We sought to clarify whether a single-bolus intravenous administration of sodium bicarbonate in addition to hydration with sodium chloride prevents contrast-induced nephropathy (CIN). One hundred forty-four patients with mild renal insufficiency (serum creatinine >1.1 to <2.0 mg/dl) undergoing an elective coronary procedure were randomly assigned to the(More)
The investigators prospectively examined 625 consecutive patients who underwent coronary multislice computed tomography (MSCT) for suspected coronary artery disease (CAD) and evaluated the presence or absence of cancers and other noncardiac abnormalities on the original transverse sectional images of MSCT. Eight patients with known cancers were excluded(More)
INTRODUCTION Inherited antithrombin (AT) deficiency is associated with a predisposition to familial venous thromboembolic disease. We analyzed the AT gene in three unrelated patients with an AT deficiency who developed thrombosis. MATERIALS AND METHODS We analyzed the SERPINC1 gene in three patients. Additionally, we expressed the three mutants in the(More)
BACKGROUND The association between sleep-disordered breathing (SDB) assessed by polysomnography and cardiac sympathetic nerve activity (SNA) assessed by cardiac iodine-123 metaiodobenzylguanidine (123I-MIBG) imaging has not been investigated in patients with chronic heart failure (CHF). METHODS AND RESULTS We performed cardiac 123I-MIBG scintigraphy and(More)
Left ventricular (LV) contractility and relaxation are physiologically coupled on the basis of intracellular calcium cycling. The relation has been reported to be unique. However, this may not be always true if relaxation is predominantly impaired. Direct current counter (DC) shocks develop myocardial interstitial edema, inducing diastolic heart failure.(More)
Obtaining a right-chest electrocardiogram is essential for diagnosing concomitant right ventricular infarction in patients with inferior wall acute myocardial infarctions. A software program to synthesize right-chest electrocardiographic waveforms from 12-lead electrocardiographic waveforms is available in Japan. However, its reliability has not been fully(More)
The mechanochemical model proposed in 1983 by G. Oster, J. D. Murray and A. K. Harris has been deployed to describe various morphological phenomena in biology, such as feather bud formation [17] and angiogenesis and vasculogenesis [10, 13]. In this article, we apply a mechanochemical model to the formation of a somite to better understand the role that the(More)
Previous studies have shown that the analysis of ST-segment deviation in lead aVR on admission provides useful information on angiographic coronary anatomy and risk stratification in acute coronary syndromes. However, the association between ST-segment deviation in lead aVR on admission and left ventricular (LV) function has not been fully investigated in(More)
