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.

It has been believed that the increased release of free oxygen radicals(O2-, H2O2 and OH-) might be one of important factors in the pathogenesis of periodontal diseases. Polymorphonuclear leukocytes(PMNs) constitute the primary host resistance factor against infection. They are prominent cells in both the gingival tissue and gingival sulcus in most forms of periodontal disease. In response to invading microorganisms, the activated PMNs and macrophages generate free oxygen radicals, which play an important role in bacterial killing. The normal production of these free oxygen radicals is vital for the successful resistance of individuals to bacterial infection. However, the enhanced production of reactive oxygen species by accumulating PMNs may be detrimental to the host in certain disease states. This study was performed to evaluate the effect of Tetracycline-HCl(Tc-HCl) on generation of superoxide anion by PMNs. For the present study, 60ml of peripheral venous blood were obtained from systemically healthy subjects by venipuncture in median cubital vein and PMNs were separated by a one-step Ficoll-Hypaque gradient centrifugation method. PMNs were incubated with 1microgram/ml P.gingivalis strain A7436 LPS, 5% serum and Tc-HCl(5, 10, 50 and 100microgram/ml). The superoxide anion analysis was carried out by superoxide dismutase-inhibitable cytochrome C reduction method using Microplate autoreader(BIO-TEK(TM) Instrument Inc.). The difference of superoxide anion generation between control group and Tc-HCl group was statistically analyzed by paired t-test. The superoxide anion generation in the course of time after treatment with Tc-HCl was analyzed by ANOVA, and the superoxide anion generation in the course of time after treatment with various concentrations of Tc-HCl was analyzed by Repeated Measurement test. The results were as follows: 1. Superoxide anion generation by PMNs was significantly decreased by Tc-HCl(p<0.05). 2. There was no statistical significance in the inhibition of superoxide anion generation in the course of time after treatment with various concentrations of Tc-HCl(p>0.05). 3. Superoxide anion generation by PMNs was significantly decreased in the course of incubation time after treatment with Tc-HCl(p<0.05). The results demonstrate that the Tc-HCl inhibit superoxide anion generation by PMNs and the inhibitory effects depend on the exposure time rather than the concentration of Tc-HCl.
