Cause of death
Sibutramine ingestion in a woman with coronary artery atherosclerosis
AI-generated summary
Karen Willis, a 45-year-old woman with no known medical conditions, died of acute cardiac arrhythmia triggered by sibutramine ingestion combined with underlying coronary atherosclerosis. She had purchased Slimming Factor weight-loss tablets online, marketed as herbal but containing undisclosed pharmaceutical agents including sibutramine (withdrawn from Australian markets in 2010 due to cardiovascular safety concerns), fenfluramine, and other cardiotoxic substances. She presented with chest pain and indigestion before sudden collapse. A TGA safety alert had been issued prior to her death. Clinicians should counsel patients against purchasing unregistered medications online and emphasize that herbal-labeled products may contain dangerous hidden pharmaceuticals. Early recognition of chest pain with risk factors warrants urgent cardiac evaluation and consideration of substance-induced arrhythmia.
