Is Monocyte/HDL Ratio a Predictor of Mortality in Aortic Valve Surgery

In this study, the investigators aimed to determine whether the preoperative Monocyte/HDL ratio would be a predictor of postoperative mortality and morbidity in patients who underwent aortic valve replacement due to aortic stenosis.

Inclusion Criteria:be over the age of 18, ASA II-IV Patients scheduled for cardiac surgery due to on-pomp aortic valve replacementExclusion Criteria:emergency operations, off pump)pumpless surgery, revision (repetitive) operations, those with signs of acute infection, those with autoimmune disease, those with severe renal (serum creatinine >2.0 mg/dl) disease, those with severe hepatic disease, those with suspected malignancy, patients where data variables cannot be saved due to technical problems.
