The athors have presented recently treated 4 cases of malignant tumors of the eye and adnexa. 1. All of them were rapidly aggrevated after previous incompleted surgical management (3 cases) or postponement 01 operation (1 case). 2. Three cases of them except adenoid cystic Ca. were recurred after orbital exenteration. 3. The authors were concluded that the poor prognosis is due to its nature of malignancy and delayed radical surgical management.

BACKGROUND AND OBJECTIVES: Acute coronary syndrome occurs most commonly in the setting of atherosclerotic coronary artery disease, but there is little information concerning the mechanism responsible for the transition from stable to unstable coronary atherosclerotic plaque. Hypothetically, several microorganism(Chlamydia pneumonia, Cytomegalovirus and Helicobacter pylori) and their inflammatory reaction have been suggested as a causative motive in progression of acute coronary syndrome. Although it is unclear whether the serum level of CRP as a inflammatory parameter is concerned with previous inflammatory change or myocardial necrosis, CRP apper to be predictive of higher risk for cardiac event in the patients with acute coronary syndrome. Our objective was to evaluate whether the inflammatory parameters(CRP, ESR and WBC count) is useful in predicting the short-term cardiac risk within 30 days. MATERIALS AND METHOD: One hundred and ten patients with acute coronary syndrome were enrolled from April 1998 through August 1998. Blood samples were collected at 1st hour, 24th hour, 48th hour and 7th day and tested for CRP, ESR, WBC count and CK-MB level. Values of 323 normal were used as control. All patients were followed up for 30 days and assessed for the presence of cardiac complications. RESULTS: Peak CRP value of the patients with acute myocardial infarction(3.4+/-3.85 mg/dL, n=2) was higher than that of the patients with unstable angina(0.7+/-0.93 mg/dL, n=8, p<0.05) and controls(0.3+/-0.48 mg/dL, n=23, p<0.05). Peak CRP value of patients with cardiac complication was higher than that of patients without complication(7.7+/-4.77 mg/dL, n=5 vs 1.3+/-1.74 mg/dL, n=5 ; p<0.05). In multivariate analysis, peak CRP value was the only predictive parameter for development of cardiac complications in the patients with acute coronary syndrome(Odds ratio 4.893, 95% confidence interval 1.212-19.756, p value=.026). In the high-CRP group(>2 mg/dL, n=0), the cardiac complication rate was higher than the low-CRP group(< or =2 mg/dL, n=0) (43.3% vs 2.5%, p<0.05). Peak CRP value was correlated with age(r=.191, p=.045), pulse rate(r=.186, p=.008), left ventricular ejection fraction(r=0.384, p<0.001), peak ESR(r=.383, p<0.001) and peak WBC count(r=.307, p=.001), but not with peak CK-MB level. CONCLUSION: Elevated CRP level in patients with acute coronary syndrome seems to be a valuable prognostic factor for the development of cardiac complications within 1 month after admission.

BACKGROUND AND OBJECTIVES: The angiographic profiles and myocardial ischemic variables were compared between patients with and without chest pain during exercise myocardial perfusion scintigraphy in patients with coronary artery stenoses. MATERIALS AND METHODS: Study population were 102 consecutive patients who have significant luminal stenoses (> 50%) on coronary angiography. They underwent symptom-limited treadmill exercise test and myocardial perfusion single photon emission computed tomography (SPECT). Tc-99m methoxylisobutyl isonitrile (MIBI) was injected intravenously at rest and one minute before the termination of exercise. Tomographic images were acquired within 1 hour of tracer injection. Electrocardiographic variables, scintigraphic summed reversibility scores and angiographic profiles were compared between patients with and without chest pain during exercise. RESULTS: Silent ischemia was noted in 52/102 (51%) of the subjects. The summed reversibility score of myocardial SPECT was not significanlty different between patients with (6.0+/-4.2) and without (5.1+/-5.0) chest pain. The extent, vessel distribution and stenosis severity of coronary artery disease were not significantly different between two groups. ST segment depression was more prominent in patients with chest pain (1.51+/-1.49 mm) than without chest pain (0.5+/-1.1 mm) during exercise stress testing. CONCLUSION: The degree of coronary stenoses and scintigraphic myocardial ischemia was not different between patients with and without chest pain during exercise stress testing.

BACKGROUND AND OBJECTIVES: Most reports about coronary angiographic findings in acute myocardial infarction were done after thrombolytic therapy or several days after onset of symptom. The aim of this study is to evaluate coronary angiographic findings in patients with AMI within 24 hours after onset of symptoms and without thrombolytic therapy. Also we evaluated the correlation between the risk factors and severity of coronary artery disease. MATERIALS AND METHODS: We studied 70 patients with acute myocardial infarction admitted to Kyungpook National University Hospital (KNUH) from November 1997 to January 1999, and evaluated the clincial and coronary angiographic findings. We analyzed risk factors of coronary artery disease: age, total cholesterol, tiglyceride, high density lipoprotein (HDL)-cholesterol, low density lipoprotein (LDL)-cholesterol, hypertension, smoking, diabetes and family history of CAD. Coronary angiography was done immediately after the arrival at emergency room (door-to- angiography time). Exclusion criteria were delayed arrival (more than 24 hours after symptom onset), previous history of anticoagulation or medication of antiplatelet agents. RESULTS: 1) Among 70 patients (M/F: 53/17), 59 patients had Q wave myocardial infarction (QMI) (84%), 11 patients had non-Q wave-MI (NQMI) (16%). 2) The mean age was 61+/-12.2 years (range: 26 to 82 years). 3) The mean time from the onset of chest pain to angiography was 6.2+/-4.7 hours. 4) Twenty eight patients (40%) had one-vessel disease, 25 (36%) had two-vessel disease and 17 (24%) had three-vessel disease. 5) The location of infarct related arteries were as follows: LAD in 33 (47%), LCX in 13 (19%) and RCA in 24 (34%). 6) The mean diameter stenosis of infarct related artery (IRA) was 95+/-10.9%. According to the American College of Cardiology/American Heart Association (ACC/AHA) classification of IRA, type B lesion occurred most commonly in 56 patients (80%). 7) Thrombus was observed in 44 patients (63%) with QMI versus 3 patients (27%) with NQMI (p=0.006). 8) Calcifications of the wall of coronary arteries were observed in 28 patients (40%) and correlated with ages of patients. 9) History of cigarette smoking was present in 73%, hypertension in 31% and hypercholesterolemia in 15% of patients. The mean number of risk factor for each patient was 1.3. 10) Multivessel disease was significantly more frequent in patients who had two more risk factors. 11) The frequency of cigarette smoking was greater and the level of plasma triglyceride were higher in patients under 50 years of age. 12) One patient died during coronary angiography and another 2 patients died at 5 and 8 days after coronary angiography due to cardigenic shock. CONCLUSION: In immediate coronary angiographic findings in patients with AMI, multivessel disease and thrombus, and severe stenosis of IRA were observed more frequently than other studies after thrombolytic therapy or after several days of delay. Multivessel disease was significantly more frequent in the patients who had two or more risk factors of atherosclerosis.

BACKGROUND AND OBJECTIVES: The intracoronary stent may be useful in the preventing of abrupt closure and coronary restenosis after coronary angioplasty, and recently primary stenting has been one of therapeutic modalities. We assessed the clinical and angiographic results of primary NIR stenting in patients with acute myocardial infarction (AMI). MATERIALS AND METHODS: Between November 1997 to January 1999, 55 stentings with NIR stents were done in 51 patients with acute myocardial infarction. Angiographic follow-up was available at 7+/-2.3 days in 35 patients. RESULTS: 1) Among 51 patients (M/F: 37/14), 44 patients had Q-wave MI (86%), 7 patients had non-Q-wave MI (14%). 2) The mean age was 61+/-12.4 years (range: 26 to 82 years). 3) The mean time from the onset of chest pain to the arrival at emergency room was 4.6 +/- 4.2 hours. The mean door-to-balloon time was 93+/-46 minutes 4) Treated vessels were as follows: 28 in LAD, 17 in RCA, 10 in LCX. 5) The indications for stent implantation were suboptimal angiographic results after PTCA in 38 lesions (69%), dissection in 9 lesions (16%), abrupt vessel closure in 1 lesion and elective in 7 lesions (13%). 6) Single stent implantation was done in 47 patients. Overlapping stents were done in 4 patients. 7) A procedure related complication occurred in one patient, peri-stent dissection without flow limitation. 8) Full expansion of the stent failed in three lesions with coronary calcifications and the residual stenosis was 35, 40, 50% in each case. In these cases, in-stent thrombus was not demonstrated in follow up angiography. 9) The minimal lumen diameter increased from 0.11+/-0.39 to 2.96+/-0.40 mm. 10) Angiographic follow-up on 38 stents in 35 patients demonstrated in-stent thrombus in 3 stents, in-stent restenosis in 1 stent. But in-stent flow limitations were not found in these 4 cases and TIMI III flow were maintained. Patients with Q-wave MI and coronary thrombus on initial angiography were more prone to subacute thrombosis. CONCLUSION: The NIR stent could be used successfully in primary coronary stenting in acute myocardial infarction. The present study shows relatively low risk of subacute stent thrombosis. The rate of restenosis needs to be confirmed by long term study.

PURPOSE: Myocardial perfusion scintigraphy is a useful technique to diagnose and to predict prognosis in patients with suspected or known coronary artery disease. The purpose of the present study is to evaluate the prognostic value of normal exercise (99m)Tc-MIRI myocardial perfusion single photon emission computed tomography (SPECT) an(l to analyze results with regard to those of exercise. electrocardiography or coronary angiography. MATERIALS AND METHODS: We evaluated 30) patients (mean age S2+/-10 years, 166 males and 135 females) with normal exercise (99m)Tc-MIBI myocardial perfusion SPECT performed for suspected coronary artery disease. Subjects were evaluated for cardiac events and followed for 8-55 months (mean 19+/-10 months) after imaging. RESULTS: During the follow-up period, there was no cardiac death but only one non-fatal myocardial infarction (event rate 0,21%: per year). In addition, only one patient underwent coronary revascularization. There was no significant difference in cardiac event rate between patients with positive (n=27) and negative (n-235) exercise electrocardiography (p:NS), There was no cardiac event in ]7 patients who underwent coronary angiography (4 patients with >50% luminal narrowing, 2 patients with vasospasm and 11 patients with no significant lesion). CONCLUSION: Patients with normal exercise (99m)Tc-MIBI myocardial perfusion SPECT has a very low risk for cardiac events regardless of exercise electrocardiographic and coronary angiographic findings.

BACKGROUND: Ventricular function is one of the important prognostic factors in patients with coronary artery disease. Among noninvasive approaches for the evaluation of ventricular performance, radionuclide ventriculo-graphy has shown to be of particular values in the patients with myocardial infarction. We have evaluated ven-tricular function with ECG-gated blood pool scan (GBPS) in patients with myocardial infarction of different locations and compared right and left ventricular functions. METHOD: Left and right ventricular function was assessed with multigated blood pool scan in 49 patients at 2-3 weeks after acute myocardial infarction (anterior infarction=23, inferior infarction=19, and lateral infarction=7). Left ventricular ejection fraction (LVEF), right ventricular ejection fraction (RVEF), maximal emptying rate, maximal filling rate, phase angle and full width at half maximum (FWHM) of phase angles were measured during rest. RESULTS: 1) LVEF was signifi-cantly lower in the patients with anterior myocardial infarction (32.2%) than that of inferior (46.5%, p<0.001) or lateral infarction (45.5%, p<0.05), but not different between inferior and lateral infarction. 2) RVEF was significantly lower in the patients with inferior myocardial infarction (24.6%) than that of anterior (30.5%, p<0.05) or lateral infarction (36.1%, p<0.001), and RVEF of anterior infarction was significantly lower than that of lateral infarction (p<0.05). 3) Phase angle and FWHM of left ventricle and right ventricle phase histogram were not significantly different among the patients groups with different infarct sites. CONCLUSIONS: Ventricular function was differently affected by different infarct sites. Inferior infarction resulted in a greater reduction in right ventricular ejection fraction. In contrast, LVEF was greatly depressed in anterior infarction than in inferior infarction.

PURPOSE: The sensitivity of ST-depression in the electrocardiogram during exercise is influenced by the level of efforts. However, unlike the prevalence of ST-depression on exercise ECG, the degree of exercise is reported to do not influence the diagnostic ability of myocardial perfusion scan. Furthermore, the relation between the prevalence of myocardial ischemia and effort is still controversial. We evaluated the effect of the degree of exercise on the ability of SPECT imaging to detect coronary artery stenosis. MATERIALS AND METHODS: The patient population was comprised of 111 patients (73 men and 38 women, mean age 56 years) who underwent an exercise test in conjunction with Tc-99m MIBI and cardiac catheterization within 3 months apart each other. The degree of exercies was classified into four groups according to the percentage of maximal predicted heart rate. The sensitivity and specificity was compared between each group. RESULTS: The overall diagnostic sensitivity was significantly higher with Tc-99m MIBI SPECT than exercise ECG. The specificity was not significantly different between two tests. Sensitivity and specificity of Tc-99m MIBI was not different between four groups. Sensitivity for individual coronary stenosis seemed to be lower in subjects who had premature termination of exercise due to early appearance of ST depression. CONCLUSION: These RESULTS suggest that the overall diagnostic sensitivity of Tc-99m MIBI myocardial perfusion SPECT is not significantly affected by the degree of exercise in stable patients undergoing symptom-limited treadmill exercise testing. Myocardial perfusion SPECT imaging should be added to routine exercise stress testing for the detection of coronary artery disease.
