BACKGROUND The presence of asymptomatic left ventricular diastolic dysfunction (LVDD) in hypertensive patients can be associated with the development of cardiac events. The increase in sympathetic activity may be 1 of the mechanisms that predisposes to this outcome. In this study, we analyzed 2 hypotheses: (i) whether sympathetic activity is higher in the presence of LVDD, independent of blood pressure control and (ii) whether different classes of LVDD have a different effect on sympathetic activity. METHODS After analyzing left ventricular function using echo Doppler cardiography, 45 hypertensive patients receiving treatment were allocated into 3 groups: normal function (LV-NF, n = 15), impaired relaxation (LV-IR, n = 15), and pseudonormal or restrictive (LV-P/R, n = 15). An age-, sex-, and body mass index–matched control group of normotensive volunteers (N, n = 14) was included. Muscle sympathetic nerve activity (MSNA), heart rate, and systolic blood pressure variabilities and baroreflex sensitivity were evaluated while the patient was in a supine position. RESULTS Blood pressure and antihypertensive drug use were similar among the hypertensive groups. The LV-IR and LV-P/R groups had similar MSNA (33±1 and 32±1 bursts/min, respectively), which was significantly higher than that of the LV-NF and N groups (26±3 and 15±2 bursts/min, respectively). The LV-IR and LV-P/R groups had significantly higher LF-systolic blood pressure variability and significantly lower baroreflex sensitivity compared with the N group. CONCLUSIONS The presence of asymptomatic LVDD is associated with increased MSNA, independent of blood pressure control. The sympathetic hyperactivity associated with LVDD is similar in the different patterns of LVDD studied. [ABSTRACT FROM AUTHOR]

Background Methods Results Conclusions Antihypertensives (AHD) can influence cerebral autoregulation (CA) and attenuate hypertrophic concentric remodelling of arterioles. The aim of this study was to examine the associations between AHD, CA and structural and functional properties of cerebral arteries.In this observational, cross‐sectional study 115 volunteers were divided in group 1 (non‐hypertensive) [
n = 30]; group 2 (hypertensive with systolic blood pressure [SBP] < 140 and diastolic blood pressure [DBP] < 90 mmHg) [n = 54]; group 3 (hypertensive with SBP ≥ 140 or DBP ≥ 90 mmHg) [n = 31] and simultaneous measurements of systemic blood pressure (BP) and middle cerebral artery blood flow velocity (CBFV) were obtained from digital plethysmography and transcranial Doppler. Beat‐to‐beat, critical closing pressure (CrCP), resistance‐area product (RAP) and autoregulation index (ARI) values were extracted by linear regression analysis of instantaneous BP and CBFV waveforms using computerised analysis. Pulsatility index (PI) was calculated and CO2 reactivity was assessed by the breath‐holding test.Despite their higher RAP (1.7 [±0.7],p < 0.001) compared to groups 1 and 2, uncontrolled hypertensive using diuretics (p = 0.047) and α2‐agonists (p = 0.009) had significantly lower PI. Impaired CO2 reactivity was common between the two hypertensive groups (p = 0.008), however ARI, CrCP and CBFV did not differ between them and non‐hypertensive individuals and also did not correlate with any AHD used.Unlike the RAP, PI does not seem to reflect the real cerebrovascular resistence resulting from chronic arterial remodelling. Despite impaired CO2 reactivity, hypertensive have arterial tonus and CA comparable to non‐hypertensive. Experimental studies involving an untreated hypertensive control group are required to robustly make definitive conclusions about these questions. [ABSTRACT FROM AUTHOR]- Published

FUNDAMENTO: A doença renal crônica (DRC) caracteriza-se pela alta prevalência de aterosclerose. Uma vez que o estresse oxidativo e a disfunção endotelial são promotores da aterosclerose, é interessante verificar se as duas condições estão associadas em pacientes com DRC, ainda sem doença cardiovascular (DCV) clínica. OBJETIVO: Avaliar as relações entre o estresse oxidativo e a função endotelial em pacientes com DRC estágio 5, sem DCV. MÉTODOS: Foram estudados 22 pacientes com DRC, não-diabéticos, não-fumantes, sem DCV e tratados por hemodiálise; além de 22 indivíduos normais. Em todos os indivíduos foram avaliados a reatividade vascular, dependente e independente de endotélio (ultra-som de alta resolução da artéria braquial), e o estresse oxidativo (níveis plasmáticos de substâncias reativas ao ácido tiobarbitúrico - TBARS). RESULTADOS: A reatividade vascular dependente de endotélio (6,0 ± 4,25% vs. 11,3 ± 4,46%, p

Metodologia: Foram recrutados 48 voluntários de 20 a 40 anos de idade, onde 32 eram praticantes de vários níveis de corrida de rua, e 16 eram indivíduos aparentemente saudáveis e não praticantes regulares de atividade física nos últimos 6 meses. Avaliou-se a aptidão cardiorrespiratória e a velocidade máxima de corrida, pelo TCPE utilizando equipamento Metamáx 3B (Córtex), e protocolo de rampa em esteira. As medidas da PA central e periférica foram realizadas com a tonometria de aplanação (Sphygmocor), e calibrado utilizando o esfigmomanômetro oscilométrico (Omron, HEM 705). A velocidade de onda de pulso (VOP) carótida-femural foi mensurada utilizando o equipamento Complior (Artech Medical). Para análise estatística foi realizada a ANOVA de uma via considerando p

Made available in DSpace on 2015-03-04T18:57:50Z (GMT). No. of bitstreams: 1 tese part1.pdf: 16560182 bytes, checksum: b1b85ba9cf99cc97cd1daa82ff037abf (MD5) Previous issue date: 2013-05-10 This work presents an anatomically detailed arterial network model denoted by the acronym ADAN. The ADAN is a computational model of the human arterial system provided by an unprecedented anatomically detailed arterial network in cardiovascular research and carried out in order to simulate blood flow. This work is focused in two main points: (1) the complexity of the arterial network on top of which a one-dimensional mathematical model is used to perform blood flow simulations and (2) the boundary conditions of the one-dimensional model for which criteria and methodologies were developed to define and impose an effective blood flow distribution. With regard to topologial aspects, the anatomically-based arterial network comprises almost all arteries reported in the medical literature. In other words, this is the most complete human arterial model developed up to date. The ADAN model includes 2142 vessels from the vasculatures of the the head, trunk, limbs, abdominal organs, brain an heart. The develpment of this detailed arterial network needed the anatomical literature approved by the medical comunity and practices of anatomy by means of dissections of real specimens as well. The blood flow is modeled as flow of an incompressible fluid through compliant vessels. A one-dimensional approximation of blood flow is adopted in order to describe the flow rate, pressure and arterial lumen through the arterial tree in a distributed way. In order to deal with the boundaries conditions at the end points where the network was truncated, an innovative approach based on the Vascular Territories Theory was developed taking into account stringent physiological and anatomical criteria. Moreover, an algorithm for indetification of vascular territories resistances was also developed. Those two main points provided such a model of the arterial system able to simulate and to predict hemodynamics results at impossible placements through the existing models up to now. Besides, as result of an comprehensive research to find geometrical parameters of the model, the present work provides an wide morphometrical database of the human arterial system. The ADAN model can be used by medical doctors, physiologists, biomedical engineers and cardiovascular researchers as a computational hemodinamics laboratory of the entire human arterial tree. In addition, almost as a corollary, the ADAN model can also be explored for medical educational purposes. Este trabalho apresenta um modelo anatomicamente detalhado da rede arterial humana denominado pelo acrônimo ADAN. O ADAN é um modelo computacional do sistema arterial provido de um detalhamento anatômico sem precedentes na área da pesquisa em modelagem cardiovascular, desenvolvido para fins de simulações hemodinâmicas. O foco do trabalho está: (1) na complexidade da rede arterial sobre a qual se utiliza um modelo matemático unidimensional para simular o escoamento sanguíneo e (2) na modelagem das condições de contorno do problema de forma a prover critérios e metodologias para definir e impor uma dada distribuição efetiva do fluxo de sangue. Para tratar o aspecto da topologia, foi desenvolvida uma rede arterial com base na anatomia descritiva contendo a quase totalidade das artérias conhecidas e catalogadas na literatura médica, o que implica no modelo arterial humano mais completo já desenvolvido. Isto inclui 2.142 vasos que abrangem desde a vascularização da cabeça, tronco e membros até a rede arterial dos órgãos abdominais, cérebro e coronárias. No desenvolvimento desta rede arterial detalhada foram empregadas as referências anatômicas mais recomendadas e adotadas pela comunidade médica, assim como foram realizadas sessões práticas de estudos da anatomia humana em espécimes reais. O escoamento sanguíneo é modelado como o fluxo de um fluido incompressível em vasos complacentes. Uma aproximação de escoamento unidimensional é adotada, o que permite descrever de forma distribuída o fluxo, pressão e lumem arterial ao longo de toda a árvore. Para tratar o aspecto das condições de contorno em segmentos terminais onde a rede foi truncada, foi desenvolvida uma metodologia inovadora com base na Teoria dos Territórios Vasculares, levando em conta rigorosos critérios da anatomia vascular periférica e da fisiologia. Além disso, foi desenvolvido um procedimento algorítmico para a identificação dos parâmetros resistivos do modelo Windkessel para os leitos periféricos. Assim, estes dois aspectos citados conduziram a um modelo do sistema arterial capaz de simular, descrever e predizer resultados hemodinâmicos em regiões anatômicas antes impossíveis pelos modelos existentes. Além disso, como resultado de uma extensa pesquisa no processo de calibração geométrica do modelo, o trabalho disponibiliza uma ampla base de dados morfométricos da rede arterial humana, cujas informações, até o momento, somente eram encontradas em publicações dispersas tanto da literatura médica quanto da modelagem do sistema cardiovascular. O modelo ADAN da rede arterial humana pode ser utilizado com um laboratório de hemodinâmica computacional com um nível de abrangência tal que possa ser empregado por médicos, fisiologistas, engenheiros biomédicos ou outros profissionais envolvidos com a pesquisa cardiovascular. Além disso, quase como um corolário, o modelo ADAN presta-se, ainda, para finalidades didáticas na formação de recursos humanos em medicina, uma vez que possui características de um atlas tridimensional interativo e provido de modelo matemático-computacional da rede arterial humana.

Orientador: Heitor Moreno Junior Tese (doutorado) - Universidade Estadual de Campinas, Faculdade de Ciencias Medicas Resumo: Introdução Hipertensão resistente é definida como a pressão arterial que permanece acima da meta pressórica, apesar do uso de 3 classes de antihipertensivos sendo um deles um diurético. Recentes diretrizes da American Heart Association (AHA-2008) consideraram também hipertensos resistentes os pacientes que usam 4 ou mais classes e possuem suas pressões controladas. No entanto, é desconhecido se as repercussões cardíacas e vasculares nos pacientes hipertensos resistentes não controlados (HARNC) e controlados (HARC) são semelhantes e qual a influência do envelhecimento sobre esses subgrupos de hipertensos resistentes (HAR). Objetivo Comparar as repercussões cardíacas e vasculares nos HARNC e HARC e avaliar a influência do envelhecimento nesses subgrupos. Métodos Após a triagem e adesão rigorosa, noventa pacientes foram separados em HARNC (n=47) e HARC (n=43). Pressão arterial sistólica (PAS), pressão arterial diastólica (PAD), pressão de pulso (PP), velocidade de onda de pulso (VOP), índice de massa do ventrículo esquerdo (IMVE), índice de massa corpórea (IMC), concentração plasmática de aldosterona (CPA) e atividade renina plasmática (ARP) foram avaliados. Realizaram-se testes estatísticos paramétricos e não paramétricos e regressão linear multivariada (RLM) e univariada (RLU). Resultados A PAS, PAD, PP, VOP, IMVE, IMC e CPA foram maiores nos HARNC (PAS=170/150/204 mmHg; PAD=100/88/130 mmHg; PP=69/40/91 mmHg; VOP=10.9/8/15.3 m/s; IMVE=179±49.2 g/m2; IMC=32±2.1 Kg/m2 e CPA=24.4±3.2 ng/dL), comparados com os HARC (PAS=143/130/163 mmHg; PAD=90/70/116 mmHg; PP=54.5/30/75 mmHg; VOP=9.5/6.8/11.3 m/s; IMVE=140.3±30.1 g/m2; IMC=28.3±1.5 Kg/m2 e CPA=19.7±2.6 ng/dL)(p

Orientador: Heitor Moreno Junior Tese (doutorado) - Universidade Estadual de Campinas, Faculdade de Ciencias Medicas Resumo: Introdução: O diagnóstico de hipertensão arterial resistente requer cuidadosa avaliação da adesão ao tratamento prescrito. Objetivos: Analisar a adesão ao tratamento dos pacientes com hipertensão arterial de difícil controle, referenciados ao Ambulatório de Farmacologia Cardiovascular do Hospital das Clínicas da Universidade Estadual de Campinas, a fim de identificar os hipertensos resistentes ao tratamento farmacológico. Avaliar também os resultados clínicos e humanísticos durante o seguimento farmacoterapêutico. Método. Realizou-se um estudo prospectivo de 44 pacientes acompanhados por um período de 12 meses. Durante o seguimento farmacoterapêutico, utilizaram-se os seguintes instrumentos: Teste de Morisky et al. e contagem de comprimidos para análise da adesão ao tratamento; teste do conhecimento em relação à doença e ao tratamento anti-hipertensivo; análise da pressão arterial (PA) ambulatorial e através da Monitorização Ambulatorial da Pressão Arterial (MAPA); para qualidade de vida, utilizou-se o instrumento genérico como o SF-36 e instrumento específico (perfil de sintomas físicos); também utilizaram-se os facilitadores de cuidados à saúde (urgência hipertensiva e internação hospitalar). Resultados: Com relação à adesão ao tratamento pelo método contagem de comprimidos, 63,6% dos pacientes foram aderentes no início e, 95,4%, no final do estudo. Pelo Teste de Morisky et al., a adesão foi de 36,4%, no início e, 68,2%, no final. Os hipertensos apresentaram altos níveis de conhecimento em relação à doença e ao tratamento, porém não houve relação com o controle da pressão arterial.

- Abstract
Context: The outcomes related to cardiovascular risk (CVR) in patients with nonclassical form of congenital adrenal hyperplasia (NCAH) are unknown, especially those related to therapeutic options, including low doses of glucocorticoids (GCs) or oral contraceptive pills., Objectives: to analyze CVR by markers of atherosclerosis in females with nonclassical form according to therapeutic options., Design and Setting: a cross-sectional study at a tertiary center., Patients and Methods: Forty-seven females with NCAH (33.4 ± 10 years) were subdivided into: G1 (n = 28) treated with dexamethasone (0.14 ± 0.05 mg/m2/day); G2 (n = 19) with oral contraceptive pills; and G3 (30 matched controls). CVR was analyzed through serum lipids, HOMA-IR, inflammatory cytokines levels and quantitative image evaluations (pulse wave velocity-PWV, endothelial function by flow mediated dilatation-FMD, carotid intima media thickness-CIMT and visceral fat-VAT by abdominal tomography., Results: There were no statistically significant differences in BMI, HOMA-IR, HDL-cholesterol, or triglyceride levels among groups (p > 0.05). Serum interleukin-6 levels were higher in G1 than in G2 (p = 0.048), and interleukin-8 levels were higher in G1 than in G2/3 (p = 0.008). There were no statistically significant differences in VAT, PWV, FMD or CIMT among groups (p > 0.05). In multivariable regression analysis, there was no statistically significant association between glucocorticoid dose and evaluated outcomes., Conclusion: Adult females with NCAH did not show increased CVR using methodologies for detection of precocious atherosclerosis. Although patients receiving dexamethasone therapy had increased IL-6 and 8 levels, these data were not associated with radiological markers of atherosclerosis. Our cohort was composed of young adults and should be reevaluated in a long-term follow-up., (© The Author(s) 2024. Published by Oxford University Press on behalf of the Endocrine Society.)

- Abstract
Distances walked in walking tests are important functional markers, although they are not accepted as defining characteristics of Ineffective Peripheral Tissue Perfusion. The aims of this study were to verify the distances participants with and without this nursing diagnosis walked in the six-minute walk test and if these measures may be considered defining characteristics of this phenomenon. Participants with (group A; n=65) and without (group B; n=17) this nursing diagnosis were evaluated regarding physical examination, vascular function and functional capacity. Participants of group A seemed to have worse vascular function and functional capacity compared with those of group B. Pain-free travelled distance was predictive of the nursing diagnosis. These results are important for the refinement of this diagnosis. In conclusion, this study provides evidences that the distances walked in the six-minute walk test may be considered defining characteristics of Ineffective Peripheral Tissue Perfusion.

- Abstract
Background: Chronic kidney disease (CKD) is characterized by the high prevalence of atherosclerosis. Considering that endothelial dysfunction and oxidative stress are promoters of atherosclerosis, it is of interest to verify whether the two conditions are associated in CKD patients still free of clinical cardiovascular disease (CVD)., Objective: To evaluate the association between oxidative stress and endothelial function in end-stage CKD patients without clinically evident CVD., Methods: We studied 22 nondiabetic, nonsmoker CKD patients without clinical CVD treated by maintenance hemodialysis and 22 healthy controls. Endothelium- dependent and independent vascular reactivity and oxidative stress, as determined by the plasma levels of thiobarbituric acid-reactive substances--TBARS, were evaluated in all subjects., Results: Endothelium-dependent (6.0 +/- 4.25 vs. 11.3 +/- 4.46%, p<0.001) and endothelium-independent (11.9 +/- 7.68 vs. 19.1% +/- 6.43%, p<0.001) vascular reactivity were reduced, while TBARS (2.63 +/- 0.51 vs. 1.49 +/- 0.42 nmols/mL) was increased in CKD patients when compared to controls. TBARS levels were significantly related to endothelium-dependent vascular reactivity (r=-0.56, p<0.001) and to systolic blood pressure (r=-0.48, p=0.002)., Conclusion: Oxidative stress is increased in CKD patients free of CVD and is associated with endothelial dysfunction in patients and controls. The results suggest that oxidative stress and endothelial dysfunction may be involved in the increased susceptibility of CKD patients to CVD and cardiovascular complications.

- Abstract
Functional and structural modifications in large arteries play an important role in the pathogenesis of cardiovascular diseases. The diabetes mellitus besides arterial hypertension and ageing can induce these alterations in different arterial sites, and so leading to the development of atherosclerosis and its cardiovascular consequences. The main functional change of large arteries is an increase of stiffness, while the main structural modification is an increase of the intima-media thickness of carotid artery, and both changes have been recognized in both type 1 and type 2 diabetes. The mechanisms of these structural and functional arterial modifications in diabetes include insulin resistance, collagen increase due to inadequate enzymatic glycation, endothelial and autonomic dysfunction. The increase of arterial stiffness is an independent cardiovascular risk marker in diabetic patients, and the treatment of diabetes per se and even of associated dyslipidemia and arterial hypertension can favorably modify these arterial changes.
