RECOMMENDATIONS
RECOMMENDATION 1 Gen pop ≥ 60 years
Start at SBP>150 OR DBP>90
Goal SBP<150 AND DBP<90
Strong – Grade A
PS:- If already having lower values + no adverse
effects = continue present Rx Exp Op – Grade E
RECOMMENDATION 2
Gen pop < 60 years
Start at DBP ≥ 90
Goal DBP < 90
Strong – Grade A (30-59 years)
Exp Op – Grade E (18-29 years)
RECOMMENDATION 3
Gen pop < 60 years
Start at SBP ≥ 140
Goal SBP < 140
Exp Op – Grade E
RECOMMENDATION 4
CKD ≥ 18 years
Start at SBP ≥ 140 OR DBP ≥ 90
Goal SBP < 140 and DBP < 90
Exp Op – Grade E
PS:- No evid for BP goal – CKD > 70 years Induvidualize Rx
RECOMMENDATION 5
DM ≥ 18 years
Start at SBP ≥ 140 OR DBP ≥ 90
Goal SBP < 140 AND DBP < 90
Exp Op – Grade E
RECOMMENDATION 6
Gen pop non-black (+/- DM)
Initial drug:- Thiazide diuretic CCB ACEi ARB
Mod Recomm – Grade B
CAVEATS
Only for initial drug choice. Add-on any will do
Specific to thiazide diuretics
Drugs to be adequately dosed
NOT for CAD, HF, CKD
RECOMMENDATION 7
Gen Black pop (+/- DM)
Initial drug:- Thiazide/CCB
Mod Recomm – Grade B (Gen Black)
Weak Recomm – Grade C (Black + DM)
PS:- Diuretic > CCB in preventing HF
RECOMMENDATION 8
Adults CKD (any race, +/- DM)
ACEi/ARB as initial/add-on
Mod Recomm – Grade B
PS – Only improves kidney outcomes
RECOMMENDATION 9
MAIN AIM – attain + maintain goal BP
Not at goal by 1 mth Rx:- ↑ dose initial drug / add-on 2nd drug Continuous assessment and drug adjustment
Use drugs from other classes if:- > 3 drugs needed Contraindic/adverse effect of recomm classes
Exp Op – Grade E
COROLLARIES 1
Assess BP regularly
Evidence based lifestyle and adherence interventions
Adjust Rx till goal attained + maintained
Dose and titration not discussed (no RCTs)
Algorithm suggested – not validated for benefit
COROLLARIES 2
3 Strategies suggested:- Initiate 1 drug – go to max – then add 2nd drug Initiate 1 drug – add 2nd drug before 1st @ max Initiate 2 drugs in single / fixed dose combo
Drugs may be substituted if:- Not effective Adverse effects
