概括

一个新的床边工具,后循环缺血性中风得分 (PCS-SCORE),可以使用简单的临床特征来识别后循环缺血性中风 (PCS) 的患者. 这一分数有助于早期检测和风险分层对这种具有挑战性的条件.

科学领域:

神经学神经学
临床诊断临床诊断临床诊断
脑卒中医学脑卒中医学

背景情况:

由于不典型的症状,后循环缺血性中风 (PCS) 的诊断不足.
早期发现PCS至关重要,但具有挑战性.
传统的中风尺度往往无法充分代表PCS.

研究的目的:

开发一个实用的临床评分工具,PCS-SCORE.
使用床边特征识别PCS高风险患者.
为了改善后部循环缺血性中风的早期识别.

主要方法:

从中风登记册中回顾分析了5163名患者 (1571名确诊PCS).
使用多变量逻辑回归和拉索建模识别关键预测因素.
基于加权变量的PCS-SCORE (0-9分) 的发展:糖尿病,高血压,男性性别,双重/模糊视力,随吐的头和失调.

主要成果:

PCS-SCORE在>3的值 (87.9%的特异性,43.4%的灵敏性) 上显示了0.76的AUC.
将值提高到>4,使得特异性提高到94.4% (灵敏度为27.9%).
较高的分数与PCS的可能性增加相关,有助于风险识别.

结论:

PCS-SCORE是一个简单的,高度特定的床头工具,用于早期检测后部循环中风.
它的统治实力在医院前和紧急情况下是有价值的.
目前正在进行PCS-SCORE的前性验证.

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...
