Prevalence and Clinical Course of Methemoglobinemia After Cardiac Device Implantation.

Key Points

• This research aims to investigate the prevalence of methemoglobinemia after cardiac device implantations and its clinical implications.
• Conducted an observational study on patients receiving cardiac implantable electronic devices (CIEDs).
• Monitored methemoglobin levels post-implantation.
• Established practical thresholds for early recognition, specifically >3% FMetHb.
• Found that methemoglobinemia occurs more frequently than previously thought after CIED implantation.
• Early recognition and management of levels above 3% FMetHb led to improved clinical outcomes.
