Hypertension (HT) is the most important risk factor in the development of cardiovascular disease. Classically diagnosis and management have been based on conventional office blood pressure (BP) but it has as main limitation that only offers information of a particular time and presents multiple biases dependent on inherent variability of blood pressure and measurement technique itself. Ambulatory blood pressure monitoring (ABPM) consists of performing multiple measurement of blood pressure, performed automatically, outside the medical setting, during the normal activities of the individual and in a 24-hour period. Multiple studies have demonstrated the prognosis superiority in the development of cardiovascular disease of ABPM, it allows detection of white coat HT as well, avoiding overdiagnosis and overtreatment and the detection of patients with masked H T, who contrarily are at risk of underdetection and undertreatment. Also it provides nighttime BP and circadian variability that provides additional prognostic value. © 2017 SEHLELHA. Published by Elsevier España, S.L.U.

Clinical blood pressure measurement (BP) is an occasional and imperfect way of estimating this biological variable. Ambulatory blood pressure monitoring (ABPM) is by far the best clinical tool for measuring an individual's blood pressure. Mean values over 24h, through the daytime and at night all make it more possible to predict organic damage and the future development of the disorder. ABPM enables the detection of white-coat hypertension and masked hypertension in both the diagnosis and follow-up of treated patients. Although some of the advantages of ABPM can be reproduced by more automated measurement without the presence of an observer in the clinic or self-measurement at home, there are some other elements of great interest that are unique to ABPM, such as seeing what happens to a patient's BP at night, the night time dipping pattern and short-term variability, all of which relate equally to the patient's prognosis. There is no scientific or clinical justification for denying these advantages, and ABPM should form part of the evaluation and follow-up of practically all hypertensive patients. Rather than continuing unhelpful discussions as to its availability and acceptability, we should concentrate our efforts on ensuring its universal availability and clearly explaining its advantages to both doctors and patients., (Copyright © 2016 SEH-LELHA.

It is clear that clinical measurements of blood pressure can lead to errors in the diagnostic process and follow-up of patients with hypertension. Scientific societies recommend other measurement methods, such as home measurements and outpatient monitoring. Outpatient monitoring might be the golden standard but, nowadays has an important limitation-its availability. Home measurements solve 80-90% of the doubts of the diagnostic process and follow-up of patients with hypertension, and its higher availability and acceptance by the patient are clear. Home measurements should be used in the diagnostic process of arterial hypertension as a screening test for white coat hypertension and masked hypertension. They should be used as a screening test for resistant hypertension in the follow-up of patients with high blood pressure. Besides, in the follow-up of patients with hypertension home measurements have shown that they can contribute to treatment adherence, reduce clinical inertia and make data teletransmission possible, aspects that have proven to help improve the degree of control of hypertensive patients. Therefore, home measurements would be the treatment of choice for the diagnosis and follow-up of most patients with hypertension. We should consider home measurements and outpatient monitoring as complementary methods for the diagnosis and follow-up of patients with high blood pressure., (Copyright © 2016.
