Factibilidad y resultados de un programa de rehabilitación cardiaca intensiva. Perspectiva del estudio aleatorizado MxM (Más por Menos) / Feasibility and results of an intensive cardiac rehabilitation program. Insights from the MxM (Más por Menos) randomized trial

Introducción y objetivos: Los programas de rehabilitación cardiaca (PRC) engloban intervenciones encaminadas a mejorar el pronóstico de la enfermedad cardiovascular influyendo en la condición física, mental y social de los pacientes, pero no se conoce su duración óptima. Nuestro objetivo es comparar los resultados de un PRC estándar frente a otro intensivo más breve tras un síndrome coronario agudo, mediante el estudio Más por Menos. Métodos: Diseño prospectivo, aleatorizado, abierto, enmascarado a los evaluadores de eventos y multicéntrico (PROBE). Se aleatorizó a los pacientes al PRC estándar de 8 semanas u otro intensivo de 2 semanas con sesiones de refuerzo. Se realizó una visita final 12 meses después, tras la finalización del programa. Se evaluó: adherencia a la dieta, esfera psicológica, hábito tabáquico, tratamiento farmacológico, capacidad funcional, calidad de vida, parámetros cardiometabólicos y antropométricos, eventos cardiovasculares y mortalidad por cualquier causa durante el seguimiento. Resultados: Se analizó a 497 pacientes (media de edad, 57,8±10,0 años; el 87,3% varones; programa intensivo, n=262; estándar, n=235). Las características basales de ambos grupos eran similares. Al año, más del 93% había mejorado en al menos 1 MET el resultado de la ergometría. Además, la adherencia a la dieta mediterránea y la calidad de vida mejoraron significativamente con el PRC, sin diferencias significativas entre grupos. Los eventos cardiovasculares ocurrieron de manera similar en ambos grupos. Conclusiones: La PRC intensiva podría ser tan efectiva como la PRC estándar en lograr la adherencia a las medidas de prevención secundaria y ser una alternativa para algunos pacientes y centros.

Introduction and objectives: Cardiac rehabilitation programs (CRP) are a set of interventions to improve the prognosis of cardiovascular disease by influencing patients’ physical, mental, and social conditions. However, there are no studies evaluating the optimal duration of these programs. We aimed to compare the results of a standard vs a brief intensive CRP in patients after ST-segment elevation and non–ST-segment elevation acute coronary syndrome through the Más por Menos study (More Intensive Cardiac Rehabilitation Programs in Less Time). Methods: In this prospective, randomized, open, evaluator-blind for end-point, and multicenter trial (PROBE design), patients were randomly allocated to either standard 8-week CRP or intensive 2-week CRP with booster sessions. A final visit was performed 12 months later, after completion of the program. We assessed adherence to the Mediterranean diet, psychological status, smoking, drug therapy, functional capacity, quality of life, cardiometabolic and anthropometric parameters, cardiovascular events, and all-cause mortality during follow-up. Results: A total of 497 patients (mean age, 57.8±10.0 years; 87.3% men) were finally assessed (intensive: n=262; standard: n=235). Baseline characteristics were similar between the 2 groups. At 12 months, the results of treadmill ergometry improved by ≥ 1 MET in ≥ 93% of the patients. In addition, adherence to the Mediterranean diet and quality of life were significantly improved by CRP, with no significant differences between the groups. The occurrence of cardiovascular events was similar in the 2 groups. Conclusions: Intensive CRP could be as effective as standard CRP in achieving adherence to recommended secondary prevention measures after acute coronary syndrome and could be an alternative for some patients and centers.
