Resumo: BACKGROUND: Left atrial volume index (LAVI) increase has been associated to left ventricle (LV) diastolic dysfunction (DD), a marker of cardiovascular events (atrial fibrillation, stroke, heart failure, death). OBJECTIVE: To evaluate the relationship between LAVI and diferente grades od DD in Brazilian patients submitted to echocardiogram, studying LAVI increase determinants in this sample. METHODS: We have selected 500 outpatients submitted to echocardiography, after excluding arrhythmia, valvar or congenital cardiopathy, permanent pacemaker or inadequate ecocardiographic window. LAVI was obtained according to Simpson's method. DD was classified according to current guidelines. The clinical and echocardiographic variables were submitted to linear regression multivariate analysis. RESULTS: Mean age was 52 ± 15 years old, 53% were male, 55% had arterial hypertension, 9% had coronary artery disease, 8% were diabetic, 24% were obese, 47% had LV hypertrophy. The mean ejection fraction of the left ventricle was 69.6 ± 7,2%. The prevalence of DD in this sample was 33.8% (grade I: 66%, grade II: 29% e grade III: 5%). LAVI increased progressively according to DD grade: 21 ± 4 mL/m² (absent), 26 ± 7 mL/m² (grade I), 33 ± 5 mL/m² (grade II), 50 ± 5 mL/m2 (grade III) (p < 0,001). In this sample, LAVI increase independent predictors were age, left ventricular mass, relative wall thickness, LV ejection fraction and E/e' ratio. CONCLUSION: DD contributes to left atrial remodeling. LAVI increases as an expression of DD severity and is independently associated to age, left ventricle hypertrophy, systolic dysfunction and increased LV filling pressures.

OBJETIVO: Avaliar a relação entre VAEi e diferentes graus de DD em pacientes brasileiros submetidos ao ecocardiograma, estudando os determinantes do aumento do VAEi nesta amostra. MÉTODOS: Selecionamos 500 pacientes ambulatoriais submetidos a ecocardiografia, após exclusão de arritmia, cardiopatia valvar ou congênita, marca-passo permanente ou janela ecocardiográfica inadequada. O VAEi foi obtido pelo método de Simpson; classificou-se a DD segundo diretrizes atuais. Variáveis clínicas e ecocardiográficas foram submetidas a análise multivariada de regressão linear. RESULTADOS: A idade média foi de 52 ± 15 anos, 53% do sexo masculino, 55% hipertensos, 9% coronariopatas, 8% diabéticos, 24% obesos, 47% com hipertrofia VE, fração de ejeção média do VE: 69,6 ± 7,2%. A prevalência de DD na amostra foi de 33,8% (grau I: 66%, grau II: 29% e grau III: 5%). Houve aumento progressivo das dimensões do VAEi conforme o grau de DD: 21 ± 4 mL/m² (ausente), 26 ± 7 mL/m² (grau I), 33 ± 5 mL/m² (grau II), 50 ± 5 mL/m2 (grau III) (p < 0,001). Os preditores independentes de aumento do VAEi nesta amostra foram idade, massa ventricular esquerda, espessura relativa de parede, fração de ejeção do VE e relação E/e'. CONCLUSÃO: A DD contribui para o remodelamento atrial esquerdo. O aumento do VAEi expressa a gravidade da DD e está associado de forma independente com idade, hipertrofia ventricular esquerda, disfunção sistólica e aumento das pressões de enchimento do VE.Universidade Federal de São Paulo (UNIFESP), Escola Paulista de Medicina (EPM)Medcenter CardiologiaUniversidade Federal do Espirito SantoUNIFESP, EPMSciELOSociedade Brasileira de Cardiologia - SBCUniversidade Federal de São Paulo (UNIFESP)Medcenter CardiologiaUniversidade Federal do Espirito SantoAouar, Lília Maria Mameri El [UNIFESP]Meyerfreud, DianaMagalhães, PedroRodrigues, Sérgio LamêgoBaldo, Marcelo PerimBrasil, YaraAouar, Sumaya Mameri ElAouar, Nabih Amin ElMill, José GeraldoCampos Filho, Orlando [UNIFESP]2015-06-14T13:45:31Z2015-06-14T13:45:31Z2013-07-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersion52-58application/pdfhttp://dx.doi.org/10.5935/abc.20130109Arquivos Brasileiros de Cardiologia.
