Frailty, Physical Capacity and Lung Function in Postoperative Cardiac Surgery Patients

Assessment of Frailty, Physical Capacity and Lung Function in Postoperative Cardiac Surgery Patients: an Observational and Prospective Clinical Study

The goal of this observational and prospective study is to investigate changes in physical performance, lung function, and respiratory and peripheral muscle strength in patients during the postoperative period following coronary artery bypass grafting (CABG) and valve replacement surgery..

This study aims to investigate the physical changes in patients undergoing myocardial revascularization surgery and valve replacement. It will observe alterations in physical performance, lung function, and muscle strength during the postoperative period. The study, observational and prospective, will include individuals aged ≥18 scheduled for these surgeries, evaluating them preoperatively, post-intensive care unit discharge, and before hospital discharge. Assessments involve tests like the Short Physical Performance Battery, 1-minute sit-to-stand test, Clinical Frailty Scale, manovacuometry, dynamometry, and spirometry to identify frailty and measure muscle and lung function. The study also aims to explore predictive variables for functional loss and mortality during hospitalization.

Inclusion Criteria

• Age ≥ 18 years
• Both genders
• Elective coronary artery bypass grafting surgery
• Elective Heart valve surgery
• Absence of cognitive or peripheral motor impairment that prevents the performance of functional tests in the preoperative period.

Exclusion Criteria:

• Surgeries performed via lateral thoracotomy or minithoracotomy
• Reoperation for any reason
• Presence of cognitive or peripheral motor impairment that prevents the performance of functional tests in the postoperative period.
