AIM
The link of oxidized-low-density lipoprotein (ox-LDL) with premature coronary artery disease (CAD) has previously been less examined. Materials & methods: A total of 1217 patients with angiography-proven CAD were consecutively enrolled and divided into very-early CAD (VECAD), early CAD and late CAD subgroups. And 72 normal control of VECAD were examined. All the subjects were followed-up for an average of 31 months.
RESULTS
Patients with VECAD had higher ox-LDL levels; and logistic regression analysis indicated that ox-LDL was an independent risk factor for VECAD among patients with CAD (adjusted odds ratio: 1.024; p < 0.001). The Kaplan-Meier analysis revealed that VECAD patients had lower event-free survival (p < 0.01, respectively).
CONCLUSION
Elevated plasma ox-LDL level is independently associated with the presence and cardiovascular events in VECAD patients, suggesting that ox-LDL may be a prognostic predictor for VECAD.
目的
氧化型低密度脂蛋白（ox-LDL）与早发性冠状动脉疾病（CAD）之间的联系此前较少受到研究。材料与方法：连续纳入1217例经血管造影证实患有CAD的患者，并将其分为极早期CAD（VECAD）、早期CAD和晚期CAD亚组。同时检查了72例VECAD的正常对照者。所有受试者平均随访31个月。
结果
VECAD患者的ox-LDL水平较高；逻辑回归分析表明，ox-LDL是CAD患者中VECAD的独立危险因素（调整后的优势比：1.024；p<0.001）。Kaplan-Meier分析显示，VECAD患者的无事件生存率较低（p<0.01）。
结论
血浆ox-LDL水平升高与VECAD患者的患病情况及心血管事件独立相关，提示ox-LDL可能是VECAD的预后预测指标。
