Abstract

Background: Embracing patient viewpoints can enhance the translation of novel therapeutics to clinical settings. This study evaluated the acceptability of using extracellular vesicles (EVs) as a biological therapy for preventing postoperative atrial fibrillation (AF), through engagement with patients, providing insights into their attitudes and information needs.

Methods: Patients participated in prerecorded presentations, virtual focus groups, and surveys to assess their perspectives on EV therapy and determine the factors influencing their acceptance of the intervention.

Results: Participants with postoperative AF experienced prolonged intensive care unit and hospital stays, compared to those of patients with normal heart rhythm. Prior to the presentation, a number of participants were unfamiliar with postoperative AF and biological therapies. However, postpresentation and post-focus group activities resulted in enhanced understanding of the research, with high levels of comprehension reported by all participants. The level of acceptance of EV therapy tended to increase, with a majority expressing willingness to participate in clinical trials and accept the therapy. The focus groups identified and addressed common questions regarding the potential risks and side effects of EVs, their source, dosing, utility for patients with preexisting AF, and the risk of human immunodeficiency virus (HIV) contraction or allergic reactions.

Conclusions: The study highlights the importance of providing education, involving the patient's circle of care, and addressing patient concerns, to promote acceptance of therapies such as EV therapy for postoperative AF.

Clinical Trial Registration: NCT05032495.
