Hypertensive Urgency Management
For hypertensive urgency (BP >180/120 mmHg without acute end-organ damage), initiate oral antihypertensive therapy and arrange outpatient follow-up within 2-4 weeks—hospital admission and IV medications are not indicated. 1
Immediate Assessment: Confirm This is Truly Hypertensive Urgency
The critical first step is distinguishing urgency from emergency, as management differs completely:
Confirm BP elevation with repeat measurement after the patient has rested for 5-10 minutes 1
Systematically assess for target organ damage through focused examination 1:
- Neurologic: altered mental status, headache with vomiting, visual disturbances, seizures, focal deficits 1
- Cardiac: chest pain, dyspnea suggesting acute MI or pulmonary edema 1
- Vascular: symptoms of aortic dissection (tearing chest/back pain) 1
- Renal: acute kidney injury (check creatinine if available) 1
- Ophthalmologic: fundoscopy for papilledema, hemorrhages, or exudates if feasible 1
If ANY target organ damage is present, this becomes a hypertensive emergency requiring immediate ICU admission and IV therapy 1
Oral Antihypertensive Selection
The choice of oral agent depends on the patient's race and comorbidities:
For Non-Black Patients 1:
- Start with low-dose ACE inhibitor or ARB as first-line therapy 1
- Add a dihydropyridine calcium channel blocker (e.g., amlodipine) if BP remains uncontrolled 1
- Titrate to full doses before adding a third agent 1
- Add thiazide or thiazide-like diuretic as third-line therapy 1
For Black Patients 1:
- Start with combination therapy: ARB plus dihydropyridine calcium channel blocker OR calcium channel blocker plus thiazide/thiazide-like diuretic 1
- Titrate to full doses of the initial combination 1
- Add the missing component (diuretic or ARB/ACEI) as third-line 1
Blood Pressure Reduction Timeline
The key principle is gradual reduction over 24-48 hours, NOT immediate normalization:
- Target BP <130/80 mmHg (or <140/90 mmHg in elderly/frail patients) 1
- Achieve target within 3 months, not acutely 1
- Avoid rapid BP reduction as this can precipitate cerebral, renal, or coronary ischemia in patients with chronic hypertension who have altered autoregulation 1, 2
Critical Pitfalls to Avoid
- Do NOT admit to hospital or use IV medications for hypertensive urgency without target organ damage—this represents overtreatment 1
- Do NOT use immediate-release nifedipine due to unpredictable precipitous drops and reflex tachycardia 1
- Do NOT reduce BP to normal within hours—up to one-third of patients with diastolic BP >95 mmHg normalize spontaneously, and rapid lowering may cause harm 1
- Do NOT treat the BP number alone in patients with acute pain or distress, as BP often normalizes when the underlying condition is treated 1
Follow-Up and Monitoring
- Arrange outpatient follow-up within 2-4 weeks to assess response to therapy 1
- Monitor for medication adherence, as non-compliance is the most common trigger for hypertensive crises 1
- Screen for secondary hypertension causes after stabilization, as 20-40% of patients with severe hypertension have secondary causes including renal artery stenosis, pheochromocytoma, or primary aldosteronism 1
- Ensure frequent follow-up (at least monthly) until target BP is reached 1
Special Considerations for Hospitalized Patients
- Current guidelines provide no specific recommendations for managing asymptomatic moderately elevated BP in hospitalized patients 1
- Observational studies suggest intensive inpatient BP treatment may be associated with worse outcomes including acute kidney injury and stroke 1
- Do not apply outpatient BP goals to acute inpatient management, as evidence for aggressive inpatient BP lowering is limited and may cause harm 1
