What Researchers Did
Researchers conducted a prospective cohort study of 230 adult patients treated for moderate to severe carbon monoxide poisoning with hyperbaric oxygen to determine the association between myocardial injury and long-term mortality.
What They Found
Myocardial injury occurred in 85 (37%) of 230 patients. At a median follow-up of 7.6 years, 54 deaths (24%) were observed. Patients with myocardial injury had a significantly higher long-term mortality rate (38%) compared to those without injury (15%), with an adjusted hazard ratio of 2.1 (P = .009).
What This Means for Canadian Patients
Canadian patients who experience moderate to severe carbon monoxide poisoning should be carefully evaluated for myocardial injury. Recognizing this risk can help guide long-term follow-up and management strategies to potentially improve outcomes.
Canadian Relevance
This study was conducted in the United States and has no direct Canadian connection.
Study Limitations
The study was conducted at a single regional center, which may limit the generalizability of its findings to other populations.
