Normal 120-129 and/or 80–84
High normal 130-139 and/or 85–89
Grade 1 hypertension 140-159 and/or 90-99

Definitions and classification of office BP levels (mmHg)
The blood pressure (BP) category is defined by the highest level of BP, whethersystolic or diastolic. Isolated systolic hypertension should be graded 1, 2, or 3according to systolic BP values in the ranges indicated
Factors—other than office BP—influencingprognosis; used for stratification of total CV risk
Risk Factors• Male sex• Age (men ≥55 years; women ≥65
years)• Smoking• DyslipidaemiaTC > 190 mg/dL, and/orLDL >115 mg/dL, and/orHDL: men <40 mg/dL, women < 46
mg/dL, and/orTriglycerides >150 mg/dL

• Abdominal obesity (waist circumference: men ≥102
cm;women ≥88 cm) • Family history of premature
CVD (men aged <55 years; women aged <65 years)

Asymptomatic organ damage
• Pulse pressure (in the elderly) ≥60 mmHg
• ECG :LVH (Sokolow–Lyon index >3.5 mV;RaVL >1.1 mV; Cornell voltage duration product >244 mV x ms), or
• Echo: LVH [LVM index: men >115 g/m²;women >95 g/m² (BSA)]
• Carotid wall thickening (IMT >0.9 mm) or plaque
• Carotid–femoral PWV >10 m/s• Ankle-brachial index <0.9 • CKD with eGFR 30–60
ml/min/1.73 m² (BSA)• Microalbuminuria (30–300
mg/24 h), or albumin–creatinine ratio 30–300 mg/g; (preferentially on morning spot urine)
Factors—other than office BP—influencingprognosis; used for stratification of total CV risk
Diabetes mellitus
• Fasting plasma glucose ≥126 mg/dL on two repeated measurements, and/or
• HbA1c >7% , and/or• Post-load plasma glucose >198 mg/dL
Factors—other than office BP—influencingprognosis; used for stratification of total CV riskEstablished CV or renal Disease
• Cerebrovascular disease: stroke; TIA• CHD:MI; angina; revascularization with PCI or CABG• HF, including HF with preserved EF• Symptomatic lower extremities PAD • CKD with eGFR <30 mL/min/1.73m²(BSA); proteinuria (>300 mg/24 h).• Advanced retinopathy: haemorrhages or exudates,

Total CV RISK
Stratification of total CV risk in categories of low, moderate, high and very high risk according to SBP and DBP and prevalence of RFs,Asymptomatic OD,diabetes,CKD stage or symptomatic CVD.
Initiation of lifestyle changes and antihypertensive drug treatment. Targets of treatment are also indicated(<140/90). (in patients with diabetes, the optimal DBP target is between 80 and 85 mmHg.)

Diuretics (thiazides,chlorthalidone and indapamide), beta-blockers,calcium antagonists, ACE inhibitors, and angiotensin receptor blockers are all suitable and recommended for the initiation and maintenance of antihypertensive treatment, either as monotherapy or in some combinations with each other

The Joint National Committee (JNC )
JNC 8 Has Finally Arrived
This JNC 8 guideline has not redefined high BP, and considers the 140/90 mm Hg definition from
JNC 7 reasonable.
Category SBP (mm Hg) DBP (mm Hg)
Normal < 120 < 80
Pre – hypertension 120-139 80-90
Hypertension
Stage 1 140 – 159 90 – 99
Stage 2 160 and above 100 and above
JNC 7 Compelling Indications
† ACEI, angiotensin converting enzyme inhibitor; ARB, angiotensin receptor blocker;Aldo ANT, aldosterone antagonist; BB, beta-blocker; CCB, calcium channel blocker.
Questions guiding the JNC 8 review
This hypertension guideline focuses on 3 questions related to high blood pressure (BP) management. They address thresholds, goals for pharmacologic treatment, and whether particular antihypertensive drugs or drug classes improve important health outcomes compared to others.
1.In adults with hypertension, does initiating antihypertensive pharmacologic therapy at specific BP thresholds improve health outcomes?
2.In adults with hypertension, does treatment with antihypertensive pharmacologic therapy to a specified BP goal lead to improvements in health outcomes?
3.In adults with hypertension, do various antihypertensive drugs or drug classes differ in comparative benefits and harms on specific health outcomes?
The answers to these three questions are reflected in 9 recommendations
Recommendation 1 (Strong recommendation)
Recommendation 2 (Strong recommendation)
