                                                                        RESUMOObjetivo:  analisar  a  relação  existente  entre  os  parâmetros  de  avaliação  da  monitorização  ambulatorial de pressão arterial (pressão arterial, variabilidade, pressão de pulso, carga e padrão)  e o índice ambulatorial de rigidez arterial, de um hospital de quarto nível na cidade de Caracas,  Venezuela. Materiais e Métodos: realizou-se um estudo observacional retrospectivo, com uma  amostra significativa de 179 pacientes registrados na base dados de monitorização ambulatorial de  pressão arterial, na consulta cardiometabólica de um hospital, no período compreendido entre junho  a dezembro de 2014. Resultados: analisaram-se as monitorizações ambulatoriais de pressão arterial  de 179 pacientes em 24 horas, com idade média de 55 ± 16 anos, dos quais o 36,3 % era de sexo  masculino e o 87,0 % feminino, com um índice ambulatorial de rigidez arterial médio de 0,43 ± 0,17 e se utilizou a correlação de Pearson, com a pressão de pulso r = 0,50 p <0,001, com a idade r =  0,42 p <0,001, a pressão arterial sistólica r = 0,24 p = 0,001, a carga r = 0,20 p = 0,007. Conclusão: encontrou-se correlação positiva entre o índice ambulatorial de rigidez arterial e os parâmetros  de avaliação do índice ambulatorial de rigidez arterial, evidenciando que a rigidez ambulatorial  arterial é uma medida fácil de obter, que tem boa relação com fatores de risco conhecidos e pode ser  contemplada como parâmetro de controle e seguimento cardiovascular.PALAVRAS-CHAVE: monitorização ambulatorial, pressão arterial, rigidez arterial.Relación entre parámetros del monitoreo ambulatorio de presión arterial y el índice de rigidez arterial ambulatorio                                                                        RESUMENObjetivo: analizar la relación existente entre los parámetros de evaluación del monitoreo ambulatorio  de presión arterial (presión arterial, variabilidad, presión de pulso, carga y patrón) y el índice de rigidez  arterial ambulatorio, de un hospital de cuarto nivel en la ciudad de Caracas, Venezuela.

Materials and Methods: a retrospective observational study was performed, with a significant sample of 179  patients registered in the database of blood pressure monitoring, in the cardio metabolic consultation  unit of a hospital, in the period between June and December of 2014. Results: the blood pressure  monitoring of 179 patients were analyzed in 24 hours, with an average age of 55 ± 16 years , from  which 36.3% were male and 87,0% female, with an average of arterial stiffness index of 0,43 ±  0,17  and the Pearson’s correlations was used, with pulse pressure r = 0,50 p <0,001, with the age  r = 0,42  p <0,001, the systolic blood pressure  r = 0,24 p = 0,001, the load r = 0,20 p = 0,007. Conclusion: a positive correlation was found between the arterial stiffness index and the parameters of evaluation  of ambulatory arterial stiffness index, evidencing that the ambulatory arterial stiffness is an easy  measure to obtain, that it has a good relation with known risk factors, and can be contemplated as a  parameter of control and cardiovascular monitoring.KEYWORDS: monitoring  ambulatory, arterial pressure, vascular stiffness.

Chronic kidney disease (CKD) affects approximately two million people (in a population of 20 million) in Romania. Hypertension is often associated with CKD and both (hypertension and CKD) are risk factors for cardiovascular (CV) events. Ambulatory blood pressure monitoring (ABPM) is increasingly used all around the world for the diagnosis and monitoring of BP (blood pressure) because it is proven that the ABPM is superior to office BP measurements in evaluating patients with hypertension, with or without CKD. Reduced nocturnal BP fall (non-dipping or reverse-dipping patterns) is associated with target organ damage, especially kidney disease and the proportion of non-dippers and reverse-dippers patients increases progressively with the reduction of glomerular filtration rate (GFR). Another ABPM parameter, ambulatory arterial stiffness index (AASI), is an index which was recently proposed for the evaluation of arterial stiffness (a better tool than PP). It has prognostic value for cardiac death and stroke and several studies have showed that is negatively related to eGFR and is positively related to albuminuria. Hyperbaric area index (HBI) might be considered a novel sensitive marker [independent of patterns of NBPC (nocturnal BP change)] for the reduction of kidney function. These facts suggest that ABPM offers multiple useful data with impact, not only in future CV and renal outcomes assessment, but also in the treatment and management of hypertensive patients with CKD.

Objective. To assess the relationship between arterial stiffness parameters in hypertensive patients with and without atherosclerotic lesions.Design and methods. We included 127 subjects who were divided into 3 groups: patients with hypertension (HTN) without atherosclerosis (n = 42); patients with HTN and subclinical atherosclerosis (SА) (n = 52) and control group which consisted of individuals without HTN, SA, or coronary artery disease (n = 33). All groups matched by age and gender. All subjects underwent following examinations: ultrasonography of extracranial segments of carotid arteries, 24-hour blood pressure monitoring with the assessment of arterial stiffness parameters.Results. In subjects with HTN compared to controls, pulse wave velocity in aorta (PWVao) was significantly higher (11,3 ± 1,5; 12,3 ± 1,8 vs 10,4 ± 1,3 m/s; p < 0,05), as well as pulse pressure (PP) (46,4 ± 9,8; 45,6 ± 10,6 vs 39,9 ± 6,5 mmHg; p < 0,05), central pulse pressure (PPао) (35,5 ± 8,5; 34,9 ± 8,5 vs 30,9 ± 5,4 mmHg; p < 0,05), and arterial stiffness index (ASI) (141 (127, 159); 139 (128,5, 160,5) vs 126 (118, 138) mmHg; p < 0,05). In subjects with HTN and SA, PWVao was significantly higher compared to other groups (p < 0,05). No significant difference in augmentation index was found (–32,5 (–45, –12); –22 (–36, –12); –37 (–50, –17); p = 0,25). Аmbulatory arterial stiffness index was higher in controls (0,5 ± 0,2) compared to HTN group (0,4 ± 0,2; p = 0,05), while HTN and SA group did not differ significantly (0,5 ± 0,2; p = 0,3). PWVao above 11,15 m/s is associated with 4,3 (2,3–8,2) times higher rate of atherosclerosis plaque detection.Conclusions. In HTN patients, arterial stiffness is changed compared to healthy individuals. PWVao above 11,15 m/s is associated with 4,3 (2,3–8,2) times higher rate of atherosclerosis plaque detection. In patients with HTN and SA arterial stiffness is higher, which might have additional predictive value in risk stratification.

To examine the baseline associations of retinal vessel morphometry with blood pressure (BP) and arterial stiffness in United Kingdom Biobank. The United Kingdom Biobank included 68 550 participants aged 40 to 69 years who underwent nonmydriatic retinal imaging, BP, and arterial stiffness index assessment. A fully automated image analysis program (QUARTZ [Quantitative Analysis of Retinal Vessel Topology and Size]) provided measures of retinal vessel diameter and tortuosity. The associations between retinal vessel morphology and cardiovascular disease risk factors/outcomes were examined using multilevel linear regression to provide absolute differences in vessel diameter and percentage differences in tortuosity (allowing within person clustering), adjusted for age, sex, ethnicity, clinic, body mass index, smoking, and deprivation index. Greater arteriolar tortuosity was associated with higher systolic BP (relative increase, 1.2%; 95% CI, 0.9; 1.4% per 10 mmHg), higher mean arterial pressure, 1.3%; 0.9, 1.7% per 10 mmHg, and higher pulse pressure (PP, 1.8%; 1.4; 2.2% per 10 mmHg). Narrower arterioles were associated with higher systolic BP (−0.9 µm; −0.94, −0.87 µm per 10 mmHg), mean arterial pressure (−1.5 µm; −1.5, −1.5 µm per 10 mmHg), PP (−0.7 µm; −0.8, −0.7 µm per 10 mmHg), and arterial stiffness index (−0.12 µm; −0.14, −0.09 µm per ms/m 2 ). Associations were in the same direction but marginally weaker for venular tortuosity and diameter. This study assessing the retinal microvasculature at scale has shown clear associations between retinal vessel morphometry, BP, and arterial stiffness index. These observations further our understanding of the preclinical disease processes and interplay between microvascular and macrovascular disease.
