Background: For acute ischemic stroke (AIS) patients with history of prior stroke (PS) and diabetes mellitus (DM), intravenous recombinant tissue plasminogen activator (IV-tPA) therapy in the 3- to 4.5-hour window is off-label in Korea. This study aimed to assess the safety and efficacy of IV-tPA in these patients. Methods: Using data from a prospective multicenter stroke registry between January 2009 and March 2021, we identified AIS patients who received IV-tPA in the 3- to 4.5-hour window, and compared the outcomes of symptomatic intracranial hemorrhage (SICH), 3-month mortality, 3-month modified Rankin Scale (mRS) score 0-1 and 3-month mRS distribution between patients with both PS and DM (PS/DM, n=56) versus those with neither PS nor DM, or with only one (non-PS/DM, n=927). Results: The PS/DM group versus the non-PS/DM group was more likely to have a prior disability, hypertension, hyperlipidemia, coronary heart disease and less likely to have atrial fibrillation. The PS/DM and the non-PS/DM groups had comparable rates of SICH (0% vs. 1.7%; p>0.999) and 3-month mortality (10.7% vs. 10.2%; p=0.9112). The rate of 3-month mRS 0-1 was non-significantly lower in the PS/DM group than in the non-PS/DM group (30.4% vs. 40.7%; adjusted odds ratio [95% confidence interval], 0.81 [0.41-1.59]). Conclusions In the 3- to 4.5-hour window, AIS patients with PS/DM, as compared to those with non-PS/DM, might benefit less from IV-tPA. However, given the similar risks of SICH and mortality, IV-tPA in the late time window could be considered in patients with both PS and DM.

PURPOSE: Angiotensin converting enzyme inhibitor (ACEI) and angiotensin receptor blocker (ARB) are associated with a decreased incidence of new-onset diabetes mellitus (NODM). The aim of this study was to compare the protective effect of ACEI versus ARBs on NODM in an Asian population. MATERIALS AND METHODS: We investigated a total of 2817 patients who did not have diabetes mellitus from January 2004 to September 2009. To adjust for potential confounders, a propensity score matched (PSM) analysis was performed using a logistic regression model. The primary end-point was the cumulative incidence of NODM, which was defined as having a fasting blood glucose > or =126 mg/dL or HbA1c > or =6.5%. Multivariable cox-regression analysis was performed to determine the impact of ACEI versus ARB on the incidence of NODM. RESULTS: Mean follow-up duration was 1839+/-1019 days in all groups before baseline adjustment and 1864+/-1034 days in the PSM group. After PSM (C-statistics=0.731), a total 1024 patients (ACEI group, n=512 and ARB group, n=512) were enrolled for analysis and baseline characteristics were well balanced. After PSM, the cumulative incidence of NODM at 3 years was lower in the ACEI group than the ARB group (2.1% vs. 5.0%, p=0.012). In multivariate analysis, ACEI vs. ARB was an independent predictor of the lower incidence for NODM (odd ratio 0.37, confidence interval 0.17-0.79, p=0.010). CONCLUSION: In the present study, compared with ARB, chronic ACEI administration appeared to be associated with a lower incidence of NODM in a series of Asian cardiovascular patients.

A ruptured aneurysm of the pancreaticoduodenal arteries is an emergency condition, with a high mortality rate. Therefore, early diagnosis and adequate management are needed. Recently, treatment with a transcatheter arterial embolization has decreased the mortality rate. A 68-year-old man presented with persistent abdominal pain and dyspnea. Contrast abdominal computed tomography revealed a large retroperitoneal hematoma, with an actively bleeding focus. An urgent celiac and superior pancreaticoduodenal arteriogram showed a contrast extravasation, about 15 X 8 mm in size, with a saccular aneurysm of the distal anterior superior pancreaticoduodenal artery; therefore transcatheter arterial embolization was performed. The patient's condition improved without complication after the embolization.

BACKGROUND: Non-traditional risk factors of cardiovascular disease such as endothelial dysfunction, inflammation and malnutrition may be significant contributors to the excessive cardiovascular mortality in end stage renal disease (ESRD) patients. This study was undertaken to evaluate endothelial function in diabetic ESRD patients on hemodialysis and correlation between endothelial dysfunction and clinical, biochemical parameters. METHODS: Twenty eight stable diabetic ESRD patients (M: F=1.3: 1, average age: 60.1+/-1.0 yr) on hemodialysis were included. flow-mediated dilation (FMD) of brachial artery was measured using Doppler ultrasonography with 10 MHz transducer. Subjective global assessment (SGA) was used to assess the nutritional status of patients. RESULTS: The FMD (%) (% change of brachial artery diameter between before and after cuff inflation) was 5.1+/-1.0%. Serum albumin and C-reactive protein (CRP) were independent factors influencing SGA. When the patients were divided into groups according to history of ischemic heart disease (IHD), systolic pressure was significantly higher and FMD (%) was significantly lower in the group of patients with IHD compared with the group of patients without IHD. The FMD (%) showed significant positive correlation with SGA, serum albumin, and significant negative correlation with CRP. On multiple regression analysis, however, only CRP was an independent factor affecting FMD (%). CONCLUSION: These findings suggest that CRP influenced the nutritional status of diabetic ESRD patients on hemodialysis, and endothelial dysfunction, estimated by FMD, was significantly correlated with CRP. Therefore, CRP can be a modifiable risk factor for endothelial dysfunction in diabetic ESRD patients on hemodialysis.

An indirect porcine epidemic diarrhea (PED) virus (PEDV) enzyme-linked immunosorbent assay (ELISA) was compared with the serum neutralization (SN) test by testing 46 samples from experimentally infected sows, 73 samples from naive sows, and 1, 024 field sow samples from 48 commercial swine farms of undefined PED status. The SN test and the ELISA were performed using PEDV, KPEDV-9 strain. Viral proteins as a coating antigen of PEDV ELISA were extracted from the cytoplasm of PEDV-infected Vero cells using a non-ionic detergent, Triton X-100, and a simple protocol of PEDV ELISA was followed. The presence of antibodies in these experimental samples was confirmed by SN and ELISA in which the sensitivity of the ELISA was 89.1%, and the corresponding specificity was 94.5%. On testing 1, 024 field samples, an overall agreement of 84.2% was generated between the SN and ELISA. This study demonstrates that the PEDV ELISA is a useful serodiagnostic screening test at herd level for detecting swine antibodies against PEDV.

BACKGROUND AND OBJECTIVES: "Recovery only" ST-segment depressions are sometimes detected during an exercise treadmill test. We undertook this study in order to clarify the predictive value of exercise-induced ST-segment depression occurring in recovery only. SUBJECTS AND METHODS: The study included 931 patients who had both a sign or symptom -limited treadmill test. Of the 66 patients who demonstrated abnormal ST-segment responses, 43 experienced ST-segment depressions during exercise (Group A) and 23 displayed such responses only during recovery (Group B). RESULTS: The positive predictive value of an exercise treadmill test for significant angiographic disease in group A (81.3%) was statistically different from the predictive value in group B (30.4%). Horizontal ST-segment depression in recovery periods and female sex were statistically significant factors favoring negative coronary angiographic results. CONCLUSION: The occurrence of horizontal mild ST-segment depression during only the recovery periodgenerally represents a "false positive" response, particularly in female patients.

BACKGROUNDS AND OBJECTIVES: C-Reactive protein (CRP) levels are powerful predictors of cardiac complications and death in patients with unstable angina unrelated with myocardial cell damage or myocardial ischemia. This study was performed to determine the optimal timing to measure CRP to predict cardiac events in patients with unstable angina. MATERIALS AND METHOD: The study was comprised 50 patients with unstable angina (Braunwald Class IIIb). We randomized the study subjects by the time of CRP elevation (> 8mg/L): Group A (on admission, 15 patients), Group B (during hospitalization, 19 patients), and Group C (at discharge, 19 patients). RESULTS: 1) CRP levels (median and range) of Group A, B, and C were 10.6 (8.2-24.2), 12.8 (8.1-33.7), and 10.3 (8.1-18.7) mg/L, respectively (p=S). 2) During clinical follow-up at a mean duration of 12 months, there were 1 death, 1 myocardial infarction, 6 revascularization therapy (PTCA or CABG) and 11 recurrent angina. 3) In Group A, 10 cardiac events (1 myocardial infarction, 4 revascularization therapy, and 5 recurrent angina) occurred. The elevated levels of CRP predicted cardiac events during clinical follow-up with sensitivity of 53%(10/19), positive predictive value of 67%(10/15), and negative predictive value of 74%(26/35). In Group C, 13 cardiac events were occurred. Sensitivity, positive and negative predictive value to predict cardiac events of elevated levels of CRP were 68%(13/19), 68%(13/19) and 81%(25/31), respectively. 4) Elevated levels of CRP (>8mg/L) were predictors for cardiac events in patients with unstable angina (Group A; p<0.05, Group B; p<0.05, Group C; p<0.001). However, by logistic regression analysis, CRP values > 8mg/L at discharge were only predictive of cardiac events with odd ratio of 6.01 (95% CI 1.50-44.3, p<0.05). CONCLUSIONS: CRP (> 8mg/L) was elevated in 38% of patients at discharge and elevated levels of CRP at discharge were only predictive of cardiac events in patients with unstable angina.

PURPOSE: The aim of this study was to assess the involvement of several organs patients with Marfan syndrome in Korea. Also the clinical features in childhood patients with Marfan syndrome were assessed. METHODS: Thirty-eight cases of Marfan syndrome were enrolled in this study. Clinical evaluations of the musculoskeletal, cardiovascular and occular system were performed in all cases. RESULTS: The musculoskeletal system was involved in 32 cases (84.2%) and occular system in 24 cases (63.1%). Cardiovascular abnormalities were found in 19 cases (50.0%) at initial evaluation. Family history was involved in 21 cases (55.2%). Ectopia lentis was found in 17 cases (70.8%). Severe myopia and iris abnormalities were also present in 14 cases (58.2%). The ascending aorta was dilated in 13 cases (34.2%). Emergency operation was performed in 3 cases (7.9%) because of a dissecting aorta. Mitral regurgitation and prolapse were found in 29 cases (76.4%) and other valve insufficiency was accompainied in 5 cases (13.1%). Of the 38 cases, 29 patients (79.3%) were less than 15 years of age and their major manifestations were occular problems in 23 cases (79.3%), and family history in 17 cases (58.6%). In one infant, severe heart failure was the predominant clinical feature. CONCLUSION: The clinical features of Korean patients with Marfan syndrome were summarized in this report. Heart failure was the main manifestaton in infantile Marfan syndrome. Early treatment with beta-blocker and valvular replacement can prevent fatality, i.e. aortic dissection, in this disease, concern and management should be advocated in the early detection of Marfan syndrome.
