BACKGROUND Although coronary stents have been proved effective in reducing clinical cardiac events for up to 3 to 5 years, longer term clinical and angiographic outcomes have not yet been fully clarified. METHODS AND RESULTS To evaluate longer term (7 to 11 years) outcome, clinical and angiographic follow-up information was analyzed in 405 patients with(More)
BACKGROUND The predictive value of T-wave alternans (TWA) for lethal ventricular tachyarrhythmia in patients with left ventricular (LV) dysfunction is controversial. Also, long-term arrhythmia risk of patients ineligible for the TWA test is unknown. METHODS This was a multicenter, prospective observational study of patients with LV ejection fraction ≤40%(More)
AIMS Substantial portion of early arrhythmia recurrence after catheter ablation for atrial fibrillation (AF) is considered to be due to irritability in left atrium (LA) from the ablation procedure. We sought to evaluate whether 90-day use of antiarrhythmic drug (AAD) following AF ablation could reduce the incidence of early arrhythmia recurrence and thereby(More)
Relation of antiplatelet therapy (APT) discontinuation with the risk of serious cardiovascular events has not been fully addressed yet. This study is aimed to evaluate the risk of ischemic event after APT discontinuation based on long-term APT status of large cohort. In the CREDO-Kyoto Registry Cohort-2 enrolling 15939 consecutive patients undergoing first(More)
AIMS Most of recurrent atrial tachyarrhythmias after pulmonary vein isolation (PVI) for atrial fibrillation (AF) are due to reconnection of PVs. The aim of the present study was to evaluate whether elimination of adenosine triphosphate (ATP)-induced dormant PV conduction by additional energy applications during the first ablation procedure could reduce the(More)
BACKGROUND Observational registries comparing coronary artery bypass graft (CABG) surgery and percutaneous coronary intervention (PCI) have reported long-term survival results that are discordant with those of randomized trials. METHODS AND RESULTS We conducted a multicenter study in Japan enrolling consecutive patients undergoing first CABG or PCI(More)
Addition of clopidogrel to aspirin and fibrinolytic therapy for myo-cardial infarction with ST-segment elevation. Effect of clopi-dogrel pretreatment before percutaneous coronary intervention in patients with ST-elevation myocardial infarction. The PCI-CLARITY Study. Senges J, for the ACOS Study Group. Different treatments and outcomes of consecutive(More)
BACKGROUND There still remain safety concerns on surgical procedures after coronary drug-eluting stents (DES) implantation, and optimal management of perioperative antiplatelet therapy (APT) has not been yet established. METHODS AND RESULTS During 3-year follow-up of 12 207 patients (DES=6802 patients and bare-metal stent [BMS] only=5405 patients) who(More)
BACKGROUND Catheter ablation is a non-medication therapy for atrial fibrillation, and during the procedure, warfarin is withdrawn in the preoperative period to prevent the risk of bleeding. In case of emergency, vitamin K2 can be intravenously administered to antagonize the anticoagulant activity of warfarin. The aims of this study were to conduct(More)
