Cathelicidin Links Visceral Fat Accumulation and Coronary Artery Disease

Motoki Taniguchi, Akira Taruya, Chie Kitahara, Shingo Ota et autres

BACKGROUND: Visceral fat (VF), particularly epicardial adipose tissue (EAT), plays a crucial role in the development of coronary artery disease (CAD). Cathelicidin (LL37) is an antimicrobial peptide involved in innate immunity and has been implicated in inflammatory processes. However, the relationship between …

Evaluation of Intercaval Bundle Connection by Multisite Pacing and Right-Sided Pulmonary Vein Isolation

Manabu Kashiwagi, Akio Kuroi, Daichi Miyake, Yusuke Teruya et autres

BACKGROUND: An intercaval bundle connection (IBC) between the right pulmonary vein (PV) and the right atrium (RA) reduces PV isolation success, but the epidemiology requires elucidation. OBJECTIVES: The authors investigated the frequency and distribution of IBC diagnosed by multisite pacing and its …

Intrapericardial Chronic Expanding Hematoma Causing Myocardial Ischemia by Compressing the Left Anterior Descending Artery

Motoki Taniguchi, Yasutsugu Shiono, Kanako Sagan, Shingo Ota et autres

BACKGROUND: Intrapericardial chronic expanding hematoma (CEH) is rare, but the diagnosis is challenging because it should be differentiated from cardiac tumors and can cause unique consequences. CASE SUMMARY: An 80-year-old woman with a history of chest trauma presented with exertional dyspnea. Computed …

Thresholds of invasive physiological indices associated with angina and limited exercise capacity in patients with chronic coronary syndrome: SYMPTOM registry

Natsuki Higashimoto, Y Shiono, D Higashioka, Hiroki Emori et autres

Abstract Background While the thresholds of fractional flow reserve (FFR) and non-pressure hyperaemic ratios (NHPR) for identifying myocardial ischemia (≤0.75 for FFR, ≤0.89 for NHPR) and guiding coronary revascularization (≤0.80 for FFR, ≤0.89 for NHPR) are well established, the values associated with …

Effect of Esaxerenone in Patients With Persistent Atrial Fibrillation and Hypertension After Catheter Ablation

Manabu Kashiwagi, Akio Kuroi, Natsuki Higashimoto, Satoshi Hata et autres

Background In this study, we investigated the effects of esaxerenone, a nonsteroidal mineralocorticoid receptor antagonist, in patients with persistent atrial fibrillation (AF) and hypertension after they had undergone catheter ablation. Methodology Our retrospective analysis included 157 consecutive patients with this condition. Overall, …

Combined Minimally Invasive Surgical and Percutaneous Approaches for a Patient on Hemodialysis With Severe Aortic Stenosis and Complex Coronary Artery Disease

Teruaki Wada, Kentaro Honda, Hironori Kitabata, Yoshiharu Nishimura et autres

Patients on hemodialysis with concomitant severe aortic stenosis (AS) and multivessel coronary artery disease (CAD) are at high risk for surgical aortic valve replacement (SAVR) and coronary artery bypass grafting (CABG). Transsubclavian–transcatheter aortic valve implantation (TSc‐TAVI) is a well‐established alternative approach to …

Coronary flow characteristics in cases with discordance between coronary flow reserve and the index of microvascular resistance in the assessment of coronary microvascular dysfunction

Yasutsugu Shiono, Misako Taniguchi, Jiro Takeda, R. S. Hikida et autres

Abstract Background/Introduction Coronary flow reserve (CFR) and the index of microvascular resistance (IMR) are commonly used for the diagnosis of coronary microvascular dysfunction, but the two indices can reveal discordance. Purpose The aim of this study was to investigate the mechanisms of …
