Association between J-CTO score and long-term target lesion revascularization rate after successful chronic total coronary occlusion angioplasty (from the J-CTO Registry).

Objectives: The aim of this study was to evaluate the impact of the J-CTO score on long-term target lesion revascularization (TLR) after successful native chronic total occlusion (CTO)-percutaneous coronary intervention (PCI).

Background: We previously reported that the J-CTO score could be used to stratify the lesion complexity and procedural success rate in CTO lesions.

Methods: We evaluated the prognostic significance of a high J-CTO score for long-term TLR rate in the J-CTO Registry.

Does Treatment of Impaired Glucose Tolerance Improve Cardiovascular Outcomes in Patients with Previous Myocardial Infarction?

Purpose: We evaluated the effects of an alpha-glucosidase inhibitor, voglibose, on cardiovascular events in patients with a previous myocardial infarction (MI) and impaired glucose tolerance (IGT).

Methods: This prospective, randomized, open, blinded-endpoint study was conducted in 112 hospitals and clinics in Japan in 3000 subjects with both previous MI and IGT receiving voglibose (0.6 mg/day, n = 424) or no drugs (n = 435) for 2 years.

Puberty, ovarian cycle, pregnancy, and postpartum ovulation in captive Sichuan golden monkeys (Rhinopithecus roxellana) based on changes in urinary and fecal gonadal steroid metabolites.

The purpose of this study was to evaluate the reproductive status and clarify the reproductive physiology of captive Sichuan golden monkeys. The concentrations of urinary estradiol-3-glucuronide (EG) and pregnanediol-glucuronide (PdG) or fecal estradiol-17β (E) and PdG in two females, and fecal testosterone concentrations in a male, were measured continuously using enzyme immunoassays. On the basis of these hormone profiles, the follicular phase, luteal phase, and ovarian cycle were calculated to be 14.

Intrauterine insemination with fresh semen in Amur leopard cat (Pionailurus bengalensis eutilura) during non-breeding season.

Equine and human chorionic gonadotropins were administered to two female Amur leopard cats to induce estrus and ovulation during non-breeding season. Fresh semen collected from male cats was surgically inseminated into the uterine horn of the females. In one animal, two fetal sacs without heartbeats were observed on abdominal ultrasonography 31 days after insemination, which indicated that embryo death had occurred.

Impact of J-CTO score on procedural outcome and target lesion revascularisation after percutaneous coronary intervention for chronic total occlusion: a substudy of the J-CTO Registry (Multicentre CTO Registry in Japan).

Aims: We investigated the impact of the J-CTO score, a pre-procedural risk score for successful guidewire crossing within 30 minutes through chronic total occlusion (CTO) lesions, on procedural and midterm clinical outcomes in terms of target lesion revascularisation (TLR) after CTO recanalisation.

Methods And Results: The primary endpoint of this substudy was midterm TLR. The net midterm success rate was calculated by multiplying the lesion success rate by the TLR-free survival rate.
