Background—The primary aim and central hypothesis of the study are that a designated syncope unit in the emergency department improves diagnostic yield and reduces hospital admission for patients with syncope who are at intermediate risk for an adverse cardiovascular outcome. Methods and Results—In this prospective, randomized, single-center study, patients were randomly allocated to 2 treatmen...

PURPOSE Syncope is an atypical presentation for acute pulmonary embolism (APE). There are conflicting data concerning syncope and prognosis of APE. PATIENTS AND METHODS One hundred and seventy-nine consecutive patients aged 22-96 years (median, 68 years) with APE were retrospectively enrolled in the study. RESULTS Prevalence of syncope was 13% (n=23) at the time of presentation. Compared to...

Abstract The cause of syncope remains unknown in about 40% of cases after extensive investigations. Elderly patients are at increased risk of syncope because of the physiologic changes due to aging, higher incidence of chronic illness and the use of a greater number of medications that may contribute to hypotension. Syncope is common, difficult to evaluate and has a high morbidity and mortality...

BACKGROUND Syncope is a clinical event characterized by a transient loss of consciousness, estimated to affect 6.2/1000 person-years, resulting in remarkable health care and social costs. Human pathophysiology suggests that heat may promote syncope during standing. We tested the hypothesis that the increase of air temperatures from January to July would be accompanied by an increased rate of sy...

BACKGROUND The prognostic significance of syncope has not been investigated systematically in hypertrophic cardiomyopathy, and treatment strategies have been based largely on intuition and experience. METHODS AND RESULTS We assessed the relationship between syncope and sudden death in 1511 consecutive patients with hypertrophic cardiomyopathy. Unexplained (n=153) or neurally mediated (n=52) s...

OBJECTIVES To investigate the etiology of transient loss of consciousness (T-LOC) suspected to be syncope and unexplained falls in elderly adults with dementia. DESIGN Prospective, observational, multicenter study. SETTING Acute care wards, syncope units or centers for the diagnosis of dementia. PARTICIPANTS Individuals aged 65 and older with a diagnosis of dementia and one or more episod...

Nikola RADOVANOVIĆ Pacemaker Center Clinical Center of Serbia Dr Koste Todorovića 8 11000 Belgrade Serbia [email protected] SUMMARY Introduction Vasovagal syncope is the most common type of reflex syncope. Efficacy of cardiac pacing in this indication has not been the subject of many studies and pacemaker therapy in patients with vasovagal syncope is still controversial. Objective This study ...

Syncope in the general population is a frequent event often leading to hospitalization, but it is unclear whether syncope in the general population is an independent risk marker for adverse prognosis. In this review, we investigate the current literature and evaluate the prognosis and impact of syncope on adverse outcomes including death and recurrences across different populations with focus o...

BACKGROUND Differential diagnosis between syncope and epilepsy in patients with transient loss of consciousness of uncertain etiology is still unclear. Thus, the aim of the present work is to evaluate the prevalence of syncope in patients with "possible" or "drug-resistant" epilepsy. METHODS The Overlap between Epilepsy and SYncope Study (OESYS) is a multicenter prospective observational stud...

Syncope is a clinical syndrome defined as a relatively brief self-limited transient loss of consciousness (TLOC) caused by a period of inadequate cerebral nutrient flow. Most often the trigger is an abrupt drop of systemic blood pressure. True syncope must be distinguished from other common non-syncope conditions in which real or apparent TLOC may occur such as seizures, concussions, or acciden...
