2 The 8 th Joint National Committee Guidelines (2013) A. Joint National Committee-6 (1997) Classification of Blood Pressure for Adults Aged 18 Years & Older Category Systolic (mm Hg) Diastolic (mm Hg) rmal < 130 < 85 High rmal Hypertension Stage 1 (mild) Stage 2 (moderate) Stage 3 (severe) Stage 4 (very severe) > 210 > 120 B. Joint National Committee-7 (2003) Table 2. Changes in blood pressure classification JNC 6 Category SBP/DBP Optimal <120/80 rmal /80 84 Borderline /85 89 Hypertension >140/90 STAGE /90 99 JNC 7 Category rmal Prehypertension Hypertension STAGE 1 STAGE 2 STAGE / >180/110 STAGE 2 C. Joint National Committee-8 (2013) Patients > 60 years old, initiate pharm. tx at SBP > 150 OR DBP > 90 Patients < 60 years old, initiate pharm. tx SBP > 140 OR DBP > 90. Patients > 18 years with diabetes or CKD, initiate pharm. tx at SBP > 140 OR DBP > 90 General non-black population, including those with diabetes, initial pharm. tx should include a thiazide diuretic, CCB, ACE-I or ARB. (te: BB are omitted) General black population, initial treatment should include a thiazide diuretic or a CCB. (te: BB, ACE-I & ARB are omitted) All patients with CKD and HTN, initial treatment should include an ACE-I or an ARB to improve kidney outcomes. In all hypertensive patients, if goal BP is not reached within a month of initiating treatment, increase the dose of the initial drug OR add a second drug from one of these four classes. o If goal BP cannot be reached with two drugs, add and titrate a third drug from the list provided.

3 Figure Hypertension Guideline Management Algorithm Adult aged 18 years with hypertension Implement lifestyle interventions (continue throughout management). Set blood pressure goal and initiate blood pressure lowering-medication based on age, diabetes, and chronic kidney disease (CKD). General population (no diabetes or CKD) Diabetes or CKD present Age 60 years Age <60 years All ages Diabetes present CKD All ages CKD present with or without diabetes SBP <150 mm Hg SBP <140 mm Hg SBP <140 mm Hg SBP <140 mm Hg nblack Black All races Initiate thiazide-type diuretic or ACEI or ARB or CCB, alone or in combination. a Initiate thiazide-type diuretic or CCB, alone or in combination. Initiate ACEI or ARB, alone or in combination with other drug class. a Select a drug treatment titration strategy A. Maximize first medication before adding second or B. Add second medication before reaching maximum dose of first medication or C. Start with 2 medication classes separately or as fixed-dose combination. Reinforce medication and lifestyle adherence. For strategies A and B, add and titrate thiazide-type diuretic or ACEI or ARB or CCB (use medication class not previously selected and avoid combined use of ACEI and ARB). For strategy C, titrate doses of initial medications to maximum. Reinforce medication and lifestyle adherence. Add and titrate thiazide-type diuretic or ACEI or ARB or CCB (use medication class not previously selected and avoid combined use of ACEI and ARB). Reinforce medication and lifestyle adherence. Add additional medication class (eg, β-blocker, aldosterone antagonist, or others) and/or refer to physician with expertise in hypertension management. Continue current treatment and monitoring. b SBP indicates systolic blood pressure; DBP, diastolic blood pressure; ACEI, angiotensin-converting enzyme; ARB, angiotensin receptor blocker; and CCB, calcium channel blocker. a ACEIs and ARBs should not be used in combination. b If blood pressure fails to be maintained at goal, reenter the algorithm where appropriate based on the current individual therapeutic plan. 33 Downloaded From: on 09/13/2018

Reinforce lifestyle and adherence Add a medication class not already selected (i.e. beta blocker, aldosterone antagonist, others) and titrate above medications to max (see back of card) Initial Drugs of Choice for Hypertension ACE inhibitor (ACEI) Angiotensin receptor blocker (ARB) Thiazide diuretic Calcium channel blocker (CCB) Strategy A B C Description Start one drug, titrate to maximum dose, and then add a second drug. Start one drug, then add a second drug before achieving max dose of first Begin 2 drugs at same time, as separate pills or combination pill. Initial combination therapy is recommended if BP is greater than 20/10mm Hg above goal Lifestyle changes: Smoking Cessation Control blood glucose and lipids Diet Eat healthy (i.e., DASH diet) Moderate alcohol consumption Reduce sodium intake to no more than 2,400 mg/day Physical activity Moderate-to-vigorous activity 3-4 days a week averaging 40 min per session. At blood pressure goal? Reinforce lifestyle and adherence Titrate meds to maximum doses, add another med and/or refer to hypertension specialist Continue tx and monitoring Reference: James PA, Ortiz E, et al evidence-based guideline for the management of high blood pressure in adults: (JNC8).
