Filter by:The purpose of this study is to test the expression of microRNAs related to the syndromes after the intervention of Tongguan capsule,preliminarily to investigate the mechanism of the effects of Tongguan capsule, and provide the biological foundation of curative effect of Tongguan capsule.
The objectives of this study are 1. To establish a prospective registry of the whole patients who received percutaneous coronary intervention with Xience Xpedition™/Alpine™ stent 2. To evaulate the long-term efficacy and safety of coronary stenting with the Xience Xpedition™/Alpine™ stent 3. To compare the long-term efficacy and safety of coronary stenting between the Xience Xpedition™/Alpine ™ stent and other contemporary drug-eluting stents which had established their own registry
To evaluate safety of reduction of dual antiplatelet therapy period to three months after implantation of Ultimaster sirolimus-eluting stent (U-SES). Additionally to investigate appropriateness of thienopyridine monotherapy with discontinuation of aspirin.
This study evaluates the effects of emotional status on coronary flow in patients undergoing elective coronary angiography. Patients whom undergoing elective coronary angiography will fulfill the Beck Anxiety Inventory, Beck Depression Inventory, State-Trait Anxiety Inventory, Hospital Anxiety and Depression Scale. State Anxiety Inventory will be fulfilled both before the intervention and after 1 hour the patients learned the results of the coronary angiography. The other scales will be performed after 1 hour the patients learned their results. Coronary flow will be assessed by TIMI (Thrombolysis In Myocardial Infarction) frame count method.
The aim of this study is to evaluate and describe the total coronary circulation time (TCCT) by using TIMI frame count method in patients performed coronary angiography. TCCT is described as an angiographic index which is the sum of the frame count of coronary artery and venous system. This study also evaluates the relationship between the diseases in arterial system such as coronary artery ectasia, coronary slow flow, coronary artery disease and coronary venous pathologies.
Prospective, non-randomized, multi-center study assessing the long term safety and efficacy of the self expandable sirolimus eluting Xposition S stent in the treatment of unprotected left main coronary artery disease.
PCI of diffuse long coronary lesions still remains challenging because of relatively high risk of in-stent restenosis and stent thrombosis compared to short coronary lesions. The purpose of the study is to compare an incidence of composite of major adverse cardiovascular events (MACEs) at 1 year between Absorb everolimus-eluting BVS and Xience EES after coronary intervention in long lesions.
The investigators propose to develop a computational framework involving a novel automatic image segmentation algorithm based on CTA images, an artery model reconstruction algorithm for stenosis detection, and quantification of severity of stenosis in terms of area stenosis.
Self-apposing, drug-eluting Stentys coronary stents represent a valuable tool for the treatment of coronary artery stenosis. Their ability to adapt to widely varying vessel calibers and to auto-expand after their release to self-appose to vessel walls is particularly useful in the presence of ectasic coronary arteries or significant vessel tapering. The investigators planned this study to assess the feasibility, the effectiveness and the safety of the implantation of self-apposing, drug-eluting Stentys stents for percutaneous coronary intervention. Consecutive patients undergoing percutaneous coronary intervention with implantation of a self-apposing Stentys stent were enrolled in this multi center registry. Inclusion criteria were age ≥ 18 years and ability to provide informed consent. No exclusion criteria were defined. Primary end-point of the study is the occurrence of MACE (death, myocardial infarction, stent thrombosis, unplanned hospitalization for unstable angina, target lesion revascularization). Secondary end-points include individual components of MACE, procedural complications (periprocedural MI, bleedings, access site complication, failure to cross stent struts with guidewire in the treatment of bifurcation, failure to delivery the stent, contrast-induced nephropathy), bleedings at follow up.
As the end stage of almost all cardiovascular diseases, heart failure has become an increasingly common cause of cardiovascular morbidity and mortality worldwide. In China, coronary artery disease (CAD) has become the main cause of heart failure in recent years. CAD combining with heart failure usually predicts poor outcome, with coronary revascularization the most universally used therapy. However, the difference of several types of such therapy has less well been compared. Thus, the study mainly aims to compare different types of coronary revascularization therapies such as Percutaneous Coronary Intervention (PCI),Coronary Artery Bypass Grafting (CABG) as well as Hybrid Coronary Revascularization (HCR), and also make the optimization strategy especially in patients with heart failure. The study also aims to investigate whether disease progression in patients with chronic heart failure (CHF) can be assessed by new biomarkers and determine their diagnostic and prognostic value, relating several cardiac functional parameters to clinical outcome.
