Short physical performance battery in the pre and postoperative myocardial revascularization surgery in older adults: Reliability, hemodynamic responses, subjective perceived exertion, and adverse events

ABSTRACT

Introduction

The Short Physical Performance Battery (SPPB) may be feasible for evaluating older adults undergoing myocardial revascularization surgery (MRS). However, it is necessary to verify its measurement properties and safety to use it for clinical practice.

Objective

To investigate the reliability, hemodynamic responses, subjective perceived exertion (SPE), and adverse events during and after SPPB in older adults undergoing MRS.

Materials and methods

A cross-sectional and methodological study conducted with 85 older adults in the pre and postoperative periods of MRS. The hemodynamic responses [heart rate (HR) and systolic blood pressure (SBP)], SPE, and adverse events were evaluated before and after the SPPB. Two researchers performed the inter-rater reliability within a 30-minute interval, while the interval between measures for intra-rater reliability was 24 hours. The Friedman test was used to analyze hemodynamic and SPE responses. The intraclass correlation coefficient (ICC) and the coefficient variation of method error (CV_ME) were used for the reliability analysis.

Results

Increases in HR (p < 001), SBP (p < 0.01), and SPE (p < 0.01) were observed immediately after the SPPB. Only seven volunteers reported minor adverse events. Regarding reliability results, ICC_(3,1) for intra-rater reliability varied from 0.66 to 0.87 and CV_ME from 4.80 to 8.82%. For inter-rater reliability, ICC_(2,1) varied from 0.66 to 0.91 and CV_ME from 4.04 to 9.02%.

Conclusion

The SPPB increased the HR, SBP, and SPE immediately after its execution. In addition, it showed light changes in SPE, few adverse events, and good reliability in older adults in the pre and postoperative MRS period.
