Hypertension — master index¶
Last curated: 2026-10-26 · status: draft — sweep additions pending independent audit
The condition in five sentences. Hypertension is the world's largest modifiable cause of cardiovascular death, and its defining feature as a research object is that the science is settled far ahead of the delivery: the number of people aged 30–79 living with it doubled between 1990 and 2019 — from 331 million women (95% CrI 306–359) and 317 million men (292–344) to 626 million (584–668) and 652 million (604–698) — while age-standardised prevalence stayed flat, so the growth is demographic rather than a worsening of risk, and only 59% of women and 49% of men with hypertension had ever been diagnosed (NCD-RisC 2021, PMID 34450083). That treatment works is not in doubt: in 344,716 participants from 48 randomised trials, each 5 mm Hg fall in systolic pressure cut major cardiovascular events by about 10%, with no reliable heterogeneity by baseline pressure or prior disease (BPLTTC 2021, PMID 33933205). How far to lower has moved decisively toward a systolic target below 120–130 mm Hg — SPRINT (HR 0.73, 95% CI 0.63–0.86 for the primary composite; PMID 34010531), then ESPRIT and BPROAD overturning the long-standing diabetes exception (PMIDs 38945140, 39555827) — at a benefit–harm ratio where the number needed to treat (58) and the number needed to harm (55) are nearly equal (Guo 2025, PMID 40902616). The most under-appreciated finding in the field is how much hypertension is not primary: biochemically overt primary aldosteronism was present in 11.3% of normotensive people, 21.6% of stage 2 and 22.0% of resistant hypertension, and the aldosterone-renin ratio used to screen for it had poor sensitivity and negative predictive value (Brown 2020, PMID 32449886) — a finding that in 2025 moved the Endocrine Society to suggest screening everyone with hypertension (Adler 2025, PMID 40658480). What has actually moved population control is system redesign, not new molecules: village-doctor-led care raised control from 19.9% to 57.0% in 326 Chinese villages (Sun 2022, PMID 35500594), while US control peaked at 53.8% in 2013–2014 and fell to 43.7% by 2017–2018 (Muntner 2020, PMID 32902588).

The scoping decision that shapes this condition¶
hypertension returns 724,578 PubMed records — by a wide margin the largest literature in this repository. The failure mode here is not thinness but sprawl: hypertension touches almost every other condition already curated, and a page list drawn without borders would silently duplicate four of them.
This condition owns the exposure and its management. It does not own the end-organ diseases.
| Belongs here | Belongs elsewhere |
|---|---|
| Measurement, diagnosis, thresholds, phenotypes (white-coat, masked, nocturnal) | Cardiac end-organ disease — LVH, HFpEF, remodelling → hypertensive-heart-disease |
| Epidemiology and the detection–treatment–control cascade | Stroke, its acute care and secondary prevention → stroke |
| Pathophysiology, genetics, secondary causes | Coronary disease and its management → ischemic-heart-disease |
| Blood-pressure targets, drug and lifestyle therapy, resistant hypertension, devices | Blood-pressure lowering as dementia prevention → vascular-dementia, which already carries SPRINT MIND |
| Pregnancy, special populations, adherence and implementation, hypertensive emergencies | Diabetes management → type-2-diabetes |
The rule held through the build: cross-link, never restate. Where a trial matters to both conditions, each page cites it for its own endpoint and links the other rather than reproducing the analysis.

Reading paths¶
If you have ten minutes. overview.md, then the "Dots not yet connected" table in OPEN-QUESTIONS.md.
If you want to know how low to treat. blood-pressure-targets.md → risk-and-outcomes.md for the J-curve → special-populations.md for the exceptions → guidelines.md for why bodies disagree.
If you distrust the number itself. definition-measurement-and-diagnosis.md → red-flags-and-safety-concerns.md § measurement error. This is the path most likely to change how you read every other page.
If you want the mechanism. pathophysiology.md → genetics-and-monogenic-forms.md → secondary-hypertension.md. The through-line is that every Mendelian form acts on renal salt handling.
If you treat patients whose pressure will not come down. resistant-and-refractory-hypertension.md → secondary-hypertension.md → device-and-interventional-therapy.md.
If you care about population control rather than individual care. epidemiology-and-burden.md → adherence-and-implementation.md → lifestyle-and-dietary-management.md § salt substitution → patient-experience-and-advocacy.md.
If you want the methodological lessons. device-and-interventional-therapy.md (sham control), pharmacological-therapy.md § chronotherapy (a corrected literature), hypertensive-emergencies.md (three observational studies and no trial).

Status and next step¶
The 2026-10-26 sweep added nine bibliography records and edited seven wiki pages. Genetics was demoted from curated to draft; the other six were already draft. Eight untouched pages remain curated. All new content awaits an independent audit; this sweep does not audit itself. The current search manifest is literature/sweeps/2026-10-26.json; earlier manifests remain in the same directory. Searches, access limits and next-sweep priorities are recorded in LOG.md.
