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

Abstract Introduction The cardiac pacemaker is indicated for treating various types of bradyarrhythmia, providing lifelong cardiovascular benefits. Recent data showed that COVID‐19 has impacted procedure numbers and led to adverse long‐term outcomes in patients with cardiac pacemakers. However, the impact of COVID‐19 infection on the in‐hospital outcome of patients undergoing conventional pacemaker implantation remains unclear. Method Patients aged above 18 years who were hospitalized for conventional pacemaker implantation in the Nationwide In‐patient Sample (NIS) 2020 were identified using relevant ICD‐10 CM and PCS codes. Multivariable logistic and linear regression models were used to analyze pre‐specified outcomes, with the primary outcome being in‐patient mortality and secondary outcomes including system‐based and procedure‐related complications. Results Of 108 020 patients hospitalized for conventional pacemaker implantation, 0.71% (765 out of 108 020) had a concurrent diagnosis of COVID‐19 infection. Individuals with COVID‐19 infection exhibited a lower mean age (73.7 years vs. 75.9 years, p = .027) and a lower female proportion (39.87% vs. 47.60%, p = .062) than those without COVID‐19. In the multivariable logistic and linear regression models, adjusted for patient and hospital factors, COVID‐19 infection was associated with higher in‐hospital mortality (aOR 4.67; 95% CI 2.02 to 10.27, p

Introduction: The cardiac pacemaker is indicated for treating various types of bradyarrhythmia, providing lifelong cardiovascular benefits. Recent data showed that COVID‐19 has impacted procedure numbers and led to adverse long‐term outcomes in patients with cardiac pacemakers. However, the impact of COVID‐19 infection on the in‐hospital outcome of patients undergoing conventional pacemaker implantation remains unclear. Method: Patients aged above 18 years who were hospitalized for conventional pacemaker implantation in the Nationwide In‐patient Sample (NIS) 2020 were identified using relevant ICD‐10 CM and PCS codes. Multivariable logistic and linear regression models were used to analyze pre‐specified outcomes, with the primary outcome being in‐patient mortality and secondary outcomes including system‐based and procedure‐related complications. Results: Of 108 020 patients hospitalized for conventional pacemaker implantation, 0.71% (765 out of 108 020) had a concurrent diagnosis of COVID‐19 infection. Individuals with COVID‐19 infection exhibited a lower mean age (73.7 years vs. 75.9 years, p =.027) and a lower female proportion (39.87% vs. 47.60%, p =.062) than those without COVID‐19. In the multivariable logistic and linear regression models, adjusted for patient and hospital factors, COVID‐19 infection was associated with higher in‐hospital mortality (aOR 4.67; 95% CI 2.02 to 10.27, p <.001), extended length of stay (5.23 days vs. 1.04 days, p <.001), and linked with various in‐hospital complications, including sepsis, acute respiratory failure, post‐procedural pneumothorax, and venous thromboembolism. Conclusion: Our study suggests that COVID‐19 infection is attributed to higher in‐hospital mortality, extended hospital stays, and increased adverse in‐hospital outcomes in patients undergoing conventional pacemaker implantation.

Conclusion: Our study revealed that COVID‐19 is linked to higher in‐hospital mortality and increased adverse outcomes in AF patients hospitalized for HF. [ABSTRACT FROM AUTHOR]
