Overview
Hypertension is high blood pressure requiring confirmation with repeated measurements, assessment for secondary causes and target-organ damage, cardiovascular risk stratification, and individualized treatment.

Assessment Workflow
View More on Disease Algorithm-
1. Take history
Assess BP history, symptoms, drugs and comorbidities.
-
2. Examine patient
Measure BP and assess BMI, organs and pulses.
-
3. hypertension
Repeat office BP or use out-of-office measurement.
-
4. complications
Evaluate secondary causes and target-organ damage.
-
5. Stratify risk
Classify BP stage and total cardiovascular risk.
Diagnosis
Differential Diagnosis
| Differential diagnosis | Key Distinguishing Feature |
|---|---|
| Acromegaly[6] | |
| Aortic coarctation[6] | |
| Chronic kidney disease[6] | |
| Drug-induced hypertension[6] | |
| Obstructive sleep apnea[6] |
Diagnostics: Lab Tests and Imaging
| Test / Assessment | Clinical Purpose |
|---|---|
| Urinalysis and urine ratios | Assess renal disease and albumin or protein loss.[6][9] |
| Renal function tests | Assess eGFR and target-organ damage.[6][9] |
| Fasting glucose or HbA1c | Screen for diabetes and comorbidity.[2][6] |
| Lipid profile | Identify additional cardiovascular risk factors.[6][8] |
| 12-lead ECG | Assess cardiovascular effects and target-organ damage.[6][9] |
Pharmacological Management
| Treatment role | Therapy | Key note |
|---|---|---|
| First-line agents | ACE inhibitors or ARBs | Recommended first-line classes; include in CKD treatment.[1][3][5] |
| First-line agents | Calcium antagonists | One of the recommended first-line antihypertensive classes.[1][3][5] |
| First-line agents | Thiazide diuretics | One of the recommended first-line antihypertensive classes.[1][3][5] |
| Combination therapy | Two separate drug classes | Recommended when BP is ≥140/90 mmHg or >20/10 above target.[3][6] |
| Resistant hypertension | Aldosterone antagonist | Preferred after excluding secondary hypertension.[6] |
Dosage Guidelines
Benazepril
ACE inhibitorsDosage: Initial dose: 10 mg PO 24 hourly. Maintenance dose: 20-40 mg/day PO. Max dose: 40-80 mg/day.
Doxazosin
Alpha-blockersDosage: Regular release: Initial dose: 1 mg PO 24 hourly; may increase at 1-2-week intervals to 2 mg and then 4 mg PO 24 hourly. Max dose: 16 mg/day.
Azilsartan medoxomil
Angiotensin II antagonistsDosage: Initial dose: 40 mg PO 24 hourly. May increase up to 80 mg PO 24 hourly.
Sacubitril/Valsartan
ARNIDosage: 200-400 mg PO 24 hourly.
Non-pharmacological management
- Promote weight reduction and maintenance of healthy body weight.
- Recommend reduced salt intake and a Mediterranean or DASH diet.
- Encourage regular aerobic and resistance exercise.
- Advise smoking cessation and limit alcohol consumption.
- Encourage home BP measurement with validated devices.[5][7][8]
Specialist Referral
Referral Indication: Secondary cause of hypertension is found or suspected.
Suggested Specialist: specialist
Referral Indication: BP goals cannot be achieved despite treatment strategies.
Suggested Specialist: hypertension specialist
Referral Indication: Complicated patients requiring additional consultation.
Suggested Specialist: hypertension specialist
