Hypertension Flashcards
What is optimal BP ?
<120/<80
What is normal BP ?
120-129/80-84
What is high normal BP ?
130-139/85-89
What is the BP in grade 01 HTN ?
140-159/90-99
What is the BP in grade 02 HTN ?
160-179/100-109
What is the BP in grade 03 HTN ?
greater than or equal to 180/ greater than or equal to 110
What is isolated systolic HTN?
≥ 140 / <90
What is isolated diastolic HTN ?
<140 /≥ 90
When should BP screening repeated in patients with optimal BP
( <120/80)?
Every 5 year.
When should BP screening repeated in patients with normal BP (120-129/80-84) ?
Repeat BP at least every 3 year.
When should BP screening repeated in patients with High normal BP (130-139/85-89) ?
Repeat BP at least annually + consider masked HNT ergo do HBPM and ABPM.
What should be the approach to clinical HTN (≥ 140 / <90)
Use repeated clinic visits or HBPM / ABPM to confirm the Dx.
What is the utility of Systematic Coronary Risk Evaluation (SCORE2 or SCORE2-OP)?
SCORE2 can be used to calculate 10-year risk of fatal & non-fatal CVD event in apparently healthy individuals ( age 40-69) and SCORE2-OP in people >70 years.
What are the parameters for calculating 10 year risk for fatal or non-fatal CVD in HTN patients ?
- Gender
- Age
- Smoking
- Systolic BP value
- Non-HDL cholesterol level
What are the parameters of very high 10- year CVD risk classification ?
Anyone of the following:
* Hx of Clinical CVD events.
* Unequivocally documented CVD on imaging such as ≥ 50% stenosis on angio or US.
* T2DM with end organ damage.
* Sever CKD: eGFR< 30 ml/min.
* A calculated 10 year SCORE ≥ 10
What are the parameters of high 10- year CVD risk classification ?
Anyone of the following:
* Marked elevation of a single risk factor such as cholesterol >80 mMol/L or familial hypercholesterolimia or grade 3 HTN.
* T2DM
* Hypertensive LVH
* Moderate CKD: eGFR b/w 30-59/Ml/min.
* A calculated 10 year score of 5-10%
What are the parameters of moderate 10- year CVD risk classification ?
- A calculated 10 year score of 1 to < 5%.
- Grade 02 HTN
What are the parameters of Low 10- year CVD risk classification ?
A calculated 10 years score of <1%
What is the initial management of high normal BP ?
- life style change.
- Consider drug Tx in very high risk patients with CVD especially CAD.
What is the initial management of Grade 01 HTN?
- life style advice.
- Immediate drug therapy in high or very high risk patients with CVD, renal disease or HMOD.
- After 3 to 6 months lifestyle intervention, if BP is not controlled drug therapy in moderate risk patients with CVD, renal disease or HMOD.
What is the initial management of grade 02 and 03 HTN?
Life style advice + immediate drug therapy with an aim to control BP within 3 months.
What should be the consideration for drug therapy in very high risk patients with high- normal SBP ( 130-140 mmHg)?
- In patients b/w the age of 18 and 79 drug therapy should be considered, if they have HTN, T2DM, CKD, CVD, stroke/ TIA and their BP ≥ 140/ ≥90
- In people ≥ 80 years the same risk factors with an SBP ≥ 160 should qualify for drug therapy.
What are the parameters of lifestyle change in HTN management ?
- Reduce dietary sodium to 2g/day
- Reduce alcohol to 14 units/wk for men and 8 units/wk for women.
- Adopt a healthy balanced diet.
*Weight reduction in obese - Regular physical activity for 30min of moderate-intensity aerobic exercise 5-7/ week and Smoking cessation.
What are the medical management steps in uncomplicated HTN?
- Step-01: Initiate therapy with ACEI or ARB+ CCB or diuretic and consider mono therapy in low risk grade 01 HTN( <150mmHg) and in frail older patients >80 years.
- Step02: ACEI or ARB + CCB + diuretics.
- Step 03: If resistant HTN add spironolactone 25-50 mg OD or other diuretics or beta or alpha blockers.
- Add beta blockers in any of these steps, if there are other co-morbidities and refer to a specialist centre for further evaluation.
