“…A proposed alternative to a full 24-hour ABPM session has been shorter duration sessions that can predict the 24-hour mean blood presure 13,19–21. Truncated ABPM sessions were first shown to be predictive of full 24-hour ABPM sessions in 1982 19.…”

Ambulatory blood pressure monitoring (ABPM) is an accurate method for evaluating hypertension, yet its use in clinical practice may be limited by availability, cost, and patient inconvenience. The objective of this study was to investigate the ability of a 6-hour ABPM window to predict blood pressure control, based on that of the full 24-hour ABPM session across several clinical indications in a cohort of 486 patients referred for ABPM. Sensitivities and specificities of the 6-hour systolic blood pressure mean to accurately classify patients as hypertensive were determined using a fixed reference point of 130 mmHg for the 24-hour mean. For four common indications in which ABPM was ordered, prediction tables were constructed varying the thresholds for the 6-hour mean to find the optimal value that best predicted the 24-hour hypertensive status as determined from the full 24-hour interval. Using a threshold of 137 mmHg for the indications of borderline hypertension, evaluation of current antihypertensive regimen and suspected white-coat hypertension, sensitivity and specificity ranged from 0.83–0.88 and 0.80–0.88, respectively, for the ability of 6-hour ABPM to correctly categorize hypertensive status. Using 133 mmHg as the threshold for treatment resistance resulted in a sensitivity and specificity of 0.93 and 0.83, respectively. We conclude that a shortened ABPM session of 6 hours can be used to accurately classify blood pressure as controlled or not, based on the results of a 24-hour session. The optimal 6-hour threshold for comparison depends upon indication for referral.

“…The LABPM results were found to be durable when studied in 22 patients who had two 24-h ABPM done 2 months apart. Further support of LABPM comes from the work of Chanudet et al [20], who looked at the utility of shortterm ambulatory monitoring in a study of 354 males with normal to mild elevations of blood pressure. The 24-h ABPM has been proposed as the best tool to diagnose and assess the effectiveness of treatment of the hypertensive patient.…”

Limited (6-h) ambulatory blood pressure monitoring is a valid replacement for the office blood pressure by trained nurse clinician in the diagnosis of hypertension

Limited ambulatory blood pressure monitoring is an excellent replacement for office blood pressure, done to American Heart Association criteria, in diagnosing hypertension. This avoids issues of variability introduced by the observers, such as digit preference and bias, and increases reproducibility of blood pressure measurements. The appropriate normal value for limited ambulatory blood pressure monitoring is <140/90 mmHg compared with <135/85 mmHg used in 24-h ambulatory blood pressure monitoring.

“…14 evaluated whether the monitoring of arterial pressure could be done in shorter periods of time and concluded that during the daytime (10 to 22 hours) monitoring could be performed for 4 hours and the night monitoring (3-7hs) for 2 hours because these periods have a good correlation with the usual periods 14 . It is valid to question the importance of the influence of the siesta in the determination of BP averages and pressure loads during 24 hour monitoring of arterial pressure, as the values are small.…”

Objective -To evaluate the influence of the siesta in ambulatory blood pressure (BP) Ambulatory arterial blood pressure (BP) monitoring is a test for evaluating arterial blood pressure over a 24 hours period while the patient carries out his or her routine activities, including sleeping. It is a useful test for the diagnosis of arterial hypertension, because it eliminates white coat hypertension and evaluates the efficiency of BP treatment during a 24 hours period 1 . This methodology, by intermittently evaluating arterial pressure, allows observation of the circadian variation in arterial pressure with higher levels during wakefulness and lower ones during sleep.Reduction in arterial blood pressure levels during sleep occurs in most individuals, who are called dippers. Individuals who do not experience a reduction in arterial pressure during sleep are called nondippers. O'Brien et al.2 in 1988 in a letter to the editor reported that he evaluated the reduction in arterial pressure during sleep with the use of arterial blood pressure monitoring and found that of 123 hypertensive patients 17.1% did not have a difference of at least 10/ 5mmHg between the average of systolic and diastolic pressures in the wakeful period and sleep. Pickering 3 stresses that in the majority of hypertensive patients the pattern of wakefulness and sleep is consistent with higher pressure values during wakefulness and lower ones during sleep. Staessen et al. 4 extended the study of pressure reduction during sleep by analyzing 7,320 hypertensive and normotensive subjects from an international database. Results showed that for all individuals the reduction of systolic/ diastolic pressure during sleep was 16.7±11/13.6±8mmHg 4 . In addition, the reduction was greater in borderline and treated hypertensives than in normotesives, in men than women, in Europeans than in individuals from other continents and in readings made with an oscilometric apparatus than those made with an auscultatory apparatus. 17 . It was also observed that the reduction is smaller in elderly than in young people. An analysis 5 of the night/day relation, defined as the relation of night/day pressure multiplied by 100 expressing the nocturnal pressure as a percentage of diurnal pressure verified that 2.5% of normotensive, 4.4% of borderline hypertensives and 4.4% of treated hypertensives
