Background: Carbon monoxide (CO) is a colorless and odorless gas from combustion sources causing accidental or intentional poisoning. Patients present with nonspecific symptoms such as headache and dizziness, but severe cases can lead to altered mental status. Myocardial injury is a life-threatening outcome of CO poisoning, requiring timely evaluation and management.
Case Presentation: A 33-year-old pregnant female with no prior co-morbidities presented to the emergency department with dizziness, vomiting, and syncope. She had been exposed to CO from a petrol generator, resulting in a carboxyhemoglobin level of 9.6%. The patient exhibited global hypokinesia and reduced ejection fraction. After receiving oxygen therapy, she showed improvement and was discharged in stable condition.
Conclusion: This case underscores the importance of early recognition and management of myocardial injury in CO poisoning, particularly in pregnant patients. Prompt oxygen therapy and appropriate follow-up are crucial to mitigate long-term cardiovascular and fetal complications.
Key words: Case report, carbon monoxide poisoning, pregnancy, myocardial injury, cardiomyopathy.
