Materials and Methods: A total of 64 children were included in the study, consisting of 32 children aged 7 to 11 years with a history of preterm birth and 32 age- and gender-matched term birth controls. Results: While no significant differences were detected between the preterm and term birth groups regarding age, height, and body weight, echocardiographic data revealed higher values of mitral E, mitral A, and tricuspid A by pulse wave Doppler, as well as septal E by tissue Doppler, in the preterm group compared to the term birth group (p &lt; 0.05). Additionally, the left ventricular global longitudinal peak strain, right ventricular free wall and right ventricular 4-chamber strain, IVRT, MPI, MAPSE, and LVESV values were lower in the preterm group than in the term birth group (p &lt; 0.05). No significant differences were detected in circumferential strain measurements. Right ventricular strain measurements were significantly lower in the preterm group (p = 0.001). Conclusions: While conventional echocardiographic examinations did not reveal obvious pathological findings in school-age children with a history of preterm birth, further echocardiographic assessments demonstrated differences compared to term birth controls, particularly in diastolic functions and right and left ventricular longitudinal strain measurements.<\/jats:p>","DOI":"10.3390\/medicina61040573","type":"journal-article","created":{"date-parts":[[2025,3,24]],"date-time":"2025-03-24T13:48:20Z","timestamp":1742824100000},"page":"573","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Impact of Preterm Birth on Long-Term Cardiac Function: A Comprehensive Echocardiographic Study in School-Aged Children"],"prefix":"10.3390","volume":"61","author":[{"given":"Nidai","family":"Dalokay","sequence":"first","affiliation":[{"name":"Department of Pediatrics, Faculty of Medicine, Eski\u015fehir Osmangazi University, Eskisehir 26040, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ayse","family":"Sulu","sequence":"additional","affiliation":[{"name":"Department of Pediatric Cardiology, Faculty of Medicine, Eskisehir Osmangazi University, Eskisehir 26040, Turkey"},{"name":"Department of Pediatric Cardiology, Faculty of Medicine, Gaziantep University, Gaziantep 27310, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pelin","family":"Kosger","sequence":"additional","affiliation":[{"name":"Department of Pediatric Cardiology, Faculty of Medicine, Eskisehir Osmangazi University, Eskisehir 26040, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tugba Barsan","family":"Kaya","sequence":"additional","affiliation":[{"name":"Department of Neonatology, Faculty of Medicine, Eski\u015fehir Osmangazi University, Eskisehir 26040, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Birsen","family":"Ucar","sequence":"additional","affiliation":[{"name":"Department of Pediatric Cardiology, Faculty of Medicine, Eskisehir Osmangazi University, Eskisehir 26040, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,3,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1261","DOI":"10.1016\/S0140-6736(23)00878-4","article-title":"National, regional, and global estimates of preterm birth in 2020, with trends from 2010: A systematic analysis","volume":"402","author":"Ohuma","year":"2023","journal-title":"Lancet"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"253","DOI":"10.1007\/s10654-014-9892-5","article-title":"Cerebrovascular and ischemic heart disease in young adults born preterm: A population-based Swedish cohort study","volume":"29","author":"Ueda","year":"2014","journal-title":"Eur.
