Overview
The goal of this clinical trial is to assess the safety and efficacy of SGLT2i in limiting infarct size in patients with STEMI referred for PPCI.
Eligible STEMI patients enrolled into the trial will be randomized to a SGLT2i or placebo.
Cardiovascular Magnetic Resonance (CMR) imaging will be used to determine the infarct size.
Description
DAPA STEMI is a single center, randomized, double-blind, parallel group study in which eligible participants with a STEMI and undergoing PPCI will be recruited and randomly assigned to dapagliflozin or placebo to take for 7 days. Participants will be prescribed study treatment i.e. dapagliflozin (10 mg) or placebo daily for 7 days.
A CMR will be obtained at day 3-5 to assess for infarct size. Participants will have follow-up visits at 30, 90, and 180 days to assess for cardiovascular events.
Eligibility
Inclusion Criteria:
Patients referred for PPCI meeting the following criteria are eligible for the study:

Extensive non-anterior STEMI defined as ST-segment elevation of >1mm in two or more contiguous non-anterior leads accompanied by i. 8 or more leads with > 1 mm ST elevation or depression, or both; OR ii. Sum of ST- segment elevation >20mm
