Acute myocardial infarction and coronary artery atherosclerosis
AI-generated summary
A 68-year-old woman presented to St Vincent's Hospital emergency department with upper abdominal and left-sided chest pain following a stationary bicycle fall. Clinicians attributed her symptoms to codeine adverse reaction and rib trauma rather than considering acute coronary syndrome. She deteriorated and suffered a cardiac arrest due to acute myocardial infarction with ventricular rupture. The autopsy revealed severe left anterior descending coronary artery atherosclerosis. Clinicians failed to consider myocardial infarction despite atypical presentation and did not test troponin initially. Key lessons: maintain high suspicion for acute coronary syndrome in females presenting atypically; ensure comprehensive reassessment rather than anchoring to initial diagnoses; consider cardiac causes in chest pain even with alternative explanations.

Failure to consider acute coronary syndrome as differential diagnosis
Anchoring bias to initial assessment of codeine adverse reaction
Atypical presentation of acute coronary syndrome in female patient
Recent trauma confounding clinical assessment
Failure to perform troponin testing initially
Limited Rapid Assessment Team (RAT) assessment potentially introducing bias
History of opioid adverse reaction leading to dismissal of cardiac cause
Coroner's recommendations
St Vincent's Hospital and the Australasian College for Emergency Medicine should consider adopting Sheila Marion Quairney's case as a case study to highlight the importance of comprehensive primary and secondary assessment and the consideration of acute coronary syndrome in females presenting atypically.
