Metformin to Reduce Heart Failure After Myocardial Infarction
Overview[ - collapse ][ - ]
Purpose | The investigators will evaluate the effect of metformin therapy during 4 months in non-diabetic patients following ST-elevation myocardial infarction on left ventricular ejection fraction as measured with cardiac magnetic resonance imaging, compared to placebo. |

Current Primary Outcome Measures | Improvement in left ventricular ejection fraction [Time Frame: 4 months] [Designated as safety issue: No]The primary efficacy parameter of the GIPS-III trial is LVEF measured by cardiac MRI 4 months after randomization, based on an intention-to-treat analysis. It is hypothesized that metformin therapy will result in a higher ejection fraction after 4 months. |

Brief Summary | The investigators will evaluate the effect of metformin therapy during 4 months in non-diabetic patients following ST-elevation myocardial infarction on left ventricular ejection fraction as measured with cardiac magnetic resonance imaging, compared to placebo. |
Detailed Description | In this trial, the investigators will evaluate the effect of metformin therapy following ST-elevation myocardial infarction (STEMI) in a total of 380 non-diabetic patients. This trial is a randomized, double blind, controlled trial. The intervention, which consist of metformin 500mg twice daily or placebo twice daily, will commence within three hours after the percutaneous coronary intervention, and will be continued for 4 months. The primary endpoint is the difference between the two intervention groups (metformin vs placebo) in left ventricular ejection fraction, as measured with magnetic resonance imaging after 4 months. The investigators hypothesize that metformin therapy results in a significantly higher ejection fraction in this population. |
