Another possibility is that patients with COPD often demonstrate perturbations in the renin-angiotensin-aldosterone system with up-regulation of ACE and angiotensin II [9] that may be exacerbated during acute SARS-CoV-2 infection, leading to acute pulmonary hypertension and pulmonary edema. SARS-CoV-2 infection in the COPD population is associated with increased healthcare utilization: an analysis of Cleveland Clinic's COVID-19 Registry	./cache/cord-340420-ws3qesns.txt	./txt/cord-340420-ws3qesns.txt
