NEJM:顽固性心绞痛患者的福音来了

顽固性心绞痛患者的福音来了背景许多有冠心病的患者并不适合使用血管再生药物进行治疗顽固性心绞痛,尽管这一措施符合治疗标准。我们使用了一个利用气囊膨胀原理、不锈钢、沙漏形、减少冠状窦的新设备,将该设备放置在一个冠状窦最集中狭窄的部位,增加冠状窦压力,血液也因此分配到缺血心肌,采用这个原理治疗顽固性心绞痛。方式实验参与人员为104位由加拿大心血管协会(CCS)评定心功能为三级或者四级和心肌缺血的患者(心

背景:


许多有冠心病的患者并不适合使用血管再生药物进行治疗顽固性心绞痛,尽管这一措施符合治疗标准。我们使用了一个利用气囊膨胀原理、不锈钢、沙漏形、减少冠状窦的新设备,将该设备放置在一个冠状窦最集中狭窄的部位,增加冠状窦压力,血液也因此分配到缺血心肌,采用这个原理治疗顽固性心绞痛。

方式:

实验参与人员为104位由加拿大心血管协会(CCS)评定心功能为三级或者四级和心肌缺血的患者(心功能分为一级至四级,评分等级越高表明由心绞痛导致的日常生活能力受限越大),他们都没有接受血管再生治疗,我们随机分配参与人员为实验组或者对照组,实验组和对照组各54名。实验组的成员使用新设备治疗狭窄性冠脉窦,以增加冠状窦压力,使血液分配到缺血心肌。对照组接受采用普通治疗方式。主要目的探究6个月内实验组和对照组中心绞痛患者至少得到两个CCS心功能等级的改善的比例,即心功能由三级或者四级改善为一级或者二级。

结果:

实验结果表明,在实验组中一共有18名心绞痛患者在6个月中至少有两个CCS心功能等级的改善,占实验组总人数的35%,而对照组则有8位心功能等级有至少两个层次的改善,仅占对照组总人数的15%。(P=0.02)通过使用新设备进而使心功能等级得到至少一个层次的改善的患者有37位,占实验组患者的71%,而对照组中有22位患者使心功能等级得到至少一个层次,占对照组患者的42%。(P=0.003)我们通过使用西雅图心绞痛量表评估日常生活能力及生活质量,结果表明,相比对照组而言,实验组的患者通过使用新设备,生活质量及日常生活能力有很大的提高及改进。(我们使用的评估量表是一个满分为100分的西雅图心绞痛量表,通过评分得出,实验组平均得分为17.6,对照组平均得分7.6分,P=0.03)通过使用多巴酚丁胺并且做超声心动图,我们得知两组患者在运动时间及心室壁运动指数平均变化方面无明显区别。6个月内,实验组的一名患者发生了心肌梗死;而对照组则有一名患者死亡,并有三名患者发生了心肌梗死。

结论:

通过使用小规模的临床试验我们得知,通过移植安装这种可以减少冠状窦的设备到不使用药物进行血管再生治疗的心绞痛患者体内,可以显著提高顽固性心绞痛患者的生活质量,可明显改善心绞痛的病情。它的前景是很好的,是顽固性心绞痛患者的福音。
