Correlation between Very Short and Short-Term Blood Pressure Variability in Diabetic-Hypertensive and Healthy Subjects.

Background: Blood pressure (BP) variability can be evaluated by 24-hour ambulatory BP monitoring (24h-ABPM), but its concordance with results from finger BP measurement (FBPM) has not been established yet.

Objective: The aim of this study was to compare parameters of short-term (24h-ABPM) with very short-term BP variability (FBPM) in healthy (C) and diabetic-hypertensive (DH) subjects.

Methods: Cross-sectional study with 51 DH subjects and 12 C subjects who underwent 24h-ABPM [extracting time-rate, standard deviation (SD), coefficient of variation (CV)] and short-term beat-to-beat recording at rest and after standing-up maneuvers [FBPM, extracting BP and heart rate (HR) variability parameters in the frequency domain, autoregressive spectral analysis].

White coat effect and masked uncontrolled hypertension in treated hypertensive-diabetic patients: Prevalence and target organ damage.

Background: The association between hypertensive phenotypes of controlled hypertension (CH), white-coat effect (WCE), masked uncontrolled hypertension (MUH) and sustained hypertension (SH) with target organ damage have not been clearly established in diabetic hypertensive treated patients. The present study aims to evaluate the prevalence of the four phenotypes considering the current cut-off points for office and 24 h-ambulatory blood pressure monitoring (ABPM) and the association with left ventricle hypertrophy (LVH), diastolic function and nephropathy.

Methods: Cross-sectional study with 304 patients on anti-hypertensive treatment aged 57.
