The association between single measurements of carotid‐femoral pulse wave velocity (cf PWV ) and cardiovascular ( CV ) events is driven by late events beyond 12 months of follow‐up. This prospective study compares single measurements of cf PWV vs the 2‐year delta cf PWV and the association with short‐term development of CV events in hemodialysis patients. cf PWV was performed at t =0 and t =1 two years later, and patients were followed‐up for development of CV events through 12 months (n=66). In Cox regression models adjusted for CV risk factors, history of CV events and delta cf PWV remained associated with the development of CV events (hazard ratio for prior CV events=8.9, P =.03; hazard ratio for delta cf PWV =1.14; P =.002). When delta cf PWV was substituted for single cf PWV measurement, none of the single measures were associated with new CV events. The change in cf PWV , but not single measurements of cf PWV , was associated with the development of CV events through 12 months.
