■ Objectives The purpose of this study was to investigate the correlation of The Korean Standard Pattern Identification for Stroke and Intima-Media Thickness of common carotid artery(CCA-IMT). ■ Methods 100 subjects with acute ischemic stroke were recruited from the patients admitted to DongEui Medical Center from the June 2011 to January 2014. We assessed 100 patient's Common Carotid Intima Media Thickness data by B Mode ultrasonography. We investigated pattern identification of all subjects based on Korean Standard Pattern Identification for Stroke-III. then, We analyzed their characteristics, risk factor, blood test result, life style. ■ Results We analyzed indicators of Korean Standard Pattern Identification for Stroke-III by Common Carotid Intima Media Thickness difference. As a result, pale complexion, look powerless, drowsiness like to lie, heat vexation and aversion to heat were significantly higher in the CCAIMT ≧ 1.0mm group then in the CCA-IMT < 1.0mm group. ■ Conclusion According to the analysis, the Relationship between Carotid Intima-Media Thickness and The Korean Standard Pattern Identification for Stroke in Ischemic Stroke Patients were founded. To acquire more concrete conclusion on this theme, we need more research.

Objective : Despite improvement of therapeutic regimen, incidence of stroke increases and it remains a leading cause of death. Our study aims at offering variable data on recurrent strokes. Methods : There were 59 patients who admitted from Jan. 2002 to Dec. 2004 due to recurrent strokes. A retrospective longitudinal cohort study was done. Results : Four-hundred-seventy five patients, diagnosed with acute stroke, experienced 491 strokes in 3 years, and there were 75 recurrent strokes [15.3%] in 59 patients. These 59 patients were included in the study. First hemorrhagic cases [H] were 19 [32%], and the first infarction cases [I] were 40 [68%]. Subsequent strokes after first stroke were as follows : $H{\to}H$ 14 [23.7%] cases, $H{\to}I$ 5 [8.5%], $I{\to}H$ 8 [13.6%], $I{\to}I$ 32 (54.2%]. A Cox regression analyses showed that the first type of stroke was a significant factor to the second stroke as follows : if one has had a hemorrhagic stroke, the possibility of second hemorrhagic attack ($H{\to}H$ attack) increase 3.2 times than ischemic type and in ischemic stroke [$I{\to}I$ attack] 3.6 times increased incidence of second ischemic attack. Conclusion : The recurrence rate of stroke was 12.4% [59 of 475 patients]. If the first stroke is hemorrhage or infarction, the next stroke would have high potentiality of hemorrhage, or infarction. The possibility of same type in second stroke Increase over 3 times. In $H{\to}H$ group, the time interval between first and second stroke was shorter and the age of onset was earlier than in $I{\to}I$ group. Moreover, the infarction was more frequent than hemorrhage in multiple strokes. There was a correlation in lacunar type infarction between first and second attack.

Objective : To evaluate the efficacy of balloon guiding catheter (BGC) during thrombectomy in anterior circulation ischemic stroke. Methods : Sixty-two patients with acute anterior circulation ischemic stroke were treated with thrombectomy using a Solitaire stent from 2011 to 2016. Patients were divided into the BGC group (n=24, 39%) and the non-BGC group (n=38, 61%). The number of retrievals, procedure time, thrombolysis in cerebral infarction (TICI) grade, presence of distal emboli, and clinical outcomes at 3 months were evaluated. Results : Successful recanalization was more frequent in BGC than in non-BGC (83% vs. 66%, p=0.13). Distal emboli occurred less in BGC than in non-BGC (23.1% vs. 57.1%, p=0.02). Good clinical outcome was more frequent in BGC than in non-BGC (50% vs. 16%, p=0.03). The multivariate analysis showed that use of BGC was the only independent predictor of good clinical outcome (odds ratio, 5.19 : 95% confidence interval, 1.07-25.11). More patients in BGC were successfully recanalized in internal carotid artery (ICA) occlusion with small retrieval numbers (<3) than those in non-BGC (70% vs. 24%, p=0.005). In successfully recanalized ICA occlusion, distal emboli did not occur in BGC, whereas nine patients had distal emboli in non-BGC (0% vs. 75%, p=0.001) and good clinical outcome was superior in BGC than in non-BGC (55.6% vs. 8.3%, p=0.01). Conclusion : A BGC significantly reduces the number of retrievals and the occurrence of distal emboli, thereby resulting in better clinical outcomes in patients with anterior circulation ischemic stroke, particularly with ICA occlusion.

Purpose: This study aimed to examine influence of cognitive function, disease severity and disability on ability to perform activity of daily living (ADL) after ischemic stroke. Methods: A total of 88 patients with ischemic stroke were recruited from January 1, 2008 to December 31, 2012 and assessed with the standardized cognitive test battery and self-reports about disease severity, disability, and ADL. To analyze the data, ANOVA, Pearson correlation coefficients and multiple regression were conducted using SPSS/WIN program. Results: Significant correlations were found between ADL and visuospatial function, visual memory, executive function, and disability (r=.29~.38). Executive function and disability explained 17.3% of total variability in ADL performance after ischemic stroke. Conclusion: Executive function may be a promising target for cognitive rehabilitation after ischemic stroke. Thus, effective therapeutic interventions such as cognitive training for stroke patients should be considered to improve their ability to perform ADL.

Objectives: This study aimed to investigate the seasonal variation in stroke types, ischemic stroke subtypes, stroke risk factors and Sasang constitutions. Methods: 226 patients with acute stroke within 14 days onset were included, who were admitted to Kyunghee Oriental Medical Center from November 2005 to October 2006. The year was subdivided into four parts: spring (March-May); summer (June-August); fall (September-November); and winter (December-February). Stroke types, ischemic stroke subtypes, stroke risk factors and Sasang constitutions in the four groups were examined. Results: Ischemic stroke was most frequent in summer, whereas hemorrhagic stroke was most frequent in winter. There was no significant difference in seasonal variation of stroke. The frequency of ischemic heart disease among stroke risk factors was significantly high in spring (p=0.031). The frequency of hypertension, diabetes mellitus, atrial fibrillation, and hyperlipidemia did not differ among seasons. There was no significant difference in Sasang constitution among seasons. Frequency of small vessel occlusion was highest in summer. Large artery atherosclerosis was frequent in spring and summer,but seasonal variation of ischemic stroke subtypes did not show statistical difference. Conclusion: Acute stroke demonstrates seasonal characteristics according to stroke types, ischemic stroke subtypes, risk factors for stroke, and Sasang constitutions. These results have important clinical implications in stroke prevention.

Background and Purpose: To evaluate the blood flow velocity using doppler ultrasound of the carotid artery, vertebral artery, and basilar artery in stroke patients Material and Methods: To evaluate the blood flow, I measured the peak systolic velocity and mean velocity of the common carotid artery(CCA), internal carotid artery(ICA), external carotid artery (ECA). vertebral artery(VA), and basilar artery(BA) in 44 stroke patients and 15 healthy adults. To investigate the difference between ischemic stroke patients and normal healthy adults, I selected 44 ischemic stroke patients diagnosed by brain CT and brain MRI, and 15 healthy adults who did not have any symptoms of stroke, hypertension, heart disease, and diabetes melitus. Results: Peak velocity in normal adults was 50.6${\pm}$1.6cm/sec in the CCA, 67.2${\pm}$1.7cm/sec in the ICA, 62.5${\pm}$2.4cm/see in the ECA, 45.5${\pm}$1.9cm/sec VA. and 50.5${\pm}$3.5cm/sec in the BA. Mean velocity in normal adults was 26.9${\pm}$1.1cm/sec in the CCA, 43.7${\pm}$1.4cm/sec in the ICA, 26.7${\pm}$1.3cm/sec in the ECA. 31.6${\pm}$1.9cm/sec in the VA and 33.0${\pm}$2.6cm/sec in the BA. In this study, there was a significant increase in the velocity of ICA, ECA, and VA of ischemic stroke patients in comparison with normal healthy adults. And the blood flow velocity of this study in the CCA and ECA was different from other reported foreign values and the other known values in my country. Conclusion: There was a significant difference in the blood flow velocity between ischemic stroke patients and normal healthy adults. And the blood flow velocity of this study was different from other reported foreign values and the other known values in my country. Therefore, it needs more detailed studies about old aged Korean and ischemic stroke patients than previous studies.

Purpose: This study aimed to develop a scale to measure distress in patients with ischemic stroke and verify its validity and reliability. Methods: Preliminary items were developed from literature review and in-depth interviews. The final preliminary scale was confirmed through a content validity test of eight experts and a preliminary survey of 10 stroke patients. The participants for psychometric testing were 305 stroke patients in the outpatient clinic. Validity and reliability analyses included item analysis, exploratory and confirmatory factor analysis, convergent validity, known-group validity, and internal consistency of the scale. Results: The final scale consisted of 17 items and 3 factors. The three distinct factors were 'self-deprecation, worry about future health, and withdrawal from society' and this structure was validated using a confirmatory factor analysis. Convergent validity was supported by comparison with the Center for Epidemiologic Studies Depression Scale (r = .54, p < .001) and Brief Illness Perception Questionnaire (r = .67, p < .001). Known-groups validity was verified by dividing groups according to 'duration since diagnosis' (t = 2.65, p = .009), 'presence of sequela' (t = 10.16, p < .001), and 'awareness of distress' (t = 12.09, p < .001). The internal consistency of the scale using Cronbach's α for the total items was .93. Conclusion: The Ischemic Stroke Distress Scale is a valid and reliable tool that reflects stroke distress effectively. It is expected to be used as a basic tool to develop various intervention strategies to reduce distress in ischemic stroke patients.

Objects : To gain better insights of East-west integrated treatment of ischemic stroke. We analyzed 89 patients with severe acute ischemic stroke who were admitted to the East-west integrated intensive care unit. Methods : Subjects enrollment was from the East-west integrated intensive care unit of Kyung Hee Medical Center from March 2006 to February 2007. Patients were admitted within 14 days after the onset of ischemic stroke. We assessed the subjects' general characteristics, risk factors, admitting routes and periods, diagnostic imaging, process of western treatment and Korean traditional treatment, complication and consequence. Results : The proportion of males was 50.6%, of females 49.4%, average age was male 66.0$\pm$10.3 and female 71.1$\pm$10.5. Average length of hospital stays was 19.5 days. Monthly admissions were highest in November and December. The admission route was through emergency room (61.8%) or ward (34.8%). Mean Glasgow coma scale score was 10.0$\pm$2.5, average time from symptom of onset to hospital admission was 2.3$\pm$2.2 days. Dominant ischemic vascular territory was middle cerebral artery (66.3%). Initial western treatment was argatroban (22.5%), urokinase (28.1%), and heparinization (38.2%). Distribution of Sasang constitution of So-yang to Tae-eum to So-eum was equal to 5.4 to 2.9 to 1.5. Major complications were observed in 40 (42.7%) patients. In hospital mortality was 12.4% (11 deaths), all of them caused by aggravation of neurological deficit and only 3 of them with major complications. There appears to be a significant positive relationship between length of hospital stay and occurrence of complications (P<0.05). After discharge from the ICU, 64 (71.9%) patients were improved, 11 (12.4%) patients had expired, and 14 (15.8%) patients were transferred. Conclusions : From this study, we suggest that patients with severe acute ischemic stroke should be treated with East-west integrated therapy for more favorable consequences and decreased mortality.

Objectives : The weekly variation of ischemic stroke incidence according to the age and sex. Methods : 977 consecutively admitted patients (521 males and 456 females) in a single stroke center from 2006 to 2008. All cases were confirmed with standardized criteria. We used the independent t-test and $x^2$ test in statistical methods. Results : The results demonstrated significant weekly variations of ischemic stroke incidence showing higher incidence on Saturday, Monday and Tuesday and lower incidence on the other days. Difference of ischemic stroke incidence was also shown between transit days, which included the transit days from the weekend to the week and vice versa, and non-transit days. Those aged older than 60 years and females showed more significant differences of weekly variation on transit days than on non-transit days. Conclusions : Ischemic stroke incidence has significant weekly variation, and transit days have higher incidence than non-transit days. Further study is required to identify the general weekly variation by multi-center trial.

Objectives : This study aimed to investigate the circadian variation in stroke types, ischemic stroke subtypes, and Sasang constitutions. Methods : 295 patients with acute stroke within 14 days onset were included, who were admitted to Kyunghee Oriental Medical Center from October 2005 to May 2007. The stroke onset time was subdivided into four groups of 6-hour intervals in a day. Stroke types, ischemic stroke subtypes, and Sasang constitutions in four groups were examined. Results : Most ischemic stroke occurred between 6:01-12:00 hours (30.2%). For ischemic stroke subtypes, the peak period of small-vessel occlusion was between 6:01-12:00 hours (33.2%), large-artery atherosclerosis was most common between 12:01-18:00 hours (39.5%), and cardiac embolism was most frequent between 18:01-24:00 hours (50%). In terms of Sasang constitution, Soyeumin and Taeyeumin were most common between 6:01-12:00 hours (36.4% versus 41.5%, respectively), but the peak time of Soyangin was between 12:01-18:00 hours (35.2%). Conclusion :Most ischemic stroke events occurred in the mid-to-late morning hours in the present study and there was a circadian variation of onset in ischemic stroke subtypes and Sasang constitution.
