OBJECTIVES: Abnormal glucose tolerance in patients with acute myocardial infarction (AMI) is associated with greater mortality and adverse cardiovascular effects. As statins possess a range of beneficial pleiotropic effects on the cardiovascular system, we sought to assess the cardioprotective effects of statins on left ventricular function in patients with AMI in relation to glycometabolic state. METHODS: In a prospective, randomized trial, 140 patients with AMI were randomized to intensive statin therapy receiving statin loading with 80 mg of rosuvastatin followed by 40 mg daily or standard statin therapy...

Brugada syndrome is a primary arrhythmic syndrome that accounts for 20% of all sudden cardiac death cases in individuals with a structurally normal heart. Pathogenic variants associated with Brugada syndrome have been identified in over 19 genes, with SCN5A as a pivotal gene accounting for nearly 30% of cases. In contrast to other arrhythmogenic channelopathies (such as long QT syndrome), digenic inheritance has never been reported in Brugada syndrome. Exploring 66 cardiac genes using a new custom next-generation sequencing panel, we identified a double heterozygosity for pathogenic mutations in SCN5A and TRPM4 in a Brugada syndrome patient...

OBJECTIVE: To evaluate endothelial progenitor cells (EPCs) and systemic microvascular function in patients with severe hypercholesterolemia, comparing patients with the definite familial hypercholesterolemia (FH) phenotype (DFH) or probable/possible FH phenotype (PFH). There is a large spectrum of atherosclerotic disease between these two clinical phenotypes of FH, and to acquire further knowledge of the pathophysiology of vascular disease in both is desirable. METHODS: Subjects with severe hypercholesterolemia, defined as low-density lipoprotein cholesterol (LDL-C) >190 mg/dL, were classified as DFH or PFH and underwent measurement of the number of EPCs by flow cytometry and evaluation of cutaneous microvascular reactivity using a laser speckle contrast-imaging system with iontophoresis of acethylcholine (ACh) or sodium nitroprusside...

OBJECTIVES: Retropharyngeal lesions are often associated with Kawasaki disease (KD). A 4-year-old male first presented a peritonsillar and retropharyngeal abscess-like lesion. Surgical tonsillectomy was performed to avoid a risk of mediastinal abscess, but he fulfilled the diagnostic criteria of KD after the operation. This prompted us to perform a histological study on the KD tonsils. METHODS: The histopathology of the KD tonsil specimens were compared with hypertrophic tonsils obtained from 4 patients with chronic tonsillitis unrelated to KD assessed by the immunostainings...

BACKGROUND: The N-terminal fragment of the prohormone brain-type natriuretic peptide (NT-proBNP) is a powerful predictor of adverse outcomes in patients with coronary artery disease (CAD). However, little is known regarding the prognostic significance of longitudinal changes in NT-proBNP levels. METHODS: We evaluated the ability of 5-year changes in NT-proBNP levels to predict subsequent heart failure (HF) hospitalization or cardiovascular (CV) death in 635 participants with stable CAD enrolled in the Heart and Soul Study...

OBJECTIVE: Limited data is available on the long-term outcome of patients with increased cardiovascular event risk, treated with newer-generation durable polymer drug-eluting stents (DES). METHODS: We therefore assessed 3-year follow-up data of high-risk versus low- to intermediate-risk patients of the randomized DUTCH PEERS trial (NCT01331707). In both risk groups we also compared patients treated with Resolute Integrity versus Promus Element DES. Patients were categorized as "high-risk" if they met ≥1 of the following criteria: (1) diabetes (17...

OBJECTIVE: Cardiomyopathy (CMP) in children is a clinically and genetically heterogeneous group of disorders. Disease-associated mutations have been identified in more than 50 genes. Recently, mutations in the mitochondrial tRNA processing gene, ELAC2, were reported to be associated with the recessively inherited form of hypertrophic CMP (HCM). This study is aimed at describing the cardiac phenotype and outcome of ELAC2 mutation. METHODS: We performed whole exome sequencing followed by targeted mutation screening to identify the genetic etiology of severe infantile-onset CMP in 64 consanguineous Saudi families...

OBJECTIVE: Transforming growth factor β1 (TGF-β1) is the major cytokine for stimulating endothelial cells (ECs) to transdifferentiate to mesenchymal cells (MCs) in the process known as endothelial-to-mesenchymal transition (EndMT). Recently, TGF-β1-induced EndMT has been implicated in the pathogenesis of atherosclerosis (AS). It has been identified that apolipoprotein A1 (ApoA-I) obstructs TGF-β1-induced endothelial dysfunction, providing a protective effect for ECs and also anti-AS activity...

We encountered a 45-year-old Japanese man who suffered from pulmonary thromboembolism and huge right ventricular thrombus after inferior vena cava (IVC) filter implantation without apparent thrombus in either the deep veins or inside the IVC filter. The biochemical data showed a discrepancy in the level of fibrinogen between the immunological and thrombin time methods, suggesting hypodysfibrinogenemia. The sequencing of the fibrinogen γ-chain gene (FGG) revealed a novel heterozygous missense mutation in exon 8 - a TGT to TCT transversion in codon 326 - resulting in an amino acid substitution of serine for cysteine (γCys326Ser)...

Stress echocardiography is a widely available, safe, low-cost, versatile imaging modality which is becoming increasingly recognized as a valuable tool in the assessment of patients with native and prosthetic left-sided valvular heart disease. It provides a quantitative assessment to help guide clinical decision-making when discordance exists between symptoms and severity of valve disease. Exercise (treadmill or bicycle) remains the preferred stress modality, but pharmacological augmentation with dobutamine can be used if needed...
