Filter by:To understand how depression leads to congestive heart failure (CHF) in older adults.
To investigate whether soy food intake reduces risk of non-fatal myocardial infarction (MI) and fatal coronary heart disease in Chinese women.
The purpose of this study is to see if 40 mg of rosuvastatin taken daily will reduce the atherosclerosis (fatty deposits) in your arteries
Testosterone has traditionally been regarded as a risk factor for heart disease due to the fact that males have a higher incidence of this disease than women, at least until the menopause. However recent studies have shown that men with low levels of testosterone may be at an increased risk of developing coronary heart disease (furring up of the blood vessels supplying blood to the heart). Our group has demonstrated a relaxing effect of testosterone in isolated animal coronary arteries (blood vessels supplying blood to the heart). We have shown that short-term testosterone administration can increase coronary artery and brachial artery (blood vessel in the arm) blood flow and can decrease the lack of blood supply to the heart muscle in men with coronary artery disease. These findings indicate a need for similar but longer-term studies to investigate the possible beneficial effects of longer-term testosterone therapy on the heart and blood vessels. Should this treatment be shown to be beneficial to men with coronary artery disease it may be a useful additional therapy for men with the furring up of arteries in the heart and the resulting angina. Aim To investigate our hypothesis that testosterone can beneficially affect myocardial perfusion, vascular reactivity, metabolic risk factors for coronary heart disease and improve quality of life in men with low plasma testosterone levels and coronary heart disease.
Abnormal blood cholesterol levels increase the risk of developing, or dying from heart disease. It is well recognised that if "harmful" LDL cholesterol is high, and "protective" HDL cholesterol is low, this risk is increased. Drugs called statins are routinely used in patients with heart disease, are well tolerated, and decrease the harmful LDL cholesterol levels. However, statins only increase protective HDL cholesterol to a small extent. Some patients may thus benefit from additional medication to increase protective HDL-cholesterol further. One of the most effective drugs which can do this is nicotinic acid. This drug is well established having been available for over 30 years. Previous use has been limited by facial flushing in a large percentage of patients receiving the drug. However a new formulation called Niaspan is now available which is associated with much less flushing. Although many patients will have transient flushing, it is estimated that only 1 patient out of every 20 receiving the drug will have to discontinue treatment. We therefore propose, in patients with coronary artery disease and low HDL cholesterol despite being on a statin, to study the effect of Niaspan on HDL cholesterol and other lipid parameters, and to assess its tolerability.
The purpose of this study is to compare the efficacy between two lipid lowering treatments, rosuvastatin (10-40 mg) and atorvastatin (20-80 mg) in reducing low-density lipoprotein cholesterol (LDL-C) levels after 16 weeks of treatment in patients with coronary heart disease
Conventional open vein harvesting from the legs during coronary artery bypass surgery result in wound complications among 30% of the patients. Endoscopic harvesting decrease the complication rate, but it remains to be shown whether this is also a fact among patient in whom only short segments of veingraft material is needed from the leg. We hypothesise that the rate of wound complications will be reduced and the patient satisfaction will be increased also among patients in whom only short vein segments are endoscopically harvested compared to conventional open vein harvesting.
The purpose of this study is to determine whether intracoronary bone marrow transplantation can improve left ventricular ejection fraction in patients with severe ischemic heart failure and no other option for standard therapies (revascularization and drugs).
The main objective is to compare the effectiveness of coronary stent implantation using the sirolimus-eluting Bx VELOCITY™ balloon expandable stent with that of surgery as observed in ARTS I. Effectiveness is measured in terms of Major Cardiac and Cerebrovascular Events (MACCE) free survival at 1 year.
The main objective of this study is to assess the safety and effectiveness of the sirolimus-coated Bx VELOCITY™ stent in maintaining minimum lumen diameter in de novo native coronary artery lesions as compared to the uncoated Bx VELOCITY balloon-expandable stent. Both stents are mounted on the Raptor® Rapid Exchange Stent Delivery System.
