Background: Hemorheological and glycemic parameters and high density lipoprotein (HDL) cholesterol are used as biomarkers of atherosclerosis and thrombosis. Objective: To investigate the association and clinical relevance of erythrocyte sedimentation rate (ESR), fibrinogen, fasting glucose, glycated hemoglobin (HbA1c), and HDL cholesterol in the prediction of major adverse cardiovascular events (MACE) and coronary heart disease (CHD) in an outpatient population. Methods: 708 stable patients who visited the outpatient department were enrolled and followed for a mean period of 28.5 months. Patients were divided into two groups, patients without MACE and patients with MACE, which included cardiac death, acute myocardial infarction, newly diagnosed CHD, and cerebral vascular accident. We compared hemorheological and glycemic parameters and lipid profiles between the groups. Results: Patients with MACE had significantly higher ESR, fibrinogen, fasting glucose, and HbA1c, while lower HDL cholesterol compared with patients without MACE. High ESR and fibrinogen and low HDL cholesterol significantly increased the risk of MACE in multivariate regression analysis. In patients with MACE, high fibrinogen and HbA1c levels increased the risk of multivessel CHD. Furthermore, ESR and fibrinogen were significantly positively correlated with HbA1c and negatively correlated with HDL cholesterol, however not correlated with fasting glucose. Conclusion: Hemorheological abnormalities, poor glycemic control, and low HDL cholesterol are correlated with each other and could serve as simple and useful surrogate markers and predictors for MACE and CHD in outpatients.

Resumo Fundamento: Parâmetros hemorreológicos e glicêmicos e o HDL-colesterol são utilizados como biomarcadores da aterosclerose e trombose. Objetivo: Investigar a associação e a relevância clínica da velocidade de hemossedimentação (VHS), fibrinogênio, glicose de jejum, hemoglobina glicada (HbA1c) e HDL-colesterol na predição de eventos adversos cardiovasculares (EAC) importantes em pacientes ambulatoriais. Métodos: 708 pacientes estáveis ambulatoriais foram incluídos no estudo e acompanhados por um período médio de 28,5 meses. Os pacientes foram subdivididos em pacientes sem EAC e pacientes com EAC, que incluíram morte súbita cardíaca, infarto agudo do miocárdio, doença coronariana recém-diagnosticada, e acidente vascular cerebral. Comparamos os parâmetros hemorreológicos, glicêmicos, e perfis lipídicos entre os grupos. Resultados: Pacientes com EAC apresentaram níveis significativamente mais elevados de VHS, fibrinogênio, glicose de jejum, e HbA1c, e níveis mais baixos de HDL-colesterol em comparação a pacientes sem EAC. VHS e níveis de fibrinogênio elevados, e baixos níveis de HDL-colesterol aumentaram significativamente o risco de EAC em análise de regressão multivariada. Além disso, VHS e fibrinogênio correlacionaram-se positivamente com HbA1c e negativamente com HDL-colesterol, mas não se correlacionaram com glicose de jejum. Conclusão: Distúrbios hemorreológicos, baixo controle glicêmico e baixo nível de HDL-colesterol correlacionam-se entre si e podem ser usados como marcadores substitutos simples, úteis, e como preditores de EAC e doença coronariana em pacientes ambulatoriais.
