RESUMO
BACKGROUND: Nocturnal hypertension (NH) is a potent cardiovascular risk factor described frequently in people with HIV (PWH). Isolated NH (INH) is less well reported in PWH because of the need for ambulatory blood pressure monitoring (ABPM) in office normotensive patients. We aim to document the prevalence of NH and INH and the clinical factors associated with these phenotypes. METHODS: Cross-sectional study from an HIV program in Argentina. Office and ABPM measurements, as well as clinical and laboratory exploration, were performed. We defined INH as NH with daytime normotension in patients with office normotension. RESULTS: We obtained ABPM in 66 PWH, 60% male, aged 44.7 (IQR 27-69) years; 87% receiving antiretroviral therapy, and 86.2% virologically suppressed. ABPM-based hypertension prevalence was 54.7% (95% CI: 42.5-66.3). The prevalence of NH was 48.5% (32/66), while the INH prevalence was 19.7% (95% CI: 11.7-30.9). No differences were found regarding sex, HIV viral load, CD4+ T lymphocytes count, or years of infection between normotensive and INH patients. Multiple linear regression model adjusted for sex and age determined that body mass index (ßâ =â 0.93, Pâ <â 0.01), plasma uric acid (ßâ =â 0.25, Pâ =â 0.04), plasma potassium (ßâ =â -10.1, Pâ =â 0.01), and high-sensitivity C-reactive protein (hs-CRP) (ßâ =â 0.78, Pâ =â 0.02) independently predicted nocturnal systolic blood pressure (BP) in PWH. In a multiple logistic regression model adjusted for age and sex, the presence of sedentariness, plasma potassium <4 mEq/L, BMI, and hs-CRP levels were predictors of INH. CONCLUSION: INH is highly prevalent in PWH. Metabolic and inflammatory markers predict nocturnal SBP in PWH.

OBJECTIVE: To describe the epidemiology of reclassification of prehypertensive and unclassified adolescents by 2022 American Heart Association pediatric ambulatory blood pressure monitoring (ABPM) guidelines, and to evaluate the association of the new diagnostic categories with left ventricular hypertrophy (LVH). STUDY DESIGN: A single-center, retrospective review of ABPM reports from adolescents 13-21 years old, from 2015 through 2022, was performed. Adolescents with prehypertension or unclassified by 2014 guidelines were reclassified by 2022 definitions. Logistic regression models evaluated the association of reclassification phenotypes with LVH. RESULTS: A majority of prehypertensive adolescents reclassified to hypertension (70%, n = 49/70). More than one-half (57%, n = 28/49) of the hypertension was isolated nocturnal hypertension, and 80% was systolic hypertension. Reclassification to hypertension was more common in males. The majority (55.6%) of unclassified adolescents were reclassified to normotension. No demographic or clinical variables were associated with reclassification categories. LVH was not associated with hypertension in the reclassified prehypertensive or unclassified groups. CONCLUSIONS: The 2022 ABPM guidelines clearly define blood pressure phenotypes. However, reclassification to hypertension was not associated with an increased odds of LVH. Because most prehypertensive adolescents reclassified as hypertensive by nighttime BPs alone, this study highlights the lowered threshold for nocturnal hypertension. Prospective studies in larger, well-defined cohorts are needed to describe better the predictive value of 2022 BP phenotypes for target organ damage.

Isolated nocturnal hypertension (INH) and masked nocturnal hypertension (MNH) increase cardiovascular risk. Their prevalence and characteristics are not clearly established and seem to differ among populations. We aimed to determine the prevalence and associated characteristics of INH and MNH in a tertiary hospital in the city of Buenos Aires. We included 958 hypertensive patients ≥ 18 years who underwent an ambulatory blood pressure monitoring (ABPM) between October and November 2022, as prescribed by their treating physician to diagnose or to assess hypertension control. INH was defined as nighttime BP ≥ 120 mmHg systolic or ≥70 diastolic in the presence of normal daytime BP (<135/85 mmHg regardless of office BP; MNH was defined as the presence of INH with office BP < 140/90 mmHg). Variables associated with INH and MNH were analyzed. The prevalences of INH and MNH were 15.7% (95% CI 13.5-18.2%) and 9.7 (95% CI 7.9-11.8%), respectively. Age, male sex, and ambulatory heart rate were positively associated with INH, whereas office BP, total cholesterol, and smoking habits showed a negative association. In turn, diabetes and nighttime heart rate were positively associated with MNH. In conclusion, INH and MNH are frequent entities, and determination of clinical characteristics such as those detected in this study is critical since this might contribute to a more appropriate use of resources.
RESUMO
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.
