Cardiological parameters predict mortality and cardiotoxicity in oncological patients

Abstract Aims Oncological patients suspected at risk for cardiotoxicity are recommended to undergo intensified cardiological surveillance. We investigated the value of cardiac biomarkers and patient‐related risk factors [age, cardiovascular risk factors (CVRFs), and cardiac function] for the prediction of all‐cause mortality (ACM) and the development of cardiotoxicity. Methods and results Between January 2016 and December 2020, patients with oncological diseases admitted to the Cardio‐Oncology Unit at the Heidelberg University Hospital were included. They were evaluated by medical history, physical examination, 12‐lead electrocardiogram, 2D echocardiography, and cardiac biomarkers [high‐sensitivity cardiac troponin T (hs‐cTnT) and N‐terminal pro‐brain natriuretic peptide (NT‐proBNP)]. The primary endpoint was defined as ACM and the secondary endpoint was defined as cardiotoxicity, as defined by the European Society of Cardiology. Of the 1971 patients enrolled, the primary endpoint was reached by 490 patients (25.7%) with a median of 363.5 [interquartile range (IQR) 121.8, 522.5] days after presentation. Hs‐cTnT of ≥ 7 ng/L [odds ratio (OR) 1.82, P
