BACKGROUND AND OBJECTIVES: In the general population, the presence of cerebral microbleeds on T2*-weighted magnetic resonance imaging has been reported to be a predictor of future stroke. Patients with CKD have a high prevalence of microbleeds and are at higher risk of ESRD as well as cardiovascular disease, including stroke. Because endothelial dysfunction is the common pathophysiology among microbleeds, CKD, and cardiovascular disease, we hypothesized that the presence of microbleeds would be an important predictor of composite outcome, including both cardiovascular disease and renal events, in those with CKD. DESIGN, SETTINGS, PARTICIPANTS, 95% confidence interval 95% CI, 1.68 to 3.46 for composite outcome; hazard ratio, 2.41; 95% CI, 1.55 to 3.77 for renal outcome; hazard ratio, 3.46; 95% CI, 1.62 to 7.43 for cardiovascular disease outcome). CONCLUSIONS: In patients with CKD, the presence of microbleeds is a novel and independent predictor of both renal and cardiovascular disease end points.
