Randomized trial evaluates cardiac biomarkers in patients with pacemakers and ICDs undergoing MRI, suggesting safe imaging practices.

The study aims to assess cardiac biomarkers before and after MRI scans in patients with permanent pacemakers or ICDs.
Examined 37 patients with 75 leads undergoing 40 MRI scans across various body regions.
Cardiac troponin-I and myoglobin levels were measured immediately before and 6-12 hours after the scans.
Pacemaker capture thresholds were recorded pre- and postscan with standard safety protocols.
Troponin-I levels remained unchanged following MRI (P=0.90).
No significant difference in capture thresholds before and after MRI (P=0.50).
Median peak SAR across all scans was 2.4 W/kg, indicating safe imaging parameters.

Mollerus et al. (2008) studied this question.
