BACKGROUND Four new oral anticoagulants compare favourably with warfarin for stroke prevention in patients with atrial fibrillation; however, the balance between efficacy and safety in subgroups needs better definition. We aimed to assess the relative benefit of new oral anticoagulants in key subgroups, and the effects on important secondary outcomes. (More)
BACKGROUND The mortality and morbidity rates of various cardiovascular diseases differ between Western countries and Japan. The age- and gender-specific prevalence rate of atrial fibrillation (AF) in the general population of Japan was determined using the data from periodic health examinations in 2003. METHODS Data of 630,138 subjects aged 40 years or(More)
Background Although previous clinical trials demonstrated the non-inferiority of a rate control to rhythm control strategy for management of atrial fibrillation (AF), the optimal treatment strategy for paroxysmal AF (PAF) remains unclear. Methods and Results A randomized, multicenter comparison of rate control vs rhythm control in Japanese patients with PAF(More)
Statins reduce cardiovascular morbidity and mortality from coronary artery disease (CAD). However, the effects of statin therapy in patients with CAD and chronic kidney disease (CKD) remain unclear. Within a single hospital-based cohort in the Shinken Database 2004–2010 comprising all patients (n = 15,227) who visited the Cardiovascular Institute, we(More)
Revascularization of an initially non-target site due to its progression as a new culprit lesion has emerged as a new therapeutic target of coronary artery disease (CAD) in the era of drug-eluting stents. Using the Shinken database, a single-hospital-based cohort, we aimed to clarify the incidence and prognostic factors for progression of previously(More)
To assess the maturation process of the cartilage after autologous chondrocyte implantation (ACI), we performed a longitudinal study with three-dimensional spoiled gradient-recalled (3D-SPGR) magnetic resonance imaging (MRI). Five knees of five patients on which ACI of the femoral condyle was performed were studied. The signal intensity of reparative tissue(More)
BACKGROUND Edoxaban is a once-daily (QD) oral, direct factor Xa inhibitor in clinical development for the prevention of stroke in patients with non-valvular atrial fibrillation (NVAF). The aim of this study was to evaluate the safety of edoxaban in Japanese patients with NVAF. METHODS AND RESULTS A total of 536 NVAF patients (CHADS2 ≥1) were randomized to(More)
BACKGROUND Oscillatory breathing, alternating between hyperpnea and hypopnea, has been recognized in cardiac patients, especially in those with heart failure. We evaluated whether the cycle length and amplitude of oscillatory breathing correlate with impaired cardiopulmonary function during exercise. METHODS AND RESULTS We analyzed respiratory gas data(More)
BACKGROUND A rapid heart rate (HR) during atrial fibrillation (AF) and atrial flutter (AFL) in left ventricular (LV) dysfunction often impairs cardiac performance. The J-Land study was conducted to compare the efficacy and safety of landiolol, an ultra-short-acting β-blocker, with those of digoxin for swift control of tachycardia in AF/AFL in patients with(More)
BACKGROUND Underuse and an inadequate range for the international normalized ratio (INR) for warfarin use are still problems in the management of the patients with atrial fibrillation (AF) in Japan. METHODS AND RESULTS From January to July 2009, a total of 7,937 AF patients [5,468 men (68.6 ± 10.0 years) and 2,469 women (72.2 ± 9.0 years)] were registered(More)
