Filter by:The primary objective of the PRE-COMBAT trial is: To establish the safety and effectiveness of coronary stenting with the sirolimus-eluting balloon expandable stent (Cordis Johnson & Johnson, Warren, New Jersey) compared with bypass surgery for the treatment of an unprotected LMCA stenosis. The alternative hypothesis is that the experimental strategy (coronary stenting with the sirolimus-eluting stents) is not inferior to the standard strategy (bypass surgery).
This study is designed to evaluate the performance and safety of a new catheter system.
Patients who have stents placed in their coronary arteries require treatment with at least two medications to prevent platelets from sticking to the stainless steel stent and forming a blood clot that can result in a heart attack. The 2 anti-platelet medications used for most patients with stents are aspirin and clopidogrel (Plavix). These are usually prescribed for 1-12 months (the length of time depends on the number and types of stents implanted). Although the typical long-term dose of clopidogrel is 75 mg by mouth once daily, a larger dose (known as a loading dose) is usually given at the start of treatment to help the medication take effect more quickly. Prior to January 2006, most patients at the Beth Israel Deaconess Medical Center (BIDMC) who were undergoing PCI and who had not already been taking clopidogrel would receive a loading dose of 300-600 mg of clopidogrel in the cardiac catheterization procedure room immediately after the angioplasty and stenting portion of the procedure. However, several recent studies suggest that administering clopidogrel 600 mg at least two hours prior to an angioplasty procedure can reduce the rate of complications afterwards (especially reducing the chances of detectable damage to the heart muscle). The main purpose of this study is to see whether giving a loading dose of clopidogrel 600 mg to outpatients scheduled to undergo cardiac catheterization with coronary angiography can decrease the risk of procedure-related complications during the 14 days following the cardiac catheterization compared to a strategy of giving clopidogrel 600 mg after the procedure only to those who undergo angioplasty. We will focus our attention particularly on detecting damage to heart muscle following angioplasty (which might be expected to improve with a loading dose of clopidogrel before the procedure) and on bleeding and other groin complications (which might worsen with clopidogrel loading before the procedure). The drug clopidogrel has been approved by the Food and Drug Administration (FDA) for use in patients with a recent or ongoing heart attack, narrowings in major blood vessels outside the heart, or recent stroke with a loading dose of 300 mg followed by 75 mg once daily. It has been used in several large studies with a loading dose of 600 mg without a significant increase in major adverse effects. However, we do not yet know if it is useful or safe when given as a loading dose of 600 mg before cardiac catheterization for outpatients with stable symptoms and who are not thought to be in the midst of a heart attack.
The purpose of this study is to determine whether a paleolithic diet improves glucose tolerance and insulin sensitivity in people with coronary heart disease and impaired glucose tolerance.
This study aimed to evaluate the efficacy and safety of escitalopram in the treatment of depressive patients with acute coronary artery syndrome (CAS).
To determine the safety and feasibility of same day discharge after elective coronary percutaneous intervention in a selected stable patient population. The hypothesis to be tested is that in an appropriately selected stable coronary artery disease population post percutaneous coronary intervention, early discharge is safe and feasible.
The purpose of this study to determine whether the dual antiplatelet therapy (aspirin and clopidogrel) for 3 months after coronary implantation of zotarolimus-eluting stent is safe in terms of death, myocardial infarction, or stent thrombosis.
This is a prospective double blind trial of intraoperative transmyocardial bone marrow−derived mesenchymal cell transplantation vs placebo in patients with low left ventricular ejection fraction scheduled to coronary bypass operation.
The purpose of this study is to establish the safety and long-term effectiveness of coronary stenting with the ABT 578-eluting balloon expandable stent (Medtronic, Minneapolis, MN) vs. the sirolimus-eluting balloon expandable stent (Cordis Johnson & Johnson, Warren, New Jersey) and the paclitaxel-eluting stent (Taxus liberte, Boston Scientific) for the treatment of coronary stenosis in routine clinical practice.
Chronic Heart Failure Analysis and Registry in the Tohoku District 2 (CHART-2 Study) is a large, prospective, hospital-based cohort study to investigate the following: - Characteristics of patients with chronic heart failure and prognostic risks of these patients. - Characteristics of patients with high risk for heart failure and critical factors which predict the development of symptomatic heart failure in these patients. - The incidence and prognostic impact of metabolic syndrome in patients with chronic heart failure. - The association between metabolic syndrome and the development of symptomatic heart failure.
