Hypertension Guidelines 2014

HypertensionHypertension is the most common

condition in primary care.

1 in 3 patients have hypertension according to NHLBI

Risk factor for MI, CVA, ARF, death

Hypertension

CaseA 58 year old African-American woman with

diabetes and dyslipidemia has a BP of 158/94 confirmed on several office visits.

Other than obesity, the exam is normal. Labs show normal renal function, well-

controlled lipids on atorvastatin and well-controlled diabetes on metformin. Urine

micro-albumin is mildly elevated.

Case Question 1What goal BP is most appropriate for this

patient?.1<150/90 mmHg.2<130/80 mmHg.3<140/90 mmHg.4<140/80 mmHg.5<140/85 mmHg

Case Question 2What is the drug of choice to start?

Definitions and classification of office BP levels (mmHg)*

Category Systolic Diastolic

Optimal >120 and >80

Normal 120–129 and/or 80–84

High normal 130–139 and/or 85–89

Grade 1 hypertension 140–159 and/or 90–99

Grade 2 hypertension 160–179 and/or 100–109

Grade 3 hypertension ≥180 and/or ≥110

Isolated systolic hypertension ≥140 and >90

* The blood pressure (BP) category is defined by the highest level of BP, whether systolic or diastolic. Isolated systolic hypertension should be graded 1, 2, or 3 according to systolic BP values in the ranges indicated.

Management of High Blood Pressure in Adults

JNC 8: Hypertension Management

Questions Guiding ReviewIn adults with HTN:

.1Does initiating antihypertensive pharmacologic therapy at specific BP thresholds improve health outcomes?

.2Does treatment with antihypertensive pharmacologic therapy to a specified goal lead to improvements in health outcomes?

.3Do various antihypertensive drugs or drug classes differ in comparative benefits and

harms on specific health outcomes?

Blood pressure goals in hypertensive patients

SBP, systolic blood pressure; CV, cardiovascular; TIA, transient ischaemic attack; CHD, coronary heart disease; CKD, chronic kidney disease;DBP, diastolic blood pressure.

Recommendations

SBP goal for “most”•Patients at low–moderate CV risk•Patients with diabetes•Consider with previous stroke or TIA•Consider with CHD•Consider with diabetic or non-diabetic CKD

<140 mmHg

SBP goal for elderly•Ages >80 years•Initial SBP ≥160 mmHg

140-150 mmHg

SBP goal for fit elderlyAged >80 years

<140 mmHg

SBP goal for elderly >80 years with SBP•≥160 mmHg

140-150 mmHg

DBP goal for “most” <90 mmHg

DB goal for patients with diabetes <85 mmHg

BP goal in the elderly




Recommendations Additonal considerations

Mandatory: initiate drug treatment in patients with SBP ≥160 mmHg

• Strongly recommended: start drug treatment when SBP ≥140 mmHg

SBP goals for patients with diabetes: <140 mmHg

DBP goals for patients with diabetes: <85 mmHg

All hypertension treatment agents are recommended and may be used in patients with diabetes

• RAS blockers may be preferred• Especially in presence of preoteinuria or

microalbuminuria

Choice of hypertension treatment must take comorbidities into account

Coadministration of RAS blockers not recommended

• Avoid in patients with diabetes

Hypertension treatment for people with diabetes

SBP, systolic blood pressure; DBP, diastolic blood pressure; RAS, renin–angiotensin system.




Recommendations Additonal considerations

Consider lowering SBP to <140 mmHg

Consider SBP >130 mmHg with overt proteinuria • Monitor changes in eGFR

RAS blockers more effective to reduce albuminuria than other agents

• Indicated in presence of microalbuminuria or overt proteinuria

Combination therapy usually required to reach BP goals

• Combine RAS blockers with other agents

Combination of two RAS blockers • Not recommended

Aldosterone antagonist not recommended in CKD

• Especially in combination with a RAS blocker• Risk of excessive reduction in renal function,

hyperkalemia

Hypertension treatment for people with nephropathy

SBP, systolic blood pressure; CKD, chronic kidney disease; eGFR, estimated glomerular filtration rate; RAS, renin–angiotensin system.

Lifestyle changes for hypertensive patients

* Unless contraindicated. BMI, body mass index.

Recommendations to reduce BP and/or CV risk factors

Salt intake Restrict 5-6 g/day

Moderate alcohol intake Limit to 20-30 g/day men,10-20 g/day women

Increase vegetable, fruit, low-fat dairy intake

BMI goal 25 kg/m2

Waist circumference goal Men: >102 cm (40 in.)*Women: >88 cm (34 in.)*

Exercise goals ≥30 min/day, 5-7 days/week(moderate, dynamic exercise)

Quit smoking
