• After Exercise Mechanical Dyssynchrony and Acute Response to Cardiac Resynchronization Therapy in Patients with Congestive Heart Failure Rochester, Minn.

  The purpose of this study is to assess the presence and severity of mechanical dyssynchrony in patients with congestive heart failure (CHF) when selecting to CRT in resting and after-exercise echocardiography by multiple echocardiographic techniques, and to evaluate association of exercise-induced mechanical dyssynchrony with acute response to CRT. 

• Community Paramedic Hospitalization Reduction and Mitigation Program: Pragmatic Clinical Trial Rochester, Minn., Eau Claire, Wis.

  The purpose of this study is to evaluate the effectiveness of the Care Anywhere with Community Paramedics (CACP) program in reducing hospitalizations among patients being cared for in the emergency department or hospital.

   

   

• Correlation of Bioimpedance Measurements From the SOZO Device With Pulmonary Arterial Pressure Measurements From the CardioMEMS HF System Rochester, Minn.

  This study aims to establish the degree to which change in the ratio of ECF to TBW measured using the SOZO BIS device correlates with change in end-expiratory end-diastolic PAP measured using the CardioMEMS HF System (St. Jude Medical).

• Non-Invasive Monitoring of Potassium Levels in Patients with Congestive Heart Failure Rochester, Minn.

  The purpose of this study is to examine that signal processed ECGs can be used to monitor changes in serum concentrations of potassium based on T-wave features.

• Usefulness of Color M-mode for Vena Contracta of Aortic Regurgitation in Patients with Left Ventricular Assist Devices Rochester, Minn.

  The purpose of this study is to assess the feasibility of color M mode and standard vena contracta measurements and compare these to novel measurements of aortic regurgitation in left ventricular assist devices (LVADs).
