BACKGROUND: The Total Thrombus-formation Analysis System 01 (T-TAS 01) is an advanced microchip-based device that enables quantitative assessment of blood thrombogenicity. However, broader clinical implementation remains limited by the lack of well-established reference intervals (RIs) in healthy, antithrombotic drug-naïve individuals. This study aimed to define RIs and identify clinical determinants of blood thrombogenicity in antithrombotic drug-naïve adults using T-TAS 01. METHODS: Blood thrombogenicity was measured using T-TAS 01 in 319 adults without antithrombotic therapy who underwent health checkups at the Miyakonojo Health Service Center. The T-TAS 01 parameters, PL18-AUC10 and AR10-AUC30, were calculated as the areas under the flow-pressure curves of the PL-chip (type I collagen-coated) and the AR-chip (type I collagen and tissue factor-coated), respectively. Their associations with clinical parameters were assessed using multivariate regression analysis. RESULTS: The median age was 46.0 years; 64.3% of participants were female, and 82.1% had no hypertension, dyslipidemia, or diabetes. The median platelet count was 247 × 109/L. The median PL18-AUC10 and AR10-AUC30 values were 392.3 and 1335.9, with RIs of 236.3 to 468.1 and 1010.0 to 1496.2, respectively. PL18-AUC10 was independently associated with white blood cell count (coefficient, 5.15; 95% CI, 0.88-9.41) and platelet count (0.36; 95% CI, 0.25-0.47), whereas AR10-AUC30 was independently associated with body mass index (4.06; 95% CI, 0.06-8.06), platelet count (0.79; 95% CI, 0.52-1.06), and γ-glutamyl transpeptidase (-0.54; 95% CI, -0.90 to -0.18). CONCLUSIONS: Our findings provide foundational reference data for the clinical application of T-TAS 01 and support its potential as a point-of-care tool for individualized assessment of thrombogenicity.

Transthyretin Val122Ile variant carriers are at risk of developing heart failure, with this variant being observed in individuals of Western African ancestry. We encountered three patients carrying this variant in a single kindred from southern Japan. The detection of amyloid in the carpal tunnel tissue prompted comprehensive clinical evaluation, confirming cardiac involvement. Speckle-tracking echocardiography and cardiac magnetic resonance imaging revealed age-related progression of myocardial involvement predominantly affecting the basal inferoseptum. The transthyretin Val122Ile variant is associated with poor clinical outcomes. Clinicians should be aware that this variant can also be sporadically present in elderly Japanese patients with cardiomyopathy or heart failure.

BACKGROUND: Although angiopoietin-like protein 3 (ANGPTL3) has emerged as a novel therapeutic target for lipid modulation, its prognostic significance in chronic coronary syndrome (CCS) remains unclear. This study aimed to evaluate the clinical determinants and prognostic value of circulating ANGPTL3 levels in patients with CCS. METHODS AND RESULTS: We prospectively enrolled 264 consecutive patients with CCS (median age 74 years; 73% male) undergoing cardiac catheterization. Serum ANGPTL3 levels were measured using an enzyme-linked immunosorbent assay. The primary endpoint was major adverse cardiovascular events (MACE). Female sex, elevated C-reactive protein and B-type natriuretic peptide, low high-density lipoprotein cholesterol levels, and absence of statin use were independently associated with higher ANGPTL3 levels. During follow up, 35 patients experienced MACE. In multivariable Cox regression models, ANGPTL3 remained an independent predictor of MACE. Receiver operating characteristic analysis identified 90.7 ng/mL as the optimal cut-off value for event discrimination. Kaplan-Meier curves demonstrated significantly higher event rates among patients with ANGPTL3 >90.7 ng/mL. In patients with CCS with low-density lipoprotein cholesterol (LDL-C) <70 mg/dL, elevated ANGPTL3 levels were also associated with increased MACE risk. CONCLUSIONS: Circulating ANGPTL3 levels independently predict adverse cardiovascular outcomes in CCS, including those in patients who achieve LDL-C targets, and may help identify residual cardiovascular risk not captured by traditional lipid parameters.

Abstract
Background
Coronary artery dissection during percutaneous coronary intervention (PCI) may lead to hemodynamic collapse. Intravascular ultrasound (IVUS)-guided tip detection–antegrade dissection re-entry (TD-ADR) may serve as a bailout strategy. We describe a unique case in which IVUS-guided TD-ADR successfully achieved true lumen re-entry after severe coronary dissection.
Case summary
A 64-year-old woman who had received long-term immunosuppressive therapy for rheumatoid arthritis was admitted for unstable angina. Subsequent evaluation revealed severe multivessel disease, and the patient underwent PCI of the left anterior descending artery (LAD). During the procedure, the patient experienced cardiac arrest, likely due to worsening global myocardial ischemia, and required venoarterial extracorporeal membrane oxygenation support. IVUS demonstrated subintimal wire tracking with true lumen collapse. IVUS-guided TD-ADR using a high-penetration chronic total occlusion wire supported by a microcatheter enabled precise re-entry into the true lumen and successful LAD revascularization. Severe left circumflex artery stenoses were also considered to perpetuate myocardial ischemia and hemodynamic instability, necessitating rescue PCI for hemodynamic stabilization. In addition, major bleeding complications due to guidewire-induced perforation of the right subclavian artery branch were managed using stenting and coil embolization. The patient recovered left ventricular function and was discharged in stable condition. During the 8-month follow-up after discharge, the patient was free of adverse events.
Discussion
This case highlights the feasibility of IVUS-guided TD-ADR as a bailout technique for coronary dissection during complex PCI. By enabling accurate true lumen re-entry, this approach facilitates timely revascularization and contributes to hemodynamic stabilization and recovery in a life-threatening setting.

糖尿病は疫学上動脈硬化性心血管疾患の強いリスク因子であるが、なぜリスク因子となるかは明らかでない。糖尿病性動脈硬化症の病態解明と病態に基づく動脈硬化進展予防スキームの構築を目的として、多層的な検証を進めている。大動脈瘤手術時に採取された動脈硬化病変組織を用いて以下の検討を行った。①病理学的解析、②キャピラリー電気泳動-飛行時間型質量分析計を用いた組織内代謝産物量の網羅的測定、③RNAマイクロアレイ解析及びRT-PCRを用いた遺伝子発現評価である。結果、早期病変から進行病変かけて量的に有意に変動する代謝産物・代謝関連遺伝子群を認め、中でも強い変動を認める代謝経路としてキヌレニン代謝を同定した。病理学的解析においてキヌレニン代謝関連酵素のマクロファージにおける発現を確認し、引き続きヒト末梢血単核球由来マクロファージを用いて、同酵素の機能解析実験を施行し、炎症病態との関連性を見出した。糖尿病 vs 非糖尿病患者から得られた血管病変の組織内代謝産物の量的比較を行ったが、糖尿病血管病変にて糖代謝経路の亢進を示唆する所見は認めなかった。以上の結果は、Journal of Atherosclerosis and Thrombosis (Nishimura et.al, 2020, Dec)に収載された。現在末梢血単核球から単球分画の単離工程の至適化を図り、引き続くフローサイトメトリー解析までのシンプルなワークフローを構築中である。末梢血単球を用いた糖代謝解析の臨床研究を本年度より開始すべく準備を進めている。
