ST-Segment Elevation Myocardial Infarction Due to Carbon Monoxide Poisoning

Introduction: Carbon monoxide (CO) intoxications, which are often characterized by neurological and respiratory symptoms, are commonly encountered serious poisonings. However, in the literature, although cardiac complications due to poisoning are rarely mortal, conditions such as serious arrhythmias and myocardial infarction have also been reported. Cardiac evaluation and follow-up on CO poisoning is very important for reducing mortality. Case Report: In the present case, we report a ST-segment elevation myocardial infarction (STEMI) believed to be triggered by CO poisoning established in a 48-year-old male patient, whose medical history was unremarkable, admitted to the emergency department due to stove poisoning and chest pain complaint. Conclusion: Although myocardial ischemia is an expected clinical condition in CO intoxications, STEMI is rare. In general, though underlying coronary heart disease is detected on angiography of patients with STEMI due to CO poisoning, in this rare condition, coronary artery anatomy can be completely normal.
