Full textObstructive sleep apnea (OSA) is present in 60-83% of patients with resistant arterial hypertension (RAH). OBJECTIVES: The main objective of this work was to study the effect of continuous positive airway pressure (CPAP) on ambulatory blood pressure (BP) monitoring (ABPM) in patients with RAH and OSA. Secondary objectives were to assess the effects of CPAP on arterial stiffness, endothelial function, and the expression of several biomarkers probably involved in the relationship between RAH and OSA. PATIENTS AND METHODS: A single-center, open-label, prospective, controlled, parallel-group, randomized clinical trial was carried out in 68 patients with RAH and an apnea-hipopnea index (AHI) ≥15 hour-1 measured by conventional polysomnography. The patients were randomized to therapeutic CPAP or no CPAP for 12 weeks, keeping unchanged their antihypertensive treatment (Clinicaltrials.gov nº. NCT00863135). ABPM and blood and urine tests were performed, and central BP, augmentation index at heart rate 75 min-1 (AIx), and carotid-femoral pulse wave velocity (cfPWV) were measured using applanation tonometry (SphygmoCor®) at baseline and after 12 weeks of treatment. In a subgroup of 36 patients, we also measured serum adiponectin and leptin, and biomarkers of inflammation (serum high-sensitivity CRP, TNF-α and IL-6), oxidative stress (urinary F2-isoprostane), and endothelial dysfunction (plasma soluble ICAM-1, endothelin-1, and VEGF). The reactive hiperemia index was measured using digital plethysmography (EndoPAT 2000®) in another 33 patients. Statistical analysis was performed using the SPSS software, version 23. To compare the effect of CPAP between groups, logistic regression was used for binary dependant variables, and covariance analysis for continuous dependant variables, adjusting for their baseline value in both cases. RESULTS: Sixty-five patients completed the study (31 CPAP and 33 controls), 73% male, with a mean (SD) age of 60.5 (7.3) years, body mass index 35.6 (6.3) Kg/m2, 45.3% with diabetes, mean Epworth 11.1 (5.2) points, AHI 53.5 (25.2) [severe OSA, 78.1%], and baseline 24 h BP 139.9(13.9)/78.3(11.9) mmHg, treated with a median of 4 antihypertensive drugs. Mean CPAP use was 4.7 (2.5) h/night. Weight remained stable. When BP changes during the study were compared between both groups, CPAP improved sleepiness and some quality of life measures, and significantly decreased the frequency of non-dipping pattern for diastolic BP (32.2% vs 57.6%, odds ratio 0.27 [95% confidence interval, 0.09-0.81], P=0.02) but no significant differences were found in any BP change (-2,0/-2,1, -3,2/-2,8, and -1,8/-1,9 mmHg for 24 h, night-time and daytime BP changes, respectively) in the intention-to-treat analysis, or when we analyzed only the patients using CPAP ≥4 h/night. The main effect of CPAP was on night-time systolic BP in CPAP adherent patients with uncontrolled hypertension: -5.1 mmHg (95% confidence interval: -12.3 to +2.1; P=0.16). No statistically significant differences were observed between groups when we analyzed changes in central BP, AIx, cfPWV, albuminuria, insulin-resistance (HOMA-IR and QUICKI), adiponectin, leptin, hsCRP, IL-6, TNF-α, urine F2-isoprostane, soluble ICAM-1, endothelin-1, VEGF or RHI after 12 weeks of treatment. CONCLUSIONS: CPAP for 12 weeks decreased the frequency of non-dippers for diastolic BP although ambulatory BP, arterial stifness, endothelial function, and biomarkers of insulin-resistance, inflammation, oxydative stress, and endothelial dysfunction did not change significantly in patients with RAH and moderate to severe OSA.

Full textBackground: Poor adherence to antihypertensive therapy is a frequent cause of resistant hypertension (RH). The real prevalence of true RH is still unknown due to the difficulty to accurately estimating adherence to the antihypertensive drug in clinical practice. Objective: Compare the direct and indirect methods of assessing adherence to hypertension treatment, measure the adherence to the drug treatment by the direct method in patients with RH, estimate the prevalence of true RH and to identify clinical and demographic characteristics associated with adherence. Methods: Patients with RH were enrolled: office blood pressure (BP) above goal (systolic BP > 140mmHg and/or diastolic BP > 90mmHg), taking three or more antihypertensive drugs of different classes at optimal dose, which one of them should be a diuretic; or office BP below goal (systolic BP < 140mmHg and/or diastolic BP< 90mmHg), taking four or more antihypertensive drugs. Adherence was assessed by direct method of High Pressure Liquid Chromatography (HPLC) analysis for antihypertensive drugs, in 4 different urine samples, in a 30-day interval. For comparison, five indirect methods of adherence assessment were performed simultaneously: pill count, MMAS-8 questionnaire, patient self-report, physician judgement and pharmaceutical judgement. Patient was considered adherent by direct method if every antihypertensive drug was found in 3 urine samples at least; if he consumed 80% of prescribed medication at least; if he reached score >= 7 on the MMAS-8; >= 4 on self-report, physician judgement and pharmaceutical judgement. Kappa correlation coefficient (KCC) was performed to evaluate the agreement between the methods. Results: 50 patients with HR were enrolled: 68% women, mean age 55,1 ± 8,2 years, body mass index 29 ± 3,3 kg/m2, office BP 149/86 ± 26/15 mmHg, mean 24 hs by Ambulatory Blood Pressure Monitoring (ABPM) 127/82 ± 19/11 mmHg and average of antihypertensive druhs prescribed 4,6 ± 0,7 classes. 66% of patients were non-adherent by direct method: 42% classified as pseudoresistant hypertensive patients due to low adherence and only 18% as true resistant hypertensive. Agreement between methods was low according to KCC, ranging from non-existent [pill count (-0,040), pharmaceutical judgement (-0,040) and self-report (-0,132)] to minimum [MMAS-8 questionnaire (0,055) and physician judgement (0,126)]. There is no association between clinical and demographic characteristics and adherence by direct methods. Conclusion: The prevalence of non-adherence is high in patients with RH, which is probably the main cause of resistance to antihypertensive treatment. The indirect adherence methods evaluated did not show agreement with the direct method, and its use as a tool to measure adherence in clinical practice should be questionable

Full textIntroduction Hypertension (HTN) is an asymptomatic insidious common chronic disease that is easily detected and usually treatable, but it can lead to fatal complications if not controlled. It is one of the main problems of public health worldwide and its proper treatment is still a challenge. Helping to make this condition’s control more difficult and worsening its outcome, there is the fraction known as resistant hypertension. Resistant hypertensive patients do not reach the blood pressure levels considered target for prevention of potentially fatal outcomes although they are treated with multiple antihypertensive drugs. This resistance can be explained by several factors such as obstructive sleep apnea (OSA), which is a disease of high prevalence among hypertensive people and even higher among people with resistant hypertension, whose association has been largely proved, and the more critical the OSA, the greater the association. The syndrome is characterized by episodes of upper airway obstruction during sleep leading to hypoxemia and multiple arousals, associated with day sleepiness. The pillar of the OSA treatment is keeping the airway’s patency during the sleep. The principal and most used treatment is providing continuous positive airway pressure (CPAP) during the sleep period. Literature shows variable reduction in blood pressure levels of patients with HTN and OSA treated with CPAP. However, there is scarcity of data and studies with strong methodology to show efficacy in the treatment with CPAP as a hypotensive agent in the most critical and of difficult control group, truly resistant hypertensive. Methods A randomized, double-blind parallel placebo-controlled clinical trial was carried out in consecutive resistant hypertensive patients from the Hypertension Unit and from the Noninvasive Method Unit from Hospital de Clinicas de Porto Alegre (HCPA). Truly resistant patients (with good adherence, without white-coat effect, with blood pressure correctly measured and without known secundary cause), with OSA at least moderate, in other words, with apneahypopnea index (AHI) equal or higher than 15, were randomized for one out of two treatments: sham-CPAP (maximum pressure: 1cm H20) or active CPAP (pressure ranging from 6 and 12cm H20, self-adjustable). Blood pressure (BP) measured in the office, 24-hour ambulatory blood pressure monitoring (ABP monitoring) and anthropometric measurement before and after eight weeks (two months) of randomization, were measured as well. Results During the period between February 2008 and April 2013, 47 patients were randomized to receive active CPAP or sham-CPAP for two months. Most of the participants were men (57%), middle-aged (average: 59.4 ± 7.7years), overweight (BMI: 29.8 ±4.4), with mean of measured blood pressure in office 165 ± 20/96 ± 16 mmHg, taking in average 4±1 antihypertensive drug and with moderate OSA , median of AHI: 20 (interquartile range 18-31).The patients’ basal characteristics in both groups were similar. The data analysis followed the intention-to-treat principle and, compared to the sham-CPAP, the group treated with active CPAP showed a decrease in the systolic blood pressure in the 24- hour average. The reduction in the sham-CPAP group was 0,7mmHg (CI 95% -5,3 ; 6,7) whereas the active CPAP group showed a reduction of 10mmHg (CI 95% 3.8;16,2), P=0.035. The difference was mostly due to the effect in the nighttime period. Conclusion We identify that true resistant HTN does not seem to be as frequent as described, possibly because most prevalence studies include patients with inadequate technics of blood pressure measurement, without adherence evaluation, or even knowing whether or not antihypertensive medication’s doses were optimized. Among the main findings in this thesis is the reduction of blood pressure with the use CPAP in truly resistant hypertensive people with OSA at least moderate.

Resumo: Introdução: A disfunção diastólica do ventrículo esquerdo (DDVE) e a hipertrofia ventricular são consideradas marcadores frequentes para lesão cardíaca e fatores de risco de progressão para insuficiência cardíaca congestiva (ICC), especialmente em pacientes com hipertensão arterial resistente (HAR). A redução dos níveis pressóricos arteriais pode melhorar a disfunção diastólica do ventrículo esquerdo e os sintomas de insuficiência cardíaca. Entretanto, frequentemente esta redução não é atingida nos pacientes com HAR. Inibidores da fosfodiesterase 5 (PDE5) apresentam efeitos vasodilatadores discretos e, recentemente, se demonstrou que a administração de sildenafil a ratos hipertensos melhorou a disfunção diastólica do ventrículo esquerdo, através de ação direta sobre os miócitos cardíacos, evidenciando a presença de PDE5 neste tecido. Objetivo: Avaliar se o uso de um inibidor de PDE5 de longa duração (tadalafil) melhora a DDVE em pacientes com HAR de maneira independente de outros mecanismos secundários. Casuística e Métodos: Realizou-se um estudo intervencionista, cego, controlado por placebo, cruzado de uma via, incluindo 19 pacientes com HAR e DDVE. Inicialmente, receberam por via oral uma dose diária de placebo por 14 dias, com realização de medidas da pressão arterial de consultório e MAPA, avaliação da função endotelial (técnica de FMD), ecocardiograma e medidas de concentrações sanguíneas de BNP-32, GMPc e nitrito, antes e após o período de administração. Posteriormente, repetimos o mesmo procedimento, mas substituindo o placebo por tadalafil 20mg por dia. Ao final, as variáveis obtidas foram comparadas antes e após os usos de tadalafil e placebo, utilizando-se o método t de student pareado, com ?<0,05. Resultados: os pacientes apresentaram melhora da DDVE, demonstrada pela velocidade da onda E de 67,8±18,3cm/s para 77,8±16,0cm/s (p=0,025); relação E/A de 0,9±0,3 para 1,08±0,3 (p=0,01); tempo de desaceleração da onda E de 234,1±46,0ms para 194,4±43,3ms (p<0,01); tempo de relaxamento isovolumétrico de 128,7±17,6ms para 96,8±26,9ms (p<0,01); velocidade de onda E' lateral de 7,7±2,1cm/s para 8,8±2,8cm/s (p=0,025); velocidade de onda S' septal de 6,3±1,4cm/s para 7,7±1,7cm/s (p<0,01) e velocidade de onda S' lateral de 7,5±2,3cm/s para 8,3±2,2cm/s (p=0,014) (todas as variáveis expressas como em média e desvio-padrão). Houve, também, redução nos níveis de BNP-32 de 143±33,3 para 119,3±31,3 pg/mL e aumento no GMPc de 62,4±32,2 para 112,6±75,3pmol/mL. A concentração de nitrito foi semelhante com o uso de placebo e tadalafil. Em relação às medidas de pressão arterial, independentemente do método, também apresentam valores semelhantes antes e após o uso do fármaco, assim como a função endotelial. Os pacientes sob ação do placebo, não mostraram alterações em nenhuma das variáveis avaliadas. Conclusões: Os resultados sugerem que o uso de tadalafil melhora o relaxamento do ventrículo esquerdo em pacientes com HAR, independente da pressão arterial e da função endotelial, podendo constituir um importante tratamento adjunto em pacientes hipertensos sintomáticos com DDVE
Abstract: Introduction: Left ventricular hypertrophy and diastolic dysfunction (LVDD) remain frequent markers of cardiac damage and risk of progression to symptomatic heart failure (HF), especially in resistant hypertension (RHTN). Lowering BP may improve diastolic function and relieve HF symptoms; however, very often this target is not achieved in RHTN subjects. PDE-5 inhibitors have mild systemic vasodilatory effects, and recently, we demonstrated that administration of sildenafil in hypertensive rats improves LVDD, acting in cardiac myocytes with PDE5 expression in this tissue. Objective: To analyze if a long-acting PDE-5 inhibitor (tadalafil) may be clinically useful for improving LVDD in RHTN patients. Methods: We developed a single- blinded, placebo-controlled, one-way crossover, interventional study that enrolled 19 patients with RHTN and LVDD. At first, subjects were given a placebo daily oral dosage, for 2 weeks and they were submitted to blood pressure measurements (both ABPM and office), endothelial function (FMD) assessment, echocardiographic study and plasmatic BNP-32, cGMP and nitrite levels, before and after this 2-week period. Next, subjects were submitted to the same protocol receiving tadalafil (20 mg) orally instead of placebo. Variables were compared before and after placebo and tadalafil administration, using the paired student's t-test. The level of significance (?) accepted was less than 0.05. Results: Patients had an improvement in LVDD represented by changes in E-wave peak velocity from 67.8±18.3cm/s to 77.8±16.0cm/s (p=0.025), E/A ration from 0.9±0.3 to 1.08±0.3 (p=0.01), E wave deceleration time from 234.1±46.0ms to 194.4±43.3ms (p<0.001), isovolumic relaxation time from 128.7±17.6ms to 96.8±26.9ms (p<0.001), lateral E' wave velocity from 7.7±2.1cm/s to 8.8±2.8cm/s (p=0.025), septal S' wave velocity from 6.3±1.4cm/s to 7.7±1.7cm/s (p<0.01) and lateral S' wave velocity from 7.5±2.3cm/s to 8.3±2.2cm/s (p=0.014) (Values are expressed as mean ± standard deviation). We also noticed a decrease in BNP-32 levels from 143±33.3 to 119.3±31.3 pg/mL and an increase in cGMP levels from 62.4±32.2 to 112.6±75.3pmol/mL. No significant differences were detected in office and ABPM measurements, in endothelial function and nitrite levels. Conclusion: The current findings suggest that tadalafil enhances LV relaxation in resistant hypertensive patients and, despite its mild antihypertensive effect, may serve as an important adjunct to treat symptomatic hypertensive patients with evident LVDD
