Morbilidad oculta por hipertensión arterial en adolescentes. Importancia del monitoreo ambulatorio de presión arterial / Hidden morbidity due to arterial hypertension in adolescents. Importance of ambulatory blood pressure monitoring

El diagnóstico de un niño o adolescente como hipertenso no es tarea fácil. El principal medio para el diagnóstico de hipertensión arterial sigue siendo la presión arterial tomada en el consultorio, pero por su escasa reproducibilidad, este método tiene algunas limitaciones. Existen otros menos usados en el medio pediátrico, pero más reproducibles y confiables, como el monitoreo ambulatorio de la presión arterial, el cual permite disminuir el subdiagnóstico de hipertensión arterial. La investigación se realizó a partir de un pesquisaje efectuado con el objetivo de identificar la morbilidad oculta de hipertensión arterial en adolescentes con exceso de peso, en el área de salud del Policlínico «Chiqui Gómez Lubián», Santa Clara, Villa Clara. El caso reviste importancia para la Atención Primaria de Salud, promueve la utilización de un método diagnóstico que mejora la correcta clasificación y tratamiento de la hipertensión en edades tempranas para contribuir a la prevención de complicaciones posteriores

Diagnosing a child or an adolescent as hypertensive is not an easy task. The main way to diagnose arterial hypertension continues to be at the doctor´s office, but due to its poor reproducibility, this method has some limitations. There are other less used methods in the pediatric setting, but are more reproducible and reliable, such as ambulatory blood pressure monitoring, which makes it possible to reduce the underdiagnosis of arterial hypertension. We present a case of a male adolescent who was detected during a screening, with the objective of identifying hidden morbidity of arterial hypertension in overweight adolescents, in the health area at "Chiqui Gómez Lubián" Polyclinic, in Santa Clara, Villa Clara. The case is of great important for primary health care, promotes the use of a diagnosis method that improves the correct classification and treatment of hypertension at an early age and contributes to the prevention of subsequent complications

Awareness and recommendation of home blood pressure measurement among physicians in India: Results from Asia HBPM survey 2020

Background: Awareness of hypertension and blood pressure (BP) control rates are still low in India. Home blood pressure monitoring (HBPM) is recognized as a valuable tool to diagnose and support hypertension treatment including the prevention of cardiovascular diseases(CVD) and target organ damage. We explored the prevailing knowledge and current recommendation of HBPM in daily practice by physicians in India. Materials and methods: As part of Asia HBPM Survey 2020, a cross-sectional survey was conducted among healthcare providers from India between June 2020 to June 2021. The questionnaire consisted of 37 questions and sub-questions related to HBPM awareness and recommendations to patients. Results: A total of 832 physicians participated in the survey. Almost 83% were male, whereas age, specialty and workplace were well distributed. 31.3% of physicians instruct their patients to measure their BP before taking antihypertensive drugs, while around 30% of physicians gave no instructions. The reference value of hypertension diagnosis amongst the physicians was substantially low based on clinic BP (34.4%) and home BP (15.1%). Among physicians who manage hypertensive patients, nearly 88% recommend HBPM to their patients, however, only 34.9% of their patients own HBPM device and 30.4% of the patients measure their own BP at home. Conclusion: The survey reveals that HBPM instructions to the patients are either lacking or not well aligned with the local hypertension guidelines which may have led to the low HBPM use among patients. Clear and practical educational material and sessions are needed to improve the understanding of HBPM amongst physicians

Arterial hypertension in kidney transplantation: huge importance, but few answers / Hipertensão arterial no transplante renal: grande importância, mas poucas respostas

Abstract Arterial hypertension (AH) after renal transplantation (RTX) is correlated with worse cardiovascular and renal outcomes, with loss of renal function, decreased graft survival and higher mortality. RTX recipients have discrepant blood pressure (BP) values when measured in the office or by systematic methodologies, such as Ambulatory Blood Pressure Monitoring (ABPM), with significant prevalence of no nocturnal dipping or nocturnal hypertension, white coat hypertension and masked hypertension. The aim of the present study was to review the issue of hypertension in RTX, addressing its multifactorial pathophysiology and demonstrating the importance of ABPM as a tool for monitoring BP in these patients. Treatment is based on lifestyle changes and antihypertensive drugs, with calcium channel blockers considered first-line treatment. The best blood pressure target and treatment with more favorable outcomes in RTX are yet to be determined, through well-conducted scientific studies, that is, in terms of AH in RTX, we currently have more questions to answer than answers to give.

Resumo Hipertensão arterial (HA) no póstransplante renal (TXR) se correlaciona com piores desfechos cardiovasculares e renais, com perda de função renal, diminuição da sobrevida do enxerto e maior mortalidade. Receptores de TXR apresentam valores discrepantes de pressão arterial (PA) quando ela é obtida em consultório ou por metodologias sistematizadas, como a Monitorização Ambulatorial da PA (MAPA), com prevalências significantes de ausência de descenso noturno ou hipertensão noturna, hipertensão do avental branco e hipertensão mascarada. O objetivo do presente estudo foi rever a temática da hipertensão no TXR, abordando sua fisiopatologia multifatorial e demonstrando a importância da MAPA como ferramenta de acompanhamento da PA nesses pacientes. O tratamento é baseado em mudanças no estilo de vida e em fármacos anti-hipertensivos, sendo os bloqueadores de canais de cálcio considerados de primeira linha. A melhor meta pressórica e o tratamento com desfechos mais favoráveis no TXR ainda estão por ser determinados, por meio de estudos bem conduzidos cientificamente, ou seja, em termos de HA no TXR temos atualmente mais questões a responder do que respostas a dar.

Clinical value of regional cerebral oxygen saturation combined with electrophysiological blood pressure monitoring in patients with carotid artery stenosis and coronary heart disease during carotid endarterectomy / 中国医师进修杂志

Objective:To investigate the effect of regional cerebral oxygen saturation (rSO 2) combined with neurophysiological blood pressure monitoring on brain protection and myocardial protection during carotid endarterectomy (CEA) in patients with carotid stenosis and coronary heart disease. Methods:One hundred patients with carotid artery stenosis complicated with coronary heart disease treated in Jinhua Central Hospital from June 2021 to June 2022 were randomly divided into control group and experimental group. All patients were scheduled to undergo CEA. Fifty patients in the control group were administered with empirically increasing basic blood pressure by 20% - 30%, and 50 patients in the experimental group were administered with blood pressure under the guidance of rSO 2 combined with motor evoked potentials (MEPs) and somatosensory evoked potentials (EPS). The neurological function indexes of the two groups [neuron specific enolase (NSE), central nerve specific protein (S100-β)], myocardial function indicators [cardiac troponin I (cTnI), B-type natriuretic peptide (BNP)], clinical indicators (eye opening time, extubation time, recovery room stay time, hospital stay) and the incidence of postoperative complications [delirium (POD), cognitive dysfunction (POCD), neurological impairment] were compard between the two groups. Results:Two sets of postoperative NSE and S100-β both increased ( P<0.05), but NSE and S100 in the experimental group after surgery were lower than those in the control group: (0.82 ± 0.14) μg/L vs. (1.18 ± 0.28) μg/L, (290.13 ± 27.25) mg/L vs. (301.98 ± 28.56) mg/L, the differences were statistically significant ( P<0.05). After surgery, cTnI and BNP increased in both groups ( P<0.05), but the cTnI and BNP in the experimental group were lower than those in the control group: (2.87 ± 0.74)] μg/L vs. (3.36 ± 0.83) μg/L, (3.01 ± 0.85) μg/L vs. (3.89 ± 0.92) μg/L, the differences were statistically significant ( P<0.05). The opening time, extubation time, recovery room stay time, and hospitalization time in the experimental group were shorter than those in the control group: (16.79 ± 3.15) min vs. (20.55 ± 3.83) min, (29.38 ± 4.66) min vs. (40.14 ± 4.57) min, (66.82 ± 15.80) min vs. (89.35 ± 24.78) min, (11.24 ± 4.89) d vs. (14.56 ± 6.74) d, there were statistical differences ( P<0.05). The incidence of postoperative complications in the experimental group was lower than that in the control group: 12.00% (6/50) vs. 28.00% (14/50), there was statistical difference ( P<0.05). Conclusions:The application of rSO 2 combined with neurophysiological blood pressure monitoring in CEA of patients with carotid artery stenosis and coronary heart disease has a good effect, which has brain protection and myocardial protection, can shorten the recovery time of anesthesia and hospitalization time, and reduce the incidence of postoperative complications.

Relação da Ascensão Matinal da Pressão Arterial com a Hipertrofia Ventricular Esquerda em Hipertensos Obesos / Association between Morning Surge and Left Ventricular Hypertrophy in Obese Hypertensive Patients

Resumo Fundamento O aumento do peso frequentemente desencadeia mecanismos que elevam a pressão arterial. A obesidade causa mudanças estruturais no miocárdio, incluindo aumento da massa ventricular, dilatação atrial, bem como disfunções diastólicas e sistólicas. Além disso, variações pressóricas nos hipertensos obesos, como a ascensão matinal (AM), podem ter relevância clínica na prevenção dos eventos cardiovasculares. A AM da pressão arterial é um fenômeno fisiológico, que quando elevada pode ser considerada um fator de risco independente para eventos cardiovasculares. Objetivo Avaliar valores da elevação da AM e sua associação com a hipertrofia ventricular esquerda (HVE) e com o Descenso do Sono (DS) em obesos e não obesos hipertensos. Métodos Estudo transversal que avaliou medidas pressóricas à monitorização ambulatorial da pressão arterial (MAPA) e a presença de HVE, avaliada pela ecocardiografia, em 203 pacientes hipertensos em tratamento ambulatorial, separados em dois grupos: 109 não obesos e 94 hipertensos obesos. O nível de significância adotado foi de 0,05 em testes bicaudais. Resultados A AM acima de 20 mmHg à MAPA foi detectada em 59,2% dos pacientes do grupo "não obesos" e em 40,6% no grupo "obesos". A HVE foi encontrada em 18,1% no grupo dos não-obesos e em 39,3% no grupo de obesos, p<0,001. No grupo "obesos" foi observado que AM >16 mmHg esteve associada à HVE, com [razão de prevalência: 2,80; IC95% (1,12-6,98), p=0,03]. Para o grupo dos "não obesos", o ponto de corte da AM para essa associação foi >22 mmHg. Conclusão A AM elevada associou-se positivamente com HVE, com comportamento peculiar na população de hipertensos e obesos.

Abstract Background Weight gain can trigger mechanisms that increase blood pressure. Nevertheless, obesity causes structural changes in the myocardium, including increased ventricular mass, atrial dilatation, and diastolic and systolic dysfunction. Additionally, blood pressure variations, like morning surge (MS) in obese hypertensive patients may have clinical relevance in cardiovascular events. Although morning blood pressure surge is a physiological phenomenon, excess MS can be considered an independent risk factor for cardiovascular events. Objective To evaluate MS values and their association with left ventricular hypertrophy (LVH) and nocturnal dipping (ND) in obese and non-obese hypertensive patients. Methods A cross-sectional study that evaluated BP measurements by ambulatory blood pressure monitoring (ABPM) and the presence of LVH by echocardiography in 203 hypertensive outpatients, divided into two groups: 109 non-obese and 94 obese hypertensives patients. The significance level was set at 0.05 in two-tailed tests. Results A MS above 20 mmHg by ABPM was detected in 59.2% of patients in the non-obese group and 40.6% in the obese group. LVH was found in 18.1% and 39.3% of patients in the non-obese and obese groups, respectively, p<0.001. In the "obese group", it was observed that a MS>16 mmHg was associated with LVH, [prevalence ratio: 2.80; 95%CI (1.12-6.98), p=0.03]. For the non-obese group, the cut-off point of MS for this association was >22 mmHg. Conclusion High MS was positively associated with LVH, with a particular behavior in the hypertensive obese group.

A Relação entre o Estado Dipping Noturno, Aumento da Pressão Arterial Matinal e Internações Hospitalares em Pacientes com a Insuficiência Cardíaca Sistólica / The Relationship between Nocturnal Dipping Status, Morning Blood Pressure Surge, and Hospital Admissions in Patients with Systolic Heart Failure

Resumo Fundamento A hipertensão é um fator de risco conhecido para o desenvolvimento de insuficiência cardíaca. No entanto, há dados limitados para investigar a associação entre pico de pressão arterial matinal (PPAM), estado dipper, parâmetros ecocardiográficos e internações hospitalares em pacientes com insuficiência cardíaca sistólica. Objetivos Avaliar a relação entre aumento matinal da pressão arterial, padrão de pressão arterial não-dipper, parâmetros ecocardiográficos e internações hospitalares em pacientes com insuficiência cardíaca sistólica. Métodos Analisamos retrospectivamente os dados de 206 pacientes consecutivos com hipertensão e fração de ejeção do ventrículo esquerdo abaixo de 40%. Dividimos os pacientes em dois grupos de acordo com os resultados da monitoramento ambulatorial da pressão arterial (MAPA) de 24 horas: dippers (n=110) e não-dippers (n=96). O aumento matinal da pressão arterial foi calculado. Achados ecocardiográficos e internações hospitalares durante o acompanhamento foram anotados. A significância estatística foi definida como p < 0,05. Resultados O grupo de estudo foi composto por 206 pacientes com predominância do sexo masculino e idade média de 63,5 ± 16,1 anos. O grupo não-dipper teve significativamente mais internações hospitalares em comparação com os dippers. Houve correlação positiva entre PPAM e índice de volume do átrio esquerdo (r=0,331, p=0,001), relação entre velocidade de influxo mitral precoce e velocidade de propagação do fluxo (r= 0,326, p=0,001) e relação entre influxo mitral precoce velocidade e velocidade diastólica inicial do anel mitral (E/Em) (r= 0,314, p=0,001). Verificou-se que a PA não-dipper, PPAM e o padrão E/Em estão independentemente associados ao aumento das admissões hospitalares. Conclusão O PPAM está associado à disfunção diastólica e pode ser um preditor sensível de internação hospitalar em pacientes com insuficiência cardíaca sistólica.

Abstract Background Hypertension is a known risk factor for developing heart failure. However, there is limited data to investigate the association between morning blood pressure surge (MBPS), dipping status, echocardiographic parameters, and hospital admissions in patients with systolic heart failure. Objectives To evaluate the relationship between morning blood pressure surge, non-dipper blood pressure pattern, echocardiographic parameters, and hospital admissions in patients with systolic heart failure. Methods We retrospectively analyzed data from 206 consecutive patients with hypertension and a left ventricular ejection fraction below 40%. We divided the patients into two groups according to 24-hour ambulatory blood pressure monitoring (ABPM) results: dippers (n=110) and non-dippers (n=96). Morning blood pressure surge was calculated. Echocardiographic findings and hospital admissions during follow-up were noted. Statistical significance was defined as p < 0.05. Results The study group comprised 206 patients with a male predominance and mean age of 63.5 ± 16.1 years. The non-dipper group had significantly more hospital admissions compared to dippers. There was a positive correlation between MBPS and left atrial volume index (r=0.331, p=0.001), the ratio between early mitral inflow velocity and flow propagation velocity (r= 0.326, p=0.001), and the ratio between early mitral inflow velocity and mitral annular early diastolic velocity (E/Em) (r= 0.314, p=0.001). Non-dipper BP, MBPS, and E/Em pattern were found to be independently associated with increased hospital admissions. Conclusion MBPS is associated with diastolic dysfunction and may be a sensitive predictor of hospital admission in patients with systolic heart failure.

Registro Nacional do Controle da Hipertensão Arterial Avaliado pela Medida de Consultório e Residencial no Brasil: Registro LHAR / National Registry of Hypertension Control Evaluated by Office and Home Measurements: The LHAR National Registry

Resumo Fundamento Sabe-se que em torno de 30% dos pacientes apresentam valores de pressão arterial (PA) mais elevados quando examinados no consultório do que em suas residências. No mundo, admite-se que apenas 35% dos hipertensos já tratados tenham alcançado meta pressórica. Objetivo Fornecer dados epidemiológicos sobre o controle da PA nos consultórios, em uma amostra de cardiologistas brasileiros, avaliado pela medida de consultório e monitorização residencial da pressão arterial (MRPA). Métodos Análise transversal. Observou-se pacientes com diagnóstico de hipertensão arterial, em tratamento anti-hipertensivo, podendo ou não estar com a PA controlada. A PA foi verificada no consultório por profissional médico, e no domicílio através da MRPA. A associação entre variáveis categóricas se deu por meio do teste do qui-quadrado (p < 0,05). Resultados Foram incluídos 2.540 pacientes, com idade média 59,7 ± 15,2 anos. A maioria dos pacientes eram mulheres (62%; n = 1.575). O estudo mostrou uma prevalência de 15% (n = 382) de hipertensão do avental branco não controlada, e 10% (n = 253) de hipertensão mascarada não controlada. A taxa de controle da PA no consultório foi 56,3%, e no domicílio, de 61%; 46,4% dos pacientes tiveram PA controlada no consultório e fora dele. Observou-se maior controle no sexo feminino e na faixa etária 49-61 anos. Observando o controle domiciliar com o novo ponto de corte das Diretrizes Brasileiras de Hipertensão Arterial de 2020, a taxa de controle foi de 42,4%. Conclusão O controle pressórico nos consultórios em uma amostra de cardiologistas brasileiros foi de 56,3%; 61% quando a PA foi obtida no domicílio, e 46,4% quando o controle foi observado tanto no consultório como no domicílio.

Abstract Background It is known that around 30% of patients have higher blood pressure (BP) values when examined at the office than at home. Worldwide, only 35% of patients with hypertension undergoing treatment have reached their BP targets. Objective To provide epidemiological data on BP control in the offices of a sample of Brazilian cardiologists, considering office and home BP measurement. Methods This is a cross-sectional analysis of patients with a hypertension diagnosis and undergoing antihypertensive treatment, with controlled BP or not. BP was assayed in the office by a medical professional and at home using home BP monitoring (HBPM). The association between categorical variables was verified using the chi-square test (p<0.05). Results The study included 2540 patients, with a mean age of 59.7 ± 15.2 years. Most patients were women (62%; n=1575). Prevalence rates of 15% (n=382) for uncontrolled white coat hypertension and 10% (n=253) for uncontrolled masked hypertension were observed. The rate of BP control in the office was 56.3% and at home, 61%. Meanwhile, 46.4% of the patients had controlled BP in and outside of the office. Greater control was observed in women and in the 49-61 years age group. Considering the new DBHA 2020 threshold for home BP control, the control rate was 42.4%. Conclusion BP control in the offices of a sample of Brazilian cardiologists was 56.3%; this rate was 61% when BP was measured at home and 46.4% when considering both the office and home.

A Variação Anormal da Pressão Arterial Circadiana está Associada aos Escores SYNTAX em Pacientes Hospitalizados com Síndrome Coronariana Aguda / Abnormal Circadian Blood Pressure Variation is Associated with SYNTAX Scores in Hospitalized Patients with Acute Coronary Syndrome

Resumo Fundamento Menor redução da pressão arterial (PA) noturna, conhecida como hipertensão não-dipper, é um forte preditor de morbimortalidade cardiovascular. Objetivos Este estudo visou investigar a relação entre a hipertensão não-dipper e a gravidade e complexidade da doença arterial coronariana usando o escore SYNTAX em pacientes hospitalizados com síndrome coronariana aguda. Métodos Foram selecionados 306 pacientes consecutivos com síndrome coronariana aguda. Pacientes clinicamente estáveis internados na unidade de terapia intensiva intermediária pelo menos 24 horas após a angiografia e/ou revascularização bem sucedida. Após os critérios de exclusão, foram incluídos 141 pacientes (34 mulheres e 107 homens; idade média 61 ± 11 anos). A hipertensão não-dipper foi definida como uma queda de 0% a 10% na PA sistólica média durante a noite em comparação com o dia, medida em intervalos de 1 hora, usando o mesmo dispositivo automático de medição de PA em monitores de beira de leito (Vismo PVM-2701; Nihon Kohden Corp., Tóquio, Japão). O escore SYNTAX foi calculado com uma calculadora online. Os preditores independentes do escore SYNTAX foram avaliados por meio de análise de regressão logística multivariada. P < 0,05 foi considerado estatisticamente significativo. Resultados Os pacientes com hipertensão não-dipper apresentaram escore SYNTAX maior do que os pacientes com hipertensão dipper (11,12 ± 6,41 versus 6,74 ± 6,45, p < 0,0001). Em um modelo de regressão logística multivariável, o status de hipertensão não dipper (odds ratio: 5,159; intervalo de confiança de 95%: 2,246 a 11,852, p < 0,001), sexo (p = 0,012) e colesterol de lipoproteína de baixa densidade (p = 0,008) emergiram como preditores independentes de alto escore SYNTAX. Conclusões Os resultados do nosso estudo fornecem um possível mecanismo adicional ligando o perfil anormal da PA circadiana à gravidade e à complexidade da doença arterial coronariana em pacientes com síndrome coronariana aguda.

Abstract Background Blunted nocturnal blood pressure (BP) reduction, referred to as non-dipper hypertension, is a strong predictor of cardiovascular morbidity and mortality. Objectives This study aimed to investigate the relationship between non-dipper hypertension and the severity and complexity of coronary artery disease using SYNTAX score in hospitalized patients with acute coronary syndrome. Methods A total of 306 consecutive patients with acute coronary syndrome were screened. Patients who were clinically stable and admitted to the intermediate intensive care unit at least 24 hours after angiography and/or successful revascularization. After the exclusion criteria, 141 patients (34 female and 107 male; mean age 61 ± 11 years) were included. Non-dipper hypertension has been defined as a 0% to 10% decrease in average systolic BP at nighttime compared to daytime, measured at hourly intervals using the same automatic BP measuring device on bedside monitors (Vismo PVM-2701; Nihon Kohden Corp., Tokyo, Japan). SYNTAX score was calculated with an online calculator. The independent predictors of SYNTAX score were assessed using multivariable logistic regression analysis. P < 0.05 was considered statistically significant. Results The patients with non-dipper hypertension had higher SYNTAX score than the patients with dipper hypertension (11.12 ± 6.41 versus 6.74 ± 6.45, p < 0.0001). In a multivariable logistic regression model, non-dipper hypertension status (odds ratio: 5.159; 95% confidence interval: 2.246 to 11.852, p < 0.001), sex (p = 0.012) and low-density lipoprotein cholesterol (p = 0.008) emerged as independent predictors of high SYNTAX score. Conclusions The results of our study provide a possible additional mechanism linking abnormal circadian BP profile with coronary artery disease severity and complexity in patients with acute coronary syndrome.

Hipertensión nocturna y eventos cardiovasculares en un hospital de la ciudad de Buenos Aires / Nocturnal Hypertension and Cardiovascular Events at a Buenos Aires City Hospital

RESUMEN Introducción: Nuestro objetivo fue determinar si la hipertensión arterial nocturna (HTAN) se asocia a eventos cardiovasculares o mortalidad en el seguimiento. Material y métodos: Estudio de cohorte retrospectiva que incluyó pacientes adultos que se realizaron una presurometría ambulatoria en un hospital de la ciudad de Buenos Aires, incorporados a un registro propio entre marzo de 2017 y julio de 2020, con seguimiento de hasta 36 meses de la presurometría índice. Se realizaron análisis uni y multivariados para identificar factores asociados. Resultados: De 522 sujetos, se incluyeron 494 en el análisis final. El 48% eran de sexo masculino y la edad promedio fue de 58,9 años. El 62% (n = 308) presentó HTAN. Se halló una mayor incidencia del punto final compuesto cardiovascular en este grupo en comparación con quienes no la presentaban, 10,4% vs 3,8% (p = 0,013). El análisis final por regresión de Cox multivariada demostró que la HTAN fue un predictor independiente de eventos cardiovasculares (HR = 3,9; IC 95% 1,56-9,81; p = 0,001), incluso independientemente de la HTA diurna y de los diferentes patrones circadianos de presión. Conclusión: En una cohorte contemporánea y de la ciudad de Buenos Aires, el patrón de HTAN se asoció con la aparición de desenlaces cardiovasculares. En base a estos hallazgos, se deben implementar medidas para incrementar su diagnóstico en nuestro medio.

ABSTRACT Background: Nocturnal Hypertension (NHT) has an impact on cardiovascular morbidity and mortality. Our aim was to evaluate the association between NHT and cardiovascular events. Methods: We carried out a retrospective cohort study including adults which had an ambulatory blood pressure monitoring test between March 2017 and July 2020 at a hospital in Buenos Aires City Argentina, with up to 36 months follow-up. Univariate and multivariate analyzes were performed to identify associated factors. Results: Four hundred and ninety four patients were included in the final analysis, 48% male, average age 58.9 years. Sixty two percent (n=308) presented NHT. A higher incidence of the cardiovascular composite endpoint was found in this group compared to those who did not present it, 10.4% vs 3.8% (p=0.013). In the final multivariate Cox regression analysis NHT was an independent predictor of cardiovascular events (HR=3.9; 95% CI 1.56-9.81; p=0.001), even independently of daytime HTN and the different circadian patterns of pressure. Conclusions: In this contemporary cohort from Buenos Aires, NHT was related to cardiovascular events incidence. Different measures should be taken to increase NHT awareness and diagnosis.

ABSTRACT Objective. To evaluate the effectiveness of a standardized and simplified protocol based on the technical pillars of the HEARTS Initiative for the control of hypertensive patients in the Cardiovascular Health Program at the first level of care in Chile. Methods. Longitudinal observational study (historical cohort) in two family health centers at the first level of care in Santiago. The control of blood pressure in hypertensive adults using a standardized and simplified protocol was compared to the usual protocol based on national guidelines. Innovations in the standardized protocol included changes in how the health team is coordinated, initiation of pharmacological treatment immediately after confirmed diagnosis, standardized pharmacological treatment with a combination of at least two or three antihypertensive drugs taken daily in a single tablet. Follow-up was conducted after one year to assess the percentage of adherence to treatment and achievement of blood pressure control targets (< 140/90 mmHg). Results. A total of 1490 patients were evaluated: 562 who followed the standardized and simplified protocol, and 928 who were treated with the usual protocol (family health centers: 650; family health centers: 278). After one year, patients in the standardized and simplified protocol group had a higher proportion of adherence to blood pressure control targets (65% versus 37% and 41%, p<0.001) and higher adherence to treatment compared to those following the usual protocol (71% versus 18% and 23%, p<0.001). Conclusions. The results show that the standardized and simplified protocol is more effective than the usual protocol in controlling arterial hypertension in patients undergoing treatment at the first level of care in Chile. Its implementation at the national level could contribute to a decrease in major cardiovascular events.

Day and night blood pressure variability among older persons in South­Western Nigeria

Background: Hypertension is the largest contributor to the global burden of disease. Emerging risk factors for cardiovascular disease include blood pressure variability (BPV), but evidence on BPV is lacking among older Nigerians. We reported BPV in a cohort of older persons at the University College Hospital (UCH), Ibadan. Methods: We conducted a retrospective cohort study of respondents aged >50 years within the Ibadan Ambulatory Blood Pressure Registry at the UCH, Ibadan, Nigeria. Socio-demographic characteristics, lifestyle habits and anthropometric measurements were obtained. Results: Among 639 respondents, 332 (52.0%) were female. The blood pressure (BP) variables were strongly associated with age. Compared with younger age groups, mean diastolic BP (DBP) was less at an older age, whereas mean pulse pressure was greater. During the wake-up and sleep periods, mean DBP and mean arterial BP were less with each increasing age category, whereas mean pulse pressure was larger with each increasing age category. BP dipping, systolic, diastolic and mean arterial BP decreased with age. Overall, timed BPV increased significantly with increasing age. The prevalence of white­coat hypertension was greater among older participants than younger participants. Most respondents in the 50­59 years' age group were non-dippers (55.8%), whereas 33.7% of older respondents were reverse-dippers. Conclusion: Older persons experienced a greater abnormal circadian blood variation and greater BPV than younger people. In Nigeria, follow­up data are needed to determine the prognostic significance of these data in this population

Effects of an internet-based blood pressure monitoring and management platform on blood pressure control in a prehypertensive population: an intervention study / 中华健康管理学杂志

Objective:To explore the intervention effects of an Internet-based blood pressure monitoring and management platform in a prehypertensive population.Methods:One hundred and fifty-eight prehypertensive patients who were examined at the Third Xiangya Hospital in Changsha, China, from August to December 2019 were randomly divided into either the experimental or control groups using the random number table method. The experimental group utilized an Internet-based blood pressure monitoring and management platform, whereas the control group utilized regular telephone and SMS health management routines. The intervention duration was 12 months for both groups. Data were analyzed using descriptive analysis, t-tests, chi-square tests, χ 2 tests, and rank-sum tests. Results:Post intervention systolic blood pressure (124.79±9.71 mmHg) (1 mmHg=0.133 kPa) and diastolic blood pressure measurements (77.41±8.21 mmHg) of the participants in the experimental group were significantly lower than those before the intervention (128.29±5.10 mmHg and 79.99±6.01 mmHg, respectively), and significantly lower than those of the control group′s measurements after the intervention (130.00±7.78 mmHg and 80.33±7.90 mmHg, respectively) (all P<0.05). The blood pressure goal attainment rate was significantly higher in the experimental group (23.08%) than that of the control group (8.75%), with statistically significant differences within the experimental group before and after intervention, as well as between the groups post intervention ( P<0.05). Positive lifestyle changes, such as prehypertension knowledge score, active restriction and control of salt and oil intake, reduction of smoking, and exercising weekly, were significantly higher than those in the control group before the intervention (all P<0.05). Conclusion:The use of an Internet-based blood pressure monitoring and management platform can effectively help patients with prehypertension control their blood pressure levels, improve their knowledge about the condition, and improve their lifestyle choices.

Invasive arterial blood pressure monitoring improves the prognosis of patients with sepsis / 中华急诊医学杂志

Objective:To evaluate the effect of invasive arterial blood pressure (IBP) monitoring on the prognosis of patients with sepsis.Methods:Patients with sepsis from the MIMIC-Ⅳ database were collected and divided into IBP and non-invasive blood pressure monitoring (NIBP) groups according to whether IBP monitoring was performed. Baseline variables that were considered clinically relevant or showed a univariate relationship with the outcome were entered into a multivariate logistic regression model as covariates.Propensity score matching(PSM) and inverse probability of treatment weighing(IPTW) were used to adjust confounders to ensure the robustness of findings.Subgroup analysis were conducted to evaluate the effect of differences in IBP onset and duration on outcome.Results:The 28-day mortality is lower in IBP group compared with NIBP group( OR=0.54, 95% CI 0.46-0.62, P<0.001), the conclusion maintain robust after PSM and IPTW.Then we conducted a series of logistic regression regarding to different initial IBP time(<24 h,24 h-48 h,>48 h) and the initial IBP time within 24 h showed the same results compared to primary outcoms( OR=0.42, 95% CI: 0.36-0.49, P<0.001). IBP duration varied (≤1day, ≤2days, ≤3days, ≤4days, >4days) all showed a statistically significant association with decreased 28-day mortality in the IBP group. Conclusions:IBP is associated with decreased 28-day mortality in patients with sepsis, and the optimal time of IBP is within 24 hours.

Control rate of ambulatory blood pressure and influencing factors among hypertensive patients in Shanghai Fengpu community / 中华全科医师杂志

Objective:To analyze the control status of ambulatory blood (BP) pressure and influencing factors among hypertensive patients in Shanghai Fengpu community.Methods:From April 2020 to February 2022, 318 hypertensive patients in Shanghai Fengpu community were enrolled in the study. The basic information and thropometric indicators of patients, course of hypertension, the medication, complications, life habits, and biochemical indicators as well as the ambulatory BP monitoring (ABPM) data were collected. Multivariate analysis was used to evaluate the risk factors for lack of 24-hour BP control.Results:Among 318 patients, 63 cases (19.8%) had an average 24-hour BP controlled; the control rate of daytime BP and nighttime BP was 23.3% (74 cases) and 15.7% (50 cases), respectively. The proportion of combined medication in the control group and non-control group was 46.0% (29/63) and 51.8% (132/255), respectively (χ 2=0.66, P=0.415). There were significant differences in gender, proportion of patients with hypertension>10 years, the office blood pressure control rate, the abnormal diastolic circadian rhythm, abdominal obesity, the level of fasting blood glucose, diabetes, physical activity levels, and smoking and drinking (all P<0.05) between the control group and non-control group. Multivariate analyses showed that male gender ( OR=2.00, 95 %CI:1.07-3.76) and abdominal obesity ( OR=2.04, 95 %CI:1.10-3.76) were risk factors for uncontrolled ambulatory BP. Conclusions:The control rate of ambulatory BP in patients with hypertension is relatively low in Shanghai Fengpu community. The ABPM should be enhanced and the management for hypertensive patients with abdominal obesity and lack of physical activity should be strengthened in the community.

Hipertensos Tratados e Avaliados por Telemonitoramento Residencial da Pressão Arterial. Estudo TeleMRPA / Treated Hypertensive Patients Assessed by Home Blood Pressure Telemonitoring. TeleMRPA Study

Resumo Fundamento: Hipertensos tratados avaliados apenas com a medida casual da pressão arterial (PA) podem estar sujeitos a decisões equivocadas. Objetivos: Avaliar o comportamento da PA pela medida casual e residencial (MRPA), o comportamento das classes de anti-hipertensivos e as prevalências de hipertensão do avental branco (HABNC) e mascarada não-controladas (HMNC). Métodos: Estudo transversal que avaliou pacientes pela plataforma TeleMRPA entre 2017 e 2019. Foram excluídos aqueles sem medicamentos, com 3 ou mais, em uso de espironolactona e alfa-2 agonistas. As variáveis analisadas foram: idade, sexo, índice de massa corporal (IMC), número de medidas válidas da PA, médias da PA sistólica (PAS) e diastólica (PAD) pela medida casual e MRPA, e as classes de anti-hipertensivos. Utilizados os testes t pareado e não pareado e qui-quadrado. Adotado nível de significância de 5%. Resultados: Selecionados 22.446 pacientes, dos quais 6.731 preencheram os critérios, sendo 61,3% do sexo feminino, com idade média de 57,8 (±12,6) anos e IMC médio de 29,0 (±5,1) kg/m2. Os valores médios de PAS e PAD foram 6,6 mmHg (p<0,001) e 4,4 mmHg (p<0,001) maiores na medida casual que na MRPA. As taxas de controle da PA foram de 57,0% pela medida casual e 61,3% pela MRPA (p<0,001), com prevalência de HABNC e HMNC de 15,4% e 11,1%, respectivamente. O bloqueio do sistema renina-angiotensina-aldosterona ocorreu em 74,6% das vezes e 54,8% estavam em monoterapia. Conclusões: O uso da MRPA deve ser considerado no acompanhamento de hipertensos tratados em virtude das elevadas prevalências de HABNC e HMNC. Os anti-hipertensivos tiveram comportamentos distintos nas medidas domiciliares. (Arq Bras Cardiol. 2021; [online].ahead print, PP.0-0)

Abstract Background: Hypertensive patients undergoing treatment and assessed only by casual blood pressure (BP) measurement may be subject to mistaken decisions. Objective: To assess BP behavior by measuring its levels at the office (casual) and at home (HBPM), the behavior of different classes of antihypertensive drugs, and the prevalence of uncontrolled white-coat hypertension (UCWCH) and uncontrolled masked hypertension (UCMH). Methods: Cross-sectional study assessing patients who underwent BP monitoring in the TeleMRPA platform between 2017 and 2019. The exclusion criteria were: use of no antihypertensive drug; combined use of 3 or more antihypertensive drugs; and use of spironolactone and alpha-2 agonist. The variables analyzed were: age, sex, body mass index (BMI), number of valid BP measurements, means of systolic and diastolic blood pressure (SBP and DBP, respectively) obtained from HBPM and casual measurement, and the classes of antihypertensive drugs. Paired and unpaired t tests, as well as chi-square test, were used. The 5% significance level was adopted. Results: This study selected 22 446 patients, 6731 of whom met the inclusion criteria [61.3%, female sex; mean age, 57.8 (±12.6) years; mean BMI, 29.0 (±5.1) kg/m2]. Mean SBP and DBP were 6.6 mm Hg (p<0.001) and 4.4 mm Hg (p<0.001) higher in casual measurement than in HBPM. The rates of BP control were 57.0% in casual measurement and 61.3% in HBPM (p<0.001), and the prevalence of UCWCH and UCMH was 15.4% and 11.1%, respectively. Renin-angiotensin-aldosterone system blockade was observed in 74.6% of the patients, and 54.8% were on single-drug therapy. Conclusions: HBPM should be considered for the follow-up of treated hypertensive patients because of the high prevalence of UCWCH and UCMH. Antihypertensive drugs behaved differently in HBPM.

Evaluation of blood pressure through home monitoring in brazilian primary care: a feasibility study / Avaliação da pressão arterial através da monitorização residencial na atenção básica brasileira: um estudo de viabilidade

Abstract Blood pressure measurements taken in a clinical setting are subject to errors, therefore there are advantages to monitoring blood pressure at home, especially in in patients diagnosed with hypertension. The study describes the feasibility of home monitoring to assess blood pressure in primary care and compares blood pressure measured at home and during a medical consultation. This cross-sectional study was carried out with patients whose used home blood pressure in the morning and evening, thrice for seven consecutive day sat home. Participants included patients older than 18 years with suspected whitecoat hypertension, taking antihypertensives, or those intolerant of ambulatory blood pressure monitoring, and excluded patients who did not follow the protocol, suffered from an irregular heart rate, and pregnant women. Of the 134 patients who participated in the study, 63.3% had altered blood pressure when measured at health facilities and 48% had higher blood pressure at home. The mean difference between the methods was 10.1 mmHg for systolic and 4.3 mmHg for diastolic. The prevalence of whitecoat hypertension was 19.4%. Blood pressure monitoring at home is a practicable strategy in the Brazilian healthcare system.

Doença de cushing e hipertensão arterial: relato de caso / Cushing disease and hypertension: a case report

Caso clínico de VNS, 23 anos, sexo feminino, branca, solteira, estudante, natural e procedente de São Paulo- SP com queixa de "pressão alta" há 4 anos. A paciente foi encaminhada para consulta ambulatorial após ter sido atendida em pronto-socorro (PS) com cefaleia, tonturas e pressão arterial (PA) 210x110 mm Hg e medicada com losartana 50 mg a cada 12 horas e hidroclorotiazida 25 mg ao dia. Na avaliação ambulatorial relatava episódios prévios de cefaleia holocraniana de forte intensidade, latejante, de início gradual há 4 anos com piora há 2 anos, que a levava ao pronto-socorro (PS) com muita frequência. Além disso, referia aumento de peso e fraqueza generalizada. Ao exame físico apresentava-se com níveis elevados da PA 160x100 mm Hg em uso das medicações prescritas no PS, obesidade grau III (IMC 41), adiposidade localizada (giba), acantose nigricans e estrias violáceas abdominais. Foi diagnosticada a doença de Cushing associada à hipertensão arterial não controlada, realizados ajustes dos agentes anti-hipertensivos (associado anlodipino 5 mg a cada 12 horas) e solicitados exames laboratoriais. A monitorização ambulatorial da PA (MAPA) de 24 horas caracterizou a hipertensão resistente, as dosagens de cortisol (cortisol salivar = 8h:172; após 23h:280, supressão com dexametasona =<2,5) e a ressonância nuclear magnética evidenciou um macroadenoma da hipófise confirmando o diagnóstico da doença de Cushing com base nos achados do exame físico, laboratorial e de imagem. A paciente foi tratada clinicamente com cetoconazol via oral sem sucesso e após isso submetida a ressecção transesfenoidal do macroadenoma de hipófise. Após o tratamento cirúrgico, houve perda de peso e resolução da hipertensão confirmada pelas medidas ambulatoriais de consultório e pela MAPA.

Clinical case of VNS, 23 years old, female, white, single, student, born and living in São Paulo-SP, complaining of "high blood pressure" 4 years ago. The patient was referred to an outpatient clinic after being seen in the emergency room (ER) with headache, dizziness and blood pressure (BP) 210x110 mm Hg and medicated with losartan 50 mg every 12 hours and hydrochlorothiazide 25 mg daily. In the outpatient evaluation, she reported previous episodes of severe, throbbing holocranial headache, which started gradually over 4 years and worsened over 2 years ago, which took her to the ER very often. In addition, she reported weight gain and generalized weakness. On physical examination, he presented with high BP levels 160x100 mm Hg using the medications prescribed in ER, obesity grade III (BMI 41), localized adiposity (gib), acanthosis nigricans and abdominal violet streaks. Cushing's syndrome was diagnosed associated with uncontrolled arterial hypertension, adjustments were made to antihypertensive agents (associated with amlodipine 5 mg every 12 hours) and laboratory tests were requested. 24-hour ambulatory BP monitoring (ABPM) characterized resistant hypertension, cortisol levels (salivary cortisol = 8:00 am: 172; after 11:00 pm: 280, dexamethasone suppression = <2.5) and magnetic resonance imaging revealed a macroadenoma of the pituitary gland confirming the diagnosis of Cushing's disease based on the findings of the physical, laboratory and imaging exam. The patient was clinically treated with oral ketoconazole and underwent transphenoid resection of the pituitary macroadenoma. After the surgery the patient was no longer hipertensive, without use of antihypertensive medications, outpatient office measurements were normal, as were measurements outside the office by ABPM
