BACKGROUND: The dipyridamole and dobutamine stress echocardiography have been studied as a non-invasive diagnostic test in coronary artery disease. Recently, some authors have extended the usefulness of these tests to predicting the prognosis of myocardial infarction patients. But as far as we know, there was no literature which tried boh tests to the same infarcted patients group. So, we performed both tests in the 23 infarcted patients to compare and evaluate both tests as predicting the prognosis in myocardial infarction. METHODS: Patients underwent (1) two-dimensional echocardiography under basal condition and after dipyridamole infusion for 4 minites at the dose of 0.14mg/kg/min, (2) another two dimensional echocardiography under basal and during dobutamine infusion at each dose of 5 to a maximum of 20microg/kg/min at 1 or 2 days after dipyridamole stress echocardiography, and (3) coronary and left ventricular angiography. Preinfusion and peak infusion images were analyzed independently by two different observers using Nova Micro Sonic soft were(DataVueII and ColorVue II analysis system). The segmental wall motions were scored as follows ; hyperkinetic : 1, normal : 2, hypokinetic : 3, akinetic : 4. THe test response was considered positive if abnormal wall motion and reduced myocardial thickening were observed during drug infusion at the vascular distributions except the akinetic infarcted segment identified during basal condition. The coronary angiography was analyzed by measuring the maximal luminal diameter stenosis with caliper and 50% or greater diameter narrowing was considered significant. The sensitivity and specificity were calculated by comparing echocardiographic prediction and angiographic findings. RESULTS: 1) Among 22 patients with sufficient image in dipyridamole stress echocardiography, 13 patients have myltivessel coronary disease without resting akinesia of non-infarcted segments. Only 5 patients showed positive findings in dipyridamole stress echocardiography(sensitivity, 38.4%). Among 9 patients who has single or minimal disease, 9 patients were negative finding(specificity, 100%). 2) Among 21 patients with sufficient image in dobutamine stress echocardiography, 12 patients have multivessel coronary disease without resting akinesia of non-infarcted segments. 7 patients showed positive finding in dobutamine stress echocardiography(sensitivity, 58.3%). Among 9 patients who has single or minimal disease, 8 patients showed negative finding(specificity, 88.8%). 3) In hemodynamic changes, dipyridamole stress echocardiography showed significant changes in heart rates and double products and dobutamine stress echocardiography showed significant changes in heart rates, systolic blood pressure and double products. 4) There was no significant side effect during both stress tests inacute and old myocardial infarction patients. CONCLUSION: 1) The dobutamine and dipyridamole stress echocardiography are safe and easy test for myocardial infarction patients. 2) The dobutamine stress echocardiography has higher sensitivity than dipyrdamole stress echocardiography for identifying multivessel coronary disease in myocardial infarction patients but the dose of both drugs were relatively small to get the adequate results. So the high dose of drugs must be tried in feature study.

BACKGROUND: Evaluating the segmental wall motion of left ventricle is important in patients with myocardial infarction for choosing therapeutic modality and predicting prognosis. Radionuclide Multigated Angiography(MUGA) is a reliable noninvasive method for the evaluation of left ventricular performance. Methods : MUGA scan(LV ejection fraction, phase image histogram, regional wall motion) was performed and analyzed in 45 patients with myocardial infarction(31 : acute MI, 14: old MI) and 13 normal controls. RESULTS: 1) The LVEF of acute and old MI group was significantly reduced and the SDph of acute and old MI group was significantly increased as compared with that of control group(p<0.05). 2) In acute MI group, the LVEF of group without, IV Urokinase was more reduced than that of group with IV Urokinase and the SDph of group without IV Urokinase was more increased than that of group with IV Urokinase(p<0.05). As a result of wall motion scoring, the linear correlation exists between SDPh and sum of wall motion scoring(r=0.62, p<0.01). 3) In MI group, the LVEF of anterior wall MI was more reduced than that of inferior wall MI and the SDPh of anterior wall MI was more increased than that of inferior wall MI(p<0.05). 4) In acute anterior wall MI, the reverse correlation exists between LVEF and SDPh and the linear correlation exists between sum of wall motion scoring and SDPh(r=-0.73, 0.72, p<0.01). But there are no statistical significances of correlation between them in acute inferior MI(r=-0.44, 0.42, p>0.05), in old anterior MI(r=-0.65, 0.47, p>0.05) and in old inferior MI(r=-0.47, 0.46, P>0.05). CONCLUSION: These results suggest that Phase angle(SDPh) is thought to be valuable index to evaluate left ventricular function with application of other indeces in Myocardial infarction. Left ventricular function measured by SDph in acute or anterior MI is lower than old or inferior MI.

Percutaneous mitral ballon valvuloplasty(PMV) is an effective nonsurgical procedure for patients with mitral stenosis. PMV was performed in 13 patients(mean age, 41 years) with mitral stenosis. All patients underwent echophonocardiography(Echophono) before and after PMV. Two dilatation balloons were used in which the diameters approximately equaled the mitral valve annulus diameter as determined. After PMV, the mean mitral valve pressure gradient decreased(22.3+/-1.89mmHg to 5.2+/-2.6mmHg), the mean left atrial pressure decreased(21.3+/-5.1mmHg to 9.0+/-4.5mmHg) and the mitral valve area increased from 0.8+/-0.3cm2 to 1.7+/-0.6cm2. The Echophono data are correlated with clinical and hemodynamic changes produced by PMV. PMV resulted in echophono changes consistent with decresed severity of mitral stenosis ; shortening of Q-S1, from 88+/-14 to 73+/-11 mses(p<0.01) and (Q-S1)-(S2-OS), from 0.9+/-1.7 to -2.1+/-1.6(p<0.001) ; prolongation of S2-OS from 80+/-15 to 103+/-14 msec(p<0.001) and increase of EF slope from 14.7+/-5.4 to 26.7+/-8.1 mm/sec(p<0.001). Compared with pre-PMV, post-PMV Echophono showed significant decrease in the severity of mitral stenosis. Thus Echophono is a simple, low cost method helpful in evaluation and follow-up patients undergoing PMV.

We experienced a case of arteriovenous hemangioma showing Dariers sign on the forehead of a 43-year-old man. He presented with a single, 1 * 1.5cm sized, violaceous, asymptomatic nodule with a history of an intermittent wheal at the lesional site. This skin lesion showed Dariers sign clinically and proliferation of mast cells histopathologically with the punch biopsy specirnen suggesting urticaria pig- mentosa. Howerer, we could diagnose it as a arteriovenous hemangioma on complete excision, as the specimen showed arteriovenous proliferation with increased mast cells in a perivascular pattern. This case showed confusing clinical signs and showed the importance of complete excision for the diagnosis of a small skin tumor especially when a vascular proliferating tumor is suspected.

BACKGROUND: Efficacy of percutaneous transluminal angioplasty(PTA) in the treatment of Peripheral arterial disease has been established. Complications such ans PTA-induced dissections or residual stenosis with occasional mural thrombi have been reported, which compromise the results. New procedures can be used in combination with PTA to improve the immediate and long term results, such ans prolonged balloon inflation, atherectomy, or implantation of endovascular prosthesis. In addition, the occurrence of other lesions, such as spontaneous or post-catheterization dissection or post-PTA restenosis, has prompted the insertion of a vascular stent. But there was few reports on stenting for peripheral arterial disease in Korea. METHODS: To evaluate the safety, efficacy and stability of stent in peripheral arterial disease, twenty-six consecutive symptomatic patients with 37 peripheral lesions were treated with 39 balloon expandable(33 Strecker and 6 Palmaz)stents with or without prior balloon angioplasty in the period of March 1991 and February 1994. RESULTS: The major cause of disease was arteriosclerosis(22 out of 26). The implantation sites for our study include 22 in common iliac artery, 11 in external iliac artery 2 in aorta, subclavian artery, superficial femoral artery each other. Indication for stent deployment were primarily suboptimal results(19 lesions), insufficient PTA such as dissections(4), restenosis after previous PTA(2), and primary stenting was performed without preceding therapeutic PTA(10). Stent deployment was technically successful in 24 of the 26 patients(92%) and clinical success rate was in 25 of the 26 patients treated(96%). Hemodynamic change revealed markedly improvement before and after stenting(peak pressure difference from 66.329.0mmHg to 9.1+/-7.1mmHg; Mean pressure difference from 33.0+/-22.5mmHg to 4.7+/-4.3mmHg). There were two procedural complications which included one stent migration and one artery perforation. During the 7 months of follow-up(1-18 momths), two restenosis occurred. One patient died due to cerebral hemorrhage during thrombolysis with urokinase. CONCLUSION: The stent deployment is relatively safe and very effective primary therapeutic modality and may abolish the limitation of PTA such as suboptimal result, dissection with sudden occlusion and restenosis in peripheral vascular disease and highly recommended in selected cases.

In order to investigate the efficacy and safety of oral fosinopril, a new phosphorus containing angiotensin converting enzyme inhibitor, a single dose of 10 to 20mg was administered in 23 hypertensive patients with diastotic blood pressure above 95mmHg and all other anti-hypertensive agents were not administered during 4 weeks of study. Blood pressure and heart rate were measured on the 2nd and 4th week of therapy. The complete blood count with platelet count, blood chemistry by SMA-12 and serum electrolytes were performed at the begining and 4th week of therapy. The urinalysis and electrocardiography were performed at the beginning and 4th week of therapy. Any kinds of side effects were actively questioned by the examining physicians. The following results were obtained : 1) At the beginning and 4th weeks of therapy, the average systolic and diastolic pressure were 170.0+/-17.6/101.6+/-6.1mmHg, 142.7+/-15.1/87.3+/-6.7mmHg respectively. The systolic and diastolic blood pressure were declined statistically significantly(p<0.05) throughout the period of treatment and diastolic blood pressure of all subjects except 3 patients(86%) was maintained below 90mmHg after 4th week of treatment. 2) There was no significant change in the pulse rate before and after therapy. 3) There were no significant changes in blood chemistry, serum electrolytes, hematologic findings, urinalysis and electrocardiographic findigns. 4) side effect were developed in 5 patients(23%) with dry cough, 3 patients(13%) with headache and 2 patients with facial edema but side effects were mostly mild in nature without potenitally serious episodes. These results suggested that antihypertensive therapy with onec-daily fosinopril was effective and well tolerated in essential hypertensive patients.

Lipoprotein(a)[Lp(a)] is a LDL-like particle with a glycoprotein called apo(a) attached to its apoB through disulfide bond. Many case-control studies support the opinion that plasma Lp(a) levels were associated with coronary artery disease. This study was conducted to assess the relationship between plasma Lp(a) level and coronary artery disease in Korean population. Serum levels of Lp(a), in addition to other lipids and known clinical risk factors for coronary artery disease were determined in 92 subjects undergoing coronary angiography. Among them 30 patients had no obstruction in the coronary artery(cath-control group), while the others revealed the presence of coronary artery stenosis more than 50%(CAD group). The Lp(a) levels of the CAD group were significantly higher the those of cath-control group(31.8+/-25.0mg/dl vs 14.6+/-11.9mg/dl, p<0.005). Other lipids except triglycerides(166.9+/-70.5mg/dl vs 116.2+/-56.1mg/dl, p<0.005) were not significantly different between two groups. The patients with significant coronary artery disease of two or more vessels were found to have higher Lp(a) levels than those of one vessel disease. Lp(a) levels had no relations with other lipids, diabetes, smoking, hypertension and age. Stepwise discriminant analysis revealed that Lp(a) was the best discriminator among risk factors for coronary artery disease. These results suggested that Lp(a) level was a significant independent risk factor for coronary artery disease.

Secondary tricuspid regurgitation (TR) primarily develops due to left heart failure or primary pulmonary diseases. Tricuspid annular dilation, which is commonly caused by right ventricular volume and pressure overload followed by right ventricle dilation, is believed to be the main mechanism underlying secondary TR. It is reported that once the tricuspid annulus is dilated, its size cannot spontaneously return to normal, and it may continue to dilate. These reports also suggest the use of an aggressive surgical approach for secondary TR. In the present report, we describe a case of tachycardia-induced severe TR that was completely resolved without the need for surgery.
