Evaluation of the Safety and Efficacy of Using Insulin-like Growth Factor-1 in Patients With a Heart Attack (RESUS-AMI)

March 28, 2017 updated by: Professor Noel Caplice, University College Cork

A Randomised Trial Evaluating the Safety and Efficacy of a Single Low Dose of Intracoronary Insulin-like Growth Factor-1 Following Percutaneous Coronary Intervention for ST-Elevation Acute Myocardial Infarction (RESUS-AMI)

When a patient has a heart attack, a blockage occurs in a coronary artery that delivers oxygen to the heart muscle. The heart muscle may weaken, causing heart failure. The body naturally makes a protein called insulin-like growth factor-1 (IGF-1) that may protect the heart muscle cells from dying and may prevent heart failure or lessen the damage that occurs. IGF-1 is also available as a drug called mecasermin. In this study, heart attack patients will be given either a dose of mecasermin or a placebo (inactive treatment) after their coronary artery has been opened by a stent. The purpose of the study will be to evaluate the safety of the therapy and to test if the therapy will prevent or lessen heart failure by evaluating a cardiac magnetic resonance imaging (MRI) taken one day and eight weeks after the heart attack.
