Exercise is a major component in primary and secondary prevention of cardiovascular disease and is an important entity in improving cardiovascular health. Significant limitation in physical function coexists with heart failure. Several factors promote exercise intolerance in heart failure, including upregulated neurohormonal milieu and nutritional deficiencies, both of which can lead to muscle wasting and cachexia. Durable mechanical circulatory support, including left ventricular assist device (LVAD) and total artificial heart (TAH), can significantly improve morbidity and mortality in select patients with end-stage cardiomyopathy. Durable mechanical support significantly improves morbidity and mortality in select patients with end-stage cardiomyopathy. Left ventricular assist device (LVAD) and total artificial heart (TAH) are considered durable mechanical circulatory support. LVAD has been used both as a bridge to cardiac transplant and as a destination device, while TAH is generally considered a bridge to heart transplantation device. Several studies have demonstrated safety and benefits of exercise in patients with heart failure. Both low body mass index (BMI) and low albumin among advanced heart failure patients at the time of LVAD or TAH implantation increase risk of complication and rehospitalization. Optimization of frailty with exercise training (ET) through a cardiac rehabilitation program (CR) in heart failure patients improves functional status and quality of life. Improved frailty and nutritional status prior to durable mechanical circulatory support implantation have improved outcomes. Lower posthospital complications and reduced hospital stay have been reported among patients undergoing cardiac rehabilitation (CR) and supervised exercise training (ET) prior to scheduled durable mechanical circulatory support implantation. Continued ET post LVAD implantation should be monitored following hospital discharge to improve outcomes in HF patients. However, several barriers exist for referral of HF patients to CR and addressing these factors may be favorable in improving participation of heart failure patients in CR programs. Continued vigilance of patients’ exercise routines and increasing education and awareness among providers caring for HF patients regarding CR programs can have a positive impact on overall outcomes in HF patients.
