Cardiovascular disease risk Flashcards
(27 cards)
What is hypertension a risk factor for?
MI
Stroke
HF
CKD
Vascular dementia
How is hypertension diagnosed?
Clinic BP >140/90
Repeat, take lowest
If high, 24-hour ABPM average >135/85
Use standing BP in elderly
Use highest arm
What are the cutoffs for different stages of hypertension?
Stage I: >140/90
Stage 2: >160/100
Stage 3: >180/110
Conversion between home and clinic BP measurements?
Clinic BP is 5/5 higher than home BP
What inter-arm difference in BP is considered an independent risk factor for HTN?
>15 - use highest arm
What did the HYVET trial show?
SBP <150 is associated with 34% RRR in patients >80
Earlier treatment is better
Should contron HTN in elderly
Taking LSBPs
Repeat at 1 and 3 min after standing
Target standing BP
BP targets for control
<80: <140/90
>80: <150/90
(Clinic readings)
When should you initiate pharmacological treatment of BP?
Stage II or above
Stage I with:
- End-organ damage
- QRISK 3 >10%
- CKD
- Diabetes
If <40 - consider 2ry causes
If >80 - caution starting
First line antihypertensive in type 2 diabetics
ACEi or ARB
First line antihypertensive in age <55 and not Afro-Caribbean
ACEi or ARB
First line anti-HTN in age >55 or Afro-Caribbean
Calcium channel blocker
2nd line anti-HTN
Thiazide-like diuretic
e.g. indapamide, xipamide, chlortalidone, bendroflumethiazide
side effects of CCBs
Cranium: Dizziness, drowsiness
Cardiac: Tachycardia, peripheral oedema, palpitations
Bowels: N+V, abdo pain
Skin: Flushing, rash
Spells CCBs!
Side effects of thiazides
Renal: electrolyte disturbance, hypochloraemic alkalosis
leading to
Dizziness
Also
Urticaria
Constipation, diarrhoea
Side effects of ACEi
Alopecia, skin reactions, angioedema
Cough, dry mouth, breathlessness
Ear (tinnitus), vertigo, headache, paresthesia
Monitoring end-organ damage in HTN
Urine dip - proteinuria
Fundoscopy - retinopathy
Ulceration
QRISK 3 cardiovascular risk factors

Erectile dysfunction
Severe mental illness
Atypical antipsychotic
Steroids
Lifestyle recommendations for hypertension
Stop smoking
Reduce alcohol
Avoid excessive caffeine
Weight loss
Increase exercise
Reduce dietary Na, increase K+
Bloods for initiating statin treatment
CK
Blood glucose, HbA1c
Lipid profile
Renal and liver function
Monitor at 3 and 12 months
When to initiate statin treatment?
QRISK >10%
CKD
FHH
T1DM and >40, nephropathy, >10y diabetic
Statin dose for primary prevention
atorvastatin 20mg OD
Plaque-stabilising effect indep of cholesterol lowering
Statin dose for secondary prevention
80mg OD
Cholesterol range indicating FHH
>7.5
