ABSTRACT
Objective To investigate the prevalence of CKD in patients underging coronary angiography with suspected coronary heart disease(CHD). Methods A total of 1031patients with suspected CHD undergoing coronary angiography in Zhongda Hospital from December 2008 to October 2009 were enrolled in the study.The prevalence of CKD and associated risk factors were analyzed.GFR Wag estimated with MDRD equation.CKD was deftned as eGFR<60branches of coronary artery was considered as CHD. Results The mean age of patients were (64.37±11.02)years.There were 543 males and 488 females,including 551 patients with CHD and 134 patients with CKD(13%).Patients with CHD had a significantly higher prevalence of CKD compared with patients without CHD(18.33%vs 6.88%,P<0.01).With the increasing number of stenosis coronary vessels(n=0,1,2,3),eGFR was declined[(84.25±19.00),(81.61±23.92),increased(0.42%,0.82%,1.96%,3.25%,P=0.006),and the prevalence of CKD increased (6.88%,13.11%,21.57%,23.38%,P<0.01).Logistic regression analysis indicated that increasing age(OR 1.094,95%C/1.068 to 1.120),increasing number of stenosis coronary vessels(OR 1.288,95%CI 1.074 to 1.543).hypertension(OR 1.974,95%CI 1.082 to 3.603),cardiac systolic insufficiency(OR 3.183,95%CI 1.696 to 5.972),and hyperuricemia(OR 5.366,95%CI 3.224 to 8.9311 were risk factors for CKD. Conclusions The prevalence of CKD in patients with CHD diagnosed by coronary angiography is quite high.Aging,elevated number of stenosis coronary vessels,hypertension,cardiac systolic insufficiency and hyperuricemia are important risk factors for angiographic patients with CKD.
ABSTRACT
0.05).3.The more cardiovascular risk factors,the more serious coronary artery disease.Conclusion:Besides BMI,conventional risk factors of cardiovascular contribute to coronary heart disease in this area,and they play an important and independent role in occurrence and progression of coronary artery disease.
