Age and Endothelial Progenitor Cell Mobilization
Coronary Artery DiseaseIt is hypothesized that aging is associated with reduced vascular injury-induced endothelial progenitor cell activity, resulting in impaired vascular repair and increased vascular disease. Patients with stable coronary artery disease will be enrolled in this observational study and will undergo either angiography alone or angiography and angioplasty. Participants will be followed for 5 years.
Randomized, Two-arm, Non-inferiority Study Comparing Endeavor-Resolute Stent With Abbot Xience-V...
Coronary Artery DiseaseThe RESOLUTE-III Allcomers trial is a prospective, multicenter, randomized, two-arm, international, non-inferiority, open-label study with 2300 patients at 15-20 centers. The study is a "real world, all comers" study. Primary objective: to compare the Medtronic Endeavor-Resolute (Zotarolimus-Eluting stent) system with the Abbott XIENCE V (Everolimus-Eluting stent) system with respect to cardiac death, myocardial infarction (not clearly attributable to a non-target vessel), Target Lesion Revascularization at 1 year in a "real world" patient population.
Predictor of Advanced Subclinical Atherosclerosis
Coronary Artery DiseaseEvaluation 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.
Family Atherosclerosis Counseling and Testing Project
Coronary Artery DiseaseFamily history of early atherosclerotic disease in a first-degree relative [(FDR) sibling, parent or child] is an important risk factor for coronary artery and/or vascular disease. The risk increases ~ 2 - 7 times over that of general population. Increased thickness of the intima and media of carotid arterial wall, increased rate of plaque formation is an independent predictor of cardiovascular disease. Also it is shown that increased level of calcium deposition in the arterial wall is also associated with increased level of coronary artery narrowing. We will assess the occurrence and severity of abnormalities of intima media thickness (IMT) and/or plaque formation and increased calcium deposition in the coronary arteries and their relation to the well known traditional risk factors (plasma glucose, smoking, BMI, waist circumference, blood pressure, total cholesterol, low density lipoprotein, total cholesterol/high density lipoprotein ratio) and non-traditional risk factors (C-reactive protein, Lpa, homocysteine) in FDRs of index patients with early onset of heart or vascular disease and appropriate control population. Also to determine which of the above factor can assess IMT and Ca score better. This may help to reduce the cost of investigation, and to identify the population at high risk of developing cardiovascular disease, which may help the physicians to treat early on before cardiovascular complications occur. Also this may help to reduce the cost of invasive tests, hospital admissions and medical costs overall by reducing the morbidity and mortality.
PROVIDENCE:Prevention of Restenosis With Oral Rosiglitazone and the Vision Stent in Diabetics With...
Coronary Artery DiseaseDiabetes MellitusWe hypothesize that the combination of the thin-strut MULTI-LINK (i.e. VISION(tm) and/or MINI-VISION(tm)) stent and pharmacologic therapy with the oral PPAR-gamma agonist rosiglitazone will significantly reduce restenosis after intracoronary stenting in type 2 diabetic patients. This approach would present a more effective and economical alternative to the use of drug-eluting stents to reduce stent restenosis.
Ventricular Size and Value Calcification Measures by Computed Tomography - Ancillary to MESA
Cardiovascular DiseasesHeart Diseases2 moreTo rescan 6,700 subjects in the MESA study to obtain computed tomography measures of calcification.
Effects of Exercise Training on Left Ventricular Function in Type 2 Diabetic Patients Post Coronary...
Diabetes MellitusNon-Insulin-Dependent2 moreThe purpose of this study is to investigate the changes of cardiorespiratory fitness and left ventricular function in type 2 diabetes after uncomplicated coronary artery bypass graft (CABG) surgery. We hypothesize that exercise capacity, left ventricular diastolic function, and biochemical data improves after 12-wk exercise training in patients with type 2 diabetes underwent CABG.
Serum Sex Hormone Levels and Subclinical Atherosclerosis - Ancillary to MESA
Cardiovascular DiseasesAtherosclerosis3 moreTo assess the associations of serum sex hormones with the presence and progression of subclinical atherosclerosis.
Myocardial Perfusion, Risk Factors, and Coronary Calcium
Cardiovascular DiseasesCoronary Arteriosclerosis2 moreTo determine whether an impairment of myocardial perfusion reserve is an early indicator of coronary artery disease.
Anxiety and Vagal Control of the Heart in Coronary Disease
Cardiovascular DiseasesCoronary Disease6 moreTo examine the role of reduced vagal control of heart rate in the increased risk of cardiac mortality associated with anxiety in a population with established coronary artery disease (CAD). A second objective is to determine whether the effects of anxiety are independent of the effects of depression.
