Cardiovascular diseases (CVD) are a global leading cause of mortality. However, few biomarkers are available to predict future coronary plaque rupture. We have recently demonstrated that low levels of anti-apolipoprotein B-100 autoantibody (anti-apo B-100 Ab) correlated with an increased CVD risk in Japanese patients with diabetes. In the present study, we examined the relationship between serum anti-apo B-100 Ab levels and coronary plaque characteristics in patients undergoing elective percutaneous coronary intervention (PCI). We conducted iMAP -intravascular ultrasound (IVUS) in 88 Japanese male patients undergoing elective PCI, and the five consecutive slices of IVUS images at the center of the most stenotic culprit lesion were used for identifying the plaque characteristics. The serum levels of anti-apo B-100 Ab against synthetic peptides (p45 or p210) were measured using a homemade enzyme-linked immunosorbent assay. Serum IgG levels of anti-apo B-100 Ab against both native p45 and p210 (IgG and IgG ) and malondialdehyde (MDA)-modified p45 and p210 (IgG or IgG ) showed a negative correlation with plaque burden in total male patients undergoing elective PCI. Additionally, both IgG and IgG , but neither IgG nor IgG , correlated negatively with necrotic and positively with fibrotic components of iMAP -IVUS plaque characteristics in the patients with ＜1 month statin treatment before elective PCI ("statin-untreated" group). There was no significant correlation between anti-apo B-100 Ab and any plaque characteristics in the patients with statin treatment for 1 month or more before elective PCI ("statin-treated" group). Measuring serum levels of anti-apo B-100 Ab might be helpful in the evaluation of unstable coronary plaque in male CVD patients without statin treatment.Measuring serum levels of anti-apo B-100 Ab might be helpful in the evaluation of unstable coronary plaque in male CVD patients without statin treatment. Arterial narrowing associated with the progression of atherosclerosis leads to serious conditions such as stroke, coronary artery disease, or even death. see more High-resolution magnetic resonance imaging (HR-MRI) is better for detecting arterial wall status and discriminating tissue characteristics than conventional imaging. We used HR-MRI to investigate the frequency of patients with basilar artery (BA) stenosis observed distinctively on routine angiography and identify the clinical features associated with this imaging. We analyzed the nature of the vessel wall causing the basal artery stenosis by HR-MRI, and related clinical factors. Patients with BA stenosis underwent HR-MRI. The association between atherosclerosis (with or without intraplaque hemorrhage [IPH]) and dissection was analyzed. High signal intensity within a BA plaque on magnetization-prepared rapid acquisition with gradient echo was defined as an area with a signal intensity ＞200% that of the adjacent muscle. Fifteen patients were diagnosed wiposterior circulation stroke are required.Heart failure (HF) is a major cause of death and hospitalization worldwide. In particular, hospital readmission due to worsened HF occurs frequently after the onset of HF. However, the association of repeated hospital admission with clinical manifestations and outcomes is unclear. The aim of this study was to clarify the serial changes in presentation and clinical course of patients requiring repeated hospital admission due to worsened HF. Among 466,921 patients who were admitted and discharged between January 2010 and March 2018, with the main discharge diagnosis of HF, we studied 5,740 patients who were hospitalized 4 times or more, using the Diagnosis Procedure Combination database. We evaluated serial changes in continuous data using the Jonckheere trend test, and categorical data using the Cochran-Armitage trend test. The median age of the patients was 78 years, and 3,326 patients (58%) were male. Body mass index and Barthel Index decreased with increased numbers of admissions. Patients requiring respiratory support and hemodialysis increased, whereas patients undergoing intra-aortic balloon pumping decreased with increased numbers of admissions. The length of hospital stay was prolonged and the interval between hospitalizations was shortened with increased numbers of hospital admissions. The in-hospital mortality rate was 8.8% at the fourth admission. In conclusion, this is the first large-scale real-world study on the serial changes in characteristics and outcomes of HF patients requiring repeated hospitalization, suggesting that repeated hospitalization might adversely affect the general status of patients with HF and result in a vicious clinical cycle.Atrial fibrillation (AF), one of the common clinical arrhythmias, lacks effective treatment manners. Cardiac fibroblasts play an essential role in myocardial fibrosis and cardiac remodeling, which are involved in AF progression. Reportedly, MicroRNAs (miRNAs) regulate the myocardial fibrosis in AF. However, whether miR-324-3p involves myocardial fibrosis in AF and the tentative molecular mechanisms of miR-324-3p regulating cardiac fibroblasts during AF remains unknown. In the present study, miR-324-3p was found to be decreased in patients with AF and AF rat model. Next, we investigated the effect of miR-324-3p on myocardial fibroblast proliferation through miR-324-3p overexpression and found that miR-324-3p inhibited fibroblast proliferation in vitro. Furthermore, we found that miR-324-3p directly targeted transforming growth factor β1 in fibroblast, which may be involved in the development of myocardial fibrosis during AF. Meanwhile, miR-324-3p mimics treatment suppressed the PI3K/AKT signaling pathway in fibroblast. These results demonstrated a molecular mechanism of miR-324-3p regulating fibroblast proliferation in vitro, which might provide a novel potential treatment manner in AF in clinic.Our study aimed to investigate whether the frame design of transcatheter heart valve (THV) affects the procedural and clinical results of transcatheter aortic valve implantation (TAVI).We retrospectively reviewed 163 patients with aortic stenosis who underwent TAVI using different types of THV (Edwards SAPIEN, n = 31; Venus-A, n = 63; and J-Valve, n = 69). The procedural outcomes and follow-up results for 1-year were compared among groups.The patients who underwent TAVI using J-Valve had a higher mean transaortic pressure gradient than those using SAPIEN or Venus-A after TAVI (1-year follow-up; P = 0.017, P less then 0.001, respectively), whereas no difference was observed between the patients with SAPIEN and Venus-A prosthesis (P = 0.150). The incidence of permanent pacemaker implantation was highest in patients with Venus-A (19.0%), followed by SAPIEN (9.7%), and lowest in J-Valve (4.3%) (P = 0.025). No difference was observed in the 30-day mortality rate among the groups (P = 1.000). Moreover, Kaplan-Meier survival analysis revealed that there was no significant difference in the 1-year cumulative patient survival rate among three patient cohorts (log-rank, P = 0.
