Abstract
BACKGROUND AND PURPOSE: Intracerebral hemorrhage (ICH) is the most disastrous stroke subtype. Prognosis is considered worse with prior antithrombotic treatment. Our aim was to evaluate the association of prior antithrombotic treatment on the radiological and clinical outcome after ICH in a subgroup of patients included in a national registry. METHODS: Based on the National Acute Stroke Israeli (NASIS) registry during 2004, 2007, 2010, and 2013 (2-month periods), characteristics, volumetric parameters, and prognosis of a subgroup of patients with ICH were analyzed. RESULTS: Among the 634 patients with ICH in the NASIS registry, 310 (49%) were not treated previously with antithrombotic medications, 232 (37%) were treated with an antiplatelet agent, and 92 (14.5%) patients were on oral anticoagulant therapy, of them 30 patients (33%) with an international normalised ratio (INR) value below 2, 33 (36%) patients with an INR value of 2-3, and 29 patients (31%) with an INR value above 3 upon admission. Patients with deep hemorrhage on prior anticoagulants treatment had the highest probability for poor outcome at hospital discharge. Patients with low bleeding volume (0-30 cm3), were likely to have admission National Institute of Health Stroke Scale < 10 (62%), while those with higher volumes (30-59 cm3 and > 60 cm3), had only 16.7% and 14.3% chance, respectively. We did not observe a significant difference between prior antithrombotic treatment and functional outcome at discharge, yet prior anticoagulant treatment was associated with higher long-term mortality rates. CONCLUSIONS: Our findings, based on a national registry, support the high mortality and poor outcome of anticoagulant related ICH.
