The baseline data from GLORIA-AF phase 2 demonstrate that in newly diagnosed nonvalvular atrial fibrillation patients, NOAC have been highly adopted into practice, becoming more frequently prescribed than VKA in Europe and North America. Worldwide, however, a large proportion of patients remain undertreated, particularly in Asia and North America. (Global Registry on Long-Term Oral Antithrombotic Treatment in Patients With Atrial Fibrillation [GLORIA-AF]; NCT01468701).
This study provides some information on the characteristics of patients reporting palpitations to GPs who may have 'significant' cardiac arrhythmias. Based on this work, we believe that a larger community-based study would be worthwhile and would provide useful and useable clinical discriminant information for GPs in the settings where they work and amongst the types of patients they encounter.
Daily in the UK, frontline medical and paramedical staff are required to manage patients with “collapse?cause”. This universal colloquialism refers to patients who have had an abrupt loss of postural tone. Some of these patients would have had a “blackout” or a transient loss of consciousness (T-LOC). The three most important causes of T-LOC are syncope, epilepsy and psychogenic blackouts. Determining the correct cause is an important challenge; if the initial clinical diagnosis is wrong, investigations may be misdirected, and the final diagnosis and treatment incorrect. Syncope is much more common than epilepsy and may present with symptoms akin to the latter. This fact is not well appreciated and often leads to misdiagnosis. This article deals with the clinical features of the three main causes of blackouts, the value of investigations in arriving at a diagnosis and the problem of misdiagnosis. Pathways for managing patients presenting with blackouts are suggested.
Implantable loop recorder monitoring is likely to be a cost-effective strategy in people presenting to the UK NHS who are experiencing infrequent episodes of TLoC which either remain unexplained or are suspected to be arrhythmic after initial assessment and specialist cardiovascular assessment. Implantable loop recorder monitoring has been recommended by NICE for these populations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
