BACKGROUND/AIMS: The aim of the present study was to evaluate the relationship between thyroid hormone levels and infarct severity in patients with ST-elevation myocardial infarction (STEMI). METHODS: We retrospectively reviewed thyroid hormone levels, infarct severity, and the extent of transmurality in 40 STEMI patients evaluated via contrast-enhanced cardiac magnetic resonance imaging. RESULTS: The high triiodothyronine (T3) group (> or = 68.3 ng/dL) exhibited a significantly higher extent of transmural involvement (late transmural enhancement > 75% after administration of gadolinium contrast agent) than did the low T3 group (60% vs. 15%; p = 0.003). However, no significant difference was evident between the high- and low-thyroid-stimulating hormone/free thyroxine (FT4) groups. When the T3 cutoff level was set to 68.3 ng/dL using a receiver operating characteristic curve, the sensitivity was 80% and the specificity 68% in terms of differentiating between those with and without transmural involvement. Upon logistic regression analysis, high T3 level was an independent predictor of transmural involvement after adjustment for the presence of diabetes mellitus (DM) and the use of glycoprotein IIb/IIIa inhibitors (odds ratio, 40.62; 95% confidence interval, 3.29 to 502; p = 0.004). CONCLUSIONS: The T3 level predicted transmural involvement that was independent of glycoprotein IIb/IIIa inhibitor use and DM positivity.

Massive thoracoabdominal aortic thrombosis is a rare finding in patients with iatrogenic Cushing syndrome in the absence of any coagulation abnormality. It frequently represents an urgent surgical situation. We report the case of an 82-year-old woman with massive aortic thrombosis secondary to iatrogenic Cushing syndrome. A follow-up computed tomography scan showed a decreased amount of thrombus in the aorta after anticoagulation therapy alone.

Coronary artery injury after thoracic injury is very rare, but can result in serious acute myocardial infarction (MI). It can be easily mistaken for chest wall pain or cardiac contusion if relying solely on a history and physical examination. We herein report a rare case of a 60-year-old female patient who presented with inferior wall ST-segment elevation MI due to right coronary artery dissection following blunt chest trauma after a traffic accident. Successful primary percutaneous coronary intervention was performed without complications.

PURPOSE: Cardiac dysfunction and hyperdynamic systemic circulation may be present in patients with cirrhosis. The purpose of this study was to identify relations between plasma levels of N-terminal-proBNP (NT-proBNP), reflecting early ventricular dysfunction, and the severity of liver disease and cardiac dysfunction in cirrhotic patients. MATERIALS and METHODS: Sixty-three cirrhotic patients and 15 controls (group 1) were enrolled in this study. Plasma levels of NT-proBNP were determined in echocardiographically examined patients, which were allocated to 1 of 3 groups according to Child-Pugh classification or into 2 groups, i.e., a compensated group without ascites (group 2) and decompensated group with ascites (group 3). RESULTS: Plasma NT-proBNP levels were significantly higher in cirrhotic patients (groups 2 and 3) than in age-matched controls (155.9 and 198.3 vs. 40.3pg/mL, respectively, p < 0.05). NT-proBNP levels were significantly increased in Child class C patients than in classes B and A (250.0 vs. 168.6 and 119.6pg/mL, respectively, p < 0.05). Left atrial dimension, wall thickness of left ventricle, and EF or E/E' were significantly increased, and EDT was prolonged in cirrhotic patients than in controls. Increased LVMI and decreased E/A ratio were noted in the group of patients with ascites as compared with the other groups. CONCLUSION: Plasma NT-proBNP levels were high in cirrhotic patients and are likely to be related to the severity of disease. Advanced cirrhosis is associated with advanced cardiac dysfunction, and NT-proBNP levels has predictive value for concomitant cardiac dysfunction and cirrhosis progression.

The present study was attempted to investigate the effect of nicorandil, which is an ATP-sensitive potassium (KATP) channel opener, on secretion of catecholamines (CA) evoked by cholinergic stimulation and membrane depolarization from the isolated perfused rat adrenal glands. The perfusion of nicorandil (0.3~3.0 mM) into an adrenal vein for 90 min produced relatively dose-and time-dependent inhibition in CA secretion evoked by ACh (5.32 mM), high K+ (a direct membrane depolarizer, 56 mM), DMPP (a selective neuronal nicotinic receptor agonist, 100micrometer for 2 min), McN-A-343 (a selective muscarinic M1 receptor agonist, 100micrometer for 4 min), Bay-K-8644 (an activator of L-type dihydropyridine Ca2+ channels, 10micrometer for 4 min) and cyclopiazonic acid (an activator of cytoplasmic Ca2+-ATPase, 10micrometer for 4 min). In adrenal glands simultaneously preloaded with nicorandil (1.0 mM) and glibenclamide (a nonspecific KATP-channel blocker, 1.0 mM), the CA secretory responses evoked by ACh, high potassium, DMPP, McN-A-343, Bay-K-8644 and cyclopiazonic acid were recovered to the considerable extent of the control release in comparison with that of nicorandil-treatment only. Taken together, the present study demonstrates that nicorandil inhibits the adrenal CA secretion in response to stimulation of cholinergic (both nicotinic and muscarinic) receptors as well as by membrane depolarization from the isolated perfused rat adrenal glands. It seems that this inhibitory effect of nicorandil may be mediated by inhibiting both Ca2+ influx and the Ca2+ release from intracellular store through activation of KATP channels in the rat adrenomedullary chromaffin cells. These results suggest that nicorandil-sensitive KATP channels may play an inhibitory role in the regulation of the rat adrenomedullary CA secretion.

PURPOSE: Obesity-related leptin and leptin receptor (OBR) have a relation to the development of cancer and metastasis and also the low survival rate for breast cancer patients. Leptin has been associated with increased aromatase activity and it displays functional cross-talk with estrogen. This study was designed to determine the relationship between the expression of leptin and OBR in breast cancer tissue and the prognosis of early-stage breast cancer patients, and especially for the tamoxifen-treated patients. MATERIALS AND METHODS: Ninety-five patients with early-stage breast cancer and who had undergone surgical treatment at Kyung Hee University Hospital between January 1994 and June 2004 were analyzed. The surgical specimens underwent immunohistochemical analysis for leptin and OBR. The patients' survival and clinical characteristics were obtained from the medical records. RESULTS: Of the 95 patients, 79 (83%) and 32 (33.7%) showed the expression of leptin and OBR in breast cancer tissue, respectively. The expression of leptin and OBR in breast cancer tissue was not significantly related to the clinicopathological characteristics, including obesity, the expression of hormonal receptor, the HER-2/neu expression, menopause, stage and the nuclear grade. The expression of leptin and OBR was not significantly related to the overall disease-free survival (DFS). For the tamoxifen-treated postmenopausal obese patients, the DFS of the leptin-positive group was higher than that of the leptin-negative group (p=0.017). CONCLUSION: The expression of leptin and OBR in breast cancer tissue may be not a prognostic factor for disease-free survival of breast cancer patients. In the future, further studies are needed to determine whether leptin expression could be a predictive factor for tamoxifen therapy in the postmenopausal obese subgroup among the early breast cancer patients.

BACKGROUND AND OBJECTIVES: Stress induced cardiomyopathy has been reported as reversible left ventricular dysfunction with electrocardiographic changes. Although the exact mechanism of this dysfunction has not been clarified, catecholamine "surge" is suspected as a potential cause of this disease. It has not been undergone the studies about the effect of chronic or recurrent psychological stress on the myocardium. We suspect that reversible ischemic change of myocardium could be induced by chronic or recurrent emotional stress. MATERIALS AND METHOD: The clinical, echocardiographic and angiographic data of 189 patients (72 women) who presented with ischemic symptoms and eletrocardiographic changes were participated. BAI (Beck anxiety inventory) and BDI (Beck Depression inventory) were obtained and analyzed for evaluation of degree of psychological stress. RESULTS: 54 patients who had left ventricular apical wall motion abnormalities without significant angiographical stenosis in the coronary artery were younger than the others with left ventricular wall motion abnormalities and angiographic stenosis. And they increased the BAI and BDI as tools of evaluation of psychological stress (p<0.05). CONCLUSION: Data of this study suggested that psychological stress can be associated with myocardial dysfunction. It can be postulated that psychological stress should be considered as one of the cause of non-coronary myocardial injury.

PURPOSE: Voice change after thyroidectomy has generally been the result of damage to the recurrent or superior laryngeal nerve. But many patients complain voice alteration without laryngeal nerve injury after thyroidectomy. The purpose of this study is to investigate whether strap muscle division results in any subjective or objective functional sequelae in voice, through long-term follow-up prospectively. METHODS: Twenty-two female patients who had undergone thyroid surgery between July 1998 and December 1999, were studied. The patients who were planned for neck dissection, who had benign laryngeal disease or vocal cord paresis, and whose vocal cord paresis were developed after thyroid surgery, were excluded from this study. Twelve patients had undergone thyroidectomy via retraction of strap muscle and ten patients had undergone thyroidectomy via cutting of strap muscle. For evaluation of voice, questionnaires for changes of voice, acoustics (fundamental frequency, jitter, shimmer, signal to noise ratio, noise to harmonic ratio, voice range), and aerodynamic (maximal phonation time) analyses were done. RESULTS: The subjective voice symptoms after thyroidectomy were disturbances of high pitch, singing, loud voice, and easy fatigue at phonation. There were no significant differences in voice parameters on acoustic and aerodynamic analyses between the strap muscle retraction group and the cutting group through long-term follow-up. CONCLUSION: We conclude that strap muscle division does not result in any subjective or objective functional problems in voice. We suggest that surgical division and reconstruction of these muscles should be employed routinely when operating on large, toxic or neoplastic glands.

The term "amyloidosis" is a disease characterized by deposition of altered proteins in the tissue. The amyloid deposit occurs always in the extracellular matrix and presents a fibrillary conformation. Primary localized tonsillar amyloidosis is a very rare disease of unknown cause that occurs in the absence of systemic involvement of amyloidosis or associated chronic inflammatory diseases. We present a case of primary localized amyloidosis in the left tonsil. Histopathologic examination of the mass revealed findings consistent with amyloidosis, which were stained with Congo Red and apple green birefringence under the polarized light fluorescence microscopy. An extensive workup for systemic involvement of amyloidosis was negative and the patient underwent tonsillectomy. The postoperative recovery was uneventful. At present, the patient has no evidence of disease or recurrence.
