Abstract

Few studies have investigated the incidence of cardiovascular disease (CVD) in the Asian chronic kidney disease (CKD) population. This study assessed the incidence of CVD, death, and a composite outcome of CVD and death in a prospective Korean predialysis CKD cohort. From a total of 2179 patients, incidence rates were analyzed, and competing risk analyses were conducted according to CKD stage. Additionally, incidence was compared to the general population. During a median 4.1 years of follow-up, the incidence of CVD, all-cause death, and the composite outcome was 17.2, 9.6, and 24.5 per 1000 person-years, respectively. These values were higher in diabetic vs. non-diabetic subjects (P < 0.001). For all outcomes, incidence rates increased with increasing CKD stage (CVD, P = 0.001; death, P < 0.001; and composite, P < 0.001). Additionally, CKD stage G4 [hazard ratio (HR) 2.8, P = 0.008] and G5 (HR 5.0, P < 0.001) were significant risk factors for the composite outcome compared to stage G1 after adjustment. Compared to the general population, the total cohort population (stages G1-G5) showed significantly higher risk of CVD (HR 2.4, P < 0.001) and the composite outcome (HR 1.7, P < 0.001). The results clearly demonstrate that CKD is a risk factor for CVD in an Asian population.
