在预测急性冠状动脉综合征患者左心室功能障碍时,非侵入性心肌工作和全身炎症评估的有用性
在PubMed上查看摘要
概括
此摘要是机器生成的。炎症标志物C反应蛋白 (CRP) 在急性冠状动脉综合征 (ACS) 中与心肌工作 (MW) 参数相关,表明未来左心室 (LV) 功能障碍和心力衰竭的可能性.
科学领域
- 心脏病学
- 生物标志物
- 心声检查
背景情况
- 左心室 (LV) 改造是急性冠状动脉综合征 (ACS) 后心力衰竭 (HF) 病理生理学的核心.
- 传统的测量方法,如喷射分数 (LVEF) 和体积,以及斑点跟踪心声学 (STE),评估LV性能.
- 心肌工作 (MW) 提供了一种新的非侵入性方法,通过整合负载条件来检测心肌功能障碍.
研究的目的
- 在ACS患者中研究心肌工作 (MW),高灵敏度素I (hs- cTn I) 和C反应蛋白 (CRP) 之间的关系.
- 评估MW,hs-cTn I和CRP作为ACS后LV功能障碍的潜在早期预测因素.
主要方法
- 在ACS入院后24小时内进行了带有斑点跟踪和MW测量的心声扫描.
- 同时评估了hs- cTn I和CRP水平.
- 在6至8周的随访期内重复临床,生物和心声评估.
主要成果
- 基线hs- cTn I与全球纵向应变 (GLS) 和MW参数 (GWI,GCW) 相相关,但没有LVEF.
- 尽管与LVEF无相关性,但C反应蛋白 (CRP) 与MW参数 (GWE,GWW) 有显著的相关性.
- 较高的CRP水平 (> 28 mg/ L) 与MW性能 (GWE) 的降低有关,这表明有不利的LV重塑的倾向.
结论
- 在ACS发生后24小时内,C反应蛋白 (CRP) 水平及其与MW参数的相关性可能预测未来的LV功能障碍.
- 这突显了结合炎症标志物与先进心声学技术的潜力,以早期分层风险.

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...
Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...
Myocarditis is inflammation of the myocardium, which is the muscular layer of the heart.EtiologyMyocarditis has a diverse etiology, including a wide range of infectious and non-infectious causes:Infectious CausesViral: Common viruses include Coxsackie A and B, adenovirus, parvovirus B19, enteroviruses, and influenza A.Bacterial: Examples include infections caused by Streptococcus, Staphylococcus, and Mycoplasma species.Rickettsial: Infections like Rocky Mountain spotted fever can result in...
The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...
Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...
