Successful or Uncomplicated Use of Drug‐Coated Balloon Versus Drug‐Eluting Stent Strategies for De Novo Culprit Lesions in Acute Coronary Syndromes: Insights from a Nationwide Registry in Japan Open
Background Randomized trials demonstrated that drug‐coated balloon (DCB) was not inferior to drug‐eluting stent (DES) for acute coronary syndrome (ACS). However, generalizability in clinical settings remains unclear. The present study comp…

Diastolic Mitral Regurgitation Caused by Acute Myocardial Infarction Complicated With Severe Heart Failure Open
Diastolic mitral regurgitation (MR) is a rare and often-overlooked form of functional MR. Key factors in the development of diastolic MR include incomplete closure of the mitral valve, reversal of left atrioventricular pressure gradient du…

Association between the Atherosclerotic Modifiable Risk Factor Burden and Coronary Inflammation Open
A greater RF burden was associated with increased coronary inflammation in a dose-dependent manner. These findings indicate that RF clustering is associated with higher coronary inflammation even in the absence of significant coronary plaq…

Influence of pathophysiological patterns of coronary artery disease on the safety and efficacy of percutaneous coronary intervention Open
Background Impaired blood flow after PCI, reflected by low FFR, portends a worse prognosis. Prior to intervention, pressure gradient distributions offer insights into the likelihood of subsequent PCI success. The pullback pressure gradient…
View article: Impact of systolic coronary flow reversal in patients with aortic stenosis: assessment with transthoracic echocardiography
Impact of systolic coronary flow reversal in patients with aortic stenosis: assessment with transthoracic echocardiography Open
Background In patients with aortic stenosis (AS), increased systolic wall stress due to increased afterload reduces systolic coronary flow, often leading to systolic coronary flow reversal (SFR) in epicardial coronary arteries. Purpose We …

Clinical outcomes of percutaneous coronary intervention for severely calcified lesions: comparison between the morphologies of severely calcified coronary lesions Open
Existing studies evaluating the comparison of clinical outcome of percutaneous coronary intervention (PCI) for severe calcified coronary lesions are limited, and the clinical outcomes of PCI for different morphologies of calcified lesions …

Predictors of Hypotension After Angiotensin Receptor-Neprilysin Inhibitor Administration in Patients with Heart Failure Open
Angiotensin receptor-neprilysin inhibitors (ARNI) are effective against heart failure (HF) with reduced ejection fraction, but hypotension is a significant complication. Predictors of ARNI-associated hypotension remain unclear. This study …

Impact of Antiplatelet Therapy on 5-Year Outcomes After Fractional Flow Reserve-Guided Deferral of Revascularization in Nonsignificant Obstructive Coronary Artery Disease Open
The 5-year outcomes after FFR-guided deferral of revascularization did not significantly differ between the APT and non-APT groups, suggesting that APT might not be a critical requirement for nonsignificant obstructive CAD patients not req…
