RESUMO
Resumo Fundamento Apesar dos avanços nas modalidades de diagnóstico e tratamento, há necessidade de marcadores preditivos para acidente vascular cerebral (AVC) recorrentes. Objetivos Este estudo teve como objetivo investigar a relação entre calcificação do arco aórtico (CAA) e recorrência de AVC em pacientes com AVC durante o acompanhamento de um ano. Métodos Todos os pacientes com AVC que sofreram seu primeiro evento foram avaliados para participação no estudo. Foram registrados pacientes que sofreram AVC recorrentes durante o acompanhamento de um ano. A CAA foi avaliada por radiografia de tórax. Com base na ocorrência de AVC recorrente, os pacientes foram divididos em dois grupos. A CAA foi classificada em quatro categorias de acordo com o seu grau, e a presença de CAA foi incluída na análise estatística. A relação entre CAA e AVC recorrente foi avaliada por meio de uma curva característica de operação do receptor. Um nível de significância <0,05 foi considerado aceitável para todas as análises estatísticas. Resultados Um total de 203 pacientes foram incluídos no estudo (46,8% mulheres, média de idade 69±12,3). AVC recorrente foi detectado em 49 pacientes. CAA, hipertensão e fibrilação atrial foram mais frequentes em pacientes com AVC recorrente. Pacientes com AVC recorrente apresentaram menor taxa de filtração glomerular e maior largura de distribuição de glóbulos vermelhos (RDW). Na análise de regressão multivariada, CAA (hazard ratio [HR], 3,544; IC 95%1,653-7,598, p=0,001) e RDW (HR,1,214; IC 95%1,053-1,400, p=0,008) foram identificados como preditores independentes de AVC recorrente. Conclusão A presença de CAA (≥ grau 1) e RDW foram significativamente associadas ao desenvolvimento de AVC recorrente dentro de um ano. Esses achados podem ter significado prognóstico no acompanhamento de pacientes com AVC.
ABSTRACT
Abstract Background Despite advances in diagnostic and treatment modalities, there is a need for predictive markers for recurrent strokes. Objectives This study aimed to investigate the relationship between aortic arch calcification (AAC) and stroke recurrence in stroke patients during a one-year follow-up. Methods All stroke patients who experienced their first event were evaluated for participation in the study. Patients who experienced recurrent strokes during the one-year follow-up were recorded. AAC was assessed by chest radiography. Based on the occurrence of recurrent strokes the patients were divided into two groups. AAC was classified into four categories according to its degree, and the presence of AAC was included in the statistical analysis. The relationship between AAC and recurrent stroke was assessed using a receiver operating characteristic curve. A significance level of <0.05 was deemed acceptable for all statistical analyses. Results A total of 203 patients were included in the study (46.8% female, mean age 69±12.3). Recurrent stroke was detected in 49 patients. AAC, hypertension, and atrial fibrillation were more frequent in patients with recurrent stroke. Patients with recurrent stroke had a lower glomerular filtration rate and a higher red cell distribution width (RDW). In multivariate regression analysis, AAC (hazard ratio [HR], 3.544; 95% CI1.653-7.598, p=0.001) and RDW (HR,1.214; 95% CI1.053-1.400, p=0.008) were identified as independent predictors of recurrent stroke. Conclusion The presence of AAC (≥ grade 1) and RDW were found to be significantly associated with the development of recurrent stroke within one year. These findings may have prognostic significance in the follow-up of stroke patients.
