Abstract
Frailty is common among patients with cardiovascular diseases and is linked to increased risk of adverse outcomes. This article emphasizes the importance of implementation science in tackling frailty, with a special focus on the inclusion of implementation research into cardiovascular trials to improve the uptake of frailty interventions and their eventual integration into routine practice. Through analyzing the barriers and facilitators of implementation, this discussion will explore how conceptual frameworks can guide implementation efforts and provide suggestions for trial designs that facilitate long-term implementation.
