Chronic renal insufficiency leads to many cardiovascular complications and provide worst prognosis, especially when patients need hemodialysis. The atherosclerosis of chronic hemodialysis patients is qualified as "accelerated" by some authors, because of a very fast and large progression. To improve prognosis, it seems to be very important to detect and treat the frequent and serious underlying cardiovascular disease. Because of the high rate of diabetes mellitus, silent ischemia is a very frequent clinical situation. In the other hand, coronary artery disease in chronic hemodialysis patients is frequently complex, with a large coronary extension and high rate of coronary calcifications. Consequently, this disease needs a specific therapeutic approach. Even though, percutaneous coronary interventions (PCI) are more complex in this population, it provides good results, and improves patient's prognosis. However, the rate of complications of the vascular approach and the rate of restenosis is high. New devices, such as Drug Eluting Stents (DES) can critically decrease restenosis rate, and closure devices for trans-femoral approach, provides very encouraging results in this high risk population. Despite, good results of PCI with DES use, the mortality is still high in this population. To improve our efficiency, we have to progress in our therapeutic strategies and optimize medical approach to treat the important biological perturbations.
慢性肾功能不全导致许多心血管并发症,并带来最差的预后,尤其是当患者需要血液透析时。一些作者认为慢性血液透析患者的动脉粥样硬化属于“加速型”,因为其进展非常迅速且范围广泛。为改善预后,检测和治疗常见且严重的潜在心血管疾病似乎非常重要。由于糖尿病发生率高,无症状性缺血是一种非常常见的临床情况。另一方面,慢性血液透析患者的冠状动脉疾病通常较为复杂,冠状动脉病变范围广且冠状动脉钙化率高。因此,这种疾病需要特定的治疗方法。尽管经皮冠状动脉介入治疗(PCI)在这一人群中更为复杂,但它能取得良好效果并改善患者预后。然而,血管介入治疗的并发症发生率和再狭窄率较高。新型装置,如药物洗脱支架(DES)可显著降低再狭窄率,用于经股动脉途径的闭合装置在这一高风险人群中也取得了非常令人鼓舞的结果。尽管使用DES进行PCI取得了良好效果,但该人群的死亡率仍然很高。为提高我们的治疗效果,我们必须在治疗策略上取得进展,并优化医疗方法以治疗重要的生物学紊乱。
