Assessment of the Early Disabling Effects of Coronary Artery Bypass Graft Surgery Using Direct Measures of Physical Function.

ABSTRACT:

Purpose

Coronary artery bypass graft (CABG) surgery is an important treatment option in patients with coronary artery disease. Despite its beneficial effects, CABG surgery and its subsequent hospitalization may reduce physical functional capacity in patients, contributing to physical disability. Our objective was to assess the early disabling effects of CABG surgery and its subsequent hospitalization using direct measurements of physical function.

Methods

Patients (n = 44) were assessed pre-surgery and at hospital discharge for physical function using the Short Physical Performance Battery (SPPB) and self-reported physical and mental health by questionnaire.

Results

The total SPPB score (P < .001) and all of its components (P < .01-.001) decreased markedly following CABG surgery and hospitalization, with greater reductions in total SPPB score (P < .05) and gait speed (P < .01) in patients with higher body mass index. While CABG surgery and hospitalization reduced patient-reported physical function, changes in these indices largely did not correlate with changes in SPPB outcomes.

Conclusion

Our results show the early disabling effects of CABG surgery and hospitalization on directly measured physical function, and that patients with higher body mass index had greater reductions. In addition, our results underscore the need to perform direct measurements of physical function to describe reductions in physiological functional capacity. These findings suggest the need for inpatient rehabilitation or early mobility programs to address this decline in physical function.
