The control group included 40 children born full-term, selected from one general practice in the district. Echocardiography and 24-hour ambulatory blood pressure measurements (ABPM) were performed. The primary outcome variable was the presence of cardiac complications such as left ventricular hypertrophy (LVH), diastolic dysfunction or systolic dysfunction. &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; LVH was diagnosed in 4\/81 ELBW children and 2\/40 control children (p = 1.0). Concentric remodeling was detected in 8 (10%) subjects from the ELBW group and in 2 (5%) from the control group (p = 0.49). There were no patients with diastolic or systolic dysfunction in either group. After having expressed the results of M-mode echocardiography as z-scores for body surface area (BSA), statistically significant differences were observed for right-ventricle dimension in diastole (-1.49 \u00b1 1.25 vs. -0.31 \u00b1 0.91; p &lt; 0.001), LV inner dimension in diastole (-0.53 \u00b1 1.26 vs. 0.13 \u00b1 0.94; p = 0.01) and left atrium (-0.93 \u00b1 1.07 vs. -0.15 \u00b1 1.02; p &lt; 0.01). Heart rate (HR) was significantly faster in ELBW children (92.9 \u00b1 8.4 vs. 86.7 \u00b1 7.4 bpm; p = 0.01 adjusted for BSA) and they also had significantly higher night-time blood pressure [mean (z-score): 1.15 vs. 0.2; p = 0.02] without nocturnal dipping (night-time dipping &lt;10%: 13 (16.7%) vs. 2 (5.2%), p = 0.13). &lt;b&gt;&lt;i&gt;Conclusions:&lt;\/i&gt;&lt;\/b&gt; No differences were found between the groups in the occurrence of cardiac complications. Ex-preterm ELBW children at age 6 may have a faster HR, smaller cardiac dimensions on echocardiography and higher nocturnal blood pressure. The clinical relevance of these findings is unknown.<\/jats:p>","DOI":"10.1159\/000348251","type":"journal-article","created":{"date-parts":[[2013,3,21]],"date-time":"2013-03-21T13:44:48Z","timestamp":1363873488000},"page":"287-292","source":"Crossref","is-referenced-by-count":7,"title":["From a Regional Cohort of Extremely Low Birth Weight Infants: Cardiac Function at the Age of 7 Years"],"prefix":"10.1159","volume":"103","author":[{"given":"Przemko","family":"Kwinta","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mateusz","family":"Jag\u0142a","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrzej","family":"Grudzie\u0144","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ma\u0142gorzata","family":"Klimek","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Magdalena","family":"Zasada","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jacek Jozef","family":"Pietrzyk","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2013,3,21]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.39555.670718.BE"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1097\/01.AOG.0000284447.43442.55"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1136\/heart.83.6.667"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.67.3.579"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.55.4.613"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.107.741157"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1016\/0735-1097(92)90385-Z"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9149(99)80200-8"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016\/j.echo.2009.03.003"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1016\/0735-1097(92)90617-V"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(98)00379-9"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.0000154900.76284.F6"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1097\/00004872-200210000-00019"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpeds.2007.04.030"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1111\/j.1651-2227.2008.00890.x"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1515\/jpme.1990.18.6.459"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1046\/j.1469-7580.1997.19110107.x"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1006\/jmcc.1996.0163"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1203\/PDR.0b013e3181a283a0"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1159\/000330804"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.1155\/2012\/537936"}],"container-title":["Neonatology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/348251","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/348251","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T18:54:40Z","timestamp":1745434480000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000348251"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013]]},"references-count":21,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2013,5,1]]},"published-print":{"date-parts":[[2013,5,31]]}},"URL":"https:\/\/doi.org\/10.1159\/000348251","archive":["Portico"],"relation":{},"ISSN":["1661-7800","1661-7819"],"issn-type":[{"type":"print","value":"1661-7800"},{"type":"electronic","value":"1661-7819"}],"subject":[],"published":{"date-parts":[[2013]]}}}
