Effect of home-based cardiac rehabilitation for patients with heart failure: a systematic review and meta-analysis / Rehabilitación para pacientes con insuficiencia cardíaca: una revisión sistemática y metanálisis

SUMMARY: This study is to investigate the effect of home-based cardiac rehabilitation (HBCR) on quality of life, functional capacity, and readmission rates in patients with heart failure. Randomized controlled trials (RCTs) were screened from Cochrane Library, CINAHL, EMBASE, and MEDLINE. The intervention group received a standardized HBCR or a comprehensive rehabilitation strategy that included HBCR. The participants in the control group received CR at a medical center or usual care without CR intervention. The main outcome measurements included quality of life, exercise capacity, mortality and re-hospitalization. This meta-analysis included 20 RCTs, in which 16 studies compared HBCR with usual care, and 4 studies compared HBCR with center-based CR. In comparison with the usual care, HBCR improved the total quality of life score [MD=-5.85, 95 % CI (-9.76, - 1.94), P=0.003, I2=75 %]. Patients with HBCR and usual care were significantly different in VO2max [MD=1.05 mL/kg/min, 95 % CI (0.35, 1.75), P=0.003, I2=46 %]. However, VO2max of patients with HBCR was not significantly different from those with center-based CR [MD=0.08 mL/kg/min, 95 % CI (-1.29, 1.44), P=0.91, I2=0 %]. There was statistically significant difference in the 6-min Walk Distance between usual care and HBCR (for distance [MD=11.84, 95 % CI (7.41, 16.28), P<0.00001, I2=0 %]; and for feet [MD=98.93, 95 % CI (26.79, 171.08), P=0.007, I2=56 %]). However, there was no significant difference in 6-min Walk Distance between patients with HBCR and center-based CR [MD=12.45, 95 % CI (-9.81, 34.72), P=0.27, I2=0 %] , or in anxiety and depression between patients with usual care and HBCR (for anxiety, [MD=-0.25, 95 % CI (-0.56, 0.05), P=0.11, I2=0 %]; for depression, [MD=-0.18, 95 % CI (-0.51, 0.16), P=0.30, I2=0 %] . No significant difference was found in death number [RR=1.04, 95 % CI (0.55, 1.98), P=0.90, I2=0 %] or in the number of re-hospitalization [RR=0.88, 95 % CI (0.66, 1.18), P=0.40, I2=0 %] between usual care and HBCR. For patients with heart failure, compare with usual care and center-based CR, HBCR can improve the total quality of life. Compare with usual care, HBCR can improve VO2max and 6-min Walk Distance, but compare with center- based CR, there are no differences in mortality, re-hospitalization rate or incidence of anxiety and depression. Additionally, center- based CR and HBCR showed similar outcomes and medical costs.

El objetivo de este estudio fue investigar el efecto de la rehabilitación cardíaca domiciliaria (HBCR) sobre la calidad de vida, la capacidad funcional y las tasas de reingreso en pacientes con insuficiencia cardíaca. Se seleccionaron ensayos controlados aleatorios (ECA) de la Biblioteca Cochrane, CINAHL, EMBASE y MEDLINE. El grupo de intervención recibió un HBCR estandarizado o una estrategia de rehabilitación integral que incluía HBCR. Los participantes del grupo de control recibieron RC en un centro médico o atención habitual sin intervención de RC. Las principales medidas de resultado incluyeron la calidad de vida, la capacidad de ejercicio, la mortalidad y la rehospitalización. Este metanálisis incluyó 20 ECA, en los que 16 estudios compararon HBCR con la atención habitual y 4 estudios compararon que mejoró la puntuación total de calidad de vida [DM=-5,85, IC del 95 % (-9,76, -1,94), P=0,003, I2=75 %]. Los pacientes con HBCR y atención habitual fueron significativamente diferentes en el VO2máx [DM = 1,05 ml/kg/ min, IC del 95 % (0,35, 1,75), P = 0,003, I2 = 46 %]. Sin embargo, el VO2max de los pacientes con HBCR no fue significativamente diferente de aquellos con CR basada en el centro [DM = 0,08 ml/kg/min, IC del 95 % (-1,29, 1,44), P = 0,91, I2 = 0 %]. Hubo una diferencia estadísticamente significativa en la distancia de caminata de 6 minutos entre la atención habitual y HBCR (para la distancia [DM=11,84, IC del 95 % (7,41, 16,28), P<0,00001, I2=0 %]; y para los pies [DM= 98,93, IC 95 % (26,79, 171,08), P=0,007, I2=56 %]). Sin embargo, no hubo una diferencia significativa en la distancia de caminata de 6 minutos entre los pacientes con HBCR y CR basada en el cen- tro [DM = 12,45, IC del 95 % (-9,81, 34,72), P = 0,27, I2 = 0 %], o en la ansiedad y depresión entre pacientes con atención habitual y HBCR (para ansiedad, [DM=-0,25, IC del 95 % (-0,56, 0,05), P=0,11, I2=0 %]; para depresión, [DM=-0,18, 95 % IC (- 0,51, 0,16), P=0,30, I2=0 %] No se encontraron diferencias significativas en el número de muertes [RR=1,04, IC del 95 % (0,55, 1,98), P=0,90, I2=0 %] o en el número de reingresos [RR=0,88, IC 95 % (0,66, 1,18), P=0,40, I2=0 %] entre atención habitual y HBCR. Para los pacientes con insuficiencia cardíaca, en comparación con la atención habitual y la CR en un centro, la HBCR puede mejorar la calidad de vida total. En comparación con la atención habitual, la HBCR puede mejorar el VO2máx y la distancia recorrida en 6 minutos, pero en comparación con la CR basada en un centro, no hay diferencias en la mortalidad, la tasa de rehospitalización o la incidencia de ansiedad y depresión. Además, CR y HBCR basados en el centro mostraron resultados y costos médicos similares.

Effects of physical training of patients with atrial fibrillation in cardiovascular rehabilitation regimen Introduction: There are still few studies that recommend patients with atrial fibrillation in cardiovascular rehabilitation programs. Objective: To evaluate the effects of physical training in patients with atrial fibrillation undergoing cardiovascular rehabilitation. Method: A pre-experimental, prospective, pretest-posttest study was carried out with 18 patients with atrial fibrillation who attended cardiac rehabilitation sessions for 12 weeks. The patient was evaluated at the beginning and end of the program with stress test with expired gases, blood test and transthoracic echocardiogram. Results: The male sex (72.2%), the diagnosis of cardiomyopathies (33.3%), arterial hypertension (100%) and longterm persistent atrial fibrillation (55.6%) predominated. A statistically significant difference was found for each morphofunctional variable: body mass index (28.0±5.0 vs. 26.9±4.4, p<0.0001), peak oxygen consumption (13.6±3.0 vs. 15.3±2.9, p<0.0001), oxygen at the anaerobic threshold (9.9±2.2 vs. 10.7±2.0; p=0.007), ventilatory equivalent for carbon dioxide (27.7±4.7 vs. 26.6±4.7; p<0.0001), ventilatory equivalent for oxygen (24.2± 5.0 vs. 23.8±4.9 p=0.001), oxygen pulse (10.2±2.5 vs. 12.1±2.1; p<0.0001), metabolic units (3.8±0.9 vs. 4.3±0.9; p<0.0001) and fraction of left ventricular ejection (55.7±8.7 vs. 58.2±7.5, p=0.003). The metabolic variables decreased significantly (p<0.0001). Weber's functional class improved in 5 patients (27.8%). Conclusions: Physical training of patients with atrial fibrillation during 12 weeks of cardiovascular rehabilitation improved functional capacity, with progressive increases in left ventricular ejection fraction and decrease in metabolic variables, without generating risks or complications.

Exercise Training Improved Pulmonary Gas Exchange Abnormalities in Pulmonary Hypertension due to Heart Failure: A Case Report

Abstract Heart failure (HF) is the most common cause of pulmonary hypertension (PH), and reduced exercise capacity and exertional dyspnea are the most frequent concerns in patients with PH-HF. Indeed, carbon dioxide end-tidal partial pressure (PETCO 2 ) during exercise is a well-established noninvasive marker of ventilation/perfusion ratio in PH. We aimed to evaluate the effect of aerobic exercise training on PETCO 2 response during exercise in a 59-year-old woman with PH secondary to idiopathic dilated cardiomyopathy. The patient with chronic fatigue and dyspnea at mild-to-moderate efforts was admitted to a cardiorespiratory rehabilitation program and had her cardiorespiratory response to exercise assessed during a cardiopulmonary exercise testing performed before and after three months of a thrice-weekly aerobic exercise training program. Improvements in aerobic capacity (23.9%) and endurance time (37.5%) and reduction in ventilatory inefficiency (-20.2%) was found after intervention. Post-intervention improvements in PETCO 2 at ventilatory anaerobic threshold (23.3%) and change in PETCO 2 kinetics pattern, with progressive increases from rest to peak of exercise, were also found. Patient also improved breathing pattern and timing of ventilation. This case report demonstrated for the first time that aerobic exercise training might be able to improve PETCO 2 response during exercise in a patient with PH-HF.

Continuous Aerobic Training and High Intensity Interval Training Increase Exercise Tolerance in Heart Failure Patients: A Retrospective Study

Abstract Background: Conventional aerobic training is the first choice in cardiac rehabilitation for patients with chronic heart failure (CHF). However, high-intensity interval training (HIIT) may be an alternative, although it has little evidence. Objectives: To evaluate the effect of continuous aerobic training (CAT) or HIIT on exercise tolerance in CHF patients. Methods: Retrospective study with 30 patients, of both genders, members of a 10-week CAT or HIIT program. The control group (CON) consisted of patients who did not participate voluntarily in the program. Peak oxygen uptake (VO2peak), thresholds (LV1 and LV2), and ventilatory efficiency in the production of dioxide (VE/VCO2 slope), oxygen uptake efficiency (OUES), and VO2 recovery kinetics were analyzed. A two-way or repeated measures ANOVA was used, followed by Fisher's post-hoc test (p<0.05). Results: After 10 weeks of training, the CAT group increased the treadmill speed at LV1 (p=0.040), while the HIIT increased both the speed (p=0.030) and incline of the treadmill (p<0.001) for VO2peak and LV2, as well as the total time of the cardiopulmonary test. The VE/VCO2 slope was lower than that predicted for CAT (p=0.003) and HIIT (p=0.008). There was no change in VO2peak, recovery of heart rate (HR), and VO2, VE/VCO2, and OUES in both groups. Conclusions: After 10 weeks, both CAT and HIIT increased the tolerance to physical exercise. However, HIIT showed improvement in more parameters, differently from CAT.

Prescripción de ejercicio durante la rehabilitación cardiaca de pacientes con Insuficiencia Cardiaca / Exercise prescription in patients with heart failure during cardiac rehabilitation

Resumen La insuficiencia cardiaca (IC) es una patología cardiovascular con elevada morbi-mortalidad, sus causas más frecuentes se asocian a la cardiopatía isquémica y la hipertensión arterial. La rehabilitación cardiaca (RC) ha demostrado ser efectiva para mejorar la sintomatología, la capacidad funcional, el número de internamientos y la mortalidad en personas con dicha enfermedad. A pesar de esto, se ha documentado que la RC y el ejercicio físico como uno de sus componentes, siguen siendo subutilizados. Se revisa la evidencia científica y guías de práctica clínica disponibles, con el objetivo de valorar la seguridad, la respuesta y los beneficios del ejercicio en personas con IC, incluyendo las recomendaciones sobre prescripción, modalidades de entrenamiento (HIIT, músculos respiratorios y electroestimulación muscular funcional) y finalmente las consideraciones especiales durante el proceso de RC.

Abstract Exercise prescription in patients with heart failure during cardiac rehabilitation. Heart Failure (HF) is a cardiovascular disease with high morbidity and mortality. The most frequent causes are associated with ischemic heart disease and high blood pressure. Cardiac rehabilitation (CR) has been shown to be an effective method in improving symptoms, functional capacity, also in reduce of the number of hospitalizations and mortality in people with this disease. Despite this, it has been documented that CR and physical exercise continue to be underused. The scientific evidence and available clinical practice guidelines are reviewed, in order to assess the safety, response, and benefits of exercise in people with HF, including recommendations on prescription, training modalities (HIIT, respiratory muscles, and functional muscle electrostimulation) and finally the special considerations during the CR process.

Objective: To evaluate he functional capacity of patients with ischemic cardiopathy who have been rehabilitated with physical therapy, according to the ergometric trace. Method: A descriptive, longitudinal and prospective study was carried out in the Physical Therapy and Rehabilitation Service from Dr. Juan Bruno Zayas Teaching in Santiago de Cuba during the biennium 2007-2019, in 41 patients who had suffered from a myocardial infarction and were included in a cardiovascular rehabilitation program. To determine the functional capacity, the cardiovascular risk level was compared to the functional class before and after the physical exercise. Results: It was achieved to modify the ergometric response in 87.8 % after applying the rehabilitation program, while the cardiovascular state according to the risk level of the patients was modified in 68.2 % towards the low risk and the functional capacity showed an improvement of 82.9 %. Conclusions: The implementation of a cardiac rehabilitation program was useful in most of the patients, and a significant improvement of the evaluated cardiovascular parameters was obtained, what pointed at a reestablishment of the life quality and of tolerance to efforts.

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.

Resultados: Se analizaron un total de 1516 estudios de los cuales se incluyeron 21 artículos. La muestra fue de 1316 pacientes con ECV. Existe una prevalencia de eventos adversos de 3.8% en la RCD y de 4.3% en RCT. El VO2máx aumentó entre 4.1% a 39.6% utilizando la RCD y entre 4% y 54.1% con RCT. La capacidad funcional incrementó entre 3.0% y 11.7% con RCD y entre 4.9% y 11.8% con RCT. Conclusiones: Los programas de RCD son tan seguros y eficaces como los programas de RCT manifestando incrementos similares en el VO2máx y la capacidad funcional.

Abstract Home cardiac rehabilitation as an alternative in times of pandemic: a systematic review The worldwide pandemic caused by the coronavirus disease (COVID-19) has produced global health, economic and social impact, as well in traditional cardiac rehabilitation (CR) programs. Patients with cardiovascular disease (CVD) should be encouraged to keep doing exercise, despite the pandemic. Objective: To analyze the scientific evidence on home-based CR (HBCR) and traditional CR (TRC) in patient safety and its efficacy in improving the maximum oxygen volume (VO2max) and functional capacity in patients with CVD. Methods: This systematic review was developed through PRISMA agreements. The scientific articles were searched using the electronic databases: "PubMed", "ScienceDirect", "Academic Search Ultimate" and "SportDiscus". Two search terms or Boolean phrase were used: ("heart disease" OR "cardiac diseases" OR "coronary artery disease" OR "heart failure") AND ("cardiac rehabilitation" OR "center-based" OR "exercise" OR "training") AND ("home-based" OR "home training" OR "home exercise") NOT ("animal"). Results: A total of 1516 studies were reviewed where 21 articles were included and 1316 patients with CVD that met inclusion criteria. The prevalence of adverse events was 3.8% in HCR and 4.3% in TCR. VO2max increased from 4.1% to 39.6% with HCR and between 4.0% to 54.1% with TCR. Functional capacity increased between 3.0% to 11.7% with HCR and between 4.9% and 11.8% withTCR. Conclusions: This scientific evidence shows that HBCR programs are as safe and effective as TCR programs providing similar improving effects on increasing VO2max and functional capacity and offering a great exercise alternative during the COVID-19 pandemic.

Capacidade funcional em populações especiais antes e após cinesioterapia passiva e alongamento / Functional capacity in special populations before and after passive kinesiotherapy and stretching / Capacidad funcional en poblaciones especiales antes y después de la kinesioterapia pasiva y el estiramiento

Objetiva-se analisar a capacidade funcional antes e depois de um tratamento com cinesioterapia passiva e alongamento em populações especiais. Estudo de caso, exploratório, retrospectivo, com uma abordagem quantitativa dos dados. A amostra da pesquisa foi constituída por homens na faixa etária entre 60 a 76 anos de idade, sedentários, com coronariopatias e co-morbidades associadas. Foram analisadas as fichas de avaliação e da reavaliação realizadas com o Senior Fitness Test entre julho a agosto de 2017. A estatística foi realizada através do software SISVAR. As co-morbidades associadas mais frequentes foram: dislipidemia e Hipertensão Arterial Sistêmica. No teste T1, houve um aumento no número de repetições nos movimentos de sentar e levantar da cadeira nos participantes 3, 7 e 10. No T2, ocorreu uma melhora no movimento de flexão do antebraço nos participantes 7 e 8. No T3, os participantes 3, 9, e 10 apresentaram uma melhora na flexibilidade dos MMII. O T4 verificou que os participantes 3 e 7 foram melhores na velocidade, agilidade e equilíbrio dinâmico. O T5 confirmou que apenas o participante 8 apresentou resultados significativos quanto à flexibilidade dos MMSS. No T6 e T7, não houve diferença significativa entre paciente x tempo quanto à resistência aeróbica e IMC respectivamente após o tratamento. Os resultados do Senior Fitness Test em populações especiais parece ser uma ferramenta capaz de analisar individualmente as necessidades de cada participante de um protocolo com reabilitação cardíaca de forma segura e prática; no entanto, se faz necessária uma amostra mais significativa.

Objective: To analyze the functional capacity before and after a treatment with passive kinesiotherapy and stretching in special populations. Method: Exploratory, retrospective case study with a quantitative data approach.The research sample consisted of men in the age group between 60 and 76 years of age, sedentary, with coronary diseases and associated comorbidities. We analyzed the evaluation and revaluation sheets made with Senior Fitness Test between July and August 2017. The statistics were performed using the SISVAR software. Results: The most frequent associated comorbidities were: dyslipidemia and Systemic Arterial Hypertension. In the T1 test, there was an increase in the number of repetitions in the sit and stand movements in the participants 3, 7 and 10. In T2 there was an improvement in the movement of forearm flexion in participants 7 and 8. In T3 participants 3, 9, and 10 presented an improvement in the flexibility of LLLs. T4 found that participants 3 and 7 were better at speed, agility, and dynamic balance. The T5 confirmed that only the participant 8 presented significant results regarding the flexibility of the MMSS. At T6 and T7, there was no significant difference between patient and time for aerobic endurance and BMI respectively after treatment. Conclusion: The results of Senior Fitness Test in special populations seem to be a tool capable of analyzing individually the needs of each participant of a protocol with cardiac rehabilitation in a safe and practical way, however a more significant sample is necessary.

Reabilitação cardiovascular com ênfase no exercício físico para pacientes com doença arterial coronariana: visão crítica do cenário atual / Cardiovascular rehabilitation with an emphasis on physical exercise for patients with coronary artery disease: a critical review of the current scenario

A doença arterial coronariana (DAC) é umas das doenças cardiovasculares que mais mata no Brasil e no mundo. É uma doença multifatorial, associada a fatores de risco modificáveis. Além dos tratamentos convencionais, é recomendado que pacientes com DAC também incluam modificações no estilo de vida e programas de reabilitação cardiovascular com ênfase no exercício físico (RCEE) em seu tratamento. Sabidamente, o exercício físico regular somado às mudanças no estilo de vida contribui para a diminuição do avanço da doença aterosclerótica e da mortalidade dos pacientes com DAC. Além disso, o exercício físico tem impacto benéfico na capacidade funcional e qualidade de vida. Um programa de RCEE é uma estratégia eficaz, segura e com excelente razão de custo-benefício para o tratamento da DAC. Contudo, mesmo sendo uma terapia recomendada pelos principais órgãos de saúde, no Brasil as políticas públicas de saúde são extremamente escassas e a quantidade de centros especializados que oferecem a RCEE também é baixa. Problemas de adesão, participação e motivação são evidentes quando os programas são avaliados. Esta revisão mostra os principais estudos que, ao longo das últimas décadas, deram base para as recomendações da RCEE e faz uma análise crítica do cenário atual, deixando claro que novas estratégias de atuação e monitoramento devem ser exploradas e incentivadas para que os programas de RCEE sejam incluídos efetivamente no tratamento dos pacientes com DAC

Coronary artery disease (CAD) is one of the most lethal cardiovascular diseases both in Brazil and worldwide. It is a multifactorial disease associated with modifiable risk factors. In addition to conventional treatments, it is recommended that patients with CAD also include lifestyle changes and exercise-based cardiovascular rehabilitation (CR) programs in their treatment. It is well known that regular physical exercise combined with lifestyle changes contributes to a reduction in the progression of atherosclerosis and in mortality in patients with CAD. Moreover, physical exercise has a beneficial impact on functional capacity and quality of life. A CR program is an effective, safe strategy for the treatment of CAD with an excellent cost-benefit ratio. However, even though it is a therapy recommended by the main health agencies, public health policies in Brazil are extremely scarce and the number of specialized centers that offer CR is low. Problems of adherence, participation, and motivation are evident when these programs are evaluated. This review looks at the main studies that have been the basis for the recommendations of CR over last decades and critically analyzes the current scenario, making it clear that new strategies for action and monitoring should be explored and encouraged such that CR programs will be included effectively in the treatment of patients with CAD

Acute response to aerobic exercise on autonomic cardiac control of patients in phase iii of a cardiovascular rehabilitation program following coronary artery bypass grafting

Abstract Objective: The aim of the present study was to investigate the acute response to aerobic exercise on autonomic cardiac control of patients undergoing coronary artery bypass grafting (CABG). Methods: The study sample consisted of eight patients (age: 58.6±7.7 years; body mass index: 26.7±3.5 kg.m2) who underwent a successful CABG (no complications during surgery and/or in the following weeks). To assess heart rate variability (HRV), participants remained in a supine position with a 30-degree head elevation for 20 minutes. Electrocardiographic signal (protocol with three derivations) was collected from 600 Hz sample rate to obtain beat-to-beat intervals (R-R interval). This assessment was performed before, after one hour and after 24 hours of the exercise session. All patients underwent a 35 minutes aerobic exercise session (AES) (low-moderate intensity) on the cycle ergometer. Results: Significant differences were found in the time domain, with positive changes in root mean square of successive RR interval differences (rMSSD) (ms) (parasympathetic component) (one [P=0.017] and 24 hours [P=0.007] post-session). In the frequency domain, we found a significant difference in high frequency (HF) (ms2) (parasympathetic component) (one hour [P=0.048] post-session). The low frequency (LF)/HF ratio (sympathetic and parasympathetic components with a predominance of the sympathetic component) reached statistical significance only 24 hours (P=0.018) post-session. Additionally, the largest effect size was observed only for the LF/HF ratio at one (d=-0.8) and 24 hours (d=-1.3) after one AES. Conclusion: The practice of (acute) aerobic exercise improved autonomic cardiac control in patients undergoing CABG.

Rehabilitación cardíaca fase I: progresión según pasos protocolizados en pacientes cardioquirúrgicos en un hospital público de Chile / Phase I cardiac rehabilitation: progression through protocolized steps in cardiosurgical in-patients in a public hospital in Chile

Resumen: Antecedentes: La Rehabilitación Cardíaca disminuye las complicaciones de la cirugía cardíaca y es mundialmente reconocida. A pesar de esto, en Chile su desarrollo ha sido lento y el reporte de experiencias bajo. Objetivo: Describir la progresión de acuerdo los pasos de rehabilitación y días postoperatorios en pacientes de rehabilitación cardíaca fase I en un hospital público de Temuco, Chile. Metodología: Se analizó una serie de casos de pacientes en rehabilitación cardíaca fase I, participantes de un protocolo basado en hitos motores de seis pasos: movilización en cama (P1); sedente borde cama (P2); marcha de 35 mts (P3); marcha hasta 100 mts (P4); marcha hasta 200 metros más subir/bajar un piso de escaleras (P5); marcha de 300 metros más subir/bajar dos pisos de escaleras (P6). Resultados: Se incluyeron 243 pacientes (1.033 sesiones) con una media de 65.9 años (DS 9.5), mediana de hospitalización 6 días. Del total de atenciones realizadas el día 1, en 53% de ellas se alcanzó el P1; en el día 2, en un 51% se alcanzó el P2 y en un 42% un paso ≥P3; en el día 3, en 44.78% se alcanzó paso ≥P4; en el día 4, en 37.75% se alcanzó ≥P4. En los días 5-7, aproximadamente 50% logró ≥P5. Conclusión: La progresión de los pasos es proporcional al día postcirugía y es más rápida en hombres. Al momento del alta, 75% de los pacientes alcanza una independencia funcional que les permite caminar dos cuadras y subir/bajar un piso de escaleras.

Abstract Background: Despite advances in cardiovascular disease management and the development of minimally invasive approaches, open cardiac surgery is still a preferred intervention in complicated cases. Phase I Cardiac Rehabilitation decreases complications associated with this intervention. Globally, cardiac rehabilitation is widely recommended. However, in Chile the implementation of this intervention has been slow and there are scarce reports of its result. Objective: To describe the progression according to steps and post-surgery days in cardiac rehabilitation phase I patients in the public hospital in Temuco, Chile. Methodology: We analyzed a series of cases of patients in cardiac rehabilitation phase I, participants of a protocol based on six-step motor levels: (S1) on-bed mobilization, (S2) sitting on the edge of the bed, (S3) Bipedal exercise and 35 meter walking, (S4) 100 meter walking, (P5) 200 meter walking plus going up one floor and down stairs, and (S6) 300 meter walking plus going two floors up and down stairs. Results: 243 patients were included, and 1,033 sessions were performed) Mean age was 65.9years-old (SD 9.5) and hospital stay run for a median of 6 days. From all sessions, on day one, 53% of patients reached S1. On day 2, 51% reached S2 and 36% walked (S3). On day 3, 44.78% reached ≥S4. On day 4, 37.75% reached ≥S4. On days 5-7, approximately 50% achieved ≥S5. Conclusion: the step progression is proportional to number of days after surgery, faster in men than compared to women. At discharge, 75 % of patients show functional independency that allows them to walk two blocks and go one floor up and down stairs.
