Pediatric Myocarditis Severity Index (PMSI) Calculator
- Pediatric Myocarditis Severity Index: Explanation and Clinical Context
The Pediatric Myocarditis Severity Index (PMSI) is a clinical tool designed to stratify the risk and predict outcomes in children with acute myocarditis.
It incorporates key variables including age, heart rate, left ventricular ejection fraction (LVEF), serum troponin I levels, and BNP levels to provide an integrated risk score.
A higher PMSI score indicates greater disease severity, higher risk of hemodynamic compromise, and potentially higher mortality.
Clinicians can use PMSI for early risk stratification, guiding decisions on monitoring intensity, admission to ICU, and initiation of advanced therapies such as inotropes or mechanical circulatory support.
