Risk analysis of cardiac disease mortality within 3 months in patients with lung cancer after surgery: A real-world cohort study.

ObjectiveTo determine the 3-month heart disease-related mortality rate among patients with lung cancer who have undergone lobectomy and identify the common risk factors for mortality to provide a basis for clinical risk assessment and intervention strategies.MethodsWe conducted a retrospective cohort study using the Surveillance, Epidemiology, and End Results Program database (2010-2015), including 35,094 patients with stage I-III lung cancer who underwent surgery. Logistic regression analyzed mortality at 3, 7, and 11 months, focusing on non-cancer causes, particularly heart diseases.ResultsAmong the 35,094 patients, 3.24% (1138) died within 3 months, with heart disease accounting for 8.96% (102) of the deaths, a significantly higher percentage than that at 4-7 months (p = 0.017). Logistic regression analysis showed that several factors, including sex, age, postoperative radiotherapy, and postoperative systematic treatment were independent factors contributing to mortality owing to heart diseases within 3 months of surgery.ConclusionsIn this study, we analyzed the causes of early death in patients who had undergone lung cancer surgery and determined the independent risk factors associated with 3-month mortality due to heart disease in these patients.
