Objectives The purpose of this randomized trial was to compare the incidence slow flow between low‐speed and high‐speed rotational atherectomy (RA) calcified coronary lesions. Background Preclinical studies suggest that is less frequently observed with than RA because platelet aggregation RA. Methods This a prospective, randomized, single center study. A total 100 patients lesions were enrolled randomly assigned in 1:1 ratio (140,000 rpm) or (190,000 primary endpoint occurrence following...
Peripheral venoarterial extracorporeal membranous oxygenation (ECMO) support is effective in patients with cardiogenic shock or fatal arrhythmia due to fulminant myocarditis. The clinical courses of myocarditis are still uncertain; therefore, it difficult determine the appropriate time for discontinuing ECMO converting a ventricular assist device. purpose this study was investigate prognosis managed by ECMO. Twenty-two consecutive peripheral between 1999 and 2013 were enrolled. Survival...
Data from randomized trials investigating different access closure strategies after transfemoral transcatheter aortic valve implantation (TF-TAVI) remain scarce. In this study, two vascular device (VCD) to achieve hemostasis TF-TAVI were compared.
Objective Immediate primary percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction is closely associated with better clinical outcomes. However, the optimal timing of PCI culprit lesion in non-ST-elevation (NSTEMI) not fully understood. The aim this study was to compare outcomes between patients early and delayed investigate whether within 24 hours admission can improve long-term NSTEMI. Methods This a single-center, retrospective study. endpoint major...
The below the knee (BTK) arteries of legs with peripheral artery disease (PAD) frequently exhibit medial calcification and chronic thrombus. However, relationship between thrombus remains poorly understood. This study aimed to evaluate association in BTK patients PAD using optical frequency domain imaging (OFDI). OFDI frames were analyzed undergoing OFDI-guided endovascular therapy. Data regarding thrombus, calcification, type extent collected. multivariate logistic regression analysis was...
Compared to acute myocardial infarction (AMI) with single vessel disease (SVD) or double (DVD), AMI triple (TVD) is associated higher mortality. The aim of this study was identify the determinants in-hospital death in TVD. We identified patients TVD our tertiary medical center between January 2009 and December 2014. Baseline patient characteristics including laboratory data, echocardiograms, coronary angiograms were collected from hospital records. divided population into a survivor group...
Objectives This study aimed to compare the mid-term clinical outcomes of intravascular ultrasound (IVUS)-calcified nodules between percutaneous coronary intervention (PCI) with and without rotational atherectomy (RA). Background There has been a debate whether use RA for revascularization calcified nodule. Although can ablate structure within nodule may facilitate adequate stent expansion, provoke severe perforation, because typically shows eccentric calcification. Methods We included 204...
Calcified nodule (CN) has been known as the advanced stage of coronary calcification. However, clinical outcomes following percutaneous intervention (PCI) to CN remain unknown. This study aimed compare outcomes, including target lesion revascularization (TLR), between calcified lesions with and without CN.Two hundred forty-nine undergoing intravascular ultrasound-guided PCI rotational atherectomy (RA) were enrolled divided into group (n=100) non-CN (n=149) according presence CN. The...
Intravascular ultrasound (IVUS) can provide useful information in patients undergoing complex percutaneous coronary intervention with rotational atherectomy (RA). The association between IVUS findings and slow flow following (RA) has not been investigated, although shown to be an unfavorable sign worse outcomes. aim of this study was determine the IVUS-factors associated just after RA. We retrospectively enrolled 290 lesions (5316 IVUS-frames) RA, which were divided into group (n = 43 1029...
Dipeptidyl peptidase-4 (DPP-4) inhibitors increase endothelial progenitor cells (EPCs) in peripheral blood circulation. However, the underlying mechanisms and effects on vascular function remain unclear. We evaluated whether DPP-4 inhibitor teneligliptin increases circulating EPCs by inhibiting stromal-derived factor-1α (SDF-1α) improves flow-mediated dilatation (FMD) type 2 diabetes mellitus patients with acute coronary syndrome (ACS) or its risk factors.This single-center, open-label,...
Right ventricular infarction (RVI) is a complication following inferior ST-elevation myocardial (STEMI). The aim of the present study was to investigate clinical outcomes RVI in contemporary primary percutaneous coronary intervention (PCI) era. endpoint in-hospital death, and secondary major adverse cardiac events (MACE), defined as composite cardiovascular re-hospitalization for heart failure, non-fatal acute (AMI). Event-free survival curves MACE were constructed using Kaplan-Meier method,...
Acute ischemic stroke (AIS) is a rare but critical complication following ST-elevation myocardial infarction (STEMI). The risk of AIS or transient attack (TIA) may be amplified by invasive procedures, including primary percutaneous coronary intervention (PCI). This study aimed to investigate the factors associated with in-hospital AIS/TIA in patients STEMI who required PCI. We included 941 underwent PCI and divided them into an group (n = 39) non-AIS/TIA 902), according new-onset AIS/TIA....
Recently, long-term outcomes of pre-capillary pulmonary hypertension (PH) have been improved, whereas morbidity and mortality are still high because right-sided heart failure (HF). Right-sided HF is closely related to right ventricular (RV) function hemodynamics such as RV stroke work index (RVSWI). However, the association between RVSWI in PH has not well investigated. The aims this study were compare clinical characteristics low investigate patients with PH. We included admitted diagnose...
Peripheral arterial disease (PAD) is the well-known risk factor for cardiovascular events. Although low ankle-brachial index (ABI) recognized as a in general population, ABI without any symptoms of PAD has not been established prognostic marker patients with acute myocardial infarction (AMI) yet. The purpose this retrospective study was to examine whether asymptomatic associated long-term clinical outcomes AMI treatment history PAD.
