背景资料：我们以前已经证明，术前CT扫描获得的胸肌质量和组织衰减是左心室辅助装置植入后死亡率的有力预测因素。在这项分析中，我们在一个单独的左心室辅助装置植入队列中证实了我们的发现，我们提出了一个新的、用户友好的死亡率预测模型，该模型结合了这些指标。
Background: We have previously demonstrated that pectoralis muscle mass and tissue attenuation obtained on preoperative CT scans were powerful predictors of mortality after left ventricular assist device implantation. In this analysis, we confirm our findings in a separate left ventricular assist device implantation cohort, and we present a novel, user-friendly mortality-prediction model incorporating these measures.Methods and Results: Patients with chest CTs performed
