Incidence and Clinical Outcomes of New-Onset Atrial Fibrillation in Critically lll Patients with COVID-19: A Multicenter Cohort Study - New-Onset Atrial Fibrillation and COVID-19.

Atrial fibrillation (Afib) can contribute to a significant increase in mortality and morbidity in critically ill patients. Thus, our study aims to investigate the incidence and clinical outcomes associated with the new-onset Afib in critically ill patients with COVID-19. A multicenter, retrospective cohort study includes critically ill adult patients with COVID-19 admitted to the intensive care units (ICUs) from March, 2020 to July, 2021. Patients were categorized into two groups (new-onset Afib vs control). The primary outcome was the in-hospital mortality. Other outcomes were secondary, such as mechanical ventilation (MV) duration, 30-day mortality, ICU length of stay (LOS), hospital LOS, and complications during stay. After propensity score matching (3:1 ratio), 400 patients were included in the final analysis. Patients who developed new-onset Afib had higher odds of in-hospital mortality (OR 2.76; 95% CI: 1.49-5.11, P = .001). However, there was no significant differences in the 30-day mortality. The MV duration, ICU LOS, and hospital LOS were longer in patients who developed new-onset Afib (beta coefficient 0.52; 95% CI: 0.28-0.77; P < .0001,beta coefficient 0.29; 95% CI: 0.12-0.46; P < .001, and beta coefficient 0.35; 95% CI: 0.18-0.52; P < .0001; respectively). Moreover, the control group had significantly lower odds of major bleeding, liver injury, and respiratory failure that required MV. New-onset Afib is a common complication among critically ill patients with COVID-19 that might be associated with poor clinical outcomes; further studies are needed to confirm these findings.

Coronavirus Disease 2019 Associated Acute Myocardial Infarction and Atrial Fibrillation: A Case Report.

In the last two years since the inception of the Coronavirus pandemic, there have been a myriad of reports and studies related to Coronavirus disease 2019 (COVID-19). We present a unique case of COVID-19 associated with both acute myocardial infarction and new-onset atrial fibrillation (AFIB) in an elderly lady which is the first reported case to the best of our knowledge. The patient was symptomatic with acute COVID-19 and developed a type 2 myocardial infarction with new-onset AFIB. The patient also developed sepsis which may have contributed to the development of AFIB.
