The terminology has changed significantly in recent years.
The old term “hypertensive urgency” is being phased out by the American Heart Association and other organizations. The preferred newer terminology is:
- Severe asymptomatic hypertension
or - Markedly elevated blood pressure without target-organ damage
The key modern concept is:
It is NOT the blood pressure number alone that defines emergency.
It is the presence of acute target-organ injury.
Current Hypertension Screening / Classification
According to the 2025 American Heart Association / American College of Cardiology guideline:
Blood Pressure Categories
Category
Systolic
Diastolic
Normal
<120
and <80
Elevated
120–129
and <80
Stage 1 HTN
130–139
or 80–89
Stage 2 HTN
≥140
or ≥90
Current Screening Recommendations
Adults ≥18
Routine BP screening for all adults.
If BP is normal (<120/<80)
Recheck:
- approximately yearly
Elevated BP (120–129/<80)
Repeat:
- within 3–6 months
- lifestyle counseling
Stage 1 HTN (130–139 or 80–89)
Confirm with:
- repeat office measurements
- home BP monitoring
or - ambulatory BP monitoring
Treatment depends partly on cardiovascular risk.
Stage 2 HTN (≥140 or ≥90)
Usually:
- lifestyle changes
- antihypertensive medication
Current Treatment Thresholds (2025 Guideline)
Treat if:
- BP ≥140/90
OR - BP ≥130/80 PLUS elevated cardiovascular risk
Examples:
- diabetes
- CKD
- known ASCVD
- prior stroke
- elevated PREVENT risk score
Goal BP for most adults:
- <130/80
Hypertensive Emergency
Current Definition
Severe hypertension PLUS acute target-organ damage.
Typically:
- SBP ≥180
and/or - DBP ≥120
WITH evidence of acute organ injury.
Examples of Target-Organ Damage
Neurologic
- stroke
- intracranial hemorrhage
- hypertensive encephalopathy
Cardiac
- acute coronary syndrome
- pulmonary edema
- acute heart failure
- aortic dissection
Renal
- acute kidney injury
Ophthalmologic
- papilledema
- retinal hemorrhages
Pregnancy
- eclampsia/preeclampsia
Important Clinical Principle
A BP of:
- 220/130
WITHOUT organ damage
is NOT automatically a hypertensive emergency.
Meanwhile:
- 185/110
WITH pulmonary edema or stroke
IS a hypertensive emergency.
The organ damage matters more than the absolute number.
Current Management of Hypertensive Emergency
Usually:
- ICU admission
- IV antihypertensives
- controlled BP reduction
The modern recommendation is generally:
- lower MAP gradually
- avoid excessive rapid reduction
Typical goal:
- no more than ~25% reduction in first hour unless special condition exists.
Special Cases
Aortic Dissection
More aggressive lowering:
- SBP often targeted <120 rapidly
Acute Ischemic Stroke
BP management depends on:
- thrombolysis candidacy
- stroke type
“Hypertensive Urgency” — What Happened to the Term?
The term is falling out of favor.
Older definition:
- severe BP elevation
- no acute organ damage
Now preferred terminology includes:
- severe asymptomatic hypertension
- asymptomatic markedly elevated BP
- severe hypertension without target-organ damage
Why the Change?
Because “urgency” implied:
- emergency treatment
- IV antihypertensives
- ED transfer
But evidence showed most asymptomatic severe hypertension:
- does NOT benefit from rapid lowering
- often should NOT receive IV therapy
- is usually managed outpatient with medication adjustment
What About “Accelerated Hypertension”?
This is another older term.
Historically:
- “accelerated hypertension”
meant: - severe hypertension
- retinal hemorrhages/exudates
WITHOUT papilledema
And:
- “malignant hypertension”
meant: - severe hypertension
WITH papilledema
Modern practice largely replaces both terms with:
- hypertensive emergency
if acute target-organ damage exists
The older terminology is much less commonly used now.
You may still hear:
- malignant hypertension
- accelerated hypertension
especially from older clinicians or older literature, but contemporary guidelines emphasize:
- hypertensive emergency
vs - severe asymptomatic hypertension.
Practical Correctional Medicine Approach
Usually DOES NOT need ED transfer:
- asymptomatic BP 190/110
- asymptomatic BP 210/120
- no neuro symptoms
- no chest pain
- normal mentation
- no pulmonary edema
These patients often need:
- repeat measurement
- medication restart/intensification
- outpatient follow-up
Usually DOES Need ED Transfer:
Severe BP plus:
- chest pain
- dyspnea
- neuro deficits
- confusion
- papilledema
- pulmonary edema
- AKI
- pregnancy complications
Very Important Correctional Medicine Point
Many incarcerated patients present with:
- anxiety
- withdrawal
- pain
- agitation
All can transiently elevate BP substantially.
Do not reflexively send every asymptomatic BP >180 to the ED.
But also:
- do not miss true end-organ injury.
That distinction is one of the most important correctional medicine skills.
