Understanding Heart Inflammation and COVID-19 for Athletes and Others

Myocarditis can affect anyone, even healthy young adults and children. Adenoviruses and enteroviruses, such as Coxsackieviruses (hand, foot and mouth disease), are among the most common culprits. But SARS-CoV-2 (COVID-19) may cause heart inflammation, too. And, as we are learning, COVID-19-related inflammation can have a long-term impact on heart health.

Critical Transition Theory Shows Flickering in Heart Before Atrial Fibrillation

Atrial fibrillation ranks among the most common heart conditions, and episodes are difficult to predict. Researchers have proposed a way to define cardiac state and have studied the dynamics before the cardiac rhythm changes from normal sinus to AF rhythm and vice versa. The work, appearing in Chaos and based on critical transition theory, looks to provide an early warning for those with paroxysmal atrial fibrillation with potential implications for future wearable devices.
