概括
设备检测的亚临床心房动 (SCAF) 是常见的. 在ARTESIA研究中,阿皮克萨班显示中风风险降低了37%,但增加了出血,需要小心选择患者接受抗凝治疗.
科学领域:
- 心脏病学 心脏病学
- 神经学 神经学
- 药理学 药理学是指药理学的学科.
背景情况:
- 由于心脏植入式电子设备和智能手表的广泛使用,设备检测的亚临床心房动 (SCAF) 越来越普遍.
- 根据定义和设备,SCAF检测率有所不同 (30-60%),加密性中风患者通过长时间监测的比率更高.
- 在SCAF中,中风风险取决于CHA2DS2-VASc得分和发作的持续时间,而>24小时的发作显著增加了风险.
研究的目的:
- 审查通过设备检测的亚临床心房动 (SCAF) 的发生率,中风风险和管理策略.
- 评估最近关于SCAF直接口服抗凝剂 (DOAC) 的临床试验数据及其对当前指导方针的影响.
- 讨论SCAF抗凝治疗的不断变化的格局,考虑患者的风险因素和试验结果.
主要方法:
- 对现有的文献和临床试验进行了审查 (EMBRACE,Crystal-AF,Find-AF,ASSERT,NAVIGATE-ESUS,RE-SPECT ESUS,NOAH-AFNET 6,ARTESIA).这些试验的结果是:
- 分析与SCAF相关的中风风险因素,包括CHA2DS2-VASc得分和发作持续时间.
- 根据新证据评估当前的ACC/AHA指导方针,并提出基于新证据的重新评估.
主要成果:
- 在SCAF的ARTESIA研究中,阿皮克萨班表明中风/SE风险降低了37%,但出血事件增加.
- 以前的DOAC试验 (NAVIGATE-ESUS,RE-SPECT ESUS) 在密码性中风中没有显示出对阿司匹林的优越性.
- NOAH-AFNET 6试验因徒劳而提前终止;由于DOAC类型,试验设计和患者群体而导致不同的结果.
结论:
- 目前的指导方针建议口服抗凝药 (OAC) 用于SCAF>24小时 (CHA2DS2-VASc>2) 或6-24小时 (CHA2DS2-VASc>3),并控制其他风险因素.
- 积极的ARTESIA结果表明,可能需要重新评估OAC的适用性,特别是对于高风险患者 (CHA2DS2-VASc>4,先前中风).
- 对高出血风险患者来说,优化可修改的出血风险因素至关重要;正在进行的试验将进一步澄清SCAF管理.

Amyloid Fibrils
11.9K
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining,...

Fibril-associated Collagen
3.4K
Fibril-associated collagens are a type of collagens present in the extracellular matrix with interrupted triple helices or FACIT (Fibril-associated collagens interrupted triple-helices). FACIT help connect and attach the collagen fibrils with each other as well as with other proteins of the extracellular matrix.
For example, the type II collagen fibrils in cartilage have covalently bound type IX fibril-associated collagens at regular intervals. Other types of fibril-associated collagens are...

Clinical Trials: Overview
4.9K
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...

Trial and Error and Algorithm
404
A problem-solving strategy is a plan of action used to find a solution. Different strategies have distinct action plans. Trial and error involves trying different solutions until one works. For instance, to fix a broken printer, you might check ink levels, ensure the paper tray isn't jammed, and verify the printer's connection to your laptop. This method can be time-consuming but is commonly used. Thomas Edison, for example, used trial and error to find a suitable filament for the light...

Clinical Trials
10.4K
Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.
