Terapia con deferiprone guidata da risonanza magnetica cardiaca per pazienti con infarto miocardico acuto (MIRON-DFP)
The objective of this randomized, controlled pilot study is to determine the efficacy of Deferiprone to reduce the amount of free iron inside the hemorrhagic zone of myocardial infarction among hemorrhagic myocardial infarction patients.

Descrizione dettagliata
Patients with newly diagnosed STEMI (ST-segment elevation myocardial infarction) who appear to meet eligibility criteria will be recruited for participation. Those who agree to participate and are confirmed to be eligible will undergo a cardiac MRI scan and will be randomized to take either deferiprone or placebo daily for 60 days. Total study participation will last 6 months, during which study participants will attend 7 study visits for blood draws, ECGs, and a repeat cardiac MRI at Day 180.

Comparatore attivo: Hemorrhagic Myocardial Infarction - Deferiprone
Enrolled patients with CMR confirmed presence of intramyocardial hemorrhage |
Deferiprone tablets are the active medication for the active arm of the study groups. Randomization will be done by investigational drug services pharmacist and intervention will be double-blinded to investigators and patients. |

Comparatore placebo: Hemorrhagic Myocardial Infarction - Placebo
Enrolled patients with CMR confirmed presence of intramyocardial hemorrhage |
Deferiprone placebo is the non-medicated formulation for a control arm of the study groups. |
