View clinical trials related to Coronary Artery Disease.
Filter by:The present study is designed as a prospective, single centre, open label, observational trial. The study will collect information about the medical care patients receive during their planned procedure(s). No new testing or procedures will be done. Patients elected for hybrid revascularization will be asked their written consent to the use of their personal data. Left internal mammary artery to the Left Anterior Descending Coronary Artery (LIMA-LAD)surgical revascularization will be performed first, followed by percutaneous revascularization of the other vessels in the frame of the same hospitalization. After discharge patients will attend clinic visits at 30 days and 12 months, as per usual clinical practice, and will be contacted by phone at 6 months after procedure. Angiographic follow-up will be performed in symptomatic patients, as clinically indicated.
Intensive therapy with rosuvastatin 40 mg and ApoA-I Milano reduces the total atheroma volume (TAV) up to 6.38 or 14.1 mm3 respectively. Our previous bench studies PLASMONICS and NANOM First-in-Man trial documented TAV reduction up to unprecedented 79.4 and 60.3 mm3 respectively with high level of safety and feasibility. The completed randomized two arm (1:1) study (NANOM-PCI) with parallel assignment (n=62) assessed (NCT01436123) the safety and feasibility of the delivery technique for nanoparticles (NP) using micro-injection catheter (with intravascular intramural injection of allogeneous stem cells carrying NP after MSCT-, IVUS- and OCT-guided mapping of the vessel), and plasmonic photothermal therapy of atherosclerosis combined with stenting (Nano group, n=32) versus stenting with Xience V cage (Stenting group, n=30). The primary outcome was TAV at 12 months. The mean reduction of TAV at 12 months in Nano group was -84.1 mm3 (95% CI: SD 28.3; min -52.4 mm3, max -99.1 mm3; p<0.05) versus +12.4 mm3 in case of stenting (p<0.05 between groups). 42/62 patients (68%) in Nano group passed the Glagov threshold of a 40% plaque burden with mean plaque burden (PB) 36.2% (95% CI: SD 9.3%, min 30.9%, max 44.5%). The increase of the minimal lumen diameter was 61.2 and 63.3% at 12 month follow up in groups respectively. The serial assessment of VH-IVUS showed a significant decrease at 12 months in the dense calcium area, fibrous and fibro-fatty tissue with fulminant necrosis due to thermolysis in Nano-group, whereas an increase of fibrous and fibro-fatty components in stenting arm. We have documented 2 vs 3 cases of the definite thrombosis and 3 vs 5 cases of target lesion revascularization in groups respectively. The analysis of the event-free survival of the ongoing clinical follow-up shows the significantly lower risk of cardiovascular death in Nano group if compare with conventional stenting (93.4% vs 86.7%; p<0.05). Plasmonic resonance-mediated therapy using noble-metal NP associated with significant regression of coronary atherosclerosis. Tested delivery approach has acceptable safety and efficacy for atheroregression below a 40% PB. The investigators hypothesize that multistep approach with the use of stent in acute care unit, and then subsequent transcatheter micro-injection with nanoparticles can resolve atherosclerosis, stop and regress atherogenesis, remodulate or even rejuvenate arteries. Stem cells in patch can be good carriers for nanoparticles as well as high-effective metabolic vectors (paracrine-like regulation of alive cells and via bioactive products of cell lysis after detonation of nanoparticles) for the treatment of plaque on site. Gold nanoparticles with silica-iron oxide shells promise high-energy plasmonic photothermic burning or melting effect under the near-infrared laser irradiation onto the lesion. Thus the investigators expect complex two-side effect on the plaque with protected lumen and adventitia. Novel discoveries in atherogenesis, and development of nanobiotechnologies with potentials for the management of atherosclerosis leads us to the quest of new approaches. The investigators still cannot really effectively treat atherosclerosis. The investigators management is more symptomatic, and lipid-pool or inflammation-oriented! The investigators cannot manage non-organic part (mineral deposits, calcified necrotic core, partially collagen and fibrotic tissue) and total plaque volume Surgery and invasive procedures is just focused on blood flow restoration (just manipulate the form of plaque) + concerns of clinical and technical restrictions (incl. alien body - stent) + risk of restenosis or subacute 'fatal' in-stent atherothrombosis + graft survival/ occlusion + surgery-related complications High rate of short- and long-term complications and readmissions. Regression of atherosclerosis in fact is still a dream. The investigators offer an alternative to stenting and may be cardiac artery bypass surgery (CABG). Our approach can really allow to rejuvenate arteries, Plasmonic photothermal therapy (PPTT) can burn plaque, but stem cells and bioengineered structures promise restoration of the vessel wall. Our personal previous data showed that PPTT can 1.6-fold reduce a volume of plaque with most optimal long-term result in subsets with the use of SPCs as a delivery approach. The most optimal delivery systems of NPs into the plaque are the on-artery bioengineered patch and ferro-magnetic approach.
Individuals with kidney disease are at a higher risk for heart and vascular diseases, including heart attacks and strokes, than those with normal kidney function. The purpose of this research study is to collect information on the causes, complications and treatment of kidney disease. Patient characteristics, comorbid diseases and laboratory markers used in routine practice, as well as novel biochemical markers and genetic data will be collected to examine relationships between biochemical and genetic markers and cardiovascular risk. Information on the health history of incident hemodialysis and peritoneal dialysis patients will be captured using structured patient interviews and review of medical records. Blood and urine specimens will be collected at the time of dialysis initiation and stored in order to perform novel biochemical and genetic assays in the future. The overall goal of the CKDCS/LUCID study is improve understanding of cardiac-associated risks and to improve treatment in patients with kidney disease. A cardiac imaging substudy will be performed in a subset of patients enrolled. The goals of the substudy are to examine whether the risks of developing common cardiac-related complications (coronary artery calcification [CAC] and left ventricular hypertrophy [LVH]) are associated with certain medications taken by individuals on dialysis and whether these risks are modified by a genotypic predisposition.
This is a prospective, non-randomized, multicenter, pivotal Investigational Device Exemption (IDE) study. The intent of this study is to demonstrate the safety and effectiveness of the ST Monitoring Feature in St Jude Medical ICD systems.
The primary objective of this study is to compare the rate of device-oriented composite consisted of cardiac death, myocardial infarction not clearly attributable to a nontarget vessel, and clinically indicated target lesion revascularization among the patients treated with EES, ZES-R, or BES at 24-month clinical follow-up post-index procedure. Trial end points are summarized in Table I. The hypothesis is that BES is equivalent to EES or BES is equivalent to ZES-R at the primary end point.
Direct non-invasive coronary imaging by computed tomography (CT) has the potential to improve the workup of patients with stable chest pain complaints. The objective of the study is to compare in a randomized fashion the effectiveness and efficiency of a CT angiographic driven workup of suspected coronary artery disease in comparison to the standard workup using stress testing.
- Fimasartan will be more beneficial in stabilizing the plaque vulnerability compared to control group in deferred coronary lesions. - Fimasartan will be more beneficial in reducing total plaque volume compared to control group in deferred coronary lesions. - Fimasartan will be more beneficial in reducing functional impairment of stenotic lesions (assessed by FFR:Fractional Flow Reserve) in deferred coronary lesions.
The study is designed to evaluate the predictive accuracy of the CardioSond digital electronic stethoscope in the detection of coronary artery disease (CAD) in patients with and without known disease who are referred to cardiac computed tomography angiography (CT scans).
