (5)?
Primary or idiopathic hypertension, responsible for >90% of cases.
Secondary Renal
Secondary endocrine
Secondary cardiovascular
Secondary to pregnancy.
Hypertension risk factors secondary renal (5)?
renal artery stenosis,
chronic glomerulonephritis,
chronic pyelonephritis,
polycystic kidney disease,
chronic renal failure.
Hypertension risk factors secondary endocrine (8)?
DM,
hyperthyroidism,
cushings syndrome,
Conns syndrome,
hyperparathyroidism,
phaeochromocytoma,
congenital adrenal hyperplasia,
acromegaly.
Hypertension risk factors secondary cardiovascular (2)?
coarctation of the aorta,
increased intravascular volume.
Hypertension risk factors secondary to drugs (3)?
sympathomimetics,
corticosteroids,
COCP.
Hypertension epidemiology?
very common
10-20% of western adults
Hypertension symptoms?
Often asymptomatic, but symptoms of cause or complications.
Symptoms of malignant hypertension; scotomas, blurred vision, headache, seizures, nausea and vomiting, acute heart failure
Hypertension signs?
Radiofemoral delay = coarctation of the aorta distal to the left subclavian artery.
Renal artery bruit = renal artery stenosis. (swishing sound)
Fundoscopy to detect hypertensive retinopathy.
Hypertension investigations (3)?
bloods (U&Es, glucose, lipids)
urine dipstick (blood and protein)
ECG (may show left ventricular hypertrophy or ischaemia)
Hypertension management conservative (4)?
stop smoking,
lose weight,
reduce alcohol intake,
reduce dietary sodium.
Hypertension management medical?
for systolic >160mm Hg or diastolic >100mm Hg;
ACE inhibitors or angiotensin receptor blockers (for >55, DM, heart failure, left ventricle dysfunction),
CCBs (>55, black),
Beta blockers, alpha blockers (4th line treatment).
For severe hypertension management; atenolol and nifedipine.
Hypertension management for acute malignant hypertension?
IV beta blocker, labetolol, hydralazine sodium nitroprusside.
