Filter by:Not infrequently, a physician is faced with uncertainty regarding the ability of a patient to perform adequate exercise in the noninvasive evaluation of known or suspected coronary artery disease (CAD) by the use of radionuclide stress myocardial perfusion imaging. In selected patients, protocols that combine exercise (either low-level or symptom-limited) with vasodilator stress agents have been found to be safe and effective in both identification of the presence and severity of CAD as well as risk stratification for adverse cardiac outcome. However, currently utilized combined stress protocols have drawbacks. Further refinement of combined stress protocols would potentially lead to more appropriate stress protocol selection for patients while enhancing laboratory efficiency. The purpose of this prospective, randomized study will be to evaluate the relative merits of combining regadenoson with symptom-limited exercise in patients clinically-referred for vasodilator-exercise stress myocardial perfusion imaging for the assessment of known or suspected CAD. It is hypothesized that combining regadenoson with symptom-limited exercise is a safe and feasible stress testing modality which is non-inferior to that which combines symptom-limited exercise with dipyridamole.
Cardiovascular disease (CVD) remains the major cause of mortality and morbidity in both type 1 (T1D) and type 2 (T2D) diabetes patients; modifications of traditional CVD risk factors have had a limited impact. This project called Regadenoson Blood flow in Type 1 Diabetes (RABIT1D) and is proposed as a sub-study of the Coronary Artery Calcification in Type 1 Diabetes (CACTI) study, which has established a unique cohort of 656 T1D patients (age 20-55, minimal diabetes duration of 10 yrs) and 764 non-diabetic controls. This cohort is being followed for progression of coronary artery calcification (CAC) measured using the electron beam tomography (EBT) for development of clinical CVD. Participants have been well characterized during the baseline examination (4/00-3/02) and two follow-up re-examinations 3 and 6 years later. The study has provided important insights into the risk factors and possible prevention of premature CVD in T1D. We are proposing assess a subset of this population to determine vasodilatory reserve as it relates to early coronary atherosclerosis in T1D. Hypothesis: that myocardial blood imaging (MBF) reserve can be measured in Type 1 diabetes mellitus (DM) using regadenoson stress cardiac magnetic resonance and that significantly reduced MBF is a marker of extensive atherosclerotic disease correlated to coronary arterial calcification, plaque formation and impaired vasodilatory reserve.
The purpose of this study is to compare women's cardiac rehabilitation program adherence across three program models.
To determine if prasugrel is superior to clopidogrel in providing adequate antiplatelet effect in a high risk population that requires concomitant use of a Proton Pump Inhibitor (PPI).
The present study constitutes a study examining the effect of atorvastatin on vascular function in high cardiovascular risk patients. For this purpose the investigators will record atorvastatin effects on statin-naïve patients (patients that start statins treatment for first time). More specifically the investigators will study atorvastatin effects on: 1. Endothelial function 2. Arterial elastic properties 3. Systemic Inflammatory/thrombotic mechanisms 4. Vascular and myocardial redox state
The purpose of this study is to determine the impact of adjunctive cilostazol versus high maintenance-dose clopidogrel on platelet inhibition in carriers and non-carriers of the loss-of-function CYP2C19 mutant allele.
The study drug bIAP, or matching placebo, will be administered as a bolus of 1000 Units bIAP or matching placebo prior to anaesthesia (T = -15 minutes), directly followed by intravenous continuous infusion of about 5.6 units per kg bodyweight/hr at pump rate 4 ml/hr for approximately 36 hrs (total 200 IU/kg/36 hrs) into each of a total of 50 patients scheduled for coronary artery bypass graft surgery (CABG). Risk of surgical complications and mortality due to co-morbid conditions will be collected and the EuroSCORE will be used to screen patients prior to surgery.
Randomized study. Patients with coronary artery disease equivalent will be randomized to receive atorvastatin 40 mg/day + placebo vs. atorvastatin 40 mg/day + ezetimibe 40 mg/day. Oxidized LDL cholesterol will be measured at baseline and after 8 weeks of treatment. Hypothesis is that ezetimibe will lower oxidized LDL
The purpose of this study is to assess whether the new Kaname coronary stent is safe and effective for the treatment of patients with coronary artery disease.
The purpose of the study is to evaluate the safety and efficacy of catheter mediated endocardial adenovirus VEGF-D gene therapy in patients with severe coronary heart disease.
