AHA/ACC Classification

Stage 1 Hypertension

Reading: 128/82 mmHg • Pulse 72 BPM

Systolic ranges from 130–139 OR diastolic ranges from 80–89 mmHg.

Clinical Next Steps:

Consult your physician. Treatment typically begins with lifestyle changes and may include medication based on cardiovascular risk.

Never type blood pressure readings by hand

Point your phone camera at your OMRON®, Beurer®, Braun®, or generic monitor screen. Subra Space AI extracts SYS, DIA & Pulse in 1 second using 100% on-device vision.

How to measure blood pressure correctly:
  • Sit quietly for 5 minutes before pressing start.
  • Keep cuff supported at exact heart level with uncrossed legs.
  • Avoid caffeine, smoking, or exercise within 30 minutes of measuring.

Authoritative Blood Pressure Guidelines

United States & International2017 AHA / ACC

American Heart Association / American College of Cardiology

The 2017 AHA/ACC guidelines redefined high blood pressure, lowering the threshold for Stage 1 Hypertension to 130/80 mmHg to promote earlier intervention through lifestyle modifications.

Deutsche Hochdruckliga (DHL®) & European Society of Cardiology

The European consensus (ESC 2024 and German DHL guidelines) maintains the clinical definition of Hypertension at $\ge$140/90 mmHg for in-office and $\ge$135/85 mmHg for home monitoring (HBPM).
