Abstract
Antecedentes: la rehabilitación cardiaca basada en ejercicio es una estrategia de tratamiento para los pacientes con falla cardiaca. En la actualidad hay controversia sobre su efecto en parámetros centrales y hemodinámicos de la función ventricular. Objetivo: evaluar el efecto de un programa de rehabilitación cardiaca basada en ejercicio sobre la capacidad física, la función cardiaca y la calidad de vida en pacientes con falla cardiaca. Diseño y métodos: estudio de intervención en pacientes con falla cardiaca estadio C, clase funcional NYHA II-III, a quienes se les hicieron pruebas funcionales, ecocardiografía y concentración sérica de la porción NT-proPNC y, además, se les aplicó un cuestionario de calidad de vida, antes de un programa de rehabilitación cardiaca basada en ejercicio y doce semanas después de éste. Resultados: se incluyeron 22 pacientes con una edad promedio de 59 ± 9 años. De ellos, 17 (77,3%) fueron hombres y 20 (90,9%) tenían enfermedad coronaria. El consumo de oxígeno máximo indirecto (VO2) aumentó de 26,4 ± 6,4 mL.kg-1.min-1 a 34,5 ± 7,7 mL.kg-1.min-1 en promedio (p<0,001) y la distancia alcanzada en la prueba de caminata de los seis minutos se incrementó de 438 ± 67,9 metros a 513 ± 83,4 metros en promedio (p<0,001). La fracción de expulsión aumentó de 32,68 ± 8,8% a 38,82 ± 9,16% (p<0,001). Hubo mejoraría en la calidad de vida en el dominio de "cambio de salud en el tiempo" (p<0,05). Conclusión: los pacientes con falla cardiaca que se intervienen con un programa de rehabilitación cardiaca basada en ejercicio durante doce semanas, mejoran su capacidad funcional, la función sistólica y la calidad de vida.
Background: exercise-based cardiac rehabilitation is a strategy treatment in patients with heart failure. Currently there is controversy about its effect on central and hemodynamic parameters of ventricular function. Objective: to evaluate the effect of an exercise-based cardiac rehabilitation program on physical capacity, cardiac function and quality of life in patients with heart failure. Design and Methods: intervention study in patients with heart failure stage C, NYHA functional classes II-III that were submitted to functional tests, echocardiography and plasma levels of NT-pro-BNP, and also answered a questionnaire on quality of life before and twelve weeks after a cardiac rehabilitation program based on exercise. Results: 22 patients with mean age 59 ± 9 years old were included. 17 (77,3%) were men and 20 (90,9%) had coronary heart disease. The indirect maximum oxygen consumption (VO2) increased on average from 26.4 ± 6.4mL.kg-1.min-1 to 34.5 ± 7.7 mL.kg-1.min-1 (p<0.001) and the distance reached in the 6–minute walking test increased on average from 438 ± 67.9 meters to 513 ± 83.4 meters (p<0.001). The ejection fraction increased from 32.68 ± 8.8% to 38.82 ± 9.16% (p<0.001). There was improvement in the quality of life in the domain of «health change over time» (p<0.05). Conclusions: Patients with heart failure who are involved in a cardiac rehabilitation program based on exercise for twelve weeks improve their functional capacity, systolic function and quality of life.
