BACKGROUND: Preclinical studies have consistently shown that erythropoietin (EPO), administered after an acute myocardial infarction (AMI), reduces infarct size and improves left ventricular function. Furthermore, EPO promotes endothelial progenitor cell growth, which increases angiogenesis. A recent pilot study in patients with AMI suggested that a single bolus of EPO was safe and well tolerated. METHODS: The HEBE III is a multicenter, prospective, randomized, open-label trial with blinded evaluation of the primary end point. The primary objective is to study the effect on left ventricular ejection fraction (LVEF) of a single bolus of EPO, administered directly after a primary percutaneous coronary intervention (PCI) for a first AMI. A total of 466 patients with thrombolysis in myocardial infarction 0/1 flow before the PCI procedure and 2/3 flow after a successful PCI are randomly assigned to either receive standard medical care or a single bolus with 60,000 IU of EPO on top of standard medical care within 3 hours of the PCI procedure. Primary end point of the study is LVEF after 6 weeks, assessed by planar radionuclide ventriculography. IMPLICATIONS: If an improvement of LVEF with a single bolus of EPO is demonstrated, this simple approach might further improve clinical outcome of patients with AMI.
