肢体闭塞性动脉硬化是临床常见的外周动脉疾病,常造成患者截肢,甚则危及生命。目前越来越多的证据表明同型半胱氨酸(Hcy)水平升高已成为新的动脉粥样硬化的独立危险因素。本研究采用病例对照的方法对肢体闭塞性动脉硬化患者血清同型半胱氨酸水平、临床病情严重程度及相关因素进行初步探讨。现将结果分析报告如下: Limb occlusive arteriosclerosis is a common clinical peripheral arterial disease, often resulting in amputation of patients, and even life-threatening. There is growing evidence that elevated homocysteine ​​(Hcy) has become an independent new risk factor for atherosclerosis. In this study, the case-control method of serum levels of homocysteine ​​in patients with arteriosclerosis obliterans, the severity of clinical conditions and related factors were initially explored. The results of the analysis report is as follows:
