Filter by:This evaluation is designed to evaluate the feasibility of using an automated distal coronary anastomotic to facilitate grafting of the left internal mammary artery to the left anterio descending coronary artery during myocardial revascularization in patients with coronary artery disease requiring surgical intervention. The study is designed to assess the ability to compare the patency of grafts created using an automated device versus hand-sewn grafts of the same vessels in the same patient population.
Impaired contractile function after a heart attack and due to coronary heart disease is a major cause of "heart failure" limiting quality of life and prognosis, which cannot be prevented even with optimal standard therapy. The aim of the current trial is to investigate whether infusion of progenitor cells into the coronary artery supplying the most dyskinetic left ventricular area may improve left ventricular contractile function, compared to no cell infusion in the control group, in patients with old (>= 3 months) myocardial infarction.
The objective of our research is to determine whether treatment with magnesium will reduce the incidence of atrial fibrillation in patients undergoing cardiac surgery. Several small studies of magnesium have already been conducted, but these studies were small and the results conflicting. A large, well-conducted study of magnesium treatment is required to definitively determine whether magnesium is effective in preventing this common complication after surgery. In addition, our study will include patients undergoing valvular surgery, a group previously excluded from research despite the fact that they are at increased risk of atrial fibrillation.
The process of re-narrowing of a coronary artery following a revascularization procedure such as angioplasty, begins at the time of the procedure. Restenosis has long been considered a major problem for effective long-term interventional success. This often results in repeated procedures to deal with recurrent stenosis (or restenosis) of the original targeted vessel. There is a substantial body of literature suggesting that local MYC protein production in the injured coronary artery is a major stimulus and potential cause of restenosis that appears after stent placement. This study is based upon the hypothesis that stopping MYC protein production in the vessel has will help reduce restenosis (vessel re-narrowing). AVI BioPharma Inc., has utilized its proprietary antisense chemistry to design a drug that interferes with MYC production. This study will evaluate the safety, pharmacokinetics and potential effectiveness of a single intravenous slow-push dose of RESTEN-MP at the time of stent placement to reduce in-stent restenosis following balloon angioplasty and stent placement. The post-dose follow-up period is up to six-months.
Despite the effectiveness of beta-blockers and antiplatelet agents for secondary prevention of coronary heart disease, this treatments are underused in the elderly because of diagnosis uncertainty and underuse of efficient treatment. in a first time, diagnosis reassessment with invasive technique if necessary. in a second time, treatment reassessment.
The purpose of this study is to determine if stem cell therapy with your own cells (autologous cells) delivered with a catheter to regions of the heart with poor blood flow will be safe and if it will relieve your chest pain, increase the blood flow, and/or improve the cardiac contractility (function) by regenerating blood vessels in your heart.
The purpose of this study is to examine the relationship between depressive symptoms and markers of inflammation, two predictors of heart disease.
The aim of this study is to determine in high risk diabetics if the positive predictive value of stress echocardiography is superior to the positive predictive value of stress scintigraphy in the diagnosis of coronary stenosis > 50%.
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 VENEK trial is a randomized, prospective trial to compare economic parameters, quality of life and wound healing after endoscopic vein harvesting versus open vein harvesting.
