Summary
This summary is machine-generated.Early assessment of left ventricular function in active myocarditis patients predicts long-term outcomes. Re-evaluating left ventricular ejection fraction (LVEF) at six months significantly improves prognostic accuracy for heart transplantation-free survival.
Area Of Science
- Cardiology
- Immunology
- Pathology
Background
- Active myocarditis presents with diverse clinical features and outcomes.
- Identifying early prognostic markers is crucial for managing this heterogeneous condition.
- This study investigates predictors of long-term prognosis in biopsy-proven active myocarditis.
Purpose Of The Study
- To identify accessible and valid early predictors of long-term prognosis in patients with active myocarditis.
- To evaluate the prognostic value of baseline and short-term (6-month) left ventricular function.
- To assess the association between clinical and echocardiographic parameters and heart transplantation-free survival.
Main Methods
- Retrospective analysis of 82 patients with biopsy-proven active myocarditis.
- Clinical and echocardiographic evaluations at baseline and 6 months.
- Assessment of left ventricular ejection fraction (LVEF) improvement/normality at 6 months.
- Long-term follow-up for heart transplantation-free survival.
Main Results
- Baseline left ventricular dysfunction (LVEF<50%) and left atrium enlargement predicted long-term survival.
- At 6 months, 53% of patients showed improved or normal LVEF.
- Persistence of NYHA III-IV, left atrium enlargement, and 6-month LVEF status were independent predictors of outcome.
- 6-month reevaluation significantly improved prognostic accuracy compared to baseline (AUC 0.90 vs. 0.79).
Conclusions
- Baseline left ventricular function is a key prognostic indicator in active myocarditis, irrespective of clinical presentation.
- Reassessing left ventricular ejection fraction (LVEF) at 6 months provides valuable prognostic information for longer-term outcomes.
- Early echocardiographic assessment aids in risk stratification and management planning for myocarditis patients.
