BACKGROUND AND OBJECTIVES: The relationship of cold pressor, hyperventilation and exercise test responses to circadian patterns and types of angina in vasospastic angina have still not been known. The aim of this study was to identify subgoups of patients who have similar clinical features and provocation test response. MATERIALS AND METHODS: Twenty-one consecutive patients with pure vasospastic angina were studied. Six exercise tests were performed in the early morning, late morning, and late afternoon in consecutive days, and 2 hyperventilation tests and 2 cold pressor tests in the early morning. Circadian distribution and types of angina(at rest, on physical activity or both) were evaluated by clinical history, clinical records and ambulatory ECG recordings during admission and follow-up periods(mean 19+/-9 months). RESULTS: Three patterns of circadian distribution of anginal attacks were identified during all observation periods together(morning and night: MN n=, morning and afternoon or evening: M+/E n=, morning, night and afternoon and/or evening: MN+/E n=1). Exercise test was positive in 36%(40/111) without circadian variation, hyperventilation test in 66%(23/35) and cold pressor test in 6%(2/33). Neither hyperventilation test nor cold pressor test was related to circadian patterns, types or activity of angina, or numbers of spastic artery. But positive exercise test increased significantly in patients with angina on physical activity(43% vs 21%, p<0.05), high activity(57% vs 18%, p<0.01), multivessel spasm(50% vs 27%, p<0.05 ) and circadian patterns of M+/E and MN+/E(29%, 55% vs 4%, p<0.05, p<0.01). All patients with MN had rest angina and single vessel spasm. All 6 patients with M+/E had angina both at rest and on physical activity and 5 single vessel spasm. Eight of 11 patients with MN+/E had angina both at rest and on physical activity and 8 multivessel spasm. CONCLUSION: These findings suggest that hyperventilation test is highly sensitive in vasospastic angina without any relationship to clinical features, but exercise test response is related well to circadian patterns of angina attacks which are associated with characteristic clinical features.

The tricuspid valve is not a simple but a complex structure, tricuspid valve complex. This complex is composed of tricuspid orifice, annulus, valve leaflet, chordae tendineae and papillary muscles. There are flew articles about these structures. The authors studied tricuspid valve complex in 53 cases of normal korean adults, such as circumference of tricuspid annulus, the maximum diameter of the tricuspid orifice, height and breadth of the cusps, including commissures, the ratio of rough to clear zone, the number of scallops of posterior cusp, the number, length and pattern of arrangement of the several types of chordae, the number and morphological characteristics of papillary muscles.

BACKGROUND: The Freedom (TM) stent, which is one of recently developed balloon-expandable coil stents, has advantages of low profile and good trackability and flexibility. We evaluated the initial results and the late restenosis rate of Freedom (TM) stent in patients with coronary artery disease. METHOD: A total of 40 Freedom stents were implanted in 32 consecutive patients (38 lesions). The clinical diagnosis of the subjects were stable angina in 1 patient, unstable angina in 19, and acute myocardial infarction in 12. The indications of stenting were primary stenting in 11 stents, suboptimal result after PTCA in 26, and bailout procedure in 1. A mean diameter of reference artery was 3.1 mm (SD, +/-0.4) and mean of lesion length was 10.9 mm (SD, +/-5.6). Stents were implanted with a mean maximal balloon pressure of 12.1 atm (SD, +/-2.2). Follow-up angiography was done at least 3 months (mean duration, 8.7+/-3.7) after stenting for 28 lesions of 22 patients. RESULTS: All 40 stents were implanted safely except one, which was complicated with side branch occlusion. There was no case of stent thrombosis and clinical success rate was 97% (31/32). Minimal luminal diameter (MLD) was increased from 0.7 (SD, +/-0.4) to 3.0 mm (SD, +/-0.4) and % of diameter stenosis (%DS) was decreased from 78 (SD, +/-13) to 2% (SD, +/-5) immediately after stenting. The overall restenosis rate was 28% (8/28). The restenosis rate was increased in the complex lesions (complex, 38% vs simple, 0%: p=0.05) and lesion of small vessel (<3.0 mm, 50% vs > or = 3.0 mm, 20%:p=0.11). CONCLUSION: FreedomTM stent is safe and feasible in patients with various morphology of coronary lesions including small and tortuous arteries, and in lesion associated with side branches. But lesions of small vessel and complex morphology are tend to be associated with higher rates of restenosis.

Interleukin-6(IL-6) is a multifunctional cytokine, and deregulated IL-6 gene expression has been implicated as being involved in the pathogenesis of a number of diseaaes. So we measured the serum level of IL-6 to find a relationahip between uterine cervical cancer and serum IL-6 level. The serum levels of IL-6 were meesured m 54 patients adrnitted to the Severance hospital, from August, 1992 to February, 1993, of whom 27 patients were diagnosed as invasive cancer of cervix, 17 as CIN, and also utilizing 10 patiente diagnosed as uterine myoma as a control group for matched age and parity. The average serum level of IL-6 in invasive cancer, CIN, and uterine myoma were respectively 30.33pg/ml, 37.27pg/ml, and 12.45pg Jml. In 22% af cervical cancer patients (6 of 27), and 27% of CIN patients (4 of 17) studied blood levels of II-6 were detected whereas only 10% of uterine myoma (1 of 10) shorved the same result. However, the difference does not seem to be statistically significant, There was no statistically significant difference among any of the groups, and age and stage did not show any significant cmrelation, and the results need furt,ber investigations.

The relationship between infective endocarditis and mycotic aneurysm formation appers clear : In about two to ten percent of patients with infective endocarditis harbor septic intracranial aneurysms. But the pathogenesis, natural course and management of these lesions remains controversial. Aggressive medical treatment of the underlying infected cardiac valve or surgical replacement therapy have significantly reduced the morbidity and mortality rates associated with infective endocarditis. Clinical predictors of mycotic aneurysm, especially neurologic prodromes prior to rupture have been ill-defined since most series contain few patients or include patients with infective aneurysms who have no infective endoarditis. Similarly there has been no consensus regarding the indications and timing of cerebral angiography in patients with infective endocarditis. We have experienced a case of cerebral mycotic aneurysm complicated with subarachnoid hemorrhage due to infective endocarditis in a 29 year-old female patient, who admitted to our hospital because of the pain and paralysis of sudden onset in right forearm, which was diagnosed by echocardiography, brain computed tomography and 4-vessel cerebral angiography. The patient died of sudden rupture of mycotic aneurysm in the 7th hospital day despite intensive medical treatment. We report one case of cerebral mycotic aneurysm with a brief of literature.

Torsade de pointes (TdP) is a form of polymorphic ventricular tachycardia that is associated with prolongation of the QT interval. Although it occurs in many clinical settings, torsade de pointes is most commonly caused by drugs. The second generation antihistamines, including terfenadine and astemizole, have little sedation or other adverse effects on the CNS. They have been used widely to treat various allergic diseases, but it has been reported that overdoses or combinations with antifungal agents or macrolide antibiotics may lead to TdP. We report a case of TdP that occured during com-bination therapy of terfenadine and ketoconazole.

Takayasu's arteritis(TA) is a nonspecific areritis of unknown etiology affecting segmentally the aorta and its main branches, which result in stenosis, occlusion or aneurysm of involved arteries. The clinical manifestations present with a variety of symptoms such as headache, dyspnea on exertion, pain and weakness of extremities, pulse deficit, and hypertension according to involves arteries. Usually it can be managed by medical or surgical treatment, and recently by percutaneous transluminal balloon angioplasty. The type III classified by Lupi-Herrena and associates is the most frequent variety of TA. However the case of type III involving both subclavin arteries and both renal arteries has rarely been reported. We experienced a case of TA involving both subcalvian arteries, and both renal arteries presented with paroxysmal hypertension and right flank pain, in which the stenosis of both subclavian arteries were managed by percutaneous transluminal balloon angioplasty and the stenosis and occlusion of both renal arteries were successfully managed by aorto-renal bypass surgery with autogenous right iliac artery and synthetic vessel(Gortex). The patient was discharged uneventfully.

BACKGROUND: Exercise tests (ET), hyperventilation tests (HVT) and cold pressor tests (CPT) have been used to induce coronary artery spasm. However their diagnostic significance and the circadian variation of exercise test response in patients with vasospastic angina are still uncertain. METHODS: To elucidate the circadian variation of ET response and to evaluate the diagnostic significance of non-pharmacological provocation tests, 21 consecutive patients with pure vasospastic angina were studied. Six ETs were performed in the early morning, late morning, and late afternoon in consecutive days, 2 HVTs and 2 CPTs in the early morning. The circadian distribution and types of angina (at rest, on physical activity, or both) from before admission to after discharge (mean follow-up periods 19+/-9 months) were evaluated by clinical history, clinical records and Holter recordings. Circadian distribution of anginal attacks recorded through the all observation periods were classified into 3 patterns (morning and night : MN, morning and afternoon or evening : M+F/E, morning, night and afternoon and/or evening : MN+F/E). RESULTS: One hundred and eleven ETs (39 early morning, 38 late morning, 34 late afternoon tests), 35 HVTs and 33 CPTs were performed. ETs showed 14 positive responses (36%) in the early morning, 14 (37%) in the late morning and 12 (35%) in the late afternoon without any circadian variation. Among the 11 patients who underwent all 6 exercise tests, 3 patients (27%) showed at least one positive response in the early morning, 4 (36%) in the late morning and 4 (36%) in the late afternoon. Subgroups of the subjects according to the types and activity of angina and the numbers of spastic artery also failed to show any circadian variation in ET response, but M+F/E group of circadian pattern of angina showed a peak of positive response in the early morning (p<0.05). HVTs showed significantly higher positive response (23/35, 66%, p<0.05) than ETs (14/39, 36%) and CPTs showed significantly lower positive response (2/33, 6%, p<0.01) than ETs in the early morning. Double tests with more than 1 positive response couldn't increase the positive response in ETs (9/19, 47%), and CPTs (2/14, 14%) but increased significantly in HVTs(15/16, 94%, p<0.05), particularly in the group with low activity (7/8, 86%, p<0.01). ETs showed ST segment elevation in 29 (72%) and depression in 11 (28%) of the 40 positive tests, HVTs in 21 (91%) and 2 (9%) of the 23 positive tests and CPTs in 2 (100%) and 0 (0%) of the 2 positive tests. The ST segment elevation was significantly higher in HVTs than in ET (p<0.05). CONCLUSION: These findings suggest that the exercise test in the early morning do not increase positive response and is not a sensitive diagnostic test associated with occasional depression of ST segment, but hyperventilation test, especially if repeated, is a very sensitive test with predominant elevation of ST segment in patients with vasospastic angina.
