Detailed Description:

Percutaneous coronary intervention (PCI) has become the mainstay for treatment of ST-segment elevation myocardial infarction (STEMI). Whereas early recanalization undoubtedly salvages myocardial tissue, reperfusion following prolonged ischemia can also exacerbate injury. Infarct size needs to be limited, and the conditions favoring adaptive ventricular healing and remodeling optimized because in patients with acute myocardial infarction (AMI) who do not die of out-of-hospital arrhythmias, long-term prognosis is dependent on the amount of myocardium that is lost, and the outcome of ventricular remodeling. Angion Biomedical Corp. has identified BB3, a small molecule mimetic of hepatocyte growth factor/scatter factor (HGF/SF) whose activity is expected to preserve tissue viability and attenuate dysfunction in the setting of organ injury while obviating the logistical difficulties associated with gene or protein therapy. HGF/SF is a naturally occurring cell survival factor that holds significant therapeutic potential. BB3 has been shown to possess HGF/SF activities, including protection against heart injury following myocardial infarction. This study is designed to evaluate clinical efficacy of BB3 in patients presenting with acute ST segment elevation myocardial infarction (A-STEMI) who undergo PCI.
