BACKGROUND The early detection of cardiac syncope is challenging. We aimed to evaluate the diagnostic value of 4 novel prohormones, quantifying different neurohumoral pathways, possibly involved in the pathophysiological features of cardiac syncope: midregional-pro-A-type natriuretic peptide (MRproANP), C-terminal proendothelin 1, copeptin, and midregional-proadrenomedullin. METHODS AND RESUL...
OBJECTIVES The purpose of this study was to assess the importance of syncope as a warning sign for sudden death in advanced heart failure and to determine the relative importance of cardiac syncope and syncope from other causes. BACKGROUND Despite remarkable advances in the pharmacologic approach to advanced heart failure, 20% to 40% of patients with advanced heart failure will die each year....
BACKGROUND The congenital long-QT syndrome (LQTS) is an important cause of sudden cardiac death in children without structural heart disease. However, specific risk factors for life-threatening cardiac events in children with this genetic disorder have not been identified. METHODS AND RESULTS Cox proportional-hazards regression modeling was used to identify risk factors for aborted cardiac ar...
We report a case of a 75-year-old male with history of lung adenocarcinoma who presented with shortness of breath and frequent episodes of cough-induced syncope. A large pericardial effusion was found on echocardiogram suggestive of cardiac tamponade. Pericardiocentesis was done which improved the dyspnea and eventually resolved the syncope. There are only two other cases reported in the litera...
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 Pediatric syncope is common. Cardiac causes are rarely found. We describe and assess a pragmatic approach to these patients first seen by a pediatric cardiologist in the New England region, using Standardized Clinical Assessment and Management Plans (SCAMPs). METHODS AND RESULTS Ambulatory patients aged 7 to 21 years initially seen for syncope at participating New England Congenita...
Syncope, a common symptom of cerebral ischemia often shows a multifactorial etiopathogenesis. Although inherited arrhythmias causing syncope is uncommon, such an occurrence could be a warning sign preceding cardiac arrest. Long QT syndrome (LQTS) is a typical inherited arrhythmia causing syncope in children. Early diagnosis and treatment of LQTS using beta-blockers prevents recurrent syncope in...
UNLABELLED Syncope is a common complaint in clinical medical care. The etiology and mechanism can be complex. We report two cases experienced recurrent syncope to our emergency room without concomitant symptom. The image studies of both cases revealed apical neoplasms compress left common carotid artery with mediastinal lymphadenopathy and without cardiac/main artery trunk involved. After brain...
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...
INTRODUCTION Syncope and sudden cardiac arrest are known complications of aortic stenosis (AS). OBJECTIVES The aim of the study was to investigate the incidence of these complications in patients with severe symptomatic AS and to analyze whether basic clinical data and electrocardiographic (ECG) and echocardiographic parameters can be the markers of these complications. PATIENTS AND METHO...
