概括
支架后分流储备 (FFR) 可以预测心脏事件,但其预后价值在使用成像指导的最佳支架策略时是有限的. 这一策略优化了支架结果,减少了FFR对目标血管故障的影响.
科学领域:
- 心血管医学 心血管医学
- 干预性心脏病学 干预性心脏病学
- 医学成像医学成像
背景情况:
- 在用成像指导的最佳支架策略管理的患者中,支架后分流储备 (FFR) 的预后意义尚未得到充分确立.
- 最佳支架旨在通过仔细准备病变,尺寸支架,并执行后扩张来改善结果.
研究的目的:
- 为了评估在用冠心内成像指导的最佳支架策略 (iPSP) 治疗的患者中支架后FFR的预后价值.
- 确定iPSP策略是否会影响造血栓造血后FFR和长期造血栓造血栓结果之间的关系.
主要方法:
- 对来自IRIS-FFR注册表的1005名患者中的1108个病变进行了前性分析.
- 评估了支架后的FFR,主要结果是5年后的目标血管衰竭 (TVF),心脏死亡,目标血管心肌梗塞和目标血管再血管化的复合.
- 根据完整的iPSP策略 (损伤准备,支架大小,扩张后) 的应用,患者被分层.
主要成果:
- 在整体队列中,更低的静脉造后FFR显著与5年后TVF风险增加有关.
- 观察到,关于TVF风险的后造血FFR和iPSP策略之间存在显著的相互作用 (P=0.045).
- 在iPSP组中,造后的FFR没有预测TVF (aHR为1.00每0.01下降;P=0.95),而在没有iPSP组中,它仍然是一个显著的预测因素 (aHR为0.94每0.01下降;P=0.009).
结论:
- 支架后的FFR与心脏事件有关,证实了其对一般预后的相关性.
- 在实施全面的成像指导最佳支架策略 (iPSP) 后,支架后FFR的预后价值似乎减少了.
- 该iPSP策略可以减轻FFR的预后影响,表明其在优化支架放置和患者结果方面的有效性.

Conservation of Mass in Moving, Nondeforming Control Volume
Stormwater detention basins are essential in managing runoff during heavy rainfall, particularly in urban areas where impervious surfaces increase the risk of flooding. Understanding the conservation of mass in these systems allows engineers to optimize basin performance, balancing inflow, outflow, and water storage.
In the context of a detention basin, the conservation of mass states that the total mass of water entering the basin must equal the mass leaving the basin plus any accumulation of...

Design Example: Analyzing Capacity Contours for Flood Risk Assessment
Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...
