Sequential follow-up clinic and ambulatory blood pressure evaluation in a low risk population of white-coat hypertensive patients and in normotensives.
In subjects with white-coat hypertension (WCH) it is unclear how ambulatory blood pressure (ABPM) progresses over time and whether they exhibit an increased cardiovascular risk. ⋯ After 7.4 years of follow-up, both the progressive increase in ABPM and the rate of transition to ambulatory hypertension in subjects with WCH (either treated or untreated), who were selected under strict criteria were similar to that of normotensive subjects. Also there was no evidence that WCH exhibited a clear higher risk of development cardiovascular events.

Arm circumference in adults in Poland as an important factor influencing the accuracy of blood pressure readings.
The aim of this study was to assess the distribution of right arm circumference (RAC) in adults in Poland and to establish how often other than standard cuffs should be used in everyday practice. We also wanted to examine whether large cuffs are available in the market in Poland and whether the cuffs comply with WHO and JNC VII recommendations. ⋯ One-third of adults in Poland have an arm circumference, which requires use of a 'non-standard' sized cuff. Moreover, in patients with AH or overweight/obese subjects, wider or narrower cuffs should be used in approximately 40% of subjects.

ReviewBlood pressure measurement and the guidelines: a proposed new algorithm for the diagnosis of hypertension.
Current hypertension guidelines continue to base management decisions on the office BP as recorded by mercury sphygmomanometry. The imminent disappearance of mercury from the workplace for environmental and safety reasons provides an opportunity to re-assess how a diagnosis of hypertension is made. There are now several validated, automated BP recording devices available to replace mercury sphygmomanometers in the office setting. Self/home and 24-hour ambulatory BP monitoring should now become an integral part of the diagnostic algorithm for hypertension in view of their superior ability to predict clinical outcomes when compared to traditional office BP measurements.

Comparative StudyAccuracy of automated auscultatory blood pressure measurement during supine exercise and treadmill stress electrocardiogram-testing.
Monitoring of brachial blood pressure during exercise-electrocardiogram (ECG) testing is mandatory and changes in blood pressure (BP) can provide critical management evidence. Patient movement, mechanical vibration, artifactual sounds and observer variability make standard manual techniques problematic. This was an investigator-initiated study to assess an automated auscultatory technique of BP assessment [Tango exercise blood pressure monitor (SunTech Medical Instruments, NC, USA)] to adequately measure BP during stress-ECG testing. ⋯ Automated BP assessment during exercise-ECG testing is feasible with the use of appropriate automatic devices likely to be at least as accurate as manual BP registration. The Tango device is tolerant to exercise and provides reliable automatic BP assessment with absolute differences within an acceptable clinical range.

Clinical Trial Controlled Clinical TrialEffect of continuous positive airway pressure on ambulatory blood pressure in patients with obstructive sleep apnoea.
Previous reports on the effects of continuous positive airway pressure (CPAP) therapy for obstructive sleep apnoea (OSA) on blood pressure has shown contradictory results. Accordingly, we have investigated the effects of CPAP on blood pressure and on the potential reversal of the diagnosis of hypertension in patients with OSA evaluated repeatedly by ambulatory blood pressure monitoring. ⋯ The small reduction in blood pressure for consecutive profiles of ambulatory monitoring can probably be explained by the documented 'ABPM pressor effect' on patients using the ambulatory device for the first time. The high prevalence of hypertension among patients with OSA is not significantly reduced by treatment with CPAP. These results suggest that patients with OSA should always be properly evaluated for diagnosis of hypertension, and provided, if needed, with antihypertensive treatment apart from the recommended CPAP.
