Insights
Physicians should continue renin-angiotensin system (RAS) inhibitors, such as ACE-inhibitors and ARBs, for patients with cardiovascular disease and COVID-19. Expert guidelines advise against altering these essential treatments based on clinical status.
Area of Science:
- Cardiology
- Infectious Diseases
- Pharmacology
Background:
- COVID-19, caused by SARS-CoV-2, poses a global health challenge.
- Hypertension and cardiovascular disease increase COVID-19 mortality risk.
- SARS-CoV-2 utilizes ACE2 for cell entry, raising concerns about RAS modulators.
Purpose of the Study:
- To review literature on the association between RAS inhibitors and severe COVID-19.
- To determine the appropriateness of continuing ACE-inhibitors and ARBs in active COVID-19 cases.
Main Methods:
- Literature review of studies on RAS inhibitors (ACE-inhibitors, ARBs) and COVID-19 severity.
- Analysis of recommendations regarding medication continuation in infected patients.
Main Results:
- Concerns exist regarding RAS antagonists potentially increasing COVID-19 severity due to ACE2 upregulation.
- Evidence synthesis to inform clinical decision-making.
Conclusions:
- Major cardiology societies recommend against initiating or withdrawing RAS inhibitors for COVID-19 patients with cardiovascular disease.
- Treatment decisions for ACE-inhibitors/ARBs should be individualized based on patient presentation and hemodynamics.
Introduction:
The novel coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory system-coronavirus-2 (SARS-CoV-2), is an important medical problem worldwide. Increased risk of mortality has been reported in patients with cardiovascular disease, such as hypertension (HTN). SARS-CoV-2 invades the pulmonary alveolar epithelial cells by binding to the surface receptor, angiotensin-converting enzyme 2 (ACE2). Renin-angiotensin system (RAS) modulators can increase levels of ACE2. Thus, concerns have been raised regarding an increased risk of severe COVID-19 infection in patients receiving RAS antagonists.
Areas Covered:
We reviewed current literature about the potential association between the utilization of RAS inhibitors, namely angiotensin-converting enzyme inhibitors (ACE-inhibitors) and angiotensin-receptor blockers (ARBs) and likelihood of developing severe COVID-19 infection and whether or not continuation of these medications is appropriate in patients with active disease.
Expert Opinion:
The joint statement from the American College of Cardiology (ACC), American Heart Association (AHA), European Society of Cardiology (ESC) and Heart Failure Society of America (HFSA), strongly recommends that physicians should not initiate or withdraw their usual RAS-related treatments (ACE-inhibitor/ARB) to COVID-19 infected patients with cardiovascular disease. The decision should be made based upon each patient's clinical presentation and hemodynamic status.
