Blood Pressure Category Reference
Where a reading sits on the ACC/AHA chart — with the home-vs-clinic and single-reading caveats stated.
A single reading rarely means much — pressure swings with stress, caffeine, a full bladder, and the 'white-coat' effect at clinics. Diagnosis rests on averaged readings across days, ideally home measurements taken seated, rested, arm supported. Note Europe/India often still use the older 140/90 hypertension line rather than ACC/AHA's 130/80. Treatment decisions are always a clinician's, with your whole risk picture.
