Abstract :It has been stated that red blood cell distribution width (RDW) and neutrophil-lymphocyte ratio (NLR) have prognostic value in cardiovascular surgery, as well as various clinical conditions. This study aimed to determine whether preoperative NLR and RDW values had an effect on postoperative mortality and morbidity in patients undergoing isolated heart valve surgery. Methods: This study was retrospectively conducted by examining the medical records of patients who underwent isolated heart valve replacement surgery between 2016 and 2020. Preoperative RDW and NLR values, postoperative extubation, mechanical ventilation, intensive care unit stay, and hospital stay, presence of postoperative cerebrovascular disease (CVD) and new-onset atrial fibrillation (AF), and dialysis requirement were recorded. The data of 68 patients were evaluated. In all the patients, the mean preoperative NLR value was 4.67±3.67, and the mean preoperative RDW value was 15.06±2.19. The NLR and RDW values were determined as 4.91(p=0.756) and 15.48 (p=0.032); respectively in the patients that developed postoperative AF, 3.34 and 17.56, respectively in those that developed postoperative CVD, and 9.26 and 14.93, respectively in those that required dialysis. Although preoperative the NLR and RDW values were high among the patients undergoing heart valve replacement surgery, it is not possible to state that these two markers have prognostic value for postoperative adverse events in this patient population.
