缺血-再灌注损伤可能危及心脏移植术后的短期和长期预后。研究表明,予以供体辛伐他汀具有血管保护作用,可抑制心脏缺血再灌注损伤。84名多器官供者在宣布脑死亡并确定捐献心脏后,随机分为通过鼻胃管接受80 mg辛伐他汀(42位),或不接受辛伐他汀(42位)。主要评估指标是心脏移植后24小时内的肌酐蛋白T和I浓度。次要指标包括术后的血液动力学、炎症、同种异体移植功能、排斥反应和排斥治疗以及死亡率。予以器官供

缺血-再灌注损伤可能危及心脏移植术后的短期和长期预后。研究表明,予以供体辛伐他汀具有血管保护作用,可抑制心脏缺血再灌注损伤。

84名多器官供者在宣布脑死亡并确定捐献心脏后,随机分为通过鼻管接受80 mg辛伐他汀(42位),或不接受辛伐他汀(42位)。主要评估指标是心脏移植后24小时内的肌酐蛋白T和I浓度。次要指标包括术后的血液动力学、炎症、同种异体移植功能、排斥反应和排斥治疗以及死亡率。

予以器官供体辛伐他汀治疗可显著降低心脏移植受体再灌注后6h的肌钙蛋白T(34%,14900±12100ng/L降至9800±7900ng/L)和肌钙蛋白I(40%,171000±151000ng/L降至103000±109000ng/L)的血浆水平;1周时,NT-proBNP的水平降低36%;30天内,排斥治疗的次数减少54%。予以供体辛伐他汀治疗并不影响其血脂水平,但与一个特定的移植心肌活检基因表达谱,和受体术后CXCL10、白介素-1α、胎盘生长因子、血小板源生长因子-BB的血浆水平降低有关。两组的术后血流动力学、活检证实的急性排斥反应和死亡率相近。接受辛伐他汀治疗的供体非心脏实体器官移植的受者也未见不良反应。

予以供体辛伐他汀治疗可降低受体心脏移植后心肌损伤生物标志物的血浆水平,而且安全性可接受,或可作为一种新的、安全的、廉价的多器官捐赠辅助治疗。
