Filter by:Prospective, multicenter, registry of at least 11,000 (and up to 15,000) consecutive patients with coronary artery disease undergoing stent-assisted percutaneous coronary intervention (PCI) using DES without major procedural complications.
XIENCE V® India is a prospective, open-label, multi-center, observational, single-arm study to evaluate XIENCE V® EECSS continued safety and effectiveness during commercial use in real world settings.
The purpose of this study is to prospectivly analyze the correlation of triglyceride tolerance and glucose tolerance with cardiovascular morbidity and mortality in patients with stable coronary artery disease within 18 months and to determine, whether measurement of triglyceride tolerance can discriminate patients at risk for cardiovascular events.
This study includes male subjects age 45 to 70, who have sustained a traumatic Spinal Cord Injury (SCI) at least 10 years prior. Subjects will be interviewed for demographic data, including heart disease risk factors. A blood test for cholesterol levels will be drawn. A CT scan of arteries of the heart will be performed to determine the presence of coronary calcium, a marker of subclinical Coronary Heart Disease. Scoring of Coronary Calcium or Coronary Calcium Score (CCS) is automated by the CT scanner. Each subject's Framingham Risk Score will be calculated; This is an individuals 10 year risk of having a Coronary Heart Disease event (significant symptoms). In addition, it will be determined if subjects are being treated for diagnosed dyslipidemia (high cholesterol) according to the National Cholesterol Educational Program (NCEP) guidelines. The proposed pilot study aims to better understand the problem of Coronary Heart Disease in individuals with Spinal Cord Injury, specifically CCS in SCI, when compared to the general population.
Since the advent of coronary stents, in-stent restenosis has proven to be the major limitation of interventional cardiology, occurring in as many as 30% of patients. Drug-eluting stents are specifically designed to prevent the problem of in-stent restenosis. They consist of a selective anti-proliferative drug, sirolimus, a controlled-release polymer, and a closed-cell stent delivery platform. Upon placement, sirolimus elutes into the vessel wall and stops the process of neointimal hyperplasia, thereby significantly reducing the incidence of in-stent restenosis. The study "Prevention of Coronary Restenosis" examines the effectiveness of sirolimus-eluting stents (SES) compared to bare-metal stents (BMS) in patients with coronary stenosis. The goal of the study is to examine whether the guideline-supported implantation of SES, despite the higher initial cost, improves the quality and economic outcomes of the treatment of patients with coronary stenosis. Secondarily, the study evaluates patient quality of life, impairment of daily activities, re-intervention rate, as well as an account of the utilisation and benefits of the implemented standardised guidelines. In this prospective, multi-centre, country-wide cohort study, 658 patients undergoing an implantation of a SES for treatment of coronary stenosis were recruited from 35 hospital centres. Their treatment and outcomes will be evaluated over a 3-year period by means of standardised questionnaires. In addition, information obtained from the patients will be confirmed and augmented by telephone interviews with the attending physicians involved in their follow-up care. In order to appraise the effect of the new therapy, a comparison cohort group of 394 patients receiving a BMS was recruited. These patients will be evaluated and observed by the same method as those patients receiving a drug-eluting stent, also over 3 years
Multislice CT angiography is a novel but already established and widely used in diagnosing coronary artery disease (CAD). It is very reliable in ruling out hemodynamically significant narrowings in coronary arteries (Negative predictive value). However, it may overestimate the severity of the stenoses in up to 30% of the coronary artery lesions (positive predictive value 70%). However, when coupled with a functional or flow-sensitive diagnostic test, such as PET perfusion or coronary doppler ultrasonography, one can assume that even the PPV may be as high as 95 %. Despite this assumption, there`s no scientific evidence to support use of such hybrid multi-modality tests at present. The investigators hypothesis is that improving the diagnostic accuracy of non-invasive diagnosis of coronary artery disease will decrease the proportion of patients that need catheter angiographies. The avoidance of these unnecessary invasive procedures will improve patients´ quality of life and may even redirect health care resources in a more efficient way.
The hypothesis is that western lifestyle, with sedentary behaviors and caloric excess promote a chronic, subacute inflammatory state that participates in the development and progression of atherosclerosis. We will evaluate the effects of targeting inflammation using the anti-inflammatory drug salsalate, compared to placebo, on coronary artery plaque volume assessed by multi-detector computed tomographic angiography (MDCTA). The TINSAL-CVD study is a randomized, double-masked, placebo-controlled, 2 arm, clinical trial. The purpose of the study is to compare the effect of salsalate or placebo on sub-acute inflammation and coronary plaque, in people with cardiovascular disease. Participants are randomized to active intervention (salsalate) or placebo interventions for a period of 30 months. The primary endpoint is change in plaque volume in the coronary arteries assessed by MDCTA from baseline to 30 months.
The aim of the present study was to evaluate the usefulness of an algorithm based on hemodynamic parameters obtained by single transpulmonary thermodilution (STD) combined with continuous monitoring of central venous oxygen saturation (ScvO2) for perioperative management of patients undergoing OPCAB.
The safety and efficacy of the Endeavor(TM) ABT-578 Eluting Coronary Stent System has been assessed in a series of studies. The stent is coated with a proprietary drug compound that is designed to reduce restenosis. This prospective multi-center study has been initiated: - To document the acute and mid-term safety and overall clinical performance of the stent system in a "real world" patient population requiring stent implantation. - To assess the event rate in patient subgroups with specific clinical indications and/or vessel or lesion characteristics.
Cardiopulmonary bypass (CPB) is known to alter pharmacokinetics (PK) and brain sensitivity to several drugs, including propofol. Few studies, however, have tested if propofol pharmacokinetical alterations observed after CPB could contribute to the increased hypnotic effect of propofol after CPB. This study was designed to test the hypothesis that changes in the PK of propofol contribute to an increase in its hypnotic effects after CPB as evidenced by changes in bispectral index (BIS) values. Twenty undergoing coronary artery bypass graft patients will be allocated in two groups: 1) CPB groups and 2) off-pump coronary artery bypass graft. Bispectral Index values and blood samples for plasma propofol concentration measurements will be collected along the surgery and up to 12 hours in the post-operative period. Plasma propofol concentrations, Bispectral index values and propofol PK will be compared between the groups.
