ABSTRACT

Introduction: recent demographic changes have meant that more and more frail patients undergo surgery. The relationship between frailty, measured by dynamometry, and morbidity and mortality in cardiac surgery has not been fully studied. Objective: determine the usefulness of frailty, as measured by dynamometry, as a predictor of morbidity and mortality in geriatric patients with low surgical risk undergoing cardiac surgery. Material and methods: a prospective cohort study including 65 geriatric patients with moderate surgical risk undergoing elective cardiac surgery with cardiopulmonary bypass. The patients underwent preoperative dynamometry to determine their frailty, whose relationship with postoperative morbidity and mortality was evaluated. Sensitivity, specificity, predictive values, positive and negative probability coefficients, Cronbach's alpha coefficient and area under the ROC curve were calculated. The data were processed with SPSS v-24.0. Results: the evaluation of the calibration component showed that it fitted our sample (Cronbach's alpha coefficient 0.79). The evaluation of the discrimination component showed that it was able to distinguish between risk of morbidity (0.625) and risk of mortality (0.597). Conclusion: frailty, measured by dynamometry, is a useful predictor of morbidity and mortality in elderly patients with low surgical risk undergoing cardiac surgery.
