Full textBACKGROUNG: It has been described that patients with chronic heart failure (CHF) may present with dynamic reduction in inspiratory capacity (IC), which was associated with low peak aerobic capacity. Little information is currently available about whether this reduction is related to respiratory mechanics abnormalities or to impaired inspiratory muscle function. OBJECTIVE: To compare inspiratory muscle activity and intensity of dyspnea during exercise in stable patients with CHF presenting (Group 1) or not (Group 2) with dynamic reduction in IC. METHODS: We studied 16 clinically stable, non obese patients with CHF (11 males, 30 ± 5% ejection fraction) treated according to current evidence-based guidelines with no other systemic diseases or spirometric evidence of airflow obstruction (FEV1/FVC = 83 ± 5%). They performed incremental cardiopulmonary cycle exercise test with serial measurements of IC, dyspnea rating (Borg), and continuous monitoring of esophageal (Pes) and gastric (Pga) pressures. Transdiaphragmatic pressure (Pdi) was obtained from Pga–Pes. Sniff and maximal inspiratory pressure (MIP) maneuvers were compared at rest and immediately post exercise. RESULTS: Four patients (25%, Group 1) showed IC reduction during exercise (-0.18 ± 0.02 vs 0.28 ± 0.19L; p<0.05). There were no significant between-groups differences in lung function and echocardiographic variables, except for a lower functional residual capacity (72 ± 9 vs 97 ± 17%; p < 0.05) in Group 1 and a lower MIP (-101 ± 25 vs 67 ± 24 cm H2O; p < 0.05) in Group 2. Pes,Sniff (Group 1: -77.9 ± 8.7 to -79.6 ± 8.8; Group 2: -63.3 ± 4.8 to -66.3 ± 3.8 cmH2O) and Pdi,Sniff (Group 1: 116.3 ± 13.9 to 118.3 ± 14.2; Group 2: 92.3 ± 5.6 to 98.0 ± 6.0 cmH2O) did not significantly decrease with exercise. Despite Pga and Pdi felt along successive IC maneuvers in Group 1, Pes did not differ between groups. Dyspnea was also similar between groups. Finally, inspiratory reserve volume was lower in Group 1 only at peak exercise (0.90 ± 0.08 vs 1.47 ± 0.21L; p <0.05). CONCLUSIONS: Decrements in exercise IC in some patients with CHF seems accompanied by a dynamic impairment in diaphragm strength that is fully compensated by other inspiratory rib cage muscles. Group 1 presented similar dyspnea compared to Group 2 probably because they stopped exercise before reaching critical ventilatory constraints to tidal volume expansion.

Full textRationale: The exercise induced inspiratory capacity (IC) reduction observed in some patients with pulmonary arterial hypertension (PAH) could potentially be influenced by respiratory muscle dysfunction. Aims: To investigate if there is any relationship between IC and respiratory muscle strength before and after maximal exercise and to study the contribution of respiratory muscle pressure and IC in exercise dyspnea and capacity in PAH patients. Methods: 27 patients with PAH and 12 healthy matched controls were compared. All participants underwent cardiopulmonary exercise test (CPET) with serial IC measurements. Inspiratory and expiratory maximal mouth pressure (PImax and PEmax, respectively) were measured before and at peak/post exercise. Results: Patients had lower forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC) (with similar FEV1/FVC ratio) and peak aerobic capacity and higher exercise dyspnea. PImax and PEmax were significantly lower in PAH patients compared to controls. However, post exercise variations from rest were not significant different in either group. Patients presented significant rest-to-peak reduction in IC compared to controls. 17/27 patients (63%) exhibited IC reduction during exercise. Considering only patients, there was no association between IC and PImax or PEmax (pre, post exercise or change from rest). Comparing patients with and without IC reduction, there was no difference in the proportion of patients presenting inspiratory (41 vs 44%) or expiratory (76 vs 89%) pressure reduction after exercise, respectively. In the same way, no difference in both inspiratory and expiratory respiratory pressure change with exercise was observed comparing these subgroups. Conclusions: In summary, respiratory muscle strength was significantly lower in PAH patients compared to controls and a significant proportion of PAH presented IC reduction during exercise. Nonetheless, no associations between IC and respiratory muscle strength changes with exercise were observed, suggesting a true dynamic lung hyperinflation. Additionally, the only parameter associated with exercise induced dyspnea was resting IC and with peak aerobic capacity was the magnitude of PEmax reduction after exercise.

Full textBACKGROUND: The mechanical disadvantage induced by hyperinflation forces chronic obstructive pulmonary disease (COPD) patients to use their accessory respiratory muscles. In COPD patients the effects of applying stretching techniques to these muscles are not well understood. AIM: The aims of our study were: a) to compare the activation of accessory respiratory muscles in patients with COPD and control subjects and study the relationship between muscle activation and inspiratory capacity (IC); b) to analyze the effects of a proprioceptive neuromuscular facilitation (PNF) stretching technique applied to the accessory respiratory muscles on patients with COPD. METHODS: We studied 30 male COPD and 30 control subjects. All subjects underwent spirometry, measurement of maximal inspiratory and expiratory pressures (MIP, MEP) and assessment of muscle activation by surface electromyography (sEMG). COPD patients were randomized for PNF of accessory respiratory muscles or isometric contraction of the biceps (sham treatment; ST). Mean forced vital capacity (FVC), IC, MIP, MEP, pulse oximetry (SpO2) and thoracic expansion were measured before and after intervention. RESULTS: Baseline values of COPD patients were: FVC 2.69 ± 0.6 l, FEV1 1.07 ± 0.23 l (34.9 ± 8.2%), IC 2.25 ± 0.5l, PImax -71.8 ± 19.8 cmH2O and PEmax 106.1 ± 29.9 cmH2O. Control subjects had all baseline values normal. Patients with COPD showed higher activation of both scalene and right intercostal muscles at rest and of left intercostal and left scalene muscle during the IC maneuver (p <0.05). Moderate correlation was observed between CI and the right sternocleidomastoid muscle activity (r = -0.41, p = 0.026) and left scalene (r = -0.40, p = 0.031) in patients with COPD. No association was observed in the control group. CI varied (OCI) 0.083 ± 0.04 l after PNF and -0.029 ± 0.015 l after ST (p = 0.03). The MEP increased from 102.4 ± 20.6 to 112.4 ± 24.5 cmH2O (p = 0.02) after PNF and did not change significantly after TS. There was a significant increase in the SpO2 with PNF (p=0.02). There was no change in FVC, MIP or thoracic mobility after PNF. There was no change in EMG after PNF or TS. CONCLUSIONS: Our results showed that patients with COPD have greater activation of accessory respiratory muscles at rest and during CI compared with controls, and that this activation is inversely associated with CI. Our study also demonstrated that a session of PNF applied to the accessory respiratory muscles in patients with COPD increased CI, MEP and SpO2, with no change in the sEMG signal. Additional studies are needed to evaluate the long-term effects of PNF applied to the acessory respiratory muscles on patients with COPD.

Full textPatients with heart failure (HF) may show weakness of respiratory muscles. The inspiratory muscle training (IMT) has been used in this population to improve cardiorespiratory fitness, however, does not know the safety and hemodynamic changes that may occur during a session of exercise model. Therefore, our objective was to evaluate the cardiovascular response during acute inspiratory muscle exercise (AIME) in patients with HF associated with hypertensive cardiomyopathy (HCM) or Chagas (CCM). Initially, the patients responded to the questionnaire of quality of life of Minnesota and the test sequence performed by respiratory muscle strength equipment MVD300 digital manometer. Those patients who had inspiratory muscle weakness (values 70% predicted maximal inspiratory pressure - MIP) were AIME. During the basal (resting) and AIME recorded indirectly and non-invasive blood pressure curves (BP) beat to beat with the equipment Finometer. We also monitor the heart rate by electrocardiogram and respiration using the respiratory belt. The protocol was performed with patients sitting and lasted 25 minutes (10 min baseline, 10 min AIME and 5 min recovery). The exercise was carried out with the equipment inspiratory threshold load of 30% of MIP. The protocol of the AIME was performed for 27 patients with HCM and 9 patients with CCM (LVEF <45%), however, seven patients (26%) in group HCM not finalized the protocol for having elevated systolic BP 20mmHg and refer exhaustion. All patients in CCM group completed the scheduled time of the AIME, but reported heavy fatigue at the end of the exercise. When comparing the basal. vs. exercise (value ) for both groups (HCM and CCM), we found significant increases in: Systolic BP ( = 9 ± 2 e = 7,6 ± 3 mmHg), diastolic BP ( = 4,8 ± 1 e = 4,2 ± 1 mmHg), HR ( = 5,5 ± 1,2 e = 6,6 ± 3 bpm) e PD ( = 1327 ± 208 e = 1319 ± 373 mmHg.bpm); the HCM group also showed a significant increase in CO ( = 0,36 ± 0,1 l/min), CI ( = 0,2 ± 0,1 l/min/m2), dp/dt ( = 118 ± 35 mmHg/s) e SPTI ( = 1,98 ± 0,6 mmHg.s). The autonomic modulation was similar in both groups at baseline and during exercise there was an increase in vagal modulation in the group HCM ( = 258 ± 115 ms2). Our results demonstrate that the AIME caused significant hemodynamic changes in patients of both groups, but no clinical significance in most areas. A quarter (26%) patients with HCM showed exacerbated response of SBP, reported exhaustion and therefore could not perform the predetermined time (10 min) of the AIME. Thus, we conclude that before the indications of IMT (3 x 10 min / day) is necessary to carry out an exercise session with cardiac and respiratory monitoring, to evaluate whether or not the security alert to this type of exercise patients with HF of different etiologies

Resumo: As medidas da PImáx e PEmáx são utilizadas para avaliar a força da musculatura respiratória. Porém, o efeito da posição corporal sobre essas medidas não se encontra bem estabelecido na literatura. O objetivo deste estudo foi avaliar a influência de diversas posições corporais nos valores da PImáx e PEmáx. MÉTODO: Foi realizado um estudo prospectivo e aberto, em que foram avaliados 50 indivíduos saudáveis (25 homens e 25 mulheres), com idade entre 18 e 55 anos, em sete diferentes decúbitos [sentado (PRE), Trendelenburg (TREND), prona, 0°, decúbitos lateral direito (DLD) e esquerdo (DLE) e 45°]. Foram também analisadas as influências do sexo sobre essas variáveis. RESULTADOS: O maior valor da PImáx (média ± DP) foi de -79,4 ± 21,7 cmH2O em 45° nas mulheres e de -82,8 ± 21,3 cmH2O em DLD no homem (p = NS) e o menor em TREND (-64,3 ± 21,6 cmH2O versus -79,1 ± 22,3 cmH2O; p < 0,05). Com relação à PEmáx todos os valores no sexo masculino foram maiores que no feminino (p < 0,0001), sem influência da posição corporal. CONCLUSÕES: Determinadas posições corporais e o sexo influenciaram nas medidas de PImáx. Com relação às medidas da PEmáx, apenas a influência do sexo foi significativa
Abstract: Measurements of PImax and PEmax are useful to evaluate respiratory muscle strength. However, the effects of body position on these variables are not well established in the literature. The objective if this study was to evaluate the influence of different body positions on PImax and PEmax values. METHODS: Prospective, open label study, in which 50 adult healthy volunteers (25 males e 25 females), aging 18-55 years, were evaluated in seven different positions: sitting (PRE), Trendelenburg (TREND), prone, 0°, right lateral (RLD) and left lateral (LLD) decubitus and 45°. The influence of gender on these variables was also analyzed. RESULTS: The greatest Plmax value (mean ± SD) was -79.4 ± 21.7 cmH2O at 45° in females and -82.8 ± 21.3 cmH2O at RDL in males (p=NS) and the smallest at TREND (-64,3 ± 21.6 cmH2O versus -79.1 ± 22,3 cmH2O; p<0.05). PEmax values were ever greater in males than in females (p < 0.0001), without influence of body position. CONCLUSIONS: In adult healthy volunteers, some body positions and gender have had significant influence on PImax values. Otherwise, PEmax values have been influenced only by gender.

Patients with Chronic Obstructive Pulmonary Disease (COPD) have reduced diaphragmatic mobility (DM) and ventilatory reserve (VR). DM has demonstrated relationship with lung function, air trapping, lung hyperinflation, distance covered on the six-minute walk test (6MWT), mortality and dyspnea in patients with COPD. Similarly, VR is correlated with exercise capacity, disease severity and dyspnea. However, there are no studies investigating whether static hyperinflation and VR influence DM in patients with COPD. Objective: To investigate the influence of static hyperinflation and VR on DM in patients with COPD, as well as to compare the anthropometric characteristics, spirometric data, DM, dyspnea and submaximal exercise capacity among VR> 11l / minute (l / min) and VR <11l / min groups. Methods: This is a cross-sectional study that evaluated 42 patients with COPD. On the first day, patients underwent the following assessments: anthropometry, vital signs, spirometry and dyspnea. On the second day, patients performed the six-minute walk test and after one week, DM was evaluated by radiographic method considering the distance between maximal inspiration and expiration (DMdist). The sample was divided into VR > 11l / min and VR <11l / min groups for the comparison of anthropometric characteristics, spirometric data, DM, dyspnea and submaximal exercise capacity. Statistical analysis: Data normality was tested by Shapiro Wilk. According to data distribution, parametric or nonparametric test was used. Simple linear regression found the influence of lung hyperinflation and VR on DM. The Pearson s linear correlation coefficient correlated DM with static hyperinflation and VR. The t test for independent samples or the Mann Whitney U test was used to compare VR> 11l / min and VR <11l / min groups. Significance level of 5% (p <0.05). Results: Static hyperinflation influenced DM by 46%, i.e., to increase 1 liter in inspiratory capacity (IC), DM increased 1.56 cm (p 0.001, F = 34.55), while VR influenced only 25%, and for every increase of 1 l / min of VR, DM increased by 0.38 mm (p = 0.001, F =13.78). By comparing VR >11l / min and VR < 11l / min groups, it was found that in the VR <11l / min group, patients were older (69 ± 5 versus 61 ± 8 years) and showed reduction in the following variables: IC, forced expiratory volume in the first second (FEV1), DM, worse submaximal exercise capacity and increased dyspnea. Conclusions: Static hyperinflation and VR influence DM. However, hyperinflation exerts greater influence on DM compared to VR. In addition, patients with COPD who have VR <11l / min are more committed both in the lung function and DM as in submaximal exercise capacity and dyspnea when compared to patients with COPD with who have VR> 11l / min.
Pacientes com doença pulmonar obstrutiva crônica (DPOC) apresentam redução da mobilidade diafragmática (MD) e da reserva ventilatória (RV). A MD tem demonstrado relação com a função pulmonar, aprisionamento de ar, hiperinsuflação pulmonar, distância percorrida no teste da caminhada de seis minutos (TC6min), mortalidade e dispneia em pacientes com DPOC. Da mesma forma, a RV apresenta relação com a capacidade de exercício, gravidade da doença e dispneia. Contudo não há estudos que investiguem se a RV influencia a MD em pacientes com DPOC. Objetivo: Investigar a influência da RV na MD em pacientes com DPOC, bem como comparar as características antropométricas, função pulmonar, MD, dispneia e capacidade de exercício entre os grupos RV >11litros/minuto (l/min) e RV <11l/min. Métodos: Tratou-se de um estudo com delineamento transversal, no qual foram avaliados 42 pacientes com DPOC de ambos os sexos e idade média de 64±8 anos. No primeiro dia, os pacientes foram submetidos às seguintes avaliações: antropometria, sinais vitais, espirometria e dispneia. No segundo dia foram submetidos ao TC6min, e após uma semana foi avaliada a MD pelo método radiográfico da distância entre a inspiração e expiração máxima (MDdist). A amostra foi subdividida nos grupos RV >11l/min e RV <11l/min para comparação das características antropométricas, dados espirométricos, MD, dispneia e capacidade submáxima de exercício. Análise estatística: A normalidade dos dados foi testada pelo teste de Shapiro Wilk. Conforme a distribuição dos dados utilizou-se um teste paramétrico ou não paramétrico. O coeficiente de correlação linear de Pearson correlacionou a RV com a MD. O teste de regressão linear simples verificou a influência da RV na MD. O teste t de Student para amostras independentes ou o teste U de Mann Whitney foi usado para comparação dos grupos RV >11l/min e RV <11l/min. Adotou-se nível de significância de 5% (p < 0,05). Resultados: A RV influenciou em 25% a MD, sendo que para cada aumento de 1 l/min da RV, a MD aumentou em 0,38 mm (p=0,001, F=13,78). Ao comparar os grupos RV ˃ 11l/min e RV ˂ 11l/min, constatou-se que no grupo RV ˂11l/min os pacientes eram mais idosos (69±5 versus 61±8 anos) e apresentaram menores valores das variáveis: CI, volume expiratório forçado no primeiro segundo (VEF1), MD, pior capacidade submáxima de exercício e maior dispneia. Conclusões: A RV influencia a MD. Além disso, pacientes com DPOC que apresentaram RV <11l/min são mais comprometidos tanto na função pulmonar e MD quanto na capacidade submáxima de exercício e dispneia, em comparação a pacientes com DPOC que apresentam RV >11l/min.

Full textIntroduction: The application of expiratory positive aiway pressure (EPAP) in COPD patients during exercise may reduce dynamic hyperinflation (DH), and consequently dyspnea, while, on the other hand, can increase the resistive work of breathing. Therefore, the objective of the current study was to evaluate the effects of two intensities of EPAP on inspiratory capacity, dyspnea and exercise tolerance in patients with moderate to very-severe COPD. Methods: Cross-sectional, experimental, 4-visit study. In the Visit 1, participants performed symptom-limited cycling incremental cardiopulmonary exercise test (CPET). In Visits 2-4, at least 48hrs apart, in a randomized order, they performed constant CPET (ctCPET) without EPAP, EPAP with 5cmH2O (EPAP5), or EPAP with 10cmH2O (EPAP10). Results: The study included 15 non-hypoxemic subjects ranging from moderate-to-very-severe COPD (mean FEV1=35.3 ± 10.9% of predicted). Successive intensities of EPAP during ctCPET tended to cause a progressive reduction in exercise tolerance (p=0.11). Of note, 10 of 15 presented shorter exercise duration when EPAP10 was compared to the test without EPAP (-151±105s, p<0.01 or -41±26%). Moreover, significant constraint to minute-ventilation, at expenses of limited tidal volume expansion, was observed with EPAP (p<0.05). Finally, dyspnea sensation and IC measurements were similar during exercise among the interventions. Conclusion: Progressive levels of EPAP during exercise tented to cause a progressive reduction in exercise tolerance in COPD patients without improvement in exercise dyspnea and DH.
