概括
长期暴露于全身免疫炎症指数 (SII) 会增加心肌梗塞患者的主要不良心血管事件 (MACE) 的风险. 晚期SII升高显著增加MACE风险,强调需要在术后持续控制炎症.
科学领域:
- 心脏病学 心脏病学
- 免疫学 免疫学 免疫学
- 预测生物标志物 预测生物标志物
背景情况:
- 系统性免疫炎症指数 (SII) 是各种疾病中公认的预后标志物.
- 关于SII与心肌梗塞 (MI) 患者的长期结果之间的联系的证据有限.
- 经过皮肤冠状动脉干预 (PCI) 的急性ST升高心肌梗塞 (STEMI) 患者需要强大的预后工具.
研究的目的:
- 研究在PCI后的STEMI患者中,累积暴露于SII及其与主要心血管不良事件 (MACE) 的时间进程动态之间的关系.
- 评估SII对MACE在这个患者队列中的预测价值.
主要方法:
- 在1年的随访期间,研究了一组480名接受紧急冠状动脉血管造影的STEMI患者.
- 计时加权累计SII和高SII暴露的持续时间计算从住院到1年的随访.
- 根据时间加权累积SII和SII斜率对患者进行了分类,以分析MACE风险.
主要成果:
- 在对混因素进行调整后,较高的时间加权累积SII (高于中位数) 与MACE风险增加有关 (HR,1.090).
- 具有高时间加权累积SII和正SII斜率的患者显示MACE的风险明显更高 (HR,4.096).
- 晚期上升的SII,即使与相似的累积暴露,也与更高的MACE风险有关.
结论:
- 长期累积暴露于SII是PCI后STEMI患者MACE的显著预测因素.
- 升高SII水平的时间和持续时间,特别是晚期增加,是不良心血管事件的关键决定因素.
- 有效的晚期炎症控制对于改善STEMI患者的长期预后至关重要.

01:25Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...
01:30Acute Coronary Syndrome I: Introduction
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...

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...
