概括
斑块稳定,主要是通过降低脂质,通过改善血管壁的健康来减少冠心病事件. 然而,这个概念需要扩展,以解决不稳定和非脂质丰富的斑块,以全面预防心血管事件.
科学领域:
- 心血管医学 心血管医学
- 动脉样硬化研究 动脉样硬化研究
- 药理学 药理学是指药理学的学科.
背景情况:
- 斑块稳定概念解释了降脂疗法如何减少不良冠状动脉事件而没有显著的动脉样硬化回归.
- 降低脂质会在富含脂质的斑块中诱导有利的病理生物学变化,而这些斑块是急性冠状动脉事件的主要原因.
研究的目的:
- 评估斑块稳定概念的局限性.
- 探索对不稳定和非脂质丰富的斑块的治疗策略.
- 确定各种疗法减少未来急性冠状动脉事件的机制.
主要方法:
- 审查现有的关于斑块稳定和心血管事件减少的文献.
- 治疗方法的分析,包括降脂,皮肤干预,抗血栓和抗凝固疗法.
- 检查ACE抑制剂和β抑制剂在斑块稳定中的作用.
主要成果:
- 斑块稳定概念是有限的,因为它不能完全解决已经不稳定的斑块或非脂质丰富的斑块.
- 带有血栓的不稳定性斑块可能受益于皮肤干预,抗血栓剂,抗凝固剂或积极的脂质降低.
- 像ACE抑制剂,β抑制剂和抗血栓剂这样的疗法可以通过斑块稳定作用来部分减少事件.
结论:
- 斑块稳定概念需要改进,以涵盖更广泛的斑块类型和治疗干预措施.
- 综合性心血管事件预防需要针对富含脂质和非富含脂质斑块以及不稳定的病变的策略.
- 除了降脂剂之外,多种药物类别有助于减少心血管事件,可能是通过斑块稳定机制.

01:25Shape and Texture of Coarse Aggregate
Aggregate shape is classified based on the relative sharpness or roundness of the edges and corners. This classification includes categories like rounded, angular, elongated, and flaky, each with specific characteristics. Rounded aggregates, fully shaped by attrition, are typical of river or seashore gravel, while angular aggregates, such as crushed rock, have well-defined edges. Aggregates that are elongated and flaky are less desirable, as they can reduce the workability and strength of...
01:24Design Example: Aggregate Gradation
The right type and quality of aggregates are crucial for concrete as they significantly influence its properties, mix proportions, and cost-effectiveness. If different sources are available for sand, the commonly used fine aggregate in concrete, the selection of sand is primarily based on its gradation.
The grading, or particle-size distribution, of sand is determined using sieve analysis, with standard sizes ranging from 150 μm to 10 mm (ASTM No. 100 sieve to 3⁄8 in. sieve). Sand is sampled...
