Study summary

Angiotensin-converting enzyme inhibitor ACEi induced angioedema ACEi-AE is defined as physical swelling of the deep skin layers or mucous membranes due to increased vascular permeability and leakage of fluid into the interstitial space caused while taking an ACEi

Read the detailed description

Angiotensin-converting enzyme inhibitor ACEi induced angioedema ACEi-AE most commonly affects the lips, mouth, face, upper airway, and less commonly the gastrointestinal tract. This condition may lead to life-threatening airway compromise which would require emergent intubation. Currently, strong evidence is lacking to help guide management of ACEi-AE in the emergency department (ED).
