Abstract:

Currently, coronary artery bypass greft surgery (KABG) is intensively performed. Hemotological parameters have been to be a indicator that can be used in determining postoperative mortality, morbidity and long-term survival of patients with CABG. This study examined whether the preoperative hematological parameters in patients with CABG, the neutrophil/lenphocytes (N/L) ratio, the erythrosite distribution volume (RDW) value and the preoperative thrombocytes value and the postoperative thrombocytes value differences have a relationship with postoperative mortality, morbidity and other causes that extend the hospital stay. Tools and Methods: Non-additional heart disease and non-additional surgery involves the retrospective examination of post-chirurgical records of 670 incidents applied coronary arter bypass greft surgery under elective conditions due to ischemic heart disease. Results: The study included 151 women (22.5 percent), 519 men (77.5 percent), a total of 670 facts. Atrial fibrillation (AF) after CABG occurred at 22.5%, major unwanted cardiovascular effects (MACCE) at 6.7%, mortality at 4.6%. The preoperative high N/L ratio was found associated with developing AF and adverse effects after CABG (P<0.001 and P=0.001). The preoperative high RDW value was found to be associated with the developing AF after KABG (P=0.005). The difference between postoperative and preoperative thrombocytes was found to be associated with developing post-CABG mortality (P<0.001). On the postoperative 7th day, a 1 unit (103 mm3) increase compared to preoperative thrombocytes observed a 3% decrease in mortality risk (P<0.001). The more detailed assessment of preoperative hematological parameters contributes to the prediction of mortality and morbidity, and with extensive studies to be done, these parameters will increase the reliability of these systems by incorporating them into the risk scores systems.
