BACKGROUND AND PURPOSE The inter-relation between the size of patent foramen ovale (PFO) by transesophageal echocardiography (TEE) and the amount of microembolic signals (MES) on transcranial doppler (TCD) is still not determined. METHODS The study group comprised of 104 patients with first-ever ischaemic stroke or transient ischemic attack (TIA). Three(More)
BACKGROUND There is limited information about distribution of etiologies of ischemic stroke in different age groups. MATERIALS AND METHODS In this study, we applied the Trial of ORG 10172 in Acute Stroke Treatment (TOAST) classification in 87 patients aged < or = 45, and in 347 patients aged 46-60 years with first-ever ischemic stroke in order to follow(More)
Atrial fibrillation (AF) is a frequent complication of acute myocardial infarction (AMI). In the AMI setting, AF is frequently brief and attributed to acute haemodynamic changes, inflammation or ischaemia. However, it remains uncertain whether transient AF episodes are associated with a subsequent increased risk of ischaemic stroke. We studied the impact of(More)
BACKGROUND Data concerning hemodynamic status prior to and after carotid endarterectomy (CEA) in symptomatic and asymptomatic patients is insufficient. Transcranial Doppler (TCD) provides information regarding compensatory collateral flow as well as mechanisms of cerebral autoregulation in patients with carotid stenosis. PATIENTS AND METHODS Forty eight(More)
BACKGROUND Ethnic differences among first primary intracerebral hemorrhage (PICH) patients in an Israeli biethnic population have not yet been studied. PATIENTS AND METHODS We included in the study 546 patients (counting warfarin-related hemorrhages) hospitalized during the period from December 1999 through June 2008. RESULTS The mean age was 71.1 +/-(More)
BACKGROUND AND PURPOSE There is no information about the optimal position of a patient for the performance of a transcranial Doppler (TCD) examination to detect patent foramen ovale (PFO). Such information is important to improving the sensitivity of the test in comparison to the gold standard of transesophageal echocardiography (TEE). METHODS Thirty-four(More)
Cognitive decline has recently been found to be associated with microemboli in cerebral vessels in patients with artificial heart valves. The authors sought to determine the nature of such microemboli, that is, whether they are gaseous or solid, by comparing their characteristics to those of artificially generated air emboli in patients with patent foramen(More)
