Abstract

Early reperfusion after ST-segment-elevation myocardial infarction is essential for limiting infarct size. However, reperfusion injury can lead to progressive microvascular obstruction (MVO), reducing myocardial blood flow (MBF), aggravating ischemia and myocardial necrosis. We hypothesized that SuperSaturated Oxygen (SSO) Therapy may reduce infarct size by alleviating MVO, so we evaluated the effects of SSO on the time course of MBF and MVO in a preclinical ischemia/reperfusion model.
