Patients with peripheral arterial disease (PAD) are at very high risk of cardiovascular events, but risk factor management is usually suboptimal. This Joint Task Force from the European Atherosclerosis Society and the European Society of Vascular Medicine has updated evidence on the management on dyslipidaemia and thrombotic factors in patients with PAD. Guidelines recommend a low-density lipoprotein cholesterol (LDLC) goal of more than 50% reduction from baseline and <1.4 mmol/L (<55 mg/dL) in PAD patients. As demonstrated by randomized controlled trials, lowering LDL-C not only reduces cardiovascular events but also major adverse limb events (MALE), including amputations, of the order of 25%. Addition of ezetimibe or a PCSK9 inhibitor further decreases the risk of cardiovascular events, and PCSK9 inhibition has also been associated with reduction in the risk of MALE by up to 40%. Furthermore, statin-based treatment improved walking performance, including maximum walking distance, and pain-free walking distance and duration. This Task Force recommends strategies for managing statin-associated muscle symptoms to ensure that PAD patients benefit from lipid-lowering therapy. Antiplatelet therapy, either daily clopidogrel 75 mg or the combination of aspirin 100 mg and rivaroxaban (2 × 2.5 mg) is also indicated to prevent cardiovascular events. Dual antiplatelet therapy (aspirin and rivaroxaban) may be considered following revascularization, taking into account bleeding risk. This Joint Task Force believes that adherence with these recommendations for lipid-lowering and antithrombotic therapy will improve the morbidity and mortality in patients with PAD.
患有外周动脉疾病 (PAD) 的患者发生心血管事件的风险非常高,但危险因素管理通常并不理想。 欧洲动脉粥样硬化学会和欧洲血管医学学会的联合工作组更新了 PAD 患者血脂异常和血栓形成因素管理的证据。指南建议 PAD 患者的低密度脂蛋白胆固醇 (LDLC) 目标为从基线降低超过 50%,且<1.4 mmol/L(<55 mg/dL)。随机对照试验表明,降低 LDL-C 不仅可减少心血管事件,还可减少主要不良肢体事件 (MALE),包括截肢,幅度约为 25%。添加依折麦布或 PCSK9 抑制剂可进一步降低心血管事件的风险,PCSK9 抑制也与 MALE 风险降低多达 40%相关。此外,他汀类药物治疗改善了步行表现,包括最大步行距离、无痛步行距离和时间。该工作组建议管理他汀类药物相关肌肉症状的策略,以确保 PAD 患者受益于降脂治疗。抗血小板治疗,每日氯吡格雷 75 mg 或阿司匹林 100 mg 和利伐沙班(2×2.5 mg)联合应用,也可用于预防心血管事件。考虑到出血风险,可考虑在血运重建后进行双联抗血小板治疗(阿司匹林和利伐沙班)。该联合工作组认为,坚持这些降脂和抗血栓治疗建议将改善 PAD 患者的发病率和死亡率。
