概括

左主冠状动脉疾病 (LMCAD) 两叉病变增加了主要心脏不良事件 (MACE) 的风险,特别是重复血管化,无论非LM SYNTAX得分如何. 损伤的复杂性是关键.

科学领域:

干预心脏病学干预心脏病学
心血管医学心血管医学
临床结果研究研究

背景情况:

左主冠状动脉疾病 (LMCAD) 的复杂性通常使用SYNTAX评分进行评估.
高的SYNTAX得分可以表明复杂的左主病变或多血管疾病.
对这些不同患者群体的预后数据有限.

研究的目的:

评估皮肤冠状动脉干预 (PCI) 在未受保护的LMCAD患者的临床结果.
根据LM病变位置 (身体/骨架与分叉) 和非LM SYNTAX评分来比较结果.
为了确定病变复杂度与疾病负担对患者预后的影响.

主要方法:

为未受保护的LMCAD进行PCI的患者被分为四组.
根据LM病变位置 (身体/骨架与分叉) 和非LM SYNTAX评分 (≤8与>8) 定义了组.
主要终点是1年的重大心脏不良事件 (MACE),包括死亡,心肌梗塞或目标血管再血管化 (TVR).

主要成果:

在869名患者中,69.2%的患者患有LM分叉病变,44.8%的患者具有非LM SYNTAX评分>8.8.
具有高非LM分数的患者表现出更高的并发病率.
经过调整后,LM分叉病变与1年的MACE增加有关,主要是由TVR驱动的.
在高非LM得分的身体/骨病变和参考组之间没有观察到MACE的显著差异.

结论:

在接受为LMCAD进行PCI的患者中,LM分支病变与重复血管化的可能性更高有关.
这种增加的TVR风险无论非LM SYNTAX得分如何,都会持续存在.
关节损伤本身的复杂性,特别是分叉的参与,是预测结果的关键因素,与整体疾病负担分开.

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...
