Active clinical trials for "Coronary Artery Disease"

Prospective, multi-center, randomized, within-subject-controlled , trial, enrolling patients with multi vessel atherosclerotic coronary artery disease, scheduled to undergo SVG CABG with arterial grafting of IMA to LAD and two or more saphenous vein grafts. In each patient, one SVG bypass will be randomized to be supported by the VEST, while another will not be supported and serve as control. Thus, the full cohort will provide a basis for comparison between two sets of SVGs: A VEST supported set; and an unsupported set.

Randomized studies may often be burdened by the selective nature of patient inclusion thus not reflecting real-world outcomes. This is evident from the discrepancy in the mortality rates reported in major randomized trials enrolling patients with acute myocardial infarction (AMI), as compared with registry data. The primary objective of this observational study is to assess short- and long-term outcomes of unselected, real-world patients presenting with AMI and treated with contemporary percutaneous coronary intervention (PCI).

The investigators aim to investigate the prognostic implication of stenosis and plaque features on coronary CT angiography (CCTA), physiologic assessment, and pharmacotherapy after invasive coronary angiography.

At present, the investigators don't know the relationship between plaque stability and the metabonomics changes. In the present study, investigators will evaluate the plaque stability by intravascular unltrasound in stable coronary heart patients, and metabonomics was also assessed by high throughput sequencing. Statistic analysis were carried out to analyze the correlation between plaque stability and metabonomics changes among these study patients.

this is an observertional study aimed at Study the association between Insulin resistance estimated by HOMA and Angiographic Severity of Coronary Artery Disease in Non Diabetic & Non Obese Patients.

Coronary bifurcation lesions are lesions (or blockages) that occur at or near the intersection of a major coronary artery and one of the arteries' side branches. Numerous techniques and devices have been developed to treat coronary bifurcations; however, these types of lesions remain some of the most challenging, both in terms of procedural success and outcome. This study is designed as an observational, multi-center registry that will collect information on treatment strategies and outcomes of consecutive patients undergoing percutaneous coronary interventions (PCI) in coronary bifurcations among various participating centers, in order to determine the frequency of bifurcation PCI, the procedural strategies utilized, and the procedural outcomes.

Prospective, single-center, clinical registry of patients with symptomatic/critical carotid artery stenosis at risk of stroke coexisting with unstable or multivessel severe coronary artery disease and/or severe valvular heart disease undergoing endovascular treatment of carotid atherosclerosis using a mesh stent in combination with cardiac surgery (coronary artery bypass grafting (CABG) and/or valve surgery). A study involving clinical data evaluation of truly simultaneous treatment outcomes in patients deemed to require carotid revascularization at the time of surgical cardiac intervention (single-stage, simultaneous treatment). An open-label study, without randomization - a single arm study. Academic Registry - scientific activity of the Faculty of Medicine, Collegium Medicum, Jagiellonian University and John Paul II Hospital.

This is a prospective registry to enroll complex high-risk coronary heart disease patients. The purpose of this study is to compare intracoronary physiology and imaging-guided intervention strategy and angiography-guided intervention strategy for clinical outcomes and health economics.

To evaluate the biomarkers for the prognosis of coronary heart disease, patients with coronary heart disease will be recruited and followed up for at least 2 years.

Heart attacks caused by the complete blockage of a heart artery are treated by opening it with a stent. However, most people will also have 'non-culprit' narrowings found in their other arteries at this time. Although in general people do better if these non-culprit narrowings are also treated with stents if they look severe, this process has problems. This is because narrowings that look severe may be stable and not cause any trouble. For these people a stent is a wasted procedure and unnecessary risk. On the other hand, narrowings that are currently left alone because they appear mild, may progress and cause a heart attack. Participants who have had a heart attack will have a scan from inside the heart arteries during an angiogram (optical coherence tomography, OCT) and a magnetic resonance angiogram (MRA). If the investigators can show that it is possible to accurately predict which non-culprit narrowings are going to progress and which are going to stabilise, medical professionals may be able to better target their treatments after a heart attack.
