Coroner's Finding: McKenzie, Heather Patricia Dale

67y · Female·mixed alcohol and drug toxicity

Heather Patricia Dale McKenzie, a 67-year-old woman with a documented history of heavy alcohol consumption and hypertension, died aboard a cruise ship from mixed alcohol and drug toxicity. She had consumed considerable alcohol before retiring and was found unconscious by her husband at 1:45am. Despite CPR by ship's medical staff and paramedics, resuscitation was unsuccessful. Autopsy revealed a blood alcohol concentration of 0.337 g/100mL (above the potentially fatal threshold of 0.4) and amlodipine at supratherapeutic levels (0.05 mg/L versus therapeutic 0.001-0.02 mg/L). A significant drug-alcohol interaction was identified as the likely mechanism. The coroner found no suspicious circumstances. Clinically, this case highlights the dangers of alcohol-medication interactions, particularly with calcium channel blockers, and the importance of patient education regarding alcohol consumption in those on antihypertensive therapy.
