Comparing moderate-severe and severe mitral regurgitation in transcatheter aortic valve replacement on 1-year survival: insights from a Japanese Nationwide Registry.

This study aims to compare 1-year outcomes after transcatheter aortic valve replacement (TAVR) between patients with moderate-severe MR and severe MR preoperatively using the Japan Transcatheter Valve Therapy (J-TVT) registry. Patients undergoing TAVR for aortic stenosis between August 2013 and December 2019 with preoperative mitral regurgitation of moderate-severe (group MR3) or severe (group MR4) were included. Patients with a history of valve surgery and dialysis patients were excluded.

Patterns and Prognostic Impact of Post-Discharge Ischemic, Bleeding, and Heart Failure Events After Myocardial Infarction.

Although the in-hospital prognosis after acute myocardial infarction (AMI) has considerably improved to date, ischemic, bleeding, and heart failure (HF) events after discharge remain clinical challenges. However, the pattern of such events is not fully understood in contemporary clinical practice. The present study aimed to evaluate the timing and prognostic impact of cardiovascular and bleeding events after AMI.

Impact of the Stress Hyperglycemia Ratio on Heart Failure and Atherosclerotic Cardiovascular Events After Acute Myocardial Infarction.

Background: An acute hyperglycemic status is reportedly associated with poor prognosis in patients with acute cardiovascular diseases. Although the stress hyperglycemia ratio (SHR) is used to evaluate the hyperglycemic condition on admission, relationships between SHR and clinical outcomes, particularly heart failure (HF), remain uncertain in acute myocardial infarction (AMI).

Methods And Results: This retrospective multicenter study included 2,386 patients with AMI undergoing percutaneous coronary intervention.

Combined assessment of fractional flow reserve, resting full-cycle ratio, and resting ratio of distal coronary to aortic pressure for clinical outcomes.

Background: Fractional flow reserve (FFR) and non-hyperemic indices are invasive standards for evaluating functional significance of coronary stenosis. However, data are limited about outcomes in vessels with concordant and discordant physiological results, particularly with a ratio of distal coronary to aortic pressure (Pd/Pa) at rest.

Methods: This was a single-center, retrospective, observational study.

Impact of Cancer, Inflammation, and No Standard Risk Factors in Patients With Myocardial Infarction.

Background: The lack of standard modifiable cardiovascular risk factors (SMuRFs), including hypertension, diabetes, dyslipidemia, and smoking, is reportedly associated with poor outcomes in acute myocardial infarction (AMI). Among patients with no SMuRFs, cancer and chronic systemic inflammatory diseases (CSIDs) may be major etiologies of AMI.

Objectives: The purpose of this study was to evaluate clinical characteristics and outcomes of patients with cancer, CSIDs, and no SMuRFs in AMI.

Differential Prognostic Impact of Risk-Prediction Models for Heart Failure in Acute Myocardial Infarction: The Original and Revised Heart Failure Time-Points.

We previously developed a risk-scoring system for heart failure (HF) in patients with acute myocardial infarction (MI), namely "HF time-points (HFTPs)". In the original HFTPs, the presence of HF on admission, during hospitalization, and at short-term follow-up was individually scored. This study examined whether the revised HFTPs, with additional scoring of previous HF, provide better predictivity.

Diagnostic Ability of Manual Calcification Length Assessment on Non-Electrocardiographically Gated Computed Tomography for Estimating the Presence of Coronary Artery Disease.

Coronary artery calcification score (CACS) on electrocardiography (ECG)-gated computed tomography (CT) is used for risk stratification of atherosclerotic cardiovascular disease, which requires dedicated analytic software. In this study, we evaluated the diagnostic ability of manual calcification length assessment on non-ECG-gated CT for epicardial coronary artery disease (CAD). A total of 100 patients undergoing both non-ECG-gated plain CT scans with a slice interval of 1.

Relation of Vasoreactivity in the Left and Right Coronary Arteries During Acetylcholine Spasm Provocation Testing.

The diagnosis of vasospastic angina (VSA) according to Japanese guidelines involves an initial intracoronary acetylcholine (ACh) provocation test in the left coronary artery (LCA) followed by testing in the right coronary artery (RCA). However, global variations in test protocols often lead to the omission of ACh provocation in the RCA, potentially resulting in the underdiagnosis of VSA. This study assessed the validity of the LCA-only ACh provocation approach for the VSA diagnosis and whether vasoreactivity in the LCA aids in determining further provocation in the RCA.

Prognosis of anemic patients with atrial fibrillation undergoing percutaneous coronary intervention.

Background: There are limited data regarding whether anemia is associated with adverse clinical outcomes in patients with atrial fibrillation (AF) after percutaneous coronary intervention (PCI).

Methods: Patients with AF undergoing PCI at 15 institutions between January 2015 and March 2021 were included in this analysis. Based on the baseline hemoglobin levels, moderate to severe anemia was defined as hemoglobin levels <11 g/dL, and mild anemia was defined as hemoglobin levels 11-12.

Prognostic Impact of Previous Atherosclerotic Cardiovascular Disease on Short- and Long-Term Outcomes in Acute Myocardial Infarction.

Patients with previous atherosclerotic cardiovascular disease (ASCVD) are typically managed by secondary prevention modalities; however, they may experience recurrent events. In acute myocardial infarction (MI), the prognostic effect of preexisting ASCVD on the short- and long-term outcomes remains uncertain. This retrospective, multicenter registry included 2,475 patients with acute MI who underwent percutaneous coronary intervention.

Thrombolysis in Myocardial Infarction Frame Count for Coronary Blood Flow Evaluation during Interventional Diagnostic Procedures.

: An interventional diagnostic procedure (IDP), including intracoronary acetylcholine (ACh) provocation and coronary physiological testing, is recommended as an invasive diagnostic standard for patients suspected of ischemia with no obstructive coronary arteries (INOCA). Recent guidelines suggest Thrombolysis In Myocardial Infarction frame count (TFC) as an alternative to wire-based coronary physiological indices for diagnosing coronary microvascular dysfunction. We evaluated trajectories of TFC during IDP and the impact of ACh provocation on TFC.

Regional variation in the use of revascularisation for peripheral artery disease in Japan: a cross-sectional observational study.

Objectives: We aimed to investigate the regional variations in the number of interventions and surgeries for peripheral artery disease (PAD) and explore the major determinants of the variations.

Design: Cross-sectional study.

Setting: The Japanese Ministry of Health, Labour and Welfare National Database and Diagnostic Procedure Combination database in 2018.

Relation of Thrombolysis in Myocardial Infarction Frame Count to Invasively Measured Coronary Physiologic Indexes.

In the international guidelines, higher thrombolysis in myocardial infarction frame count (TFC) is indicated as evidence of coronary microvascular dysfunction (CMD). However, the association of TFC with invasively measured coronary physiologic parameters such as coronary flow reserve (CFR) and index of microcirculatory resistance (IMR) remains unclear. Patients without significant epicardial coronary lesions underwent invasive coronary physiologic assessment using a thermodilution method in the left anterior descending artery.

Correction: Comparison of short-term clinical outcomes between low-dose prasugrel and clopidogrel as part of triple antithrombotic therapy in patients requiring oral anticoagulant therapy and percutaneous coronary intervention.

Coronary Artery Perforation After Balloon Dilatation for Recurrent In-Stent Restenosis Inside the Double-Layered Previous Stents.

Although coronary artery perforation can be a fatal complication during percutaneous coronary intervention, it is rarely observed in in-stent restenotic lesions. We present a case with coronary artery perforation after balloon dilatation for a recurrent in-stent restenotic lesion with calcified nodule inside the double-layered stents that were previously implanted. ().

Clinical characteristics and outcomes of patients with chronic systemic inflammatory disease in acute myocardial infarction.

Background: Chronic systemic inflammatory diseases (CSIDs) such as rheumatoid arthritis (RA) are reportedly associated with an increased risk of ischemic cardiovascular events including acute myocardial infarction (MI). However, data are limited on clinical characteristics and ischemic and bleeding outcomes after acute MI in patients with CSIDs.

Methods: This bi-center registry included a total of 1001 patients with acute MI undergoing percutaneous coronary intervention.

Diagnostic ability of Japanese version of high bleeding risk criteria for ischemic outcomes in patients with acute myocardial infarction.

The Japanese version of high bleeding risk (J-HBR) criteria was domestically proposed to identify patients at HBR after percutaneous coronary intervention (PCI). The applicability of J-HBR on bleeding events has been validated, while whether J-HBR predicts ischemic events is uncertain. This bi-center registry included 904 patients with acute myocardial infarction (MI) undergoing primary PCI.
