What Researchers Did
This report describes a case of intracardiac thrombus formation following carbon monoxide poisoning.
What They Found
Researchers reported a case of a 24-year-old woman with carbon monoxide poisoning (initial CO fraction 16%) who developed a 30x15 mm right atrial thrombus 24 hours after exposure. Her initial cardiac markers were elevated (creatinine kinase-myocardial bound 90.6 ng/mL, troponin I 1.899 ng/mL), and the thrombus resolved after 7 days of low-molecular-weight heparin and hyperbaric oxygen therapy.
What This Means for Canadian Patients
Canadian patients experiencing carbon monoxide poisoning should be aware of potential serious cardiac complications, including intracardiac thrombus formation, which can lead to pulmonary embolism or stroke. Early cardiac assessment and appropriate management, such as anticoagulation, are important for preventing adverse outcomes.
Canadian Relevance
This study has no direct Canadian connection as it is a single case report from outside Canada.
Study Limitations
As a single case report, the findings of this study cannot be generalized to a broader patient population.
