Spence, John Michael

51y · Male·Combined effects of atherosclerotic cardiovascular disease and seizure activity in the setting of excessive caffeine use

John Spence, a 51-year-old man with a history of seizures, alcoholism, and severe coronary artery disease, died in a prison health centre following a seizure episode. He had ingested an extraordinarily high level of caffeine (64mg/L, equivalent to approximately 2000mg or 20 espresso coffees), which precipitated a fatal cardiac event in the context of critical coronary artery stenosis (90% occlusion of left anterior descending artery). Clinical lessons: undiagnosed caffeine toxicity contributed to death; seizure disorder was never formally diagnosed despite multiple presentations (no neurology referral or EEG); anti-convulsant levels were subtherapeutic; and inadequate documented care plans and observation protocols followed the Code Blue incident. The prison subsequently implemented improved documentation systems, vital signs monitoring, and ECG screening for patients over 50 on reception.
