Clinical Trial Summary

Prediabetes is associated to an increased risk of cardiovascular disease and mortality. Although metformin can delay progression to diabetes there is a lack of RCTs evaluating the effect of metformin on cardiovascular outcomes. MIMET aims to investigate if addition of metformin to standard care has effects on the occurrence of cardiovascular events after acute myocardial infarction in patients with newly detected prediabetes (identified by oral glucose tolerance test, HbA1c or fasting glucose levels).


Clinical Trial Description

The study is a national multicenter R-RCT associated to the The Swedish Web-system for Enhancement and Development of Evidence-based care in Heart disease Evaluated According to Recommended Therapies (SWEDEHEART registry) where participants, after informed consent, will be randomly assigned to either open treatment with standard care + metformin or standard care alone in a 1:1 ratio. Standard care consists of diet and life-style advice according to national guidelines but does not include metformin. Baseline data for individual patients will be collected from the SWEDEHEART registry. Patients will be followed per routine care at 2 and 12 months post index AMI and in addition at a final study visit at 24 months. Laboratory measurements and collection of SAE will be performed yearly. In total n=5150 patients is expected to be followed for major CV event (all-cause mortality, myocardial infarction, heart failure and stroke) by linkage with SWEDEHEART and national health registries. ;
