Study summary

This study aims to investigate the relationship between preoperative Cardiac Power Output (CPO), which reflects the pumping capacity of the heart, and the P-POSSUM score, a widely used surgical risk assessment tool, in patients aged 65 years and older undergoing abdominal surgery. Simple and non-invasive measurements performed in the preoperative period will be used to obtain CPO values and to evaluate whether these measurements are helpful in predicting postoperative morbidity and mortality. No additional procedures beyond routine clinical care will be performed as part of this observational study. The findings of this study may contribute to a more accurate assessment of surgical risk and help improve patient safety in the perioperative period.
