Heart health

Evidence checks about cardiovascular headlines, cholesterol, blood pressure, stroke, statins, heart attacks and risk-factor claims.

What to watch for

Common ways headlines can go too far

  • Risk-factor changes treated as proven outcome benefit
  • Relative risk reported without baseline risk
  • Associations framed as direct prevention advice

Heart-health headlines often turn risk-factor changes, relative-risk figures or observational associations into stronger prevention advice than the evidence supports.

Common hype patterns

  • Changes in cholesterol, blood pressure or biomarkers framed as proven clinical benefit.
  • Relative risk reported without baseline or absolute-risk context.
  • Observational associations presented as direct prevention advice.
  • Early device, AI or drug signals described before patient outcomes are shown.

Questions to ask before trusting the headline

  • Was the claim tested in people, or only in cells, animals or models?
  • Is the outcome something patients notice, or only a surrogate marker?
  • Does the headline distinguish association from causation?
  • Are absolute risks, comparators and uncertainty shown clearly?
  • Would the finding change real-world behaviour, or is it mainly hypothesis-generating?

deHype.io separates the public claim from the underlying evidence. The aim is not to dismiss early science, but to show whether the headline has kept the finding in proportion.
