 Hypertension is the most common condition in primary care.  1 in 3 patients have hypertension according to NHLBI  Risk factor for MI, CVA, ARF, death

 National Institute for Health and Clinical Excellence (NICE), 2011  Kidney Disease: Improving Global Outcome (KDIGO), 2012  European Society of Hypertension/European Society of Cardiology, (ESH/ESC), 2013  American Diabetes Association (ADA), 2014  American Society of Hypertension and the International Society of Hypertension (ASH/ISH), 2014  Eighth Joint National Committee (JNC8), 2013

 Limited to RCT’s ◦ Hypertensive adults > 18 years old ◦ Sample size > 100 ◦ Follow-up > 1 year ◦ Reported effect of treatment on important health outcomes (mortality, MI, HF, CVA, ESRD)  January 1966 to December 2009 ◦ Separate criteria used of RCT’s published after December 2009

 RCT’s December 2009 – August Major study in hypertension  ACCORD, NEJM > 2,000 participants 3.Multicentered 4.Met all other inclusion/exclusion criteria

 Excluded sample size < 100 and f/up period < 1 year  Only included randomized, controlled trials rated as good or fair  Only included studies reporting effects of interventions on: ◦ MI ◦ Stroke ◦ ESRD, doubling of Scr, or halving of GFR ◦ Heart failure (HF) or hospitalization for HF ◦ Coronary revascularization or other revascularization ◦ Mortality (Overall mortality, CVD-related mortality, CKD- related mortality)

A – Strong evidence B – Moderate evidence C – Weak evidence D – Against E – Expert Opinion N – No recommendation

JNC8: Strength of Recommendation GradeStrength of Recommendation A Strong: High certainty net benefit is substantial B Moderate Moderate certainty net benefit is moderate to substantial, or High certainty that net benefit is moderate C Weak: At least moderate certainty of small net benefit E Expert Opinion Insufficient evidence, or Evidence is unclear or conflicting Further research is recommended in this area

 In adults with HTN, does initiating antihypertensive pharmacologic therapy at specific BP thresholds improve health outcomes?  In adults with HTN, does treatment with antihypertensive pharmacologic therapy to a specified BP goal lead to improvements in health outcomes?  In adults with HTN, do various antihypertensive drugs or drug classes differ in comparative benefits and harms on specific health outcomes?

 Age > 60 yo ◦ Systolic:  Threshold > 150 mmHg  Goal < 150 mmHg  LOE: Grade A ◦ Diastolic:  Threshold > 90 mmHg  Goal < 90 mmHg  LOE: Grade A

 Age < 60 yo ◦ Systolic:  Threshold > 140 mmHg  Goal < 140 mmHg  LOE: Grade E ◦ Diastolic:  Threshold > 90 mmHg  Goal < 90 mmHg  LOE: Grade A for ages 40-59; Grade E for ages 18-39

 Age > 18 yo with CKD or DM ◦ JNC 7: < 130/80 (MDRD NEJM 1994) ◦ Systolic:  Threshold > 140 mmHg  Goal < 140 mmHg  LOE: Grade E ◦ Diastolic:  Threshold > 90 mmHg  Goal < 90 mmHg  LOE: Grade E

 Nonblack, including DM ◦ Thiazide diuretic, CCB, ACEI, ARB  LOE: Grade B  Black, including DM ◦ Thiazide diuretic, CCB  LOE: Grade B (Grade C for diabetics)

 Age > 18 yo with CKD and HTN (regardless of race or diabetes) ◦ Initial (or add-on) therapy should include an ACEI or ARB to improve kidney outcomes  LOE: Grade B ◦ Blacks w/ or w/o proteinuria  ACEI or ARB as initial therapy (LOE: Grade E) ◦ No evidence for RAS-blockers > 75 yo  Diuretic is an option for initial therapy

 If goal BP not met after 1 month of treatment: ◦ Increase dose of initial drug, or ◦ Add a second drug (Thiazide, CCB, ACEi, or ARB)  If goal BP not met with 2 medications: ◦ Add and titrate a third medication (Thiazide, CCB, ACEi, or ARB) ◦ Do not use ACE and ARB together  Other classes may be used in the following scenarios: ◦ Goal BP not met with 3 medications ◦ Contraindication to thiazide, ACE/ARB, or CCB

 Titrate to max dose, then add a second drug  Add a second drug before achieving max dose of the initial drug  Start with 2 drugs at the same time ◦ If SBP ≥ 160mmHg and/or DBP ≥ 100 mmHg ◦ If SBP ≥ 20mmHg above goal and/or DBP ≥ 10mmHg above goal ***Consider scheduling follow-up with the Enhanced Care Clinic for titration of BP Meds
