Cardiac Diseases Requiring Surgery

This is a prospective cohort study aiming to construct a prediction model for postoperative cognitive dysfunction (POCD) in elderly cardiac patients. We plan to enroll elderly patients aged ≥65 years undergoing cardiac surgery. Peripheral blood samples and functional magnetic resonance imaging (fMRI) data will be collected at baseline and key time points post-surgery. The primary objectives are to identify novel peripheral blood protein biomarkers for POCD, explore the correlation between fMRI characteristics and POCD, and establish a reliable early prediction model to improve perioperative management and reduce the incidence of POCD in elderly cardiac surgical patients.

The primary objective of this two-year research project is to investigate the status of activity fear, its related factors, and prognosis in cardiac surgery patients in the first year. Subsequently, the study aims to develop a comprehensive intervention strategy combining exercise with cognitive-behavioral approaches tailored for cardiac surgery patients and assess the effectiveness of this intervention on activity fear, prognosis, and quality of life in the second year.
