Pulmonary opacities are described in many chest radiograph reports in stroke patients and are often asymptomatic. The aim of this study is to investigate the clinical features associated with asymptomatic pulmonary opacities (APO) and evaluate APO prognostic value in ischemic stroke. Methods: We prospectively analyzed patients with acute ischemic stroke without pneumonia symptoms referred to our stroke center. All patients underwent a chest x-ray within 48 hours after admission. We divided patients with APO (defined as asymptomatic area of increased pulmonary attenuation) and patients without APO. Firstly, we compared clinical, laboratory, and echocardiographic parameters between groups; secondly,APO were evaluated as a possible predictor of the neurological severity at discharge and functional outcome at 90 days. Results: We included 162 patients, 78 of whom had APO. On univariate analysis, we observed a significant difference between patients with APO and patients without APO in terms of neutrophils (73,56§ 10,10 vs 69,72§12,29; p=0,031), atrial fibrillation (AF, paroxysmal 27,4% vs 25,6%; permanent 19% vs 2,6%; p<0,002), cardioembolic etiology (37,2% vs 22,7%, p <0,033), thrombectomy (58,3% vs 42,9%, p <0,05), dysphagia/vomit (34,5% vs 14,10%, p<0,005), admission NIHSS (14,20§5,98 vs 10,29§5,82, p=0,001), discharge NIHSS (8,68§6,73 vs 5,64§6,20; p=0,003), and 90 days mRS (3,47§2,12 vs 2,31§ 1,93; p=0,001). On multivariate analysis, APO were significantly associated with admission NIHSS and AF. APO were a predictor of outcome on univariate analysis, but not on multivariate. Conclusion: APO in acute ischemic stroke are associated with AF. APO were not a predictor of neurological and functional outcome.

Abstract

Pulmonary opacities are described in many chest radiograph reports in stroke patients and are often asymptomatic. The aim of this study is to investigate the clinical features associated with asymptomatic pulmonary opacities (APO) and evaluate APO prognostic value in ischemic stroke. Methods: We prospectively analyzed patients with acute ischemic stroke without pneumonia symptoms referred to our stroke center. All patients underwent a chest x-ray within 48 hours after admission. We divided patients with APO (defined as asymptomatic area of increased pulmonary attenuation) and patients without APO. Firstly, we compared clinical, laboratory, and echocardiographic parameters between groups; secondly,APO were evaluated as a possible predictor of the neurological severity at discharge and functional outcome at 90 days. Results: We included 162 patients, 78 of whom had APO. On univariate analysis, we observed a significant difference between patients with APO and patients without APO in terms of neutrophils (73,56§ 10,10 vs 69,72§12,29; p=0,031), atrial fibrillation (AF, paroxysmal 27,4% vs 25,6%; permanent 19% vs 2,6%; p<0,002), cardioembolic etiology (37,2% vs 22,7%, p <0,033), thrombectomy (58,3% vs 42,9%, p <0,05), dysphagia/vomit (34,5% vs 14,10%, p<0,005), admission NIHSS (14,20§5,98 vs 10,29§5,82, p=0,001), discharge NIHSS (8,68§6,73 vs 5,64§6,20; p=0,003), and 90 days mRS (3,47§2,12 vs 2,31§ 1,93; p=0,001). On multivariate analysis, APO were significantly associated with admission NIHSS and AF. APO were a predictor of outcome on univariate analysis, but not on multivariate. Conclusion: APO in acute ischemic stroke are associated with AF. APO were not a predictor of neurological and functional outcome.
