Troponin I Levels After Cardioversion in 73 Atrial Arrhythmia Patients

73 individuals undergoing synchronized DC cardioversion for atrial arrhythmias had blood work performed before and six hours after the procedure. The study, led by Ryan T. Sless from University College Cork, found no significant overall change in cardiac troponin I levels post-cardioversion, suggesting the procedure did not cause myocardial injury at that time point. A subgroup analysis indicated a significant reduction in troponin I for patients without cardiomyopathy.

Use Cases

• Analyze the relationship between cardioversion and myocardial injury based on pre- and post-procedure troponin I measurements.
• Investigate the effect of cardiomyopathy on biomarker response based on the subgroup analysis mentioned.
• Model the correlation between change in troponin I and cumulative energy or left ventricular mass as described in the secondary outcomes.
• Study inflammatory response by examining C-reactive protein (CRP) levels collected alongside troponin I.

Strengths

• Includes data from 73 patients (59 men, 14 women), providing a specific cohort size.
• Contains paired pre- and post-procedure measurements for troponin I and CRP, enabling within-subject analysis.
• Secondary outcomes include analysis stratified by cardiomyopathy presence, adding a layer of clinical detail.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal or source bias inherent to paperswithcode.
