概括
在不进行生理学评估的情况下,推迟穿皮冠状动脉干预 (PCI) 对于中间冠状动脉病变导致3年后更多的严重心脏不良事件 (MACE). 与PCI相比,仅仅医疗疗就增加了复血管化需求.
科学领域:
- 心脏病学 心脏病学
- 干预心脏病学 干预心脏病学
- 临床试验 临床试验
背景情况:
- 在没有侵入性生理学评估的情况下,对中等冠状动脉病变推迟穿皮冠状动脉干预 (PCI) 的结果仍然不确定.
- 中级冠状动脉病变被定义为 50-70% 的直径狭窄通过血管学.
研究的目的:
- 在没有侵入性生理学评估的情况下,对中间冠状动脉病变进行医疗治疗和PCI之间的长期结果进行比较.
- 评估在经过保守治疗的患者和接受PCI的患者中发生重大心脏不良事件 (MACE) 的风险.
主要方法:
- 一个随机试验,涉及899名中等冠状动脉病变的患者.
- 患者被分配到一个保守的组 (推迟PCI) 或一个积极的组 (进行PCI).
- 主要终点是3年后的MACE (所有原因死亡,心肌梗塞或缺血驱动的再血管化).
主要成果:
- 保守组的MACE发病率在3年内明显高于积极组 (13.8%对9.3%,p=0.049).
- 这一差异主要是由于保守组的目标中间损伤再血管化增加 (6.5%与1.1%,p<0.001).
- 保守的组也显示了较高的心脏死亡或心脏病发作和缺血驱动的重血管化在1到3年之间的发病率.
结论:
- 单独用于中等冠状动脉病变的药物治疗,仅由血管造影指导,与3年后MACE的更高风险有关.
- 对中间病变进行PCI导致MACE较少,主要是由于减少了复血管化需求.
- 侵入性生理学评估对于指导中间冠状动脉病变的治疗决策至关重要.

Angina, also known as angina pectoris, is a chest pain resulting from diminished blood flow to the heart muscle and is often a symptom of coronary artery disease. Angina presents several variants with distinctive attributes, etiologies, and therapeutic approaches. The main types of angina include stable, unstable, variant (Prinzmetal's), microvascular, intractable, and silent ischemia.Stable angina is caused by atherosclerosis, which leads to the formation of plaques that narrow the coronary...
