The purpose of this study was to evaluate the relationship between remnant cholesterol (RC) to high-density lipoprotein cholesterol (HDL-C) ratio and the risk of coronary artery disease (CAD). We also investigated the clinical value of RC/HDL-C ratio in evaluating the severity of CAD and in predicting the short-term prognosis of CAD patients.
In total, 615 patients were enrolled and they were classified into a CAD group (418 cases) and a normal group (197 cases) according to the results of coronary angiography. Serum RC/HDL-C ratio and Gensini score were calculated. Multivariate logistic regression and receiver operating characteristic (ROC) curves were employed to evaluate the association between RC/HDL-C ratio and CAD. The effect of RC/HDL-C ratio on the progression of major adverse cardiovascular events (MACEs) was also explored.
Increased RC/HDL-C ratio was associated with an increased risk of CAD (OR: 11.122; 95% CI: 5.903-20.954; P < 0.001). When stratified by CAD subtypes, increased RC/HDL-C ratio was correlated with a greater risk of acute coronary syndrome (ACS) (OR:1.549; 95% CI: 1.014-2.364; P < 0.05). Compared with the first quartile, the 4th quartile of RC/HDL-C ratio had a 9.774-fold ( P = 0.000) increase in the odds ratio for CAD, and a 2.241-fold ( P = 0.017) increase in the odds ratio for ACS. RC/HDL-C ratio was an independent determinant of Gensini score ≥32 (OR: 2.138, 95% CI:1.389-3.292, P < 0.01), and multi-branch (MVD) (OR: 2.245; 95% CI: 1.468-3.443; P < 0.001). The prevalence of Gensini score ≥32 and MVD in the 4th quartile of RC/HDL-C ratio group were much higher than that of other quartile groups ( P < 0.01). Moreover, the areas under the ROC for the predictive value of RC/HDL-C ratio for CAD, ACS, Gensini score ≥32, and MVD were 0.702, 0.563, 0.602, and 0.669, respectively. Furthermore, the incidence of MACEs was significantly increased in CAD patients with levels of RC/HDL-C ratio ( P < 0.05).
RC/HDL-C ratio plays an important role in the progression and severity of CAD.
本研究旨在评估残余胆固醇（RC）与高密度脂蛋白胆固醇（HDL-C）比值与冠心病（CAD）风险之间的关系。我们还研究了 RC/HDL-C 比值在评估 CAD 严重程度和预测 CAD 患者短期预后方面的临床价值。
共纳入 615 例患者，根据冠状动脉造影结果分为 CAD 组（418 例）和正常组（197 例）。计算血清 RC/HDL-C 比值和 Gensini 评分。采用多变量逻辑回归和受试者工作特征（ROC）曲线评估 RC/HDL-C 比值与 CAD 的关系。还探讨了 RC/HDL-C 比值对主要不良心血管事件（MACE）进展的影响。
RC/HDL-C 比值升高与 CAD 风险增加相关（OR：11.122；95%CI：5.903-20.954；P<0.001）。按 CAD 亚型分层，RC/HDL-C 比值升高与急性冠脉综合征（ACS）风险增加相关（OR：1.549；95%CI：1.014-2.364；P<0.05）。与第 1 四分位相比，RC/HDL-C 比值第 4 四分位 CAD 的比值比（OR）增加了 9.774 倍（P=0.000），ACS 的比值比增加了 2.241 倍（P=0.017）。RC/HDL-C 比值是 Gensini 评分≥32（OR：2.138，95%CI：1.389-3.292，P<0.01）和多支病变（MVD）（OR：2.245；95%CI：1.468-3.443；P<0.001）的独立决定因素。RC/HDL-C 比值第 4 四分位组 Gensini 评分≥32 和 MVD 的患病率明显高于其他四分位组（P<0.01）。此外，RC/HDL-C 比值对 CAD、ACS、Gensini 评分≥32 和 MVD 的预测价值的 ROC 曲线下面积分别为 0.702、0.563、0.602 和 0.669。此外，CAD 患者的 RC/HDL-C 比值水平显著增加了 MACE 的发生率（P<0.05）。
RC/HDL-C 比值在 CAD 的进展和严重程度中起重要作用。
