Heartbreaking Case of Acetaminophen Poisoning

Abstract

A 23-year-old woman was brought to the emergency room after ingesting 50 g of acetaminophen. Her blood acetaminophen level was 158 mg/L, and she later developed fulminant hepatic failure. Sixty-three hours after ingestion, ECG displayed signs suggestive of acute ischemic injury (Figure 1A). Serum enzymes revealed a Troponin-I of 227.2 ng/mL. The patient’s declining clinical status precluded a cardiac catheterization study. She died within 72 hours of admission in spite of orthotopic liver transplantation. Autopsy revealed normal patent coronary arteries, and cardiac tissue histology displayed patchy subendocardial necrosis and hemorrhage in the ventricles and septum (Figure 1B and 1C) probably due to direct acetaminophen toxicity …
