PAH was diagnosed on the basis of echocardiograms demonstrating elevated right ventricle pressure beyond the postnatal age of 2 months. Logistic regression analysis was done for the multivariate assessment of the risk factors for PAH in preterm infants with moderate or severe BPD. &lt;i&gt;Results:&lt;\/i&gt; A total of 98 infants among 145 infants with BPD were divided into a PAH group (n = 25) or non-PAH group (n = 73), while the remaining 47 infants had mild BPD with no PAH. Among the study patients, survival rate of the PAH group was significantly lower than that of the non-PAH group. Infants with PAH had more severe cases of BPD and underwent longer durations of oxygen therapy, conventional or high-frequency ventilation, and hospitalization compared to those without PAH. Low 5-min Apgar scores (\u22646; relative risk (RR) 6.2; 95% confidence interval (CI) 1.4\u201328.0; p = 0.017) and oligohydramnios (RR 7.7; 95% CI 2.0\u201329.6; p = 0.030) were found to be significant risk factors for PAH according to multivariate analysis. &lt;i&gt;Conclusions:&lt;\/i&gt; The present study shows that oligohydramnios is a specific risk factor for PAH in preterm infants with moderate or severe BPD.<\/jats:p>","DOI":"10.1159\/000327891","type":"journal-article","created":{"date-parts":[[2011,7,26]],"date-time":"2011-07-26T06:39:45Z","timestamp":1311662385000},"page":"40-46","source":"Crossref","is-referenced-by-count":152,"title":["Risk Factors for Pulmonary Artery Hypertension in Preterm Infants with Moderate or Severe Bronchopulmonary Dysplasia"],"prefix":"10.1159","volume":"101","author":[{"given":"Do-Hyun","family":"Kim","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Han-Suk","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chang Won","family":"Choi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ee-Kyung","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Beyong Il","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jung-Hwan","family":"Choi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2011,7,26]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1056%2FNEJM196702162760701"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1016%2FS0046-8177%2898%2990280-5"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016%2FS1084-2756%2802%2900192-6"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1159%2F000209301"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1159%2F000111100"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1159%2F000263056"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1159%2F000121459"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1136%2Ffn.87.1.F15"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1136%2Ffn.70.2.F118"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1136%2Ffn.82.3.F243"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.ppedcard.2009.09.007"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1016%2FS0022-3476%2888%2980125-2"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1136%2Fadc.65.7.739"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1542%2Fpeds.2007-0971"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1542%2Fpir.9-7-219"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1016%2FS1084-2756%2802%2900191-4"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1164%2Frccm.200506-927OC"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1038%2Fsj.jp.7210580"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1016%2FS0095-5108%2803%2900076-9"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1007%2FBF02725633"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.1016%2FS0002-9378%2899%2970393-5"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.1016%2FS0002-9378%2800%2970345-0"},{"key":"ref23","doi-asserted-by":"publisher","DOI":"10.1542%2Fpeds.2007-1583"}],"container-title":["Neonatology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/327891","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/327891","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T19:16:52Z","timestamp":1745435812000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000327891"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011,7,26]]},"references-count":23,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2011,12,1]]},"published-print":{"date-parts":[[2011,12,21]]}},"URL":"https:\/\/doi.org\/10.1159\/000327891","archive":["Portico"],"relation":{},"ISSN":["1661-7800","1661-7819"],"issn-type":[{"value":"1661-7800","type":"print"},{"value":"1661-7819","type":"electronic"}],"subject":[],"published":{"date-parts":[[2011,7,26]]}}}
