Background Despite its benefits, cardiac rehabilitation (CR) participation rates remain subpar. Telehealth lifestyle interventions have emerged as modalities to enhance CR accessibility. Virtual-world (VW) technology may provide a means to increase CR use. Objectives This pilot study assessed the feasibility and acceptability of a VW-based CR program as an extension to medical center-based CR. Our goal is to apply the study results toward the design of a patient-centered VW platform prototype with high usability, understandability, and credibility. Methods Patients ( n = 8, 25% women) recently enrolled in outpatient CR at Mayo Clinic, Rochester, Minnesota participated in a 12-week, VW health education program and provided feedback on the usability, design and satisfaction of the intervention at baseline and completion. A mixed-methods approach was used to analyze the participant perceptions of the intervention. Results Overall, there were positive participant perceptions of the VW experience. There was unanimous high satisfaction with the graphical interface appearance and ease of use. Participants placed value on the convenience, accessibility, and social connectivity of the remote program as well as the novelty of the simulation platform presentations, which aided in memorability of key concepts. Greater than 80% of participants reported that the program improved their health knowledge and helped to maintain better health habits. Conclusions Our pilot study revealed the feasibility and acceptability of an innovative VW-based CR program among cardiac patients. This novel delivery method for CR has the potential to influence healthy lifestyle change and to increase accessibility to vulnerable populations with higher cardiovascular disease burdens.

Background: Cardiovascular (CV) disease is the leading cause of death in U.S. women. Although women are becoming more aware of CV disease, there remains a dichotomy between awareness and perceived risk. We sought to characterize this dichotomy in women attracted to a CV health–screening event, in order to improve strategies to reduce CV risk. Methods: During CV health events held in Rochester, Minnesota, from 2007 through 2011, 294 women underwent screening for blood chemistry, body mass index, and blood pressure. Participants also completed surveys about knowledge of CV disease, risk factors, and perceived risk. Risk level was determined from the 2011 American Heart Association Effectiveness-Based Guidelines for Women. Results: Among participants (age, mean [standard deviation], 53 [15.3] years; white, 98%), 99% were aware that CV disease is the leading cause of death in women. Almost half (47%) perceived themselves to be at personal risk, although 65% were determined to be “at risk” and 12% to be at “high risk” according to guidelines, while 22% were uncategorized. Of the 228 participants “at risk” or “high risk,” 48% and 21%, respectively, did not perceive themselves to be at any risk. Conclusions : Women attracted to CV health events were aware that CV disease is the leading cause of death for women. However, the magnitude of awareness did not directly translate into perception or understanding of actual personal risk. To decrease the rate of CV disease in women, continued efforts are needed to personalize the importance of, and the methods for reducing, CV risk factors.
