1、胸部肿瘤患者放疗时心肌肌钙蛋白I变化的研究【摘要】目的:寻找胸部肿瘤放疗心脏受照时,早期发现心肌损伤的血清标志物,以利于尽早预防和治疗放疗并发症和后遗症。方法:30例胸部肿瘤患者为观察组,30例非胸部肿瘤者为对照组;分别采用普通放疗,Gy/d,5次/周,前后对穿照射达40Gy后,所有患者分别在放疗前、放疗剂量达40Gy、放疗结束时和放疗后1个月检测cTnI。结果:血清cTnI浓度>/ml为诊断心肌损伤的界限值。放疗前与DT0Gy时cTnI含量轻度升高,P<,差异有显著性;放疗前与放疗结束时比较显著升高,P<,有极非常显著的统计学意义;放疗前与放疗后1个月的比较,P<;放疗DT0Gy与放疗结
2、束时比较,P<,有非常显著的统计学意义;放疗结束时与放疗后1个月的比较,P>,无统计学意义。结论:血清中cTnI的变化可早期反映放射性心脏损伤,以利于尽早预防和治疗放疗并发症和后遗症。【关键词】胸部肿瘤;放疗;心肌钙蛋白I;放射性心脏损伤StudyontheChangeofCardiacTroponinIofPatientswithChestTumorUnderRadiotherapyAbstract:ObjectiveToexploreanearlydiscoveryofbloodserummakerofmyocardialdamagewhentheheartwasexposedforc
