概括
在接受PCI的ST升高心肌梗塞 (STEMI) 患者中,QRS复合体 (fQRS) 的碎片化与C反应蛋白 (CRP) 水平升高有关. 这表明fQRS在心肌缺血期间可能表明显著的炎症.
科学领域:
- 心脏病学 心脏病学
- 生物医学工程 生物医学工程
- 临床研究 临床研究
背景情况:
- 在全球范围内,ST升高心肌梗塞 (STEMI) 仍然是心血管死亡的主要原因.
- 早期风险分层对于有效的STEMI管理至关重要,特别是在资源有限的环境中.
- QRS碎片化 (fQRS) 是一种新兴的心电学标志物,在STEMI中具有预后影响.
研究的目的:
- 调查与STEMI患者进行初级皮肤冠状动脉干预 (pPCI) 的fQRS发生相关的潜在机制和风险因素.
- 在pPCI后的STEMI患者中分析fQRS与各种临床和生化参数之间的相关性.
主要方法:
- 分析了2020年9月至2021年6月期间接受pPCI的122名STEMI患者的队列.
- 评估了fQRS发生情况,并与临床数据和生物化学标记相关联,包括C-反应蛋白 (CRP) 和淋巴膜过率 (GFR).
- 用单变量和多变量逻辑回归模型来确定fQRS的独立预测因子.
主要成果:
- 在研究的STEMI患者中,fQRS模式在33.6%的患者中被观察到.
- 无变量分析显示fQRS与GFR (p=0.050) 和CRP水平 (p=0.014) 之间存在显著的关联.
- 多变量分析证实,在入院时,只有较高的CRP水平独立地与fQRS的存在相关 (OR=3.44,p=0.029).
结论:
- 在接受pPCI治疗的STEMI患者中,fQRS和CRP水平之间存在显著的相关性.
- 在心肌缺血的情况下,fQRS可以作为广泛炎症的有价值指标.
- 进一步的研究可以探索fQRS在风险分层和指导STEMI治疗干预中的作用.

01:30Acute Coronary Syndrome I: Introduction
744
Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...

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...

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...

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...

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...
