    No consensus has emerged among different guidelines concerning how many blood pressure (BP) measurements should be performed at office visits in the diagnosis of hypertension. The purpose of this study was to examine the compatibility of various multiple average office BP measurements and 24-h BP monitoring (ABPM) in patients followed up in the posthoc analysis of the Cappadocia hypertension cohort. A total 1158 office BP measurements by 207 patients were examined. The results were then classified as G1 (average of the 1st and 2nd BP), G2 (average of the 2nd and 3rd), G3 (average of the 2nd, 3rd, and 4th), G4 (average of the 2nd, 3rd, 4th, and 5th), and G5 (average of all five measurements). Compatibility between the average values in the groups and concomitant 24-h ABPM data was examined. While a significant difference was observed between daytime 24-h ABPM SBP and G1 (p = .002), no difference was found in the other groups. Office DBP approached the daytime 24-h ABPM values as the number of measurements in the five groups increased, although average office DBP data in all groups were higher than daytime 24-h ABPM DBP (p = .000 for all). In light of our study results, we recommend that three office BP measurements be performed and that the average of the 2nd and 3rd measurements be used for SBP, while in terms of DBP, we recommend that as many measurements as possible be taken without the 1st value being included in the average.

    The Effect of Ambient Air Pollution on Office, Home, and 24-Hour Ambulatory Blood Pressure Measurements

    Background Air pollution has recently been linked to a number of cardiovascular diseases, particularly hypertension (HT). In our study, we aimed to evaluate the association between air pollution and blood pressure (BP) and compare the relationship of BP measurement results obtained using different methods (office, home, and 24-hour ambulatory BP monitoring [ABPM]). Methods This retrospective nested panel study performed with prospective Cappadocia cohort data investigated the relationships between particulate matter (PM) 10 and sulfur dioxide (SO2) and concurrent home, office, and 24-hour ABPM data at each control performed over a 2-year period. Results A total of 327 patients in the Cappadocia cohort were included in this study. On the day of office blood pressure measurement, there was an increase of 1.36 mm Hg in systolic BP and 1.18 mm Hg in diastolic BP for every 10 mu m/m(3) rise in SO2 values. A mean 3-day 10 mu m/m(3) increase in SO2 was linked to an increase of 1.60 mm Hg in systolic BP and 1.33 mm Hg in diastolic BP. A 10 mu m/m(3) rise in mean SO2 on the day of 24-hour ABPM measurement was found to be associated with an increase of 1.3 mm Hg in systolic BP and 0.8 mm Hg in diastolic BP. SO2 and PM 10 had no effect on home measurements. Conclusion In conclusion, increased SO2 levels, during winter months in particular, can be associated with an elevation in office BP values. Our study findings show that air pollution in the setting in which BP is measured may be associated with the results.

    The effect of intermittent fasting on blood pressure variability in patients with newly diagnosed hypertension or prehypertension
    (Elsevier Science Inc, 2018) Erdem, Yunus; Özkan, Gülsüm; Ulusoy, Sükrü; Arici, Mustafa; Derici, Ulver; Şengül, Sule; Ertürk, Sehsuvar
    Intermittent fasting is a phenomenon which can be observed in most humans. The effect of intermittent fasting on blood pressure variability (BPV) has not previously been investigated. The purpose of this study was to assess the effect of fasting on blood pressure (BP) (with office, home, central, and ambulatory blood pressure monitoring [ABPM]) and on BPV. Sixty individuals were included in the study. Office, home, ABPM, and central BP measurements were performed before and during intermittent fasting. Standard deviation and coefficient variation were used for office and home BPV measurement, while the smoothness index was used to calculate ABPM variability. Patients' BP and BPV values before and during intermittent fasting were then compared. Intermittent fasting resulted in a significant decrease in office BP values and ABPM measurements but caused no significant change in home and central BP measurements. Twenty-four hour urinary sodium excretion decreased. Smoothness values obtained from ABPM measurements were low; in other words, BPV was greater. BPV was higher in patients who woke up to eat before sunrise, but BPV was low in patients with high body mass index. Intermittent fasting produced a significant decrease in BP values in terms of office and ABPM measurements in this study but caused no significant change in central BP and home measurements. We also identified an increase in BPV during intermittent fasting, particularly in patients who rose before sunrise. (C) 2017 American Society of Hypertension. All rights reserved.
