Adequate platelet inhibition before percutaneous coronary intervention (PCI) reduces peri-procedural and long-term ischemic complications. Documented reduced response to clopidogrel has been associated with subsequent major adverse cardiovascular events. Strategies to optimize platelet inhibition pre-PCI are under investigation. This study sought to evaluate the effect on platelet aggregation of four different dosing regimens of clopidogrel given before elective PCI.
A retrospective cohort study performed in the GPRD,UK. All patients with incident prostate cancer identified between 1 Jan 1999 and 31 Dec 2005 and a frequency-matched cohort of the general population will be followed- up for two outcomes; CHD including acute myocardial infarction or death from coronary heart disease and HF until Dec 31, 2006. Outcomes will be validated through requests to primary care physicians. Incidence rate´ratios of CHD and HF in the two cohorts will be calculated. In the cohort of prostate cancer the relative risk of CHD and HF associated with the use of bicalutamide compared to non-use will be estimated.
The purpose of this study is to evaluate a new angioplasty catheter, AngioSculpt® for the treatment of bifurcation lesions (blockages occurring at branch points) in coronary arteries.
This study will evaluate the efficacy of anacetrapib (100 mg) for 24 weeks relative to placebo, on plasma concentrations of Low Density Lipoprotein Cholesterol and assess the safety and tolerability of anacetrapib (100 mg) in participants with CHD/CHD risk-equivalent disease on stable dose regimen of statin with or without other lipid-modifying therapy. The two year extension to this study will further evaluate the long-term safety profile and efficacy of anacetrapib in CHD/CHD-risk equivalent patients who are on ongoing therapy with a statin with or without other lipid-modifying therapy.
Single center randomized parallel group study to determine if: 1. there is a temporary increase in platelet reactivity after abrupt discontinuation of clopidogrel due to a potential rebound phenomenon. 2. the effect of sudden discontinuation of clopidogrel 6 months post coronary angioplasty with adjunct drug eluting stent implantation compared to 12 month continuation of clopidogrel on platelet reactivity. And the association with MACE up to 12 months post coronary angioplasty.
Study hypothesis: Multifactorial risk reduction in coronary heart disease can reduce the risk of new coronary heart disease and death
XIENCE V USA is a prospective, multi-center, multi-cohort post-approval study. The objectives of this study are - To evaluate XIENCE V EECSS continued safety and effectiveness during commercial use in real world settings, and - To support the Food and Drug Administration (FDA) dual antiplatelet therapy (DAPT) initiative. This initiative is designed to evaluate the composite of all death, myocardial infarction (MI) and stroke (MACCE) and the survival of patients that are free from Academic Research Consortium (ARC) definite or probable stent thrombosis (ST) and that have been treated with drug eluting stents (DES) and extended dual antiplatelet therapy.
This study is being done to see if the blood pressure lowering effect of an approved drug nebivolol is comparable to that of another approved drug carvedilol for the treatment of hypertension in patients who have coronary artery disease.
The well established importance of regular aspirin administration stands on firm grounds, as large meta-analyses have shown this therapy to significantly reduce the risk of death. However, not all patients benefit of aspirin administration to the same extent, thus high-lighting a sub-population of patients with inadequate platelet response to ASA. The mechanisms underlying reduced ASA efficacy remain elusive. A recent report has suggested that platelets, long believed to be incapable of de novo protein synthesis, may retain their ability to form the cyclooxygenase enzyme, once it has been inactivated by aspirin. This may explain the inefficacy of the drug to induce sustained platelet inhibition in certain patients. The current study aims to evaluate, in patients suffering from stable coronary artery disease, the stability of platelet inhibition by aspirin during the normal once daily dosing regimen.
