Cardiovascular Mortality Prediction in Maintenance Hemodialysis Patients

This prospective, single-center observational cohort study evaluates cardiovascular mortality risk in adults receiving maintenance hemodialysis. During the first year after enrollment, four scheduled assessments are used to characterize demographic factors, dialysis treatment, medication use, routine laboratory measures, and the proportion of serum phosphate measurements within the protocol-defined target range. Participants are subsequently followed for cardiovascular mortality. The study evaluates factors associated with serum phosphate target achievement and develops a cardiovascular mortality prediction model in the overall cohort, with a prespecified subgroup analysis among participants who undergo parathyroidectomy. No treatment or procedure is assigned by the study investigators.
