Filter by:This is a multicenter survey of Russian data on target heart rate achievement in patients with stable angina and arterial hypertension who are currently treated with beta-blockers for at least 2 months and with no dose change for a minimum of 4 weeks
Pressure intermittent coronary sinus occlusion (PICSO) in patients with coronary artery disease improves collateral flow index to higher than 30%. PICSO used in this patient population is safe, feasible and effective. Safety, feasibility and effectiveness will be tested by periprocedural and logistic data.
The investigators hypothesize that the nanoburning is a very challenging technique to demolish and reverse the plaque especially in combination with stem cell technologies promising the functional restoration of the vessel wall. The completed (in July 2012) interventional three arms (n=180) first-in-man trial (the NANOM-FIM trial) assessed (NCT01270139) the safety and feasibility of two delivery techniques for nanoparticles (NP), and plasmonic photothermal therapy (PPTT) of atherosclerotic lesions. Patients were assigned in a 1:1:1 ratio to receive either (1) nano-intervention with delivery of silica-gold NP in mini-surgery implanted bioengineered on-artery patch (n=60), or (2) nano-intervention with delivery of silica-gold iron-bearing NP with targeted micro-bubbles or stem cells in hands of magnetic navigation system (n=60) versus (3) stent implantation (n=60). The primary outcome was TAV at 12 months. The observational prospective cohort analysis (an amendment to the protocol of August 29th 2012 with a decision to extend a 1-year study for another 4 years with the assessment of the 5-year clinical outcomes both retro- and prospectively) of the long-term clinical outcomes at the intention-to-treat population of 180 patients with CAD and angiographic SYNTAX score ≤22 enrolled initially to NANOM-FIM trial will be performed at 5 years after the intervention. The primary outcome will be a MACE-free survival. The secondary outcomes will be MACE, cardiac death, TLR (target lesion revascularization) and TVR (target vessel revascularization). Imaging endpoints will be assessed pre-, post- procedure and at 12-month follow-up. Clinical endpoints will be analyzed at the baseline and at 12 and 60-month follow-up (the release of results is expected after October 2016). Parameters of nanotoxicity will be assessed. The independent adjudication analysis of the clinical outcomes is scheduled in 2017-2019. The subset post-hoc analysis will be conducted at 1- and 5-year follow-up (by the Amendment of August 29th 2012). At the first subset, patients underwent stenting with XIENCE V stent proximal to the site of nano-intervention (n=13). Subjects in the second subset were undergone drug-coated balloon pre-dilation with further nano-technique (n=20). Lesions in patients of the third subset were not prepared for the nano-approach (n=147) (neither stenting nor balloon angioplasty). The analysis will be performed and results will be released after 2018 with the same clinical outcomes.

The purpose of this study is to determine if MR Perfusion Imaging is non-inferior to coronary angiography with measurement of Fractional Flow Reserve (FFR) in guiding management of patients with stable chest pain. - All patients will undergo an MR Perfusion Imaging test. - Further management will be guided by the result of the cardiac MRI in half of the patients (chosen by random). - The other half will undergo coronary angiography with measurement of FFR. The result of this test alone will guide their further management. The result of the initial MR Perfusion test will not be available to the treating doctors of this group. - All patients will receive optimal medical therapy (OMT) - All patients will undergo follow-up to find out if they have any relevant heart related events.
The purpose of this study is to test the hypothesis that application of topical capsaicin in patients with stable angina will result in improved exercise tolerance and reduced cardiac ischemia.
This is a multicentric randomized comparison between paclitaxel-coated balloon angioplasty or paclitaxel-eluting stent implantation in patients with stable or unstable angina with the evaluation of restenosis by Quantitative Coronary Analysis.
Treatments for stable angina includes drug therapy such as calcium-channel blocker, beta blocker, and ACEI/ARB. To obtain good prognosis in patients with coronary artery disease,preventing or correcting the progression of atherosclerosis and dyslipidemia is more important than relieving angina symptom. Dysfunction of microvessel is one of the most important factor in patients with coronary artery disease. Recently, we developed the new non-invasive method of evaluating the microvessel in fundus. With this methods, we will compare the effect of each drug (beta blocker, CCB, ARB).
The objective of this study is to evaluate if aggressive antiplatelet therapy would reduce ischemic events in aspirin (ASA) resistant patients after percutaneous coronary intervention (PCI).
Instead of treating in-stent restenosis, the best strategy for patients is preventing in-stent restenosis. Recent advances in the understanding of the cellular mechanism responsible for smooth muscle cell proliferation (neointimal hyperplasia), together with improvement in stent coating and eluting technology have provided the scientific background to develop drug eluting stents. Drug eluting stents (DES) are now the most promising development in interventional cardiology. Different classes of drugs mounted in a polymer layer on the surface of the stent have shown to be very effective in preventing neointimal hyperplasia. Currently there are 7 DES stents CE marked and commercially available on the market. Two stents, respectively the sirolimus eluting Cypher™ stent and the paclitaxel eluting Taxus™ stent, are in clinical use since 2002. The Cypher™ stent consists of the Bx sonic stent/balloon platform. The stent is coated with a non-degradable biocompatible PBMA/PEVA polymer which elutes sirolimius. The Taxus™ stent consists of the Express2 balloon/stent platform coated with non-degradable biocompatible Translute™ polymer which elutes paclitaxel. Recent large randomized trials like RAVEL, SIRIUS, E-SIRIUS C-SIRIUS (Cypher™ versus bare metal BX sonic™ stent), TAXUS II, IV, V, VI (Taxus versus bare metal Express™ stent) have shown that DES dramatically reduce the incidence of in-stent restenosis and subsequently the need for target lesion revascularization in patients with non complex and moderate long de-novo coronary lesions in vessels with a diameter between 2.5 -3.5 mm.1-11 Considering the very encouraging results of these early clinical trials with so far mid long term follow-up, there is the need to explore the utilization of DES in the other subsets of coronary lesions like: long lesions, chronic total occlusions, venous graft lesions, thrombotic lesions, restenosis lesions, ostial and bifurcation lesions and lesions in large vessels. As the result from the previous reported randomized trials, FDA and other regulatory institutes require that new DES are now being evaluated against one of the former DES (Cypher or Taxus). The XIENCE-V stent is a second generation DES, with thinner and more flexible Cobalt-Chromium stent struts, compared to the first generation Stainless Steel stent struts of Cypher and Taxus. This study addresses the questions whether the XIENCE-V™ stent has superior clinical results as the Taxus™ stent in the general population that is being referred for percutaneous coronary intervention (PCI). Objective of the study: The main objective of the study is a head tot head comparison of the everolimus coated XIENCE-V™ stent with the paclitaxel coated TAXUS™ stent in order to observe whether there is a difference in clinical outcome between both stents. Efficacy of both stents will be assessed by the composite end point of: all death, non fatal myocardial infarction and target vessel revascularization. Study design: Single center, randomised, open label study in all-comers referred for PCI. Study population: Approximately 1600 consecutive patients with coronary artery disease who are eligible according to the in- and exclusion criteria will be enrolled and randomized on a 1:1 basis. Primary study parameters/outcome of the study: The primary end point of the study is the composite end point of: all death, non fatal myocardial infarction, target vessel revascularization at 1 year. Secondary study parameters/outcome of the study: The secondary end points of the study are: A) The combined endpoint of cardiac death, non fatal myocardial infarction, ischemic driven target lesion revascularization (TLR) rate at 1, 6 and 12 months follow-up. B) The combined endpoint of all death, non fatal myocardial infarction, target vessel revascularization (TVR) rate at 2, 3, 4 and 5 years. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: The burden for the patient consists of filling in 8 questionnaires (1 A4 per questionnaire) in 5 years time. The first 3 questionnaires in the first year are also requested for monitoring purposes by the Ministry of Health and the Dutch Cardiology Society (Nederlandse Vereniging Voor Cardiologie; NVVC). There is no risk for the patient related to participation in this study. The patient will receive a Taxus or Xience-V stent anyhow, if the indication for a DES stent exists.
