Eur Heart J:抗癌治疗引起的心脏毒性分类、患病率和结局

2020-02-06 xing.T MedSci原创

由此可见,大多数患者在癌症治疗期间或之后出现了心肌损伤/功能障碍的客观数据。但是,严重的CTox具有很强的预后关系,发生相对较少。

心脏毒性(CTox)是癌症治疗的主要副作用,但缺乏指导临床和研究实践的统一诊断标准。近日,心血管领域权威杂志Eur Heart J上发表了一篇研究文章,研究人员前瞻性分析了865名患者,年龄为54.7±13.9岁,16.3%为男性,他们计划接受与中度/高CTox风险相关的抗癌治疗。

根据目前的指南,将进行性心肌损伤/功能障碍分为四组:正常、正常生物标志物(高敏感性肌钙蛋白T和利尿钠肽前体N端)和左心室(LV)功能(轻度、异常生物标志物)和/或左室功能障碍(LVD):左室射血分数(LVEF)≥50%;中度LVD,LVEF 40-49%;严重LVD,LVEF≤40%或有症状的心力衰竭。心脏毒性被定义为随访期间新的或从基线起心肌损害/心室功能恶化。患者中位随访时间为24个月。

在随访期间,在37.5%的患者中发现了心脏毒性[95%置信区间(CI)34.22–40.8%],轻度为31.6%,中度为2.8%,重度心肌损害/功能障碍为3.1%。严重的CTox组死亡率为每100名患者每年22.9例,而其余各组的死亡率为每100名患者每年2.3例,风险比为10.2(95%CI 5.5-19.2)(P<0.001)。

由此可见,大多数患者在癌症治疗期间或之后出现了心肌损伤/功能障碍的客观数据。但是,严重的CTox具有很强的预后关系,发生相对较少。
