Filter by:Clopidogrel and statins are frequently coadministered in patients with ischemic heart diseases. Recent reports suggested that clopidogrel's effectiveness in inhibiting adenosine diphosphate (ADP)-induced platelets aggregation is attenuated by co-administration of certain statins. The objective of the present study is to define which kind of statins might interfere with the antiaggregation property of clopidogrel in patients with acute coronary Syndrome after percutaneous coronary intervention (PCI). In this prospective randomized study, all patients in test group will receive clopidogrel plus atorvastatin, and all patients in control group will receive clopidogrel plus pravastatin. All patients will be followed up for one year. The primary endpoints include death, non fatal AMI, urgent revascularization. The secondary endpoints include hemorrhage events and subacute thrombosis events at 1 year.
Effects of dual antiplatelet therapy with aspirin and clopidogrel after percutaneous coronary intervention has been proven. However, patients with low response to those agents are reported be associated with adverse clinical outcomes. We suppose that optimized antiplatelet therapy for individual patients based on platelet function assay may improve long-term outcomes especially in patients with high risk of thrombosis. In this prospective randomized study, patients in control group all receive standard dual antiplatelet therapy, and patients in optimized group receive different antiplatelet therapy according to risk stratification.
Estimating the risk of future cardiovascular events such as death, stroke and myocardial infarction using traditional risk factors (such as age, gender, smoking, diabetes, hyperlipidaemia and hypertension) is well accepted in patients with and without existing cardiovascular disease. These estimates are based on a number of robust observational studies, including the original Framingham study. While these methods apply reasonably well on a population level their application to the individual patients is not always straightforward. In addition, risk charts, such as those published by the Joint British Societies and American Heart Association, may underestimate risk in certain groups, notably diabetics and patients of Indo-Asian background, whilst overestimating risk in others (by as much as 50% in some studies).
Heart transplanted patients often develop coronary artery disease and therefore have their coronary arteries examined with coronary angiography once a year.The purpose of the study is to validate computer tomography of the coronary arteries against coronary angiography and intravascular ultrasound in heart transplanted patients. Additionally the association between different inflammatory markers and the development of CAD specific to heart transplanted patients will be studied.
Coronary heart disease (CHD) is the leading cause of death in the United States. One common risk factor for CHD is obesity. The presence of certain types of fat over others is more commonly associated with the development of CHD. This study will use data from a previous study to examine the association between pericardial fat, a type of fat that surrounds the heart, and CHD.
The purpose of this study is to evaluate whether adding estradiol to rapamycin better prevents coronary artery reblockage after drug-eluting stent implantation.
The purpose of this study is to determine the effect of MC-1 on the combined incidence of cardiovascular death and nonfatal myocardial infarction (MI) up to and including 30 days following coronary artery bypass graft (CABG) surgery compared with placebo.
The purpose of this Clinical Evaluation is a continuation in the assessment of the performance of the XIENCE V® Everolimus Eluting Coronary Stent System (XIENCE V® EECSS) in the treatment of patients with de novo coronary artery lesions.
This 2 arm study will assess the long term safety and efficacy of RO4607381 in patients with coronary heart disease or a coronary heart disease (CHD) risk equivalent who have completed study NC19453. Patients eligible to participate in the extension study will continue on the treatment they were originally assigned to ie RO4607381 (900mg po) or placebo daily, with concomitant daily atorvastatin (10 to 80mg po). The anticipated time on study treatment is 6 months post study NC19453, and the target sample size is approximately 100 individuals.
During coronary artery bypass graft surgery, injury occurs to the heart muscle. Some of this injury is due to the deprivation of oxygen and nutrients to the heart (a process called ischemia) during the surgery itself. The objective of this study is to examine whether remote ischaemic preconditioning (RIPC), in which the application of transient ischemia to the forearm and thigh (through the inflation of blood pressure cuffs placed on the right upper arm and upper thigh) may reduce the injury to the heart muscle sustained during cardiac surgery. The study hypothesis is: remote ischemic preconditioning will protect the heart and improve short-term clinical outcomes during coronary artery bypass graft surgery.
