Comparison of pre-post operation of cardiac outputs in breast reduction with Simpson’s rule and Teichholz’s formula

Abstract

Aim: This study aims to compare pre- and post-operative cardiac outputs in patients undergoing breast reduction surgery using Simpson's rule and Teichholz's formula. The assessment focuses on ejection fraction (EF), end-systolic volume (ESV), end-diastolic volume (EDV), and stroke volume (SV). Material and Methods: Comparisons across the repeated measurements (pre and post operation values for EF, EDV, ESV and SV) were made by either using Paired Samples t-test or Wilcoxon signed-rank tests. Results: Statistically significant differences were observed in EF, EDV, and SV pre- and post-operative mean scores using the Simpson method (p<0.001, p=0.004, p<0.001, respectively). No significant difference was found for ESV (p=0.061). Using the Teichholz method, significant differences were found in EF, ESV, and SV (p<0.001, p<0.001, p<0.001), but not for EDV (p=0.646). According to Bland-Altman graphics, pre-post measurements were within the limits of agreement in all cardiac outputs. Discussion: Numerous studies in the literature have demonstrated the positive effects of breast reduction surgery on both aesthetic and functional health. Our study makes a significant contribution by revealing the positive impact of this surgery on cardiac performance. Our findings underscore the cardiac benefits of breast reduction surgery and support its role in enhancing overall patient well-being. Future research could investigate in greater detail the long-term cardiovascular benefits and potential respiratory improvements associated with this procedure.
