Morbidity and Mortality Markers in Elderly Patients with Cardiovascular Surgery

Abstract

Objective: In recent years, as a result of increased average longevity, the number of hospitalized elderly patients has been increasing. Today, although many parameters are used to determine the prognosis of hospitalized patients, more specific information about elderly patients is required. This study aims to investigate the effect of preoperative and postoperative parameters on postoperative complications and mortality among patients aged 65 and over who underwent cardiovascular surgery. Methods: Demographic data, preoperative and postoperative hemoglobin, neutrophil/lymphocyte ratio, mean platelet volume, erythrocyte distribution width, platelet, glucose, urea, creatinine, albumin values and postoperative data were recorded. Results: When the preoperative risk factors for postoperative complications and mortality were evaluated, low preoperative hemoglobin and albumin values and high blood urea and glucose levels were statistically significant (p <0.005). Low postoperative hemoglobin, albumin values, platelet counts, and and high glucose, urea and creatinine values were found to be significant markers of postoperative complications (p <0.005). When preoperative risk factors were evaluated in terms of postoperative 30-day mortality, preoperatively decreased hemoglobin and albumin, increased urea , decreased postoperative hemoglobin, albumin levels, platelet counts, and increased glucose, urea and creatinine values were statistically significant (p <0.005). Conclusion:We believe that closely monitoring the nutritional status of elderly patients, providing them with dietary supplementation for deficient parameters, and keeping blood glucose, urea, and creatinine at optimum levels could help us to decrease hospital stay, mortality-morbidity, and total economic cost.
