概括
减少左心房应变 (LAS) 与冠状动脉栓塞 (CE) 患者的病情恶化有关,这是心脏病发作的罕见原因. 这一发现表明,LAS可以帮助预测CE患者的预后.
科学领域:
- 心脏病学 心脏病学
- 心声回声扫描 (Echocardiography) 是一种心声回声扫描.
- 心血管成像 - 心血管成像
背景情况:
- 冠状动脉栓塞 (CE) 是急性心肌梗塞 (AMI) 的不常见原因,约占病例的3%.
- 左心房应变 (LAS) 是心房功能的敏感指标,但其在CE的预后价值尚未确立.
研究的目的:
- 在被诊断为冠状动脉栓塞 (CE) 的患者中研究左心房应变 (LAS) 的预后作用.
- 评估LAS减少和CE患者的住院和长期不良结果之间的关联.
主要方法:
- 对100名连续患有CE的患者的回顾性分析,诊断使用临床,血管学和成像学标准.
- 评估住院事件和长期结果 (平均随访26个月).
- 多变量分析以确定不良结果的独立预测因子,包括LAS储,心房动 (AF) 和右心室功能障碍 (RVD).
主要成果:
- 减少的LAS储备是医院不良结果 (OR 0.88,P=0.03) 和长期不良结果 (HR 0.9,P=0.02) 的独立预测因素.
- 前庭动 (AF) 和右心室功能障碍 (RVD) 也是住院事件的独立预测因素.
- 一个LAS储存器切断值<17.5%与显著更高的长期不良结果风险相关 (P<0.001).
结论:
- 降低左心房压力与冠状动脉栓塞患者在医院和长期结果的恶化显著相关.

Mitral Stenosis I: Introduction
485
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...

Acute Coronary Syndrome III: Diagnostic Studies
219
Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Imbalances in Cardiac Output
2.3K
The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...

Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...

Cardiomyopathy III: Hypertrophic Cardiomyopathy
416
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests
420
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...
