Three hundreds an7 thirty-nine patients of cerebrovascular accidents were studied clinically during three years from October 1971 to September 1974 in the Department of Internal Medicine, Kyung Hee University Hospital.
The diagnostic criteria of cerebrovascular accidents was based on the Okinaka´s modification of Millikan´s classification.
1. Cerebrovascular accidents were found in12.7 % of total admissions of medical department.
2. Among 339 cases of cerebrovascular accidents, cerebral hemorrhage was presented in 54.28%, cerebral thrombosis in 23.59%, subarachnoid hemorrhage in 11.79%, cerebral embolism in 4.13%, transient cereberal ischemia in 4.42%, and hypertensive enceplialopathy in 1.79%.
3. The distribution of sex in cerebrovascular accidents disclosed that male was dominant with 59. 29% of patient, (the male to the female ratio was 1.46:1). The ratio between male and female was 1.35:1 in cerebral hemorrhage, 1.6 : 1 in cerebral thrombosis, and 1.5: 1 in subarachnoid hemorrhage.
4. The distribution of age in cerebrovascular accidents disclosed hat the sixth decade was most predominant, followed by the seventh and the fifth decade is turn.
5. The underlying diseases in cerebrovascular accidents were found in the majority of the patients and especially the hypertension was found in 20.22% of those with cerebral hemorrhage, in 85.0% of subarachnoid hemorrhage, in 66.25% of cerebral thrombosis, in 64.28% of cerebral embolism, in 60. 0% of transient cerebral ischemia, and in 100% of hypertensive encephalopathy.
6. The mortality rate in cerebrovascular accidents was 46.9%;64.48% in cerebral hemorrhage, 20.0% in cerebral thrombosis, 20.0% in subarachnoid hemorrhage, 57.14% in cerebral embolism, 16.67% in liypertensive encephalopathy, and no death in transient-cerebral ischemia. The duration from the onset of cerebrovascular accidents to death disclosed that 52.38% of thee patients died within 24 hours all of which were "With cerebral hemorrhage, and 7.15% died, after one week.
7. The fundoscopic findings in cerebrovascular accidents by Keith-Wagner classification disclosed that grade II were found in 42.31%, grade III in 25.21%, and grade I in 16.24% in turn.
The electrocardiographic findings were abnormal in 87%; left ventricular hypertrophy was found most frequently in 78.74% among the abnormal ECG, and atrial fibrillation was found in 92.86% of cerebral embolism.
The findings of cerebrospinal fluid disclosed that bloody CSF was found in 48.44% which was associated with cerebral hemorrhage or subarachnoid hemorrhage. In cerebral hemorrhage, 70.4% was bloody, 19.2% was xanthochromic and only 10.4% was clear, whereas 95.92% was clear in cerebral thrombosis.
