Summary

Treatment with prednisone and azathioprine improved heart inflammation in myocarditis patients. Some patients experienced worsening symptoms after treatment withdrawal, indicating a need for careful management of immunosuppression.

Area of Science:

  • Cardiology
  • Immunology
  • Pathology

Background:

  • Myocarditis is an inflammatory condition of the heart muscle.
  • Biopsy-proven myocarditis requires effective treatment strategies.
  • Current treatment options aim to reduce inflammation and preserve cardiac function.

Purpose of the Study:

  • To evaluate histologic changes during and after prednisone and azathioprine treatment in myocarditis.
  • To assess changes in left ventricular ejection fraction (LVEF) in response to treatment.
  • To establish the relationship between histologic status, immunosuppression, and LVEF.

Main Methods:

  • Twenty patients with biopsy-proven myocarditis were treated with prednisone and azathioprine.
  • Multiple endomyocardial biopsies were performed to monitor histologic changes.

  • Treatment was adjusted to achieve complete resolution of myocardial inflammation.

    • Main Results:

    • Histologic status improved in all patients; complete resolution of active disease occurred in 15 patients.
    • A significant overall improvement in left ventricular ejection fraction was observed (0.37 to 0.46).
    • Fifty percent of patients showed worsening after treatment withdrawal, suggesting a link between immunosuppression and disease activity.

    Conclusions:

    • Prednisone and azathioprine treatment may benefit patients with biopsy-proven myocarditis and reduced ventricular function.
    • Careful management of immunosuppression is crucial, as withdrawal can lead to disease relapse.
    • Further research is needed to confirm the direct impact of treatment on LVEF recovery.
