Impacto de la rehabilitación cardiaca en pacientes con falla cardiaca de origen isquémico Impact of heart rehabilitation in patients with heart failure of ischemic origin
Abstract
OBJETIVO: establecer el impacto de la rehabilitación cardiaca en pacientes con falla cardiaca de origen isquémico con fracción de eyección menor del 40% en términos de síntomas, a través de la percepción subjetiva de la escala de Borg, VO2, MET y distancia en millas antes y al finalizar la terapia de rehabilitación cardiovascular. DISEÑO: estudio de cohorte concurrente. POBLACIÓN: 224 pacientes que ingresaron al programa de rehabilitación cardiaca de La Fundación Clínica Abood Shaio en el periodo comprendido entre el 10 de diciembre de 2004 y el 2 de mayo de 2008. MEDICIONES: se revisó la base de datos de rehabilitación cardiaca clasificando los parámetros de actividad física al ingreso y al egreso de la terapia. RESULTADOS: en el impacto de la terapia de rehabilitación cardiaca al inicio, 63% de los pacientes se encontraba en las escalas uno y dos de Borg modificada, y al final 85% (p OBJECTIVE: to establish the impact of heart rehabilitation in patients with heart failure of ischemic origin with ejection fraction <40% in terms of symptoms by subjective perception of the Borg scale, VO2, MET and distance in miles before and at the end of cardiovascular rehabilitation therapy. DESIGN: concurrent cohort study. POPULATION: 224 patients admitted to the Abood Shaio Clinic Foundation cardiac rehabilitation program in the period from December 10, 2004 to May 2, 2008. MEASUREMENTS: it was reviewed the database of cardiac rehabilitation classifying physical activity parameters on admission and at discharge from therapy. RESULTS: with regard to the impact of cardiac rehabilitation therapy at baseline, 63% of patients were in the modified one and two Borg scale and at the end, 85% of patients (p <0.001) was placed on the three and four scales; VO2 at baseline was 7.79 and to the end 19.04 (p <0.001); the METS at the beginning was 2.22 and at the end 5.44 (p <0.001) and distance in miles per hour at the beginning was 1, 33 and at the end 2.58 (p <0.001). CONCLUSIONS: it was found that cardiac rehabilitation had a significant impact in patients with ischemic heart failure with left ventricular ejection fraction <40% in terms of subjective perception of symptoms in the Borg scale, indirect VO2, METS and distance in miles per hour.
