ABSTRACT
SUMMARY OBJECTIVE Monocyte count to HDL-C Ratio (MHR) and Fibrinogen to Albumin Ratio (FAR) have recently emerged as markers of inflammation in atherosclerotic diseases. Our goal was to investigate the relationships of MHR and FAR with the severity of carotid artery stenosis (CAS) in patients with asymptomatic carotid artery disease. METHODS This retrospective study consisted of 300 patients with asymptomatic CAS. Pre-angiographic MHR, FAR, and high-sensitive C-reactive protein (hsCRP) were measured. Carotid angiography was performed in patients with ≥50% stenosis on carotid ultrasonography. Patients were first split into 2 groups based on the degree of CAS and then tertiles (T) of MHR. RESULTS 96 patients had clinically insignificant CAS (<50%) (Group-1), and 204 patients had clinically significant CAS (≥50%) (Group-2). Group-2 had higher MHR, FAR, and hsCRP than group-1. Patients in T3 had higher MHR, FAR, and hsCRP than in T1 and T2. MHR, FAR, and hsCRP were correlated with each other (p<0.001, for all). MHR, FAR, and hsCRP were independent predictors of significant CAS. MHR better predicted a significant CAS than FAR and hsCRP (p<0.05). CONCLUSION Pre-angiographic MHR may be a better predictor than FAR and hsCRP in identifying a clinically significant carotid stenosis in patients with asymptomatic CAS. Patients with asymptomatic CAS and a high level of MHR should be followed-up closely to supervise risk-factor control and intensify treatment.
RESUMO
RESUMO OBJETIVO Recentemente, a contagem de monócitos para a proporção HDL-C (MHR) e a relação fibrinogênio para albumina (FAR) emergiram como marcadores de inflamação em doenças ateroscleróticas. Nosso objetivo é investigar a relação da MHR e FAR com a gravidade da estenose da artéria carótida (CAS) em pacientes com doença assintomática da artéria carótida. MÉTODOS Este estudo retrospectivo incluiu 300 pacientes com CAS assintomática. MHR pré-angiográfica, FAR e proteína C reativa de alta sensibilidade (hsCRP) foram medidas. A angiografia carotídea foi realizada em pacientes com estenose ≥50% na ultrassonografia carotídea. Os pacientes foram primeiramente divididos em dois grupos com base no grau de CAS e depois nos tercis (T) da MHR. RESULTADOS Noventa e seis pacientes apresentaram um CAS clinicamente insignificante (<50%) (grupo 1) e 204 pacientes apresentaram CAS clinicamente significativo (≥50%) (grupo 2). O grupo 2 apresentou MHR, FAR e hsCRP superior ao grupo 1. Pacientes em T3 apresentaram maior MHR, FAR e hsCRP do que em T1 e T2. MHR, FAR e hsCRP foram correlacionados entre si (p<0,001, para todos). MHR, FAR e hsCRP foram preditores independentes de CAS significativa. MHR predisse melhor uma CAS significativa que FAR e hsCRP (p<0,05). CONCLUSÕES A MHR pré-angiográfica pode ser um melhor preditor que a FAR e a hsCRP na identificação de estenose carotídea clinicamente significativa em pacientes com CAS assintomática. Pacientes com CAS assintomática e alto nível de MHR devem ser acompanhados de perto para supervisionar o controle dos fatores de risco e intensificar o tratamento.
