Abstract:
Antiplatelet agents are routinely given to prevent thrombosis of coronary stents. Often this occurs during or immediately after the procedure, while the patient is still on the catheterisation laboratory table. Ingestion of pills while supine sometimes causes mild dysphagia and discomfort but, rarely, it can cause a more severe complication. We report a case of clopidogrel ingested during PCI, which caused chest pain and pill oesophagitis after the procedure. Conservative treatment was effective, symptoms resolved, and follow-up endoscopy showed resolution of the oesophageal inflammation.
