Experimental: Prochymal®
Participants will receive Prochymal® single intravenous (IV) infusion at a dose of 200 x 10^6 human mesenchymal stem cells (hMSC), reconstituted in 80 mL, delivered at a rate of 2 mL/min, with a maximum rate of 5.0 x 10^6 hMSC/minute, and the participants will be followed for 24 months and remain in the study for up to 60 months.

- Change from Baseline in Cardiac Magnetic Resonance (CMR) imaging-determined End Systolic Volume (ESV) at Month 3 [ Time Frame: Baseline, Month 3 ]
- Left Ventricular End Systolic Volume [ Time Frame: 6 months ]
- Infarct Size [ Time Frame: 3 and 6 months ]
- Left Ventricular Ejection Fraction [ Time Frame: 3 and 6 months ]
- Left Ventricular End Diastolic Volume [ Time Frame: 3 and 6 months ]
- Number of Participants with Ventricular Arrhythmias [ Time Frame: 3 and 6 months ]
- Duke Activity Status Index (DASI) Assessment [ Time Frame: 6, 12, and 24 months ]The Duke Activity Status Index (DASI) is a brief, self-administered questionnaire that provides a standardized assessment of functional status and quality-of-life that correlates well with an objective measure of maximal exercise capacity. The scale ranges from 0 (unable to perform any tasks) to 58.20 (able to perform all tasks). Higher scores indicate a greater ability to perform daily activities.
