Enlarged Heart

The purpose of the research is to determine whether a class of medication called SGLT2 inhibitor will improve the heart's function and reduce its enlargement after a heart attack. Participation in this study will involve taking this class of medication (or a placebo) once daily for six months, one cardiac magnetic resonance imaging (MRI) test during your initial hospitalization, follow-up phone calls at 1 and 3 months, and one cardiac MRI and clinic visit at six months. This is a single center study.
