Research has shown that NT-proBNP levels are frequently elevated in COVID-19 patients and are strongly associated with prognosis.
Aims Extensive research regarding the association of troponin and prognosis in coronavirus disease 2019 (COVID-19) has been performed. However, data regarding natriuretic peptides are scarce. N-terminal pro B-type natriuretic peptide (NT-proBNP) reflects haemodynamic stress and has proven useful for risk stratification in heart failure (HF) and other conditions such as pulmonary embolism and pneumonia. We aimed to adequately characterize NT-proBNP concentrations using a large cohort of patients with COVID-19, and to investigate its association with prognosis. Methods and results Consecutive patients with confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and available NT-proBNP determinations, from March 1st to April 20th, 2020 who completed at least 1-month follow-up or died, were studied. Of 3080 screened patients, a total of 396 (mean age 71.8 +/- 14.6 years, 61.1% male) fulfilled all the selection criteria and were finally included, with a median follow-up of 53 (18-62) days. Of those, 192 (48.5%) presented NT-proBNP levels above the recommended cut-off for the identification of HF. However, only 47 fulfilled the clinical criteria for the diagnosis of HF. Patients with higher NT-proBNP during admission experienced more frequent bleeding, arrhythmias and HF decompensations. NT-proBNP was associated with mortality both in the whole study population and after excluding patients with HF. A multivariable Cox model confirmed that NT-proBNP was independently associated with mortality after adjusting for all relevant confounders (hazard ratio 1.28, 95% confidence interval 1.13-1.44, per logarithmic unit). Conclusion NT-proBNP is frequently elevated in COVID-19. It is strongly and independently associated with mortality after adjusting for relevant confounders, including chronic HF and acute HF. Therefore, its use may improve early prognostic stratification in this condition. [GRAPHICS] .
