Impact of Interval Training on Sympathetic Hyperactivity and Vascular Function
In this study, the investigators are testing the hypothesis that reduction in sympathetic activity would be greater following high-intensity interval training (HIIT) than moderate-intensity continuous training (MICT) and correspond with improvements in peripheral vascular function, and skeletal muscle function in patients with heart failure with reduced ejection fraction (HFrEF).

Preoperative Percutaneous RVAD to Preemptively Treat Right Heart Failure Post-LVAD
Prior studies have shown that left ventricular assist device (LVAD) implantation commonly results in right ventricular failure (RVF). Right ventricular dysfunction and failure after LVAD implantation is known to increase morbidity and mortality and contribute to longer post-implant hospital length of stay. Since RVF is difficult to predict and can …
