Filter by:The main objective of this study is to assess the safety and effectiveness of the sirolimus-eluting Bx VELOCITYTM stent in reducing in-lesion late loss in patients with de novo native coronary artery lesions.
The main objective of this study is to assess the safety and effectiveness of the sirolimus-eluting Bx VELOCITYTM stent in reducing in-lesion restenosis in patients with de novo native coronary artery lesions.
The objective of this study is to evaluate the effectiveness and safety of the CYPHER NxT Sirolimus-eluting Coronary Stent on the BX SONIC Over-the-Wire (OTW) Stent Delivery System (SDS) in patients with de novo native coronary artery lesions.
The objective of this study is to allow treatment with the sirolimus-eluting Bx VELOCITYTM stent in patients with a serious disease or condition for which there is no generally acceptable alternate treatment available.
COAT-platelets stands for collagen and thrombin stimulated platelets, which are two things in the body that make platelets stick together. These platelets may be important in the initiation of a heart attack (myocardial infarction). A chemical in the body called serotonin maybe responsible for COAT-platelet production. Paroxetine causes a significant reduction in platelet serotonin and therefore may have value in preventing heart attacks. Therefore, the current study is designed to determine whether paroxetine will decrease COAT-platelet production in normal volunteers and patients with cardiovascular disease.
The purpose of this study is to determine whether the combination of clopidogrel with aspirin prevents the development of blockages (atherosclerosis) in vein grafts one year after coronary artery bypass surgery (CABG) compared to aspirin alone.
Single nucleotide polymorphisms at codon 46 and 79 of the gene encoding for the ß2 adrenergic receptor (ß2AR) modify its pharmacological properties and may alter the response to ß2AR agonists. The goal of the present study was to evaluate the role played by the Arg16Gly and Gln27Glu polymorphisms on isoproterenol induced relaxation of internal mammary arteries segments ex-vivo. Internal mammary leftover segments were collected from 96 patients undergoing coronary artery bypass graft operation. Four rings that were prepared from each specimen were allowed to reach equilibrium with physiological Krebs solution prior to precontraction with U46619. Using the organ bath technique, cumulative dose response curve of isoproterenol was constructed and mean EC50 calculated for each patient.
The study is intended to collect data to evaluate effectiveness and safety of drug eluting stent devices in a dose ranging assessment.
This trial will compare the long term safety and effectiveness of the V Flex Plus PTX Drug Eluting coronary stent with conventional treatment for in-stent restenosis for coronary arteries.
ELUTES is a European multicenter, randomized, controlled, triple-blinded study designed to evaluate the ability of the Paclitaxel Eluting V-Flex Plus coronary stent to reduce restenosis in the coronary artery.
