Summary |
Introduction: Cardiac ischemic reperfusion injury (IRI) is paradoxically instigated by re-establishing blood-flow to ischemic myocardium typically from a myocardial infarction (MI). Although revascularization following MI remains the standard of care, effective strategies remain limited to prevent or attenuate IRI. We hypothesized that epicardial placement of human placental amnion/chorion (HPAC) grafts will protect against IRI. Methods: Using a clinically relevant model of IRI, swine were subjected to 45 minutes percutaneous ischemia followed with (MI+HPAC, n=3) or without (MI only, n=3) HPAC. Cardiac function was assessed by echocardiography, and regional punch biopsies were collected 14 days post-operatively. A deep phenotyping approach was implemented by using histological interrogation and incorporating global proteomics and transcriptomics in non-ischemic, ischemic, and border zone biopsies. Results: Our results established HPAC limited the extent of cardiac injury by 50% (11.02.0% vs 22.03.0%, p=0.039) and preserved ejection fraction in HPAC-treated swine (46.8±2.7% vs 35.8±4.5%, p=0.014). We present comprehensive transcriptome and proteome profiles of infarct (IZ), border (BZ), and remote (RZ) zone punch biopsies from swine myocardium during the proliferative cardiac repair phase 14 days post-MI. Both HPAC-treated and untreated tissues showed regional dynamic responses, whereas only HPAC-treated IZ revealed active immune and extracellular matrix remodeling. Decreased endoplasmic reticulum (ER)-dependent protein secretion and increased anti-apoptotic and anti-inflammatory responses were measured in HPAC-treated biopsies. Discussion: We provide quantitative evidence HPAC reduced cardiac injury from MI in a preclinical swine model, establishing a potential new therapeutic strategy for IRI.
