Active clinical trials for "Coronary Artery Disease"

Prospective, multi-center, randomized, controlled pilot study to demonstrate the safety and effectiveness of the VGS Fluent external support device, supporting saphenous vein grafts in patients with coronary heart disease.

The main purpose of this study is to determine whether intravenous glutamate infusion given in association with surgery for unstable coronary artery disease can protect the heart from myocardial injury, postoperative heart failure and death.

The purpose of this study is to determine whether it is safe to receive an injection of your own bone marrow adult stem cells (autologous BM-MNC) to your heart wall during coronary artery bypass graft (CABG).

Background: Treatment targets for cardiac risk factor reduction are not being met. Therefore, there is a need for new strategies to assist patients in meeting these goals. Objective: To determine the amount of any additional benefit on risk factor reduction associated with the consumption of the "dietary portfolio" (a low fat diet with soy, nuts and viscous fibres), above that achieved with medical management in diabetic patients following cardiac surgery. Description: 35 cardiac surgery patients with diabetes will be instructed on how to incorporate the dietary portfolio foods into their diet for four weeks. Changes in blood cholesterol, markers of inflammation, blood sugar control and modifiable risk factors will be assessed after 2 and 4 weeks of therapy. Relevance: Maximizing cardiac risk factor reduction through a combined approach (dietary plus medication) should improve outcomes, reduce rates of re-hospitalization and improve quality of life in diabetic patients after heart surgery.

This study is to determine the effect of adalimumab on inflammation of blood vessels that could lead to heart attack in patients with psoriasis. Changes to the carotid artery and ascending aorta will be evaluated in patients treated with adalimumab (systemic treatment) and compared against patients treated with a topical treatment that does not affect the entire body.

Binodenoson (an experimental drug) and adenosine (an FDA-approved drug that is currently used by doctors) are used to increase blood flow to the heart just like when a person exercises on a treadmill. Using imaging techniques, this increased blood flow can help determine if areas of the heart are not getting enough blood and oxygen during exercise. The purpose of the study is to determine if binodenoson is as good as adenosine in determining if there are areas of the heart not getting enough oxygen when blood flow to the heart is increased.

The primary objective of this study is to establish a cut off level of platelet inhibition that separates patients with or without previous stent occlusion with acute clinical onset while on aspirin and clopidogrel treatment within 6 months after coronary stenting for coronary artery disease.

Not infrequently, a physician is faced with uncertainty regarding the ability of a patient to perform adequate exercise in the noninvasive evaluation of known or suspected coronary artery disease (CAD) by the use of radionuclide stress myocardial perfusion imaging. In selected patients, protocols that combine exercise (either low-level or symptom-limited) with vasodilator stress agents have been found to be safe and effective in both identification of the presence and severity of CAD as well as risk stratification for adverse cardiac outcome. However, currently utilized combined stress protocols have drawbacks. Further refinement of combined stress protocols would potentially lead to more appropriate stress protocol selection for patients while enhancing laboratory efficiency. The purpose of this prospective, randomized study will be to evaluate the relative merits of combining regadenoson with symptom-limited exercise in patients clinically-referred for vasodilator-exercise stress myocardial perfusion imaging for the assessment of known or suspected CAD. It is hypothesized that combining regadenoson with symptom-limited exercise is a safe and feasible stress testing modality which is non-inferior to that which combines symptom-limited exercise with dipyridamole.

Since diabetic platelets are characterized by an enhanced turnover rate, it may be hypothesized that an increase in the frequency, rather than the dose, of drug administration may be a more effective strategy to inhibit platelet reactivity in diabetic patients as this may enable COX-1 blockade of newly generated platelets. However, how different dosing regimens impact the pharmacodynamic effects of aspirin selectively in diabetes mellitus has been poorly explored. Therefore, the aim of the present pilot investigation was to evaluate how increasing the frequency of aspirin administration, remaining within the daily recommended therapeutic doses, affects antiplatelet responsiveness in diabetic patients with coronary artery disease.

Background: Influenza vaccination is recommended in patients (pts) with cardiovascular disease, however there is a shortage of clinical studies proving its protective effect on clinical course of coronary artery disease (CAD). The aim of the study was to evaluate the effect of influenza vaccination on the incidence of coronary events in pts with CAD confirmed by coronary angiography.
