Peripheral vascular disease (PVD) is very prevalent in the United States and is part of a global vascular problem. PVD patients have a heightened inflammatory state and are at high risk of death from acute cardiovascular problems rather than from progression of PVD. Modifiable risk factors for PVD include smoking, hypertension, diabetes, hyperlipidemia, elevated high sensitivity C-reactive protein, obesity, and the metabolic syndrome. Symptomatic treatment of claudication includes smoking cessation, exercise, cilostazol, statins, and revascularization with percutaneous or surgical therapy. Antithrombotic therapy with aspirin or clopidogrel is important to reduce cardiovascular events but does not affect symptoms of claudication. Patients with rest limb ischemia or ulceration should be revascularized to minimize the chance of limb loss. Percutaneous revascularization is not without significant complications, however, and future research needs to focus on inflammation, thrombosis, and restenosis in the PVD patient. Finally, new devices that tackle difficult lesions, drug-eluting stents, and pharmacologic agents that reduce global atherosclerosis are on the horizon and are likely to become critical components in the management of the PVD patient.
外周血管疾病(PVD)在美国非常普遍,是全球血管问题的一部分。PVD患者处于炎症状态加剧的情况,死于急性心血管问题的风险很高,而非死于PVD的进展。PVD的可改变风险因素包括吸烟、高血压、糖尿病、高脂血症、高敏C反应蛋白升高、肥胖和代谢综合征。间歇性跛行的对症治疗包括戒烟、运动、西洛他唑、他汀类药物,以及采用经皮或手术治疗进行血运重建。使用阿司匹林或氯吡格雷进行抗栓治疗对于减少心血管事件很重要,但不影响间歇性跛行的症状。患有静息肢体缺血或溃疡的患者应进行血运重建,以尽量减少肢体丧失的几率。然而,经皮血运重建并非没有重大并发症,未来的研究需要关注PVD患者的炎症、血栓形成和再狭窄。最后,能够处理复杂病变的新设备、药物洗脱支架以及减少整体动脉粥样硬化的药物即将出现,并且可能成为PVD患者管理中的关键组成部分。
