A 10-year post-trial monitoring of patients with newly diagnosed type 2 diabetes randomised in the "United Kingdom Prospective Diabetes Study" (UKPDS) demonstrated a continued reduction in microvascular risk (-24%, p = 0.001) and emergent risk reductions for myocardial infarction (-15%, p = 0.01) and death from any cause (-13%, p = 0.007), despite an early loss of glycaemic differences ("legacy effect"). A continued benefit after metformin therapy was evident during the ten-year post-trial follow-up among overweight patients (-33%, p = 0.005 for myocardial infarction and -27%, p = 0.002 for death from any cause). In contrast, the benefits of previously improved blood pressure control were not sustained when between-groups differences in blood pressure were lost during follow-up, except for a reduced risk for peripheral vascular disease. These observations are strong arguments in favour of an early optimisation of blood glucose control and of a sustained control of blood pressure in patients with type 2 diabetes.
