O strain longitudinal global (SLG) fornece sensibilidade superior para avaliar a fun\u00e7\u00e3o sist\u00f3lica em compara\u00e7\u00e3o aos par\u00e2metros tradicionais, aumentando a precis\u00e3o diagn\u00f3stica em v\u00e1rias condi\u00e7\u00f5es card\u00edacas. No entanto, faltam valores de refer\u00eancia para SLG em diversas popula\u00e7\u00f5es.  Objetivos  Estabelecer valores de refer\u00eancia para SLGVE e strain longitudinal da parede livre do ventr\u00edculo direito (SLPLVD) em uma popula\u00e7\u00e3o multi\u00e9tnica brasileira sem fatores de risco cardiovascular ou doen\u00e7a. Tamb\u00e9m exploramos como fatores cl\u00ednicos e ecocardiogr\u00e1ficos influenciam a distribui\u00e7\u00e3o do SLG, abordando uma lacuna nas diretrizes globais que geralmente dependem de dados de popula\u00e7\u00f5es homog\u00eaneas ou geograficamente distantes.  M\u00e9todos  Inclu\u00edmos 1.048 participantes da coorte ELSA-Brasil que foram submetidos \u00e0 ecocardiografia com an\u00e1lise do SLG. Uma subamostra saud\u00e1vel (n = 527) foi definida pela exclus\u00e3o de indiv\u00edduos com doen\u00e7a cardiovascular ou renal, hipertens\u00e3o ou diabetes para estabelecer intervalos de refer\u00eancia do SLG. A preval\u00eancia de SLG anormal foi avaliada, e foram identificados fatores associados \u00e0 redu\u00e7\u00e3o de SLGVE e SLPLVD. A signific\u00e2ncia estat\u00edstica foi definida como p &lt; 0,05.  Resultados  Na subamostra saud\u00e1vel (idade m\u00e9dia de 50,2 anos, 59% do sexo feminino), a m\u00e9dia de SLGVE foi de 19,0% (intervalo de confian\u00e7a de 95%: 14,3 a 23,8), e a m\u00e9dia de SLPLVD foi de 28,3% (intervalo de confian\u00e7a de 95%: 22,3 a 34,3). As mulheres exibiram valores mais altos de SLGVE e SLPLVD do que os homens, sem diferen\u00e7as significativas relacionadas \u00e0 idade. Valores anormais de SLGVE e SLPLVD foram observados em 3,8% e 1,6% dos participantes, respectivamente. O SLGVE mais baixo foi associado \u00e0 obesidade, hipertens\u00e3o e diabetes; o SLPLVD reduzido foi correlacionado com maior \u00edndice de massa corporal e massa do VE.  Conclus\u00f5es  Propomos valores de refer\u00eancia para SLGVE e SLPLVD em uma grande coorte brasileira, destacando associa\u00e7\u00f5es com comorbidades cardiovasculares e estrutura ventricular.<\/jats:p>","DOI":"10.36660\/abc.20240634","type":"journal-article","created":{"date-parts":[[2025,6,17]],"date-time":"2025-06-17T13:51:32Z","timestamp":1750168292000},"source":"Crossref","is-referenced-by-count":0,"title":["Strain Ventricular em uma Popula\u00e7\u00e3o Adulta Brasileira do Estudo ELSA-Brasil: Valores de Refer\u00eancia e seus Determinantes"],"prefix":"10.36660","volume":"122","author":[{"given":"Eduardo Gatti","family":"Pianca","sequence":"first","affiliation":[{"name":"Universidade Federal do Rio Grande do Sul,  Brasil;
