Sistema renina-angiotensina-aldosterona y COVID19. Implicaciones clínicas

The pandemic caused by the rapid spread of the SARS-CoV-2 virus has produced the greatest health crisis of modern times. The close relationship between the virus and angiotensin-II converting enzyme has provoked a torrent of speculation about the possible role of the renin-angiotensin-aldosterone system (RAAS) in mediating infection. The subsequent alarm has raised questions about the use of RAAS inhibitors, such as angiotensin-converting enzyme inhibitors and angiotensin-II receptor blockers. The result has been the publication of several studies that have failed to find an association between the use of RAAS inhibitors and greater susceptibility to infección or a worse clínical outlook. This review considers the most significant aspects of the interaction between SARS-CoV-2 and the RAAS and the clínical implications of using RAAS inhibitors during the pandemic.
