Filter by:Older patients with co-morbidity are increasingly represented in interventional cardiology practice. They have been historically excluded from studies regarding the optimal management of NSTEACS. Though there are associated risks with invasive treatment, such patients likely derive the greatest absolute benefit from PCI. Small, though highly selective, studies suggest a routine invasive strategy may reduce the risk of recurrent myocardial infarction. The study aims to include, as far as possible, an 'all-comers' population of patients aged 80 and above to define the optimum amount of revascularization required to achieve good outcomes and satisfactory symptom relief for this challenging cohort of patients.
68Ga-DOTATATE is a PET radiotracer with high affinity and selectivity for somatostatin receptor 2 (SSTR 2) and is approved clinically for the evaluation of patients with neuroendocrine tumors. The SSTR2 receptor is also highly expressed at the surface of human macrophages and lymphocytes. In comparison to FDG, 68Ga-DOTATATE presents the advantage of fast clearance from tissues, which are not expressing somatostatin receptors, in particular muscular and myocardial tissues, and the level of blood glucose does not influence its uptake. Accumulation of 68Ga-DOTATATE has already been detected in coronary and carotid plaques and is associated with the number of activated macrophages present in plaques obtained after carotid endarterectomy. In a recent study, Tarkin et al. confirmed the preferential uptake of 68Ga-DOTATATE by macrophages in atherosclerotic plaques. In addition, the intensity of 68Ga-DOTATATE was higher in culprit lesions in the carotid and coronary arteries than in stable lesions. The evaluation of 68Ga-DOTATATE uptake in coronary arteries was also strongly facilitated in comparison to FDG thanks to the absence of spillover signal from the myocardium. AAA has developed a new kit that has markedly simplified the synthesis of 68Ga-DOTATATE and has obtained in the US marketing authorization for the kit (Netspot; kit for the preparation of Gallium-68-DOTATATE injection for intravenous use) on June 1st 2016 (NDA 208547) for evaluation of patients with neuro-endocrine tumors. The Netspot kit will be used in this study for the detection of progressing coronary atherosclerosis.
The objective was to evaluate the efficacy and safety of combination of beraprost and aspirin for prevention of arteriosclerosis progress in type 2 diabetes mellitus patients.
Design: Single center, single-blind randomized controlled trial of patients with high risk native coronary artery lesions (defined as ≥2 contiguous yellow blocks on the block chemogram) requiring clinically indicated percutaneous coronary intervention. Patients will be randomized to either a combined intervention or conventional PCI. Cardiac biomarker measurements will be performed before PCI and 18-24 hours later. Treatment: Combined intervention consisting of pre-PCI intracoronary vasodilator and glycoprotein IIb/IIIa inhibitor administration, use of an EPD if technically feasible, and complete coverage of the lipid core plaque, if technically feasible. Control: Conventional PCI. Duration: 30 days follow-up. The primary trial objective is to compare the incidence and size of periprocedural MI, as assessed by the peak post-PCI troponin distribution in the two study groups. The secondary endpoints are: (1) Reduction in the incidence of >3x and >10x upper limit of normal increase in CK-MB. (2) Reduction in the incidence of slow flow/no-reflow post PCI. (3) Lower incidence of major adverse cardiac events, defined as the composite of death, acute coronary syndrome, or coronary revascularization) during 30-day follow-up.
The study tests if intense light could be a potential therapy in humans after myocardial infarction by inducing Per2.
The purpose of this study is to compare standard therapy (risk factor control, life style modification) versus standard therapy plus low-dose rosuvastatin therapy (5mg/day) on progression of coronary atherosclerosis in statin naive individuals who have mild CAD (nonobstructive coronary atherosclerotic plaques) and normal LDL (low-density lipoprotein) cholesterol levels(〈130mg/dl).
Presence of multiple traditional and nontraditional risk factors of atherosclerosis and cardiovascular disease (CVD) including inflammation in patients with chronic kidney disease (CKD) contribute to high CVD morbidity and mortality in this patient population. Additionally, the traditional approaches towards the therapy of CVD have little impact on CV mortality in these patients. Hydroxychloroquine (HCQ) used as anti-inflammatory in rheumatological disorders, has multiple beneficial properties relevant to the process of vascular disease. The effects of HCQ on atherosclerosis (AS) and vascular disease in CKD is not known yet. Thus, the study hypothesis is that HCQ treatment in individuals with CKD will provide clinically significant benefit in the management of CVD and will provide biological and functional atherosclerotic benefits.
The purpose of this study is to evaluate patency rates of the eSVS Mesh Saphenous Vein Graph (SVG) and control SVG at six and twenty-four months via coronary angiography and analyses of Duplex Sonography Results and coronary angiography and major cardiovascular or cerebrovascular event (MACCE)-Rate as well as analysis of preoperative great saphenous vein (GSV) duplex sonography and intra-operative GSV harvesting findings and procedure.
The purpose of this study is to evaluate patency rates of the external Saphenous Vein Support (eSVS) Mesh Saphenous Vein Grafts (SVG) and Control SVG at 3-6 months and 24 months.
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.
