Hypertension Flashcards
How is hypertension defined?
> 140/90
What is primary hypertension?
Hypertension with no obvious cause
If someone’s BP in clinic is hypertensive, what is the next investigation to do?
Ambulatory blood pressure monitoring (ABPM)
What is stage 1 hypertension? What is the management
> 140/90 or >135/85 ABPM
Usually just offer lifestyle advice, however, treat if:
- End organ damage
- Established CVS disease, renal disease or diabetes. Or 10 year CVS risk above 20%
End organ damage = hypertensive retinopathy, urine dipstick (proteinuria) or ECG showing LVF or IHD
Classification and management of stage 2 and 3 hypertension?
Stage 2 = >160/100 or >150/95 ABPM
Stage 3 = >180 systolic or >110 diastolic
Discuss the management of hypertension:
1st line: age < 55 = ACE I. Age > 55 or black = Calcium channel blocker
2nd line = A + C. (Ace inhibitor + Calcium Channel blocker)
3rd line = A + C + D (ACE + Calcium channel + diuretic)
NOTE: the use of indapamide is now preferred to bendroflumethiazide when using a thiazide diuretic.
Resistant hypertension: If potassium < 4.5 use spironolactone
If potassium >4.5 use a higher dose thiazide diuretic.
What should be used in women of child bearing age?
Beta blockers (labetalol)
What is first line in diabetics regardless of age?
ACE I
What is the definition of malignant hypertension?
BP > 200/120
What is the classical pathological feature seen in malignant hypertension?
Fibrinoid necrosis.
Clinical features of malignant hypertension?
Headache, nausea, vomiting, visual disturbance.
Papilloedema
Encephalopathy (seizures)
Management of malignant hypertension?
Oral therapy e.g. atenolol
If severe or encephalopathic use IV therapy e.g. IV labetalol/IV nitroprusside.
