Background: Ambulatory BP monitoring (ABPM) might be more accurate than clinical BP measurement. It allows detection of nocturnal BP and dipping patterns, and can reduce false-positive results by detecting white-coat hypertension and false-negative results by detecting masked hypertension.
Objective: Assessing the use of ambulatory BP monitoring (ABPM) in individuals with diabetes mellitus to identify the presence of hypertension and its association with arterial stiffness.
Patients and Methods: The study included 100 diabetic patients in addition to 20 apparently healthy individuals.
Results: In comparison with healthy subjects, patients with diabetes were found to have hypertension using ABPM. ABPM appeared to be useful in the detection of hypertension in patients with diabetes. Comparison between patients and control showed statistically significant difference according to average day, average night and allover average readings. Arterial stiffness also found to be increased in patients with hypertension with statistically significant difference between studied groups according to stiffness index.
Conclusion: ABPM analysis revealed that about one-third of the participants with diabetes had masked hypertension. Those individuals cannot be detected by office BP alone. Moreover, arterial stiffness increased in individuals with masked hypertension. These findings supported the use of ABPM to identify individuals at risk of cardiovascular disease.
