Impact of COVID-19 infection on the in-hospital outcome of patients hospitalized for heart failure with comorbid atrial fibrillation: Insight from the National Inpatient Sample (NIS) database 2020.

ABSTRACT:

Introduction

Atrial fibrillation (AF) and heart failure (HF) commonly coexist, resulting in adverse health and economic consequences such as declining ventricular function, heightened mortality, and reduced quality of life. However, limited information exists on the impact of COVID-19 on AF patients that hospitalized for HF.

Methods

We analyzed the 2020 U.S. National Inpatient Sample to investigate the effects of COVID-19 on AF patients that primarily hospitalized for HF. Participants aged 18 and above were identified using relevant ICD-10 CM codes. Adjusted odds ratios for outcomes were calculated through multivariable logistic regression. The primary outcome was inpatient mortality, with secondary outcomes including system-based complications.

Results

We identified 322,090 patients with primary discharge diagnosis of HF with comorbid AF. Among them, 0.73% (2355/322,090) also had a concurrent diagnosis of COVID-19. In a survey multivariable logistic and linear regression model adjusting for patient and hospital factors, COVID-19 infection was associated with higher in-hospital mortality (aOR 3.17; 95% CI 2.25, 4.47, p < 0.001), prolonged length of stay (β _LOS 2.82; 95% CI 1.71, 3.93, p < 0.001), acute myocarditis (aOR 6.64; 95% CI 1.45, 30.45, p 0.015), acute kidney injury (AKI) (aOR 1.48; 95% CI 1.21, 1.82, p < 0.001), acute respiratory failure (aOR 1.24; 95% CI 1.01, 1.52, p 0.045), and mechanical ventilation (aOR 2.00; 95% CI 1.28, 3.13, p 0.002).

Conclusion

Our study revealed that COVID-19 is linked to higher in-hospital mortality and increased adverse outcomes in AF patients hospitalized for HF.
