Abstract

|
|
Purpose : The prevalence of Chronic Kidney Disease (CKD) is increasing worldwide and was recently reported to be up to 13.7% in general population in Korea. The purpose of this study was to investigate the prevalence of CKD in subjects undergoing coronary angiography (CAG).
Methods : Six hundred six subjects who underwent CAG in Korea University Anam Hospital during the time frame of 4 months were included and prevalence of CKD was estimated by using K/DOQI guideline with MDRD equation. coronary artery disease was defined as one or more significant stenosis (50% or more) at CAG.
Results : The prevalence of CKD was 36.4%. The proportion of hypertension and diabetes, the wellknown risk factors of CKD were not different with general population. The prevalence of coronary artery disease was not different between two groups with or without CKD.
Conclusion : The prevalence of CKD in subjects who undergo CAG is higher than that in general population (36.4% vs. 13.7%). It seems to be related with or other factors than hypertension and diabetes. Subsequently, using contrast media to this population might carry a higher risk of developing contrast induced acute kidney injury. More attention to assessing kidney function before CAG in this population is needed.
