Guidelines

TL;DR — Guideline bodies working from a largely shared evidence base set different numbers, and the disagreements are traceable to three things: what counts as a diagnosis versus a treatment trigger, which measurement method the trial targets were derived from, and how a body weighs population-level harm against individual-level benefit. The definitional split is the most visible: 2025 AHA/ACC and 2025 Hypertension Canada define hypertension at ≥130/80 mm Hg (Writing Committee 2025, PMID 40811516; Goupil 2025, PMID 40419299), while 2023 ESH, 2024 ESC, 2024 Chinese and 2021 WHO keep ≥140/90 (Mancia 2023, PMID 37345492; McEvoy 2024, PMID 39210715; Liu 2025, PMID 39762483; Al-Makki 2022, PMID 34775787). Applying the lower definition to US survey data raised hypertension prevalence from 31.9% to 45.6% but the proportion recommended drug therapy by only 1.9 percentage points (Muntner 2018, PMID 29133599) — the definitional gap is therefore mostly a labelling gap, not a prescribing gap. On treatment targets the convergence is real and recent: most current documents now aim below 130/80 mm Hg where tolerated. The synthesis of what these documents recommend lives here; the document catalogue with supersession chains lives in literature/guidelines/REGISTRY.md.

Where the major documents stand

Body / year Diagnostic threshold Treatment target Out-of-office measurement Notable position
2025 AHA/ACC (PMID 40811516; JACC PMID 40815242; Circulation PMID 40811497) ≥130/80 <130/80 for most Recommended for confirmation Retires and replaces the 2017 document; risk-informed treatment decisions in stage 1

NICE NG136 (UK; updated 2026) Clinic ≥140/90 and daytime ABPM/HBPM ≥135/85 Clinic <140/90 if age <80; <150/90 if age ≥80; corresponding ABPM/HBPM <135/85 and <145/85 Required for diagnostic confirmation Primary recommendations retrieved at audit: NICE — “Hypertension in adults: diagnosis and management”, https://www.nice.org.uk/guidance/ng136/chapter/recommendations, accessed 2026-09-01; indexed summaries (Jones 2020, PMID 32001477; McCormack 2012, PMID 22429432; NG136 record PMID 31577399)

The four substantive disagreements

1. Where diagnosis begins. The 130/80 versus 140/90 split is about labelling, not mostly about drugs: applying 2017 ACC/AHA criteria to NHANES 2011–2014 raised prevalence 13.7 percentage points while raising the drug-recommended proportion 1.9 points, because the newly labelled group is largely recommended lifestyle intervention alone; among those already on treatment, however, the proportion above goal rose from 39.0% to 53.4% (Muntner 2018, PMID 29133599). The counter-argument is that labelling has costs — anxiety, insurance and employment consequences, and therapeutic inertia when a large low-risk group is nominally "uncontrolled". The ESC's response was to create an intermediate "elevated BP" category rather than move the diagnostic line (McEvoy 2024, PMID 39210715).

2. How low to treat. Documents have converged toward <130/80 mm Hg, but from different reasoning. The 2024 ESC specifies 120–129 systolic where tolerated — closer to SPRINT's arm than to a conventional target — while ESH prefers a staged approach beginning at <140/90 (McEvoy 2024, PMID 39210715; Mancia 2023, PMID 37345492). The BPLTTC age-stratified analysis explicitly recommends removing age-based thresholds (BPLTTC 2021, PMID 34461040), which no guideline has fully done. See blood-pressure targets.

3. Which measurement. SPRINT's target was attained by unattended automated office measurement, which reads lower than conventional attended office readings by a heterogeneous amount (Andreadis 2019, PMID 31290085). KDIGO's <120 recommendation is explicit that it applies to standardised office readings and devotes a chapter to measurement precisely for this reason (KDIGO 2021, PMID 33637192; Cheung 2021, PMID 33637203). NICE goes furthest in the opposite direction, requiring ambulatory or home confirmation before a diagnosis is made at all (Jones 2020, PMID 32001477). The 2024 Chinese guidelines are the first major document to admit validated smart wearables for screening and monitoring (Liu 2025, PMID 39762483) — a position not shared by bodies that have reviewed cuffless validation evidence (Stergiou 2023, PMID 37303198).

4. Resource stratification. ISH's essential-versus-optimal two-tier structure and WHO's treatment-focused document are written for settings where the constraint is delivery, not knowledge (Unger 2020, PMID 32370572; Al-Makki 2022, PMID 34775787). Economic modelling in 24 low- and middle-income countries found that in the lowest-income settings, net economic benefit was maximised by treating from systolic ≥160 mm Hg rather than ≥140 (Hutchinson 2024, PMID 38626959) — a conclusion no clinical guideline states, and a real tension between clinical and public-health optimisation.

Where guidelines agree

  • Out-of-office measurement should confirm diagnosis before treatment is started (USPSTF 2021, PMID 33904861; NICE via Jones 2020, PMID 32001477; most others).
  • Thiazide-type diuretics, ACE inhibitors or ARBs, and calcium channel blockers are first-line; β-blockers require a compelling indication (Wright 2018, PMID 29667175; Wiysonge 2017, PMID 28107561).
  • Combination therapy, preferably as a single pill, should be started early in most people rather than after sequential monotherapy failure (Webster 2018, PMID 30120478; Chow 2021, PMID 34469767).
  • Lifestyle measures are first-line and continue alongside drugs — the ISH lifestyle position paper, endorsed by the World Hypertension League and ESH, is the fullest statement (Charchar 2024, PMID 37712135).
  • Spironolactone is the fourth-line agent of choice in resistant hypertension (Williams 2015, PMID 26414968).
  • In acute stroke, guidelines converge closely: no routine lowering in acute ischaemic stroke unless systolic ≥220 or diastolic ≥120 (110) mm Hg, then ~15% within 24 hours; <185/110 before thrombolysis or thrombectomy and <180/105 for 24 hours after; rapid but titrated reduction toward ~140 mm Hg in intracerebral haemorrhage; <130/80 long-term after either (Koga 2026, PMID 41514030). See stroke.

Where guidance has not caught up with the evidence

  • Primary aldosteronism screening. The 2025 Endocrine Society guideline suggests screening every person with hypertension (Adler 2025, PMID 40658480), on prevalence data showing biochemically overt disease in 11.3–22.0% across the pressure spectrum (Brown 2020, PMID 32449886). No general hypertension guideline has adopted this. See secondary hypertension.
  • Diabetes targets. Several documents still reflect ACCORD-BP-era caution, which ESPRIT and BPROAD have superseded (Liu 2024, PMID 38945140; Bi 2025, PMID 39555827).
  • Age thresholds. BPLTTC's recommendation to remove age-based thresholds has not been implemented (BPLTTC 2021, PMID 34461040).
  • Inpatient blood pressure. No guideline sets an inpatient target; three large observational studies suggest current practice is harmful (Anderson 2023, PMID 37252732; Rastogi 2021, PMID 33369614; Canales 2025, PMID 39585709). See hypertensive emergencies.
  • Protocol availability. Standardised treatment protocols — the operational core of every successful implementation programme — are unevenly available worldwide and imperfectly aligned with the guidelines they are meant to implement (Satheesh 2024, PMID 38108382).

Reading a guideline critically

Three questions separate substantive disagreement from apparent disagreement: (1) Is the number a diagnostic label or a treatment trigger? (2) By what measurement method was it derived, and does the reader use that method? (3) Was the recommendation set for an individual clinician or for a health system with a fixed budget? Most cross-guideline "conflicts" resolve once these are separated. The genuine residue — how low to treat frail people, whether to screen everyone for primary aldosteronism, whether wearables may diagnose — is small and identifiable.

Open questions

  • Does the lower diagnostic threshold produce net benefit once labelling harms are counted? The 2026-09-01 PubMed and ClinicalTrials.gov searches located modelling and diagnostic-accuracy studies but no trial randomising a hypertension definition and measuring clinical outcomes (Muntner 2018, PMID 29133599).
  • Which guideline body's approach to the measurement-method problem is right — mandate the trial method (KDIGO), mandate out-of-office confirmation (NICE), or leave it implicit (most)? (KDIGO 2021, PMID 33637192; Jones 2020, PMID 32001477)
  • Should validated wearables be admitted for screening, as the 2024 Chinese guidelines do, when the validation literature is heterogeneous and includes retracted reports? (Liu 2025, PMID 39762483; Stergiou 2023, PMID 37303198)
  • Can a single global guideline serve settings whose economically optimal treatment thresholds differ by 20 mm Hg? (Hutchinson 2024, PMID 38626959; Unger 2020, PMID 32370572)
  • How long should it take a guideline to absorb a trial that reverses a major recommendation — and what is the mechanism for doing it faster than the next full revision cycle? (Bi 2025, PMID 39555827; Adler 2025, PMID 40658480)
