Key result
Exercise-based interventions show some evidence of improving frailty after cardiac surgery.
Why the study?
Frail patients have poorer cardiac surgery outcomes, and interventions targeting frailty may improve surgical recovery.
Do interventions targeting frailty improve frailty in adults undergoing cardiac surgery?
Systematic Review (n=5)
Do interventions targeting frailty improve frailty in adults undergoing cardiac surgery?
There is limited but positive evidence that exercise-based interventions can improve frailty in adults undergoing cardiac surgery, though definitions and methods vary widely.
Supports exercise-based frailty interventions after cardiac surgery; extends limited evidence but heterogeneity warrants standardized trials.
Frail patients have poorer cardiac surgery outcomes. Interventions targeting frailty may improve surgical recovery. This study explored interventions that specifically target frailty in patients undergoing cardiac surgery. A systematic review was conducted, searching multiple electronic databases from January 2010 to May 2022. Studies applying an intervention targeting frailty (measured using a validated tool) in adults undergoing cardiac surgery were included. Data extraction and quality assessments were undertaken by two authors. From 2726 identified papers, five studies were included in the final review. Studies varied in their definitions of frailty, methods and intervention components. All included an exercise component, but these varied in frequency, length and content. Three studies reported an improvement in frailty. This review identified that there is some evidence that frailty is improved after an exercise intervention. Further research should focus on the multifaceted nature of frailty, the degree to which frailty is reversed by interventions and the effectiveness of such interventions specifically for women.

Cook et al. (2023) conducted a systematic review in Frailty in patients undergoing cardiac surgery (n=5). Interventions targeting frailty (including exercise) was evaluated on Improvement in frailty. Interventions targeting frailty, which all included an exercise component, showed some evidence of improving frailty after cardiac surgery in three of the five included studies.
