AI-generated summary
Wayne Mitchell, a 49-year-old man, presented to a clinic with acute chest pain radiating to his jaw, accompanied by dizziness, diaphoresis, and dyspnoea. His symptoms resolved before ambulance arrival. The paramedics performed a normal ECG and transported him to a primary care clinic rather than hospital. Dr V. assessed Mitchell as low-risk for myocardial infarction without repeating the ECG or establishing a working diagnosis. When troponin results returned at 45 ng/L (elevated), Dr V. misinterpreted the pathology report and took no action, failing to apply the chest pain protocol. Mitchell died that evening from left main stem coronary artery occlusion with thrombosis. Expert evidence indicated that timely recognition of the elevated troponin, repeat ECG, hospital admission, and cardiology involvement would have likely prevented his death. This case highlights the critical importance of applying acute coronary syndrome protocols regardless of symptom resolution, correctly interpreting troponin results, and maintaining a low threshold for hospital referral in patients with risk factors and typical ACS symptoms.

Error types
Clinical conditions
Contributing factors
- failure to apply chest pain protocol despite resolution of symptoms
- failure to perform repeat ECG when troponin was elevated
- misinterpretation of troponin result and pathology reference range
- premature discharge from clinic without appropriate risk stratification
- inadequate clinical documentation and history taking
- failure to establish a working diagnosis
- inappropriate triage to primary care clinic instead of hospital
- failure to recognize multiple cardiac risk factors (smoking history, daily drinker)
- failure to recognize constellation of ACS symptoms (chest pain radiating to jaw, diaphoresis, dyspnoea, nausea, pallor)
Coroner's recommendations
- No specific recommendations made by the coroner, noting that AHPRA's actions and Dr V.'s compliance with undertakings to undergo remedial education and supervision were deemed appropriate remediation.
