概括

术外心肌梗塞 (MI) 或PCI后的损伤是常见的. 在ALPHEUS试验中,更长的支架长度 (>60mm) 是唯一与心脏病发作或损伤相关的一致因素.

科学领域:

心脏病学心脏病学
干预心脏病学干预心脏病学
临床试验临床试验

背景情况:

周围手术性心肌梗塞 (MI) 或皮肤冠状动脉干预 (PCI) 后的损伤是常见的并发症.
这些事件与不良的长期缺血性结果和增加的死亡率有关.
了解导致周围手术性心脏病发作的因素对于改善患者管理至关重要.

研究的目的:

在接受选择性PCI的患者中描述与周围手术性MI相关的因素.
通过使用多个既定的定义来分析周围手术性心肌亡.
在慢性冠状动脉综合征的背景下,确定心脏病发作或心肌损伤的预测因素.

主要方法:

在ALPHEUS-MI研究中对1883名患有慢性冠状动脉综合征的患者进行了选择性PCI的分析.
使用四个不同的终点定义,包括ARC类型4a/4b MI和心肌损伤,对周围手术心肌亡的评估.
多变量分析以确定心脏病发作或心肌损伤的独立相关物.

主要成果:

在ALPHEUS试验中,主要和次要终点分别发生在35.9%和77.2%的患者身上.
周围手术性心脏病发作 (ARC2-SCAI) 发生在2.0%的患者中,显著的心肌损伤 (ARC2) 在3.2%的患者中.
在所有定义中,增长的支架长度 (>60mm) 是所有定义中MI或心肌损伤的唯一一致的相关因子 (调整的OR2.2-6.0).

结论:

高风险特征的积累,包括患者特征,病变复杂性和程序复杂性,增加了围绕程序性MI/损伤的风险.
广泛的动脉样硬化,需要更长的冠状动脉支架,是周围手术性心脏病/损伤的重要贡献者.
研究结果强调了支架长度的重要性,作为预防周围手术并发症的可修改因素.

关键词:

慢性冠状动脉综合征慢性冠状动脉综合征选修的PCI是可以选择的.心肌梗塞的心脏病发作心肌损伤是指心肌损伤.

Cardiac Catheterization I: Pre-Procedure Overview

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

Acute Coronary Syndrome IV: Interprofessional Care

IntroductionThe management of Acute Coronary Syndrome (ACS) aims to minimize myocardial damage, preserve myocardial function, and prevent complications.Initial ManagementInpatient management involves continuous cardiac monitoring, preferably in an ICU, focusing on blood pressure, serum sodium, potassium, and creatinine levels, and urine output. Ongoing pharmacologic management is crucial for stabilizing the patient.Supplemental Oxygen: Administer supplemental oxygen if oxygen saturation is...

Acute Coronary Syndrome I: Introduction

Acute 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...
