Atherosclerosis is accelerated in hemodialysis patients. Intima media thickness (IMT) is a strong predictor for cardiovascular events in the general population. Using B-mode ultrasonography, IMT in the common carotid arteries was measured in 99 nondiabetic hemodialysis patients (44 women and 55 men, mean age 53.1 years and mean dialysis duration 45.8 months). During a follow-up of 42.4 +/- 19.5 months, 33 patients died, 19 (57.6%) of them of cardiovascular causes. In these 19 patients IMT was significantly higher (0.89 vs. 0.69 mm) than in those who survived. Correlation between cardiovascular mortality and IMT was found. Patients were divided in relationship to the tertiles of IMT and the risk for cardiovascular death was progressively higher from the first tertile of IMT onward (P < 0.0006). IMT turned out to be an independent predictor of cardiovascular death (P < 0.025). According to our results IMT may be usefully applied for cardiovascular mortality risk stratification in nondiabetic hemodialysis patients.
血液透析患者的动脉粥样硬化进程加快。在普通人群中,内膜中层厚度(IMT)是心血管事件的有力预测指标。使用B型超声,对99例非糖尿病血液透析患者(44名女性和55名男性,平均年龄53.1岁,平均透析时间45.8个月)的颈总动脉IMT进行了测量。在42.4±19.5个月的随访期间,33例患者死亡,其中19例(57.6%)死于心血管疾病。这19例患者的IMT(0.89 vs. 0.69 mm)显著高于存活患者。发现心血管死亡率与IMT之间存在相关性。根据IMT三分位数对患者进行分组,从IMT的第一个三分位数起,心血管死亡风险逐渐升高(P < 0.0006)。结果表明IMT是心血管死亡的独立预测指标(P < 0.025)。根据我们的研究结果,IMT可有效用于非糖尿病血液透析患者心血管死亡风险的分层。
