[摘要] 目的 分析冠状动脉钙化积分(CACS)与慢性肾脏病(CKD)相关临床指标的关系,探讨引起冠状动脉粥样钙化(CAC)的相关危险因素。 方法 选取2013年1月~2014年10月期间CKD患者257例,均行多层螺旋CT(MSCT)冠状动脉CACS扫描,分析其与CKD临床相关指标的关系。 结果 维持性血液透析(MHD)组CACS明显高于非维持性血液透析(NMHD)组,差异有统计学意义(P<0.01);CACS随着年龄的增加及肾功能下降而增加。CACS与年龄、BUN、SCr、P3-、Ca×P、TG、TC、PTH、Ferritin呈正相关(P<0.05),与GFR、HB呈负相关(P<0.05)。 结论 高龄及CKD患者发生CAC的危险性明显增加,CACS与CKD的严重程度相关。

[Abstract] Objective To analyze the relationship of coronary artery calcification score(CACS)and the related clinical indexes of chronic kidney disease(CKD),to evaluate the related risk factors of coronary artery calcification. Methods From January 2013 to October 2014,257 cases with CKD who were collected in the study were underwent multi-slice spiral CT(MSCT)scan for CACS,the relationship of CACS and the related clinical indexes of CKD were retrospectively analyzed. Results CACS in hemodialysis group was significantly higher than that in non-hemodialysis group, the difference was statistically significant(P<0.01), CACS increased with the growing age and decreasing renal function. There was a positive correlation comparing CACS with age,blood urea nitrogen,creatinine,serum phosphorus, calcium phosphorus product,three triglyceride,total cholesterol,parathyroid hormone,ferritin(P<0.05),and a negative correlation with glomerular filtration rate and hemoglobin(P<0.05). Conclusion The risk of coronary artery calcification in old people with CKD can significantly increase,the severity of CACS has been related to CKD.

近期研究显示[1-3],慢性肾脏病(chronic kidney disease,CKD)患者发生致死或非致死心血管事件的危险远远超过肾病进展的危险,CKD患者的主要死亡原因已转变为心血管疾病,尤其在透析患者中,其心血管事件发生的危险性是普通人群的10~20倍,及早发现CKD患者的心血管病变并进行早期治疗及干预对提高患者生活质量、降低病死率有重大意义。MSCT是目前定量检测CAC的最佳方法,CAC的程度可预测冠心病患者心血管事件的发生[4]。本研究通过对CKD患者MSCT检测CAC程度,计算CACS,分析CACS与CKD相关临床指标的关系,探讨引起CAC的相关危险因素,现报道如下。
1 资料与方法
1.1 临床资料
选取2013年1月~2014年10月期间CKD患者257例,男137例,女120例,年龄26~89岁,平均(64.3±15.3)岁。多次复查患者只取研究期间第1次检查结果。所有患者均符合2006年慢性肾脏病及透析临床指南(K/DOQI)中的诊断标准,肾小球滤过率(GFR)≤60 mL/(min·1.73 m2),排除严重感染及恶性肿瘤等。MHD患者GFR≤10 mL/(min·1.73 m2)。采用MDRD简化公式计算GFR。
1.2 检查方法
使用Philips Brilliance 16排螺旋CT机,扫描时患者屏气,心率控制在80次/min以下,在心动周期R-R间期获取平扫图像,所有图像经降噪去伪影处理,然后用于诊断分析。……
