There is a scarcity of data on clinical outcomes after intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) in patients with multivessel disease and chronic kidney disease (CKD). The OPTIVUS-Complex PCI study multivessel cohort was a prospective multicenter single-arm trial enrolling 1015 patients who underwent multivessel IVUS-guided PCI including left anterior descending coronary artery target with an intention to meet the prespecified OPTIVUS criteria for optimal stent expansion. We compared the clinical outcomes between patients with and without CKD.

Unlabelled: A 70-year-old man was referred to our hospital with a diagnosis of progressive increase in extravasation leading to an iatrogenic coronary artery (CA) pseudoaneurysm within a month of percutaneous coronary intervention (PCI). The pseudoaneurysm was located on the carina side of the proximal left descending artery (LAD) accompanied by peri-stent contrast staining around the left main trunk (LMT). After a shared decision-making process, a second PCI was performed to prevent CA pseudoaneurysm rupture owing to concerns of adhesion around the LMT and difficulty in approaching the carina side of the proximal LAD for surgery.

Methods And Results: We enrolled 340 consecutive patients with ACS who were transported by EMS within 12 h of symptom onset. According to Japanese Circulation Society guidelines, CS-ACS (n=48) was diagnosed with or without a pharmacological provocation test (n=34 and n=14, respectively).
Background: The clinical benefits of optical frequency domain imaging (OFDI)-guided percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS) remain unclear.
Aims: We sought to compare intravascular ultrasound (IVUS)- and OFDI-guided PCI in patients with ACS.
Methods: OPINION ACS is a multicentre, prospective, randomised, non-inferiority trial that compared OFDI-guided PCI with IVUS-guided PCI using current-generation drug-eluting stents in ACS patients (n=158).
Background: The benefit of prehospital 12‑lead electrocardiogram (PH-ECG) performed by emergency medical service personnel at the site of first medical contact (FMC) in patients with ST-segment elevation myocardial infarction (STEMI) with cardiogenic shock (CS-STEMI) remains unclear. This study aimed to investigate the effect of PH-ECG on door-to-device time in patients with CS-STEMI.
Methods: This study enrolled CS-STEMI (Killip class IV) patients who were transferred directly to hospitals by ambulance (n = 517) from the Kanagawa Acute Cardiovascular Registry database.
Background: This study aimed to systematically evaluate voice symptoms during heart failure (HF) treatments and to exploratorily extract HF-related vocal biomarkers.
Methods And Results: This single-center, prospective study longitudinally acquired 839 audio files from 59 patients with acute decompensated HF. Patients' voices were analyzed along with conventional HF indicators (New York Heart Association [NYHA] class, presence of pulmonary congestion and pleural effusion on chest X-ray, and B-type natriuretic peptide [BNP]) and GOKAN scores based on the assessment of a cardiologist.
Background: The prognostic implications of persistent low-grade inflammation in patients with chronic coronary syndrome (CCS) are underexplored. The REAL-CAD (Randomized Evaluation of Aggressive or Moderate Lipid Lowering Therapy with Pitavastatin in Coronary Artery Disease) study demonstrated the benefit of higher intensity pitavastatin in Japanese patients with CCS.
Objectives: This prespecified subanalysis of the REAL-CAD study aimed to assess the prognostic effect of the persistent low-grade inflammation represented by high-sensitivity C-reactive protein (hs-CRP) in CCS patients.
Percutaneous coronary intervention for left main coronary artery disease (LM-PCI) represents a high-risk yet life-saving procedure that has evolved significantly over the years. This review outlines the current state-of-the-art practices for LM-PCI in Japan in detail, emphasizing the integration of coronary physiology and intracoronary imaging alongside with evidence-based standardized technique using latest drug-eluting stents. These advancements enable precise lesion assessment, stent sizing, and optimal deployment, thereby enhancing procedural safety and efficacy.

The purpose of this study is to determine the frequency and clinical characteristics of cardiac amyloidosis latent in AF by performing cardiac magnetic resonance imaging (MRI) in patients scheduled for AF ablation. We retrospectively analyzed 193 consecutive patients who underwent CA and cardiac MRI for atrial fibrillation.

Background: Weight loss is a poor prognostic factor in patients with chronic heart failure (HF). However, whether the same is true for hospitalized patients with HF is unknown, even though hospitalization is the first opportunity for many patients to be diagnosed with HF. This study aimed to investigate the prognostic value of weight loss in patients hospitalized for HF.

This single-center, retrospective study explored LDL-C trajectory after ACS and its associations with subsequent cardiovascular events (CVE).
Methods: In 831 patients with ACS, we evaluated LDL-C reduction during the first 2 months post-ACS as an index of early intervention and the area over the curve for LDL-C using 70 mg/dl as the threshold in the next 6 months (AOC-70) as a persistent intensity index.
Background: The comparative efficacy and safety of adjusted- and standard-dose prasugrel in East Asian patients with acute myocardial infarction (AMI) undergoing percutaneous coronary intervention (PCI) remain unclear. This study aimed to comparatively assess the ischaemic and bleeding outcomes of adjusted-dose (maintenance dose: 3.75 mg) and standard-dose (maintenance dose: 10 mg) prasugrel in East Asian patients with AMI undergoing PCI.

The Optimal Intravascular Ultrasound Guided Complex Percutaneous Coronary Intervention study multivessel cohort was a prospective, multicenter, single-arm trial enrolling 1,021 patients who underwent multivessel PCI, including left anterior descending coronary artery using IVUS, aiming to meet the prespecified OPTIVUS criteria for optimal stent expansion. We compared the clinical outcomes between those patients with and without diabetes.

This study aimed to (i) determine the incidence of heart failure admission among AMI survivors, (ii) compare 1 year outcomes between patients with heart failure admission and those without, and (iii) identify the independent risk factors associated with heart failure admission.
Methods And Results: The Japan Acute Myocardial Infarction Registry is a prospective multicentre registry from which data on consecutively enrolled patients with AMI from 50 institutions between 2015 and 2017 were obtained.
Background: A delayed and recurrent complete atrioventricular block (CAVB) is a life-threatening complication of transcatheter aortic valve replacement (TAVR). Post-TAVR evaluation may be important in predicting delayed and recurrent CAVB requiring permanent pacemaker implantation (PPI). The impact of new-onset right bundle-branch block (RBBB) after TAVR on PPI remains unknown.
