摘　　要：目的:探讨强化降脂策略对多支血管病变急性冠状动脉综合征(ACS)患者短期预后的影响。方法:回顾性纳入2019年8月至2020年11月期间在武汉大学中南医院心内科接受冠状动脉支架置入术的多支血管病变ACS患者136例,将其分为强化降脂组[3个月内将低密度脂蛋白胆固醇(LDL-C)控制<1.0mmol/L,且12个月内持续达标,n=69]和标准降脂组(12个月内将LDL-C逐渐控制<1.4 mmol/L,n=67)。观察两组患者出院后12个月内总胆固醇(TC)、甘油三酯(TG)、LDL-C、高密度脂蛋白胆固醇(HDL-C)、脂蛋白(a)[Lp(a)]水平的变化趋势,比较两组患者出院12个月时的主要不良心血管事件(MACE,包括心原性死亡、心肌梗死、靶血管血运重建和脑卒中)发生情况。结果:强化降脂组与标准降脂组患者入院时的基线资料相似,基线TC、TG、LDL-C、HDL-C水平差异均无统计学意义(P均>0.05)。出院3个月时,与入院时相比,强化降脂组患者的TC、TG、LDL-C、Lp(a)水平均明显降低(P均<0.05),HDL-C水平无明显变化(P>0.05);标准降脂组患者的TC、LDL-C水平均明显降低(P均<0.05),TG、HDL-C和Lp(a)水平均无明显变化(P均>0.05)。出院3、6、12个月时,强化降脂组患者的TC、LDL-C水平均明显低于标准降脂组(P均<0.01)。Kaplan-Meier生存曲线显示,出院12个月时,强化降脂组的MACE发生率明显低于标准降脂组(2.90%vs.14.93%,χ2=6.090,P=0.014)。多因素Cox回归分析显示,与标准降脂策略相比,强化降脂策略可显著降低多支血管病变ACS患者出院12个月时的MACE发生风险(HR=0.177,95%CI:0.037~0.838,P=0.029)。结论:在多支血管病变ACS患者中,与标准降脂策略相比,强化降脂策略很可能会降低短期MACE发生风险,未来需要开展大规模的前瞻性多中心研究来进一步验证。Objectives:To explore the impact of intensive lipid-lowering strategy on short-term prognosis of acute coronary syndrome(ACS)patients with multi-vessel disease.Methods:A total of 136 ACS patients with multi-vessel disease who received coronary stenting at Zhongnan Hospital of Wuhan University from August 2019 to November 2020 were enrolled in this study.Patients were divided into intensive lipidlowering group(control low density lipoprotein cholesterol[LDL-C]below 1.0 mmol/L within 3 months,and continuously meet the standards within 12 months,n=69)or standard lipid-lowering group(gradually control LDL-C below 1.4 mmol/L within one year,n=67).The total cholesterol(TC),triglycerides(TG),LDL-C,high-density lipoprotein cholesterol(HDL-C),and lipoprotein(a)(Lp[a])data were collected.Incidence of major adverse cardiovascular events(MACE,including cardiac death,myocardial infarction,target vessel revascularization and stroke)were observed during 12 months of follow up.Results:The baseline data of the intensive lipid-lowering group and the standard lipid-lowering group were consistent before intervention.At the timeline of enrollment,there was no statistically significant difference in the blood lipid profiles(including TC,TG,LDL-C,HDL-C)between the two groups.After 3-months,patients in the intensive lipid-lowering group experienced significantly lower TC,TG,LDL-C and Lp(a)compared with baseline values(all P<0.05),while HDL-C remained unchanged(P>0.05).The standard lipid-lowering group showed a significant decrease in TC and LDL-C compared with baseline values(both P<0.05).The TC and LDL-C levels were significantly lower in the intensive lipid-lowering group than in the standard lipid-lowering group at 3/6/12 months follow up after discharge(all P<0.01).At 12 months follow-up,Kaplan-Meier survival analysis showed that the incidence of MACE was significantly lower in the intensive lipid-lowering group than in the standard lipid-lowering group(2.90%vs.14.93%,χ2=6.090,P=0.014).Multiple Cox regression analysis revealed that
