The possibility of predicting cardiac complications in thoracic oncosurgery using hematological indices

Objective . To evaluate the informative value of the ratio of the absolute number of neutrophils to lymphocytes (NLR) and platelets to lymphocytes (PLR) in predicting cardiac complications during thoracic oncological operations. Materials and methods . Seventy-one patients aged 64 [60–71] years who underwent routine inpatient treatment in the thoracic surgery department were examined. Results. Concomitant cardiac diseases were diagnosed in 65 (91.6 %) patients. Cardiac complications in the form of a composite outcome were detected in 9 (12.7 %) patients, including 1 cardiac death. Both hematological indices were not predictors of CVD, both in assessing the composite outcome (NLR: OR — 1.23; 95 % CI — 0.19–3.46; p=0.07, PLR: OR — 0.85; 95 % CI — 0.89–2.02; p=0.68), and in relation to one case of cardiac mortality (p >0.05). Conclusion . The use of the hematological indices NLR and PLR cannot be recommended for predicting cardiac complications during thoracic oncological operations.
