The aim of this study was to verify the value of RRI as a predictor of worsening renal function (WRF) in a group of chronic heart failure (CHF) outpatients. &lt;b&gt;&lt;i&gt;Methods:&lt;\/i&gt;&lt;\/b&gt; We enrolled 266 patients in stable clinical conditions and on conventional therapy. Peak systolic velocity and end diastolic velocity of a segmental renal artery were obtained by pulsed Doppler flow, and RRI was calculated. Creatinine serum levels were evaluated at baseline and at 1 year, and the changes were used to assess WRF occurrence. &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; During follow-up, 34 (13%) patients showed WRF. RRI was associated with WRF at univariate (OR: 1.13; 95% CI: 1.07-1.20) as well as at a forward stepwise multivariate logistic regression analysis (OR: 1.09; 95% CI: 1.03-1.16; p = 0.005) including the other univariate predictors. &lt;b&gt;&lt;i&gt;Conclusions:&lt;\/i&gt;&lt;\/b&gt; Quantification of arterial renal perfusion provides a new parameter that independently predicts the WRF in CHF outpatients. Its possible role in current clinical practice to better define the risk of cardiorenal syndrome progression is strengthened.<\/jats:p>","DOI":"10.1159\/000448405","type":"journal-article","created":{"date-parts":[[2016,9,20]],"date-time":"2016-09-20T21:01:43Z","timestamp":1474405303000},"page":"42-49","source":"Crossref","is-referenced-by-count":21,"title":["The Renal Arterial Resistance Index Predicts Worsening Renal Function in Chronic Heart Failure Patients"],"prefix":"10.1159","volume":"7","author":[{"given":"Massimo","family":"Iacoviello","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francesco","family":"Monitillo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marta","family":"Leone","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gaetano","family":"Citarelli","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Annalisa","family":"Doronzo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Valeria","family":"Antoncecchi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Agata","family":"Puzzovivo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Caterina","family":"Rizzo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria Silvia","family":"Lattarulo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francesco","family":"Massari","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pasquale","family":"Caldarola","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marco Matteo","family":"Ciccone","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2016,9,21]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2008.07.051"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehu320"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1161\/hy0202.103782"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1093\/ndt\/gfr116"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1161\/HYPERTENSIONAHA.112.196717"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2369-13-139"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1002\/ejhf.34"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1093\/eurjhf\/hfs105"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016\/j.echo.2010.05.010"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-150-9-200905050-00006"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1007\/s10741-011-9246-2"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1002\/cphy.c120012"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1159\/000366168"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijcard.2012.06.088"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijcha.2015.03.004"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1016\/j.cardfail.2007.04.008"}],"container-title":["Cardiorenal Medicine"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/448405","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/448405","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/448405","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T17:03:24Z","timestamp":1745427804000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000448405"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016,9,21]]},"references-count":16,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2016,11,23]]}},"URL":"https:\/\/doi.org\/10.1159\/000448405","archive":["Portico"],"relation":{},"ISSN":["1664-3828","1664-5502"],"issn-type":[{"value":"1664-3828","type":"print"},{"value":"1664-5502","type":"electronic"}],"subject":[],"published":{"date-parts":[[2016,9,21]]}}}
