在功能上显著的冠状动脉病变中,可使用回拉压梯度 (PPG) 和分数流量储备 (FFR) 测量来预测脆弱斑块. 这种组合可以准确地识别高风险斑块,而不需要进一步的解剖或斑块成像.
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:
- 易受伤害的斑块对于预测心血管事件至关重要.
- 在功能显著的病变中识别易受损的斑块在临床上很重要.
研究的目的:
- 识别功能性显著的冠状动脉病变中的易受损伤斑的预测因子.
- 评估回拉压梯度 (PPG) 和分量流量储备 (FFR) 在预测易受损伤的斑块中的作用.
主要方法:
- 一项前性多中心研究,涉及95名FFR≤0.80.0的患者.
- 冠状动脉计算机断层扫描血管造影和光学连贯性断层扫描用于斑块分析.
- 分析了PPG和FFR数据以及临床和血管学发现.
主要成果:
- 在55.8%的病变中存在脆弱斑块.
- 无论是PPG还是FFR都是脆弱斑块 (P <0.05) 的显著预测因素.
- 组合PPG>0.65和FFR ≤0.70显示了易受损伤的斑块 (88.2%) 的最高流行率.
结论:
- 与FFR结合的PPG可以预测低FFR病变中的脆弱斑块.
- 预测不需要任何额外的解剖学或斑块特征.
- 这种方法有助于识别高风险冠状动脉病变.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
Loss of Tumor Suppressor Gene Functions
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
