Comparative Study Clinical Trial Controlled Clinical TrialEffect of standard cuff on blood pressure readings in patients with obese arms. How frequent are arms of a 'large circumference'?
To measure the effect on blood pressure readings when a standard cuff is used on patients with arms of a large circumference, and to determine the frequency of arms of a large circumference. ⋯ There is an overestimation of blood pressure when a standard cuff is used in obese subjects. The high prevalence of these individuals in our environment, both in the hypertensive and normotensive population, makes it necessary to have on hand different sizes of cuffs for taking blood pressure in order to avoid incorrect decisions.

ReviewNon-invasive beat-to-beat blood pressure monitoring: new developments.
Continuous blood pressure monitoring is an essential prerequisite for any study on blood pressure variability. Invasive procedures are no longer acceptable for research projects in a clinical setting, and recently developed devices able to record blood pressure on a beat-by-beat basis in a non-invasive fashion may represent valuable alternative tools. This article will briefly review the available information on the most recent advances in this field. It will focus on further developments of the original technology for finger blood pressure monitoring introduced by Penáz, as well as on newer devices that have been proposed over the last few years for non-invasive cardiovascular monitoring both in research and in clinical studies.

Comparative StudyUse of radial arterial tonometric continuous blood pressure measurement in cardiovascular reactivity studies.
Non-invasive continuous blood pressure monitoring has, for the past decade, been performed using the Finapres monitor. Radial tonometry is a new methodology for measuring non-invasive beat-to-beat blood pressure. This technique has been evaluated for other applications, but its use in cardiovascular reactivity testing has not yet been reported. ⋯ Radial tonometric continuous beat-to-beat blood pressure monitoring with the Colin Pilot was associated with a low artifact rating and high accuracy of blood pressure measurement during reactivity testing.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialAn ambulatory blood pressure monitoring study of the comparative antihypertensive efficacy of two angiotensin II receptor antagonists, irbesartan and valsartan.
The primary objective of this study was to compare the change from baseline in mean diastolic ambulatory blood pressure (ABP) at 24 h post dose (trough measurement) after 8 weeks of treatment with irbesartan or valsartan in subjects with mild-to-moderate hypertension. Secondary objectives included comparing the mean changes from baseline in systolic ABP at trough; 24-h ABP; morning and night-time ABP; self-measured systolic blood pressure (SBP) and diastolic blood pressure (DBP); and office-measured SBP and DBP at trough. ⋯ Irbesartan was more effective than valsartan in reducing DBP and SBP at trough and in providing greater overall 24-h blood pressure-lowering efficacy.
