Effects of Exergaming to Reduce Sedentary Time in Inactive Patients With Heart Failure

Rationale: Heart failure (HF) is an increasing global health concern with over 20 million patients worldwide. A decrease in sedentary time can have beneficial effects for a growing group of inactive patients with HF. The use of exergames (games to improve physical activity) is promising for people who are home bound and physically inactive. Such a gaming activity should be attractive, tailored to preferences and to capacity. Objective: To determine the effect of tailored exergaming for inactive patients with HF to reduce their sedentary time, improve their daily physical activity, exercise capacity, decrease frailty and improve health-related quality of life. Study design: A pilot study and a multicentre, open-label 1:1 randomised clinical trial with 6 months follow-up. Study population: Adult patients with symptomatic HF: n= 20 for the pilot study and n=600 for the main study Intervention: On a background of standard guideline-directed medical therapy patients will be randomised to tailored activity advice (control) or the Heart-Exergame (Heart-eXg) intervention for a period of 3 months. Patients randomised to the Heart-eXg group will receive an exergame with feedback and tailoring to adapt the exergaming advice. Patients will also be able to play with a person in their own network. Main study parameters/endpoints: Primary endpoint is sedentary time (actigraphy). Secondary outcomes are daily physical activity, submaximal exercise capacity, physical frailty, health-related quality of life. This study will gain insight into the effects of using an exergame that is easily applicable and affordable. Given the vast growing target population of patients with HF worldwide, and the simplicity of the intervention, potentially millions of patients may benefit from the results of this study.
