Filter by:Context: Sirolimus-eluting-stents have improved the benefits of percutaneous interventions in native coronary arteries reducing the occurrence of restenosis and repeated revascularization, however saphenous vein grafts have been always excluded form randomized trials. Objective: To evaluate the angiographic and clinical impact of sirolimus-eluting-stents with respect to bare-metal-stents in degenerated vein grafts. Design: Double-blind randomized controlled non-industry-sponsored trial. Setting: A single-center tertiary-care referral hospital. Patients: All patients are randomly allocated to sirolimus-eluting-stent implantation or the corresponding bare-metal-stent. All patients are followed clinically and repeated angiographic follow-up is performed in all at 6-months. Main outcome measure: Primary end-point is 6-months angiographic in-stent late loss. Secondary end-points include: binary angiographic in-stent and in-segment restenosis, intravascular-ultrasound-measured neo-intimal hyperplasia volume and all the clinical events (death, myocardial infarction, target-lesion and target-vessel revascularization).
The primary purpose of this study was to compare the efficacy and safety of bivalirudin to eptifibatide (with or without unfractionated heparin or enoxaparin)given to subjects at high risk for heart attack and other cardiovascular complications who will undergo surgery to open up blocked arteries in the heart.
The purpose of this study was to test the hypothesis that the long-term use of highly (＞98%) purified EPA, in addition to HMG-CoA reductase inhibitor (statin), would be more effective than statin alone in preventing cardiovascular events in Japanese patients with hypercholesterolemia.
In a randomized, controlled clinical trial, point-of care testing at the bedside using the cardiac biomarker troponin I in ED patients with possible ACS will be compared to traditional testing of this assay for myocardial necrosis obtained in the central laboratory. Our hypothesis: point-of-care testing for troponin I will decrease the time for disposition of patients with possible ACS in the emergency setting and decrease the time required for administering appropriate therapies for these patients.
The purpose of the research is to determine the best automated external defibrillator (AED) training approach for high-risk patients and their family members with regard to AED skills retention and psychological adjustment.
The purpose of the study is to test the efficacy and safety of bupropion SR for smokers hospitalized with acute cardiovascular disease.
A magnetocardiograph (MCG) is a device capable of recording of magnetic fields arising from the electrical activity of the heart with traces similar to an electrocardiogram (ECG). This system was developed as a noninvasive, non-contact diagnostics of obstructive coronary artery disease (CAD), and especially of lack of oxygen in the heart as in a heart attack. The overall objective of this study is to demonstrate the efficacy of this MCG device for the detection and diagnosis of lack of oxygen of the heart in patients with chest pain.
The purpose of the study was to evaluate procedural and late outcome of coronary artery stenting using 2 different unmounted stents
The purpose of this study is to determine whether there is any additional benefit from abciximab administration during percutaneous coronary intervention in patients presenting with acute coronary syndromes after pre-treatment with 600mg of clopidogrel.
The purpose of this study is to test whether SR123781A is a possible treatment for patients with acute coronary syndromes (heart attack) who are scheduled to undergo a percutaneous coronary intervention (PCI) within 48 hours after inclusion in the study. Two doses of SR123781A are currently tested, each in a group of about 180 patients per group to find which is the most adequate, versus heparin and glycoprotein IIbIIIa (GPIIBIIIA) antagonist.
