RESUMO
INTRODUCTION: Among stroke patients with atrial fibrillation (AF), it is not uncommon to identify carotid atherosclerosis. This study aimed to estimate the prevalence of, and factors associated with, carotid atherosclerosis among patients with AF and acute ischemic stroke. PATIENTS AND METHODS: Prospectively collected data from consecutive patients with anterior ischemic stroke and AF who underwent carotid imaging from 10 stroke registries were categorized retrospectively according to the degree of stenosis in: no atherosclerosis, stenosis <50%, stenosis ≥50%, and occlusion. Logistic regression analysis was used to identify factors associated with ipsilateral carotid atherosclerosis. RESULTS: Among 2,955 patients with ischemic stroke and AF, carotid atherosclerosis was evident in 1,022 (34.6%) patients, while carotid stenosis ≥50% and occlusion were identified in 204 (6.9%) and 168 (5.7%) patients, respectively. Ipsilateral carotid stenosis ≥50% or occlusion was associated with higher age (OR: 1.15, 95% CI: 1.01-1.32, per decade), previous ischemic stroke or transient ischemic attack (OR: 1.70, 95% CI: 1.29-2.25), peripheral artery disease (OR: 1.85, 95% CI: 1.23-2.78), coronary artery disease (OR: 1.53, 95% CI: 1.16-2.04), and statin treatment on admission (OR: 1.30, 95% CI: 1.01-1.67). Patients with lacunar stroke had a lower likelihood of stenosis ≥50% or occlusion (OR: 0.29, 95% CI: 0.13-0.68). Compared to the absence of atherosclerotic disease, atherosclerosis in one and two arterial beds was associated with the identification of ipsilateral carotid stenosis (OR: 1.49, 95% CI: 1.22-2.98 and OR: 3.18, 95% CI: 1.85-5.49, respectively). CONCLUSION: Among acute ischemic stroke patients with AF, 1 out of 3 had ipsilateral carotid atherosclerosis, and 1 out of 8 had ipsilateral carotid stenosis ≥50% or occlusion. Atherosclerosis in two arterial beds was the most important predictor for the identification of ipsilateral carotid stenosis. Among ischemic stroke patients with AF, carotid atherosclerosis is common, while carotid imaging should not be overlooked, especially in those with coronary or/and peripheral artery disease.
RESUMO
The COVID-19 pandemic and preventive and compulsory social isolation (PCSI) have generated changes in the organization and use of the health system around the world. We analyze the impact of the health situation on the number of outpatient visits, hospitalizations and access to revascularization therapy for cerebrovascular disease. The period from March 1 to July 31, 2020 was analyzed. It was compared with the same period in 2019. Total outpatient and hospital visits were evaluated, NIHSS scale (National Institute of Health Stroke Scale) upon admission, type of cerebrovascular disease and use of revascularization therapies; 197 patients with acute cerebrovascular events were admitted in 2019 and 150 patients in 2020. There was a significant decrease in the number of hospitalizations for total ischemic events and transient ischemic attacks in the comparison of 5 months. An increase in cerebral venous thrombosis and cerebral hemorrhages was also seen. Access to intravenous fibrinolysis and mechanical thrombectomy remained stable, but with prolonged door-to-needle time. Outpatient visits fell 67%, the decrease being greater in April and more marked in follow-up visits. The number of hospitalizations and outpatient visits during the PCSI dropped substantially. This seems to be due to strict compliance with quarantine and not to pathophysiological mechanisms related to COVID-19. The population should be educated about the need to control chronic diseases and acute events and safety measures should be guaranteed in health centers.
La pandemia por COVID-19 y el aislamiento social preventivo y obligatorio (ASPO) han generado cambios en la organización y utilización del sistema de salud en todo el mundo. Analizamos el impacto de la situación sanitaria en el número de consultas ambulatorias, internaciones y acceso a terapias de revascularización por enfermedad cerebrovascular. Se analizó el período desde el 1 marzo al 31 de julio de 2020. Se comparó con el mismo período de 2019. Se evaluaron total de consultas ambulatorias e internaciones, escala NIHSS (National Institute of Health Stroke Scale) al ingreso, tipo de enfermedad cerebrovascular y uso de terapias de revascularización. Ingresaron 197 pacientes con eventos cerebrovasculares agudos en 2019 y 150 pacientes en 2020. Hubo un descenso significativo en el número de internaciones por eventos isquémicos totales y accidentes isquémico transitorios en el comparativo de los 5 meses. Se vio además un aumento en trombosis venosas cerebrales y hemorragias cerebrales. El acceso a fibrinolisis intravenosa y trombectomía mecánica se mantuvo estable, pero con prolongación del tiempo puerta-aguja. Las consultas ambulatorias descendieron 67%, siendo mayor el descenso en abril y más marcado en consultas de seguimiento. El número de internaciones y de consultas ambulatorias durante el ASPO descendió sustancialmente. Esto pareciera obedecer al cumplimiento estricto de la cuarentena y no a mecanismos fisiopatológicos rel acionados con el COVID-19. Debe educarse a la población sobre la necesidad del control de enfermedades crónicas y de eventos agudos y se deben garantizar medidas de seguridad en los centros de salud.
