概括

右心房水库菌株 (RARs) 可以预测系统性硬化症 (SSc) 患者的肺高血压 (PH). 这种心声回声测量可能有助于早期检测和管理SSc中的PH.

科学领域:

心脏病学心脏病学
类风湿病学类风湿病学
肺部病理学肺部病理学

背景情况:

系统性硬化症 (SSc) 患者需要定期查肺高血压 (PH).
在SSc中早期检测PH对于及时治疗肺动脉高血压 (PAH) 至关重要.
右心房 (RA) 功能在早期PH检测中的作用正在引起人们的注意.

研究的目的:

调查右心房储应变 (RARs) 是否可以作为早期右心脏过载的敏感指标.
确定RAR是否可以预测SSc患者未来PH的发展.

主要方法:

招募了113名SSc患者,并接受了综合性心声图.
测量的重点心声学参数包括肺动脉静脉压 (PASP),三环状平面静脉外流 (TAPSE) 和RARs.
患者的随访时间中位数为43个月,以监测PH的发展.

主要成果:

在113名患者中,有10名患者在随访期间发展出确定的PH.
多变量分析确定RAR是唯一独立的PH的心声学预测因子 (HR 0.85,p=0.01).
39.6的RARs截止值证明了预测值 (AUC0.7,p=0.04) 具有70%的灵敏度和60%的特异性.

结论:

右心房储菌株 (RARs) 显示出作为敏感的心声回声学标记物的潜力.
在患有全身性硬化症的患者中,RAR可以预测随后的肺高血压的发展.
这一发现可以改进早期识别和管理战略,用于SSc的PH.

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers

765

Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...

Coronary Artery Disease I: Introduction

1.8K

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...
