BACKGROUND: Waist circumferences are widely used to diagnosis and assessment of obesity but various standards of the measuring waist circumference originate the confusion on diagnosis and assessment of obesity. According to this, this study is willing to light up standards of measuring waist circumference what is intimate with body mass index(BMI) and have a precision of intra observer and inter observers in repeated measurements of the waist. METHODS: Measuring of waist circumference by the 4 different standards(anterior superior iliac crest(ASIC), umbilicus, above 3 cm to ASIC, the thinnest area in the waist by the range of seeing) were performed on 102 people visiting Health Promotion Center of one medical collage hospital by two observers in each 2 times, total 16 times. Each data were analyzed by the relativity between the BMI and the each means of measuring waist circumference and by ANOVA test in intra observer and inter observer bias. RESULTS: The relation between BMI and data in measuring standard of ASIC of the waist circumference is the highest. (r=0.900) and the following umbilicus(r=0.896), above 3 cm to the anterior superior iliac crest(r=0.888), the thinnest area in the waist by the range of seeing(r=0.877), It is the lowest in intra observer bias that the thinnest area in the waist by the range of seeing, and ASIC in inter observer. CONCLUSION: It is desirable that ASIC is the standard of measuring waist circumference in the diagnosis of obesity and in measuring that by different two person, because of the highest relativity in BMI and the lowest inter observers bias. But the thinnest area in the waist by the range of seeing is desirable in measuring by same person because of intra observer bias.

PURPOSE: This study aims to investigate the effects of intervention using the therapeutic robot, PARO, on the cognition, emotion, problem behavior, and social interaction of elderly people with dementia. METHODS: A nonequivalent control group pretest-posttest design was used. A total of 33 elderly people with dementia living in a nursing home facility participated in the study, with 17 in the experimental group and 16 in the control group. The intervention program with PARO was administered twice a week for 6 weeks, for a total of 12 sessions. Data were collected before and after intervention, using a questionnaire, direct observation, and video recording. RESULTS: There were statistically significant differences in positive emotions and problem behaviors between the groups. The experimental group demonstrated a significant improvement in social interaction. CONCLUSION: PARO intervention can be utilized as an effective nursing intervention to increase positive emotions and social interaction, as well as decrease problem behaviors, in elderly people with dementia living in nursing home facilities.

BACKGROUND: Insulin resistance syndrome has been proposed as a major promotor of atherosclerotic disease and earlier studies have implied the hyperinsulinemia itself may enhance coronary vasomotor tone. In patients with vasospastic angina, previous studies have been inconclusive whether to basal coronary artery tone is elevated at the spasm related and nonspasm related artery. This study was performed to investigate whether basal coronary artery tone is elevated ans insulin resistance syndrome correlates to vasospastic angina. If insulin resistance syndrome correlates to vasospastic angina, we also investigated whether insulin resistance syndrome correlates to basal coronary artery tone. METHODS: The study comprised 27 patients with vasospastic angina(M/F ; 19/8, mean age ; 52+/-2 year) and 21 control subjects with atypical chest pain(M/F ; 9/8, mean age ; 47+/-3 year). We assessed basal coronary artery tone by obtaining the percent increase in coronary artery diameter induced by nitroglycerin and also examined glucose and insulin response to an oral glucose load of 75g. RESULTS: 1) There were no significant differences in body surface area, abdominal hip ratio, body mass index, incidence of hypertension, lipid profile, von-Willebrand factor, fibrinogen, and microalbumin except smorking incidence [vasospastic angia ; 16(50%) vs control ; 5(24%), p<0.05)] between vasospastic angina group and control. 2) Basal coronary artery tone was greater at the nonspastic site of the spasm-related artery(28.1+/-2.2% vs 13.1+/-0.9%, p<0.0001) and non-spasm related artery(23.7+/-1.6% vs 13.1+/-0.9, p<0.0001) in the patients with vasospstic angina than in control subjects. In the patients with vasospastic angina, high activity group had a greater basal coronary artery tone than low activity group at the nonspastic site of the spasm-related artery(31.7+/-2.6 vs 20.4+/-2.7%, p<0.001) and non-spasm related artery(26.8+/-2.0 vs 19.4+/-5.8%, p<0.001). 3) Plasma glucose and serum insulin response to an oral glucose load were similar between vasospastic angina group and control subjects, and glucose area, insulin area, and insulinogenic index(delta sigma Glucose / delta sigma Insulin)(330+/-12 vs 328+/-20 mg/dl *hour, 107+/-14 vs 96+/-17uU/ml*hour, and 2.18+/-0.33 vs 2.63+/-0.46, respectively, p=NS) also did not between both groups. 4) Two group did not differ siginificantly in the prportion of glucose intolerance but glucose area and insulin area were significantly high in vasospastic angina patients with glucose intolerance than in control subjects with normal glucose tolerance(366+/-22 vs 257+/-17mg /dl*hour, 127+/-19 vs 52+/-15uU*hour, respectively, p<0.05), but basal coronary artery tone did not differ significantly between vasospastic angina patients with glucose intolerance and control subjects with normal glucose tolerance. CONCLUSION: 1) These results revealed that basal coronary artery tone is elevated at the nonspastic site of the spasm related artery and non-spastic vessel, and the disease activity associated with elevated basal coronary artery tone in vasospastic angina. 2) But these results did not reveal the correlation of hyperinsulinemia with vasospastic angina, and so we did not determine the role of hyperinsulinemia as a pathogenesis of coronary spasm and the relation between hyperinsulinemia and basal coronary artery tone.

BACKGROUND: ATP is an endogenous nucleotide that has potential electrophysiologic effects. The effects of ATP are largely mediated by its metabolite, adenosine, which acts on A1 receptor in myocardium and mediates negative chronotropic, dromotropic, and inotropic action. The purpose of this study is to determine the efficacy and side effects of ATP in the treatment of paroxymal supraventricular tachycardia(PSVT). METHODS: We analyzed 28 episodes of PSVT in 22 patients(7 men and 15 women, mean age 467.+/-15.9 years), who were selected from Jan. 1992 to Sep. 1992. After measuring blood pressure and obtaining a standard 12 leads electrocardiogram(ECG), we rapidly injected ATP intravenously with dose of 10, 15, 20mg every 1 min, until the termination of PSVT. We recorded peri-injection and post-injection ECG, interval between ATP injection and the termination of PSVT, the pause after termination, side effects and blood pressure immediately after termination. RESULTS: 1) Among 28 episodes of PSVE, 26 episodes(92.9%) were terminated successfully : 21 episodes(75%) with 10mg, 3 episodes(10.7%) with 15mg, and 2 episodes(7.2%) with 20mg of ATP. 2 episodes(7.1%) were failed. 2) The PSVT ended 21.2+/-9.2 seconds after injection of ATP(maximally 40 seconds). 3) The mechanisms of PSVT in 9 patients were atrioventricular nodal reentrant tachycardia(AVNRT), those in 13 patients were atrioventricular reciprocating tachycardia(AVRT). 4) The side effects of ATP included 13 episodes of chest pain(46.6%), 9 episodes of ventricular arrhythmia(32.1%), 6 episodes of sinus pause(21.4%) and 5 episodes of atrioventricular block(17.9%), and these were uncomplicated and short-lasting. CONCLUSION: The ARP is a safe and effective therapy for the conversion of PSVT to sinus rhythm and perhaps more importantly, a valuable new approach to the management and diagnosis of wide-complex tachycardia.

BACKGROUND: During and immediately after percutaneous transluminal coronary angioplasty(PTCA), reversible ischemic electrocardiographic change and/of left ventricular dysfunction are developed. But it is not investigated whether there are potential myocardial cell damages following PTCA or not, and the clinical Significance of myocardial cell damage following PTCA. Recently cardiac Troponin-T has been developed as a new myocardial specific marker, especially myocardial damage. The object of this study is to investigate whether potential Myocardial damage following PTCA was occurred and the utility of cardiac Tropoin-T for predicting the complications during and immediately after PTCA. METHODS: The study group comprised 12 patients(M/F;8/4mean age;60 +/- 4year,AMI in 6) undergoing PTCA, Samples for Troponin-T were obtained before, directly after, after 2 hours, 6 hours, and after 12 hours and was determined by enzyme immunoassay on an ES 300 analyzer(Boehringer Mannheim). Discrimination limit for myocardial cell damage is 0.1 ng/ml in normal baseline level but if the baseline level is elevated such as acute myocardial infarction or unstable angina, myocardial cell damage is defined with further increase of cardiac Troponin-T(>0.1 ng/ml) compare to baseline level. RESULTS: 1) The mean duration of total balloon inflation is 10.7 +/- 2(3-22) minutes and the mean duration of single maximal inflation is 3.9 +/- 0.6(1-8) minutes. There are no significant change in concentration of Troponin-T by inflation time. None of the patients showed electroca rdiographic evidence for myocardial infarction. 2) Troponin-T were increased in 2 patients with unstable angina(0.01 vs 0.11 ng/ml) which were developed major dissection including acute closure during PTCA, and 2 patients with acute myocardial infarction(2.37 vs 3.73 ng/ml) which didn't developed dcomplication. The increase of cardiac Troponin-T were observed in 2 of 10 patients with uncomplicated PTCA(20%). 3)The subacute complications were not developed. CONCLUSION: The cardiac Troponin-T were increased significantly in two AMI patients with uncomplicated PTCA(2/10,20%). The increase of cardiac Troponin-T following PTCA is associated with periprocedural complications but the prognostic significance to detect postprocedural complication did not define in this study because there were no subacute complications after PTCA and may be limited value due to time course of complication(usaully within 1 hour after PTCA) and relatively long analytic time.

BACKGROUND: The endothelium is an important regulator of vascular tone via release of relaxing and constricting substances. The regulatory effect of the endothelium has been shown to be impaired in atherosclerotic arteries in human and animal models of hypertension. But there are some debates on extent and developing time of endothelium dysfunction in patients with hypertension, and the determining factors for endothelium dysfunction also were not defined. The objects of this study are to determine whether endothelial function is impaired in coronary and peripheral arteries, and to investigate the predicting factors for endothelial dysfunction in patients with essential hypertension. METHODS: The study patients comprised 14 patients with essential hypertension(M : 7, Mean age : 50+/-2 year) and 6 normal control (M :2, Mean age : 45+/-4 year). We assessed the vasomotor response to acetylcholine and nitroglycerin by change of arterial diameter during the infusion of acetylcholine, from 10(-9M) to 10(-6M) in coronary artery and 7.5, 15, and 25ug/min in left superficial femoral artery, and on intracoronary injection of 200ug nitroglycerin after acetylcholine infusion. RESULTS: 1) There were no significant differences in sex, age, body mass index and ventricular mass index, except systolic(174+/-5 vs 118+/-7mmHg, p<0.001) and distolic blood pressure(106+/-5 vs 75+/-5mmHg,p<0.001) between patients with hypertension and normal control. 2) There were no significant differences in laboratory date of total cholesterol, HDL-cho-lesterol, lipoprotein(a), microaluminuria and von-Willebrand Factor but Fibrinogen level was raised significantly in patients with hypertension than normal control(299+/-26 vs 192+/-23ng/dl, p=0.04). 3) The vasoconstrictor response to acetylcholine, 10-8 to 10-6 M concentration, at proximal, mid, and distal left anterior descending coronary artery were increased significantly in hypertensive patients than normal control(p<0.05). At rest superficial femoral artery, the vasodilator response to acetylcholine, only 25ug/min, was decreased in patients with hypertension(p<0.05). There was no signficant difference in the vasodilator response to nitroglycerin at coronary artery between two groups but in superficial femoral artery, the vasodilator response to nitroglycerin was decreased significantly in hypertensive patients(p<0.05). CONCLUSIONS: The results of this study suggest that endothelium dependent vascular relaxation is impaired in both coronary and superificial femoral artery and it remained to be investigated the predicting factors for endothelial dysfunction in patients with essential hypertension.

BACKGROUND: Unstable angina is a critical phase of ischemic heart disease, but there are no reliable noninvasive methods of assigning patients to different prognostic actegories. Recently cardiac Troponin-T has been developed as a new myocardial specific marker, especially myocardial injury. We investigated the value of the Troponin-T in unstable angina to determine whether the increase of cardiac Troponin-T might be a useful predictor of prognosis. METHODS: Unstable angina is defined as Braunwald classification(Class I, II, III). CLass I is new onset of severe angina or accelerated angina and no rest pain, class II is angina at rest but not within preceding 48 hour, and class III is angina at rest within 48 hour. We studied 16 cases of unstable angina(male:10, mean age:57+/-2year). We measured Troponin-T and CK-MB at admission, after 6 hours, and every 8 hour for 2 days. For the determination of serum Troponin-T, an enzyme immunosorbent assay (Boehringer Mannheim, ES 300 analyzer) was used. Above 0.1ng/ml was regarded as positive. During the admission, we investigated the myocardial infartion, sudden death, and the need of emergency PTCA and CABG. RESULTS: 1) Among 16 unstable angina patients, there are 12 patients in Class I(range 0.001-0.13, mean SD 0.04 0.01, median 0.02ng/ml) and 4 patients in Class III(range 0.03-1.56, mean SD 0.39 0.2, median 0.27ng/ml) and 4 patients showed positive value of Troponin-T. One was in Class I and the others were in Class III. 2) During the admission, one patient expired due to cardiogenic shock preceding inferior myocardial infarction, and 2 patients progressed non-Q wave myocardial infarction(NQMI). These 3 patients were in unstable angina Class III and had positive Troponin-T value. In Class I, one patient performed emergency CABG due to consistent chest pain at the sixth hospital day. These patient had negative Troponin-T value. 3) CK-MB increased in one patient with NQMI, and the other patients were not increased. CONCLUSION: Cardiac Troponin-T in serum appears to be a more sensitive indicator of myocardial cell injury than serum creatine Kinase MD activity, and its detection in the circulation may be a useful porgnostic indicator in patients with unstable angina.

BACKGROUND: The exercise stress testing(Treadmill Test) is one of the preferred noninvasive methods of identifying patients with coronary artery disease. ST-segment elevation during or immediately after exercise is uncommon and in most patients, it was associated with prior infarction, left ventricular hypertrophy or left bundle branch block, Exercise-induced ST-segment elevation has been attributed to ventricular wall motion abnormalities, and ischemia due to either coronary vasospasm or ervere proximal coronary stenosis. We examined the clinical, angiographic, and prognostic significance of 16 patients with exercise induced ST-segment elevation. METHODS: 16 patients with exercise-induced ST-segment elevation were retrospectively reviewed. The symptom-limited exercis testing was performedn using a modified Bruce protocol and in patients with acute myocardial infarction(AMI), low level exercise testing(Myocardial infarction protocol) was used. The significant ST-segment elecation was defined as a > or =1mm change present in >1 lead measured at 0.08 sec after J point and in > or =3 consecutive beats. Coronary arteriogram and percutaneous transluminal coronary angioplasty(PTCA) was performed using standard techniques within 7 days of initial exercise testing and a luminal diameter stenosis of >50% was considered significant. RESULTS: 1) We have studied 2076 exercise tests and 16 patients(M/F:15/1, Mean age : 58 years) developed exercise-induced ST-segment elevation. The initial diagnosis were acute myoca rdial infarction(AMI) in 12, variant angina in 2, effort angina in 1 and unstable angina in 1 patient. 9 of 12 patients with AMI were treated with thrombolytic agent(Urokinase 2.5 to 3 million unit) within 6 hours from the onset of chest pain. 2) Mean maximal ST-segment elevation was 2.6mm(range 1-5mm). The leads which showed exercise-induced ST-segment elevation were corresponded to the location of severe coronary stenosis in typical effort angina, to spasm site in variant angina, and to infarction site in AMI. 11 Patients had follow-up exercise testing and showed abolition of exercise-induced ST-segment elevation in 4 of 5 patients with AMI and 1 patient with effort angina after PTCA, and 1 patient with variant angina and 3 of 4 patient with AMI after medication. 3) In 12 patients, coronary angiography was performed, and showed 95% and 90% stenosis at proximal LAD in 2 patients with effort angina and >80% stenosis at proximal or mid lesion of infarct-related artery in 7 patients with AMI. In variant angina, one patient showed normal coronary artery and another patient showed 60% stenosis at mid LAD. On LV angiogram, there were moderate to severe hypokinesia instead of akinesia or dyskinesia at infarction site in all patients with AMI and showed normal LV contractility in patients with effort or variant angina. PTCA were successfully performed in 7 patients(effort angina 2, AMI 5). 4) The clinical follow up for 16 patients were obtained for mean follow-up duration of 17 months and during the clinical follow-up, 1 variant angina patient with mild stenosis at proximal LAD was died with ventricular fibrillation after discontinution of medication. There were CABG due to restenosis in 1 patient and cerebrovascular accident in 1 patient. CONCLUSION: 1) The exercise-induced ST-segment elevation signifies severe ischemia due to either severe proximal coronary stenosis or coronary arterial spasm. In AMI, this findings suggests the residual ischemia(or residual viable myocardium) in addition to left ventricular dyssynergy or aneurysm. 2) Adverse cardiac events can be provented by revascularization in patients who had critical coronary stenosis and by medical therapy in those with coronary vasospasm or mild coronary stenosis.
