Values?
Optimal - <120/80 Normal -130/85 High normal-140/90 Grade 1 -160/80 Grade 2-180/90 Grade 3->180/90 Isolated systolic htn- >140/<90 Target -140/90 then 130/80
Symptoms of HTN?
usually asymptotic Headache Sweating Palpitation Epitaxis SOB Malignant htn- severe headache visual disturbance,fits,transient LOC
Secondary Causes of HTN?
Lifestyle-diet,lack of exercise Drugs-alchohol, bp increasing drugs,poor adherence Metabolic- obesity Vascular- COA Renal-renal artery stenosis, CKD Endocrine-cons,hypercortisolaemia, phaechromocytoma, acromegaly, hyper/hypo thyroidism Respi- obstructive sleep apnea Neuro-autonomic failure Obstretic- pregnancy
Most common secondary causes
Hyperaldosteronism
Obs sleep apnea
Obesity
How to check the compliance of the drugs?
- morisky medication adherence scale
- Prescription refill rate
- Drug analytical test on plasma or urine
Anti hypertensive drugs
- ACEI/ARB
- CCB
- thiazide like diuretic
- spironolactone
Features of hypertensive retinopathy?
Grade 1- arteriolar thickening, tortuousity, increased reflective ness
Grade 2- grade 1+ AV nipping
Grade3- 2+ evidence of retinal ischemia (flame hemorrhage, cotton wool spots)
Grade 4- 3+ papilloedema
Mx of HTN?
1.lifestyle modifications
DASH diet, salt restriction, weight reduction, exercise, reduce alcohol, stop smoking, high k, asses cardiovascular risk
2. Pharmacological management
Indications-
Consider High norm bp with high cardiovascular risk
Start for grade 1 with high CVR/organ damage / CKD/ no control with lifestyle modifications for 3-6 months
Start for all grade 2 and 3
Irrespective of comorbidities, > 80 y tx threshold is 160/90
Mono therapy indications-
SBP<150 and low risk
High Norma bp with a very high cv risk
Old frail people
- ACEI/ARB + CCB/diuretic
- ACEI/ARB + CCB + diuretic
- Add spironolactone
