概括
术前P2Y12测定结果预测心脏手术患者的术后出血风险. 一个较低的P2Y12反应单元 (PRU) 切点更准确地识别出需要输血的人.
科学领域:
- 心脏病学 心脏病学
- 心胸外科手术 心胸外科手术
- 药理学 药理学是指药理学的学科.
背景情况:
- 在心脏手术中使用P2Y12抑制剂后,管理出血和缺血风险是具有挑战性的.
- 在手术前,正在探索P2Y12检测的使用,以优化手术时间.
研究的目的:
- 确定手术前P2Y12测定结果是否与输血需求,胸管输出和出血再手术相关.
- 为了确定一个P2Y12反应单元 (PRU) 切点来预测输血需求.
主要方法:
- 对729名心脏手术患者进行了术前P2Y12测定 (2012-2022) 的回顾性分析.
- 截止点分析以找到与>1个术后输血单位相关的PRU值.
- 根据风险调整的多变量回归以分析基于PRU分层的出血结果.
主要成果:
- 在729名患者中观察到173.0PRU的P2Y12水平中位数,主要是接受冠状动脉旁路移植的患者.
- 患有PRU<194的患者显示术后血红素值下降和胸管输出增加.
- 101名精确识别的患者的PRU切点需要≥1单位的包装红细胞 (PRBC) 输血 (OR 3.2,P < 0.001).
结论:
- 术前P2Y12测定对于估计心脏手术中术后出血风险非常有价值.
- 标准参考范围的切割点可能过于保守;较低的切割点 (例如,101 PRU) 更好地预测需要输血PRBC的需要.

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...

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...

Antiplatelet drugs emerge as frontline defenders against the insidious threat of thromboembolic diseases, where abnormal clots obstruct vital blood vessels. These drugs stand as bulwarks, inhibiting platelet aggregation and clot formation, thereby mitigating the risk of life-threatening conditions like myocardial infarction, coronary artery disease, and thrombotic strokes.

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...
