The role of cardiopulmonary rehabilitation in the recovery of right ventricular function and right ventricular-pulmonary artery coupling in convalescent COVID-19 patients

Abstract Introduction Coronavirus disease-19 (COVID-19) is predominantly a respiratory disease, but simultaneous cardiovascular impairment has been documented, even in the post-acute phase. Subclinical right ventricular (RV) dysfunction is often described and mainly attributed to parenchymal lung damage (ARDS) or pulmonary vascular complications such as pulmonary embolism. Cardiopulmonary rehabilitation programs play an integral part in the long-term management of chronic cardiovascular and pulmonary diseases and lately have been proven useful in managing post-COVID-19 sequelae. Purpose The aim of this study is to assess the impact of a post-COVID-19 rehabilitation program in the recovery of right ventricular function and right ventricular-pulmonary artery coupling in convalescent COVID-19 patients. Methods 40 convalescent COVID-19 patients were evaluated one and three months after the acute phase of the disease. 30 subjects participated in a 3-month cardiopulmonary rehabilitation program (study group) and 10 did not (control group). Right ventricular function echocardiographic parameters (right ventricular global longitudinal strain (RVGLS) and pulmonary artery systolic pressure (PASP)) were evaluated and right ventricular-arterial coupling (RVAC) was estimated via the RVGLS/PASP ratio. Results A total of 40 patients were included in this study, of whom 30 underwent cardiopulmonary rehabilitation. There were no major differences in the prevalence of cardiovascular risk factors between the two groups. When examining right ventricular parameters at baseline, RVGLS (Rehabilitation: -23.1 (4.1) % vs. No rehabilitation: -23.0 (4.7) %, p=0.94) and PASP (Rehabilitation: 28 (6) mmHg vs. No rehabilitation: 25 (4) mmHg, p=0.08) did not differ statistically between the two groups. RVAC was also similar at baseline (Rehabilitation: -0.96 (0.28) %/mmHg vs. No rehabilitation: -0.86 (0.27) %/mmHg, p=0.30). At follow-up, patients who underwent cardiopulmonary rehabilitation exhibited a significant improvement in RVGLS (from Τ0: -23.1 (4.2) % to T1: -24.3 (4) %, p<0.001), PASP (from T0: 28 (6) mmHg to T1: 27 (5) mmHg, p=0.016), and RVAC (from T0: -0.86 (0.27) %/mmHg to T1: -0.93 (0.26) %/mmHg, p<0.001). In the no rehabilitation group, RVGLS (from T0: -23.0 (4.7) % to T1: -23.2 (4.4) %, p=0.19), PASP (from T0: 25 (4) mmHg to T1: 25 (4) mmHg, p=0.17), and RVAC (from T0: -0.96 (0.28) %/mmHg to T1: -0.96 (0.27) %/mmHg, p=0.60) were not significantly altered at follow-up. We detected a statistically significant interaction of intervention with RVGLS (p=0.024) and RVAC (p=0.012) (Figure 1). Conclusion Subclinical right ventricular dysfunction is present in convalescent COVID-19 patients. Cardiopulmonary rehabilitation can accelerate the improvement of RVAC by mediating both the RV afterload reduction (PASP) and improving RV function.Figure 1

The Effect of a Rehabilitation Program Accompanied by Karo-Proketic to Rehabilitate the Injury of Minor Rupture of The Rectus Muscles in The Lumbar Region for Sitting Volleyball Players

The aim of this study was to examine whether or not a cardiopulmonary rehabilitation program is effective in treating rectus muscle injuries in the lumbar region among volleyball players who have a tendency to sit for extended periods of time due to their sport. Pre- and post-tests were administered to the same group of volunteers who participated in this research. The study was an experiment. An experimental approach was used in the design of the investigation. At the sports competition that took place in 2024-2025, the individuals who took part in this research were members of the disabled sitting volleyball team that participated for the Anbar governorate. This analysis was carried out with the help of the SPSS software. According to the findings, the player's ability to bend forward and backward was significantly improved as a consequence of the rehabilitation exercises that were carried out. In the lumbar region, those people who had partial rips in the rectus muscle improved greatly from this practice. As a result of this, the researchers came up with the recommendation that these exercises should be maintained in order to either prevent new injuries from occurring or to improve ailments that were already existing.

Comparison of exercise capacity and physical activity in patients with hyperthyroidism and controls

BackgroundHyperthyroidism impairs muscle mitochondrial metabolism and destroys many body systems. However, information is limited on how much physical and physiological outcomes are impaired in patients with newly diagnosed hyperthyroidism (NDH) and euthyroid. The comparison of pulmonary function, functional exercise capacity, respiratory muscle strength and endurance, physical activity levels (PAL), dyspnea, and quality of life (QoL) in patients and healthy controls was aimed. MethodSixteen patients with hyperthyroidism (evaluated twice at new diagnosis and euthyroid state) and healthy controls were compared. Pulmonary function was evaluated with a spirometer, functional exercise capacity with a 6-min walking test (6-MWT), respiratory muscle strength with a mouth pressure device and endurance with threshold loading test, PAL with metabolic holter, dyspnea with Modified Medical Research Council (MMRC) scale, and QoL with Quality of Life in Thyroid Patients Scale (ThyPRO). ResultsSix-MWT distance and respiratory muscle endurance significantly decreased, and MMRC dyspnea scale and ThyPRO scores were higher in patients with NDH and euthyroid compared to controls (p < 0.05). In addition, maximum inspiratory pressure and maximum expiratory pressure significantly decreased in patients with NDH compared to controls, and PAL was less active according to the number of steps in euthyroid patients (p < 0.05). The pulmonary function test was similar in both groups (p > 0.05). ConclusionExercise capacity, respiratory muscle strength and endurance, PAL, dyspnea, and QoL were affected in patients. Patients with hyperthyroidism should be evaluated at the onset of diagnosis, followed up, and referred to cardiopulmonary rehabilitation programs at the earliest. ClinicalTrials number: NCT04825964.

The Impact of Cardiopulmonary Rehabilitation on Ventriculoarterial Coupling in Post-Coronavirus Disease-2019 Patients.

Coronavirus disease-2019 (COVID-19) affects the cardiovascular system even after the acute phase of the disease. Cardiopulmonary rehabilitation may improve post-COVID-19 symptoms. This study aims to evaluate the impact of a cardiopulmonary rehabilitation program after acute COVID-19 on arterial stiffness, left ventricular function, and ventriculoarterial coupling (VAC). Forty-eight adults were examined 1 (T0) and 3-mo (T1) following recovery from COVID-19 and randomized 1:1 to participate or not in a 3-mo rehabilitation program. Matched subjects were enrolled as a non-COVID-19 group. Arterial stiffness was evaluated by carotid-femoral pulse wave velocity (PWV). Left ventricular (LV) systolic performance was evaluated with global longitudinal strain (GLS). The PWV/LV-GLS ratio was calculated as an index of VAC. High-sensitivity C reactive protein (hs-CRP) was measured. At T0, convalescent patients with COVID-19 had impaired PWV ( P =.001) and reduced VAC ( P =.001) compared to non-COVID-19 subjects. PWV (8.15±1.37 to 6.55±0.98 m/sec, P <.001) and LV-GLS (-19.67±1.98 to-21.3±1.93%, P <.001) improved only in convalescent patients with COVID-19 undergoing rehabilitation. Similarly, VAC was only improved in the rehabilitation group (-0.42±0.11 to-0.31±0.06 m·sec -1 ·% -1 , P <.001). A significant improvement in VO 2max was noted after rehabilitation (15.70 [13.05, 21.45] to 18.30 [13.95, 23.75] ml· kg -1 ·min -1 , P =.01). Finally, hs-CRP was improved in both groups with a significantly greater improvement in the rehabilitation group. A 3-mo rehabilitation program in convalesced patients with COVID-19 enhances the recovery of arterial stiffness, left ventricular function, and VAC, highlighting the beneficial mechanisms of rehabilitation in this patient population.

Effects of Cardiopulmonary Rehabilitation on Cardiorespiratory Fitness and Clinical Symptom Burden in Long COVID: Results from the COVID-Rehab Randomized Controlled Trial.

To investigate the effectiveness of an eight-week cardiopulmonary rehabilitation program on cardiorespiratory fitness (VO2peak) and key cardiopulmonary exercise test measures, quality of life, and symptom burden in individuals with Long COVID. Forty individuals with Long COVID (mean age 53 ± 11 years), were randomized into 2 groups: 1/ Rehabilitation group: centre-based individualized clinical rehabilitation program (8 weeks, 3 sessions per week of aerobic and resistance exercises, and daily inspiratory muscle training) and 2/ Control group: individuals maintained their daily habits during an eight-week period. There was a significant difference between groups in mean VO2peak improvement (p = 0.003). VO2peak improved significantly in the rehab group (+2.7 mL.kg.min 95%IC:+1.6 to +3.8 p < 0.001) compared to the control group (+0.3 mL.kg.min 95%IC:-0.8 to +1.3 p = 0.596), along withVE/VCO2 slope (p = 0.032) (-2.4 95%IC:-4.8 to +0.01 p = 0.049 and + 1.3 95%IC:-1.0 to +3.6 p = 0.272 respectively) and VO2 at first ventilatory threshold (p = 0.045). Furthermore, all symptom impact scales improved significantly in the rehabilitation group compared to the control group (p < 0.05). An individualized and supervised cardiopulmonary rehabilitation program was effective in improving cardiorespiratory fitness, ventilatory efficiency, and symptom burden in individuals with Long COVID. Careful monitoring of symptoms is important to appropriately tailor and adjust rehabilitation sessions.

Rehabilitation of cardiological patients with post-COVID syndrome: morphofunctional data report

INTRODUCTION. Post-COVID is a common complication of COVID-19, occurring in more than a third of patients, and condition will persist for more than 3 months after infection with the SARS-CoV-2. AIM. To evaluate impact and potential effectiveness of a comprehensive physical rehabilitation program on health of cardiac patients with complications of a previously suffered new coronavirus infection SARS-CoV-2 COVID-19. MATERIALS AND METHODS. The study involved 128 cardiology patients with post-COVID syndrome. The study participants comprised three groups depending on the 12-week physical rehabilitation program. The effectiveness of rehabilitation was assessed through parameters of cardiopulmonary testing, as well as the 6-minute walk exercise test and the degree of dyspnea according to modified mMRC dyspnea questionnaire. RESULTS. The mMCR index in CPR group was 1.0 [0.0–1.0] point, compared with 2.0 [1.0–2.0] in control and comparative groups (p 0.05); exercise tolerance VO2max increased by 8.3 ± 3.8 % (p 0.05); normalization of heart rate and blood pressure in response to physical activity after 12 weeks in intervention group was 5.0 ± 2.1 % compared to comparative and control groups; 6MWT test results 688 m, in the intervention group, versus 490 m, for participants in control group (p 0.05). DISCUSSION. A comparative analysis of previously conducted studies confirmed pattern between the inclusion of combined cardiorespiratory training in the protocol for 12-week rehabilitation of post-COVID complications among cardiac patients, and a decrease in the degree of shortness of breath, as well as an increase in exercise tolerance. CONCLUSIONS. Based on experimental data obtained, it is advisable to analyze the effects of Cardiopulmonary Physical Rehabilitation program in the framework of larger randomized clinical trials. This will allow a more detailed assessment of the clinical consequences, as well as the ability to adjust mode and dose of physical activity of proposed rehabilitation program.

Physical functional recovery in the early period after hospitalization for COVID-19: impact of hypertension and outcome prediction model

The aim – to study the influence of hypertension (HT) on the dynamics of natural recovery of physical functional status in the early period after hospitalization for COVID-19 and to develop a model for predicting recovery results at 1 month after discharge.Materials and methods. 221 hospitalized patients with COVID-19 (age 53.4±13.6 years, 53 % women) were included in the study, 176 of whom underwent the 6-minute walk test (6MWT) using an extended protocol within 1-2 days before discharge. A repeat visit to assess the dynamics of natural recovery was performed at 1 month after discharge.Results and discussion. Pre-discharge 6-minute walk distance was 378±57 m in patients with HT and 418±75 m without it, p=0.001, during the second visit – 440±52 versus 478±68, p=0.002; the achieved percentage of the individually predicted distance was 67.4±10.5 vs. 69.5±13.6 % and 81.6±9.9 vs. 81.9±15.7 %, respectively, p&gt;0.05 for both visits. The increase in heart rate during the test at visit 1 was 18.5±8.3 versus 30.1±19.3 bpm, p&lt;0.001, the percentage of chronotropic reserve utilizatoin was 21.3±9.6 % versus 29.2±11.4 %, p&lt;0.001. During the second visit, residual manifestations of this trend were observed, with an increase in HR by 24.0±9.5 vs. 30.8±12.1, p=0.003 and the use of chronotropic reserve of 28.1±10.1 % vs. 33.4±12.4 %, respectively, p=0.029. The developed multivariate linear regression model explained 59 % of the variability in the achieved percentage of the individually predicted 6-minute walk distance at 1 month after discharge. The use of machine learning allowed to create an artificial neural network based regression model that used age, height, use of remdesivir in treatment, and SBP and DBP values at the time of discharge as predictors, and explained 90 % of observed variability.Conclusions. Hospitalized patients with COVID-19 were characterized by a decrease in the general physical functional status as assessed by 6MWT at the time of discharge and incomplete recovery after 1 month. Presence of hypertension was associated with more pronounced disturbances of the autonomic regulation of heart rate, but did not affect the reached percentage of the distance walked. The proposed artificial neural network based regression model allows for a high accuracy prediction of the 6MWT results at 1 month after discharge, which can be used in the selection of candidates for cardiopulmonary rehabilitation programs.

Impairments of functional exercise capacity, muscle strength, balance and kinesiophobia in patients with chronic kidney disease: a cross-sectional study

BackgroundMuscle weakness, balance, and functional capacity are affected in patients with chronic kidney disease (CKD) in dialysis. However, studies about kinesiophobia, peripheral and respiratory muscle strength, balance, exercise capacity, fatigue, and physical activity level in patients with CKD 3–4 are limited. The study aimed to compare the functional exercise capacity, peripheral and respiratory muscle strength, pulmonary function, balance, kinesiophobia, physical activity, fatigue, and dyspnea between patients with CKD 3–4 and controls.MethodsThis cross-sectional study included 43 patients and 45 controls. Functional exercise capacity [6-Minute Walking Test (6MWT)], peripheral and respiratory muscle strength, pulmonary function, dyspnea, fatigue, physical activity, balance [Berg Balance Scale (BBS)], and kinesiophobia were evaluated.ResultsDemographic characteristics were similar in patients [53(50–57) y, 26 M/17F] and controls [51(4.506-55) y, 33 M/12F] (p > 0.05). The 6MWT, respiratory and peripheral muscle strength, pulmonary function, physical activity, and BBS were significantly lower, and the level of dyspnea and kinesiophobia were higher in patients compared with controls (p < 0.05).ConclusionsPatients had impaired functional exercise capacity, upper and lower extremity muscle strength, respiratory muscle strength, pulmonary function, and balance, increased perception of dyspnea and kinesiophobia, and reduced physical activity level compared with controls. Patients should be directed to cardiopulmonary rehabilitation programs.

Post-coronavirus disease-19: the impact of cardiopulmonary rehabilitation on arterial stiffness, left ventricular deformation, and ventricular-arterial coupling

Abstract Introduction Although coronavirus disease-19 (COVID-19) is a primarily a respiratory disease, impairment of cardiovascular function has been documented, even in the post-acute phase. Cardiopulmonary rehabilitation could represent an appealing approach in the management of cardiovascular sequelae of post-COVID-19, which may affect arterial and left ventricular function, ultimately influencing ventricular-arterial coupling (VAC). Purpose In this study, we assess the impact of a post-acute COVID-19 rehabilitation program on arterial stiffness, left ventricular deformation, and VAC. Methods We enrolled 60 convalescent patients from COVID-19 and one-month post-acute disease were randomized at 1:1 ratio in a 3-month cardiopulmonary rehabilitation program (study group) or not (control group). The levels of pro-inflammatory interleukin-1β (IL-1β) were determined. Arterial stiffness was evaluated by carotid-femoral Pulse wave velocity (cf-PWV) at 1 month and at 4 months post-acute disease. Transthoracic echocardiography was performed, and left ventricular global longitudinal strain (LV-GLS) was estimated. Finally, the ratio of cf-PWV/LV-GLS was calculated as an index of VAC. Results There were no significant differences in major risk factors across the studied groups (age, sex, body mass index, smoking, hypertension, diabetes mellitus, dyslipidemia). Moreover, patients across the study groups did not differ regarding the levels of IL-1β. Although cf-PWV was similar in the study and the control group at baseline, it was improved only in the study group (8.2±1.3m/sec vs. 6.6±1.0m/sec, p&amp;lt;0.001) but not in the control group (8.9±1.8m/sec vs. 8.8±1.9m/sec, p=0.74). Similarly, for GLS, no differences were noted at baseline. However, the study group exhibited a significant improvement during the study (-19.6±2.0% vs. -21.3±1.9%, p&amp;lt;0.001), while no changes were observed in the control group (-18.7±2.9% vs. -18.3±2.1%, p=0.15). Finally, VAC was significantly ameliorated only in patients receiving cardiopulmonary rehabilitation (-0.43±0.11m/s% vs. -0.31±0.06m/s%, p&amp;lt;0.001). When individuals undergoing cardiopulmonary rehabilitation were stratified according to median baseline IL-1β levels, those presenting with lower concentrations experienced a significant benefit in ΔVAC (IL-1β&amp;lt;8.4pg/ml: 0.14±0.08m/s% vs. IL-1β≥8.4pg/ml: 0.09±0.05m/s%, p=0.04). Conclusion A 3-month cardiopulmonary rehabilitation program following the acute phase of COVID-19 accelerates the recovering of arterial and ventricular function, especially in individuals with a lower baseline inflammatory burden.

Correlation between high sensitivity C reactive protein (Hs-CRP) and neutrophil-to- lymphocyte ratio (NLR) with functional capacity in post COVID-19 syndrome patients.

Post coronavirus disease 2019 (COVID-19) syndrome is one of the causes of reduced functional capacity and work productivity, in particular for healthcare workers. The pathophysiology of the post COVID-19 syndrome is related to complex and multisystem inflammatory mechanisms, and cardiopulmonary exercise rehabilitation program is one of the efforts to improve the recovery process for patients with post COVID-19 syndrome. The aim of this study was to determine the correlation between the level of high sensitivity C-reactive protein (Hs-CRP) and neutrophil-to-lymphocyte ratio (NLR) with functional capacity (VO2max) in individuals with post-COVID-19 syndrome who received moderate- and high-intensity supervised cardiopulmonary exercise. A prospective cohort study was conducted at the Integrated Cardiac Rehabilitation Center of Dr. Zainoel Abidin Hospital, Banda Aceh, Indonesia. The supervised cardiopulmonary exercise was conducted for six weeks according to the participant's baseline VO2max. Spearman's and Pearson's correlation tests were used to assess the correlations. A total of 30 individuals (19 and 11 had moderate and high intensity exercise, respectively) were involved in this study. At moderate intensity exercise, the average Hs-CRP and NLR were 3.3 mg/L and 1.99, respectively; while at high intensity, the values were 3.8 mg/L and 1.79, respectively. No significant correlation between Hs-CRP level and functional capacity in both moderate-intensity and high intensity groups. In contrast, NLR was negatively correlated with functional capacity (r=-0.545, p=0.016) in moderate intensity exercise group. In conclusion, NLR value was negatively correlated with functional capacity in individuals with post-COVID-19 syndrome after receiving moderate intensity supervised cardiopulmonary exercise program. Therefore, moderate intensity of cardiopulmonary exercise maybe be used as a program to accelerate the recovery for those with post COVID-19 syndrome.

Enhancing Quality of Life (QOL) And Cardiac Function in Heart Failure Patients Through Integrated Tele-Cardiopulmonary Rehabilitation And Psychological Support: A Prospective Study

Introduction: Herat failure (HF) is one global pandemic affecting millions of people across the globe. Patients with HF report decreased functional capacity, increased dyspnea and weariness, and a diminished ability to do daily tasks. In previous years there was much advancement in pharmacological therapy against heart failure. Several studies have shown that cardiopulmonary rehabilitation programs are safe and effective in improving functional capacity and quality of life while decreasing readmission rates and all-cause death in heart failure patients. However, heart failure patients' psychological status is often unknowingly neglected, leading to poor quality of life. Methods: This prospective Study was initiated in May 2022, was conducted for 18 months, and was completed in October 2022. This study is a prospective study of heart failure patients, the effect of an integrated approach of tele-cardiopulmonary rehabilitation along with psychologist-guided psychological support enhancing the quality of life. The patients satisfying the inclusion criteria without exclusion criteria were randomized to intervention and control groups. Results: The age group of the mean (years)+/- SD(67+/-14.4) in the Intervention Group and (66+/- 14) in the Control group. Both the groups comprised female participants, 63% in the Intervention group and 68% in the control group. The initial evaluation was done at the beginning of this prospective study. The follow-ups were done in 6 weeks, 12 weeks, and 24 weeks. Clinical examination, 6-Minute Walk Test, peak VO2 evaluation in a cardiopulmonary exercise test, and echocardiography with LVGLS measurements. During the study period, it was noted that there were substantial improvements in LVGLS, 6-Minute Walk Test distance, peak VO2, and Quality of Life. Conclusion: In Conclusion, based on the findings of this prospective study, the integrated approach of tele- cardiopulmonary rehabilitation and psychological support in heart failure patients has tremendous benefits and remarkable improvement in Quality of Life. As the life span improves, that leads to more heart failure patients presently and in the future. Along with pharmacotherapy against heart failure, telerehabilitation, and psychological support should be emphasized from the beginning of heart failure treatment to achieve a better quality of life. Considering the importance of Rehabilitation, through this study, it would not be wrong to suggest an additional pillar of heart failure treatment along with four other robust pillars in the guidelines

Adherence of females to Fitcor’s cardiopulmonary and metabolic rehabilitation program during 34 years

Introduction: In recent decades the number of deaths from heart disease among women in Brazil has increased a lot considerably, however those who accumulate more risk factors do not practice physical exercises. Objective: to investigate the adherence behavior of women aged between 12 and 80 years, to a specialized cardiac prevention and rehabilitation program (CPRP). Method: This cross-sectional descriptive study was carried out in a clinic specialized in cardiology diagnosis and CPRP between 1972 and 2006. Patients were separated into two groups, prevention (PG) and rehabilitation (RG) after physical evaluation and diagnosis. Both groups of women were separated by age and by the date of beginning CPRP. Results: Based on the entry diagnosis in the records of 958 women who attended the CPRP, we identified that 655 of them were in the prevention group (PG) and 303 in the rehabilitation group (PG). In both groups, the adherence to the program decreased with advancing age and worsening of risk factors. Conclusions: Contrary to the increase on statistics of women victims of cardiovascular diseases in Brazil, the number of those who seek CPRP through physical exercises has decreased and, what is worse, the number or places that facilitate women’s access to this type of intervention has also decreased.

Non-invasive ventilatory support accelerates the oxygen uptake and heart rate kinetics and improves muscle oxygenation dynamics in COPD-HF patients

BackgroundThe aim of this study was to explore the effects of non-invasive positive pressure ventilation (NIPPV) associated with high-intensity exercise on heart rate (HR) and oxygen uptake (V̇O2) recovery kinetics in in patients with coexistence of chronic obstructive pulmonary disease (COPD) and heart failure (HF). MethodsThis is a randomized, double blinded, sham-controlled study involving 14 HF-COPD patients, who underwent a lung function test and Doppler echocardiography. On two different days, patients performed incremental cardiopulmonary exercise testing (CPET) and two constant-work rate tests (80% of CPET peak) receiving Sham or NIPPV (bilevel mode - Astral 150) in a random order until the limit of tolerance (Tlim). During exercise, oxyhemoglobin and deoxyhemoglobin were assessed using near-infrared spectroscopy (Oxymon, Artinis Medical Systems, Einsteinweg, Netherland). ResultsThe kinetic variables of both V̇O2 and HR during the high-intensity constant workload protocol were significantly faster in the NIPPV protocol compared to Sham ventilation (P < 0.05). Also, there was a marked improvement in oxygenation and lower deoxygenation of both peripheral and respiratory musculature in TLim during NIPPV when contrasted with Sham ventilation. ConclusionsNIPPV applied during high-intensity dynamic exercise can effectively improve exercise tolerance, accelerate HR and V̇O2 kinetics, improve respiratory and peripheral muscle oxygenation in COPD-HF patients. These beneficial results from the effects of NIPPV may provide evidence and a basis for high-intensity physical training for these patients in cardiopulmonary rehabilitation programs.

The Role of Rehabilitation in Arterial Function Properties of Convalescent COVID-19 Patients.

Coronavirus disease (COVID-19) is a respiratory disease, although arterial function involvement has been documented. We assess the impact of a post-acute COVID-19 rehabilitation program on endothelium-dependent vasodilation and arterial wall properties. We enrolled 60 convalescent patients from COVID-19 and one-month post-acute disease, who were randomized at a 1:1 ratio in a 3-month cardiopulmonary rehabilitation program (study group) or not (control group). Endothelium-dependent vasodilation was evaluated by flow-mediated dilation (FMD), and arterial wall properties were evaluated by carotid-femoral pulse wave velocity (cf-PWV) and augmentation index (AIx) at 1 month and at 4 months post-acute disease. FMD was significantly improved in both the study (6.2 ± 1.8% vs. 8.6 ± 2.4%, p < 0.001) and control groups (5.9 ± 2.2% vs. 6.6 ± 1.8%, p = 0.009), but the improvement was significantly higher in the study group (rehabilitation) (p < 0.001). PWV was improved in the study group (8.2 ± 1.3 m/s vs. 6.6 ± 1.0 m/s, p < 0.001) but not in the control group (8.9 ± 1.8 m/s vs. 8.8 ± 1.9 m/s, p = 0.74). Similarly, AIx was improved in the study group (25.9 ± 9.8% vs. 21.1 ± 9.3%, p < 0.001) but not in the control group (27.6 ± 9.2% vs. 26.2 ± 9.8 m/s, p = 0.15). Convalescent COVID-19 subjects of the study group (rehabilitation) with increased serum levels of circulating IL-6 had a greater reduction in FMD. Conclusively, a 3-month cardiopulmonary post-acute COVID-19 rehabilitation program improves recovery of endothelium-dependent vasodilation and arteriosclerosis.

Functional capacity and cognitive performance of adults from Argentina in cardiopulmonary rehabilitation

Functional capacity is decreased in people with Cardiovascular Diseases and Chronic Respiratory Diseases. These diseases have also been associated with cognitive dysfunction. The study examines the efficacy of a cardiopulmonary rehabilitation program in the recovery of functional capacity and analyzes whether subjects with cardiopulmonary diseases suffer from cognitive dysfunction. Participated 50 adults with medium-high education who completed a cardiopulmonary rehabilitation program of between 3 and 6 months based on physical education, nutritional education, promotion of healthy habits and medication management. Functional capacity was evaluated with the Duke index at the beginning and end of the program. Memory and language tests were also administered, for the only time, at the beginning of the program, comparing the values obtained with Argentine normative studies. The data was analyzed with the Wilcoxon test, bivariate correlations, and linear regression. Functional capacity increased significantly at the end of the program. In any case, the post-program Duke value suggests that the functional capacity of the patients continues to be affected. On the other hand, a memory test explained 10,8% of the variance in the Duke index, and there are no findings of cognitive dysfunction. The functional capacity of cardiopulmonary patients improved with the rehabilitation program, although this improvement is clinically insufficient. Better memory performance predicted greater functional capacity, which is why it is suggested to add cognitive stimulation workshops to cardiopulmonary rehabilitation programs. This sample with cardiopulmonary disease does not present cognitive dysfunction, probably due to its high cognitive reserve.

Physicians' Perceptions of and Barriers to Cardiopulmonary Rehabilitation for Heart Failure Patients in Saudi Arabia: A Cross-Sectional Study.

Cardiopulmonary rehabilitation (CR) serves as a core component of the management strategy for patients with heart failure (HF). CR is administered by multidisciplinary healthcare providers, but their perceptions toward delivering CR to HF patients, and the factors and barriers that might influence referral, have not been studied. This study aims to assess physicians' perceptions toward delivering CR programs to HF patients and identify factors and barriers that might influence their referral decisions. Between 15 February and 5 June 2022, a cross-sectional online survey with ten multiple-choice items was distributed to all general and cardiac physicians in Saudi Arabia. The characteristics of the respondents were described using descriptive statistics. Percentages and frequencies were used to report categorical variables. The statistical significance of the difference between categorical variables was determined using the chi-square (2) test. Logistic regression was used to identify referral factors. Overall, 513 physicians (general physicians (78%) and cardiac doctors (22%)) completed the online survey, of which 65.0% (n = 332) were male. Of the general physicians, 236 (59%) had referred patients with HF to CR. Sixty-six (58%) of the cardiac doctors had referred patients with HF to CR. A hospital-supervised program was the preferred mode of delivering CR programs among 315 (79%) general physicians, while 84 (74%) cardiac doctors preferred to deliver CR programs at home. Apart from the exercise component, information about HF disease was perceived by 321 (80%) general physicians as the essential component of a CR program, while symptom management was perceived by 108 (95%) cardiac doctors as the essential component of a CR program. The most common patient-related factor that strongly influenced referral decisions was "fatigue related to disease" (63.40%). The availability of CR centers (48%) was the most common barrier preventing the referral of patients to CR. CR is an effective management strategy for HF patients, but the lack of CR centers is a major barrier to the referral of patients. A hospital-supervised program is the preferred method of delivering CR from the general physicians' perspective, while cardiac doctors prefer home-based CR programs. Apart from the exercise component, information about HF disease and symptom management is essential components of CR programs from general physicians' and cardiac doctors' perspectives, respectively.

The results of inspiratory muscle training on cardiac, respiratory, musculoskeletal, and psychological status in patients with stable angina: a randomized controlled trial

Purpose To determine the effect of inspiratory muscle training (IMT) on respiratory and peripheral muscle strength, functional exercise capacity, health-related quality of life (HRQoL), fatigue, depression, and cardiac functions in patients with stable angina. Methods A randomized, controlled, single-blinded study. Twenty patients (59.95 ± 7.35 y, LVEF = 58.77 ± 7.49) with stable angina received IMT at the lowest load (10 cmH2O), and 20 patients (55.85 ± 7.60 y, LVEF = 62.26 ± 7.75) received training at 30% of maximal inspiratory pressure (MIP) seven days/8 weeks. Respiratory muscle strength (MIP; maximal expiratory pressure, MEP), peripheral muscle strength, pulmonary functions, functional exercise capacity (6-min walking test; exercise test), fatigue, HRQoL, depression, and cardiac functions were evaluated before and after. Results A statistical difference was found between groups in terms of respiratory and peripheral muscle strength, pulmonary functions, functional exercise capacity (p < 0.05). The results of fatigue, depression, HRQoL, and cardiac functions were similar between the groups (p > 0.05). Conclusions This study is the first to demonstrate the positive effects of IMT in patients with stable angina. IMT is a safe and effective method and is recommended to be added to cardiopulmonary rehabilitation programs and guidelines, as it results in increased peripheral muscle strength and functional exercise capacity in stable angina patients. Implications for rehabilitation Inspiratory muscle training (IMT) is a safe and effective method for coronary artery disease (CAD) patients with stable angina. IMT improved respiratory and peripheral muscle strength, functional exercise capacity, pulmonary functions, and health-related quality of life in CAD patients with stable angina. Perception of depression and fatigue were decreased with IMT in CAD patients with stable angina.

Nurses’ Beliefs and Barriers of Delivering Cardiopulmonary Rehabilitation for Heart Failure Patients in Saudi Arabia: A Cross-Sectional Study

Background: Patients with heart failure (HF) may benefit greatly from cardiopulmonary rehabilitation (CR), which is provided by a team of healthcare professionals that often includes nurses. There has been no research on how nurses perceive providing CR or the hurdles that may affect referrals. Methods: All registered nurses in Saudi Arabia’s Eastern Province were given access to a cross-sectional online survey consisting of nine multiple-choice questions that address attitudes, beliefs, and barriers to CR for HF patients in Saudi Arabia. Descriptive statistics were used to characterize the respondents. Results: Altogether, 439 registered nurses participated in the online survey, with men making up 194 (44%) and women 245 (56%). The mean and SD of years of clinical experience in caring for patients with HF were 6 ± 5 years. Out of 439 nurses, 107 (24%) strongly agree, and 255 (58%) agree that CR will enhance the physical fitness of patients. However, 94 (21.1%) strongly agree, and 248 (56.4%) agree that CR might alleviate dyspnea in HF patients. The vast majority of the nurses either strongly agree (90 (20.5%)) or agree (240 (55%)), that CR would help reduce palpitations and fatigue in HF patients. Indeed, 87 (19.81%) strongly agree, and 262 (59.68%) agree that CR would help improve HF patients’ ability to perform daily activities, while 51 (11.6%) strongly agree and 223 (51%) agree that CR would help in reducing hospital readmission. It was shown that 360 (82%) of the 439 nurses favored the delivery of CR programs in hospital-supervised programs, while 368 (83.8%) ranked information on HF disease as the most important aspect of the CR program, followed by information about medications at 305 (69.4%). The availability of CR facilities (36%), the cost of therapy (35%), and the absence of an established standardized referring strategy (34%) were identified as the most significant barriers affecting the referral of patients with HF for CR by nurses. Conclusion: Generally, nurses believed CR helped improve desired clinical outcomes in HF patients. Although a hospital-based program with close supervision is optimal for administering CR, few such options exist. Referrals of patients with HF were hampered by the lack of CR facilities, the cost of intervention, and the lack of a systematic approach to referrals.
