Whether pre left ventricular assist device (LVAD) sarcopenia is associated with higher incidence of gastrointestinal bleeding (GIB) on LVAD support remains unknown.To study the association between preoperative sarcopenia and post LVAD GIB events, we performed a retrospective, multi-centered study including patients with chest CTs performed ≤ 3 months prior to LVAD implantation at the University of Minnesota (n = 143) and Houston Methodist Hospital (n = 133). To quantify sarcopenia, unilateral pectoralis muscle mass indexed to body surface area (PMI) and attenuation (approximated by mean Hounsfield units; PHUThe study cohort included 276 LVAD recipients with 43 % designated as bridge to transplant at the time of LVAD implantation. High pectoralis muscle mass and tissue attenuation were both protective against GIB events. Each 5 unit increase in PHUPreoperative sarcopenia, as quantified by pectoralis muscle size and attenuation, was associated with the development of recurrent GI bleeding after LVAD implantation. These CT quantitative measures appear to predict not only early mortality but morbidity on LVAD as well. |
