Introdução: A fibrilhação auricular é a arritmia sustentada mais comum na população adulta com significado clínico, representando um importante problema de saúde pública. Não existe na literatura dados publicados acerca da prevalência da fibrilhação auricular em Angola. Objetivo: O presente estudo foi realizado com o objetivo de determinar a prevalência de fibrilhação auricular numa população do Bengo, uma província do norte de Angola, estratificada por sexo e idade e análise da sua relação com alguns fatores de risco cardiovascular. Materiais e Métodos: Os dados são provenientes do estudo CardioBengo, um estudo transversal de base comunitária, do qual foi selecionada uma amostra aleatória de indivíduos com idades compreendidas entre os 15 e os 84 anos. No total foram incluídos 2 379 indivíduos na análise final. Resultados: A idade média dos participantes foi de 35 anos e 63% da amostra era do sexo feminino. Verificou-se que a frequência de consumo de álcool era de 35,8%, a prevalência de acidente vascular isquémico ou acidente isquémico transitório foi de 0,4%; insuficiência cardíaca congestiva, 0,3%; doença cardíaca isquémica, 0,3% e hipertrofia ventricular esquerda, 37,2%. A fibrilhação auricular foi identificada em dois indivíduos, o que representa uma prevalência de 0,084%. Conclusão: O nosso estudo mostra uma baixa prevalência de fibrilhação auricular, quando comparada com as encontradas em estudos realizados em países desenvolvidos, mas semelhante à encontrada em estudos da África Subsariana.
ABSTRACT - Introduction: Atrial fibrillation is the most common sustained arrhythmia of clinical significance in the adult population, representing an important public health problem. Literature on the prevalence of atrial fibrillation in Angola is unavailable. Objective: The goal of this paper is to determine the prevalence of atrial fibrillation in a population from Bengo, a province from northern Angola, stratified by sex and age and analyze its relationship with some cardiovascular risk factors. Material and Methods: The data were obtained from the CardioBengo study, a cross-sectional community-based study, from which a random sample of individuals aged between 15 and 84 years was selected. In total, 2,379 individuals were included in the final analysis. Results: The average age of the participants was 35 years old, and 63% of the sample was female. The following prevalence rates were noted: prior stroke or transient ischaemic attack, 0.4%; congestive heart failure, 0.3%; ischaemic heart disease, 0.3% and left ventricular hypertrophy, 37.2%. Atrial fibrillation was found in two individuals, reflecting a prevalence of 0.084%. Conclusion: Our study reports a low prevalence of atrial fibrillation compared to rates found in studies conducted in developed countries but similar to other studies from Sub-Saharan Africa.
