COVID‐19 And Older Adults: What We Know

Studies have shown SARS‐CoV‐2, a novel virus that causes COVID‐19 infection, causes worse outcomes and a higher mortality rate in older adults and those with comorbidities such as hypertension, cardiovascular disease, diabetes, chronic respiratory disease, and chronic kidney disease.

Clinical Implications of SARS-Cov2 Interaction with Renin Angiotensin System

This report concludes that in patients with cardiovascular disease and SARS-CoV2, the use of ACE inhibitors, ARBs [angiotensin receptor blockers], or MRAs [mineralocorticoid-receptor antagonists] may be favorable as a method to endogenously upregulate ACE2 as a compensatory mechanism that provides anti-inflammatory, antifibrotic, and antithrombotic support as well as reduction in progression of vascular/cardiac remodeling and heart failure.

Severe acute respiratory syndrome coronavirus 2 infection, angiotensin-converting enzyme 2 and treatment with angiotensin-converting enzyme inhibitors or angiotensin II type 1 receptor blockers

Data from the China epidemic and the COVID-19 deaths show that most of those patients were old and commonly affected by CVD. This article discusses the role of ACE2 in the CV system and in acute respiratory syndromes. There is no evidence that these drugs can improve or worsen SARS-CoV-2 lung invasion and COVID-19 course.

Inhibitors of the Renin–Angiotensin–Aldosterone System and Covid-19

This editorial comments on three studies published in the same edition and concludes that patients should not discontinue ACE inhibitor or ARB therapy out of a concern that they are at increased risk for infection, severe illness, or death during the Covid-19 pandemic. Each of these studies has weaknesses inherent in observational data, but it is reassuring that they deliver a consistent message that the continued use of ACE inhibitors and ARBs is unlikely to be harmful in patients with COVID-19.
