Safety and improvement in exercise tolerance with interval training vs moderate-intensity continuous training in heart disease patient of very high cardiovascular risk.

Objective: Evaluate safety and effects of training at moderate and high intensity intervals (MIIT, HIIT) compared to continuous moderate intensity training (MICT) in heart disease patient with very high cardiovascular risk (CVR).

Method: Quasi-experimental study of 81 patients in a cardiac rehabilitation (CR) program, after risk stratification, all patients presented at least 2 factors with high CVR. All patients were provided supervised concurrent training: aerobic: initially 2 weeks MICT.

[Correlation of training volume in MET-min/week with the percentage of estimated VO2p gain in patients with chronic heart failure with reduced ejection fraction, undergoing a cardiac rehabilitation program].

Objetivo: La insuficiencia cardiaca (IC) es un síndrome clínico caracterizado por disminución en la capacidad funcional. Los programas de rehabilitación cardiaca y prevención secundaria (PRHCyPS) han mostrado mejorar la calidad de vida y tolerancia al esfuerzo en este grupo de pacientes, pero sus efectos son dependientes del volumen. Nuestro objetivo es evaluar el grado de correlación del volumen de entrenamiento medido en equivalentes metabólicos (MET)-min/semana con el porcentaje de ganancia de consumo pico de oxígeno (VO2p) (MET-carga) posterior a un PRHCyPS en pacientes con IC.
