All these cardiovascular morbidities are widespread in the population and often coexist, thus identifying a common patient phenotype, characterized by a hyper-activation of the \u201cclassic\u201d renin-angiotensin system (RAS) and mediated by the binding of angiotensin II (Ang II) to the type 1-receptor. At the same time, the RAS imbalance was proved to be crucial in the genesis of lung injury after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, where angiotensin-converting-enzyme-2 (ACE2) is not only the receptor for SARS-CoV-2, but its down-regulation through internalization and shedding, caused by the virus binding, leads to a further dysregulation of RAS by reducing angiotensin 1-7 (Ang 1-7) production. This focused narrative review will discuss the main available evidence on the role played by cardiovascular and metabolic conditions in severe COVID-19, providing a possible pathophysiological link based on the disequilibrium between the two opposite arms of RAS.<\/jats:p>","DOI":"10.3390\/jcm10245883","type":"journal-article","created":{"date-parts":[[2021,12,15]],"date-time":"2021-12-15T09:02:19Z","timestamp":1639558939000},"page":"5883","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["The Identikit of Patient at Risk for Severe COVID-19 and Death: The Dysregulation of Renin-Angiotensin System as the Common Theme"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5159-0181","authenticated-orcid":false,"given":"Riccardo","family":"Sarzani","sequence":"first","affiliation":[{"name":"Internal Medicine and Geriatrics, IRCCS INRCA, Via della Montagnola 81, 60127 Ancona, Italy"},{"name":"Department of Clinical and Molecular Sciences, University \u201cPolitecnica delle Marche\u201d, Via Tronto 10\/a, 60126 Ancona, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Massimiliano","family":"Allevi","sequence":"additional","affiliation":[{"name":"Internal Medicine and Geriatrics, IRCCS INRCA, Via della Montagnola 81, 60127 Ancona, Italy"},{"name":"Department of Clinical and Molecular Sciences, University \u201cPolitecnica delle Marche\u201d, Via Tronto 10\/a, 60126 Ancona, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Federico","family":"Giulietti","sequence":"additional","affiliation":[{"name":"Internal Medicine and Geriatrics, IRCCS INRCA, Via della Montagnola 81, 60127 Ancona, Italy"},{"name":"Department of Clinical and Molecular Sciences, University \u201cPolitecnica delle Marche\u201d, Via Tronto 10\/a, 60126 Ancona, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chiara","family":"Di Pentima","sequence":"additional","affiliation":[{"name":"Internal Medicine and Geriatrics, IRCCS INRCA, Via della Montagnola 81, 60127 Ancona, Italy"},{"name":"Department of Clinical and Molecular Sciences, University \u201cPolitecnica delle Marche\u201d, Via Tronto 10\/a, 60126 Ancona, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Serena","family":"Re","sequence":"additional","affiliation":[{"name":"Internal Medicine and Geriatrics, IRCCS INRCA, Via della Montagnola 81, 60127 Ancona, Italy"},{"name":"Department of Clinical and Molecular Sciences, University \u201cPolitecnica delle Marche\u201d, Via Tronto 10\/a, 60126 Ancona, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Piero","family":"Giordano","sequence":"additional","affiliation":[{"name":"Internal Medicine and Geriatrics, IRCCS INRCA, Via della Montagnola 81, 60127 Ancona, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1846-7819","authenticated-orcid":false,"given":"Francesco","family":"Spannella","sequence":"additional","affiliation":[{"name":"Internal Medicine and Geriatrics, IRCCS INRCA, Via della Montagnola 81, 60127 Ancona, Italy"},{"name":"Department of Clinical and Molecular Sciences, University \u201cPolitecnica delle Marche\u201d, Via Tronto 10\/a, 60126 Ancona, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,12,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"565","DOI":"10.1016\/S0140-6736(20)30251-8","article-title":"Genomic characterisation and epidemiology of 2019 novel coronavirus: Implications for virus origins and receptor binding","volume":"395","author":"Lu","year":"2020","journal-title":"Lancet"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1017","DOI":"10.1177\/2047487320924501","article-title":"Cardiovascular disease and COVID-19: Les liaisons dangereuses","volume":"27","author":"Barison","year":"2020","journal-title":"Eur.
