Blood Pressure 128 over 59 - what do these values mean?
Yes, mostly. 128/59 is normal by international guidelines. US guidelines are stricter and already call it elevated, so it is worth keeping an eye on. Its lower number is low on its own, though — see below.
- International (ESH)Normal
- US guideline (AHA/ACC)Elevated
- Pulse pressure69 mmHg
- Mean arterial pressure82 mmHg
What to do now
- Small changes keep it from rising: less salt, more vegetables and fruit, daily activity.
- Re-check at least once a year.
The systolic (upper) number decides the category: when the two numbers fall into different categories, the higher one counts. Your lower number of 59 is low on its own (diastolic below 60), and the gap of 69 mmHg between the two numbers is wide — mention it to your doctor, sooner if you feel dizzy or faint.

International and US categories
| Category | Systolic / diastolic (mmHg) | US (AHA/ACC) |
|---|---|---|
| Ideal (optimal) | < 120 and < 80 | Normal |
| Normal | 120–129 and/or 80–84 | Elevated / stage 1 |
| High normal | 130–139 and/or 85–89 | Stage 1 |
| Hypertension stage 1 | 140–159 and/or 90–99 | Stage 2 |
| Hypertension stage 2 | 160–179 and/or 100–109 | Stage 2 |
| Hypertension stage 3 | ≥ 180 and/or ≥ 110 | Stage 2 / severe > 180/120 |
| Low blood pressure | systolic < 90 or diastolic < 60, the other number not raised | Low |
International categories: European Society of Hypertension (ESH) 2023, office readings. Home readings use lower thresholds — hypertension from an average of 135/85. A reading with one raised and one low number counts by the raised one.
Pulse pressure and mean arterial pressure
A pulse pressure of 69 mmHg is wide (above 60). In older adults it usually reflects stiffer arteries. Mean arterial pressure — the average pressure perfusing your organs — is about 82 mmHg, within the typical range of about 70–100.
Measure it right
- No caffeine, exercise or smoking for 30 minutes; empty your bladder.
- Sit with back supported, feet flat, for 5 minutes. Don't talk.
- Upper-arm cuff of the right size on bare skin, arm supported at heart level.
- Two readings a minute apart, morning and evening, for 7 days — use the average.
