Left ventricular assist device (LVAD) support may facilitate myocardial recovery. We evaluated the impact of LVAD support on Fas expression in a cohort with end-stage heart failure. Myocardial gene expression was assessed pre- and post-LVAD by RNase protection assay and compared to control donor hearts. The expression of Fas is markedly elevated at the time of LVAD support and is tightly correlated with TNF expression. While interleukin (IL)-6 was significantly reduced by LVAD support, the impact of support on Fas was highly variable and tightly linked to tumor necrosis factor (TNF). The role of Fas in predicting recovery after LVAD support requires further investigation.
左心室辅助装置(LVAD)支持可能有助于心肌恢复。我们评估了 LVAD 支持对终末期心力衰竭患者 Fas 表达的影响。通过核糖核酸保护测定法在 LVAD 支持前后评估心肌基因表达,并与对照供体心脏进行比较。在 LVAD 支持时,Fas 的表达明显升高,并与 TNF 表达密切相关。虽然白细胞介素(IL)-6 的表达在 LVAD 支持下显著降低,但支持对 Fas 的影响差异很大,与肿瘤坏死因子(TNF)密切相关。Fas 在预测 LVAD 支持后的恢复中的作用需要进一步研究。
