BACKGROUND Cardiovascular events are the major determinants of the prognosis of patients on chronic haemodialysis. The present study was designed to investigate whether candesartan, an angiotensin II type-1 receptor blocker, reduces the incidence of cardiovascular events in these patients. METHODS A total of 80 chronic haemodialysis patients (male/female,(More)
BACKGROUND Atherosclerotic plaques progress in a highly individual manner. The purposes of the Prediction of Progression of Coronary Artery Disease and Clinical Outcome Using Vascular Profiling of Shear Stress and Wall Morphology (PREDICTION) Study were to determine the role of local hemodynamic and vascular characteristics in coronary plaque progression(More)
BACKGROUND Few data are available on the clinical outcome of patients with acute coronary syndrome (ACS) complicated by refractory cardiogenic shock or cardiac arrest who receive percutaneous extracorporeal life support (ECLS). We investigated the in-hospital outcome and predictors of mortality in these patients. METHODS The investigation was a(More)
BACKGROUND Erythropoietin (EPO) has been shown to have effects beyond hematopoiesis, such as prevention of cardiac apoptosis. The purpose of the current study is to examine the influence of the time-course change in the serum concentration of endogenous EPO on cardiac functions in the chronic phase in patients with acute coronary syndrome, who successfully(More)
PURPOSE Radium-223 ((223)Ra), an α-emitting radionuclide, is used in unsealed radionuclide therapy for metastatic bone tumors. The demand for qualitative (223)Ra imaging is growing to optimize dosimetry. The authors simulated (223)Ra imaging using an in-house Monte Carlo simulation code and investigated the feasibility and utility of (223)Ra imaging. (More)
A 58-year-old Japanese woman presented with chronic fluctuating liver dysfunction with purpura. Raynaud's phenomenon had been diagnosed 4 years previously. At the initial examination, skin biopsy showed limited cutaneous systemic sclerosis (SSc). Laboratory investigations revealed liver dysfunction. Anti-nuclear antibodies, anti-mitochondria M2 antibody,(More)
OBJECTIVES The aim of this study was to evaluate the safety and effectiveness of a 0.010-inch guidewire and a balloon catheter for treatment of chronic total occlusion (CTO). BACKGROUND Pathological studies have shown that 60-70% of CTO lesions have microchannels of sizes equal to or less than 0.010 inch. METHODS The PIKACHU registry is a prospective,(More)
Coronary artery dominance influences the amount and anatomic location of myocardium that is perfused by the left or right coronary circulation. However, it is unknown whether coronary artery dominance also influences the distribution of coronary blood flow volume. The aim of this study was to evaluate volumetric coronary blood flow in 1,322 vessels from 496(More)
OBJECTIVE To evaluate the safety and feasibility of a new 0.010-inch guidewire and a specialized balloon catheter for the 0.010-inch guidewire in routine percutaneous coronary intervention (PCI). BACKGROUND Several reports have shown that a new 0.010-inch system is effective for specific situations where reduction of catheter size may be necessary.(More)
The frequency of radial artery occlusion was compared between patients receiving 4Fr versus 6Fr transradial coronary interventions (TRIs) in an open-label randomized trial (ClinicalTrials.gov identifier: NCT00815997). The primary outcome measure was radial artery occlusion on the day after TRI. The secondary outcome measures were the procedural success,(More)
