Campaña de medida de la presión arterial (‘May Measurement Month’) 2019: análisis del cribado en farmacias comunitarias españolas y detección de hipertensión enmascarada / May Measurement Month 2019: Analysis of screening in Spanish community pharmacies and detection of masked hypertension

Objetivo: conocer dentro del proyecto May Measurement Month (MMM), la situación de la presión arterial (PA) en la población española, difundir la importancia de su medida periódica y estimar la prevalencia de hipertensión enmascarada (HEN). Métodos: estudio descriptivo transversal en farmacias comunitarias españolas durante mayo de 2019. Sujetos: usuarios adultos que consentían participar. Variables: presión arterial sistólica (PAS), presión arterial diastólica (PAD) en milímetros de mercurio (mmHg), frecuencia cardíaca (FC) en latidos/minuto (lat/min) A los participantes con PA ≥130/85 y <149/90 se les ofrecía realizar automedida (AMPA) para confirmar HEN. Resultados: 491 farmacéuticos recogieron 3.402 registros válidos (61,9% mujeres), edad media 56,6 años. 143 (4,2 %) nunca se habían medido la PA y 918 (27,0 %) no la habían medido en el último año. 1.047 tomaban antihipertensivos, de los que el 45,7 % tenían la PA alta. 780 (22,9 %) participantes tenían valores elevados de PA; ambos, 252 (7,4 %). La PASm fue 125,0 y la PADm 76,5 mmHg, mayor en hombres (p<0,001). La FCm fue de 72,6 lat/min. Se encontró relación directa entre PAS y PAD e IMC (p<0,0001). PADm y FCm fueron mayores en fumadores (p<0,0001). En pacientes diabéticos, PAS, PAD y FC fueron mayores. 61 participantes con sospecha de HEN aceptaron realizar AMPA. 25 (40,1 %) resultaron con PA ≥135/85 mmHg. Conclusiones: casi uno de cada cuatro participantes tenía valores de PA ≥140/90 mmHg. Los factores de riesgo relacionados más estrechamente con la PA elevada fueron sobrepeso, diabetes y edad. El 40 % de las sospechas de HEN se confirmaron mediante AMPA (AU)

Hipertensión enmascarada en niños con factores de riesgo de hipertensión arterial / Masked hypertension in children with risk factors for hypertension

INTRODUCCIÓN La hipertensión enmascarada (HE) en niños se define por registros de presión arterial (PA) normal en el consultorio y elevados fuera de él. El Monitoreo Ambulatorio de Presión Arterial de 24 horas (MAPA) permite su diagnóstico. Existe poca información reportada sobre su prevalencia en el ámbito local. OBJETIVOS Estimar la prevalencia de HE en niños con factores de riesgo para el desarrollo de hipertensión arterial (HTA). MÉTODOS Se realizó un estudio prospectivo observacional de corte transversal. Se incluyeron en forma consecutiva pacientes asistidos en forma ambulatoria en el Hospital General de Niños P. de Elizalde (HGNPE) entre el 1/7/2015 y el 15/10/2016, de 5 a 11 años de edad, con PA normal y al menos un factor de riesgo para desarrollar HTA (neonatal, personal y familiar). Se realizó MAPA durante 24 horas con dispositivo validado (monitor oscilométrico Spacelab modelo 90207 y 90217). Se estimó prevalencia de HE y su intervalo de confianza (IC95%) sobre el total de pacientes evaluados. El tamaño de muestra se estimó en 110 pacientes, con las aprobaciones pertinentes. RESULTADOS Se incluyó a 100 pacientes, con una edad promedio de 8,6±1,9 años; 56 eran mujeres. El tiempo promedio de MAPA fue 22,8±2,7 horas. Los factores de riesgo observados fueron antecedentes neonatales en 22 pacientes (parto prematuro, el más frecuente); todos tenían al menos un antecedente personal (los más frecuentes, ingesta aumentada de sal en 82 pacientes y obesidad en 73); 87 presentaron al menos un antecedente familiar (los más frecuentes, HTA y diabetes en 87 y 63 casos, respectivamente). El MAPA permitió identificar 10 pacientes con HE (10%; IC95%: 5,3-17,6%); 7 con hipertensión nocturna aislada (7%; IC95: 3,2-14%); y 23 como pre-hipertensión (23%; IC95: 15,8-32,2%). Los 10 pacientes con HE incluyeron 7 varones, 9 obesos y 8 con un antecedente familiar. DISCUSIÓN La prevalencia de HE en niños con factores de riesgo de desarrollar HTA fue del 10%. Es necesario completar el tamaño muestral para determinar si se mantiene esta prevalencia.

Introduction. Masked hypertension (MH) in children is defined as normal office blood pressure values and high values outside the clinical setting. The 24-hour ambulatory blood pressure monitoring (ABPM) is helpful for diagnosis. There is little information on MH prevalence in our population. Objective. To estimate the prevalence of MH in children with risk factors for arterial hypertension. Material and method. Prospective, observational, cross-sectional study. Patients seen at Hospital General de Niños "P. de Elizalde" between July 1st, 2015 and December 1st, 2016, aged 5-11 years, with normal blood pressure and at least one risk factor for arterial hypertension were included in consecutive order. A 24-hour ABPM was done (SpaceLabs 90207/90217). Estimated sample: 110 patients. All relevant authorizations were obtained. Results. One hundred and ten patients aged 8.7 ± 1.8 years were included; 60 were girls. ABPM duration: 23.18 ± 1.8 hours. Twenty-three patients had neonatal history; all had at least one factor corresponding to personal history (the most common ones were increased salt intake and obesity); 101 had at least one factor corresponding to family history. ABPM helped to identify 10 patients with MH (9.1%; 95% confidence interval --1;CI--3;: 5.1-15.9); 7 had isolated nocturnal hypertension (6.4%; 95% CI: 3.1-23.5) and 28 had prehypertension (25.4%; 95% CI: 18.234.3). Among the 10 patients with MH, 7 were boys, 9 were obese and had at least one factor corresponding to family history. Conclusion. The prevalence of MH in children with risk factors for arterial hypertension was close to 10%.

[Ambulatory blood pressure monitoring is a useful tool for all patients]. / La monitorización ambulatoria de la presión arterial es un instrumento aconsejable para todos los pacientes.

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.

Aspectos clínicos actuales del monitoreo ambulatorio de presión arterial / Current clinical aspects of ambulatory blood pressure monitoring

Resumen La hipertensión arterial sistémica es la enfermedad de mayor prevalencia a nivel mundial que incrementa de forma importante el riesgo cardiovascular. Un diagnóstico temprano, junto al logro de metas, disminuye de forma importante el riesgo de complicaciones. Recientemente se han actualizado los criterios diagnósticos para la hipertensión, así como la introducción del monitoreo ambulatorio de presión arterial. La introducción en la práctica clínica del monitoreo ambulatorio de presión arterial fue para ayudar al diagnóstico de la "hipertensión de bata blanca" y la "hipertensión enmascarada". En la actualidad también se ha demostrado que el monitoreo ambulatorio de presión arterial es superior al método tradicional de registro de presión arterial en el consultorio, tanto para el diagnóstico como para el adecuado control y ajuste del tratamiento farmacológico. Además se han introducido nuevos conceptos de suma importancia como la hipertensión arterial nocturna aislada, la elevación matutina alterada de la presión arterial y los patrones alterados de descenso nocturno de la presión arterial; los cuales se han asociado a un incremento de riesgo cardiovascular. Varios estudios han mostrado relevante valor pronóstico en algunas poblaciones. Aún existen otros conceptos en los cuales hace falta un mayor estudio para establecer adecuadamente su introducción en la práctica clínica como la carga hipertensiva, la variabilidad, la presión de pulso y la rigidez arterial; además de establecer valores de acuerdo a más estudios clínicos en poblaciones como pacientes geriátricos y niños.

Abstract Systemic arterial hypertension is the prevalentest disease worldwide that significantly increases cardiovascular risk. An early diagnosis together to achieve goals decreases the risk of complications significatly. Recently have been updated the diagnostic criteria for hypertension and the introduction of ambulatory blood pressure monitoring. The introduction into clinical practice of ambulatory blood pressure monitoring was to assist the diagnosis of "white coat hypertension" and "masked hypertension". Today has also shown that ambulatory blood pressure monitoring is better than the traditional method of recording blood pressure in the office, to the diagnosis and to adequate control and adjustment of drug treatment. Also there have been introduced important new concepts such as isloted nocturnal hypertension, morning blood pressure elevation altered and altered patterns of nocturnal dip in blood pressure; which have been associated with increased cardiovascular risk. Several studies have shown significant prognostic value in some stocks. There are still other concepts on which further study is needed to properly establish their introduction to clinical practice as hypertensive load variability, pulse pressure and arterial stiffness. In addition to setting values according to further clinical studies in populations such as elderly and children.

Prevalence of masked uncontrolled hypertension according to the number of office blood pressure measurements.

INTRODUCTION AND OBJECTIVES: The reported prevalence of masked uncontrolled hypertension (MUCH) varies because many studies are not comparable as they use different measurement methodologies. To evaluate the influence of the number of office blood pressure readings on the prevalence of MUCH we conducted a cross-sectional, multicenter study in treated hypertensive patients. PATIENTS AND METHODS: We carried out an observational, cross-sectional, multicenter study in 33 Spanish hospital-based hypertension units, involving 35 investigators and 12 Autonomous Communities. Six blood pressure readings and a 24-h ambulatory blood pressure monitoring were performed in treated hypertensive patients. The means of the first 3 readings (P123), the 2nd, 3rd and 4th readings (P234), the 3rd, 4th and 5th readings (P345) and the last 3 readings (P456) were compared with mean 24-h blood pressure. MUCH was defined as office blood pressure <140/90mmHg and 24-h blood pressure ≥130/80mmHg, considering the first 3 readings (MUCH123), the 2nd, 3rd and 4th readings (MUCH234), the 3rd, 4th and 5th readings (MUCH345) and the last 3 readings (MUCH456). RESULTS: We included 498 hypertensive patients. Mean (standard deviation) office blood pressure measurements were: (P123) 141(18)/82(11); (P234) 139(17)/81(11); (P345) 138(17)/81(11) and (P456) 137(16)/80(10) mmHg. Mean 24-h blood pressure was 127(13.8)/75(9.5) mmHg. The correlation coefficients between ambulatory and office systolic/diastolic blood pressure were (P123):0.48/0.50; (P234):0.50/0.52; (P345):0.50/0.54; and (P456):0.50/0.55 (p<0.001, all). The prevalences of MUCH123, MUCH234, MUCH345 and MUCH456 were 14.5%, 18.9%, 19.5% and 21.1%, respectively. CONCLUSIONS: The prevalence of MUCH diagnosis depends on the serial office blood pressure readings, being much higher for the last three blood pressure readings. Discarding the first and second office blood pressure measures seems to be the most accurate method for diagnosing MUCH.

Estado actual del monitoreo ambulatorio de presión arterial

Resumen El monitoreo ambulatorio de presión arterial es una importante herramienta clínica, ya que mejora el diagnóstico de hipertensión arterial, detecta su presentación enmascarada así como su forma nocturna aislada, al igual que el ascenso matinal exagerado de la presión arterial, situaciones estas con implicancias pronóstico-terapéuticas. Mediante este estudio es posible diagnosticar la hipertensión de túnica blanca, particularmente frecuente en las primeras etapas del embarazo, evitando de esa forma tratamientos innecesarios. Dado que en las mujeres el control de la hipertensión arterial nocturna tiene marcado impacto en la reducción de eventos, este estudio debería ser considerado en todas quienes presentan hipertensión arterial o se tiene sospecha de ello. Todo esto ha llevado a que en el momento actual el monitoreo ambulatorio de presión arterial constituya un valioso aliado en el cuidado de la salud de los pacientes.

Summary Ambulatory blood pressure monitoring is an important clinical tool, as well as improving the diagnosis of hypertension, detect its masked presentation, its isolated nocturnal form and exaggerated morning surge in blood pressure, all situations with therapeutic and prognostic implications. Through this study it is possible to diagnose white coat hypertension, a situation particularly common in early pregnancy, thus avoiding unnecessary treatments. Since in women nocturnal hypertension control has marked impact in reducing events, this study should be considered in all those with hypertension or suspected it. All this makes the ambulatory blood pressure monitoring a valuable associate in patients' health care.

Recomendaciones conjuntas de la International Society for Chronobiology (ISC), American Association of Medical Chronobiology and Chronotherapeutics (AAMCC), Sociedad Española de Cronobiología Aplicada, Cronoterapia y Riesgo Vascular (SECAC), Sociedad Española de Arteriosclerosis (SEA) y Romanian Society of Internal Medicine (RSIM).

Correlation between systolic (SBP) and diastolic (DBP) blood pressure (BP) level and target organ damage, cardiovascular disease (CVD) risk, and long-term prognosis is much greater for ambulatory BP monitoring (ABPM) than daytime office measurements. The 2013 ABPM guidelines specified herein are based on ABPM patient outcomes studies and constitute a substantial revision of current knowledge. The asleep SBP mean and sleep-time relative SBP decline are the most significant predictors of CVD events, both individually as well as jointly when combined with other ABPM-derived prognostic markers. Thus, they should be preferably used to diagnose hypertension and assess CVD and other associated risks. Progressive decrease by therapeutic intervention in the asleep BP mean is the most significant predictor of CVD event-free interval. The 24 h BP mean is not recommended to diagnose hypertension because it disregards the more valuable clinical information pertaining to the features of the 24 h BP pattern. Persons with the same 24 h BP mean may display radically different 24 h BP patterns, ranging from extreme-dipper to riser types, representative of markedly different risk states. Classification of individuals by comparing office with either the 24 h or awake BP mean as "masked normotensives" (elevated clinic BP but normal ABPM), which should replace the terms of "isolated office" or "white-coat hypertension", and "masked hypertensives" (normal clinic BP but elevated ABPM) is misleading and should be avoided because it disregards the clinical significance of the asleep BP mean. Outcome-based ABPM reference thresholds for men, which in the absence of compelling clinical conditions are 135/85 mmHg for the awake and 120/70 mmHg for the asleep SBP/DBP means, are lower by 10/5 mmHg for SBP/DBP in uncomplicated, low-CVD risk, women and lower by 15/10 mmHg for SBP/DBP in male and female high-risk patients, e.g., with diabetes, chronic kidney disease (CKD), and/or past CVD events. In the adult population, the combined prevalence of masked normotension and masked hypertension is >35%. Moreover, >20% of "normotensive" adults have a non-dipper BP profile and, thus, are at relatively high CVD risk. Clinic BP measurements, even if supplemented with home self-measurements, are unable to quantify 24 h BP patterning and asleep BP level, resulting in potential misclassification of up to 50% of all evaluated adults. ABPM should be viewed as the new gold standard to diagnose true hypertension, accurately assess consequent tissue/organ, maternal/fetal, and CVD risk, and individualize hypertension chronotherapy. ABPM should be a priority for persons likely to have a blunted nighttime BP decline and elevated CVD risk, i.e., those who are elderly and obese, those with secondary or resistant hypertension, and those diagnosed with diabetes, CKD, metabolic syndrome, and sleep disorders.
