Active clinical trials for "Coronary Artery Disease"

The purpose of this study is to compare the 2-year cardiac outcomes for women with limited exercise capability based on the resuls of either pharmacological stress myocardial perfusion imaging or a combined protocol that incorporates both exercise and pharmacological stress. The goal of the study is to compare these two methods for patient tolerability, safety and prognostic value

The purpose of this study is to determine whether percutaneous coronary angioplasty with Taxus drug eluting stent is safe and effective in the treatment of unprotected left main coronary artery disease associated to other coronary lesions or not.

The purpose of this study is to compare the safety and efficacy of fenofibric acid (ABT-335) + simvastatin combination therapy with ABT-335 and simvastatin monotherapy in subjects with multiple abnormal lipid levels in the blood.

The purpose of this study is to determine whether bivalirudin given during PCI is associated with better outcomes compared to un-fractionated heparin.

Previous clinical investigations have demonstrated the utility of β-adrenergic blockade in reducing perioperative ischaemic events, ultimately translating into a decrease in cardiac morbidity and mortality. However, β-blocker therapy remains underutilized in clinical practice because of concerns of potential adverse effects such as a reduced inotropic state, which might result in acute congestive heart failure or hypotension. Therefore, additional treatment with a positive inotropic agent might be needed. Phosphodiesterase inhibitors (PDEIs) offer a favourable pharmacological profile in this setting and stimulate cardiac function in the absence of the β-adrenergic receptor. We hypothesize that the combination of PDEI and β-blocker therapy would decrease perioperative plasma concentrations of brain natriuretic peptide (BNP) in patients requiring major vascular surgery. BNP is chosen as our primary outcome variable because of its importance as a sensitive correlate of myocardial dysfunction and its prognostic value for predicting the risk of cardiac death across the entire spectrum of acute coronary syndromes.

The main objective of this study is to assess the safety and effectiveness of the sirolimus coated Bx VELOCITY stent in reducing angiographic in-stent late loss in de novo native coronary lesions as compared to the bare metal Bx VELOCITY balloon-expandable stent. Both stents will be mounted on the Raptor Rapid Exchange Delivery Stent System.

This study will combine coronary stenting with minimally invasive robotic coronary bypass surgery, accomplished with the use of the da Vinci robot, to restore blood flow to occluded coronary arteries. Two previously approved and commonly performed procedures used to treat coronary artery disease(coronary stenting and robotic bypass surgery) are being combined into a hybrid surgery in a specialty built operating room. Patients with low risk coronary lesions will undergo cardiac hybrid revascularization using stenting and LIMA to LAD robotic bypass concomitantly. Patients' postoperative bleeding rates, angiographs and complication free rates will be recorded.

Context: Sirolimus-eluting stents and paclitaxel-eluting stents, as compared with bare-metal stents, reduce the risk of restenosis. It is unclear whether there are differences in safety and efficacy between the two types of drug-eluting stents. Objective: To determine differences in safety and efficacy between sirolimus and paclitaxel eluting stents.

Effects of AT1 receptor antagonist telmisartan on the primary endpoint inflammatory parameters in patients with coronary artery disease (CAD). Secondary endpoints are alterations in clinical course and blood pressure

The objectives of the study are to test the hypothesis that external counter pulsation therapy (ECPT) provides clinical benefit by improving the number and function of endothelial progenitor cells (EPCs) in peripheral blood of patients with angina pectoris.
