Abstract:
BACKGROUND:Although a high prevalence of macrovascular disease (MVD) has been reported in patients with stage 3 chronic kidney disease (CKD), few studies have reported its risk with respect to the underlying cause of kidney disease. This study investigated the prevalence of MVD in type 2 diabetic patients with CKD stratified by CKD stage, as defined by estimated glomerular filtration rate (eGFR), as well as the risk factors for MVD. METHODS:1493 patients with diabetic CKD (1273 males, 220 females) were stratified by CKD stage (stage 1: 39, stage 2: 272, stage 3: 1052, stage 4: 101, stage 5: 29) based on eGFR calculated by the Japanese formula and averaged over 8 months. MVD was defined as one of the following: coronary heart disease (CHD), stroke or arteriosclerosis obliterans (ASO). RESULTS:The prevalence of MVD was 18.6%. A significant increasing trend in MVD prevalence was observed from stage 3 (17.78%) to 4 (52.48%). According to a receiver operating characteristic curve analysis on MVD prevalence in stage 3 patients, an eGFR of 46.4 ml/min/1.73 m(2) was determined to be a critical cut-off level. Proteinuria, eGFR <60 ml/min/1.73 m(2) and hyperuricemia were independent risk factors for MVD. CONCLUSIONS:In patients with diabetic CKD, a significant increase in MVD prevalence was observed from stage 3 to 4. An eGFR of 46.4 ml/min/1.73 m(2) is a critical level that affects MVD prevalence. From the perspective of cardiorenal association, CKD stage 3 should be divided into two substages. As hyperuricemia is related to an increased risk of MVD, uric acid control may be important in reducing MVD risk in diabetic CKD.
