A 74-year-old woman presented with effort-induced chest pain. Diagnostic coronary angiography revealed three-vessel disease. A successful angioplasty was performed with two sirolimus-eluting stents placed in the left anterior descending artery (LAD) and left circumflex artery (LCX). The right coronary artery (RCA) was treated with a bare-metal stent.(More)
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)
BACKGROUND  Epidemiology and clinical management of acute venous thromboembolism (VTE) are not readily available in Japan. METHODS AND RESULTS  The Japan VTE Treatment Registry (JAVA) is a multicenter cohort study of consecutive patients with an objectively confirmed, symptomatic acute pulmonary embolism (PE), symptomatic acute deep vein thrombosis (DVT),(More)
BACKGROUND Prasugrel is an antiplatelet agent that shows more prompt, potent, and consistent platelet inhibition than clopidogrel. The objective of this study was to confirm the efficacy and safety of prasugrel at loading/maintenance doses of 20/3.75 mg. METHODS AND RESULTS Japanese patients (n=1,363) with acute coronary syndrome undergoing percutaneous(More)
BACKGROUND Left ventricular function is the main predictor of long-term survival in patients with coronary artery disease. In patients with impaired left ventricular function after myocardial infarction, end-systolic volume is a better predictor than the global ejection fraction. We analyzed long-term follow-up of patients with impaired left ventricular(More)
In a double-blind trial of streptokinase for acute myocardial infarction, 219 consecutive patients presenting with infarction within four hours (mean, 3.0 +/- 0.8) of the onset of chest pain were randomly assigned to treatment with streptokinase (1.5 million units) or placebo, given intravenously over 30 minutes. The primary end point of the study was left(More)
A 65-year-old woman with hypertrophic obstructive cardiomyopathy presented with dyspnea. Transthoracic echocardiography showed severe mitral regurgitation (MR) due to systolic anterior motion and a peak gradient of 102 mmHg across the LV outflow. Cardiac magnetic resonance imaging (CMR) showed patchy late gadolinium enhancement in the hypertrophied septum.(More)
BACKGROUND Few studies have examined the effects of on-treatment platelet reactivity on the risk of major adverse cardiovascular events (MACE). We aimed to determine the optimal cutoff value of P2Y12 reaction units (PRUs) to prevent MACE occurring within 3days after percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS). METHODS We(More)
BACKGROUND Acute heart failure (AHF) is one of the most frequently encountered cardiovascular conditions that can seriously affect the patient's prognosis. However, the importance of early triage and treatment initiation in the setting of AHF has not been recognized. METHODS AND RESULTS The Tokyo Cardiac Care Unit Network Database prospectively collected(More)
Postsystolic shortening and thickening of ischemic and postischemic myocardium are well-recognized phenomena, but their significance is controversial. To discover whether postsystolic shortening and thickening might represent an active process and to establish their place as possible predictors of functional recovery during and after recovery from ischemia,(More)
