JACC:卡维地洛可用于预防化疗引起的心脏毒性

2018-05-16 MedSci MedSci原创

蒽环霉素(ANT)化疗有一定的心脏毒性,β受体阻滞剂预防该心脏毒性的效果尚存在争议。本研究的目的旨在通过随机双盲对照试验评估卡维地洛在预防ANT致心脏毒性中的作用。本研究纳入了200例HER2阴性且左室射血分数正常的接受ANT化疗的乳腺癌患者,并将其随机分成卡维地洛治疗组和安慰剂组,主要终点事件是6个月内LVEF减少10%以上,次要终点事件是卡维地洛对肌钙蛋白I和B型钠尿肽的影响和心脏舒张功能不全

蒽环霉素(ANT)化疗有一定的心脏毒性,β受体阻滞剂预防该心脏毒性的效果尚存在争议。本研究的目的旨在通过随机双盲对照试验评估卡维地洛在预防ANT致心脏毒性中的作用。

本研究纳入了200例HER2阴性且左室射血分数正常的接受ANT化疗的乳腺癌患者,并将其随机分成卡维地洛治疗组和安慰剂组,主要终点事件是6个月内LVEF减少10%以上,次要终点事件是卡维地洛对肌钙蛋白I和B型钠尿肽的影响和心脏舒张功能不全。分析结果显示,主要终点事件在卡维地洛组和安慰剂组的发生率分别是14.5%和13.5%(p=1.0),两组间左室射血分数和B型钠尿肽的变化无明显差异,但是卡维地洛组的肌钙蛋白I水平明显更低(p=0.003),另外,心脏舒张功能不全的发生率在卡维地洛组中也更低(p=0.039)。

本研究结果显示,卡维地洛对蒽环霉素化疗患者的左室射血分数无明显影响,但是可以降低患者肌钙蛋白I的水平和心脏舒张功能不全的发生率。
