儿科异常性肺动脉高血压的存活率通过通道阻塞剂 (CCB) 和epoprostenol得到改善. 早期治疗的成功率很高,但随着时间的推移而下降,这表明早期的移植评估是有益的.
科学领域:
- 儿童心脏病学 儿童心脏病学
- 肺部病理学 肺部病理学
- 医学研究 医学研究
背景情况:
- 儿童的异常性肺动脉高血压 (IPAH) 需要量身定制的治疗策略.
- 目前的治疗方法包括通道阻塞 (CCB) 治疗急性反应者,以及epoprostenol治疗不反应者.
研究的目的:
- 确定影响儿科IPAH患者生存和治疗成功的因素.
- 为了评估CCB和epoprostenol在这个人群中的长期疗效.
主要方法:
- 在1982年至1995年间,对77名被诊断患有IPAH的儿童进行了回顾性分析.
- 通过2002年收集的后续数据.
- 基于血管扩展剂应答 (CCB与epoprostenol) 和"近期医学时代"子集的治疗结果分析.
主要成果:
- 在接受CCB (97%,97%,81%) 和epoprostenol (94%,81%,61%) 治疗的组中,1,5年和10年的生存率都很高.
- 随着时间的推移,治疗成功率显著下降,特别是在5年后.
- 在最近的医学时代 (n=44),10年生存率为78%,治疗成功率为60%,诊断时的年龄预测了成功.
结论:
- 无论是CCB还是epoprostenol都改善了儿科IPAH的存活率.
- 随着时间的推移,治疗的成功率逐渐下降,这凸显了积极主动管理的必要性.
- 移植评估应在治疗过程的早期考虑,以防止失败.
