REVIEW
Motoaki Sano
Dipeptidyl peptidase-4 (DPP-4) inhibitors are oral antidiabetic drugs that safely reduce the blood glucose level over the long term. In Japan, DPP-4 inhibitors have become the oral antidiabetic drugs most frequently prescribed for patients with type 2 diabetes. However, the results of several cardiovascular outcomes studies have suggested that some DPP-4 inhibitors may increase the risk of hospitalization for heart failure. In patients with diabetes, heart failure is the most frequent cardiovascular condition, and it has a negative impact on the quality of life as well as being a potentially fatal complication...

REVIEW
Yuichi Saito, Yoshio Kobayashi
In patients with atrial fibrillation (AF), concomitant coronary artery disease is often present, and vice versa. Optimal antithrombotic treatment for patients with AF undergoing percutaneous coronary intervention (PCI) is one of the major concerns in the field of cardiology. Triple therapy, a combination of oral anticoagulant (OAC) plus dual antiplatelet therapy with aspirin and P2Y12 inhibitor, has been used for patients with AF undergoing PCI in recent decades to reduce ischemic events under guideline recommendations...

BACKGROUND: Transradial intervention (TRI) may cause damage to the radial artery (RA). We have demonstrated intima-media thickening and luminal narrowing of the distal RA after TRI using intravascular ultrasound (IVUS). This study aimed to determine the predictors of intima-media thickening of RA after TRI in the same patients using serial IVUS. METHODS AND RESULTS: We enrolled 110 consecutive patients who underwent TRI. IVUS of RA was immediately performed after TRI and repeated 6 months later...

BACKGROUND: High platelet reactivity before percutaneous coronary intervention (PCI) reportedly increases the risk of PCI-related myocardial infarction (PMI) following elective PCI. We conducted a pilot study to evaluate changes in platelet reactivity during PCI and their association with the incidence of PMI. METHODS: In total, 133 consecutive patients undergoing elective PCI after pretreatment with dual antiplatelet therapy for at least 7 days were prospectively enrolled...

BACKGROUND: The role of exercise echocardiography (ExE) for the assessment of patients with dyspnea is promising. We aimed to analyze the clinical characteristics and outcome of patients with this condition referred for ExE. METHODS: A total of 505 patients (66 ± 11 years, 57% women) referred for evaluation of dyspnea were considered. Mitral regurgitation, ratio of early left ventricular inflow wave to early diastolic annulus wave (E/e'), and wall motion abnormalities (WMAs) were measured at rest and at exercise...

BACKGROUND: The aim of this study was to determine whether major adverse cardiac events (MACE) during the late phase of the Fontan procedure could be predicted by strain measurements of single ventricles using cardiac magnetic resonance imaging with feature tracking (CMR-FT). METHODS: One hundred adolescent patients who underwent the Fontan procedure (mean age, 21 years) were examined retrospectively with CMR-FT to assess the systemic single-ventricle function. Vertical long-axis cine imaging was divided into six myocardial segments...

BACKGROUND: Sleep-disordered breathing (SDB) is a novel cardiovascular risk factor. To date, the effects of continuous positive airway pressure (CPAP) on coronary plaque atheroma in SDB patients with coronary artery disease (CAD) have remained unclear. The CPAP Effects on Atherosclerotic Plaques in Patients with Sleep-Disordered Breathing and Coronary Artery Disease (ENTERPRISE) trial was designed to evaluate the effects of CPAP treatment in addition to optimal medical treatment on coronary plaque regression in SDB patients...

REVIEW
Shigeru Miyagawa, Yoshiki Sawa
Although cell therapy using myoblasts, bone marrow cells, or other stem cells appears to improve functional recovery of the failing heart, mainly by cytokine paracrine effects, its effectiveness in severely damaged myocardium is limited, probably because there are too few residual myocytes to promote cytokine-induced angiogenesis. Recently, cardiogenic stem cells, such as c-kit-positive cells, were reported to generate cardiomyogenic lineages, and basic research experiments showed that implanting these cells, which can differentiate into cardiomyocytes, improves heart function...

BACKGROUND: Investigating regarding a predicted risk score of incident atrial fibrillation (AF) for an Asian general population has not been enough. Whether addition of electrocardiogram (ECG) variables to risk factors improves prediction of incident AF is unclear in a context that ECGs are extensively used at medical check-ups and outpatient clinics in Japan. METHODS: Participants undergoing periodic health check-ups during 2008-2014 followed-up by December 2015 including 96,841 (65...

BACKGROUND: High on-treatment platelet reactivity (HPR) under clopidogrel treatment is frequently observed in hemodialysis (HD) patients. In such patients, 10mg of prasugrel has reportedly inhibited platelet reactivity more adequately compared with 75mg of clopidogrel. However, the efficacy of 3.75mg prasugrel in Japanese HD patients is largely unknown. METHODS: A total of 41 Japanese coronary artery disease patients under HD who received aspirin and clopidogrel were enrolled...

BACKGROUND: Although cardiac sarcoidosis is associated with poor prognosis, diagnosis of the disease is challenging and the sensitivity and specificity of diagnostic modalities are limited. This study was performed to evaluate the potential of serum microRNAs (miRNAs) as diagnostic biomarkers for cardiac sarcoidosis. METHODS: We performed genome-wide expression profiling for 2565 miRNAs (Human-miRNA ver.21) using peripheral blood samples from 5 patients with cardiac sarcoidosis (61±9 years) and 3 healthy controls (54±7 years)...

OBJECTIVE: Despite use of provocation testing to unmask dormant left atrium (LA)-PV conduction after index pulmonary vein isolation (PVI) for atrial fibrillation (AF), AF recurrence still occurs, with PV reconnection as the main cause. In an effort to answer the question whether freedom from AF recurrence can be achieved by ablation that targets sites of dormant conduction, we compared sites of dormant conduction against sites of PV reconnection identified at the time of repeat ablation for AF recurrence...

BACKGROUND: The novel J-Valve (JC Medical Inc, Burlingame, CA, USA) was developed to cope with aortic valvular disease by facilitating accurate positioning. We present the first one-year results regarding the safety and efficacy of the J-Valve system implantation in patients with severe aortic stenosis (AS) or aortic regurgitation (AR) undergoing transapical-transcatheter aortic valve implantation. METHODS: This prospective multicenter study enrolled 107 high-risk patients (mean age 74...

BACKGROUND: Management of adult congenital heart disease (ACHD) patients requires understanding of its complex morphology and functional features. An innovative imaging technique has been developed to display a virtual multi-planar reconstruction obtained from contrast-enhanced multidetector-computed tomography (MDCT) corresponding to the same cross-sectional image from transthoracic echocardiography (TTE). The aim of this study is to assess the usefulness of this imaging technology in ACHD patients...
