Active clinical trials for "Coronary Disease"

A higher degree of platelet inhibition remains the goal of peri-interventional and long-term anti-thrombotic therapy in patients with coronary artery disease. In clinical practice, patients undergoing percutaneous coronary intervention with stent implantation who are already on clopidogrel therapy get re-loaded with clopidogrel. This is based on prior observations showing that higher inhibition of platelet aggregation may be achieved by giving a loading dose of clopidogrel in patients with coronary artery disease while on chronic clopidogrel therapy. However, to date it is unknown if greater inhibition of platelet aggregation can be achieved by adding a prasugrel loading dose in patients on chronic prasugrel therapy. Therefore, understanding the pharmacodynamic implications of a prasugrel re-load strategy in patients on already on chronic prasugrel therapy will be useful.

The overall purpose of the FAME II trial is to compare the clinical outcomes, safety and cost-effectiveness of FFR-guided PCI plus optimal medical treatment (OMT) versus OMT alone in patients with stable coronary artery disease.

This is a single-center study of subjects undergoing clinically indicated heart scans for evaluation of known or suspected heart disease. We will also include 10 healthy subjects without known heart disease. We would like to study stress testing of the heart using exercise and a medication called regadenoson. Imaging of the heart will be performed.

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.

This study evaluated and optimized settings for, and evaluated the performance of, AI-700-enhanced echocardiographic imaging on several ultrasound imaging platforms, as well as collected additional safety data for AI-700 in healthy volunteers and stable cardiac patients.

Increases in carotid artery intima-media thickness (IMT) are correlated with increased risk of stroke and myocardial infarction. The purpose of this study is to assess if pomegranate juice will retard the carotid (IMT) progression rate in men and women who have one or more existing cardiovascular risk factors (current cigarette smoking, hypertension, low HDL-cholesterol, and/or high LDL-cholesterol) upon entrance into the study.

This study is intended to assess the safety and tolerance of regadenoson in subjects with renal impairment.

The purpose of this study is to determine the possible preventive effect of behavioural modification versus standard treatment after hospital discharge in CHD patients.

Safety and dosimetry of CardioPET™ will be evaluated in normal healthy volunteers and CAD subjects both male and female between the ages of 50-85. Nine normal controls will undergo repeated whole body imaging for biodistribution and dosimetry estimation. Six other normal healthy subjects will undergo heart imaging only. Six CAD subjects will undergo heart imaging only.

Air pollution is a major cause of cardiovascular morbidity and mortality. The components of air pollution responsible and the mechanisms through which they might mediate these harmful effects remain only partially understood. We hypothesise that these adverse effects are mediated by combustion derived air pollutants and that even a brief exposure will effect heart and blood vessel function. We assess the effect of dilute diesel exhaust inhalation at levels encountered in urban road traffic on heart and blood vessel function in patients with stable coronary heart disease.
