Resting heart rate (RHR) is a predictor of cardiovascular and renal events in patients with type 2 diabetes, according to a new single-centre, prospective study of 1,088 patients with type 2 diabetes. In patients with a history of cardiovascular disease, researchers found an association between high RHR and an increased incidence of the composite primary outcome of fatal and nonfatal renal and cardiovascular events and an association between high RHR and an increased incidence of the secondary outcome of nonfatal renal events.
