Description
Inclusion Criteria -
- Adult (18 - 79 years).
- First STEMI (EMS/ER ECG ST-elevation) with primary PCI planned.
- Consent pathway available: Patient consent, Legally Acceptable Representative (LAR)
- CMR likely be feasible (no known MRI-unsafe implant or absolute MRI prohibition)
Exclusion Criteria -
- History of PCI or CABG within 1 year
- Known dialysis/ESRD
- Known pre-existing LVEF <40% from recent records
- Known pregnancy or breastfeeding (history or clearly documented)
- Current anthracycline chemotherapy or active chest radiation (per patient/chart).
- On iron chelation now or documented iron-storage disease (hemochromatosis/thalassemia).
- Concurrent trials: investigational drug or device use within 90 days.
- Any clinically significant condition identified that would preclude safe peri-procedural administration of Dexrazoxane or completion of core protocol procedures.

Participant Group / ArmParticipant Group / Arm |
Intervention / TreatmentIntervention / Treatment |
|---|---|
|
Experimental: Dexrazoxane Infusion
Participants receive an intravenous infusion of Dexrazoxane in the ER, followed by doses at 4, 8, and 12 hours post-primary PCI.
|
Intravenous infusion administered adjunctively to primary PCI
|
|
Placebo Comparator: Placebo Infusion
Participants receive an intravenous infusion of Normal Saline (0.9% NaCl) - visually identical to the investigational product - in the emergency room prior to primary PCI, followed by doses at 4, 8, and 12 hours post-primary PCI, adjunctive to standard of care.
|
Visually identical placebo infusion (Normal Saline 0.9% NaCl) of similar volume administered adjunctively to primary percutaneous coronary intervention (PCI).
Administered at four timepoints: emergency room (pre-PCI), 4 hours, 8 hours, and 12 hours post-primary PCI, identical in appearance, volume, and schedule to the investigational product.
