Abstract:
Objective To investigate the therapeutic effect of low-dose low-molecular-weight heparin (LMWH) anticoagulation therapy in acute phase by prospective observational study and analyze clinical data of patients with asymptomatic hemorrhage transformation after acute ischemic stroke with non-valve atrial fibrillation.
Methods The clinical data of 120 patients with asymptomatic hemorrhage transformation after acute ischemic stroke with non-valve atrial fibrillation hospitalized in Neurology of the People's Hospital of Rugao from January 2016 to November 2018 were selected. According to whether the patients with hemorrhagic cerebral infarction were treated with LMWH, they were divided into two groups:anticoagulation group (n=56) and control group (n=64). All patients were followed up for 30 days, with National Institutes of Health Stroke Scale (NIHSS) reduction score, 30 days modified Rankin (mRs) score, 30 days good prognosis (mRs ≤ 2), recurrentcerebral infarction, other embolic events, intracranial/extracranial hemorrhage events as the main observation indexs.
Results The main observation indexes of anticoagulant group and control group were compared:NIHSS reduction score, recurrentcerebral infarction (1.79% vs 14.06%) were statistically significantly different (P < 0.05).There were no significant difference in 30 days mRs score, 30 days good prognosis, intracranial/extracranial hemorrhage events and other embolization events.Single factor (anticoagulant therapy) analysis showed NIHSS reduction score (OR=2.41, 95%CI 1.30-3.51), recurrentcerebral infarction (OR=0.10, 95%CI 0.01-0.79) were statistically significant (P < 0.05), and multi-factor analysis showed that NIHSS reduction score (OR=39.87, 95%CI 21.98-57.77) and recerebral infarction (OR=0.10, 95%CI 0.01-0.86) were statistically significant (P < 0.05).
Conclusions LMWH anticoagulant therapy in the acute phase of asymptomatic hemorrhagic transformation after acute ischemic stroke with non-valve atrial fibrillation can improve neurological function, reduce the risk of recurrentcerebral infarction, and not increase the incidence of intracranial/extracranial bleeding events.
