Abstract

The inhabitants and lifestyles in eastern Taiwan are different from most of other areas, which may need unique interpretation. This retrospective hospital-based study is a pilot studies to analysis the risk factors, hemorrhage patterns and the related outcome in this area. From June 1996 through April 1998, 292 cases of spontaneous intracerebral hemorrhage (SICH) were enrolled in this study. Patient selection was made according to International Classification of Diseases, 9th Revision (ICD-9) for cerebrovascular disase. Clinical profiles, risk factors, hemorrhage patterns and associated outcomes were evaluated and accessed statistically. Of the 292 patients with SICH identified at Tzu-Chi Hospital during our study, the male to female ratio was 1.96. The peak incidence occurred in the age group of 55-64 year. According to the Glasgow Outcome Scale: 33.9% of the patients died, 6.5% were in a vegetative state, and only 25.7% had good outcomes. The risk factors included, 77.5% (N=224) of patients with SICH had hypertension, followed by diabetes (18.5%), previous stroke (17.1%), hyperlipidemia (7.8%) and cardiovascular disease (6.9%). Statistically significant poor outcomes were found in patients with systolic blood pressure less than 100 mmHg but higher than 200 mmHg (p=0.028), and in patients with high blood sugar levels at admission (p=0.0001). The majority of the hemorrhages were putamen (37.5%), followed by thalamus, subcortex, and hemorrhage with intraventricular extension. Good outcomes of statistical significance were found in patients with subcortical hemorrhages (p=0.019). In those with thalamic hemorrhages, the patients with right side lesion also had good outcomes of statistical significance (p=0.009). The patients with brainstem hemorrhages had the poorest outcomes (p=0.01). In eastern Taiwan, the major risk factors associated with SICH were hypertension, diabetes and previous stroke. These findings are similar to the results of other studies in other districts and countries. The prognosis for these patients was poor despite the advances in modern medical and surgical treatment.
