COMBinAtion Therapy in Myocardial Infarction: The COMBAT-MI Trial

Summary

Remote ischemic conditioning (RIC) and intravenous exenatide administered immediately before primary angioplasty have been found to limit infarct size in patients with STEMI (ST segment elevation myocardial infarction), but the reduction is limited. This study investigates whether a combination therapy including both therapies is more effective.
