Background Chronic obstructive pulmonary disease (COPD) is a frequent comorbidity in patients with heart failure (HF). We assessed the influence of COPD on circulating levels and prognostic value of 3 HF biomarkers: N-terminal pro-B-type natriuretic peptide (NT-proBNP), high-sensitivity troponin T (hs-TnT), and soluble suppression of tumorigenesis-2 (sST2). Methods Individual data from patients with chronic HF, known COPD status and NT-proBNP, hs-TnT, sST2 values (n=13328) were analysed. Results As compared to patients without COPD, those with COPD (n=2155, 16%) were older (age 71 years [64–77] vs. 66 [57–75]; p Conclusions Among patients with HF, those with COPD have higher circulating cardiac biomarkers. Patient classification based on COPD-specific cut-offs refines risk reclassification for all-cause and cardiovascular mortality and HF hospitalization and might be helpful for decision making and management.
