Blood Pressure Stage & MAP Calculator (AHA/ACC)
Classify blood pressure into AHA/ACC hypertension stages, calculate Pulse Pressure (PP) and Mean Arterial Pressure (MAP), and assess cardiovascular risks.

Frequently Asked Questions
What are the official AHA/ACC blood pressure stages?
Under American Heart Association guidelines: Normal: < 120 / < 80 mmHg; Elevated: 120–129 / < 80 mmHg; Stage 1 Hypertension: 130–139 or 80–89 mmHg; Stage 2 Hypertension: 140+ or 90+ mmHg; Hypertensive Crisis: > 180 and/or > 120 mmHg (requires immediate medical care).
What is Pulse Pressure (PP) and why does it matter?
Pulse Pressure is the difference between systolic and diastolic pressure (Systolic - Diastolic). A pulse pressure consistently above 60 mmHg in adults over 50 indicates stiffening and hardening of the major arteries, significantly elevating cardiovascular event risk.
What is Mean Arterial Pressure (MAP)?
Mean Arterial Pressure is the average perfusion pressure flowing through your arteries during a complete cardiac cycle: MAP = Diastolic + ⅓(Systolic - Diastolic). Normal MAP is 70 to 100 mmHg to sustain vital organ perfusion.
What causes 'White Coat Hypertension'?
White coat hypertension is temporary blood pressure elevation triggered by acute stress or anxiety when visiting a doctor's office or clinical environment. Home ambulatory blood pressure monitoring over 7 days is recommended to establish true baseline readings.
