Angioedema Due to Angiotensin-converting Enzyme Inhibition: an Association Frequently Unrecognized

Angioedema as a side effect of treatment with angiotensin-converting enzyme inhibitors is often under-recognized. We analyzed the subjects seen in our out-patient clinic for angioedema. Over the past 3 years, we have found a cause-effect relationship between angiotensin-converting enzyme inhibitor treatment and angioedema in 14 of the 334 subjects presenting with this condition.
