概括
穿皮冠状动脉干预 (PCI) 有效地减少了所有年龄组的稳定患者的胸痛频率. 然而,它对运动能力的益处在老年人中不那么明显,这表明需要重新评估试验终点.
科学领域:
- 心脏病学 心脏病学
- 干预心脏病学 干预心脏病学
- 临床试验 临床试验
背景情况:
- 在ORBITA-2试验中,通过皮肤冠状动脉干预 (PCI) 证明了在没有抗心血管药物的情况下稳定心痛患者的疗效.
- 不同年龄人口群体中PCI影响的一致性仍未得到检查.
研究的目的:
- 为了研究患者年龄和症状/缩水症严重程度之间的相互作用.
- 评估PCI对与年龄相关的初级和二级终点的疗效.
主要方法:
- 对所有ORBITA-2试验参与者的后期分析.
- 对日常症状的贝叶斯纵向马尔科夫模型.
- 贝叶斯正则比例赔率模型用于炼时间,压力心声和问卷,结合年龄相互作用.
主要成果:
- 与年轻患者 (OR: 1.70) 相比,PCI在老年患者中显著改善了症状缓解 (OR: 2.03).
- PCI对跑步机炼时间的影响在年轻人中显著更大 (50岁时为125秒),而不是老年人 (70岁时为31.9秒).
- 没有观察到年龄和症状或狭窄症严重程度之间的显著关系.
结论:
- 在稳定的冠状动脉疾病中,PCI在所有年龄段有效减少心肌痛症状.
- 在老年人中,运动耐受性的有限改善表明跑步机的时间可能不是抗风脉试验的最佳初级终点.
- 结果支持包括年龄在内的心血管试验设计和终点选择.

Pharmacodynamics in Geriatric Patients: Effects of Age
202
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

Secondary Active Transport
137.7K
One example of how cells use the energy contained in electrochemical gradients is demonstrated by glucose transport into cells. The ion vital to this process is sodium (Na+), which is typically present in higher concentrations extracellularly than in the cytosol. Such a concentration difference is due, in part, to the action of an enzyme “pump” embedded in the cellular membrane that actively expels Na+ from a cell. Importantly, as this pump contributes to the high concentration of...

Secondary Healthcare System
2.0K
Secondary healthcare is offered by a specialist, generally in hospitals or clinics for patients referred by primary healthcare providers. It occurs when a person has an illness or injury that requires specific medical care. Secondary care is often referred to as acute care. Secondary care can range from uncomplicated care to repair a minor laceration or treat a strep throat infection to more complicated emergent care, such as treating a head injury sustained in an automobile accident.

Primary and Secondary Growth in Roots and Shoots
60.4K
Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.

Association Areas of the Cortex
9.2K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...
