BACKGROUND Myocardial fibrosis is the major factor that regulates left ventricular (LV) diastolic function. Pioglitazone, an anti-diabetic drug, is reported to improve the LV diastolic function in diabetic patients, but its influence on myocardial fibrosis has not been clarified. We evaluated the effect of pioglitazone on LV diastolic function and(More)
Luteinizing hormone-releasing hormone analogue, 3.6 mg goserelin acetate and flutamide, 375 mg per day were used to treat metastatic prostate cancer in a 66-year-old male. Marked increase in serum aminotransferases and total bilirubin levels was noted after 7 weeks of treatment. The enzyme levels returned to normal at 2 months following discontinuation of(More)
OBJECTIVES This study investigated the effect of pioglitazone, an insulin sensitizer, on left ventricular diastolic function in type 2 diabetic patients. METHODS Various echocardiographic parameters such as left ventricular ejection fraction, transmitral E/A ratio (E/A), deceleration time of E, isovolumetric relaxation time and left ventricular Tei index(More)
BACKGROUND Endothelial dysfunction is closely related to cardiovascular events. Several studies have documented that angiotensin II type 1 receptor blockers (ARB) improve peripheral endothelial dysfunction. However, the effect of ARB on coronary endothelial function remains elusive. The purpose of this study was to ascertain the beneficial effects of ARB on(More)
A 43-year-old men presented with left supraclavicular growing mass. Ultrasonography revealed a 31 x 21 mm solid mass with a homogeneous echoic pattern. Lymph node metastasis of some malignant neoplasms was highly suspected. However, whole body evaluation with computed tomographic scan revealed no findings in the primary region. In addition, tumor markers(More)
