- Abstract
- Background
Treatment with heparin has been an area of great controversy among neurologists. The goal of this study was to compare the actual usage patterns of intravenous heparin according to the stroke subtype, location, severity of the stroke, different hospitals, and various departments.
Methods
The records of 1204 patients with acute ischemic stroke admitted to 10 teaching hospitals between January 2000 and December 2000 were reviewed. The patients were divided into two groups of whether or not they were given intravenous heparin. Cases of acute ischemic stroke were subdivided according to the TOAST classification. Patients with NIH Stroke Scale scores were categorized as having mild, moderate, and severe stroke. Terminal hospital stays were subdivided further by department: internal medicine, neurology, neurosurgery, rehabilitation medicine, and others.
Results
512 patients (42.5%) were treated with heparin. The usage of heparin in the case of large artery atherosclerosis occupied 46%, small vessel occlusion 31 percent, cardioembolism 73%, other determined etiology 33%, and undetermined etiology 46%. Heparin was used to treat 46% of the patients with a lesion of anterior circulation, 49% of posterior circulation, and 38% of both anterior and posterior circulation. Heparin was more frequently used for moderate and severe strokes compared to mild strokes.
Conclusions
The utilization of intravenous heparin was more frequent in treatment of the cardioembolism subtype and moderate-to-severe strokes. Practice variation according to the hospitals and discharge departments were manifested.KeyWords:Cerebral infarctions, Heparin sodium
