Background and aimsThe parameters evaluated during 24-hour ambulatory blood pressure monitoring were reported to be predictors of cardiovascular events. We aimed to investigate mean blood pressure, blood pressure variability and pulse pressure during 24-hour ambulatory blood pressure monitoring in type 2 diabetes patients and to establish their relationship with the presence of atherosclerotic cardiovascular disease (CVD).MethodsThe observational study included type 2 diabetes patients randomly selected and distributed in 2 study groups depending on the presence of atherosclerotic cardiovascular disease: CVD(−), n=90, and CVD(+), n=87. Daytime, nighttime and 24-hour systolic and diastolic blood pressure were monitored and mean blood pressure, blood pressure variability and pulse pressure were calculated.ResultsThe study groups were comparable as age, gender ratio, smoking status, body mass index and abdominal circumference. Diabetes and hypertension duration were significantly higher in the CVD(+) group. Mean systolic and diastolic blood pressure, blood variability, dipper prevalence did not differ between study groups. Pulse pressure was significantly higher in the CVD(+) group compared to CVD(−) group (daytime pulse pressure 56.2±13.1 vs. 50.6±11.3 mmHg, p=0.003; nighttime pulse pressure 56.5±14.2 vs. 50.7±12.4 mmHg, p=0.005; 24-hour pulse pressure 54.7±13.6 vs. 49.0±12.0 mmHg, p=0.003).ConclusionsAmbulatory pulse pressure was significantly higher in patients with type 2 diabetes and atherosclerotic cardiovascular disease compared to those without cardiovascular disease, although mean systolic and diastolic blood pressure and blood pressure variability were similar.
