概括
在患有心房动 (AF) 和没有心房动 (AF) 的密码性中风患者中,心房斑块的分布不同. 斜侧斑 ≥1.4mm 可能预测没有AF,暗示其他栓塞来源.
科学领域:
- 心脏病学 心脏病学
- 神经学 神经学
- 血管医学 血管医学
背景情况:
- 密码性中风 (CS) 占缺血性中风的很大一部分.
- 前庭动 (AF) 是CS的常见原因,但其检测可能具有挑战性.
- 了解中风病因对于有效的预防策略至关重要.
研究的目的:
- 为了确定心血管斑块大小不对称是否会影响CS患者的AF检测.
- 探讨两侧和两侧带斑块分布和AF发生之间的关系.
- 在CS中识别非AF栓塞源的潜在预测因素.
主要方法:
- 从多中心LOOK研究中分析前性数据.
- 包括通过植入式心脏监测器 (ICM) 监测的单边前循环脑梗塞患者.
- 与中风部位相对较的ipsilateral和contralateral侧之间带斑块大小的比较,通过在6个月内检测AF进行分层.
主要成果:
- 包括97名CS患者;21人发展了AF.
- 没有检测到AF的患者显示,与相反侧面 (p=0.022) 相比,异侧侧侧侧侧侧侧侧侧侧侧侧侧侧侧侧侧侧侧侧侧侧侧侧侧 (≥1.4毫米) 斑块的发生频率明显高.
- 一个ipsilateral-to-contralateral斑块大小比率≥1.2预测没有检测到AF与75%的特异性和63%的灵敏度 (AUC=0.727).
结论:
- 冠状动脉斑块的分布模式在有或没有检测到AF的CS患者之间有所不同.
- 一个≥1.4mm和≥1.2的尺寸比可以预测没有检测到的AF.
- 这些发现表明,非对称的状动脉斑块分布可能表明CS中的AF以外的栓塞来源.

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...

Coronary Artery Disease I: Introduction

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...
