Hypertensive-type target organ damage is increased in patients with diabetes mellitus compared with blood pressure–matched individuals with euglycemia.18 Hyperglycemia and accompanying metabolic abnormalities partly explain this gap.9 Another possible explanation is a lower sensitivity of clinic blood pressure measurements in diabetic patients.10,11 Failure of clinic measurements to detect out-of-office elevated blood pressure results in the recently characterized entity of “masked hypertension,” also known as isolated ambulatory hypertension and reverse white-coat hypertension, in which “true” blood pressure is underestimated and thus undertreated (among subjects with treated hypertension, these terms refer to masked uncontrolled hypertension12). The prognostic consequences of masked hypertension are similar to those of sustained hypertension.13,14 Several studies have documented a higher level of target organ damage among subjects with treated hypertension and “masked” blood pressure elevation, namely, misleadingly controlled clinic blood pressure.1518
