Efectos de un programa de rehabilitación cardíaca fase iii en la capacidad funcional y composición corporal en pacientes con cardiopatía isquémica / Effects of a Phase III cardiac rehabilitation program on functional capacity and body composition for coronary heart disease

Introducción y objetivos: Los programas de rehabilitación cardíaca (PRC) fase III han sido poco investigados tanto por los métodos de entrenamiento como por las modalidades de administración. Estudiamos los efectos en capacidad funcional, composición corporal y adherencia a la actividad física de un PRC interdisciplinar basado en ejercicio terapéutico aeróbico combinado con fuerza muscular tras síndrome coronario agudo. Diseño del estudio: Ensayo clínico aleatorizado. Métodos: Ochenta pacientes con cardiopatía isquémica estable y función sistólica preservada fueron incluidos posteriormente a un PRC fase II. Se distribuyeron en grupo control (GC), con ejercicio autónomo y grupo experimental (GE), con ejercicio aeróbico combinado con fuerza muscular comunitaria, además de estrategia educativa de mensajería telefónica instantánea. Ambos grupos realizaron terapia grupal hospitalaria. Se compararon los resultados de capacidad funcional, composición corporal y nivel de actividad física tras 12 meses. Resultados: La capacidad funcional presentó niveles más altos en el GE en la prueba de marcha de 6min, 26,03m (DE: 27,4; p<0,001), y en la ergometría incremental convencional, 0,6METs (DE: 2,2; p=0,021). El nivel de actividad física domiciliaria medido con el cuestionario IPAQ en el GE incrementó 90,38min/semana (DE: 79,7; (p=0,047), y disminuyó el tiempo sedentario entresemana −50,3min/día (DE: 94,5; p=0,001). Ambos grupos aumentaron el tejido adiposo, sobre todo el GC 1,4% (DE: 3,1; p=0,039). Conclusiones: Los pacientes con síndrome coronario agudo que realizaron un PRC fase III comunitario durante 12 meses, mediante ejercicio terapéutico aeróbico combinado con fuerza muscular y estrategias educativas de mensajería telefónica instantánea, presentaron niveles más altos en capacidad funcional y actividad física reportada.(AU)

Introduction and objectives: The effects of a phase III cardiac rehabilitation program (CRP) have been insufficiently studied in terms of training methods and administration. We studied the impact on functional capacity, body composition and physical activity engagement of interdisciplinary program based on aerobic and community strength therapeutic exercise after an acute coronary syndrome. Trial design: Randomised clinical trial. Methods: Eighty consecutive patients with stable ischemic heart disease and preserved systolic function before phase II CRP were included. They were distributed into a control group (CG), with autonomous exercise, and an experimental group (EG), that follows supervised community program based on aerobic exercise and overload dynamic muscle strength, and an educational strategy through short messaging. Both groups underwent monthly inpatient group therapy. Results were compared after 12 months. Results: Functional capacity presented higher levels in the EG and measured by the 6-min walk test (26.0±27.4m; P<.001), and maximal exercise test (0.6±2.2METs; P=.021). Home physical activity measured in minutes by IPAQ questionnaire increased more in the EG (90±78min/week) (P=.047), and the sitting time during the week decreased (−50.25±94.48min/day) (P=.001). There were no differences in body mass index, although we found a higher percentage of adipose tissue in CG after 12 months (P=.039). Conclusions: A multidisciplinary community phase III CRP based on aerobic and dynamic muscle strength therapeutic exercise combined with a short message service educational strategy was feasible. After 12 months, patients in the EG presented higher levels on functional capacity, reported higher physical activity engagement compared to the CG.(AU)

Efectos de un programa interdisciplinar combinado con entrenamiento aeróbico continuo variable y fuerza dinámica en el síndrome coronario agudo / Effects of an interdisciplinary program combining aerobic interval training and dynamic strength in acute coronary syndrome

Antecedentes y objetivo: La rehabilitación cardíaca tiene el máximo nivel de evidencia en las guías médicas de referencia, sin embargo, existen todavía modalidades de entrenamiento poco exploradas. Estudiamos los efectos de un programa interdisciplinar tras síndrome coronario agudo (SCA) en prevención secundaria fase II. Métodos: Entre enero 2008 y diciembre 2018 se incluyeron 439 pacientes con cardiopatía isquémica estable y función sistólica preservada, máximo dos meses después del SCA. Se aplicó un entrenamiento combinado de resistencia aeróbica en método continuo variable de alta intensidad y de tonificación muscular dinámica con sobrecarga y/o lastre, además de asesoramiento nutricional y terapia psicológica-educativa durante 12 semanas. Resultados: Finalizaron 378 pacientes. La capacidad funcional aumentó en la prueba de esfuerzo incremental (1,76 METS; IC 95% 1,59 a 1,96 p < 0,001) y en la prueba de marcha de seis minutos (32,58 m; IC 95% 29,24 a 35,92 p < 0,001). Aumentó la actividad física de ocio en el IPAQ (763,27 min/semana; IC 95% 583,31 a 943,16 p < 0,001) y disminuyó el tiempo sentado entre semana (-28,85 min/día; IC 95% -43,94 a -13,77 p < 0,001). Además, mejoraron los hábitos alimentarios en el PREDIMED (2,58 unidades; IC 95% 1,43 a 3,73 p < 0,001), disminuyó el peso corporal (-0,88 kg; IC 95% -1,26 a -0,49 p < 0,001), el perímetro abdominal (1,57 cm; IC 95% 2,23 a 0,90 p < 0,001) y el tejido adiposo (-0,80%; IC 95% -1,10 a -0,51 p < 0,001). Conclusiones: Un programa interdisciplinar con entrenamiento continuo variable de alta intensidad combinado con tonificación muscular dinámica produce mejorías en la capacidad funcional, en el nivel de actividad física, en la composición corporal y en los hábitos alimentarios en pacientes con SCA.(AU)

Introduction and objectives: Cardiac rehabilitation has the highest level of recognition in medical guideline references, however there are still little-explored training modalities. We study the effects of an interdisciplinary program after acute coronary syndrome (ACS) in phase II secondary prevention. Methods: Between January 2008 and December 2018, 439 patients with stable ischemic heart disease and preserved systolic function were included, as maximum 2 month after the ACS. A combined aerobic resistance training program in a variable continuous method and muscle toning with overload and/or ballast was applied, in addition to nutritional counseling and psychological-educational therapy for 12 weeks. Results: 378 patients finished. The functional capacity increases in the incremental stress test (1.76 METS; CI 95%: 1.59–1.96, p < 0.001) and in the six minutes walking test (32.58 m; CI 95%: 29.24–35.92, p < 0.001). Leisure physical activity in IPAQ increased (763.27 min/week; CI 95%: 583.31–943.16, p < 0.001) and the time sitting during the week decreased (−28.85 min/day; CI 95%: −43.94 to −13.77, p < 0.001). Also, eating habits improved in PREDIMED (2.58 units; CI 95%: 1.43–3.73, p < 0.001), decreased body weight (−0.88 kg; CI 95%: −1.26 to −0.49, p < 0.001), the abdominal perimeter (1.57 cm; CI 95%: 2.23–0.90, p < 0.001) and adipose tissue (−0.80%; CI 95%: −1.10 to −0.51, p < 0.001). Conclusions: An interdisciplinary program with high intensity variable continuous training combined with dynamic muscle toning increases functional capacity, the level of physical activity, improves body composition and eating habits in ACS patients.(AU)

Efectos del entrenamiento de fuerza domiciliario durante el confinamiento por COVID-19 en el síndrome coronario agudo / Effects of home-based strength training during COVID-19 lockdown in acute coronary syndrome

Introducción y objetivo: La rehabilitación cardíaca tiene el máximo nivel de evidencia en las guías médicas de referencia. Estudiamos los efectos de un programa interdisciplinar dirigido mediante telemedicina tras síndrome coronario agudo en prevención secundaria fase ii en periodo de confinamiento por COVID-19. Métodos: Entre el 2 y 11 de marzo de 2020 se incluyeron 37 pacientes predominantemente con cardiopatía isquémica estable (76,4%) y función sistólica preservada sometidos a tratamiento 12 semanas. Se aplicó un programa de entrenamiento de tonificación muscular dinámico con sobrecarga domiciliario, además de asesoramiento nutricional y terapia psicológica y educativa mediante telemedicina. Resultados: De la cohorte inicial, finalizaron 30 pacientes. La capacidad funcional aumentó en la prueba de marcha de seis minutos (47,13m; IC95% 32,82 a 61,45; p<0,001), donde se produjo también un descenso de la sensación subjetiva de disnea inicial (−0,5unidades; IC95% −0,76 a −0,24; p=0,001) en la escala de Borg modificada y de la tensión arterial sistólica inicial (−6,67mmHg; IC95% −10,98 a −2,35; p=0,004) y final (−7mmHg; IC95% −12,86 a −1,14; p=0,021). Se observó un aumento del nivel de actividad física en el tiempo de ocio en el IPAQ (1162,93min/semana; IC95% 237,36 a 2088,5; p=0,016) y mejoraron los hábitos alimentarios mediterráneos en el test PREDIMED (2,1unidades; IC95% 1,32 a 2,28; p<0,001). Conclusiones: Los pacientes que realizaron 3 meses de rehabilitación cardíaca domiciliaria aumentaron la capacidad funcional y mejoraron los hábitos higiénico-alimentarios, además disminuyeron su sensación de disnea inicial. La rehabilitación cardíaca domiciliaria mediante telemedicina produce una mejoría del paciente tras sufrir síndrome coronario agudo.(AU)

Introduction and objective: Cardiac rehabilitation has the highest level of recognition in medical guideline references. The rise of COVID-19 pandemic, particularly during the first months of strict containment, cause to temporally stop most of the ongoing programs. We studied the effects of an interdisciplinary phase II secondary prevention in patients diagnosed with a recent acute coronary syndrome with the use of new technologies, home-exercise and telemedicine. Methods: Between the 2nd and 11th of March 2020, we included 37 patients with recent acute coronary syndrome (76.4%), low-risk and preserved systolic function and underwent a 12-week treatment. A dynamic muscle toning with overload domiciliary training program was applied, in addition to nutritional counselling, as well as psychological and educational therapy. Results: Of the initial cohort, 30 patients finished. At the end of the program, we observed and increased functional capacity over the 6-min walking test (+47.13m; 95% CI: 32.82-61.45, P<.001), and improvement to the subjective feeling of dyspnoea on the modified Borg scale (−0.5 units; 95% CI: −0.76 to −0.24, P=.001), and an improvement over both initial and final training systolic blood pressure (−6.67mmHg; 95% CI: −10.98 to −2.35, P=.004) (−7mmHg; 95% CI: −12.86 to −1.14, P=.021). We also observed an increase in the level of physical activity during leisure time in the IPAQ questionnaire (+1162.93min/week; 95% CI: 237.36–2088.5, P=.016), and in the Mediterranean eating habits on the PREDIMED test (+2.1units; 95% CI: 1.32–2.28, P<.001). Conclusions: After three months of a domiciliary cardiac rehabilitation program, patients increased their functional capacity, feeling of dyspnoea, blood pressure and eating habits. Domiciliary telemedicine cardiac rehabilitation program produces an improvement in the patient after acute coronary syndrome.(AU)

Análisis comparativo de los valores de las presiones respiratorias máximas con los valores de referencia en una población adulta sana / Comparative analysis of maximal respiratory pressures with the reference values of a healthy adult population

Antecedentes y objetivo: La determinación de las presiones respiratorias máximas es un procedimiento no invasivo de gran utilidad clínica para la evaluación de la fuerza de los músculos respiratorios. El objetivo es analizar en qué medida las ecuaciones predictivas existentes para población española, se ajustan a los valores observados de presión inspiratoria y espiratoria máximas (PEM y PIM) en una muestra de sujetos adultos sanos. Material y métodos: Estudio descriptivo observacional de corte transversal en el que se reclutaron 63 sujetos sanos mediante muestreo probabilístico aleatorizado simple entre la comunidad universitaria de la Universidade da Coruña. Las presiones respiratorias máximas se efectuaron con un transductor de presiones conectado a una boquilla de submarinista, siguiendo las recomendaciones de la Sociedad Española de Neumología y Cirugía Torácica (SEPAR). Se compararon los resultados con las ecuaciones de Morales de 1997. Resultados: Se presentan los datos de 24 mujeres y 39 hombres (45,94 ± 16,71 años). Existe una diferencia estadísticamente significativa en las mujeres de -19,08 ± 23,57 cmH2O y de -28,13 ± 29,93 cmH2O para la PIM y la PEM, respectivamente, entre el valor observado y el valor predicho. Asimismo, en el caso de los hombres se observó una diferencia estadísticamente significativa de -25,18 ± 24,31 cmH2O para la PIM y de -39,53 ± 44,38 cm H2O para la PEM. Conclusiones: Las ecuaciones predictivas disponibles para las presiones respiratorias máximas sobreestiman considerablemente los valores alcanzados de la PIM y la PEM. Los resultados del presente estudio ponen de manifiesto la necesidad de realizar nuevas ecuaciones de referencia a través de un estudio multicéntrico representativo de toda la población española

Background and aim: The determination of maximal respiratory pressures is a non-invasive process of high clinical value for assessing respiratory muscle strength. The aim is to analyse to what extent the existing predictive equations for the Spanish population are adjusted to the maximal inspiratory and expiratory pressures (MIP and MEP) values observed in a sample of healthy adult subjects. Material and methods: A cross-sectional study was conducted on a sample of 63 healthy subjects recruited from the A Coruña University community using a simple random probabilistic method. Maximal respiratory pressures were performed using a pressure transducer connected to a scuba mouthpiece according to the standards of Spanish Society of Pulmonology and Thoracic Surgery (SEPAR). The results were compared with predictive equations proposed by Morales in 1997. Results: The study included the results from 24 females and 39 males (45.94 ± 16.71 years). Females showed a statically significant difference between the observed and predictive values, with -19.08 ± 23.57 cm H2O and -28.13 ± 29.93 cm H2O for MIP and MEP. A statistically significant difference was also observed for males with -25.18 ± 24.31 cm H2O for MIP and -39.53 ± 44.38 cm H2O for MEP. Conclusions: Predictive equations to calculate the theoretical values of maximal respiratory pressures in a healthy Spanish adult population overestimate considerably the real values of MIP and MEP. The results of this study highlight the need to create new reference equations by conducting a multicentre study representative of the entire Spanish population

Mantenimiento de los efectos tras la rehabilitación pulmonar en pacientes con enfermedad pulmonar obstructiva crónica / Maintenance of effects after pulmonary rehabilitation in patients with chronic obstructive pulmonary disease

Antecedentes/objetivo: La duración de los efectos de la rehabilitación pulmonar (RP) en pacientes con enfermedad pulmonar obstructiva crónica (EPOC) es limitada. El objetivo del estudio fue describir los efectos a corto y largo plazo de varias modalidades de programas clínicos de RP en pacientes con EPOC e identificar los posibles factores influyentes. Pacientes/métodos: Estudio observacional longitudinal retrospectivo. Sujetos con EPOC (n=35) que recibieron uno de los siguientes programas clínicos de RP (8 semanas): PRP1 (entrenamiento aeróbico), PRP2 (entrenamiento aeróbico-fuerza) y PRP3 (entrenamiento aeróbico-fuerza-músculos respiratorios). Variables: capacidad de ejercicio (distancia en la Prueba de Marcha de Seis Minutos, 6MWD), disnea (escala modificada del Medical Research Council, mMRC) y presiones respiratorias (solo PRP3), evaluadas pretratamiento, postratamiento y tras 12 meses. Resultados: Postratamiento mejoró la 6MWD (59,1±27,3 m; p <0,01) y se redujo la escala mMRC (−0,7±0,4; p <0,01). Tras 12 meses desde el postratamiento, se produjo un declive en la 6MWD (−49,8±23 m; p <0,01) y un incremento en la escala mMRC (0,7±0,4; p <0,01). Estos resultados fueron ligeramente superiores en los grupos PRP2 y PRP3, pero sin diferencias significativas (p> 0,05). Un comportamiento similar se observó en las presiones respiratorias. Se analizaron los posibles factores influyentes en el declive en la 6MWD durante el seguimiento. Solo se encontró una correlación significativa e inversa entre el incremento en la 6MWD postratamiento y su declive postseguimiento (r=−0,52; p <0,01). Conclusión: Los programas convencionales de RP en EPOC mejoran la capacidad de ejercicio y la disnea, pero estos beneficios se pierden tras 12 meses sin mantenimiento. El incremento en la 6MWD tras la RP puede ser un factor pronóstico del declive en la tolerancia al ejercicio

Background/objective: The duration of the effects of pulmonary rehabilitation (PR) in patients with chronic obstructive pulmonary disease (COPD) is limited. The aim of the study was to describe the short- and long-term effects of various modalities of clinical PR programs in COPD patients and to identify possible influencing factors. Patients/methods: Retrospective longitudinal observational study was conducted on 35 COPD subjects who received one of the following PR clinical programs (8 weeks): PRP1 (endurance training), PRP2 (endurance-strength training), and PRP3 (endurance-strength-respiratory muscle training). Variables: exercise capacity (distance in the Six-Minute Walk Test, 6MWD), dyspnoea (modified Medical Research Council Scale, mMRC), and respiratory pressures (only PRP3), evaluated pre-treatment, post-treatment and post-12 months. Results: The 6MWD improved post-treatment (59.1±27.3 m, P <.01) and the mMRC Scale was reduced (−0.7±0.4, P <0.01). Post−12 months after treatment there was a decline in 6MWD (−49.8±23 m, P <0.01) and an increase in mMRC Scale (0.7±0.4, P <0.01). These results were slightly higher in the PRP2 and PRP3 groups, but without significant differences (P> 0.05). A similar behaviour was observed in the respiratory pressures. An analysis was made of the possible influencing factors in the decline in 6MWD during follow−up. Only a significant and inverse correlation was found between the increase in post−treatment 6MWD and its post−12 months decline (r=−0.52, P <0.01). Conclusion: Conventional PR programs in COPD improve exercise capacity and dyspnoea, but these benefits are lost after 12 months without maintenance. The increase in 6MWD after PR may be a prognostic factor of decline in exercise tolerance
