Evolutionary and Prognostic Particularities in Pacients with COPD, Chronic Cor Pulmonale and COVID-19

COPD is a chronic disease of the respiratory airways due to the partially reversible obstruction of the airflow caused by an abnormal inflammatory response to toxic substances, most often to cigarette smoke⁽¹⁾. COVID-19 is a mild to severe respiratory disease caused by a coronavirus from the Betacoronavirusgenus⁽²⁾. Patients with COPD have a major risk of COVID-19 infection. Treating patients with COPD, chronic cor pulmonale and COVID-19 is a current challenge.
