INTRODUÇÃO: Índices calculados a partir de medidas laboratoriais e a determinação de marcadores plasmáticos são frequentemente utilizados para a avaliação do risco cardiovascular. OBJETIVO: Utilizar a razão triglicérides/colesterol da lipoproteína de alta densidade (HDL-C), estimativa de tamanho de partículas de lipoproteína de baixa densidade (LDL) e os níveis da proteína C reativa de alta sensibilidade (PCR-as) para a avaliação clínica e laboratorial do risco cardiovascular de pacientes com doença arterial coronariana (DAC). MATERIAL E MÉTODOS: Foram selecionados 60 pacientes por conveniência, 36 do sexo feminino (F) (65 ± 9 anos) e 24 do sexo masculino (M) (55 ± 10 anos) com diagnóstico de cardiopatia isquêmica estável, atendidos no Hospital Ana Neri, em Salvador, Bahia. A investigação foi realizada no Laboratório de Bioquímica Clínica da Faculdade de Farmácia da Universidade Federal da Bahia (UFBA). Amostras de sangue foram coletadas após 12 horas de jejum para determinação da PCR-as, do perfil lipídico e do cálculo de indicadores de risco. As determinações foram realizadas no equipamento Syncron LX®20 Beckman Coulter, USA. Foram considerados significativos os resultados da análise inferencial para p INTRODUCTION: Calculated indexes from laboratory measurements and the determination of plasma markers are commonly used in cardiovascular risk assessment. OBJECTIVE: To use triglycerides/high-density lipoprotein cholesterol (HDL-C) ratio, estimate of low-density lipoprotein (LDL) particle size and high sensitive C-reactive protein (hs-CRP) levels to the clinical and laboratorial assessment of coronary risk among patients with coronary disease. MATERIAL AND METHODS: Sixty patients were chosen accordingly, 36 female (F) (65 ± 9 years of age) and 24 male (M) (55 ± 10 years of age) diagnosed with stable ischemic cardiopathy at Ana Neri Hospital, Salvador, Bahia, Brazil. The investigation was carried out at the Clinical Biochemistry Laboratory of the College of Pharmacy at Federal University of Bahia (UFBA). Blood samples were collected after a 12-hour fast to determine hs-CRP, lipid profile and risk indicators. All data were assessed through Syncron LX®20 Beckman Coulter. The inferential analysis results were considered significant when p < 5%. Data analysis was carried out with GraphPad Prism® (4.03 version) software. RESULTS: Data analysis showed a positive correlation between hs-CRP and triglycerides/HDL-C ratio only among women (r = 0.4; p = 0.0442), n = 36. The analysis of other parameters did not show any significance. CONCLUSION: The triglycerides/HDL-C ratio and hs-CRP may be used as indicators of increase in cardiovascular risk among women with coronary artery disease (CAD).
