BACKGROUND: We performed this study to evaluate the long-term clinical prognosis, the effects of anti-anginal medicines on angina, and the factors on recurrence of angina in patients with angina and insignificant coronary artery stenosis (CAS). METHODS: The study population was consisted of 372 patients with angina and normal or minimal (less than 50 % stenosed) CAS out of 2475 consecutive patients who were performed coronary angiogram for 3.5 years. We reviewed the medical record of the study population. RESULTS: Myocardial infarction was developed in 2 cases (0.5%), recurrence of angina 59 cases (16%), and no death during mean 19 months follow-up period out of 372 patients. Patients with normal coronary artery (n=66) were younger (mean 54 yrs vs 59 yrs, p<0.001), had less incidence of diabetes (5% vs 13%, p<0.01), hypertension (19% vs 29%, p<0.05), recurrent angina (15% vs 18%, not significant), and myocardial infarction (0.4% vs 0.9%, not significant) than patients with minimal lesion (n=06). Anti-anginal medicine did not show benefits in relieving recurrent angina. Furthermore, in case of taking nitrates in patients with normal coronary artery, there was more frequent recurrence of angina (23% vs 13%, p<0.01) than not taking nitrates. There were no affecting factors to the recurrent angina among age, sex, ischemic changes on electrocardiogram, smoking, hypertension, diabetes, and hyperlipidemia. CONCLUSION: The long-term clinical outcomes in patients with insignificant CAS were good. Although there were no definite factors for recurrence of chest pain, administration of nitrates may cause more frequent angina in patients with normal coronary angiography.

BACKGROUND AND OBJECTIVES: Ablation of the slow pathway in patients with atrioventricular nodal reentrant tachycardia (AVNRT) can be performed by using a specific intracardiac electrogram findings predicting a successful radiofrequency catheter ablation. The purpose of the present study is to recognize a specific intracardiac electrogram findings predicting a successful sites of radiofrequency catheter ablation in patients with AVNRT. MATERIALS AND METHODS: The study population consisted of the 18 patients (7 males, mean age:46 yr) to undergo successful catheter ablation using radiofrequency current in order to eliminate AVNRT from January 1993 to september 1994. We have analyzed local intracardiac electrogram at successful and unsuccessful sites of radiofrequency catheter ablation before the radiofrequency application: Atrial electrogram amplitude, duration, number of peaks in atrial electrogram, atrial/ventricular (A/V) electrogram amplitude ratio, and presence of His potential and/or slow potential. RESULTS: Of 18 patients, 16 patients underwent a slow pathway ablation, the other 2 patients a fast pathway ablation. The mean A/V electrogram amplitude ratio at successful and unsuccessful sites was 0.69+/-0.91 and 1.86+/-2.03, respectively. The mean atrial electrogram duration and number of peaks at successful and unsuccessful sites was 57+/-16 msec vs 69+/-16 msec and 1.7+/-0.5 vs 2.2+/-0.7, respectively. His bundle electrogram was seen in one slow pathway ablated and one fast pathway ablated patient. No slow potential could be identified in any of these 18 patients. CONCLUSION: We think that A/V electrocardiogram amplitude ratio below 0.5 at posterior interatrial septum along tricuspid annulus is important marker indicating a successful ablation sites.

PURPOSE: The admission rates for pediatric asthma are increasing annually and are partially responsible for the increased rates of readmission. Selections of children with a high-risk of readmission and aggressive treatments of them may improve treatment outcome and cost- effectiveness. The purpose of this study is to evaluate the risk factors affecting readmission in cases of bronchial asthma in children. METHODS: We reviewed the medical records of 95 cases under 14 years of age who were admitted to the Department of Pediatrics, Kyung-Hee University, from March 1996 to February 1997 and divided them into readmission and first admission group. RESULTS: Readmission cases were 52 (55%). Age, sex, duration of admission, duration of oxygen therapy, serum IgE concentration, duration of symptoms prior to admission and severity of asthma were not statistically significant compared with those of the control group (t-test) (P>0.05). Use of prophylactic agents, family history of allergic diseases and past history of bronchiolitis were significant (P<0.05), but age under 4 years and sex were not significant (X2-test). Age under 4 years, history of bronchiolitis, and history of previous hospital admission for asthma were significant (P<0.05), but sex, severity of asthma, history of frequent upper respiratory tract infection, family history, and the use of prophylactic agents were not statistically significant (P>0.05) as independent risk factors. CONCLUSION: Age under 4 years, past history of bronchiolitis, and history of previous hospital admission for asthma were significant risk factors for hospital readmission. Further study needs to be done to decrease the readmission rates.

BACKGROUND: Patients with sinus rhythm, the left atrial appendage(LAA) appeared as a vigorously contracting structure and the blood flow patterns of LAA showed biphasic configuration. However, patients with AF rhythm the blood flow showed irregular or no configuration in doppler echocardiographic study. The purpose of this study is to evaluate relationship between the blood flow patterns of LAA with the presence of spontaneous contrast(SC) and thrombi in LAA. METHODS: We performed TEE and TTE simultaneously to 58 consecutive patients who had native mitral valve disease or mitral prosthesis. Spontaneous contrast(SC) and the presence and location of LAA thrombi were evaluated during TEE and left atrial dimension(LAD) & ejection fraction(EF) were evaluated during TTE. We divided the whole subjects into three groups according to the blood flow patterns ; regular pattern(Group 1), irregular pattern(Group 2), no flow pattern(Group 3). RESULTS: 1) Blood flow within the left atrial appendage is divided with three groups among of them, atrial fibrillation have two blood flow patterns. 2) Peak prositive & negative flow velocity within LAA in AF rhythm groups were slower than normal sinus rhythm group.(p<0.01) 3) Left atrial dimension in group 3 is significantly larger than others groups.(p<0.01) 4) Spontaneous contrast(SC) with LAA could be detected in 2(6.8%) of the 29 patients of group 1, 6(31.5%) of the 19 patients of group 2, 10(100%) of the 10 patients of group 3. Incidence of SC within LAA in group 3 is significantly higher than others groups. 5) LAA thrombi could be detected in 1(3.4%) of the 29 patients of group 1, 1(5.2%) of the 19 patients of group 2, 3(30%) of the 10 patients of group 3. Incidence of LAA thrombi is significangly higher than other groups. CONCLUSIONS: We can suggest that blood flow within LAA is divided into three groups according to the blood flow patterns, and spontaneous contrast and thrombi in LAA were closely related with the blood flow pattern.
