Cardiac troponin I elevation in paediatric cardiac catheterization

Area of Science:

• Pediatric Cardiology
• Cardiovascular Research
• Biomarker Analysis

Background:

• Intracardiac catheterization is a common diagnostic procedure in pediatric cardiology.
• The potential for myocardial damage following these procedures requires thorough investigation.

Purpose of the Study:

• To prospectively evaluate if intracardiac catheterization causes myocardial damage in pediatric patients.
• To assess changes in specific cardiac biomarkers after the procedure.

Main Methods:

• Prospective study involving pediatric patients undergoing diagnostic cardiac catheterization.
• Collection of serum samples pre-procedure and 4-6 hours post-procedure.
• Quantitative analysis of cardiac troponin-I and creatine kinase isoenzyme MB levels.

Main Results:

• The study included 30 pediatric patients (17 males, 13 females) with a median age of 12 months.
• Significant elevations in cardiac troponin I (p<0.05) and creatine kinase isoenzyme MB (p<0.05) were observed post-catheterization.
• Mean cardiac troponin I increased from 0.21+/-0.04 ng/ml to 1.16+/-1.40 ng/ml.
• Mean creatine kinase isoenzyme MB increased from 26.68+/-7.53 U/L to 41.65+/-22.12 U/L.

Conclusions:

• Paediatric diagnostic cardiac catheterization is associated with serum elevations of cardiac troponin I.
• These biomarker elevations suggest potential myocardial injury following the procedure.
• The findings highlight the importance of monitoring cardiac biomarkers in pediatric patients post-catheterization.
