被称为“心血管癌症”的肺高压有了新疗法!我国原创疗法登国际期刊

PADN-HF-PH研究成果登上《新英格兰医学杂志》,为晚期重症2型肺高压患者带来全新治疗选择

Quick Look

南京医科大学附属南京医院陈绍良团队与中国工程院院士韩雅玲牵头完成的PADN-HF-PH研究登上《新英格兰医学杂志》,证实肺动脉去神经术(PADN)联合标准药物治疗可显著降低2型肺高压患者的临床恶化风险达51%,填补了全球该领域的治疗空白。

Why It Matters

左心疾病引发的肺高压(2型肺高压)占所有肺高压患者的65%到80%,长期缺乏获批的特异性有效治疗手段。

很多心衰患者都有过这样的困惑:明明一直在按时吃药,怎么稍微一活动就喘得厉害?其实,这背后很可能隐藏着一位“隐形杀手”——2型肺高压。2016年《欧洲心脏杂志》数据显示,由左心疾病引发的肺高压(2型肺高压),占到了所有肺高压患者群的65%~80%。

长期以来,针对这类患者,临床上一直缺少获批的特异性有效治疗手段,是心血管领域公认的难题。而如今,一项中国原创技术,正在打破这个僵局。

日前,在2026欧洲心脏病学会年会(ESC2026)上,肺动脉去神经术(PADN)发明人、南京医科大学附属南京医院陈绍良主任医师受邀做专题报告,分享PADN治疗心衰相关肺高压的研究成果,该研究同步刊发于《新英格兰医学杂志》。中国工程院院士、本研究论文共同通讯作者、PADN-HF-PH国内多中心研究牵头人韩雅玲表示:“这项研究为临床医生提供了高级别循证依据,有望推动国内外心血管指南更新,给晚期重症2型肺高压患者,带来安全有效的全新治疗选择。”

当心衰遇上肺高压

被称为“令人绝望的心血管癌症”

肺高压,常被称为“心血管领域的癌症”,是一种恶性血管疾病。当心衰合并肺高压,被国内肺高压专家共识认定为预后极差的高危状态。作为左心疾病所致肺高压,它不仅是5种类型肺高压中患病人群最庞大、发病率最高的类型,也是导致心血管疾病患者死亡的重要危险因素之一。

韩雅玲院士介绍,左心泵血无力,血液淤积在肺循环,长期压力升高会让肺部小血管增厚、变硬,肺血管阻力不可逆升高,这会大幅增加右心室泵血负荷;右心室本就是“低压泵”,如果长期对抗较大阻力,会逐步肥厚、扩张直至衰竭,还会挤压室间隔反过来干扰左心室充盈,形成恶性循环,最终可能发展为全心衰竭,伴随缺氧、多器官损伤、恶性心律失常等。此时患者心脏储备基本耗尽,轻微刺激就可能诱发急性危重事件,也是权威指南明确标注的心衰重要不良预后标志。

面对如此凶险的病情,临床治疗却常常陷入“无计可施”的困境。韩雅玲院士坦言,“目前我们在治疗上遇到的最大难处是,尽管国内外心衰诊治指南推荐的标准药物治疗(GDMT),能够一定程度上改善心衰的整体预后,但是针对心衰合并肺高压这一特定肺血管病变患者群,依然缺乏特异性的、正式获批的有效干预手段。传统的、针对一型肺高压的靶向药物并不适合此类患者,导致治疗难度大,患者病情往往难以控制,会频繁因心衰加重而反复住院,生活质量差,死亡率非常高。”

这项原创技术填补全球空白

给患者带来新希望

为了填补2型肺高压长期缺乏有效干预手段的技术空白,韩雅玲院士担任主要研究者,带领团队开展了PADN-HF-PH临床研究,在全国25家临床中心共入组264名患者,旨在评估肺动脉去神经术治疗左心衰竭相关肺高压的安全性与有效性。

“我们希望通过严谨的随机对照设计科学地验证:在标准药物治疗基础上,联合我国专家原创的肺动脉去神经术,能够安全有效地从源头上阻断交感神经过度激活,切实降低患者增高的肺动脉压力。”韩雅玲院士表示,研究的核心目标,是要证明这项创新技术不仅能改善患者短期的血流动力学指标,还能缓解患者中长期的病情恶化和减少反复住院,改善他们的实际预后,从而破解心衰防治中的这个临床瓶颈。

对比指南推荐的标准药物治疗

恶化风险降低51%

韩雅玲介绍,作为一项创新的介入技术,PADN在临床的应用必须是精准且严谨的。结合PADN-HF-PH研究设定了严格的入选标准,最适合接受这项治疗的患者须同时满足以下几个条件:基础药物治疗达标、心功能与活动耐量出现明显受损、血流动力学指标的异常达到诊断肺高压的国际指南要求。符合上述情况的射血分数保留或降低的心力衰竭患者、瓣膜性心脏病已接受换瓣治疗但仍合并肺高压的患者,均可以考虑PADN治疗。

韩雅玲表示,该技术不能完全替代药物,而是与药物治疗共同采用,形成“微创介入加上药物治疗”的双重疗法,它给患者带来的益处是显著的:

1. 安全性方面:PADN-HF-PH研究显示手术创伤小、恢复快,除了极少数出现穿刺部位血肿外,未发生其他手术并发症,随访期间整体安全性表现理想。

2. 临床获益方面:PADN-HF-PH研究显示,在GDMT基础上联合PADN,校正后,2年随访PADN联合GDMT组的临床恶化发生率为25.7%,临床恶化风险降低51%(HR 0.49,95% CI 0.30–0.82;P=0.006)。PADN联合GDMT使患者年化临床恶化事件复发率下降35.5%。同时,术后12个月时,PADN联合GDMT组患者6分钟步行距离较对照组净增加24.8米,提示患者运动耐量与功能状态获得进一步改善。

20多年前开始,面对我国冠心病患者治疗效果和性价比不够理想的困境,韩雅玲院士牵头开展CREATE、BRIGHT等系列研究;20多年后,助力中国自主研发的原创器械和技术发表于国际顶级学术期刊,为万千患者带来实实在在的获益。韩雅玲院士说:“作为一名中国心血管医生,我感到非常自豪。只要这项技术能够真正有助于解决患者的临床痛点,我们就必须具备用最高临床研究标准去验证的决心、耐心与信心,克服艰难险阻走下去,直至问题得到解决。”

Open Questions

  • 该技术未来是否会在全球更多医疗中心广泛推广?
  • 国内心血管指南何时会正式更新以纳入该疗法?
