概括
通过心声学测量的左心房体积指数 (LAVi) 和LA应变 (LASct) 可以预测源不明患者的栓塞性中风中的心房动 (AF). 这些指标可能有助于选择受益于循环记录器监测AF的患者.
科学领域:
- 心脏病学
- 神经学
- 医学成像
背景情况:
- 动性心房动 (AF) 是源不明的栓塞性中风 (ESUS) 的潜在原因.
- 循环记录器 (LR) 检测AF,但在ESUS患者中广泛使用可能不具有成本效益.
- 通过斑点追踪心声学 (STE) 评估左心房功能,可以确定ESUS患者可能受益于LR监测.
研究的目的:
- 评估通过STE评估的LA功能是否可以识别ESUS患者,这些患者可以从LR监测中获益.
- 确定LA功能参数在ESUS患者中发生AF的预测值.
主要方法:
- 在2020年至2023年间连续接受LR植入和心声扫描 (包括STE) 的ESUS患者被纳入.
- 患者根据LR检测的AF分组在中位数为10. 0个月的随访期间.
- 使用STE测量左心室体积指数 (LAVi) 和LA纵向应变 (LASr,LASct).
主要成果:
- 包括64名患者:有27名 (42. 2%) 患有肌,有37名 (57. 8%) 没有肌.
- 与非肌肉发作组相比,肌肉发作组的LAVi (44. 7 vs. 34. 4 mL/ m2) 和LASr (19. 7% vs. 27. 4%) 和LASct (7. 4% vs.
- 多变量分析发现LAVi和LASct是AF的独立预测因子.
结论:
- 左心室体积指数 (LAVi) 和左心室收缩压力 (LASct) 是ESUS患者心脏病的可靠预测指标.
- 这些心声学参数可能有助于选择最有可能从循环记录器植入用于AF检测中受益的ESUS患者.

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias
160
Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests
52
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

Disturbances in Heart Rhythm
1.2K
Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow heart...

Mitral Stenosis I: Introduction
34
Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...

Mechanism of Cardiac Arrhythmias
1.1K
Arrhythmias are irregular heart rhythms occurring when the heart's electrical impulses become abnormal. These disturbances can lead to various symptoms, depending on their severity and the underlying cause. Some common factors contributing to arrhythmias include hypoxia, ischemia, electrolyte imbalances, excessive catecholamine exposure, drug toxicity, and muscle overstretching. Arrhythmias can be classified into two main types based on the rate and site of origin of abnormal heart rhythms.
