Abstract

Non-vitamin K antagonist oral anticoagulants (NOACs) have gained increasing importance for stroke prevention in patients with non-valvular atrial fibrillation (AF). With changing prescription practice, among other factors, clinicians can expect to see rising numbers of patients with ischemic stroke and pre-existing NOAC therapy. Few data exist regarding a potential impact of NOAC on stroke severity and outcome. To evaluate the impact of pre-admission NOAC therapy on ischemic stroke severity. Retrospective analysis of medical data of 376 patients with newly detected AF or known AF with either no pre-admission oral anticoagulation (n = 277) or existing NOAC therapy (n = 99; Apixaban, n = 33, Dabigatran, n = 16; Edoxaban, n = 1; Rivaroxaban, n = 49) consecutively admitted for acute ischemic stroke between January 2015 and December 2016. Patients with pre-admission NOAC had significantly more often experienced a prior stroke than patients not on NOAC therapy (45.5 vs. 18.4%, p < 0.001) and were significantly more frequently non-smokers (1.0 vs. 7.2%, p = 0.021). Significantly more patients without pre-admission NOAC received thrombolysis (33.8 vs. 8.1%, p < 0.001). Pre-admission NOAC therapy was associated with significantly lower ...Continue Reading

Brain Ischemia

Brain ischemia is a condition in which there is insufficient blood flow to the brain to meet metabolic demand. Discover the latest research on brain ischemia here.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.
