Cough Syncope Induced by Gastroesophageal Reflux.
Korean Circulation Journal.2004;34(7):718-720. doi:10.4070/kcj.2004.34.7.718
Episodes of loss of consciousness occur in various situations. Although cough syncope has been recognized and described over a hundred years ago, this condition remains a fascinating and incompletely understood clinical entity. In the present case, syncope sometimes occurred during vigorous paroxysms of non-productive coughing that were due to gastroesophageal reflux disease.

A Case of Delayed Onset Tirofiban Induced Thrombocytopenia in a Chronic Renal Failure Patient.
Korean Circulation Journal.2004;34(7):715-717. doi:10.4070/kcj.2004.34.7.715
Compared with heparin induced thrombocytopenia (HIT), glycoprotein (GP) IIb/IIIa inhibitor induced thrombocytopenia is characterized by a rapid and profound fall in the platelet count. In severe cases, the platelet count decreases below 20,000/mm3 within the initial 24 hours after exposure to the drugs. It is often associated with severe bleeding complications. Tirofiban is one of the GP IIb/IIIa inhibitors. A case of severe thrombocytopenia in a 60-year-old man, with chronic renal failure (CRF) and acute myocardial infarction (AMI), was recently experienced. Tirofiban was administered to treat the AMI without ST segment elevation. The platelet count fell to 1,000/mm3 with hemoptysis and petechiae 80 hours after the initiation of tirofiban infusion. In this case, the clinical course was similar to that of the typical GP IIb/IIIa inhibitors induced thrombocytopenia, with the exception that its onset time was unusually delayed. The platelet count was normalized in 9 days after cessation of tirofiban infusion. Thus, this unusual case is reported as delayed onset tirofiban induced thrombocytopenia in a CRF patient.

A Case of Turner's Syndrome Associated with Atrial Septal Defect and Mitral Valve Prolapse.
Korean Circulation Journal.1995;25(4):875-879. doi:10.4070/kcj.1995.25.4.875
We experience a case of 34-year-old Turner's syndrome(45, XO) associated with atrial septal defect(secondum type) and mitral valve prolapse who was admitten due to moderate exertional dyspnea. It is well know hat chromosomal abnormality is one of the etiology of congenital heart disease. In case of Turner's syndrome, coarctation of aorta or bocuspid aortic valve is frequently combined, but atrial septal defect simultaneously with mitral valve prolapse is not reported till now in Krea. We report this case with a brief review of the literature.

A Case of Asymmetric Septal Hypertrophy Combined with Conn's Syndrome.
Korean Circulation Journal.1995;25(4):868-874. doi:10.4070/kcj.1995.25.4.868
We report a case of a 44 year old femele with unilateral aldosterone-proudcing adrenal adenoma characterized by hypertension, plasma aldosterone excess, and low plasma renin, commonly but not invariably with hypokalemia. She also had asymmetric septal hypertrophy of left ventricle established with two-dimensional echocardiography. The electrocardiogram showed inverted T wave and prominent U wave with high QRS voltage on precordial leads. In the case of this patient, we are not sure whether asymmetric septal hypertrophy was caused by secondary hypertension and chronic aldosterone excess of primary aldosteronism, or hypertrophic cardiomyopathy per se, so further long=term follow-up is required to determine it. Following the successful unilateral adrenalectomy, however, the systemic pressure fell down to the normal level and electrolyte abnormalities were corrected immediaterly within a few days and the modest regression in septal hypertrophy was noted in one year, suggesting that the promary aldosteronism contributes to the development or porgression of asymmetric septal hepertrophy.

Transesophageal Echocardiographic Findings in 3 Cases of Takayasu's Arteritis.
Korean Circulation Journal.1995;25(4):861-867. doi:10.4070/kcj.1995.25.4.861
BACKGROUND: Takayasu's arteritis is a chronic non-specific inflammatory disease of arteries and it is known that aorta and its major branches are most commonly invoved. Its etiology is still unknown but the basic process is marked intimal proliferation, fibrosis and fibrous scarring with degeneration of the elastic fibers of the media. The proliferative and cicatrical process leads to luminal narrowing, stenosis, localized aneurysm, postsenotic dilatation and calcification in the involved arterial wall. Little attention has been paid to the diagnostic value of transesophageal echocardiography(TEE) in Takayasu's arteritis. METHODS: We evaluated transesophageal echocardiographic findings of aortic lesions in 3 cases of Takayasu's arteritis. RESULTS: The transesophageal echocardiographic findings of aortic lesions in Takayasu's arteritis characteristically showed relatively long sehmental luminal narrowing caused by marked intimal proliferation and contracture fo aortic wasll. The morphology of intimal thickening was characteristically circumferential, concentric and the size of the aorta itself was decreased by contracture as compared with atherosclerotic changes involving aorta. Besides these findings were consistent with angiographic findings. The common types of Takayasu's arteritis which we will meet clinically are known as type I or III. Indeed, 3 cases described in this paper are all type 3 patients. According to that fact, most of Takayasu's arterits may have aortic lesions that could be easily accessible by TEE and the degree of deformity of the aorta can be evaluated using TEE. CONCLUSION: The transesophageal echocardiography may be a valuable diagnostic tool for the evaluation of aortic wall and luminal status in the patients with Takayasu's arteritis.

Efficacy of Ciprofibrate Monotherapy in Patients with Type II and Type IV Hyperlipidemia.
Korean Circulation Journal.1995;25(4):855-860. doi:10.4070/kcj.1995.25.4.855
BACKGROUND: The ciprofibrate, 3rd generation fibrate derivative, is known as an effective hypolipidemic drug in both hypercholesterolemia and hypertriglyceridemia. We studied the efficacy and side effects of ciprofibrate dmonotherapy in patients with primary type II and type IV hyperlipidemia. METHOD: Patients who showed 12-hours fasting serum total cholesterol level more than 240mg% and/or serum triglyceride level more than 250mg% were enrolled to diet therapy. After 12 weeks of diet therapy serum lipid profiles were checked and the drug therapy was considered according to the above mentioned guidelines. The ciprofibrate 100mg p.o qd was administrated and the patients had regular follow-up every 6 weeks for 12 weeks. RESULTS: The total study population was 32 patients. Fifteen patients were type II hyperlipidemia and seventeen patients were type IV hyperlipidemia. The drug was well tolerated in all patients. There was mild gastrointestinal side effects in 9% of study patients but no patients discontinued ciprofibrate due to side effects. There was mild and transient serum CK elevation less than 3 times of baslines in 5(15%) patients. The LFT, serum uric acid, BUN and creatinine level did not show any significant changes during therapy. Serum total cholesterol and apolipoprotein B level in patients with type II hyperlipidemia showed significant reduction after 6week of therapy. The mean reduction was 25% and 32% respectively. Serum triglyceride level in patients with type IV hyperlipidemia decreased by 55%. The reduction of total cholesterol more than 25% could be achieved in 50% of type II hyperlipidemia and the reduction of triglyceride more than 25% could be achieved in 93% of type IV hyperlipidemia. CONCLUSION: The ciprofibrate is effective and sage hypolidipemic drug in patients with primary type II and type IV hyperlipidemia.

BACKGROUND: Inotropic agents have been shown to improve cardiac function in patients with congestive heart failure. The purpose of the present study is to evaluate the short-term efficacy and safety of denopamine(Cardopamin(R)), and orally available beta-stimulant, in patients with chronic congestive heart failure. SUBJECTS AND METHODS: Twenty-four patients(54.1+/-10.9 years, male:female=1.4:1) with chronic congestive heart failure whose functional classes were equal or greater than New York Heart Association(NYHA) Class II were enrolled in this study after informed consents were obtained. Upon completion of baseline evaluation, denopamine(Cardopamin(R)) was administered orally, startion with 15 mg per day and increased to 30 mg per day according to the clinical response of each patient. Blood pressure, heart rate, electrocardiographic(EKG) findings, AST, BUN, and creatinine were also followed up at 4 weeks' interval. The clinical effects and side effects at 4 weeks' interbal and echocardiographic examination at baseline and 8 weeks after trentment were evaluated. RESULTS: Mean dosage of denopamine(Cardopamin(R)) was 22.9+/-5.3mg per day. The clinical symptoms of 18(75%) of 24 patients were improved. The echocardiographic follow-up revealed a significant decrease in left vetricular(LV) end-Systolic dimemsion(fron 4.8+/-0.2mm to 4.5+/-0.1mm. p<0.005) and LV end-systolic volume(from 92.0+/-8.5ml to 80.3+/-4.5ml, p<0.005). However, there was no significant interval change in LV end-diastolic dimension, LV end-diastolic volume, ejection fraction, and fractional shortening. Blood pressure, heart rate, EKG findings, AST, BUN, and creatinine were not changed significantly during treatment. CONCLUSION: Above results suggest that short-term therapy of denopamine(Cardopamin(R)) may improve clinical symptom with no side effect in patients with chronic congestive heart failure, but the long-term efficacy remains to be determined with a randomized long-term follow up study.

BACKGROUND: Hypertonic solutions are using in emergency patients including refractory shock. The effects of the hyperosmotic solutions for the cardiac contractile effect has remained unclear. To study the mechanism of increase in twitch force by hypertonic solution, memberane potential, intracellular sodium activities(aNia), and twitch force were measured simultaneously in 1 Hz-driven canine Purkinje fibers and guinea pig papillary muscles. METHODS: To increase osmolarity, 20, 40, and 80 mOsm glucose, NaCl or mannitol was added to normal Tyrode solution. We used the conventional and Na(+)-selective microelectrodes, to study the membrane potential and intracellular sodium activity. Changes in twitch force were evaluated also by tension tranducer. RESULTS: 1) Hyperosmolar glucose or NaCl added to normal Tyrode solution produced membrane pontential hyperpolarization, increase in aNia, and increase in twitch force in dog Purkinje fibers. Increase in twitch force was related to decrease in the ratio of aNia to extracellular sodium activity(aNoa). NaCl-inducedd aNia increase was not blocked by 10(-5)M tetrodotoxin, a fast sodium channel blocker. 2) Hyperosmolar glucose or mannitol added to normal Tyrode solution produced membrane potential hyperpolarization, increase in aNia, and increase in twitch force in guinea pig papillary muscles. However, the addition of hyperosmolar NaCl did not affect on membrane potential, but produced increase in aNia, and decrease in twitch force. 3) Prolonging effect of hyperosmolar glucose on duration of action potential was smaller than that of NaCl or mannitol in Purkinje fibers and papillary muscles. 4) Increase in twich force produced by ECF Na+reduction or by hyperosmotic solution was reated to decrase in the aNia ratio. 5) Relationship curve between increase in twitch force and aNoa/aNia ratio in hyperosmolr solution was less steeper than that in ECF Na(+)-reduced solution. CONCLUSION: The above results suggested that hyperosmolar solution-induced twitch force change was related to aNoa/aNia ratio change which influenced intracellular calcium activity via Na(+)-Ca(2+)exchange.

Effect of Verapamil on the Cyclic Flow Reductions of Rabbit Carotid Stenosis.
Korean Circulation Journal.1995;25(4):830-837. doi:10.4070/kcj.1995.25.4.830
Previous studies have shown that experimental canine coronary or rabbit cardtid qrtery stenosis that is associated with endothelial injury results in a typical pattern of blood flow characterized by gradual decreases in arterial flow followed by restorations of flow to normal values. This pattern of flow, called cyclic flow reduction(CFR), is the consequence of recurrent platelet aggregation at the site of the stenosis and endothelial injury and subsequent dislodgement of the thrombus. This study was designed to test the efficacy of verapamil in ingibiting in vivo platelet aggregation in a rabbit model of cardotid artery stenosis and ecdothelial injury. Carotid blood flow was measured continuously with a electromagnetic flowmeter probe that is positioned proximal to the constrictor. During placement of constrictor and angioplasty balloon, CFR developed in 8 of 20 rabbits with a mean frequency of 10.0+/-2.2 cycles/h. CFRs were observed for 30min, and IV verapamil was administered till declining of blood pressure(up to 100ug/kg). After intravenous verapamil, the mean frequency of CFR insignificantly decreased to 8.7+/-2.1 cycles/h(p=ns). After 20mg/kg of aspirin were given intravenously, the CFR were abolished in 5 rabbits, the mean frequency of CFR decreased in 1 rabbit, and no significant change was observed in 2 rabbits. It is concluded that verapamil is relatively ineffective in inhibiting in vivo platelet aggregation at doses that don't change hemodynamics significantly.
