Fatal angioedema associated with enalapril
Internal Medicine (Tokyo, Japan)
|April 1, 1993
Summary
Enalapril, an ACE inhibitor, can cause rare but life-threatening angioedema, leading to swelling and respiratory arrest. Prompt medical attention is crucial for managing this severe adverse reaction.
Area of Science:
- Pharmacology
- Cardiovascular Medicine
- Allergy and Immunology
Background:
- Hypertension is a common cardiovascular condition managed with medications like enalapril.
- Angioedema is a known, albeit rare, adverse effect of angiotensin-converting enzyme (ACE) inhibitors.
- Early recognition and management of angioedema are critical for patient outcomes.
Observation:
- A 37-year-old female presented with tongue and neck swelling after enalapril initiation.
- Initial treatment with hydrocortisone provided temporary relief of dyspnea and dysarthria.
- Recurrent symptoms led to respiratory arrest, severe anoxic brain damage, and subsequent death.
Findings:
- The patient experienced severe angioedema secondary to enalapril.
- Despite initial treatment, the angioedema progressed to a fatal outcome.
- This case highlights the potentially life-threatening nature of enalapril-induced angioedema.
Implications:
- Clinicians must maintain a high index of suspicion for angioedema with ACE inhibitor use.
- Rapid and aggressive management strategies are necessary for ACE inhibitor-induced angioedema.
- Patient education regarding potential severe adverse reactions to antihypertensive medications is essential.
