Exergaming in patients with a left ventricular assist device: a feasibility study

Area of Science:

• Cardiology
• Rehabilitation Medicine
• Digital Health

Background:

• Patients with left ventricular assist devices (LVADs) require physical activity for health benefits, but exercise is often limited by device-specific challenges.
• Exergaming presents a novel approach to facilitate physical activity in individuals with chronic diseases.

Purpose of the Study:

• To evaluate the feasibility and safety of using exergames for physical activity in patients supported by LVADs.
• To assess the impact of exergaming on exercise capacity and quality of life in LVAD patients.

Main Methods:

• A 4-week exergaming program using the Nintendo Wii console was implemented with 11 LVAD patients.
• Participants engaged in 30 minutes of exergaming, 5 days a week.
• Exercise capacity was measured using the 6-minute walk test (6MWT), and feasibility/safety were assessed via interviews and diaries.

Main Results:

• The 6MWT distance significantly increased after the 4-week program (mean increase of 24m, P=0.023).
• Patients reported improvements in quality of life, indicated by higher scores on Cantril's Ladder of Life and lower scores on the Minnesota Living with Heart Failure Questionnaire (MLHFQ).
• No LVAD-related safety issues were reported during the exergaming intervention.

Conclusions:

• Exergaming is a safe and feasible method to promote physical activity in LVAD patients.
• This intervention demonstrates potential for enhancing exercise capacity and improving quality of life in this population.
• Further large-scale studies are recommended to confirm these findings.
