Evidence‑Based Hypertension Classification, Diagnosis, and Management

Blood Pressure Classification

The American College of Cardiology defines four BP categories: normal < 120/80 mm Hg, elevated 120‑129/<80 mm Hg, stage 1 hypertension 130‑139/80‑89 mm Hg, and stage 2 hypertension ≥ 140/≥ 90 mm Hg. 1
The European Society of Cardiology (2024) uses the same numeric thresholds but labels them “non‑elevated,” “elevated,” and “hypertension” for therapeutic decision‑making. 2

Diagnosis requires repeated office BP measurements on at least two separate visits, with three readings taken 1–2 minutes apart at each visit; if the first two readings differ by >10 mm Hg, additional measurements are needed. 3
When feasible, confirmation with ambulatory blood pressure monitoring (ABPM) or home blood pressure monitoring (HBPM) is recommended to improve diagnostic accuracy. 3
Cuff‑less devices (e.g., smartwatches) should not be relied upon for diagnosis until they demonstrate sufficient precision and reliability. 1

Adults with normal BP should continue healthy lifestyle practices (e.g., balanced diet, regular activity) and no pharmacologic therapy is indicated. 1

Lifestyle modification for all patients is recommended, including weight management, DASH‑style diet, sodium reduction, increased dietary potassium, moderate physical activity, stress management, and limiting alcohol intake. 1
Pharmacologic therapy is not initiated unless the individual has additional high‑risk cardiovascular factors. 1

Lifestyle modification should be started immediately for every patient. 1
Medication initiation is advised without delay for patients with any of the following: established cardiovascular disease, prior stroke, diabetes mellitus, chronic kidney disease, or a 10‑year predicted cardiovascular risk ≥ 7.5 %. 1
For patients with a 10‑year risk < 7.5 %, lifestyle changes are trialed for 3–6 months; if BP remains ≥ 130/80 mm Hg after this period, antihypertensive medication should be started. 1

Both lifestyle modification and antihypertensive medication should be initiated concurrently at diagnosis. 1
The preferred initial pharmacologic strategy is a fixed‑dose single‑pill combination containing two first‑line agents from different drug classes, which improves adherence and accelerates BP control. 1

The overarching treatment goal for all adults is BP < 130/80 mm Hg. 1
European guidelines suggest targeting systolic BP 120‑129 mm Hg when tolerated. 2
For older adults (≥ 65 years) with diabetes, a systolic target of 130‑139 mm Hg is recommended. 2

Severe hypertension (> 180/120 mm Hg) without acute target‑organ damage should be managed in the outpatient setting with timely initiation, reinstitution, or intensification of oral antihypertensive agents. 1
For BP 160‑179/100‑109 mm Hg, the elevated reading should be confirmed promptly (within 1 month), preferably using HBPM or ABPM. 3
BP ≥ 180/110 mm Hg warrants urgent evaluation to exclude a hypertensive emergency. 3
In pregnancy, a systolic BP ≥ 170 mm Hg or diastolic BP ≥ 110 mm Hg constitutes an emergency requiring hospital admission. 2

A multidisciplinary team approach (including physicians, pharmacists, nurse practitioners, nurses, physician assistants, dietitians, and community health workers) effectively reduces barriers to hypertension control. 1
Combining home BP monitoring with frequent, protocol‑driven team interactions improves control rates across patient populations. 1
