ABSTRACT

SUMMARY OBJECTIVE: The objective of this study was to analyze the association between orthostatic changes in blood pressure and mortality in elderly cardiopath patients. METHODS: A cohort of 455 elderly cardiopath patients, monitored at a referral outpatient cardiology clinic in Pernambuco, Brazil, from October 2015 to July 2018. The exposure groups were formed according to their orthostatic changes in blood pressure following the requirements of the Brazilian Guidelines for Hypertension. RESULTS: Orthostatic hypotension was present in 46 patients (10.1%), 91 had orthostatic hypertension (20%), and 318 had no orthostatic alterations (69.9%). There were 52 deaths during follow-up. The results demonstrated that there was no statistically significant association between orthostatic hypotension and overall mortality (HR 1.30; 95%CI 0.53-3.14; p=0.567) nor between orthostatic hypertension and overall mortality (HR 0.95; 95%CI 0.65-1.39; p=0.34). Survival in relation to the exposure groups presented no statistically significant difference (p=0.504). CONCLUSION: There was a low frequency of orthostatic hypotension and a mild high frequency of orthostatic hypertension when compared with previous studies, and no association was observed with overall mortality or with the survival time of elderly patients with heart disease.

ABSTRACT

ABSTRACT In the environment of rapid social and economic development, the reform of medical informatization is constantly advancing, and the residents pay more and more attention to their own health status while improving their living standards. The traditional medical service system has some disadvantages in providing real-time, cross regional, long-term and easy-to-operate health services, which has become increasingly inadequate to meet the health needs of users. In order to solve the problem of difficulty in seeing a doctor caused by limited medical resources, and to carry out real-time health monitoring for a large number of groups suffering from chronic diseases and sub-health groups, this study conducted in-depth analysis and experimental exploration on the human remote mobile medical information collection method based on the Internet of things and intelligent algorithm. It established the information collection section by using KbaC clustering algorithm based on ant colony point system which, combined with a comparative study on the health indicators of related groups, has successfully proved that the Internet of things technology and intelligent algorithm for medical information collection and follow-up medical services are of certain positive significance, based on the Internet of things and other related technologies of human remote medical information collection system that can accurately and timely detect the patient's blood pressure, blood sugar and other health data, and then provide corresponding medical services.

ABSTRACT

Hypertension is a major problem of public health that endangers the health of the oldest old. However, the current guidelines for hypertension management do not uniformly diagnose hypertension among the oldest old, nor recommend a normal blood pressure range, which is not convictive enough to support the decision making to the prevention of blood pressure-related adverse events. This guideline gives guiding opinions on optimal blood pressure range for the Chinese oldest old, which applies to the staff of medical and health institutions at all levels nationwide to evaluate the blood pressure levels of the oldest old. It includes the sections of general principles, methods and standards of blood pressure evaluation, measurement conditions, specifications of blood pressure measurement, implementation approaches, etc. The guideline has important directive significance for improving the blood pressure management and decision-making level of the Chinese oldest old.

ABSTRACT

The oscillometric monitor is a noninvasive method used for measuring blood pressure in dogs and cats. Despite widely used, there is a large variability in the accuracy of oscillometric monitors, which may also be influenced by the location of the blood pressure cuff. The Doppler ultrasound is another non-invasive method that was shown to measure blood pressure with good accuracy and precision in small animals. The present study aimed to determine the agreement between systolic arterial pressure (SAP) measured by the Prolife P12 oscillometric monitor with 2 cuff locations and the Doppler ultrasound in anesthetized dogs. Dogs scheduled for routine anesthetic procedures were included in the study, which was carried out in 2 phases. In Phase 1, SAP values measured by the Doppler were compared with those measured by the Prolife P12 monitor with the cuff placed at the thoracic limb for both methods. In Phase 2, SAP values measured by the Doppler were compared with those measured by the Prolife P12 monitor, with the cuff placed at the thoracic limb for the Doppler and at the base of the tail for the P12. The cuff width corresponded to approximately 40% of limb or tail circumference. On all occasions, 3 consecutive measurements of SAP were recorded, followed by a single measurement of SAP by the P12, and then other 3 measurements were performed with the Doppler. The arithmetic mean of the 6 SAP measurements with the Doppler was compared with the SAP value measured by the P12 monitor (paired measurements). Agreement between SAP values measured by the Doppler and the P12 monitor was analyzed by the Bland Altman method for calculation of the bias (Doppler - P12) and standard deviation (SD) of the bias. The percentages of differences between the methods with an error ≤ 10 mmHg and ≤ 20 mmHg and Pearson's correlation coefficients were also calculated. Results were compared with the criteria from the American College of Veterinary Internal Medicine (ACVIM) for validation of noninvasive blood pressure methods. A total of 33 dogs were included in Phase 1 and 15 were included in Phase 2. During Phases 1 and 2, 179 and 87 paired measurements were recorded, respectively. Most of the measurements were recorded during normotension (SAP = 90-130 mmHg): 113/179 in Phase 1 and 52/87 in Phase 2. The bias (± SD) for Phases 1 and 2 were -2.7 ± 14.1 mmHg and 7.2 ± 25.8 mmHg. The percentages of differences ≤ 10 mmHg and ≤ 20 mmHg were: Phase 1, 61% and 83%; Phase 2, 41% and 70%. Correlation coefficients were 0.81 and 0.67 for Phases 1 and 2, respectively. According to the ACVIM criteria, maximum values accepted for bias are 10 ± 15 mmHg, the percentages of differences ≤ 10 mmHg and ≤ 20 mmHg should be ≥ 50% and ≥ 80%, respectively, and the correlation coefficient should be ≥ 0.9. When the blood pressure cuff was placed at the thoracic limb, SAP values measured by the P12 monitor met most of the ACVIM criteria, demonstrating good agreement with SAP values measured by the Doppler. The only requirement not met was the correlation coefficient which was 0.81 whereas the recommended is ≥ 0.9. Conversely, when the cuff was placed at the base of the tail, SAP values measured by the P12 monitor did not meet most of the ACVIM criteria indicating that, in anesthetized dogs, SAP measurements with the P12 monitor should be performed with the cuff placed at the thoracic limb. One limitation of this study was that most measurements fell in the normotensive range and the results should not be extrapolated for hypotensive and hypertensive conditions. In conclusion, the Prolife P12 oscillometric monitor demonstrated good agreement with SAP values measured by the Doppler and provides acceptable values in normotensive anesthetized dogs.(AU)

ABSTRACT

Resumen Introducción: La presión de pulso ampliada (PPA) se asocia a un filtrado glomerular calculado ≤ 60/mL/minuto/1.73 m2, por lo que puede ser útil como prueba diagnóstica para identificar a personas con insuficiencia renal crónica (IRC) estadio K/DOQI III-b. Objetivo: Determinar la utilidad de la PPA como prueba diagnóstica de IRC estadio K/DOQI III-b. Método: Estudio de prueba diagnóstica que incluyó a pacientes adultos sin comorbilidades, registrados en la Cohorte de Trabajadores de la Salud. Se utilizó la fórmula CKD-EPI para calcular la filtración glomerular. Se determinó la presión de pulso restando la presión arterial diastólica a la presión arterial sistólica. Se calculó sensibilidad, especificidad, valor predictivo positivo, valor predictivo negativo y prevalencia. Se elaboró una curva ROC para determinar el área bajo la curva. Resultados: Se incluyeron 6215 pacientes. Se observó que una PPA ≥ 50 mm Hg tuvo sensibilidad de 74 %, especificidad de 70 %, valor predictivo positivo de 1 %, valor predictivo negativo de 100 % y prevalencia de 1 %. El punto de inflexión en la curva ROC para identificar IRC K/DOQI III-b fue de 0.71. Conclusión: La PPA ≥ 50 mm Hg es útil como prueba diagnóstica para identificar a personas con IRC estadio K/DOQI III-b.


Abstract Introduction: Increased pulse pressure (IPP) is associated an estimated glomerular filtration ≤ 60/mL/min/1.73 m2; thus, it can be useful as a diagnostic test to identify people with K/DOQI stage III-b chronic kidney disease (CKD). Objective: To determine the usefulness of IPP as a diagnostic test for K/DOQI stage III-b CKD. Method: Diagnostic test study that included adult patients without comorbidities, registered in the Health Workers Cohort. The CKD-EPI formula was used to calculate glomerular filtration. Pulse pressure was determined by subtracting diastolic from systolic blood pressure. Sensitivity, specificity, positive predictive value, negative predictive value and prevalence were calculated using standard formulas. A ROC curve was generated to determine the area under the curve. Results: A total of 6,215 patients were included. An IPP ≥ 50 mmHg was observed to have a sensitivity of 74 %, specificity of 70 %, positive predictive value of 1 %, negative predictive value of 100 % and a prevalence of 1 %. The inflection point in the ROC curve to identify K/DOQI III-b CKD was 0.71. Conclusion: An IPP ≥ 50 mmHg is useful as a diagnostic test to identify people with K/DOQI stage III-b CKD.

ABSTRACT

Resumo Fundamento Apesar de se recomendar a intervenção em equipe no tratamento da hipertensão, resultados dessa abordagem em ambientes do mundo real são escassos na literatura. Objetivos Apresentar os resultados de uma estratégia terapêutica baseada em equipe, de longo prazo, de pacientes hipertensos em um serviço de saúde. Métodos Dados de pacientes hipertensos acompanhados em um centro de tratamento multidisciplinar localizado na região centro-oeste do Brasil em junho de 2017 com pelo menos duas visitas de acompanhamento foram avaliados retrospectivamente. Dados antropométricos, pressão arterial (PA), tempo de acompanhamento, tratamento farmacológico, diabetes, estilo de vida foram coletados da última consulta. Valores de PA < 140 x 90 mmHg em não diabéticos e < 130 x 80 mmHg em diabéticos foram considerados PA controlada. Um modelo de regressão logística foi construído para identificar variáveis independentemente associadas com o controle da PA. O nível de significância adotado foi de p<0.05. Resultados Foram incluídos 1548 pacientes, com média de acompanhamento de 7,6 ± 7,1 anos. A maioria dos pacientes eram mulheres (73,6%; n=1139), com idade média de 61,8 anos. As taxas de controle da PA na amostra total, em não diabéticos e nos diabéticos foram 68%, 79%, e 37,9%, respectivamente. Diabetes associou-se inversamente com controle da PA (OR 0,16; IC95% 0,12-0,20; p<0,001), enquanto idade ≥ 60 anos (OR 1,48; IC95% 1,15-1,91; p=0,003) e sexo feminino (OR 1,38; IC95% 1,05-1,82; p=0,020) apresentaram associação direta. Conclusões Uma taxa de controle de cerca de 70% foi encontrada em pacientes atendidos em um serviço multidisciplinar de tratamento da hipertensão. A fim de melhorar esses resultados, atenção deve ser dada a pacientes diabéticos, com idade menor que 60 anos e do sexo masculino. (Arq Bras Cardiol. 2020; 115(2):174-181)


Abstract Background Although team-based care is recommended for patients with hypertension, results of this intervention in a real-world setting are missing in the literature. Objective To report the results of a real-world long-term team-based care for hypertensive patients we conducted this study. Methods Data of hypertensive patients attending a multidisciplinary treatment center located in the Midwest region of Brazil in June 2017 with at least two follow-up visits were retrospectively assessed. Anthropometric, blood pressure (BP), follow-up time, pharmacological treatment, diabetes and lifestyle data were collected from the last visit to the service. BP values < 140 x 90 mmHg in non-diabetics and < 130 x 80 mmHg in diabetics were considered controlled. A logistic regression model was built to identify variables independently associated to BP control. Significance level adopted p < 0.05. Results A total of 1,548 patients were included, with a mean follow-up time of 7.6 ± 7.1 years. Most patients were female (73.6%; n=1,139) with a mean age of 61.8 ±12.8 years. BP control rates in all the sample, and in non-diabetics and diabetics were 68%, 79%, and 37.9%, respectively. Diabetes was inversely associated with BP control (OR 0.16; 95%CI 0.12-0.20; p<0.001) while age ≥ 60 years (OR 1.48; 95%CI 1.15-1.91; p=0.003) and female sex (OR 1.38; 95%CI 1.05-1.82; p=0.020) were directly associated. Conclusions A BP control rate around 70% was found in patients attending a multidisciplinary team care center for hypertension. Focus on patients with diabetes, younger than 60 years and males should be given to further improve these results. (Arq Bras Cardiol. 2020; 115(2):174-181)

ABSTRACT

Resumo Fundamento O exercício aeróbio contínuo (EC) é uma das principais recomendações não farmacológicas para prevenção e tratamento da hipertensão arterial sistêmica. O EC é seguro e eficaz para reduzir a pressão arterial cronicamente, assim como nas primeiras horas após sua realização, fenômeno conhecido por hipotensão pós-exercício (HPE). O exercício intervalado (EI) também gera HPE. Objetivo Essa revisão sistemática e metanálise buscou comparar a magnitude da HPE entre o EC e EI em adultos. Métodos Realizou-se uma revisão sistemática de estudos publicados em revistas indexadas nas bases PubMed, Web of Knowledge, Scopus e CENTRAL até março de 2020 que compararam a magnitude da HPE entre o EC versus EI. Foi definida HPE entre 45 e 60 minutos pós-exercício. As diferenças entre grupos sobre a pressão arterial foram analisadas por meio do modelo de efeito aleatório. Os dados foram reportados como diferença média ponderada (WMD) e 95% de intervalo de confiança (IC). Valor p menor que 0,05 foi considerado estatisticamente significativo. A escala TESTEX (0 a 15) foi usada para verificação da qualidade metodológica dos estudos. Resultados O EI apresentou HPE de maior magnitude sobre a pressão arterial sistólica (WMD: -2,93 mmHg [IC95%: -4,96, -0,90], p = 0,005, I2 = 50%) e pressão arterial diastólica (WMD: -1,73 mmHg [IC95%: -2,94, -0,51], p = 0,005, I2 = 0%) quando comparado ao EC (12 estudos; 196 participantes). A pontuação dos estudos na escala TEXTEX variou entre 10 e 11 pontos. Conclusões O EI gerou HPE de maior magnitude quando comparado ao EC entre 45 e 60 minutos pós-exercício. A ausência de dados sobre eventos adversos durante o EI e EC nos estudos impede comparações sobre a segurança dessas estratégias. (Arq Bras Cardiol. 2020; 115(1):5-14)


Abstract Background Continuous aerobic exercise (CE) is one of the main non-pharmacological recommendations for hypertension prevention and treatment. CE is safe and effective to reduce blood pressure chronically, as well as in the first few hours after its performance, a phenomenon known as post-exercise hypotension (PEH). Interval exercise (IE) also results in PEH. Objective This systematic review and meta-analysis sought to compare the magnitude of PEH between CE and IE in adults. Methods A systematic review of studies published in journals indexed in the PubMed, Web of Knowledge, Scopus and CENTRAL databases was performed until March 2020, which compared the magnitude of PEH between CE and IE. PEH was defined as between 45-60 minutes post-exercise. The differences between groups on blood pressure were analyzed using the random effects model. Data were reported as weighted mean difference (WMD) and 95% confidence interval (CI). A p-value <0.05 was considered statistically significant. The TESTEX scale (0-15) was used to verify the methodological quality of the studies. Results The IE showed a higher magnitude of PEH on systolic blood pressure (WMD: -2.93 mmHg [95% CI: -4.96, -0.90], p = 0.005, I2 = 50%) and diastolic blood pressure (WMD: -1,73 mmHg [IC95%: 2,94, -0,51], p= 0.005, I2= 0%) when compared to CE (12 studies, 196 participants). The scores of the studies on the TEXTEX scale varied from 10 to 11 points. Conclusions The IE resulted in a higher magnitude of PEH when compared to CE between 45 and 60 minutes post-exercise. The absence of adverse event data during IE and CE in the studies prevents comparisons of the safety of these strategies. (Arq Bras Cardiol. 2020; 115(1):5-14)

ABSTRACT

Resumo Fundamento A hipotensão ortostática (HO) tem sido negligenciada na clínica não havendo estudos sobre sua prevalência na população brasileira. Objetivo Determinar a prevalência de HO e a variação da pressão arterial (PA) após manobra postural no Estudo Longitudinal da Saúde do Adulto. Métodos No presente estudo descritivo da linha de base (N = 14.833 indivíduos, 35-74 anos), os participantes ficavam deitados por 20 minutos e então levantavam ativamente, com a medida da PA em supino e aos 2, 3, e 5 minutos de ortostase. A HO foi definida por queda ≥ 20 mmHg na PA sistólica e/ou queda ≥ 10 mmHg na PA diastólica aos 3 minutos, sendo determinada a sua prevalência com intervalo de confiança de 95% (IC95%). A distribuição da variação da PA após a manobra postural foi determinada numa subamostra (N = 8.011) após remoção de participantes com morbidade cardiovascular e/ou diabetes. Resultados A prevalência de HO foi de 2,0% (IC95%: 1,8 - 2,3), crescente com a idade. Se o critério for a mesma queda pressórica em qualquer das medidas, a prevalência aumenta para 4,3% (IC95%: 4,0 - 4,7). Em presença de HO houve relato de sintomas (tontura, escotomas, náuseas, etc.) em 19,7% dos participantes (IC95%: 15,6 - 24,6) e em apenas 1,4% (IC95%: 1,2 - 1,6) dos sem HO. Os escores-Z −2 das variações da PA antes e após manobra postural na subamostra foram de −14,1 mmHg na PA sistólica e −5,4 mmHg na diastólica. Conclusão A prevalência de HO varia em função do momento da aferição da PA. Os pontos de corte atuais podem subestimar a ocorrência de HO na população. (Arq Bras Cardiol. 2020; 114(6):1040-1048)


Abstract Background Orthostatic hypotension (OH) has been neglected in clinical practice, and there are no studies on its prevalence in the Brazilian population. Objective To determine the prevalence of OH and blood pressure (BP) changes after the postural change maneuver in participants of the Longitudinal Study of Adult Health. Methods In this descriptive study of baseline data (N = 14,833 adults, ages 35 - 74 years), participants remained lying down for 20 minutes and subsequently stood up actively. BP measurements were taken while the participants were supine and at 2, 3, and 5 minutes after standing. OH was defined as a reduction of ≥ 20 mmHg in systolic BP and/or a reduction of ≥ 10 mmHg in diastolic BP at 3 minutes, and its prevalence was determined with a 95% confidence interval (CI). The distribution of BP variation after the postural change maneuver was determined in a subsample (N = 8,011) obtained by removing patients with cardiovascular morbidity and/or diabetes. Results The prevalence of OH was 2.0% (95% CI: 1.8 - 2.3), increasing with age. If the criterion applied were a BP reduction during any measurement, the prevalence would increase to 4.3% (95% CI: 4.0 - 4.7). Symptoms (dizziness, scotoma, nausea, etc.) were reported by 19.7% of participants (95% CI: 15.6 - 24.6) with OH and 1.4% (95% CI: 1.2 - 1.6) of participants without OH. The −2 Z-scores of BP variation before and after the postural change maneuver in the subsample were −14.1 mmHg for systolic BP and −5.4 mmHg for diastolic BP. Conclusion Prevalence of OH varies depending on when BP is measured. Current cutoff points may underestimate the actual occurrence of OH in the population.

ABSTRACT

Resumo Fundamento O acometimento do sistema nervoso autônomo é um dos mecanismos propostos para explicar a progressão da lesão miocárdica na doença de Chagas. Evidências indicam alterações do sistema nervoso simpático e parassimpático desde a fase aguda, e estudos são necessários para se entender os aspectos fisiopatológicos e o valor prognóstico dessas alterações. Objetivo Analisar o comportamento da pressão arterial pela monitorização ambulatorial da pressão arterial (MAPA) em pacientes normotensos com doença de Chagas aguda (DCA) sem envolvimento cardíaco aparente, e a influência da infecção no descenso fisiológico do sono. Métodos Foi realizado a MAPA em 54 pacientes com DCA e utilizado um grupo controle de 54 indivíduos normotensos, pareados para idade e sexo. O nível de significância adotado foi para um erro tipo I (alfa) de 5%. Resultados Em um total de 54 pacientes com DCA ocorreu ausência de descenso sistólico do sono em 74,0%*, ausência de descenso diastólico do sono em 53,7%*, e ausência de descenso sistólico e diastólico do sono (51,8%)*, (*p<0,05). Em 12,9% ocorreu ascensão sistólica da pressão no sono e em 18,5% ascensão diastólica (p<0,05). Conclusão Em pacientes com Doença de Chagas aguda, houve ausência significativa do descenso fisiológico da pressão arterial durante o sono, tanto da pressão arterial sistólica quanto a diastólica, e alguns pacientes apresentaram ascensão noturna desses parâmetros. Esses achados sugerem alterações autonômicas na doença de Chagas desde a fase aguda. (Arq Bras Cardiol. 2020; 114(4):711-715)


Abstract Background The involvement of the autonomic nervous system is one of the mechanisms proposed to explain the progression of myocardial lesion in Chagas disease. Evidences have shown changes in sympathetic and parasympathetic nervous system since the acute phase of the disease, and studies to clarify the pathophysiological and prognostic value of these changes are needed. Objetives To assess blood pressure profile by ambulatory blood pressure monitoring (ABPM) in normotensive patients with acute Chagas disease (ACD) without apparent cardiac damage, and the influence of the infection on nocturnal blood pressure fall. Methods ABPM was performed with 54 patients with ACD and a control group composed of 54 age- and sex-matched normotensive individuals. The alpha level of significance (type I error rate) was set at 5%. Results In the total of 54 patients, 74.0% did not show nocturnal fall in systolic blood pressure, 53.7% did not show nocturnal fall in diastolic blood pressure, and lack of both nocturnal fall in SBP and DBP was observed in 51.8% (*p<0.05). In 12.9% of patients, there was an increase in SBP and in 18.5% increase in DBP (p<0.05). Conclusions In patients with acute Chagas disease, a significant absence of the physiological fall in both systolic and diastolic blood pressure was observed during sleep, and some of the patients showed nocturnal increase in these parameters. These findings suggest autonomic changes in the acute phase of Chagas disease. (Arq Bras Cardiol. 2020; 114(4):711-715)

ABSTRACT

Resumo Fundamento Os efeitos da redução na ingestão do sal sobre a pressão arterial (PA) casual de hipertensos já foram amplamente estudados, entretanto essa análise ainda é escassa no contexto da redução exclusiva do sal de adição na rigidez arterial e em indivíduos normotensos e pré-hipertensos. Objetivo Avaliar os efeitos da redução progressiva na ingestão do sal de adição (de 6 para 4 g/dia) sobre os valores da pressão periférica e central, a rigidez arterial em normotensos, pré-hipertensos e hipertensos. Métodos Ensaio clínico, simples cego com 13 semanas de seguimento. Foram avaliados normotensos (≤130/85 mmHg), pré-hipertensos (≥130 e <139/≥85 e <90 mmHg) e hipertensos estágio 1 (≥140 e <160/≥90 e <100 mmHg). Utilizou-se medida casual e monitorização residencial da PA com aparelho automático OMRON 705CP, medida central da PA com Sphygmocor®, dosagem do sódio urinário de 24h (colhido no intervalo entre cada visita) e mensuração de sal de adição. Foi adotado nível de significância p<0,05 para todas as análises. Resultados Foram avaliados 55 participantes (18 normotensos; 15 pré-hipertensos; 22 hipertensos) com mediana 48 anos (IQ:39-54). Os grupos foram semelhantes em relação a idade e sexo. Não houve diferença entre medidas de PA e excreção de sódio antes e depois da intervenção. Os parâmetros de rigidez arterial também não sofreram alterações significativas. Conclusão A redução gradativa da ingestão de sal de adição num seguimento de 13 semanas não foi capaz de reduzir de maneira significativa os valores periféricos e centrais da PA.

Abstract Background Although the effects of salt intake reduction on casual blood pressure have been extensively studied in hypertensive individuals, data on reductions of added salt on arterial stiffness in both normotensive and prehypertensive subjects are scarce. Objective To evaluate the effects of progressive reduction in added salt intake (from 6 grams to 4 grams per day) on peripheral and central blood pressure and arterial stiffness in normotensive, prehypertensive and hypertensive individuals. Methods This was a single-blinded clinical trial with 13 weeks of follow-up. Normotensive (≤ 130/85 mmHg), prehypertensive (≥ 130 e < 139/≥ 85 e < 90 mmHg) and stage 1 hypertensive individuals (< 139/≥ 85 and < 90 mmHg) were assessed. Casual blood pressure measurements and ambulatory blood pressure monitoring were performed using the automated OMRON 705CP device, and central blood pressure was measured using the Sphygmocor®. Twenty-four-hour urinary sodium excretion and the amounts of added salt consumed were measured. Statistically significance level was set at p < 0.05 for all analysis. Results A total of 55 participants (18 normotensive, 15 prehypertensive and 22 hypertensive), median age 48 years (IQR:39-54) were studied. The groups were not different in age or sex. No difference was observed in blood pressure or sodium excretion levels before and after the intervention. No significant changes in arterial stiffness parameters were observed. Conclusion The progressive reduction in added salt intake during a period of 13 weeks did not cause significant reductions in peripheral and central blood pressure.
