Can indicators of myocardial damage predict carbon monoxide poisoning outcomes?

Carbon monoxide causes electrical, functional, and morphological changes in the heart. It is unclear, however, whether the indicators of myocardial damage can predict the patient's prognosis after carbon monoxide poisoning. This retrospective study aimed to investigate the relationship between...

Description
Summary:Carbon monoxide causes electrical, functional, and morphological changes in the heart. It is unclear, however, whether the indicators of myocardial damage can predict the patient's prognosis after carbon monoxide poisoning. This retrospective study aimed to investigate the relationship between the carboxyhemoglobin level and electrocardiographic (ECG) changes and whether the ECG changes and troponin I levels are related to the patient's prognosis after carbon monoxide poisoning. Carboxyhemoglobin, troponin I, and ECG parameters were measured in 70 patients with carbon monoxide poisoning. The QT and RR intervals were measured for each ECG lead in all patients, and the corrected QT interval and corrected QT dispersion were calculated. The correlation between the maximum corrected QT interval and the carboxyhemoglobin level was significant (P = 0.0072, R  = 0.1017), as were the relationships between QT dispersion and carboxyhemoglobin (P
