About this trial
This study aims to determine, via skeletal muscle ultrasound (US), the extent, timing and relationship between skeletal muscle mass loss and outcomes after orthotropic heart transplantation (OHT) and left ventricular assist device (LVAD) implantation amongst patients with cardiogenic shock. Advanced therapies such as OHT and VADs in the heart failure (HF) population may promote skeletal muscle mass and subsequent quality of life, but there is a lack of literature assessing muscle mass changes in HF patients before and after advanced therapies using US imaging. Therefore this observational study will provide further insight into the 1) changes in lean body mass during critical illness and 2) the feasibility of using bedside US to assess lean body mass in the inpatient setting.
Eligibility criteria
Qualifiers

Ejection fraction <40%
Cardiogenic shock defined by clinical criteria (including any of: lactate >2.5 mmol/L, systolic blood pressure <90 mmHg, acute kidney or liver injury, or cardiac index <2.1 on hemodynamic monitoring) plus the clinical requirement for at least one pressor, inotrope, or temporary mechanical circulatory support device (MCSD)
Disqualifiers
