Digoxina, Mortalidade, IdosoResumo
Objetivou-se descrever as taxas de mortalidade e sobrevida de idosos com insuficiência cardíaca que fizeram uso de digoxina, bem como identificar os fatores de risco associados à mortalidade. Prontuários de pacientes idosos (≥60 anos) atendidos no ambulatório de cardiologia para insuficiência cardíaca e que fizeram uso de digoxina foram triados e selecionados para este estudo retrospectivo. Variáveis sociodemográficas e clínicas foram mensuradas. A sobrevida foi verificada pelas curvas de Kaplan-Meier e teste log-rank. A regressão logística múltipla ajustada foi utilizada para avaliar os potenciais fatores de risco associados à mortalidade. Dos 65 prontuários analisados a sobrevida foi menor nos pacientes que utilizavam a dosagem de 0,125mg (p=0,093). A taxa de mortalidade foi de 35,9% e as chances de óbitos aumentaram nos indivíduos com idade acima de 76 anos (p=0,010; ORaj: 4,021), que possuíam outras doenças cardíacas (p=0,004; ORaj: 5,943) e com maior tempo de uso da digoxina (p=0,047; ORaj: 1,164).
