概括
扩散性冠状动脉疾病 (CAD) 对皮肤冠状动脉干预 (PCI) 的结果产生负面影响. 分散的CAD模式独立地预测不良的即时结果,并增加PCI后预测的2年不良事件.
科学领域:
- 心血管医学 心血管医学
- 干预心脏病学 干预心脏病学
- 医疗成像医学成像
背景情况:
- 扩散性冠状动脉疾病 (CAD) 给皮肤冠状动脉干预 (PCI) 带来了挑战.
- 定量流量比 (QFR) 提供了对CAD严重性的生理评估.
- 了解分散的CAD模式对PCI结果的影响至关重要.
研究的目的:
- 评估QFR评估的扩散性CAD模式对PCI后立即血液动力学结果的影响.
- 为了确定分散的CAD模式是否会影响预测的2年船舶导向复合终点 (VOCE).
主要方法:
- 从多血管TALENT (MVT) 试验中,对503名患者和1022个血管进行了手术前配对QFR的分析.
- 将CAD模式分类为"主要扩散"或"焦点",使用虚拟QFR回拉压力梯度 (PPG) 指数.
- 使用每毫米的QFR梯度 (dQFR/ds) 和定义为≥0.91.1.的最佳PCI后QFR来评估"主要梯度".
主要成果:
- "主要扩散"CAD的患病率为68.6%.
- 具有主要梯度的分散CAD增加了PCI后低于最佳QFR的风险 (OR 1.52).
- 低QFR PPG指数 (扩散性疾病) 是PCI后低于最佳QFR的独立预测指标 (或9.8每0.1下降).
- 预测的2年VOCE在扩散性 (6.1%) 与焦点性 (4.2%) 病变中更高.
结论:
- 术前扩散的CAD模式是PCI后不利的立即血液动力学结果的独立预测因素.
- 扩散性CAD对预测的2年血管导向复合终点产生不利影响.
- 来自QFR的生理评估有助于了解分散的CAD对PCI成功和长期预后的影响.

Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and...

The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...
