effect. Until now its relation to the extent and severity of the atheromatic lesions had not been established by standard procedures. HYPOTHESIS This study examined the correlation of Lp(a) to the extent and severity of coronary artery disease (CAD) and its relation to unstable clinical events (not including sudden death). METHODS In 202 patients undergoing coronary angiography, plasma lipids were measured
背景技术Lp(a)是具有促血栓形成作用的高度动脉粥样化的颗粒。到目前为止,还没有通过标准程序确定其与动脉粥样硬化病变程度和严重程度的关系。假设这项研究检查了Lp(a)与冠状动脉疾病(CAD)的程度和严重程度的相关性及其与不稳定的临床事件(不包括猝死)的关系。方法在202例接受冠状动脉造影的患者中,采用常规程序测定血脂,采用酶联免疫吸附测定法测定Lp(a)。CAD的程度用患病血管的数量及其严重程度来表示,取决于严重程度系数和阻塞系数。结果LP(a)与患病血管数量(p = 0.0007)之间存在非常密切的关系,表明弥漫性动脉粥样硬化,但与病变的严重程度无关。被找到。但是,它是唯一与完全阻塞的血管数量显着相关的脂质(p = 0.0003)。Lp(a)的血栓形成能力表现为Lp(a)升高的患者心肌梗死发生率增加和不稳定的心绞痛发作(p = 0.0157)。结论Lp(a)升高易导致CAD和总闭塞程度,
