概括
肌区域 (PMA) 和多叶膜溢出预测了通过导管大动脉植入 (TAVI) 后的心血管死亡率. 虽然这些放射性标记物具有预后价值,但它们的组合包含在预测患者结果的EuroSCORE II模型上提供了适度的改进.
科学领域:
- 心脏病学 心脏病学
- 放射学 放射学是一门学科.
- 医疗成像医学成像
背景情况:
- 过导管大动脉植入 (TAVI) 是对大动脉狭窄的常见程序.
- 放射性标记物,如psoas 肌肉区域 (PMA) 和肺部溢液,是死亡率的潜在预测因素.
- 这些标志物在TAVI后因特定原因死亡率的预后价值需要进一步调查.
研究的目的:
- 为了调查 psoas 肌肉区域 (PMA) 和肺部溢液与 TAVI 后因特定原因死亡率之间的关联.
- 评估超出EuroSCORE II风险模型的PMA和胸腔溢液的增量预后值.
主要方法:
- 对1090名TAVI患者 (2008-2020年) 的回顾性分析.
- 在手术前的CT扫描中,评估了L3级的PMA和多流液.
- 用分发危险模型和时间依赖歧视指数 (AUC,IDI,NRI) 来进行分析.
主要成果:
- 在TAVI后,PMA和流与心血管死亡率显著相关 (PMA:p=0.037;流:p<0.001).
- 没有发现与非心血管或非自然死亡原因有显著的关联.
- 与单独的EuroSCORE II相比,组合PMA和多叶膜溢出改善了预测模型 (NRI=0.13,IDI=0.015).
结论:
- 肌区域和膜溢出是TAVI后心血管死亡的独立预测因素.
- 这些标志物并不能显著预测非心血管死亡率.
- 虽然在统计学上显著,但PMA和肺流的联合含量在EuroSCORE II之外的死亡率预测中提供了适度的,但在临床上没有意义的改善.

Pleural Effusion I: Introduction
4.3K
Pleural effusion is an abnormal fluid accumulation in the pleural cavity, a narrow space between the lungs and the chest wall. It is not a disease per se but rather a symptom or indication of an underlying disease. In normal circumstances, this space contains a small amount of fluid (5 to 15 mL), a lubricant facilitating the non-frictional movement of the pleural surfaces.

Pleural Effusion Overview
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.

Behavior of Gas Molecules: Molecular Diffusion, Mean Free Path, and Effusion
31.3K
Although gaseous molecules travel at tremendous speeds (hundreds of meters per second), they collide with other gaseous molecules and travel in many different directions before reaching the desired target. At room temperature, a gaseous molecule will experience billions of collisions per second. The mean free path is the average distance a molecule travels between collisions. The mean free path increases with decreasing pressure; in general, the mean free path for a gaseous molecule will be...

Pleural Disorders: Types and Brief Description

The pleura is a vital part of the respiratory system. It's a double-layered membrane surrounding the lungs and lining the chest cavity. The two layers of the pleura are:

Classification of Skeletal Muscle Fibers
59.5K
Skeletal muscles continuously produce ATP to provide the energy that enables muscle contractions. Skeletal muscle fibers can be categorized into three types based on differences in their contraction speed and how they produce ATP, as well as physical differences related to these factors. Most human muscles contain all three muscle fiber types, albeit in varying proportions.

Muscles of the Eye
4.3K
The muscles of the eye are sophisticated structures that control eye movement and focus, allowing for the precise and rapid adjustments necessary for vision. The human eye is controlled by ten muscles — six extraocular muscles, three intraocular muscles, and one primary eyelid retractor muscle.
Extraocular Muscles
The six extraocular muscles surround the eyeball and control its movements. They are responsible for a wide range of eye motions, including looking up, down, left, right, and...
