A simple method of sarcopenia detection can predict adverse cardiovascular events in patients with abdominal obesity.

Background: Although sarcopenic obesity is associated with a higher risk of cardiovascular events compared with obesity without sarcopenia, it is difficult to diagnose sarcopenia in daily clinical settings. Recently, a simple scoring system has been developed to identify sarcopenia patients based on three variables (age, hand grip strength, and calf circumference). However, the utility of this score for cardiovascular risk stratification in patients with abdominal obesity is unknown.

Prognostic significance of liver stiffness assessed by fibrosis-4 index in patients with heart failure.

Background: Heart failure (HF)-related congestive hepatopathy is a well-recognized problem in management of HF. The fibrosis-4 (FIB4) index calculated by [age × aspartate aminotransferase (IU/L)/platelet count (10 /L) × square root of alanine aminotransferase (IU/L)] is useful for evaluating liver stiffness. We aimed to investigate the impact of the FIB4 index on prognosis in patients with HF.

Association of early administration of furosemide with improved oxygenation in patients with acute heart failure.

Aims: Optimal pharmacological treatment for chronic heart failure has been established. However, treatments that can improve the prognosis of acute heart failure (AHF) are controversial. Although intravenous diuretics may be one optimal treatment option, little evidence has shown the effect of early administration of diuretics on clinical outcomes in patients with AHF.

Risk Prediction Score for Cancer Development in Patients With Acute Coronary Syndrome.

Background: Cancer is a known prognostic factor in patients with acute coronary syndrome (ACS), but few risk assessments of cancer development after ACS have been established.

Methods and results: Of the 573 consecutive ACS admissions between January 2015 and March 2018 in Nobeoka City, Japan, 552 were analyzed. Prevalent cancer was defined as a treatment history of cancer, and incident cancer as post-discharge cancer incidence.

Background: The impact of chronic kidney disease (CKD) on long-term outcomes following acute myocardial infarction (AMI) in the era of modern primary PCI with optimal medical therapy is still in debate.

Methods and results: A total of 3,281 patients with AMI were enrolled in the J-MINUET registry, with primary PCI of 93.1% in STEMI.

Development of anti-thrombotic vaccine against human S100A9 in rhesus monkey.

In post-stroke patients, a decreased adherence to antiplatelet drugs is a major challenge in the prevention of recurrent stroke. Previously, we reported an antiplatelet vaccine against S100A9 in mice, but the use of Freund's adjuvant and the difference in amino acid sequences in epitopes between mice and humans were problematic for clinical use. Here, we redesigned the S100A9 vaccine for the common sequence in both humans and monkeys and examined its effects in cynomolgus monkeys with Alum adjuvant.

A Coronary Artery-left Ventricular Fistula through the Sinusoid.

A 78-year-old woman was referred to our hospital because of repetitive suppurative arthritis at the artificial left knee joint. Her plasma brain natriuretic peptide level was 122 pg/mL. A 12-lead electrocardiogram showed a QS pattern in the inferior leads.

Cardiac computed tomography-derived extracellular volume fraction in late anthracycline-induced cardiotoxicity.

Cardiotoxicity in the late phase after anthracycline drugs administration remains to be defined. Of the 44 patients who received anthracycline treatment, 7 were found to have cancer therapeutics-related cardiac dysfunction (CTRCD). The global longitudinal strain determined by echocardiography and myocardial extracellular volume fraction (ECV) determined by cardiac computed tomography (CCT) of the CTRCD(+) group were significantly higher than those of the control group and CTRCD(-) group, whereas there were no significant differences between the control and CTRCD(-) groups.

Clinical characteristics and prognosis of patients with microvascular angina: an international and prospective cohort study by the Coronary Vasomotor Disorders International Study (COVADIS) Group.

Aims: To provide multi-national, multi-ethnic data on the clinical characteristics and prognosis of patients with microvascular angina (MVA).

Methods And Results: The Coronary Vasomotor Disorders International Study Group proposed the diagnostic criteria for MVA. We prospectively evaluated the clinical characteristics of patients according to these criteria and their prognosis.

Circulating Mature PCSK9 Level Predicts Diminished Response to Statin Therapy.

Background Statin-mediated efficacy of lowering low-density lipoprotein (LDL) cholesterol varies in each individual, and its diminished response is associated with worse outcomes. However, there is no established approach to predict hyporesponse to statins. PCSK9 (proprotein convertase subxilisin/kexin type 9) is a serine-protease associated with LDL metabolism, which circulates as mature and furin-cleaved PCSK9.

Long-Term Clinical Impact of Cardiogenic Shock and Heart Failure on Admission for Acute Myocardial Infarction.

Long-term clinical outcomes among patients with cardiogenic shock (CS) and heart failure (HF) who survive the early phase of acute myocardial infarction (AMI) remain uncertain. We investigated 3283 consecutive patients with AMI, selected from a prospective, nation-wide multicenter registry (J-MINUET) database comprising 28 institutions in Japan between July 2012 and March 2014. The 3263 eligible patients were divided into the following three groups: CS-/HF- group (n = 2467, 75.

The association between the extent of lipidic burden and delta-fractional flow reserve: analysis from coronary physiological and near-infrared spectroscopic measures.

Background: Vulnerable plaque features including lipidic plaque have been shown to affect fractional flow reserve (FFR). Given that formation and propagation of lipid plaque is accompanied by endothelial dysfunction which impairs vascular tone, the degree of lipidic burden may affect vasoreactivity during hyperemia, potentially leading to reduced FFR. Our aim is to elucidate the relationship of the extent of lipidic plaque burden with coronary physiological vasoreactivity measure.

Balloon pulmonary angioplasty in chronic thromboembolic pulmonary hypertension.

Chronic thromboembolic pulmonary hypertension (CTEPH) is caused by chronic stenosis or obstruction of the pulmonary arteries due to thromboembolism. Although previous studies have shown untreated CTEPH has a poor prognosis, the establishment of gold-standard therapies including pulmonary endarterectomy, balloon pulmonary angioplasty (BPA), and medical therapy has improved hemodynamics and right ventricular function, leading to good long-term survival. BPA is an important therapy for patients with inoperable CTEPH, although the procedure is currently limited to specific institutions and operators.

Validation of the atherothrombotic risk score for secondary prevention in patients with acute myocardial infarction: the J-MINUET study.

Thrombolysis in Myocardial Infarction Risk Score for Secondary Prevention (TRS2°P) is a contemporary risk scoring system for secondary prevention based on nine clinical factors. However, this scoring system has not been validated in other populations. The aim of this study was to validate the TRS2°P in patients with acute myocardial infarction (AMI) treated with primary percutaneous coronary intervention (PCI) in a nationwide registry cohort.

Current trends and future perspectives for heart failure treatment leveraging cGMP modifiers and the practical effector PKG.

Cyclic guanosine monophosphate (cGMP), an intracellular second messenger molecule synthesized by guanylated cyclases (GCs), controls various myocardial properties, including cell growth and survival, interstitial fibrosis, endothelial permeability, cardiac contractility, and cardiovascular remodeling. These processes are mediated by the main cGMP effector protein kinase G (PKG) activation of which exerts intrinsic protective responses against the adverse effects of neurohormonal stimulation and pathological cardiac stress. Therapeutic strategies that enhance cGMP levels and PKG activation have been used for heart failure, which can be executed by reducing natriuretic peptide (NP) proteolysis, enhancing cGMP synthesis, or blocking cGMP hydrolysis.

Validation of Acute Myocardial Infarction and Heart Failure Diagnoses in Hospitalized Patients With the Nationwide Claim-Based JROAD-DPC Database.

Big data systems such as diagnosis procedure combination (DPC) datasets have recently been used for research purposes. However, there have been few validation studies to determine the accuracy of diagnoses. The aim of this study was to validate and evaluate 2 diagnoses, namely acute myocardial infarction (AMI) and heart failure (HF), using International Classification of Diseases, 10th revision (ICD-10) codes in the Japanese Registry Of All cardiac and vascular Disease (JROAD)-DPC database.

Impact of Reactive Oxidative Metabolites Among New Categories of Nonischemic Heart Failure.

Background We investigated the clinical significance of derivatives of reactive oxygen metabolites (DROMs), a new marker of reactive oxygen species, in patients with nonischemic heart failure (HF) and compared them among new categories of HF. Methods and Results We recruited 201 consecutively hospitalized patients with HF and measured DROM under stable conditions. Then, we divided them according to new categories of HF (HF with reduced ejection fraction [EF], HF with midrangeEF, and HF with preserved EF) without coronary artery disease.

The feasibility and limitation of coronary computed tomographic angiography imaging to identify coronary lipid-rich atheroma in vivo: Findings from near-infrared spectroscopy analysis.

Background: Coronary computed tomography angiography (CCTA) non-invasively visualizes lipid-rich plaque. However, this ability is not fully validated in vivo. The current study aimed to elucidate the association of CCTA features with near-infrared spectroscopy-derived lipidic plaque measure in patients with coronary artery disease.
