Cardiac Power Output in Cardiogenic Shock Patients

This study is designed as a prospective, observational, crossover study to assess the feasibility of using differences in invasive hemodynamics of cardiac function, representing myocardial reserve, to predict clinical outcomes for heart failure patients. Patients with heart failure referred for right heart catheterization (RHC) by the advanced heart failure team as part of 1) evaluation for advanced heart failure therapies, including left ventricular assist device (LVAD), orthotopic heart transplant (OHT), temporary or long-term inotrope therapy, or counter-pulsation (temporary intra-aortic balloon pump (IABP) or long-term with NuPulse device), 2) for accurate assessment of invasive hemodynamics due to worsening clinical status, 3) assessment of myocardial recovery for consideration of LVAD or NuPulse decommissioning or removal or mechanical circulatory support removal, or 4) accurate assessment of cardiac function in patients with reduced LVEF prior to valve replacement for aortic insufficiency (AI) or mitral regurgitation (MR).
