Longitudinal functional recovery after geriatric cardiac surgery

Area of Science:

• Geriatric Medicine
• Cardiovascular Surgery
• Rehabilitation Medicine

Background:

• Major cardiac surgery poses risks to functional and cognitive status in older adults.
• Assessing longitudinal recovery is crucial for this demographic.
• Pilot study to evaluate feasibility of longitudinal outcome assessment.

Purpose of the Study:

• To assess the feasibility of longitudinal functional and cognitive outcome evaluation in older adults undergoing major cardiac surgery.
• To identify predictors of postoperative recovery.

Main Methods:

• Longitudinal assessment of functional and cognitive status in patients aged ≥ 65 years.
• Preoperative and 4-6 week, 4-6 month postoperative follow-ups.
• Linear regression and longitudinal modeling used to analyze changes and predict recovery, adjusting for comorbidity.

Main Results:

• 62 patients (mean age 74.7 years) completed the study.
• Preoperative activities of daily living (ADL) impairment correlated with poorer functional recovery at 4-6 weeks (P < 0.05).
• No significant difference in recovery detected by 4-6 months; preoperative cognition and physical activity were not associated with changes.

Conclusions:

• Integrating preoperative and postoperative function/cognition evaluation is feasible in older surgical patients.
• Preoperative ADL impairment can identify patients needing enhanced postoperative planning for self-care assistance.
• Early postoperative support is critical for patients with baseline functional deficits.
