Relationship between diurnal blood pressure variation and diurnal blood glucose levels in type 2 diabetic patients.

Background: Hypertension and hyperglycemia are established risk factors for progression of microangiopathies and macroangiopathies in type 2 diabetes mellitus. Cardiovascular risk is even more increased in diabetic patients with nocturnal nondipping or postprandial hyperglycemia. We therefore investigated the relationship between diurnal hyperglycemia and diurnal blood pressure (BP) variation in patients.
