Filter by:Objectives: Evaluate differences for mortality, morbidity and the cardiovascular risk factors between HIV and non-HIV patients with an acute coronary syndromes (ACS) after a 3-years follow up.
The purpose of the study was to evaluate procedural and late outcome of coronary artery stenting using 2 different unmounted stents
The purpose of this study is to determine whether the radial artery (artery in the arm) or saphenous vein (vein in the leg), when used as bypass grafts for coronary artery bypass surgery, have a greater patency rate (degree of opening)at 5 years after surgery.
Candesartan is effective in preventing cardiovascular events in patients without restenosis after coronary angioplasty. Therefore, the investigators hypothesized that candesartan after drug-eluting stent (DES) implantation was also effective in preventing cardiovascular events. The purpose of this study is to investigate whether an angiotensin II receptor blocker, candesartan, is effective in reducing the incidence of cardiovascular events after drug-eluting stent implantation.
The aim of this study was to evaluate the mobilization of non-haematopoietic mesenchymal and haematopoietic stem cells from the bone marrow with granulocyte colony stimulating factor (G-CSF) treatment alone and in combination with vascular endothelial growth factor (VEGF) gene therapy in patients with severe chronic occlusive coronary artery disease.
The purpose of this observational protocol is to evaluate the use of everolimus in routine clinical practice for heart transplants. Primary outcome measures: incidence of acute rejection episodes Secondary outcomes: safety
Coronary artery disease is the single most important killer of Canadians. Despite major advances in therapy, there is still a significant proportion of patients identified with the disease who die of it because current treatment approaches cannot effectively palliate their condition. A new treatment modality called therapeutic angiogenesis has appeared on the clinical research scene during the last five years; this approach recreates the natural processes of new blood vessel formation that is observed during growth and development in every human being. It is an extremely potent and promising modality, but so far the results of clinical trials in patients have been equivocal. One reason for the limited efficacy observed thus far with therapeutic angiogenesis may rest in that factors produced by the lining of the coronary arteries themselves are essential for angiogenic substances to take effect in the heart muscle of patients with severe coronary artery disease. These same patients, however, virtually all have, as a result of their disease, marked dysfunction of their coronaries and therefore fail to produce these factors in adequate quantities. This hypothesis has been verified with extensive animal data by the investigators of this research, where a swine model of coronary disease was shown to severely inhibit the action of angiogenic growth factors. If one wants angiogenesis to work, a means of improving the function of the coronary lining of patients with severe ischemic heart disease must be identified and its effects evaluated in order to allow for angiogenic substances to exert their action towards successful revascularization of the heart muscle. An amino acid called L-arginine has repeatedly been shown to markedly improve function of the coronary artery lining in patients with ischemic heart disease when administered regularly over a period of several months. This research will therefore test, in the form of a randomized clinical trial, whether this concomitant approach can make angiogenesis effective in patients with advanced coronary disease, by allowing for the action of growth factors to take place in the heart. If this approach is successful, as is anticipated, angiogenesis will constitute an effective modality for the treatment of coronary artery disease, not only in patients with advanced, severe involvement unamenable to any other form of cardiac therapy such as coronary artery bypass grafting, but even perhaps in all patients with coronary artery disease in need of revascularization. The goal of this investigation towards the making of a new, revolutionary, safe and efficacious modality for the treatment of the number one killer disease of Canadians is in complete agreement with the primary objective of the Heart and Stroke Foundation of Canada.
The Torcetrapib project was terminated on December 2, 2006 due to safety findings. To look at ultrasound images taken in the blood vessels of the heart and to look at various lipids in the blood of people with known coronary heart disease
Because blood pressure affects the heart, blood vessels, kidneys, and the entire body, it is important to keep it as normal as possible. There are several different ways to control blood pressure and to prevent or limit the development of heart disease due to high blood pressure. The purpose of this study is to compare two treatments to see how well they work and the difference in their side effects. One treatment includes the use of a calcium antagonist drug (Isoptin sustained release [SR] or Verapamil SR). The other treatment excludes the calcium antagonist and may include a non-calcium antagonist drug called a beta blocker (Tenormin or Atenolol). Both treatments may also include medication called angiotensin converting enzyme (ACE) inhibitors and water pills. None of the drugs in this study are experimental, they are all approved by the Food and Drug Administration (FDA).
The purpose of this study is to evaluate the efficacy of sirolimus- and paclitaxel-eluting stents for treatment of unprotected left main coronary artery disease.
