Abstract PDF: We report on a rare case involving a 23-year-old female patient with mediastinal cystic mass complicated with acute pericarditis and cardiac tamponade. Pericardial fluid demonstrated lymphocyte-predominant exudate and the level of carcinoembryonic antigen (CEA) was unexpectedly elevated. Successive aspiration of mediastinal cystic mass revealed a very high level of CEA (>100,000 U/mL) and carbohydrate antigen 19-9 (>15,000 ng/mL). This patient was clinically diagnosed as an infected bronchogenic cyst complicated with pericarditis and cardiac tamponade. The treatment resulted in alleviation of her symptoms.

Abstract PDF: BACKGROUND
The occurrence of atrial fibrillation after ablation of atrial flutter is clinically important. We investigated variables predicting this evolution in ablated patients without a previous atrial fibrillation history. MATERIALS AND METHODS: Thirty-six patients (Male=28) who were diagnosed as atrial flutter without previous atrial fibrillation history were enrolled in this study. Group 1 (n=11) was defined as those who developed atrial fibrillation after atrial flutter ablation during 1 year follow-up. Group 2 (n=25) was defined as those who has not occurred atrial fibrillation during same follow-up term. Echocardiogram was performed to all patients. We measured left atrial size, left ventricle end diastolic and systolic dimension, ejection fraction and left atrial volume index before and after ablation of atrial flutter. The differences of each variables were compared and analyzed between two groups. RESULTS: The preablation left ventricular ejection fraction (preLVEF) and postablation left ventricular ejection fraction (postLVEF) are 54+/-14%, 56+/-13% in group 1 and 47+/-16%, 52+/-13% in group 2. The differences between each two groups are statistically insignificant (2.2+/-1.5 in group 1 vs 5.4+/-9.8 in group 2, p=0.53). The preablation left atrial size (preLA) and postablation left atrial size (postLA) are 40+/-4 mm, 41+/-4 mm in group1 and 44+/-8 mm, 41+/-4 mm in group 2. The atrial sizes of both groups were increased but, the differences of left atrial size between two groups before and after flutter ablation were statistically insignificant (0.6+/-0.9mm in group 1 vs -3.8+/-7.4 mm in group 2, p=0.149). The left atrial volume index before flutter ablation was significantly reduced in group 1 than group 2 (32+/-10 mm3/m2, 35+/-10 mm3/m2 in group 1 and 32+/-10 mm3/m2, 29+/-8 mm3/m2 in group 2, p<0.05). CONCLUSION: The difference between left atrial volume index before and after atrial flutter ablation is the robust predictor of occurrence of atrial fibrillation after atrial flutter ablation without previous atrial fibrillation.

Abstract PDF: BACKGROUND
P wave dispersion(PWD) is defined as the difference between the maximum and minimal P wave duration in any of the 12 leads of the surface ECG. The prolongation of atrial conduction time and the inhomogeneous propagation of sinus impulse are known electrophysiologic features in patients with paroxysmal atrial fibrillation(PAF). The purpose of this study was to determine the role of P wave dispersion for the prediction of PAF and to evaluate the effectiveness of prophylactic antiarrhythmic therapy. MATERIALS AND METHODS: The study population included 20 patients with a history of idiopathic PAF and 20 age and sex matched healthy control subjects. We measured the maximum P wave duration(P maximum) and P wave dispersion from 12 lead ECG. RESULTS: P maximum and P dispersion in idiopathic PAF were significantly higher than normal control group(97.2+/-12, 48.5+/-9msec vs, 76.5+/-11, 21+/-8msec, respectively p<0.001, <0.001). After 12-month follow up period P maximum and P dispersion were significantly reduced than those of initial state(77.2+/-13, 26.4+/-9msec vs. 97.2+/-12, 48.5+/-9msec, respectively p<0.001,<0.001). CONCLUSION: P dispersion and P maximum were significantly different between patients with idiopathic PAF and healthy control group. Those are easily accessible, non-invasive simple electrocadiographic markers that could be used for the prediction and prognostic factors of idiopathic PAF.

Abstract PDF: BACKGROUND
There are many evidences that inflammation is an important determinant of the development of atherosclerosis and one of the systemic markers of inflammation, C-reactive protein(CRP), is associated with extent of coronary artery disease and risk of coronary events. We assessed the time response of CRP response after coronary angioplasty and it's influence on the clinical restenosis in angina patients. MATERIALS AND METHODS: Patients included 36 angina patients undergoing single vessel angioplasty. Levels of CRP were measured before and 12, 24, 48, and 72 hours after angioplasty. Clinical restenosis was assessed at 6 months after procedure. RESULTS: Baseline CRP level was 0.30+/-0.01 mg/dL in stable and 0.46+/-0.28 mg/dL in unstable angina patients(p<0.05). After angioplasty, CRP level was increased with peak at 24 hour and persisted to 72 hours after angioplasty. At 24 hour after angioplasty, the magnitude of CRP change was 0.32+/-0.31 mg/dL in stable and 0.79+/-0.73 mg/dL in unstable angina patient(p<0.05). The change of CRP level was not associated with troponin-T after angioplasty. In unstable angina patients, clinical restenosis was developed in 8% of patients with low baseline CRP levels and in 50% of those with high baseline CRP levels more than 0.6 mg/dL(p<0.05). CONCLUSION: In unstable angina patients, inflammatory response is more increased than stable angina patients, and increased inflammatory response effects on the restenosis after coronary angioplasty.

Abstract PDF: BACKGROUND
Systemic embolism especially, cerebral infarction is one of the most important complications in patients with mitral stenosis. The authors analyse the some that could predict the development of cerebral infarction in cases of mitral stenosis and propose preventive therapeutic measures. METHODS: Retrospective study of 127 patients with rheumatic mitral stenosis was performed by analysis their medical records for transthoracic(TTE) or transesophageal echocardiography(TEE) over a 12months period. The patients were divided into two groups according to the presence (Group I: n=26, age: 55+/-13 years) or absence (Group II: n=101, age: 48.5+/-13 years) of cerebral infarction. No significant difference was observed between the two groups with respect to sex and functional class. RESULTS: Patients of group I were older (55.0+/-13 vs 48.5+/-13;p<0.05), had more dilated left atrial size(5.10+/-0.48 vs 4.81+/-0.70;p<0.05) and smaller mitral surface area(1.01+/-0.39 vs 1.21+/-0.45;p<0.05). In Group I, the incidence of atrial fibrillation(22 out of 26 vs 57 out of 101;p<0.05) and spontaneous left intra-atrial contrast phenomenon(22 out of 26 vs 44 out of 101;p<0.05) was more frequently observed. On multivariate analysis, atrial fibrillation and anticoagulant therapy were the independent predictive factors. CONCLUSION: Age, left atrial dilatation, the severity of mitral stenosis, the presence of spontaneous contrast and especially the presence of atrial fibrillation are the main predictive factors of the development of cerebral infarction in mitral stenosis. Patients presenting one or several of these factors may benefit from prophylactic anticoagulant treatment.

Abstract PDF: BACKGROUND
We sought to examine the use and outcomes with early intraaortic balloon couterpulsation(IABP) combined early reperfusion therapy in patients presenting with cardiogenic shock complicating acute myocardial infarction. The use of IABP in patients with cardiogenic shock is widely accepted. however, there is a paucity of information on the use of this technique in patients with cardiogenic shock who are treated with reperfusion therapy in Korea. MATERIALS AND METHODS: Twenty-eight Patients presented with cardiogenic shock were classified into two groups: the early IABP group (insertion within 12 hours after AMI onset time) and late IABP group (insertion after 12 hours). We compared In-hospital mortality in two group (early IABP group vs late IABP group). RESULTS: Two groups show no significant difference at clinical feature and coronary angiographic results. Among total 28 patients, 7 patients were treated with thrombolytic therapy and 21 patients with PTCA. Insertion site bleeding, fever, thrombocytopenia were reported as some of the complications of IABP insertion. In-hospital mortality of early IABP group and late IABP group were 4 patients(25%) and 8 patients(66%), respectively(p<0.05). Early IABP insertion and early PTCA showed lower hospital mortality rates. There was significant difference in the time to PTCA after AMI onset between the to groups(p<0.05). CONCLUSION: IABP appears to be useful in patients presenting with cardiogenic shock unresponsive medical therapy. Early IABP insertion and early Reperfusion therapy may reduce In-hospital mortality rates in PostMI Cardiogenic shock patients.

Abstract PDF: BACKGROUND
Left ventricular diastolic filling is an important determinant for maintenance of cardiac output during hemodialysis. Few investigators have studied the influence of hemodialysis on diastolic function. To evaluate the change of left ventricular systolic and diastolic function, we performed M-mode and Doppler echocardiopraphic studies before and after hemodialysis. METHODS: The study population consisted of 30 patients(15 patients were male, mean age 45+/-10 years) with CRF on maintenance henodialysis. They have normal left ventricular systolic function(Fractional shortening > 30%) and no evidence of valvular heart disease or regional wall motion abnormalities. The ejection fraction(EF) was measured using M-mode echocardiography and Doppler indices such as peak E velocity, peak A velocity, isovolumetric relaxaion time(IVRT), deceleration time(DT), and left ventricular ejection time(LVET) obtained from Doppler echocardiography. The index of myocardial performance(IMP) was calculated from each of the Doppler velocity indices. RESULTS: The weight reduction after hemodialysis was 2.1+/-1.0kg(p<0.0001). After hemodialysiss, there was some decrease in blood pressure(p<0.05), but no significant change in heart rate, EF and fractional shortening, mean VCF, peak A velocity, and DT. And significant in IVRT and IMP(p<0.05, p<0.0001) were noted. CONCLUSTION: In conclusion, preload reduction is the main mechanism that accounts for changes in Doppler diastolic indices after hemodialysis. And and increased IMP suggests that diastolic function may be aggravated after gemodialysis, and that implies impaired left ventricular filling and disturbed left ventricular compliance.

Abstract PDF: BACKGROUND
Patients with acute non-traumatic chest pain are among the most challenging patients for care by emergency physicians, so the correct diagnosis and triage of patients with chest pain in the emergency department(ED) becomes important. To avoid discharging patients with acute myocardial infarction(AMI) without medical care, most emergency physicians attempt to admit almost all patients with acute chest pain and order many laboratory tests for the patients. But in practice, many patients with non-cardiac pain can be discharged with simple tests and treatment. These patients occupy expensive intensive care beds, substantially increasing financial cost and time of stay at ED for the diagnosis and treatment of myocardial ischemia and AMI. Despite vigorous efforts to identify patients with ischemic heart disease, approximately 2% to 5% of patients presented to the ED with AMI and chest pain are inadvertently discharged. If the cause for the chest pain is known, rapid and accurate diagnosis can be implemented, preventing wastes in time and money and inadvertent discharge. Methods and Results: The medical records of 488 patients from Jan. 1 to Dec. 31, 1997 were reviewed. There were 320(angina pectoris 140, AMI 128) cases of cardiac diseases, and 168(atypical chest pain 56, pneumothorax 47) cases of non-cardiac diseases. The number of associated symptoms were 1.1+/-0.9 in non-cardiac diseases, 1.4+/-1.1 in cardiac diseases and 1.7+/-1.1 in AMI(p<0.05). In laboratory finding the sensitivity of electrocardiography(EKG) was 96.1%, while the sensitivity of myoglobin test ranked 45.1%. Admission rate was 71.6% in for cardiac diseases and 50.6% for non-cardiac diseases(p<0.01). Mortality rate was 8.8% in all cases, 13.8% in cardiac diseases, 0.6% in non-cardiac diseases, and 28.1% especially in AMI. CONCLUSION: In conclusion, all emergency physicians should have thorough knowledge of the clinical characteristics of the diseases which cause non-traumatic chest pain, because a patient with any of these life-threatening diseases would require immediate treatment. Detailed history on the patient should be taken and physical examination performed. Then, the most simple diagnostic approach should be used to make an early diagnosis and to provide treatment.

Abstract PDF: Imidapril(Tanatril(R)), a newly developed ACE inhibitor, has been used to treat hypertension and congestive heart failure. This study was designed to assess the antihypertensive effect and safety of Imidapril(Tanatril(R)) in patient with essential hypertension. 5-10mg of imidapril(Tanatril(R)) was administered once day in 30 patients with essential hypertension and followed up to 8 weeks. We tested the drug's effectiveness, safety, and the incidence of imidapril induced dry coughs. After 8 weeks of treatment with Imidapril, 76.2%(16/21) of patient showed lowered blood pressure and 47.6% showed normal blood pressure. The overall incidence of adverse effects was 33.3%(7/21). and among these adverse effects. dry cough was shown in only 9.5%. Thus, concluded that imidapril(Tanatril(R)) is as safe and effective as other ACE inhibitors. especially with imidapril showing very little incidence of dry cough compared to other ACE inhibitors.

Abstract PDF: There have been some case reports of the coexitence of extraadrenal pheochromocytoma and renal artery stenosis. Some reporters proposed that their coexistence may be associated through a common pathophysiological mechanism mediated by catecholamine secretion. Also some noted that trasient renal artery stenosis due to a spasm was induced by the catecholamines released from pheochromacytoma. We report a case of left paraaortic extraadrenal pheochromacytoma that had a transient oral captopril test positive result. After 5 days alpha-antagonist reduced the vasospastic response of catecholamines. After surgical removal of the tumor, plasma catecholamines and urinary vanillymandelic acid concentrations as well as the blood pressure level, were restored to normal.
