CM hypertension

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.
