Aim: The aim of this study is to evaluate cardiac complications (CC) and risk factors associated with these complications in patients after lung resection. Methods: Cardiac complications were observed in 136 (11.4%) of 1186 patients who underwent lung resection in a single center between 2017 and 2020. 136 patients who developed complications in the same period and 215 patients who had consecutive operations and did not develop complications were included in the study Results: 287 (81.7%) of the patients were male and the mean age was 58.9 years. There is a statistically significant relationship between cardiac complications after lung resection with geriatric age, male gender, presence of hypertension (HT), presence of lung cancer, neoadjuvant therapy, high SOFA score, chronic obstructive pulmonary disease (COPD), and cerebrovascular accident (CVA). In addition, CVA, EF<60%, neoadjuvant therapy, pneumonectomy, high Sequential Organ Failure Assessment score (SOFA) and intraoperative blood transfusion were found to be independent risk factors for the development of complications. Among the intraoperative factors, pneumonectomy (p<0.001), thoracotomy (p=0.002), intraoperative blood product use (p<0.001) and inotropic use (p<0.001) were correlated with CC. In multiple logistic regression analysis, preoperative thyroid disease (p=0.04), CVA (p=0.001), neoadjuvant therapy (p=0.002), EF<60% (p=0.01), pneumonectomy (p=0.003), intraoperative blood transfusion (p<0.0001) and high SOFA score (p<0.0001) emerged as independent risk factors affecting the development of cardiac complications. Conclusions: There is significant relationship between cardiac complications after lung resection with geriatric age, male sex, HT, lung cancer presence, neoadjuvant therapy, high SOFA score, COPD, CVA presence. In addition, CVA, EF< 60%, neoadjuvant therapy, pneumonectomy and high SOFA score and intraoperative blood transfusion were identified as independent risk factors in the development of complications.
