Hypertension
Part of: Cardiovascular disease (CVD)
Also: high blood pressure, arterial hypertension, raised blood pressure
Blood pressure persistently above the threshold at which treatment is advised. It is included here because it is the mechanism through which several indoor exposures reach the heart and the brain, and because it is measured often enough to be studied in households.
Not reviewed by a clinician. This entry describes a disease or a symptom. We are introducing clinical review for pages of this kind; until that reviewer is in place, this page has been written and checked by the Coridum team but not reviewed by a clinician. It is general information and not medical advice. How this library is built is described in How we build this library.
Why it matters indoors
Hypertension sits between exposure and disease. Particles reaching the lung provoke inflammation and affect the autonomic control of the vessels, blood pressure rises, and the rise carries forward into stroke and heart disease. That makes it a useful endpoint for indoor research: it responds within days to weeks, so an intervention can be tested without waiting for the disease.
Two literatures meet here. Household studies of solid fuel find higher pressures and more diagnosed hypertension where cooking is done indoors on an open flame, with the association growing with the number of years exposed. Filtration trials take the opposite approach and ask whether removing particles lowers pressure over weeks; the reductions reported are small, in the range of a few millimetres of mercury.
Coridum keeps the diagnosis and the measurement apart: a reading is blood pressure, a diagnosis is this page.

Each row is one Finding — a sentence as printed in one study, recorded with its page in the Coridum Knowledge Base. Follow the Finding number for the exact wording and the citation. Checked says who verified the row: machine means every automatic check passed and the surrounding text was read; person means someone read the sentence in the document. Rows are re-checked by a person over time. The studies are curated in the Coridum Knowledge Base; the reading of them together is a Claim, shown separately.
