Filter by:The purpose of ZEST-LATE (Evaluation of the Long-term Safety After Zotarolimus-Eluting Stent, Sirolimus-Eluting Stent, or PacliTaxel-Eluting Stent Implantation for Coronary Lesions - Late Coronary Arterial Thrombotic Events) trial is to assess the relationship between long-term clopidogrel use beyond 1 year and long-term rates of death or MI after DES implantation and to estimate the duration of dual antiplatelet therapy for preventing the late thrombotic events.
To evaluate whether the cilostazol reduce neointimal hyperplasia after ZES (Zotarolimus-eluting stents) implantation, the investigators performed double-blind,randomized, multicenter, prospective study compared triple antiplatelet therapy (aspirin plus clopidogrel plus cilostazol) and dual antiplatelet therapy (aspirin plus clopidogrel) for 8 months in patients with long coronary lesion treated with ZES.
It is recommended that patients who have drug-eluting stents placed in their coronary arteries take aspirin and Plavix (Clopidogrel) for at least a year. Patients who stop taking these antiplatelet drugs or who have resistance to the antiplatelet effects of these drugs are at a higher risk of clots occurring inside the stents which may result in a heart attack. At the present time, it is unknown if increasing the doses of the antiplatelet agents is effective in overcoming this resistance. The purpose of this project is to identify patients with antiplatelet drug resistance and to test whether an increase in the Plavix (Clopidogrel) dose overcomes antiplatelet drug resistance.
To evaluate that angiotensin-converting enzyme (ACE) inhibitors and angiotensin-converting enzyme receptor blockers (ARBs) reduce the risk of restenosis after DES implantation.
The goal of this study is to determine if one dose of simvastatin will decrease the inflammatory response to coronary intervention. Also to determine if one dose of simvastatin affects endothelial function (activity of the artery) as measured by noninvasive peripheral artery tonography.
The purpose of this study is to: - evaluate the performance characteristics (sensitivity & specificity) of iodofiltic acid I-123 imaging for detection of myocardial ischemia in patients that present in the Emergency Department with suspected Acute Coronary Syndrome (ACS). - evaluate the safety of a single injection of iodofiltic acid I-123 in patients suspected of myocardial ischemia related to ACS.
The purpose of this study is to determine if the use of PB127 with cardiac ultrasound assists in the diagnosis or exclusion of coronary artery disease.
The purpose of this study is to determine the dose of PB127 for detection and/or exclusion of coronary artery disease when used with cardiac ultrasound. This study also evaluates the safety of PB127.
The purpose of this study is to collect longer term follow-up information concerning health and survival on selected patients who received PB127 for injectable suspension in the pivotal trial (127-014).
The goal is to determine if prehydration based on LEVDP is superior to a standard hydratation with NaCl 0.9% or NaHCO3 for the prevention of contrast nephropathy related to a diagnostic coronary angiogram or to PCI.
