Abstract

Objective: To determine the frequency of masked hypertension in normotensive
type2 diabetic patients by means of ambulatory blood pressure monitoring.
Methodology: A cross-sectional study was conducted in 230 normotensive
patients with type 2 diabetes mellitus. Patients underwent 24 hour ambulatory
blood pressure monitoring (ABPM). Patients with increased daytime blood
pressure levels (􀀂135/85mmHg) were classified as having masked
hypertension.
Results: The prevalence of masked hypertension was 31.7% (n=73). Normotensive
and masked hypertensive subjects, based on ambulatory blood
pressure, were not different in terms of age and diabetes duration. The office
systolic blood pressure was higher in those with masked hypertension than in the
normotensive group(128.8±8.5 vs. 123.9±9.2mmHg, p= 0.003).
Conclusion: Upto one third of normotensive type 2 diabetic patients have masked
hypertension according to ABPM. Therefore, ABPM is important to identify this
high-risk group so as to be able to take interventional measures early on.
