New methods can measure heart iron, impacting chelation therapy. Abnormal T2* MRI findings in patients with and without heart disease may alter treatment strategies for iron overload.

Area of Science:

  • Cardiology
  • Medical Imaging
  • Pharmacology

Background:

  • Iron accumulation in the heart is a growing concern.
  • Current validation of cardiac iron measurement methods lacks direct chemical biopsy evidence.
  • Symptomatic heart disease patients frequently exhibit abnormal T2* MRI values.

Purpose of the Study:

  • To discuss the implications of new methods for measuring cardiac iron.
  • To explore the impact of these findings on chelation therapy protocols.
  • To review treatment options for patients with myocardial iron overload.

Main Methods:

  • Magnetic Resonance Imaging (MRI) for T2* value assessment.
  • Review of current chelation therapies including desferrioxamine (DFO) and deferiprone.

  • Analysis of treatment strategies based on cardiac iron levels.

    • Main Results:

    • Abnormal T2* values are common in symptomatic heart disease.
    • Increased myocardial iron is also observed in patients without symptomatic heart disease.
    • The prognostic significance of increased myocardial iron requires further investigation.

    Conclusions:

    • New cardiac iron measurement techniques are available but require validation.
    • Findings of increased myocardial iron, even without symptoms, are likely to influence chelation therapy.
    • Treatment intensification, switching chelators, or combined chelation are options; intravenous DFO remains recommended for symptomatic patients.
