Atrial fibrillation (AF) in the most common cardiac arrhythmia, and is associated with an increased risk of thromboembolic events. Silent AF is an asymptomatic form of AF incidentally diagnosed during a routine test or manifesting as an arrhythmia-related complication. Although recent trials have clearly demonstrated that patients with sub-clinical AF are at increased risk of stroke, the real i...
Silent Brain Infarcts (SBI) are associated with an increased risk of subsequent stroke. SBI are incidentally revealed by CT or MRI executed in stroke patients. A prospective study was undertaken involving 200 consecutive patients aged >45 years with brain infarct admitted in University of Alberta Hospital, Canada (100 patients) and Valie-Asr Hospital, Iran (100 patients) in 2003. Patients w...
With advances in brain imaging and completion of randomized clinical trials (RCTs) for primary and secondary stroke prevention, the natural history of central nervous system (CNS) complications in sickle cell disease (SCD) is evolving. In order of current prevalence, the primary CNS complications include silent cerebral infarcts (39% by 18 years), headache (both acute and chronic: 36% in childr...
BACKGROUND AND PURPOSE Silent brain infarctions are associated with an increased risk of stroke in healthy individuals. Risk of recurrent stroke in patients with both symptomatic and silent brain infarction (SBI) has only been investigated in patients with cardioembolic stroke in the European Atrial Fibrillation Trial. We assessed whether patients with recent noncardioembolic stroke and SBI det...
BACKGROUND Silent brain infarcts are detected by neuroimaging in up to 20% of asymptomatic patients based on population studies. They are five times more frequent than stroke in general population, and increase significantly both with advancing age and hypertension. Moreover, they are independently associated with the risk of future stroke and cognitive decline.Despite these numbers and the cli...
S troke after aortic valve surgery is known as a devastating complication and is associated with increased morbidity and mortality. 1 Transcatheter aortic valve replacement (TAVR) has emerged as a valid alternative for surgical aortic valve replacement (SAVR) both in inoperable patients and in those at high risk for surgery; however, the encouraging results were hampered by various complication...
BACKGROUND AND PURPOSE Clinical significance of silent microbleeds is unknown in moyamoya disease. This study was aimed to clarify the incidence, locations, and longitudinal course. METHODS This prospective cohort study included 78 nontreated patients with moyamoya disease. The incidence and locations of silent microbleeds were evaluated on T2*-weighted MRI. MR examinations were repeated ever...
BACKGROUND AND PURPOSE Incidental findings of infarcts on brain imaging are common, but their clinical significance is not clear. We examined the prevalence of symptomatic and silent infarcts on cranial computerized tomography (cCT) and their relation to dementia and mortality in a representative sample of 239 85-year-olds living in Gothenburg Sweden. METHODS Information on stroke was obtaine...
