Changes in frailty status after cardiac surgery. A prospective cohort study

Area of Science:

• Gerontology
• Cardiovascular Surgery
• Geriatric Medicine

Background:

• Frailty is increasingly recognized in cardiac surgery patients.
• Preoperative frailty reduction is a focus, but postoperative effects are unknown.

Purpose of the Study:

• To investigate the impact of major cardiac surgery on the frailty status of older adults.
• To analyze changes in frailty scores and transitions six months post-surgery.

Main Methods:

• Prospective cohort study of 137 patients aged 70+ undergoing major cardiac surgery.
• Frailty assessed preoperatively and 6 months postoperatively using Fried Scale and Clinical Frailty Scale (CFS).

Main Results:

• Prevalence of frailty was 27.5% (Fried Scale) and 11% (CFS) preoperatively.
• Up to 50% of frail patients improved their status post-surgery.
• Significant reduction in overall frailty burden observed six months after surgery (p<0.01).

Conclusions:

• Frailty is a dynamic condition significantly reducible after cardiac surgery.
• Cardiac pathology appears to be a key contributor to preoperative frailty.
