Abstract
OBJETIVOS: Verificar o perfil de alterações clínicas e, principalmente, laboratoriais hepáticas observadas em pacientes de cada uma das classes de insuficiência cardíaca. MÉTODOS: Por meio de um estudo seccional, foram pesquisados os dados clínicos e laboratoriais (alanina aminotransferase [ALT], aspartato aminotransferase [AST], fosfatase alcalina [FA], gama-glutamil transpeptidase [gama-GT], bilirrubinas e coagulograma) de 50 pacientes internados em 2002 em um hospital terciário com diagnóstico de insuficiência cardíaca. Os doentes foram separados de acordo com sua classe de insuficiência cardíaca e seus dados, comparados estatisticamente. Foram excluídos pacientes com hepatopatia de qualquer etiologia. RESULTADOS: A análise das médias de transaminases revelou aumento significativo apenas nos pacientes da classe IV. Por outro lado, a FA e a gama-GT apresentaram aumento progressivo de acordo com a classe de insuficiência cardíaca. CONCLUSÃO: A insuficiência cardíaca é caracterizada por perfil colestático progressivo de alterações laboratoriais, enquanto as transaminases se elevam apenas na insuficiência cardíaca mais avançada. O entendimento dessas alterações é fundamental para que se evite investigação hepática desnecessária em indivíduos com insuficiência cardíaca.
OBJECTIVES: To verify the clinical alterations and, in particular, hepatic laboratory alterations in patients in each of the heart failure (HF) functional classes. METHODS: The clinical and laboratory data - alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (AP), gamma-glutamyl transpeptidase (GGT), bilirubin and coagulogram - of 50 patients admitted in 2002 to a tertiary hospital with the diagnosis of heart failure were researched by means of a cross sectional study. The patients were separated in accordance with their HF class and their data were compared statistically. Patients with hepatopathy of any etiology were excluded. RESULTS: Analysis of the mean transaminase values revealed a significant increase only for the Class IV patients. On the other hand, alkaline phosphatase and GGT presented a progressive increase in accordance with the HF class. CONCLUSION: HF is characterized by a progressive cholestatic profile of laboratory alterations, while transaminase values are only elevated in advanced HF. It is of utmost importance to understand these alterations in order to avoid unnecessary hepatic investigations in individuals with heart failure.
