We aimed to investigate the association between plasma homocysteine and obstructive sleep apnoea (OSA) syndrome in patients with ischaemic stroke. A total of 102 patients with ischaemic stroke were classified into four OSA groups based on their apnoea-hypopnoea index (AHI): absent (AHI < 5/hour); mild (5-14/hour); moderate (15-30/hour); and severe (>(More)
We aimed to investigate the risk factors for haemodynamic depression (HD) during and after carotid artery stenting (CAS). A total of 251 patients with CAS, enrolled between June 2004 and December 2008, were divided into two groups according to periprocedure observations: (i) a group with HD (systolic blood pressure<90 mm Hg and heart beat rate<50/ beats per(More)
We aimed to investigate the complications and predictors associated with persistent hemodynamic depression (PHD) after carotid artery stenting (CAS). A total of 204 patients undergoing CAS in two centers between January 2011 and November 2013 were enrolled for study into two cohorts: PHD (systolic blood pressure <90 mm Hg and heart beat rate <60/min, which(More)
OBJECTIVES Clinical-diffusion magnetic resonance imaging (MRI) mismatch (CDM) in patients with anterior circulation occlusions is an optional method used to select patients for recanalisation outside the 3-h time window. A similar concept has not been reported with posterior circulation occlusions. METHODS CDM was defined as a Glasgow Coma Scale (GCS)(More)
This study was designed to investigate the risk factors and complications of difficult retrieval (DR) of embolic protection devices (EPDs) in carotid artery stenting (CAS). A total of 195 consecutive patients who underwent CAS between December 2007 and March 2010 in a general hospital were enrolled and divided into two groups: with DR and without DR. The(More)
We thank Polesel and colleagues [1] for their interest in our study [2]. Considering that some sleep disorders such as obstructive sleep apnea (OSA) are related to atherosclerosis, we think their suggestion that employing a sleep questionnaire to evaluate the possible cause of carotid atherosclerosis is interesting and of clinical importance. As Polesel and(More)
