BACKGROUND The relationship between major adverse cardiac events (MACE) and serum polyunsaturated fatty acid (PUFA) parameters has not been well documented in patients who have undergone percutaneous coronary intervention (PCI). The aim of the present study was to investigate this relationship. METHODS AND RESULTS A total of 284 consecutive patients who(More)
BACKGROUND We previously reported that the long-term luminal response after coronary bare metal stenting is triphasic, with an early restenosis phase spanning the 6 months after the index procedure, an intermediate-term regression phase from 6 months to 3 years, and a late renarrowing phase beyond 4 years. However, the clinical significance of late luminal(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 Stent fracture (SF) after drug-eluting stent implantation has recently become an important concern because of its potential association with in-stent restenosis and stent thrombosis. However, the incidence and clinical impact of SF after everolimus-eluting stent implantation remain unclear. METHODS AND RESULTS A total of 1035 patients with 1339(More)
OBJECTIVES Our aim was to study the relationships between total stent length (TSL) and long-term clinical outcomes after sirolimus-eluting stent (SES) implantation. BACKGROUND SES compared with bare-metal stent use for long lesion treatment is associated with reduced restenosis rates. METHODS Three-year follow-up data were available for 10,773 patients(More)
BACKGROUND Post-challenge hyperglycemia (PH) is well-established as one of risk factors for coronary artery disease. However, it remains unclear whether PH affects clinical outcomes in patients with stable angina undergoing percutaneous coronary intervention (PCI). METHODS A total of 828 patients with stable angina undergoing PCI were retrospectively(More)
Acute massive pulmonary embolism (PE) is a common life-threatening condition requiring emergent and suitable treatment. The aim of this study is to assess the efficacy and safety of local thrombolysis with a pulse-infusion-thrombolysis (PIT) catheter in the management of acute massive PE. Thirty-nine patients with PE were treated with catheter directed(More)
BACKGROUND Very late stent thrombosis (VLST) was reported to occur even in patients with bare metal stent (BMS) implantation, although the annual incidence of VLST after BMS was much lower than that after drug-eluting stent implantation. Pathophysiologic mechanisms of VLST after BMS implantation remain largely unknown. METHODS AND RESULTS From September(More)
BACKGROUND Early exercise after coronary stenting is considered to have a risk of stent thrombosis (ST). We investigate the safety of submaximal exercise training based on the Borg scale from the next day after coronary stenting. METHODS We enrolled 2351 patients who underwent successful coronary stenting. They were divided into early exercise training(More)
OBJECTIVES We aimed to see whether primary percutaneous coronary intervention (PCI) benefits for ST-segment elevation myocardial infarction (STEMI) in the aged could be validated. BACKGROUND Primary PCI benefits in elderly patients with STEMI remain uncertain. METHODS We reviewed 947 consecutive patients treated with primary PCI for STEMI: 331 were aged(More)
