Entrenamiento muscular inspiratorio en pacientes con insuficiencia cardíaca: una revisión de revisiones / Inspiratory muscle training in patients with heart failure: a review of reviews

RESUMEN: El objetivo de esta revisión fue conocer la influencia del entrenamiento muscular inspiratorio (EMI) sobre la capacidad aeróbica y la fuerza muscular inspiratoria (FMI) en pacientes con insuficiencia cardíaca (IC). Realizamos una revisión de revisiones sistemáticas en PubMed y Web of Science hasta agosto de 2019. Se identificaron un total de 2053 artículos, de los cuales 4 se seleccionaron para esta revisión. Se utilizó la herramienta 'Assessment of Multiple Systematic Reviews 2' (AMSTAR-2) para evaluar la calidad de los estudios. En los estudios incluidos se examinaron un total de 10 intervenciones diferentes con 250 pacientes (rango edad media= 53-76 años). Todos los estudios presentaron nivel de confianza alto (AMSTAR-2). El EMI presentó mejoras significativas sobre la capacidad aeróbica (test de la marcha de 6 minutos: 46.66-71.04 metros; p<0.05 y VO2pico: 2.59-2.65 mL/kg-1/min-1; p<0.01) y la FMI (presión inspiratoria máxima: 16.57-23.36 cmH2O, p<0.05) en comparación al grupo control. Programas de intervención de EMI con una duración de 12 semanas reportaron mayores mejorías sobre la capacidad aeróbica y la FMI en comparación a programas de intervención de menor duración. El EMI es un tratamiento importante y necesario en la rehabilitación cardíaca de pacientes con IC. Son necesarios más estudios que analicen los efectos de diferentes rangos en las características del EMI.

ABSTRACT: The aim of this review was to understand the influence of inspiratory muscle training (IMT) on aerobic capacity and inspiratory muscle strength (IMS) in patients with heart failure (HF). We conducted a review of systematic reviews in PubMed and Web of Science up to August 2019. A total of 2053 articles were identified, of which 4 were selected for this review. The 'Assessment of Multiple Systematic Reviews 2' (AMSTAR-2) tool was used to assess the quality of the studies. In the included studies, a total of 10 different interventions with 250 patients (mean age range = 53-76 years) were examined. All the studies presented high confidence level (AMSTAR-2). IMT showed significant improvements in aerobic capacity (6-minute walk test: 46.66-71.04 meters; p<0.05 and VO2peak: 2.59-2.65 mL/kg-1/min-1; p<0.01) and IMS (maximal inspiratory pressure: 16.57-23.36 cmH2O, p<0.05) in this population compared to the control group and IMF in this population. IMT intervention programs lasting 12 weeks reported greater improvements in aerobic capacity and IMS compared to shorter intervention programs. IMT is an important and necessary treatment in cardiac rehabilitation of patients with HF. More studies are needed to analyze the effects of different ranges of the IMT characteristics.

Effects of Inspiratory Muscle Training Using an Electronic Device on Patients Undergoing Cardiac Surgery: A Randomized Controlled Trial

Abstract Background Cardiac surgery causes pathophysiological changes that favor the occurrence of pulmonary and functional complications. Objective To investigate the effects of inspiratory muscle training (IMT) with an electronic device on patients undergoing cardiac surgery. Methods A randomized controlled trial was conducted with 30 adult patients undergoing elective cardiac surgery. A control group (CG) received conventional physical therapy care, and an intervention group (IG) received IMT using the POWERbreathe K5® electronic device. Two daily sessions of physical therapy were performed at the intensive care unit and one daily session at the ward until the sixth postoperative day. The following variables were measured preoperatively and on the sixth postoperative day, in both groups: inspiratory muscle strength, dynamic inspiratory muscle strength, and peak inspiratory flow. Data distribution was evaluated by the Shapiro-Wilk test. Analysis of variance was used, and the results were considered statistically significant when p < 0.05. Results Maximal inspiratory pressure (71.7 ± 17.1 cmH2O vs 63.3 ± 21.3 cmH2O; p = 0.11], S-index (52.61 ± 18.61 vs 51.08 ± 20.71), and peak inspiratory flow [(2.94 ± 1.09 vs 2.79 ± 1.26)] were maintained in the IG but had a significant reduction in the CG. Conclusion IMT performed with an electronic device was effective at maintaining inspiratory muscle strength, dynamic inspiratory muscle strength, and peak inspiratory flow when compared to conventional physical therapy.

Reabilitação cardiopulmonar em pacientes pós-COVID-19: série de casos / Cardiopulmonary rehabilitation in post-COVID-19 patients: case series

RESUMO A história natural da doença e o tratamento de pacientes após a COVID-19 ainda se apresentam em construção. Os sintomas são persistentes, mesmo em casos leves, e as consequências decorrentes da infecção incluem fadiga, dispneia, taquicardia, perda de massa muscular e diminuição da capacidade funcional. Sobre a reabilitação cardiopulmonar, parece haver melhora na capacidade funcional, na qualidade de vida e no prognóstico com o Teste da Caminhada de 6 Minutos, sendo este utilizado como avaliador prognóstico e terapêutico. Assim, o objetivo deste relato de casos é descrever a experiência de quatro casos, de diferentes gravidades, que realizaram um programa de reabilitação cardiopulmonar pós-COVID-19, avaliados com Teste da Caminhada de 6 Minutos, força muscular periférica e duplo produto em repouso, para verificar o efeito da reabilitação após 3 meses de protocolo de, no mínimo, 300 minutos por semana. Os quatro casos apresentaram aumento da distância percorrida no teste da caminhada entre 16% e 94%. Houve aumento da força muscular periférica em 20% até seis vezes seu valor inicial, e a redução do duplo produto em repouso variou entre 8% e 42%. O programa de reabilitação cardiopulmonar apresentou impacto positivo nos casos acompanhados, com melhora da capacidade funcional, mesmo com a variabilidade da gravidade dos casos pós-COVID-19.

ABSTRACT The natural history of the disease, and the treatment of post-COVID-19 patients, are still being built. Symptoms are persistent, even in mild cases, and the infection consequences include fatigue, dyspnea, tachycardia, muscle loss, and reduced functional capacity. Regarding cardiopulmonary rehabilitation, there seems to be an improvement in functional capacity, quality of life, and prognosis with the 6-Minute Walk Test used as a prognostic and therapeutic evaluator. Therefore, this case series report aims to present our experience with four cases of different severity levels, involved in a post-COVID-19 cardiopulmonary rehabilitation program. These patients were assessed with the 6-Minute Walk Test, peripheral muscle strength, and double product at rest, to assess the results after a three-month rehabilitation protocol of at least 300 minutes per week. The four patients had their distance covered during the walk test increased between 16% and 94%. Peripheral muscle strength was improved by 20% to six times the baseline values, and double product at rest was reduced by 8% to 42%. The cardiopulmonary rehabilitation program had a positive impact on these cases, improving functional capacity despite the different severity levels in these post-COVID-19 cases.

Singing Voice Therapy Revisited / Revisión de la terapia de voz cantada

Introduction. Singing is a type of sportive activity and, like sports medicine, profes-sional voice medicine is interested in the habilitation and rehabilitation of the vocal performer. The vocal needs of the professional vocal performer may not be similar to other professional or non-professional voice users. Like a professional athlete, a vocal performer's ability to perform for many decades at a high level will be enhanced by basing artistic and lifestyle decisions on a scientifically sound foundation. Objective. The aim of this study is to present a multidimensional introduction to the methods of SVT, incorporating the principles of sport and exercise medicine, and physical therapy and rehabilitation.Reflection. Singing voice therapy needs to provide answers to "what", "why", "how", and "when" questions. SVT must first correctly identify the problem, leading to the "how to do" solutions for a wide variety of cases, followed by a schedule of prescribed activities including answers to the "why" question (which exercise relates to which muscle). The periodization and motor learning principles provide a temporal answer to the "when" question when developing habilitation and/or rehabilitative protocols.Conclusion. Singing is not only an artistic expression, but also a sportive performance. The clinical approach to professional voice is a multidimensional and multilayered team effort. All practices are structured by blending scientific and ped-agogical knowledge

Introducción. El canto es una forma de actividad deportiva y, al igual que la medicina deportiva, la medicina vocal profesional se interesa por la habilitación y rehabilitación del intérprete vocal. Las necesidades vocales del intérprete vocal profesional pueden no ser similares a las de otros usuarios de voz profesionales o no profesionales. Al igual que un atleta profesional, la capacidad de un intérprete vocal para desempeñarse durante muchas décadas a un alto nivel se mejorará al basar las decisiones artísticas y de estilo de vida en un fundamento científicamente sólido. Objetivo. El objetivo de este estudio es presentar una introducción multidimensional a los métodos de TSV, incorporando los principios de la medicina del deporte y el ejercicio, y la fisioterapia y rehabilitación. Reflexión. La terapia de la voz cantada debe proporcionar respuestas a preguntas de "qué", "por qué", "cómo" y "cuándo". SVT primero debe identificar correctamente el problema, lo que lleva a las soluciones de "cómo hacer" para una amplia variedad de casos, seguido de un programa de actividades prescritas que incluyen respuestas a la pregunta "por qué" (qué ejercicio se relaciona con qué músculo). Los principios de periodización y aprendizaje motor proporcionan una respuesta temporal a la pregunta de "cuándo", al desarrollar protocolos de habilitación y/o rehabilitación. Conclusión. Cantar no es solo una expresión artística, sino también una actuación deportiva. El enfoque clínico de la voz profesional es un esfuerzo de equipo multidimensional y de múltiples capas. Todas las prácticas están estructuradas, al combinar conocimientos científicos y pedagógicos.

ABSTRACT To analyze respiratory muscle performance in exercise practitioners using the Reformer of Pilates method after a 12-session training. This study was carried out with 24 volunteers, healthy young adults, non-smokers and non-regular exercisers, divided into control group (CG) and trained group (TG). The TG participated in a training program executing 6 exercises in the Reformer apparatus. Both groups were submitted to the initial and final evaluations to analyze the performance of the respiratory muscles through the manovacuometry and electromyography of the rectus abdominis muscle. The Shapiro-Wilk test was used to verify the data normality. Two-way analysis of variance was used for the comparisons between the groups (TG and CG) and moments (Initial and Final). For multiple comparisons, the Scheffé post hoc test was used. The groups Control and Trained were paired by age and BMI by paired t test. P <0.05 was considered for significance. A significant difference (p=0039) was observed between the initial (116.6 ± 12.8) and final (120 ± 12.8) values of MIP in the trained group, as well as between baseline values (75.3 ± 12.4) and final (89.3 ± 13.7) of MEP in the same group (p=0.0005). For electromyography, a significant difference (p=0.03) was observed between the initial (42.1 ± 15.8) and final (76.7 ± 37.1) moments of the TG for the left rectus abdominis muscle. The conclusion is that the 12 Pilates sessions using the Reformer apparatus improve respiratory muscle performance, increasing the inspiratory and expiratory muscle strength.

Physiotherapeutic approaches and the effects on inspiratory muscle force in patients with chronic obstructive pulmonary disease in the pre-operative preparation for abdominal surgical procedures / Abordagens fisioterapêuticas e os efeitos na força muscular inspiratória em pacientes com doença pulmonar obstrutiva crônica no preparo para procedimentos cirúrgicos abdominais

ABSTRACT Background: Abdominal disorders can alter respiratory function and increase the morbidity and mortality of patients with chronic obstructive pulmonary disease. Aim: To improve the physiotherapeutic and muscular capacity in chronic obstructive pulmonary muscular inspiration in the preoperative preparation in abdominal surgeries. Method: Retrospective and documentary study using SINPE © , clinical database software of patients with chronic obstructive pulmonary disease and candidates to abdominal operation. The sample consisted of 100 men aged 55-70 years, all with chronic obstructive pulmonary disease who underwent preoperative physiotherapeutic treatment. They were divided into two groups of 50 individuals (group A and group B). In group A the patients were treated with modern mobility techniques for bronchial clearance and the strengthening of the respiratory muscles was performed with IMT ® Threshold. In group B the treatment performed for bronchial obstruction was with classic maneuvers and for the strengthening of the respiratory muscles for flow incentive was used Respiron ® . Results: Both groups obtained improvement in the values ​​of the PiMáx after the different treatments. Group A obtained greater change in the intervals and a more significant increase of the values of the PiMax in relation to the average pre and post-treatment. However, when analyzing the variance and the standard deviation of the samples, group B presented the best results showing more homogeneity. Conclusions: The modern and traditional bronchial clearance techniques associated with inspiratory muscle training were equally effective in gaining inspiratory muscle strength with increased Pmax. In this way, the two can be used in the preoperative preparation of patients with chronic obstructive pulmonary disease and referred to abdominal operations.

RESUMO Racional: As operações abdominais podem alterar a função respiratória e aumentar a morbimortalidade dos operados com doença pulmonar obstrutiva crônica. Objetivo: Avaliar que técnica fisioterapêutica apresenta melhor efeito na força muscular inspiratória dos pacientes com doença pulmonar obstrutiva crônica no preparo pré-operatório em operações abdominais. Método: Estudo retrospectivo e documental usando o SINPE©, software de banco de dados clínicos de pacientes portadores de doença pulmonar obstrutiva crônica e candidatos a operações abdominais. A amostra foi composta de 100 homens com idade entre 55-70 anos, todos com DPOC com indicação para operação abdominal e que realizaram tratamento fisioterapêutico pré-operatório. Foram divididos em dois grupos de 50 indivíduos (grupo A e grupo B). No grupo A o tratamento realizado para a desobstrução brônquica foi com técnicas modernas e para fortalecimento dos músculos respiratórios foi realizado o Threshold IMT®. No grupo B o tratamento realizado para desobstrução brônquica foi com técnicas tradicionais e para fortalecimento dos músculos respiratórios foi realizado incentivador a fluxo Respiron®. Resultados: Ambos os grupos obtiveram melhora dos valores da PiMáx (Pressão inspiratória Máxima) após o tratamento com abordagens diferentes com melhora também nos intervalos da PiMáx. O grupo A obteve maior mudança nos intervalos e aumento mais significativo dos valores da PiMáx em relação à média pré e pós tratamento. Porém, ao analisar a variância e o desvio-padrão das amostras, o grupo B apresentou melhor distribuição que o grupo A mostrando que seus resultados na amostra foram mais homogêneos. Conclusões: As técnicas modernas e tradicionais de desobstrução brônquica associadas ao treinamento muscular inspiratório mostraram-se igualmente eficazes no ganho de força dos músculos inspiratórios com aumento da PiMáx. Dessa forma as duas podem ser utilizadas no preparo pré-operatório de pacientes com DPOC e encaminhados para operações abdominais.

Influence of pulmonary rehabilitation on clinical characteristics in patients with chronic heart failure and chronic obstructive pulmonary disease / Influência da reabilitação pulmonar nas características clínicas em pacientes com insuficiência cardíaca crônica e doença pulmonar obstrutiva crônica

Background: The improvement of treatment strategies in patients with chronic obstructive pulmonary disease (COPD) and especially with comorbid pathology should provide rational conversion of standard schemes of therapy and rehabilitation in accordance with their clinical, pathogenic, functional and economic feasibility. Objective: To assess the influence of pulmonary rehabilitation on clinical characteristics in patients with chronic heart failure (CHF) and concomitant COPD. Methods: The study included 102 patients with CHF and concomitant COPD (males, 62%; mean age, 68.2 ± 4.5 years). All patients were divided into two groups: control group (CG) (n = 54), received only standard therapy of CHF and COPD; and intervention group (IG) (n = 48) were additionally taught the full yogic breathing as a program of pulmonary rehabilitation. Calculation of points by clinical evaluation scale (CES), assessment of CHF functional class (FC) (NYHA) and 6-minute walk test (6MWT - with the evaluation of dyspnea by the Borg scale) were performed in all patients on admission to the department and at discharge. Significant association was defined by p value < 0.05. Results: At baseline, there were no significant differences in clinical characteristics of the patients and studied parameters between the groups. At discharge both groups showed significant reduction of dyspnea by the Borg scale (in CG: from 7.2 ± 0.8 points to 5.2 ± 0.3; in IG: from 7.4 ± 0.6 points to 3.2 ± 0.4), the number of points by CES (in CG: from 10.8 ± 0.3 points to 7.2 ± 0.4; in IG: from 10.7 ± 0.6 points to 5.9 ± 0.6). Increase in exercise tolerance (by the distance of 6MWT) was observed in both groups (in CG: from 215 ± 24 m to 275 ± 22 m; in IG: from 219 ± 21 m to 308 ± 24 m). The changes were more significant in IG compared to CG. We observed the prominent decrease in CHF FC and length of hospital stay in IG. Conclusions: Application of full yogic breathing as the program of pulmonary rehabilitation in addition to standard therapy of the patients with CHF and COPD is associated with a significant decrease in CHF FC, an increase in exercise tolerance and a reduced length of hospital stay

Effects of high-intensity inspiratory muscle training associated with aerobic exercise in patients undergoing cabg: randomized clinical trial

Abstract Objective: Evaluate the interaction between high-intensity inspiratory muscle training (IMT) and aerobic exercise on physical capacity, respiratory muscle strength, peripheral muscle strength, and quality of life of patients who underwent coronary artery bypass grafting (CABG). Methods: Twenty-four patients underwent CABG were randomized into two groups. During 36 sessions, one group received IMT associated with aerobic exercise and the other group received only aerobic exercise. Primary outcome was the distance in the six-minute walk distance (6MWD) test. Secondary outcomes included respiratory muscle strength, peripheral muscle strength, and quality of life. Measures were taken at the baseline, at the 12th session, the 24th session, and 36th session. Results: Baseline characteristics were similar between the groups. There was no statistically significant difference between the two groups in any outcome [6MWD - P=0.935; peak oxygen consumption (PeakVO2) - P=0.853; maximal inspiratory pressure (MIP) - P=0.243; maximal expiratory pressure (MEP) - P=0.268; sitting-rising test (SRT) - P=0.212], but there was interaction in MIP (P=0.000) and all outcomes improved in the two groups (6MWD - P=0.000; PeakVO2 - P=0.000; MIP - P=0.000; MEP - P=0.000; SRT - P=0.000). Conclusion: There was an improvement of all outcomes in both groups, but IMT was not able to provide additional benefits. The use of this combination should be used with caution to not generate higher costs in the rehabilitation process of these patients.

Combination of preoperative pulmonary and nutritional preparation for esophagectomy

Abstract Purpose: To compare pulmonary and nutritional parameters before and after inspiratory muscle training (IMT) and enteral feeding support in patients with esophageal disease undergoing preoperative outpatient follow-up. Methods: Thirty patients with a mean age of 55.83 years, 16 men and 14 women, were included. Pulmonary assessment consisted of the measurement of MIP, MEP, and spirometry. Anthropometric measurements and laboratory tests were performed for nutritional assessment. After preoperative evaluation, inspiratory muscle training and enteral nutrition support were started. A p<0.05 was considered statistically significant. Results: After an outpatient follow-up period of 4 weeks, a significant increase in MIP (-62.20 ± 25.78 to -81.53 ± 23.09), MEP (73.4 ± 31.95 to 90.33 ± 28.39), and FVC (94.86 ± 16.77 to 98.56 ± 17.44) was observed. Regarding the anthropometric variables, a significant increase was also observed in BMI (20.18 ± 5.04 to 20.40 ± 4.69), arm circumference (23.38 ± 3.28 to 25.08 ± 4.55), arm muscle circumference (21.48 ± 3.00 to 22.07 ± 3.36), and triceps skinfold thickness (5.62 ± 2.68 to 8.33 ± 6.59). Conclusion: Pulmonary and nutritional preparation can improve respiratory muscle strength, FVC and anthropometric parameters. However, further studies are needed to confirm the effectiveness of this preoperative preparation.

The influence of inspiratory muscle training combined with the Pilates method on lung function in elderly women: A randomized controlled trial

OBJECTIVE: Aging is progressive, and its effects on the respiratory system include changes in the composition of the connective tissues of the lung that influence thoracic and lung compliance. The Powerbreathe® K5 is a device used for inspiratory muscle training with resistance adapted to the level of the inspiratory muscles to be trained. The Pilates method promotes muscle rebalancing exercises that emphasize the powerhouse. The aim of this study was to evaluate the influence of inspiratory muscle training combined with the Pilates method on lung function in elderly women. METHODS: The participants were aged sixty years or older, were active women with no recent fractures, and were not gait device users. They were randomly divided into a Pilates with inspiratory training group (n=11), a Pilates group (n=11) and a control group (n=9). Spirometry, manovacuometry, a six-minute walk test, an abdominal curl-up test, and pulmonary variables were assessed before and after twenty intervention sessions. RESULTS: The intervention led to an increase in maximal inspiratory muscle strength and pressure and power pulmonary variables (p<0.0001), maximal expiratory muscle strength (p<0.0014), six-minute walk test performance (p<0.01), and abdominal curl-up test performance (p<0.00001). The control group showed no differences in the analyzed variables (p>0.05). CONCLUSION: The results of this study suggest inspiratory muscle training associated with the Pilates method provides an improvement in the lung function and physical conditioning of elderly patients.

Respiratory muscle training improves diaphragm citrate synthase activity and hemodynamic function in rats with heart failure

Abstract INTRODUCTION: Enhanced respiratory muscle strength in patients with heart failure positively alters the clinical trajectory of heart failure. In an experimental model, respiratory muscle training in rats with heart failure has been shown to improve cardiopulmonary function through mechanisms yet to be entirely elucidated. OBJECTIVE: The present report aimed to evaluate the respiratory muscle training effects in diaphragm citrate synthase activity and hemodynamic function in rats with heart failure. METHODS: Wistar rats were divided into four experimental groups: sedentary sham (Sed-Sham, n=8), trained sham (RMT-Sham, n=8), sedentary heart failure (Sed-HF, n=7) and trained heart failure (RMT-HF, n=7). The animals were submitted to a RMT protocol performed 30 minutes a day, 5 days/week, for 6 weeks. RESULTS: In rats with heart failure, respiratory muscle training decreased pulmonary congestion and right ventricular hypertrophy. Deleterious alterations in left ventricular pressures, as well as left ventricular contractility and relaxation, were assuaged by respiratory muscle training in heart failure rats. Citrate synthase activity, which was significantly reduced in heart failure rats, was preserved by respiratory muscle training. Additionally, a negative correlation was found between citrate synthase and left ventricular end diastolic pressure and positive correlation was found between citrate synthase and left ventricular systolic pressure. CONCLUSION: Respiratory muscle training produces beneficial adaptations in the diaphragmatic musculature, which is linked to improvements in left ventricular hemodynamics and blood pressure in heart failure rats. The RMT-induced improvements in cardiac architecture and the oxidative capacity of the diaphragm may improve the clinical trajectory of patients with heart failure.

Introduction: COPD is characterized by a chronic limitation to airflow that alters the quality of life of the people suffering this illness. The objective of this study is to demonstrate the effects that has a pulmonary rehabilitation program (PRP) designed in primary care using limited resources in a group of COPD patients. Method: Prospective study of 13 patients (5 men, 8 women), age: 74.38 ± 10.12 ( X ¯ ± SD) years-old with COPD, GOLD stage I, II and III, which were submitted for 3 months to a pulmonary rehabilitation program with emphasis on the training of the respiratory muscles and recreational activities like inflating balloons. The variables measured pre and post training were: lung function, six-minute walk test (6MWT), dyspnea using the modified scale from Medical Research Council (mMRC), maximal inspiratory pressure (PIMax) at functional residual capacity (FRC), PIMax at residual volume (RV), time of fatigue resistance of the inspiratory and expiratory muscles (TFRIM and TFREM respectively), quality of life through the COPD assessment Test (CAT) and the circumference of the inflated balloons (CIB) for each patient. Results: Significant changes (p < 0.05) were found in: dyspnea, distance of 6MWT, PIMax at FRC, PIMax at RV, CAT, TFRIM, TFREM and CIB. Conclusions: Our pulmonary rehabilitation program improved the dyspnea, exercise capacity, quality of life and the strength and endurance of the respiratory muscles which was reflected by a greater circumference of the inflated balloons by each patient post-training. Therefore we affirm that it is possible to design a pulmonary rehabilitation program in primary care using limited resources and getting excellent results.

Teste Cardiopulmonar de Exercício na Hipertensão Pulmonar / Cardiopulmonary Exercise Testing in Pulmonary Hypertension

O teste cardiopulmonar de exercício (TCPE) é um exame complementar que fornece importantes dados sobre a real capacidade funcional e respostas do metabolismo, ventilação e trocas gasosas do paciente. Deste modo, o TCPE permite classificar a aptidão cardiorrespiratória de um indivíduo e identificar distúrbios que limitam a continuidade do exercício, através da análise de diversas variáveis extraídas deste método propedêutico diagnóstico e prognóstico. Neste sentido, situações relativamente comuns mas pouco identificadas na prática clínica, como a hipertensão pulmonar (HP), podem ser melhor abordadas, avaliadas e mensuradas. Assim, a análise de gases expirados através do TCPE pode proporcionar melhor gerenciamento da HP, classificando a capacidade aeróbica e a resposta ventilatória e de troca gasosa nos pacientes com tal distúrbio vascular pulmonar.

Efeitos Agudos da Estimulação Elétrica Funcional e do Treinamento Muscular Inspiratório em Pacientes com Insuficiência Cardíaca: Ensaio Clínico Randomizado Cruzado / Acute Effects of Functional Electrical Stimulation and Inspiratory Muscle Training in Patients With Heart Failure: A Randomized Crossover Clinical Trial

Fundamentos: A insuficiência cardíaca é uma doença multissistêmica que inclui disfunção autonômica. Objetivo: Avaliar os efeitos agudos da Estimulação Elétrica Funcional (EEF) e do Treinamento Muscular Inspiratório (TMI) sobre o controle autonômico, a função endotelial e os níveis de citocinas inflamatórias em pacientes portadores de IC. Métodos: Estudo randomizado cruzado que incluiu 12 pacientes submetidos a três intervenções randomizadas: EEF, TMI, e EEF + TMI, com intervalo de 1 semana entre as sessões. O TMI foi realizado durante 15 minutos, com 30% da pressão inspiratória máxima. A EEF foi realizada nos músculos vasto lateral e vasto medial, a uma frequência de 20Hz durante 30 minutos. O controle autonômico foi medido através de monitorização de pressão batimento por batimento (Finapres); a função endotelial, através da técnica de dilatação mediada por fluxo (DMF); e os níveis de citocinas inflamatórias foram medidos antes e depois de cada sessão. Resultados: O controle autonômico após EEF diminuiu em termos de BF/AF (p=0,01) e BFn.u (p=0,03), e aumentou em termos de RR médio (p=0,005). Observou-se um aumento do RR médio após o TMI (p=0,005) e após EEF+TMI (p=0,02). Não houve diferenças na DMF e na concentração de lactato sérico. Quanto às citocinas, a EEF promoveu uma redução nos níveis de TNF-α (pré versus pós 24 horas, p = 0,05). O TMI resultou em níveis aumentados de IL-10 (pré versus 24 horas pós, p=0,05) e em níveis diminuídos de TNF-α (1 hora pós versus 24 horas pós, p = 0,03). Não houve diferenças quando as duas intervenções foram associadas. Conclusão: EEF, TMI, e EEF + TMI alteraram o controle autonômico, mas não a função endotelial. A EEF e o TMI isoladamente alteraram os níveis de citocinas inflamatórias. Ensaios Clínicos: NCT01325597

Background: Heart Failure is a multisystem disorder, which includes autonomic dysfunction. Objective: To evaluate the acute effects of Functional Electrical Stimulation (FES) and Inspiratory Muscle Training (IMT) on autonomic control, endothelial function and inflammatory cytokine levels in patients with HF. Methods: Randomized crossover trial including 12 patients undergoing three randomized interventions: FES, IMT, and FES+IMT, with a 1-week interval between sessions. IMT was performed for 15 minutes with 30% of the maximal inspiratory pressure. FES was performed in the vastus lateralis and vastus medialis muscles, at 20Hz for 30 minutes. The autonomic control was measured using beat-to-beat blood pressure monitoring (Finapres); the endothelial function, using the flow-mediated dilation technique (FMD); and inflammatory cytokine levels were assessed before and after the sessions. Results: Autonomic control after FES decreased regarding LF/HF (p=0.01) and LFn.u (p=0.03), and increased regarding mean RR (p=0.005). Increased mean RR was observed after IMT (p=0.005) and after FES+IMT (p=0.02). No differences were found in FMD and blood lactate concentration. As regards the cytokines, FES led to a decrease in TNF-α levels (pre vs. 24 hours post, p = 0.05). IMT resulted in increased IL-10 levels (pre vs. 24 hours post, p=0.05) and decreased TNF-α levels (1 hour post vs. 24 hours post, p = 0.03). No difference was observed when the two interventions were associated. Conclusion: FES, IMT, and FES+IMT changed the autonomic control without changing the endothelial function. FES and IMT separately changed inflammatory cytokine levels. Clinical Trials: NCT01325597

Inspiratory muscle training and functional capacity in patients undergoing cardiac surgery

Abstract Introduction: Cardiac surgery is a highly complex procedure which generates worsening of lung function and decreased inspiratory muscle strength. The inspiratory muscle training becomes effective for muscle strengthening and can improve functional capacity. Objective: To investigate the effect of inspiratory muscle training on functional capacity submaximal and inspiratory muscle strength in patients undergoing cardiac surgery. Methods: This is a clinical randomized controlled trial with patients undergoing cardiac surgery at Instituto Nobre de Cardiologia. Patients were divided into two groups: control group and training. Preoperatively, were assessed the maximum inspiratory pressure and the distance covered in a 6-minute walk test. From the third postoperative day, the control group was managed according to the routine of the unit while the training group underwent daily protocol of respiratory muscle training until the day of discharge. Results: 50 patients, 27 (54%) males were included, with a mean age of 56.7±13.9 years. After the analysis, the training group had significant increase in maximum inspiratory pressure (69.5±14.9 vs. 83.1±19.1 cmH2O, P=0.0073) and 6-minute walk test (422.4±102.8 vs. 502.4±112.8 m, P=0.0031). Conclusion: We conclude that inspiratory muscle training was effective in improving functional capacity submaximal and inspiratory muscle strength in this sample of patients undergoing cardiac surgery.

High-Intensity Inspiratory Protocol Increases Heart Rate Variability in Myocardial Revascularization Patients

Abstract Objective: To evaluate heart rate variability during an inspiratory muscle endurance protocol at three different load levels [30%, 60% and 80% of maximal inspiratory pressure], in patients who had previously undergone coronary artery bypass grafting. Methods: Nineteen late postoperative myocardial revascularization patients participating in a cardiovascular rehabilitation program were studied. Maximal inspiratory pressure maneuvers were performed. An inspiratory muscle endurance protocol at 30%, 60% and 80% of maximal inspiratory pressure was applied for four minutes each, in random order. Heart rate and RR intervals were recorded and heart rate variability was analyzed by time (RMSSD-the mean of the standard deviations for all R-R intervals, and RMSM-root-mean square differences of successive R-R intervals) and frequency domains indices (high and low frequency) in normalized units. ANOVA for repeated measurements was used to compare heart rate variability indices and Student t-test was used to compare the maximal inspiratory pressure and maximal expiratory pressure values. Results: Heart rate increased during performance of maximal respiratory pressures maneuvers, and the maximal inspiratory pressure and maximal expiratory pressure mean values were significantly lower than predicted values (P <0.05). RMSSD increased significantly at 80% in relation to rest and 30% of maximal inspiratory pressure and RMSM decreased at 30% and 60% of maximal inspiratory pressure in relation to rest (P <0.05). Additionally, there was significant and progressive decrease in low frequency and increase in high frequency at 30%, 60% and 80% of maximal inspiratory pressure in relation to the resting condition. Conclusion: These results suggest that respiratory muscle training at high intensities can promote greater parasympathetic activity and it may confer important benefits during a rehabilitation program in post-coronary artery bypass grafting.
