Why we write about the heart in plain words

Open a cardiology report and read a sentence like the patient presents with stable angina and uncontrolled dyslipidemia. Nothing in that sentence is difficult for the two people it was written for, and every word of it is a wall for everybody else. Health communication researchers have a number for the cost of that wall, called health literacy, and public agencies spend real budgets on plain language for exactly this reason. This notebook entry explains the choice this magazine made about words, and the rules we hold ourselves to.

Plain is a health decision, not a style

A reader who understands why sodium accumulates across a day of ordinary packaging can act on it. A reader facing uncontrolled dyslipidemia can only feel vaguely scolded. Plain language is not simplification of the facts; it is simplification of the path to the facts. The CDC runs whole programs on plain language for this reason, and we treat their test as ours: would a tired reader, on a phone, in a hallway, still follow the sentence? When a technical term is unavoidable, and in cardiology it often is, the cardio glossary carries the definition so the article can carry the idea.

How sources are chosen

Every claim in these pages traces to a public institution: the World Health Organization, national public health agencies such as the CDC, the American Heart Association's public education material, and the NIH institutes that publish for general readers. We prefer fact sheets and pages written for the public over press releases, and we date our reading: guidance moves, and a page written against 2026 material will be revisited. What we do not use: forums, content farms, product pages, and studies described by nobody who read them. The editorial policy page holds the full rules.

What will never appear here

Three refusals define this magazine more than anything we publish. No personal medical advice: no interpretation of a reader's numbers, symptoms or medications, ever; that line belongs to clinicians and we keep it visible on every page. No sales: no supplements, gadgets, plans or affiliate links, and the sponsored content page explains how the small amount of commercial work we accept is labeled and separated. No invention: no fake experts, no invented studies, no anonymous anecdotes dressed as experience. The byline is collective, the Everyday Heart editors, because the accountability is collective too.

The glossary grows next

The signature resource of this magazine is the cardio glossary, currently holding a dozen short entries with two long sheets, blood pressure and cholesterol. Next on the bench, in the order readers have asked for them by email: a sheet on resting heart rate, an entry on arrhythmia written with the calm it deserves, and a page untangling heart attack from cardiac arrest, the two events the news permanently confuses. Suggestions go to the contact page, and good ones get a line of credit in the entry they improved.

A word a reader cannot carry home is a word that never left the page.

One more thing the notebook owes its readers: corrections. When we get something wrong, the correction lands on the page itself, dated, with the original error still visible in strikethrough rather than quietly buried. The first dozen pages of this magazine were checked against their sources at publication, and the dates in the footer say when. The heart deserves careful writing, because the reader who needs it most is usually the one having the worst week.
