Introdução: A Fibrilação Auricular (FA) é a arritmia sustentada mais comum na população adulta. O objectivo desta pesquisa é determinar a frequência, etiologia, evolução, tratamento e evolução dos pacientes diagnosticados com FA internados por insuficiência cardíaca (IC) num hospital terciário em Luanda, Angola.
Métodos: Trata-se de um estudo descritivo, transversal e retrospectivo, sobre o perfil clínico de pacientes diagnosticados com FA internados por IC num hospital público terciário de Luanda, Angola. A normalidade da distribuição dos dados foi analisada por meio do teste de Kolmogorov-Smirnov. As variáveis qualitativas foram expressas em frequências absolutas e relativas. As variáveis quantitativas foram expressas como média ± desvio padrão (DP) ou mediana.
Resultados: Dos 461 pacientes internados com IC, 32 (6,9%) indivíduos foram diagnosticados com FA. A média de idade dos participantes foi de 59,56±15,9 anos e 65,6% da amostra era do sexo feminino. Os principais factores de risco foram hipertensão arterial (68,8%) e hábitos alcoólicos (46,9%). As principais causas de IC foram cardiopatia hipertensiva, 19(59,4%), cardiomiopatia dilatada, 8(25%) e valvulopatia mitral reumática, 5(15,6%). Foi prescrita previamente varfarina em 8(25%) indivíduos e aspirina em 21(65,6%), betabloqueador em 15(46,9%) indivíduos, digoxina em 14(43,8%) e amiodarona em (9,4%). As complicações mais frequentes foram: acidente vascular cerebral em 15(46,8%), ocorreram 6 óbitos (18,75%).
Conclusão: O nosso estudo mostra uma baixa frequência de fibrilhação auricular em doentes com IC em comparação com a encontrada em estudos semelhantes na África Subsaariana.
