Filter by:Survivors of Hodgkin Lymphoma (HL) are known to have an increased risk of developing late treatment sequelae such as cardiovascular events due to coronary artery disease. At present no active screening is performed in these patients since it is not known whether screening and subsequent treatment by means of revascularization is effective in reducing the risk of cardiovascular events in symptomatic individuals. In the trial the efficacy and therapeutic consequences of screening for coronary artery diasease by multi-slice CT (MSCT) among asymptomatic HL survivors will be evaluated.
Impact of intraventricular electrical activation in resynchronization therapy. We seek to evaluate the impact of Cardiac Resynchronization Therapy (CRT) on electrical activation of the Left Ventricle (LV). The first goal of the study is to evaluate if CRT is able to decrease the heterogeneity of LV activation in heart failure patients. A second goal is to evaluate the electrical determinant of clinical response to CRT using invasive and non-invasive mapping technology.
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. This project and related manuscripts were not prepared or funded in any part by a commercial organization. Nanoparticles and biomedical equipment were supplied free for the study by the non-profit Agiko and De Haar Research Task Force (Rotterdam-Amsterdam, the Netherlands).

The access of the international academic or governmental organizations to the essential and primary data of the trial is restricted by the Russian governmental authorities due to the interest of the Russian Federal Security Service (FSB).
Antiplatelet therapy is critical in the management of coronary artery disease.For patients undergoing off-pump coronary artery bypass graft,controversy remains regarding the safety of preoperative antiplatelet therapy.And there is little study about the effect of continuing aspirin until the surgery day on graft patency.So we would like to perform this study to evaluate the effects of preoperative aspirin on graft patency and cardiac events in off-pump coronary bypass.
To compare the safety and efficacy of coronary stenting with everolimus-eluting stent (Promus Element®) and biolimus-eluting stent with biodegradable polymer (Nobori®)
The CANARY (Coronary Assessment by Near-infrared of Atherosclerotic Rupture-prone Yellow) Study is a pivotal trial to evaluate criteria for defining a Lipid Core Plaque (LCP) that is at high risk of rupturing during standard of care therapy and causing intra-procedural complications. If plaques that require treatment are at higher than normal risk of causing intra-procedural complications, some life threatening, the treating physician is better informed and may opt to take precautionary measures to mitigate the risk or result of a complication. The CANARY Study is also designed to evaluate the feasibility of using a distal embolization protection device (EPD) as a means to prevent heart attacks triggered by the embolization of plaque during standard care therapy. It is thought that the EPD will prevent plaque from going downstream during treatment and obstructing other heart vessels. These obstructions could cause heart attacks by preventing blood from reaching heart muscle tissue.
The investigators will evaluate 100 regular red wine consumer men and 100 abstainers men from 50 years-old to 70 years-old by coronary risk prevalence, mood status, anthropometric measures, daily caloric ingest, lipid profile, carotid intimal media thickness, brachial flow mediate dilatation, coronary tomographic angiography and leucocyte telomere length. The sample size has been calculated expecting that regular red wine ingestion would lead to a five year old younger vascular ageing indexes measured by carotid intimal media thickness, coronary artery calcium scores and leucocyte telomere length longer than those abstainers subjects at same age. The investigators hypothesized that regular wine consumers present less coronary lesion and coronary calcium score on coronary tomographic angiography, lower carotid intimal media thickness and higher mean telomere length due the benefice of wine.
BBK- 2 - study: STUDY-SUMMARY Background: The need for stenting of the main and side branch (double stenting) in the treatment of coronary bifurcation lesion primarily depends on the complexity of the bifurcation lesion. If the bifurcation lesion is very complex (Medina classification 111, severe stenosis of both branches, severe calcified lesion, long lesions etc.) double stenting may be the treatment of choice. When double stenting is required, the most frequently used stenting techniques are T-stenting and Culotte-stenting. It is still unclear, however, which double stent technique yields the best long-term outcome. Aim: This randomized study will compare the long-term safety and efficacy of T-stenting versus Culotte-stenting in the treatment of de-novo coronary bifurcation lesions with drug-eluting stents. Methods: Three-hundred patients in whom a double-stenting technique is intended for the treatment of a de-novo coronary bifurcation lesion will be randomly assigned to T-stenting or Culotte-stenting with an approved drug-eluting stent. Patients will undergo 9-month angiographic follow-up with quantitative coronary angiography. Clinical follow-up is planed at 30 days, 6 months, 1 year, 2 years, 3 years and 5 years. The primary study endpoint is the maximal percent diameter stenosis in the bifurcation lesion at 9 months. Secondary endpoints include binary restenosis (estimated by Quantitative Coronary Angiography (QCA) analysis), Target Lesion Revascularisation (TLR), Freedom from Major Adverse Cardiac Events (MACE) and the rate of stent thrombosis according to the definition of the Academic Research Consortium (ARC definition). The study will have 90% power to detect a 25% reduction in the primary endpoint at p < 0.05.
