# Cardiac Rehabilitation After Left Ventricular Assist Device Implantation: A Narrative Review

## TL;DR

This paper reviews how cardiac rehabilitation improves outcomes for patients with left ventricular assist devices, highlighting its safety and effectiveness.

## Contribution

The paper emphasizes the importance of early cardiac rehabilitation for LVAD patients and outlines unique considerations for its implementation.

## Key findings

- Cardiac rehabilitation improves functional capacity and reduces heart failure-related hospitalizations in LVAD patients.
- Exercise-based rehabilitation is safe and may be linked to lower mortality, though evidence is not yet conclusive.
- Unique challenges like monitoring LVAD components and detecting pulse during CPR must be addressed in rehabilitation programs.

## Abstract

Over the past decade, given safety, reduced heart failure-related hospitalizations, and, above all, 5-year mortality rates nearly identical to those of heart transplants, left ventricular assist devices (LVADs) have increasingly become a treatment option for patients with advanced heart failure. However, improvements in functional capacity after LVAD implantation are minimal or modest, depending on pre-implantation right ventricular function, the patient’s hemodynamic status, the optimization of guideline-directed medical therapy, and noncardiac factors (physical deconditioning, skeletal muscle alterations, anemia, and alterations in alveolar gas exchange). Therefore, cardiac rehabilitation (CR) is a fundamental element from the early stages after LVAD implantation, as it is not only safe but also highly effective, leading to improved functional capacity and fewer episodes of worsening heart failure, and may be associated with reduced mortality. To perform safe and effective CR in patients with LVADs, it is crucial to account for the unique issues in this group. This includes the difficulty of detecting an arterial pulse with standard tools during CPR and the importance of closely monitoring the transmission line and LVAD controller to prevent unintended damage. Overall, the clinical trial indicates that exercise-based CR has the potential to improve functional capacity. Furthermore, some data suggest that CR is associated with fewer HF-related hospitalizations and may be linked to lower mortality; however, there is no consensus on this matter, partly because most studies supporting this assertion are observational.
