Abstract

Mechanical thrombectomy (MT) is one of the aetiological treatment options recommended for anticoagulated patients with acute ischaemic stroke (AIS). We analysed its long-term outcomes using the modified Rankin Score (mRS) or mortality on day 90. Data describing the anticoagulant efficacy and safety of MT in patients with AIS is limited. This study included 291 patients with AIS (49% women, mean [SD] age 66 [15] years) who underwent MT in the Comprehensive Stroke Centre in Krakow, Poland. Data describing demographics, stroke risk factors, NIHSS on admission, postprocedural thrombolysis in cerebral infarction score, 24-hour postprocedural haemorrhagic transformation (ECASS-2) as seen on computed tomography, and time between stroke onset and groin puncture was collected. The outcome measure was the mRS on day 90 after stroke onset (a favourable outcome was defined as an mRS not exceeding 2 points; an unfavourable outcome was death). Thirty-seven patients (13%) were on therapeutic anticoagulation during MT. Univariate analysis showed that anticoagulated patients were older and more likely to have been diagnosed with hypertension, ischaemic heart disease, or atrial fibrillation. The patient groups did not differ in terms of clot loc...Continue Reading

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.

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.
