Key result
In elderly patients undergoing cardiovascular surgery, low perioperative hemoglobin and albumin, and high glucose and urea levels were significantly associated with increased postoperative complications and 30-day mortality (p<0.005).
Why the study?
With increasing numbers of hospitalized elderly patients, more specific information is needed regarding prognosis following cardiovascular surgery.
Do preoperative and postoperative laboratory parameters predict postoperative complications and 30-day mortality in patients aged 65 and over undergoing cardiovascular surgery?

p-value: p=<0.005
Closely monitoring and optimizing nutritional status, blood glucose, and renal function parameters in elderly patients undergoing cardiovascular surgery may help reduce postoperative complications and mortality.
Lab parameters identify high-risk elderly CV surgery patients; hypothesis-generating and requires prospective validation before guiding care.
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).

Özay et al. (2021) conducted a cross-sectional in Cardiovascular surgery (n=346). Perioperative laboratory abnormalities (anemia, hypoalbuminemia, hyperglycemia, uremia) vs. Normal laboratory values was evaluated on Postoperative complications and 30-day mortality (p=<0.005). In elderly patients undergoing cardiovascular surgery, low perioperative hemoglobin and albumin, and high glucose and urea levels were significantly associated with increased postoperative complications and 30-day mortality (p<0.005).
