Limited data exists on ST-segment elevation myocardial infarction (STEMI) and non-STEMI (NSTEMI) managed by a well-organized cardiac care network in a metropolitan area. We analyzed the Tokyo CCU network database in 2009-2010. Of 4329 acute myocardial infarction (AMI) patients including STEMI (n = 3202) and NSTEMI (n = 1127), percutaneous coronary(More)
OBJECTIVES Although B-type natriuretic peptide (BNP) and highly sensitive cardiac troponin T (cTnT) are useful for the evaluation of clinical features in various cardiovascular diseases, there are comparatively few data regarding the utility of these parameters in patients with hypertrophic obstructive cardiomyopathy (HOCM). The goal of this study was to(More)
BACKGROUND  The prognostic value of late gadolinium enhancement (LGE) on contrast-enhanced cardiovascular magnetic resonance (CMR) in Japanese hypertrophic cardiomyopathy (HCM) patients in a large, single-center cohort was investigated. METHODS AND RESULTS  A total of 345 HCM patients (mean age, 59±17 years; 214 male) underwent CMR with gadolinium(More)
of left ventricular hypertrophy after surgical therapy for aortic stenosis is associated with changes in extracellular matrix gene expression. Left ven-tricular myocardial structure in aortic valve disease before, intermediate, and late after aortic valve replacement. Regression of myocardial hyper-trophy in aortic valve disease following aortic valve(More)
AIMS There seems to be two distinct patterns in the presentation of acute heart failure (AHF) patients; early- vs. gradual-onset. However, whether time-dependent relationship exists in outcomes of patients with AHF remains unclear. METHODS The Tokyo Cardiac Care Unit Network Database prospectively collects information of emergency admissions via EMS(More)
Transcatheter aortic valve implantation (TAVI) is an expanding procedure. One of the risks associated with the procedure is coronary obstruction. An 85-year-old woman was referred to our institute to be scheduled for TAVI. Multidetector three-dimensional (3D) computed tomography was performed. The left coronary height was 13.3 mm from the annulus ring(More)
BACKGROUND The clinical features of gender differences in takotsubo cardiomyopathy (TC) remain to be determined. The aim of this study was to evaluate the differences in clinical characteristics of male and female patients with TC. METHODS We obtained the clinical information of 368 patients diagnosed with TC (84 male, 284 female) from the Tokyo CCU(More)
An 86-year-old woman had been referred to our institution for alcohol septal ablation (ASA) because of drug-refractory hypertrophic obstructive cardiomyopathy. The resting pressure gradient of the left ventricular outflow tract was 135 mmHg on echocardiography. After an over-the-wire balloon (Apex OTW w ; 1.5/8 mm; Boston Scientific) was inflated in the(More)
To determine the mechanical factors affecting regional segmental motion after acute coronary occlusion, we studied seven conscious dogs, instrumented with sonomicrometers. Loading conditions were changed by the withdrawal of 500 ml of blood and the transfusion of 800 ml of blood. To express segmental motion, percent systolic shortening, percent systolic(More)
