Management and Outcomes of Cardiac Sarcoidosis: Insights From the Nationwide MYSTICS Registry

Chisato Izumi, Yusuke Yoshikawa, Issei Komuro, Ken-ichi Hirata et autres

BACKGROUND: Cardiac sarcoidosis (CS) may lead to serious outcomes, but large-scale data are lacking because of its rarity, diagnostic uncertainty, and heterogeneous clinical presentations. Actual management and outcomes, including recurrence, are not well understood. This study aimed to clarify the actual management …

Long‐Term Vessel‐Oriented Outcomes After PCI in Routine Japanese Practice: A Retrospective Quantitative Flow Ratio Analysis With 2‐Year Landmark Evaluation

Shigetaka Kageyama, Daijiro Masunaga, Hirofumi Sugiyama, Michitomo Kawahito et autres

BACKGROUND: Post-PCI vessel quantitative flow ratio (QFR) and QFR virtual pullback (QVP) index reflect postprocedural physiological quality and the residual disease pattern after percutaneous coronary intervention (PCI), but their associations with very-long-term vessel-oriented composite endpoint (VOCE) remain uncertain. AIMS: We examined whether …

Serial Changes in Left Ventricular Ejection Fraction After Transcatheter Aortic Valve Implantation: Associations With Ischemic Heart Disease and Left Ventricular End‐Diastolic Diameter

Koji Tanaka, Shigetaka Kageyama, Hirofumi Sugiyama, Riho Sano et autres

PURPOSE: Left ventricular ejection fraction (LVEF) recovery after transcatheter aortic valve implantation (TAVI) varies among patients with severe aortic stenosis and reduced LVEF. We characterized serial changes in LVEF and examined their associations with ischemic heart disease (IHD) and baseline left ventricular …

A Bleeding Risk Score for Cancer-Associated Venous Thromboembolism in Patients Receiving Direct Oral Anticoagulants

Tomoyuki Nagai, Naohiko Nakanishi, Yugo Yamashita, Takeshi Morimoto et autres

BACKGROUND: Patients with cancer-associated venous thromboembolism (VTE) are at a high risk of major bleeding during anticoagulant therapy, emphasizing the need for bleeding risk assessment in the era of direct oral anticoagulants (DOACs). However, few bleeding risk scores have been specifically developed …

Clinical Outcomes of Anticoagulation Therapy With Direct Oral Anticoagulants or Warfarin in Patients With Atrial Fibrillation and Renal Impairment After Bioprosthetic Valve Replacement

Miwa Ito, Misa Takegami, Yutaka Furukawa, Makoto Miyake et autres

Background: Atrial fibrillation (AF) after bioprosthetic valve (BPV) replacement is common in older patients with multiple comorbidities and is associated with a heightened risk of thromboembolism. Anticoagulation therapy is often indicated, but renal impairment and other comorbidities elevate bleeding risk, making clinical …
