Association of atrial fibrillation with infectivity and severe complications of COVID‐19: A nationwide cohort study

Abstract

Infection is associated with the occurrence, recurrence, and progression of atrial fibrillation (AF), and is also closely related to poor prognosis. However, studies of the relationship between infectivity and severe complications of coronavirus infectious disease-19 (COVID-19) with a history of AF are limited.To estimate infectivity and severity of complications in COVID-19 patients with a history of AF, this study was done. From the Korean nationwide COVID-19 dataset, 212 678 participants with at least one severe acute respiratory syndrome coronavirus 2 (COVID-19) test were included between January 1 and June 4, 2020. AF was defined according to at least two outpatient hospital visits or one admission with an ICD-10 code of "I48" before the COVID-19 test. To investigate the association of AF with infectivity and severe complications of COVID-19, 1:4 ratio propensity score matching (PSM) was performed. Severe complications of COVID-19 were defined as a composite outcome of mechanical ventilation, intensive care unit admission, and death within 2 months after COVID-19 diagnosis. Among 212 678 participants who underwent the COVID-19 test, there were 7713 COVID-19 positive patients. After PSM,

Prognostic Factors Associated with Acute Heart Failure in Patients Admitted for COVID-19: Analysis of the SEMI-COVID-19 Registry

“…The fact that atrial fibrillation appears as a predictor for the development of HF is consistent with findings found in other studies in which patients with atrial fibrillation had higher rates of mortality and complications [24]. In another study, it was observed that 5% of patients hospitalized for COVID-19 developed a first episode of atrial fibrillation and had higher rates of hypertension and HF than those who did not develop atrial fibrillation [25].…”

Association of Cerebral Venous Thrombosis with mRNA COVID-19 Vaccines: A Disproportionality Analysis of the World Health Organization Pharmacovigilance Database

“…Coronavirus disease 2019 (COVID-19) is spreading rapidly [ 1 , 2 , 3 , 4 , 5 ]. Herd immunity is important for the prevention and suppression of the spread of COVID-19, and vaccination is an essential requirement for herd immunity [ 6 ].…”

Associations of Guillain‐Barré syndrome with coronavirus disease 2019 vaccination: Disproportionality analysis using the World Health Organization pharmacovigilance database

“…Severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2), which causes coronavirus disease 2019 (COVID‐19), is still spreading around the world. Although the severity decreased after the omicron variation became the main type, people with comorbidities still require respiratory care or may even die 1‐4 . Accordingly, achieving herd immunity is important to limit COVID‐19 cases as much as possible, and vaccination is one available strategy to attain herd immunity 5 .…”
