Abstract
BACKGROUND Lung cancer significantly impairs exercise capacity and health-related quality of life (HRQL). Pulmonary rehabilitation (PR) has demonstrated positive effects on exercise capacity and HRQL in lung cancer patients. However, its impact on cardiopulmonary function needs further exploration. The aim of this study was to explore the effects of PR on cardiopulmonary function, exercise capacity and HRQL in patients with lung cancer. METHODS Patients with lung cancer were enrolled in a 12-week PR program. Each participant underwent a thorough evaluation, which included spirometry, cardiopulmonary exercise testing, respiratory muscle strength test, and evaluation of HRQL using the Chronic Obstructive Pulmonary Disease Assessment Test (CAT). RESULTS Fifty-six patients completed the PR program. Following PR, exercise capacity significantly improved, as evidenced by increased peak oxygen uptake and work rate (both p < 0.05). Exertional symptoms were notably reduced, including leg soreness and dyspnea at peak exercise, accompanied by a decrease in the CAT score (all p < 0.05). Furthermore, improvements in cardiopulmonary function were observed, encompassing respiratory muscle strength, ventilatory equivalent, tidal volume, stroke volume index, and cardiac index at peak exercise (all p < 0.05). CONCLUSIONS PR demonstrated notable enhancements in cardiopulmonary function, exertional symptoms, exercise capacity, and HRQL in patients with lung cancer.

Abstract
Objectives Asthma is a chronic respiratory disease that affects millions of people worldwide and causes severe symptoms such as wheezing, coughing, and breathing difficulty. Despite modern treatments, 3%-10% of patients develop severe asthma, which requires high-dose medications, and they may still experience frequent and severe symptoms, exacerbations, and psychological impacts. This study aimed to investigate the effects of high-intensity aerobic exercise training (HIAET) in patients with severe asthma. Materials and Methods Patients with severe asthma were recruited, and cardiopulmonary exercise tests, dyspnea, and leg fatigue scores were performed before HIAET. Participants underwent a 12-week hospital-based HIAET, which involved exercising twice weekly to reach 80% of their peak oxygen uptake (VO2). Results Eighteen patients with severe asthma underwent HIAET, which resulted in significant improvement in peak VO2 (1214.0 ± 297.9-1349.4 ± 311.2 mL/min, P = 0.004) and work rate (80.6 ± 21.2-96.2 ± 24.8 watt, P < 0.001) and decrease in dyspnea (5.1 ± 1.8-4.1 ± 1.2, P = 0.017) and fatigue scores (5.2 ± 2.3-4.0 ± 1.2, P = 0.020) at peak exercise. No significant changes were observed in spirometry results, respiratory muscle strength, or circulatory parameters. Conclusion HIAET can lead to improved exercise capacity and reduced dyspnea and fatigue scores at peak exercise without changes in spirometry, respiratory muscle strength, and circulatory parameters.

Evaluation of the relationship of tricuspid regurgitation peak gradient/tricuspid annulus plane systolic excursion to exercise capacity, cardiac index, and ventilatory function during exercise in patients with COPD. Heart Lung 2023; 62:22-27. [PMID: 37295186 DOI: 10.1016/j.hrtlng.2023.05.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2023] [Revised: 05/23/2023] [Accepted: 05/26/2023] [Indexed: 06/12/2023]
Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) often causes cardiopulmonary dysfunction, which deteriorates exercise capacity. Cardiopulmonary exercise testing (CPET) and echocardiography are common tools for evaluating cardiovascular function. No studies have analyzed the correlation between echocardiography-derived parameters and cardiopulmonary response during exercise. OBJECTIVES We analyzed the correlation between echocardiographic parameters such as tricuspid regurgitation peak gradient (TRPG), tricuspid annular plane systolic excursion (TAPSE), TRPG/TAPSE and CPET-derived parameters. METHODS Seventy-seven patients with COPD were evaluated. We analyzed the correlation between parameters derived from echocardiography, exercise capacity, cardiovascular and ventilatory parameters derived from CPET. RESULTS The correlation between TRPG/TAPSE and work rate (WR) was moderate and negative (-0.4423, p = 0.0003), while TRPG had a weak negative correlation with WR (r= -0.3099, p = 0.0127). Oxygen uptake at peak exercise was weakly negatively correlated with TRPG/TAPSE (-0.3404, p = 0.0059), TRPG (r= -0.3123, p = 0.0120), and the ratio of early mitral inflow velocity to early mitral annular diastolic velocity (E/E'). The correlation between TRPG/TAPSE and exercise capacity was higher than that of TPRG, TAPSE, and E/E'. TRPG/TAPSE exhibited a moderate negative correlation with cardiac index, whereas TRPG and TAPSE showed a weak correlation. The correlation between TRPG/TAPSE and cardiac function during exercise was higher than that of TPRG, TAPSE, and E/E'. TRPG/TAPSE, TRPG, TAPSE, and E/E' were weakly negatively correlated with lung function. CONCLUSIONS In assessing exercise capacity, cardiac function, and gas exchange, TRPG/TAPSE proves to be superior to other cardiac parameters. Higher TRPG/TAPSE levels corresponded to lower exercise capacity, cardiovascular and ventilatory function.

Abstract
BACKGROUND Patients with chronic obstructive pulmonary disease (COPD) often have exercise intolerance. The prevalence of hypertension in COPD patients ranges from 39-51%, and β-blockers and amlodipine are commonly used drugs for these patients. OBJECTIVES We aimed to study the impact of β-blockers and amlodipine on cardiopulmonary responses during exercise. METHODS A total 81 patients with COPD were included and the patients underwent spirometry, cardiopulmonary exercise tests, and symptoms questionnaires. RESULTS There were 14 patients who took bisoprolol and 67 patients who did not. Patients with COPD taking ß-blockers had lower blood oxygen concentration (SpO2) and more leg fatigue at peak exercise but similar exercise capacity as compared with patients not taking bisoprolol. There were 18 patients treated with amlodipine and 63 patients without amlodipine. Patients taking amlodipine had higher body weight, lower blood pressure at rest, and lower respiratory rates during peak exercise than those not taking amlodipine. Other cardiopulmonary parameters, such as workload, oxygen consumption at peak exercise, tidal volume at rest or exercise, cardiac index at rest or exercise were not significantly different between patients with or without bisoprolol or amlodipine. Smoking status did not differ between patients with or without bisoprolol or amlodipine. CONCLUSIONS COPD is often accompanied by hypertension, and β-blockers and amlodipine are commonly used antihypertensive drugs for these patients. Patients with COPD taking bisoprolol had lower SpO2 and more leg fatigue during peak exercise. Patients taking amlodipine had lower respiratory rates during exercise than those not taking amlodipine. Exercise capacity, tidal volume, and cardiac index during exercise were similar between patients with and without bisoprolol or amlodipine.

Abstract
Background Chronic obstructive pulmonary disease (COPD) often involves the cardiopulmonary dysfunction that deteriorates health-related quality of life (HRQL) and exercise capacity. Work efficiency (WE) indicates the efficiency of overall oxygen consumption (VO2) during exercise. This study investigated whether different WEs have different effects on pulmonary rehabilitation (PR). Methods Forty-five patients with stable COPD were scheduled for PR. The PR programs consisted of twice-weekly sessions for three months. These patients were comprehensively evaluated by cardiopulmonary exercise testing and COPD assessment test (CAT) before and after PR. We compared these parameters between patients with a normal versus poor WE. Results Twenty-one patients had a normal WE and twenty-four patients had a poor WE (<8.6 mL/min/watt). Patients with a poor WE had earlier anaerobic metabolism, a poorer oxygen pulse, lower exercise capacity, more exertional dyspnea, and a poorer HRQL than those with a normal WE. PR improved exercise capacity, HRQL, anaerobic threshold, exertional dyspnea and leg fatigue in patients with either normal or poor WE. However, significant improvement of WE, oxygen pulse, respiratory frequency (Rf) during exercise, chest tightness, activity and sleepiness by CAT were noted only in patients with a poor WE. Among the patients with a poor WE, 29% patients had WE returned to normal after PR. Conclusion Patients with different WE had different responses to PR. PR improved exercise capacity and HRQL regardless of a normal or poor WE. However, WE, oxygen pulse, Rf during exercise, chest tightness, activity and sleepiness were only improved in patients with a poor WE.

Abstract
Background Pulmonary hypertension (PH) is a frequent complication in patients with COPD. Objective To determine if, in patients with COPD, the presence of PH decreases exercise tolerance. Methods We included studies that analysed exercise tolerance using a cardiopulmonary exercise test (CPET) in patients with COPD with PH (COPD-PH) and without PH (COPD-nonPH). Two independent reviewers analysed the studies, extracted the data and assessed the quality of the evidence. Results Of the 4915 articles initially identified, seven reported 257 patients with COPD-PH and 404 patients with COPD-nonPH. The COPD-PH group showed differences in peak oxygen consumption (V′O2peak), −3.09 mL·kg−1·min−1 (95% CI −4.74 to −1.43, p=0.0003); maximum workload (Wmax), −20.5 W (95% CI −34.4 to −6.5, p=0.004); and oxygen pulse (O2 pulse), −1.24 mL·beat−1 (95% CI −2.40 to −0.09, p=0.03), in comparison to the group with COPD-nonPH. If we excluded studies with lung transplant candidates, the sensitivity analyses showed even bigger differences: V′O2, −4.26 mL·min−1·kg−1 (95% CI −5.50 to −3.02 mL·kg−1·min−1, p<0.00001); Wmax, −26.6 W (95% CI −32.1 to −21.1 W, p<0.00001); and O2 pulse, −2.04 mL·beat−1 (95% CI −2.92 to −1.15 mL·beat−1, p<0.0001). Conclusion Exercise tolerance was significantly lower in patients with COPD-PH than in patients with COPD-nonPH, particularly in nontransplant candidates. The V′O2peak, Wmax and O2 pulse values were significantly lower in patients with COPD-PH than in patients with COPD-nonPH, particularly in nontransplant candidateshttps://bit.ly/3s5dtJ9

Poor Work Efficiency is Associated with Poor Exercise Capacity and Health-Related Quality of Life in Patients with Chronic Obstructive Pulmonary Disease. Int J Chron Obstruct Pulmon Dis 2021; 16:245-256.

Abstract
Introduction Chronic obstructive pulmonary disease (COPD) is a progressive disease with deteriorating cardiopulmonary function that decreases the health-related quality of life (HRQL) and exercise capacity. Patients with COPD often have cardiovascular and muscular problems that hinder oxygen uptake by peripheral tissues, resulting in poor oxygen consumption efficiency. It is important to develop new physiological parameters to evaluate oxygen consumption efficiency during activities and to evaluate its association with exercise capacity and HRQL. Work efficiency (WE) measures oxygen consumption efficiency during exercise. We hypothesize that patients with poor WE should have exercise intolerance and poor HRQL. Therefore, we aimed to evaluate the association between WE and exercise capacity, HRQL and other cardiopulmonary parameters. Patients and Methods Seventy-eight patients with COPD were evaluated with spirometry, cardiopulmonary exercise testing, and assessment of dyspnea score and HRQL (using the St. George’s Respiratory Questionnaire [SGRQ]). Cardiopulmonary exercise testing was performed using a cycle ergometer with an incremental protocol and exhaled breath analysis to assess oxygen consumption. WE was defined as the relationship between oxygen consumption and workload. Results There were 31 patients with normal WE (group I) and 47 patients (group II) with poor WE. Patients with poor WE had lower exercise capacity (maximal oxygen consumption, group I vs II as 1050±53 vs 845 ±34 mL/min, p=0.0011), poorer HRQL (SGRQ score 41.1±3.0 vs 55±2.2, p=0.0002), higher exertional dyspnea score (5.1±0.2 vs 6.1±0.2, p= 0.0034) and early anaerobic metabolism during exercise (anaerobic threshold, 672±27 vs 583 ±18 mL/min, p=0.0052). Conclusion WE is associated with exercise capacity and HRQL. Here, patients with poor WE also had exercise intolerance, poorer HRQL, and more exertional dyspnea.

Abstract
Patients with nontuberculous mycobacterial lung disease (NTM-LD) often have significant exercise intolerance and poorer health-related quality of life (HRQL). The goals of treatment for NTM-LD should include reducing the severity of symptoms, improving HRQL, and reducing acute exacerbations. Nonpharmacological treatment, including pulmonary rehabilitation program and optimal nutritional strategy, should be one part of treatment for NTM-LD. A pulmonary rehabilitation (PR) program can comprise education, airway clearance techniques instruction, exercise training program, and inspiratory muscle training (IMT). Airway clearance techniques can improve the volume of sputum expectorated, cough symptom, breathlessness, and HRQL. Exercise training can improve exercise capacity and HRQL, and reduce acute exacerbations and dyspnea. Clinical benefits of IMT remain controversial but high-intensity IMT has been shown to be effective in increasing respiratory muscle strength with concurrent improvement of HRQL and exercise capacity. Body weight and muscle mass loss are common in patients with NTM-LD. An adequate protein and caloric diet combined with antioxidant nutrients might be the most appropriate dietary strategy. Comprehensive treatment for NTM-LD should include the combination of both pharmacological and nonpharmacological treatments. The management programs should be tailored to the individual's condition.

Exercise training increases respiratory muscle strength and exercise capacity in patients with chronic obstructive pulmonary disease and respiratory muscle weakness. Heart Lung 2020; 49:556-563. [PMID: 32199677 DOI: 10.1016/j.hrtlng.2020.03.005] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2019] [Revised: 03/04/2020] [Accepted: 03/06/2020] [Indexed: 10/24/2022]
Abstract
BACKGROUND How respiratory muscle strength influences the effectiveness of pulmonary rehabilitation (PR) in patients with chronic obstructive pulmonary disease (COPD) is unclear. OBJECTIVE To investigate the benefits of PR in subjects with COPD according to respiratory muscle strength. METHODS Ninety-seven subjects with COPD were evaluated using maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), pulmonary function tests, the cardiopulmonary exercise test (CPET), and the St. George's Respiratory Questionnaire (SGRQ). Subjects were divided into four groups: 1 (normal MIP and MEP); 2 (low MIP); 3 (low MEP); and 4 (low MIP and MEP). Subjects underwent PR for 3 months; MIP, MEP, SGRQ, and CPET were evaluated post-PR. RESULTS Subjects with both poor MIP and MEP had the highest dyspnea score, lowest exercise capacity, and poorest health-related quality of life (HRQoL). PR improved exercise capacity and HRQoL in all groups, with more improvement in MIP, MEP, tidal volume (on exercise), and dyspnea (at rest) in subjects with both low MIP and MEP. CONCLUSIONS Patients with respiratory muscle weakness had worse dyspnea, lower exercise capacity, and poorer HRQoL at baseline. Exercise training improved respiratory muscle strength with concurrent improvement of exercise capacity, HRQoL, and dyspnea score. Subjects with both poor baseline MIP and MEP showed greater benefits of PR.
