Diagnostic & Clinical Standards

Authoritative clinical thresholds and screening guidelines from major medical bodies.

Stage 2 Hypertension

ACC/AHA2017

Stage 2 hypertension is classified when the systolic (top number) is 140 mmHg or higher, or the diastolic (bottom number) is 90 mmHg or higher.

Stage 2 Hypertension (Systolic)≥ 140mmHg

Systolic blood pressure meets the Stage 2 hypertension threshold.

Stage 2 Hypertension (Diastolic)≥ 90mmHg

Diastolic blood pressure meets the Stage 2 hypertension threshold.

Normal Blood Pressure

ACC/AHA2017

Blood pressure is considered normal when the systolic (top number) is less than 120 mmHg and the diastolic (bottom number) is less than 80 mmHg.

Normal (Systolic)< 120mmHg

Systolic blood pressure is within the normal range.

Normal (Diastolic)< 80mmHg

Diastolic blood pressure is within the normal range.

Elevated Blood Pressure

ACC/AHA2017

Blood pressure is classified as elevated when the systolic (top number) is between 120 and 129 mmHg and the diastolic (bottom number) is still less than 80 mmHg.

Elevated (Systolic)120 – 129mmHg

Systolic blood pressure is in the elevated range.

Elevated (Diastolic must be < 80)< 80mmHg

Diastolic blood pressure must remain below 80 mmHg for the elevated category (otherwise classified as hypertension).

Stage 1 Hypertension

ACC/AHA2017

Stage 1 hypertension is classified when the systolic (top number) is 130-139 mmHg or the diastolic (bottom number) is 80-89 mmHg.

Stage 1 Hypertension (Systolic)130 – 139mmHg

Systolic blood pressure meets the Stage 1 hypertension threshold.

Stage 1 Hypertension (Diastolic)80 – 89mmHg

Diastolic blood pressure meets the Stage 1 hypertension threshold.

Hypertensive Crisis

ACC/AHA2017

A hypertensive crisis occurs when blood pressure readings exceed 180/120 mmHg. This requires immediate medical attention, especially if accompanied by symptoms such as chest pain, shortness of breath, or neurological changes.

Hypertensive Crisis (Systolic)

> 180mmHg

Hypertensive Crisis (Diastolic)

> 120mmHg

Hypertensive Crisis (Systolic)> 180mmHg

Systolic blood pressure exceeds 180 mmHg. Requires immediate medical evaluation.

Hypertensive Crisis (Diastolic)> 120mmHg

Diastolic blood pressure exceeds 120 mmHg. Requires immediate medical evaluation.
