Filter by:This is an observational study among Latino patients who have coronary artery disease. The goal of the study is to determine the association between having depressive symptoms and the ability to modify one's health behavior. Specifically, participate in physical activity.
The purpose of this study is to compare two ways to treat patients with Type 2 Diabetes, Standard Care or Case-Managed Care. In-Patient Standard Care is guided by the assigned cardiologist and Out-Patient Standard Care by the existing diabetes care givers. Case-Managed care involves a consult with an endocrinologist and counseling from a diabetic educator and a dietician.
To evaluate the clinical safety, efficacy, and pharmacokinetics (PK) of the Endeavor Resolute Zotorolimus Eluting Coronary Stent System for the treatment of single de novo lesions in native coronary arteries with a reference vessel diameter (RVD) between 2.5 and 3.5 mm in diameter.
The process of re-narrowing of a coronary artery following a revascularization procedure such as angioplasty, begins at the time of the procedure. Restenosis has long been considered a major problem for effective long-term interventional success. This often results in repeated procedures to deal with recurrent stenosis (or restenosis) of the original targeted vessel. There is a substantial body of literature suggesting that local MYC protein production in the injured coronary artery is a major stimulus and potential cause of restenosis that appears after stent placement. This study is based upon the hypothesis that stopping MYC protein production in the vessel will help reduce restenosis (vessel re-narrowing). AVI BioPharma Inc., has utilized its proprietary antisense chemistry to design a drug that interferes with MYC production. This study will evaluate the safety and potential effectiveness of RESTEN-MP to reduce in-stent restenosis following balloon angioplasty and stent placement. The post-dose follow-up period is up to six-months. RESTEN-MP is administered at the time a stent is successfully placed in a coronary artery, and again 24 hours later, via slow-push intravenous administration.
There are many reports about the association of coronary artery disease (CAD) and cerebral artery stenosis (CAS), which had been proved to induce stroke and cognition decline after the revascularization including coronary bypass surgery (CABG) or percutaneous coronary intervention. Perfusion defect on nuclear brain scan is also noted to correlate with these neurological complications. On the other hand, the perioperative arrhythmia and following cerebral embolism was also attributed to be one factor inducing such neurological hazards. In the patients with coexistent CAD and CAS (1st group), and also the patients scheduled for CABG or percutaneous coronary intervention (PCI) (2nd group), we, the researchers at Far Eastern Memorial Hospital, attempted to integrate all the parameters mention above, including angiography of coronary and cerebral system, quantitative analysis of nuclear brain scan, biochemical profile, and signals of a new ambulatory device which could record the electrocardiograph (ECG) and electroencephalograph (EEG) simultaneously, in order to define the correlation between them. A chorological relation between EEG signals and ECG signals is our first target to be worked out. Thereafter, we hope to establish a regression model of all involved parameters according to the relation. Such a model, we believe, is essential not only to explain the post-CABG neurological complications, but to prevent them. Furthermore, for the undetermined ischemic stroke patients who had no obvious culprit artery or embolism source, the paroxysmal arrhythmia had long been regarded as the cause. Whether a paroxysmal atrial fibrillation, which had not been disclosed by routine ECG, could induce most of such a stroke is still not known. With this new ambulatory device which could record the electrocardiograph (ECG) and electroencephalograph (EEG) simultaneously, we want to answer the question.
The purpose of this PMS registry, named e-CYPHER Stent Registry, is to collect post marketing surveillance data on the CYPHERTM Sirolimus-eluting Coronary Stent following marketing approval, when used in normal clinical practice within the labeled indications.
Evaluation of skin cholesterol for cardiovascular risk assessment in asymptomatic individuals at low, intermediate, or high risk based on Framingham Global Risk estimates. Carotid intima-media thickness (IMT), a surrogate marker for atherosclerotic burden, that independently predicts the occurrence of heart attack and stroke, will be the “gold standard” comparator. Hypothesis: Skin cholesterol, as measured by two non-invasive tests, correlates with CAD, as measured by CIMT in this population.

To compare renal function (51Cr-EDTA clearance) 48 hours post open-heart surgery (coronary bypass or valve surgery) in patients with impaired renal function after randomization to either nifedipine infusion at start of surgery and the following 24 hours or placebo (0.9% saline infusion). Study hypothesis is that nifedipine has a prophylactic effect on decline in renal function.
The purpose of this study is to determine the effect of an antidepressive medication (Escitalopram), started preoperatively and given during 6 months, on 6-month and 1 year post-operative morbidity and mortality after coronary artery bypass grafting
