Description
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 m2 was determined to be a critical cut-off level. Proteinuria, eGFR\60 ml/min/1.73 m2 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 m2 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
