ABSTRACT
Abstract

Background:

Coronary artery fistula (CAF) is an abnormal connection that links a coronary artery to a cardiac chamber or another major blood vessel. Several studies have shown the association between mean platelet volume (MPV) and cardiovascular diseases. In the literature, there is no previous study about the association between hematologic parameters and congenital CAF. For this reason, we aimed to investigate the association of MPV with CAF.

Methods:

70 patients with normal coronary arteries and 50 with coronary artery fistulas were included. Routine blood and biochemical parameters were measured before the arteriography. Differences between groups for continuous variables were analyzed with t- test or Mann-Whitney test. P values < 0.05 were considered significant. Regression analysis was used to find independent predictors of CAF.

Results:

Baseline patient demographics, including age and clinical risk factors, were similar between the groups. Compared to the control group, median (IQR) High-density lipoprotein cholesterol (HDL) levels were significantly higher (p=0.04) and MPV levels were significantly lower in the CAF group (8.84 ± 1.71fL vs. 10.43 ± 1.34, p < 0.001). In the multivariate analysis, only MPV was a significant predictor of CAF (p < 0.001, 95% CI for OR 0.438 (0.306-0.629). A negative correlation was found between MPV and fistulae in Pearson's correlation test (r -0.454, p < 0.001). An MPV level of < 9,6 fL showed sensitivity, specificity, positive predictive value and negative predictive value of 80%, 68%, 71% and 78% respectively (AUC = 0.766, 95% CI, 0.678-0.854) for the prediction of CAF.

Conclusion:

The present study suggests that MPV may decrease in patients with CAF.
RESUMO
Resumo Fundamento A fístula da artéria coronária (FAC) é uma conexão anormal que liga a artéria coronária a uma câmara cardíaca ou outro importante vaso sanguíneo. Vários estudos mostraram a associação entre o volume plaquetário médio (VPM) e as doenças cardiovasculares. Na literatura, não há estudo prévio sobre a associação entre os parâmetros hematológicos e a FAC congênita. Por essa razão, nosso objetivo foi investigar a relação do VPM com a FAC.

Métodos:

Foram incluídos 70 pacientes com artérias coronárias normais e 50 com fístulas de artérias coronárias. Os parâmetros sanguíneos e bioquímicos de rotina foram medidos antes da arteriografia. As diferenças entre os grupos para as variáveis contínuas foram analisadas com o teste t ou teste de Mann-Whitney. Valores de p < 0,05 foram considerados significativos. A análise de regressão foi utilizada para encontrar preditores independentes de FAC.

Resultados:

Os dados demográficos basais dos pacientes, incluindo idade e fatores de risco clínicos, foram semelhantes entre os grupos. Comparados à mediana do grupo controle (IIQ), os níveis de HDL-colesterol foram significativamente mais altos (p = 0,04) e os níveis de VPM foram significativamente mais baixos no grupo FAC (8,84 ± 1,71fL vs. 10,43 ± 1,34, p < 0,001). Na análise multivariada, apenas o VPM foi um preditor significativo de FAC (p<0,001, IC 95% para OR 0,438 (0,306-0,629)). Foi encontrada uma correlação negativa entre o VPM e fístulas no teste de correlação de Pearson (r -0,454, p < 0,001). Um nível de VPM < 9,6 fL apresentou sensibilidade, especificidade, valor preditivo positivo e valor preditivo negativo de 80%, 68%, 71% e 78%, respectivamente (AUC = 0,766, IC 95%, 0,678-0,854) para a previsão de FAC.

Conclusão:

O presente estudo sugere que o VPM pode diminuir no paciente com FAC.
