Key result
Severe carbon monoxide poisoning triggers acute STEMI in undiagnosed coronary artery disease.
Why the study?
Myocardial injury is a known complication following acute carbon monoxide poisoning, but there is little literature on this subject.
Case Report (n=1)
No
This case highlights that carbon monoxide intoxication can trigger acute myocardial infarction in the setting of underlying coronary artery disease, underscoring the importance of cardiac evaluation (ECG and enzymes) in these patients.
May warrant cardiac evaluation in severe CO poisoning with CAD risk factors; single case leaves open need for prospective validation.
Myocardial injury is a known complication following acute carbon monoxide (CO) poisoning, yet there is little literature on this subject. Here, we present the case of a 56-year-old man admitted to the emergency room with severe CO poisoning. The electrocardiogram (ECG) at admission revealed an ST-segment elevation in leads II, III, and aVF, with an elevated troponin-T level. The patient was initially treated with hyperbaric oxygen, with improvement of symptoms and ECG normalization. He was later admitted for coronary angiography, which revealed an occlusion of the right coronary artery. This case aims to highlight an often-overlooked complication of CO intoxication and the need for more studies to better guide the treatment of these patients.

Camacho et al. (2023) conducted a case report in Carbon monoxide poisoning and acute myocardial infarction (n=1). Carbon monoxide poisoning was evaluated. Severe carbon monoxide poisoning acted as a trigger for an acute ST-elevation myocardial infarction in a 56-year-old man with underlying, previously undiagnosed coronary artery disease.
