Abstract

Aims: We examined the value of N-terminal pro-B-type natriuretic peptide (NT-proBNP) in patients admitted for coronavirus disease 2019 (COVID-19) without prior history of heart failure (HF) or cardiomyopathy.

Methods and results: Retrospective cohort of consecutive adults (N = 679; median age 59 years; 38.7% women; 87.5% White; 7.1% Black; 5.4% Asian; 34.3% Hispanic) admitted with documented COVID-19 in an academic centre in Long Island, NY. Admission NT-proBNP was categorized using the European Society of Cardiology Heart Failure Association age-specific criteria for acute presentations. We examined (i) mortality and the composite of death or mechanical ventilation and (ii) out-of-hospital, intensive care unit (ICU)-free, and ventilator-free days at 28 days. Estimates were adjusted for confounders using a lasso selection process. Using age-specific criteria, 417 patients (61.4%) had low, 141 (20.8%) borderline, and 121 (17.8%) high NT-proBNP. Mortality was 5.8%, 20.6%, and 36.4% for patients with low, borderline, and high NT-proBNP, respectively. In lasso-adjusted models, high NT-proBNP was associated with higher mortality [hazard ratio (HR) 2.15; 95% confidence interval (CI) 1.06-4.39; P = 0.034] and composite endpoint rates (HR 1.66; 95%CI 1.04-2.66; P = 0.035). Patients with high NT-proBNP had 32%, 33%, and 33% fewer out-of-hospital, ICU-free, and ventilator-free days compared with low NT-proBNP counterparts. Results were consistent across age, sex, and race, and regardless of coronary artery disease or hypertension, except for stronger mortality signal with high NT-proBNP in women.

Conclusions: In patients with COVID-19 and no HF history, high admission NT-proBNP is associated with higher mortality and healthcare resources utilization. Preventive strategies may be required for these patients.
