People with heart failure often perceive difficulties performing physical activities due to their symptoms. However, physical activity is beneficial and recommended. Therefore, it is a need for interventions supporting patients to increase their physical activity in everyday life.

This study aims to investigate the feasibility of a mobile exergame intervention for patients with heart failure.

Nine Swedish patients with heart failure, seven male and two female, median age 73 years (range 63-81) participated. Patients downloaded the exergaming application "Heart Farming" on their private smartphones. Patients were advised to increase daily walking based on their physical condition. Patients received introduction and telephone conversations on a predetermined schedule. Feasibility areas of Acceptability, Demand, Implementation, and Practicality were examined by interviews and data downloaded from the application.

Patients used Heart farming for one month, their goal of daily walks was in mean 704 meters (range 417-900 meters). Patients increased daily walks and experienced improved health. The individual conversations were perceived supportive and encouraging. Heart farming was perceived easy to learn, use and adjustable to individual needs.

The study confirmed the impact of encouragement, and importance of tailoring the intervention to patients' personal situation, to achieve regularly daily walks.
