Study shows a protective association between anticoagulants and COVID-19

Analysis of data on people with atrial fibrillation using anticoagulants and warfarin found them both to lower the risk of testing positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and severe disease. COVID-19 disease may predispose some people to diseases related to blood clots because of disease severity or severe inflammatory response. Anticoagulants can

Atrial fibrillation: Diagnosis and testing

A doctor may perform one or more tests to diagnose atrial fibrillation (A-fib). The doctor will look for signs of A-fib as well as any underlying conditions that might be causing arrhythmia and possible complications. Sometimes a doctor will refer someone to a cardiologist, who is a specialist in heart disease. In this article, we

Inflammatory signals in heart muscle cells linked to atrial fibrillation

Interfering with inflammatory signals produced by heart muscle cells might someday provide novel therapeutic strategies for atrial fibrillation, according to an international team of researchers who have published their findings in the journal Circulation. “Atrial fibrillation is the most common heart arrhythmia, and it is particularly observed in the elderly human population, which is growing
