概括

现有的风险评分对于具有高风险的穿皮冠状动脉干预 (HRPCI) 与穿皮左心室辅助装置 (pLVAD) 是不够的. 一个新的HRPCI得分表明,在这个复杂的患者群体中,医院内死亡率的预测得到了改善.

科学领域:

心脏病学心脏病学
干预心脏病学干预心脏病学
医疗器械技术医疗器械技术

背景情况:

通过皮肤使用左心室辅助器件 (pLVAD) 的高风险穿皮冠状动脉干预 (HRPCI) 越来越普遍.
现有的PCI风险评分并没有为pLVAD辅助HRPCI患者的独特复杂性开发.

研究的目的:

评估pLVAD辅助HRPCI患者当前PCI风险评分的表现.
开发一种新的,特定的风险评分,用于预测该患者群体的结果.

主要方法:

分析了PROTECT III多中心研究中的1237名接受pLVAD辅助HRPCI的患者.
计算和评估国家心血管数据注册表 (NCDR) 的病床和复杂高风险指示PCI (CHIP-PCI) 风险得分.
开发一种新的住院死亡风险评分,使用显著的手术前变量.

主要成果:

现有的NCDR和CHIP-PCI得分在预测住院事件方面显示出有限的准确性 (C指数分别为0.71和0.61).
确定了五个关键预测因素:年龄>80,EGFR<30,左主疾病,急性心肌梗塞,LVEF<30%.
新的HRPCI风险评分达到0.75的C指数,与30天死亡率有显著的相关性.

结论:

目前的PCI风险分层工具对于接受pLVAD辅助HRPCI的患者来说是不够的.
一个新的,易于计算的HRPCI风险评分显示了改善这种高风险组的临床决策的希望.

关键词:

在CHIP风险评分中,CHIP风险得分是:在HRPCI风险分数中,HRPCI风险分数是什么?高风险的穿皮冠状动脉干预.在医院死亡率.在 NCDR 风险评分中,NCDR 风险评分是:

Acute Coronary Syndrome III: Diagnostic Studies

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...

Imaging 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...
