Smartheart CABG edu: First prototype and preliminary evaluation

The paper reports on the preliminary evaluation of the SmartHeart CABG Edu Android app. The app was conceived to be an innovative and up-todate tool for patient education, the first of its kind in the Italian context. In particular, the app was developed to provide (i) educational material for patients about to undergo Coronary Artery Bypass Graft (CABG) surgery and (ii) a set of selfassessment tools concerning health status (i.e., BMI calculator, LDL cholesterol calculator and anxiety assessment tool) and usability (i.e., SEQ and SUS). The educational material informs patients on Coronary Artery Disease, on the CABG surgery clinical pathway and on the healthy lifestyle behaviors to implement in order to enhance self-care, while the self-assessment tools stimulate patients to check on progress in their health status. The evaluation concerning the app usability has given overall positive rating results, whereas further research with a higher number of patients is advisable in order to evaluate pre-operative anxiety more significantly.
