无金属置入物 药物直达血管壁 球囊也能带药治疗冠心病

2018-07-13 孙国根 健康报

历经 6 年攻关,由我国自主创新研发、国际首个批准用于冠状动脉分叉变病治疗的轻舟药物球囊,近日在上海市医学会、上海市医学会心血管病分会主办的第十二届东方心脏病学会议上获广泛好评。与会专家认为,该产品载药稳定,药物生物利用度高,其涂层工艺可确保药物快速均匀地释放至病变部位,一次短暂的接触(30 秒~60 秒)便能有效发挥抑制血管内膜增殖作用,为临床急需的分叉病变治疗提供了全新的治疗方案。目前,该产品

历经 6 年攻关,由我国自主创新研发、国际首个批准用于冠状动脉分叉变病治疗的轻舟药物球囊,近日在上海市医学会、上海市医学会心血管病分会主办的第十二届东方心脏病学会议上获广泛好评。与会专家认为,该产品载药稳定,药物生物利用度高,其涂层工艺可确保药物快速均匀地释放至病变部位,一次短暂的接触(30 秒~60 秒)便能有效发挥抑制血管内膜增殖作用,为临床急需的分叉病变治疗提供了全新的治疗方案。目前,该产品已获批上市。

据悉,冠状动脉分叉病变是指冠脉主支、分支部位分别或同时存在严重狭窄的病变,占所有经皮冠状动脉介入术的 15%~20%,一直是冠状动脉介入治疗的难点。专家介绍,经皮冠状动脉介入治疗已历经几代药物洗脱支架的应用,显着降低了术后血管病变处 1 年内的再狭窄发生率,但由药物洗脱支架置入带来的相关副作用也没有得到有效解决,如聚合物和金属支架本身会引起慢性炎症、晚期支架血栓、晚期再狭窄,需长期服用抗凝药物,以及导致局部血管生理功能丧失等问题。而轻舟药物球囊开创了冠脉介入“介入无植入”新治疗理念,即通过球囊扩张将表面携带的抗增殖药物(紫杉醇)释放至血管壁内,抑制血管平滑肌细胞增殖及内膜增生。该术式无金属置入物和聚合物残留体内,有利于减少患者体内血栓形成,避免长期置入物带来的一系列负面问题。

中国科学院院士、复旦大学附属中山医院心内科主任葛均波,在谈到从心脏支架到药物球囊的发展和前景时说,不敢说药物球囊会完全代替支架,但可以肯定,药物球囊会有自己的舞台,可为临床急需的分叉病变治疗提供新的治疗策略。
