The two-dimensional transthoracic echocardiography was performed according to the Guidelines of the American Society of Echocardiography and the European Association of Cardiovascular Imaging.Results:\u00a0A total of 103 men (47.5%) (mean age: 39.5\u00b110,8) and 114 women (52.5%) (mean age: 43.0\u00b112,5 years) were included. Compared to men, women were older (p=0.025) and had a significantly smaller body surface area (BSA) (p&lt;0.001). Left ventricular wall thickness, left ventricular end-diastolic dimension and volume (LVEDV), left ventricular mass (LVM) and LVM indexed to BSA (LVMi) were significantly lower in women (p&lt;0.005). LVEDD indexed to BSA and left ventricular ejection fraction (LVEF) were significantly higher in women than in men (p=0.007), (p=0.01), respectively. Mitral annular plane systolic excursion, LVEF by strain, and global longitudinal strain showed no gender differences. Posterior wall thickness showed a statistically significant increase in the older groups (p=0.043). The VST, relative wall thickness, LVM, and LVMi showed no significant differences between age categories. In turn, the shortening fraction and the ejection fraction increase with age.Conclusion:\u00a0For a more sensitive morphological and functional assessment of the left ventricle, it is necessary to take into account the gender and age of the individual.<\/jats:p>","DOI":"10.21542\/gcsp.2022.2","type":"journal-article","created":{"date-parts":[[2022,8,9]],"date-time":"2022-08-09T13:25:42Z","timestamp":1660051542000},"source":"Crossref","is-referenced-by-count":2,"title":["Global longitudinal strain and echocardiographic parameters of left ventricular geometry and systolic function in healthy adult Angolans: Effect of age and gender"],"prefix":"10.21542","volume":"2022","author":[{"given":"Humberto","family":"Morais","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ana","family":"Feij\u00e3o","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Savarino de Vict\u00f3ria","family":"Pereira","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"8990","published-online":{"date-parts":[[2022,6,7]]},"container-title":["Global Cardiology Science and Practice"],"original-title":[],"link":[{"URL":"https:\/\/www.globalcardiologyscienceandpractice.com\/index.php\/gcsp\/article\/download\/558\/pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.globalcardiologyscienceandpractice.com\/index.php\/gcsp\/article\/download\/558\/pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,16]],"date-time":"2023-09-16T22:11:21Z","timestamp":1694902281000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.globalcardiologyscienceandpractice.com\/index.php\/gcsp\/article\/view\/558"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,6,7]]},"references-count":0,"journal-issue":{"issue":"1-2","published-online":{"date-parts":[[2022,5,23]]}},"URL":"https:\/\/doi.org\/10.21542\/gcsp.2022.2","relation":{},"ISSN":["2305-7823"],"issn-type":[{"value":"2305-7823","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,6,7]]}}}
