CIRC RES:可可粉改善外周动脉疾病老年人步行能力

2020-02-17 xing.T MedSci原创

由此可见,这些初步结果表明可可粉对PAD患者的步行能力具有治疗作用。需要进一步研究以明确可可粉是否能显著改善PAD患者的行走能力。

可可及其主要成分表儿茶素具有治疗特性,可改善下肢周围动脉疾病(PAD)患者的肢体灌注并增加小腿肌肉线粒体活性。近日,心血管领域权威杂志Circulation Research上针对这些问题发表了一篇研究文章,这项II期随机临床试验中,研究人员旨在评估与安慰剂相比,服用六个月的可可粉能否改善PAD患者的行走能力。

在这项为期六个月的双盲随机临床试验中,PAD参与者随机分为可可饮料组和安慰剂饮料组。可可饮料组受试者每天摄入15g可可和75mg表儿茶素。安慰剂组既不含可可也不含表儿茶素。该研究的两个主要结局分别是在6个月的随访中服用研究饮料后2.5小时和24小时后六分钟步行距离的变化值。单侧P值<0.10被认为具有统计学意义。

在随机分组的44名PAD参与者中(平均年龄为72.3岁(+7.1),平均踝臂指数为0.66(+0.15)),有40名(91%)参与者完成了随访。根据吸烟、种族和体重指数进行调整,在6个月的随访中,与安慰剂相比,可可粉组2.5小时后的6分钟步行距离提高了42.6米(90%置信区间(CI):+ 22.2,+∞,P=0.005),24小时后步行距离提高了18.0米(90%CI:-1.7,+∞,P=0.12)。在小腿肌肉活检中,与安慰剂相比,可可粉改善了线粒体细胞色素C氧化酶活性(P=0.013),增加了毛细血管密度(P=0.014),改善了小腿肌肉灌注(P=0.098)。

由此可见,这些初步结果表明可可粉对PAD患者的步行能力具有治疗作用。需要进一步研究以明确可可粉是否能显著改善PAD患者的行走能力。
