Study Notes
Hypertensive Crisis
- SBP >180 mmHg and/or DBP >120 mmHg
Hypertensive Emergency
- Requires hospitalization due to target organ damage
- Can result in severe problems if not promptly recognized and treated
- Associated with:
- Encephalopathy
- Intracranial or subarachnoid hemorrhage
- Heart failure (HF)
- Myocardial infarction (MI)
- Renal failure
- Dissecting aortic aneurysm
- Retinopathy
- Untreated, mortality rate is 79% in one year
Hypertensive Urgency
- More common than hypertensive emergency
- No evidence of target organ disease
- Hospitalization usually not required
- Associated with chronic stable disorders:
- Stable angina
- Chronic HF
- Prior MI or CVA
Causes of Hypertensive Crisis
- History of HTN; non-adherence or undermedication
- Use of substances:
- Cocaine
- Amphetamines
- PCP
- LSD
- Leading to seizures, stroke, MI, or encephalopathy
Clinical Manifestations
- Hypertensive encephalopathy:
- Altered mental status
- Headache
- Nausea/vomiting
- Seizures
- Confusion
- Coma
- Retinal changes
- Renal insufficiency
- Cardiac decompensation:
- MI
- HF
- Pulmonary edema
- Chest pain
- Dyspnea
- Aortic dissection:
- Chest and back pain
- Reduced/absent peripheral pulses
Nursing and Interprofessional Care
- Hospitalization for HTN emergency
- Treatment focused on BP and evidence of target organ disease
- IV drugs:
- Slow titration
- MAP 110 to 115 mmHg
- MAP = (SBP +2 DBP) ÷ 3
- Drugs:
- Vasodilators (e.g., sodium nitroprusside)
- Adrenergic inhibitors
- Calcium channel blockers
- Monitoring:
- HR and BP q. 2 to 3 minutes
- Cardiac and renal function
- Neurological checks
- Bed rest for those on IV drugs
- Determine cause of crisis
- Education to avoid future crisis
Hypertensive Urgency: Outpatient Care
- Common oral meds:
- Captopril
- Labetalol
- Clonidine
- Amlodipine
- Require follow-up, often within 24 hours
