Evaluation of Cholesterol Education for At-Risk Children
Cardiovascular DiseasesHeart Diseases2 moreTo evaluate two educational programs that promoted the role of pediatric practices in lowering LDL cholesterol levels in 4-10 year old hypercholesterolemic children through dietary modification.
Effects of Hyperglycemia on Myocardial Perfusion in Humans With and Without Type 2 Diabetes
Coronary Artery DiseaseDiabetes Mellitus Type 2The overall goal of this proposal is to determine the effects of acute hyperglycemia and its modulation by Glucagon-like Peptide-1 (GLP-1) on myocardial perfusion in type 2 diabetes (DM). This study plan utilizes myocardial contrast echocardiography (MCE) to explore a) the effects of acute hyperglycemia on myocardial perfusion and coronary flow reserve in individuals with and without DM; and b) the effects of GLP-1 on myocardial perfusion and coronary flow reserve during euglycemia and hyperglycemia in DM. The investigators will recruit individuals with and without DM matched for age, gender and degree of obesity. The investigators will measure myocardial perfusion at rest and during vasodilator stress (to ascertain coronary flow reserve) while subjects are under controlled pancreatic clamp conditions during euglycemia (glucose ~100 mg/dl) and hyperglycemia (glucose ~250 mg/dl) in the presence and absence of concomitant GLP-1 infusion. The investigators believe that the translational significance of their studies is immense, impacting upon both acute and chronic cardiovascular disease manifestations. The effect of glycemic control on cardiovascular outcomes, morbidity and mortality remains an area of active investigation, fueled by the recent conflicting results of several large clinical trials (ACCORD, United Kingdom Prospective Diabetes Study (UKPDS), ADVANCE, VADT). If the investigators find that hyperglycemia is associated with altered myocardial perfusion, the mechanistic implications in the prevention and management of acute and chronic cardiovascular diseases in DM will be groundbreaking. Furthermore, if GLP-1 augments myocardial perfusion (as it does in the peripheral vasculature), the therapeutic benefits for prevention of cardiovascular events in this predisposed population are clear.
TAXUS Libertē Post Approval Study
Coronary Artery DiseaseThe TAXUS Libertē Post-Approval Study is an FDA-mandated prospective, multi-center study designed to collect real-world safety and clinical outcomes in approximately 4,200 patients receiving one or more TAXUS Liberté Paclitaxel-Eluting Stents and prasugrel as part of a dual antiplatelet therapy (DAPT) drug regimen. This study will also contribute patient data to an FDA-requested and industry-sponsored research study that will evaluate the optimal duration of dual antiplatelet therapy (DAPT Study).
Evaluation Rehabilitation on Glycometabolic State in Non-Diabetic Coronary Artery Disease (CAD)...
Coronary Artery DiseaseThe purpose of this study is to evaluate the effects of an intensive Cardiac rehabilitation program on glucose metabolism of non-diabetic coronary artery disease patients.
Coronary Artery Disease and Its Association With Liver Steatosis Among HIV-Infected Persons
HIV InfectionsCoronary Artery Disease1 moreThe primary purpose of this study is to evaluate the association between nonalcoholic fatty liver disease (NAFLD) by computed tomography (CT) scan and coronary artery disease (CAD) measured by the calcium (CAC) score among HIV-infected persons.
Risk Markers in the Acute Coronary Syndromes
Chest PainCoronary Artery Disease2 moreThe main aim of this trial is to assess the long-term prognostic value of different types of Factor XIIa in an unselected, single center series of 871 chest pain patients admitted to the emergency unit, employing blood samples collected at admission. The second purpose of this study is to assess the incremental prognostic value of B-type natriuretic peptide (BNP) and high-sensitive C-reactive protein (hsCRP). A third purpose of this study is to evaluate the prognostic impact of the Omega-3 Index which is a measure of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) relative to other fatty acids in the erythrocyte membrane.
Conservation of Red Cell Mass , Oxygen Supply and Demand in Cardiac Surgery
Coronary Artery DiseaseFifty patients will be enrolled into the study. The purpose of the study is to investigate the relevance of Hct levels in determining need for transfusion during operations employing bypass as well as to test the hypothesis that, while HCt levels may decrease during surgery , red blood cell mass and tissue oxygenation remain fairly constant.
Premature Coronary Artery Disease in Women - Risk Factors and Prognosis
Coronary AtherosclerosisCardiovascular risk in women is systematically underestimated by both - society and physicians. Women younger than 50 years of age with acute coronary syndrome have 2x higher mortality compared with age-matched men. A number of common vascular-disease-related conditions are more frequent in women than in men. Women develop a more severe or different form of vascular disease then men. Variability of onset, relative risk, and the synergy of traditional and novel risk factors creates a challenge to physicians possibly resulting in suboptimal management and disregard in women presenting with angina symptoms. During last 10 years the rise in coronary artery disease (CAD) prevalence in younger women is observed. Emerging data suggest a unique risk profile in women (hypoestrogenemia with adverse effects of a protracted dysmetabolic state). The risk factors assessment and the risk factors profiles in women that are associated with CAD may be different than in men and thus merit reassessment. Purpose The primary objective of this study is to determine characteristics and prognosis of women with premature coronary artery disease and to evaluate the extent of atherosclerosis
Coronary Artery Disease and Sleep Apnea
Coronary Artery DiseaseThe purpose of this study is to determine the effect of sleep apnea on mortality, stroke and myocardial infarction among 408 patients with coronary artery disease referred for evaluation of coronary intervention who were examined with overnight cardio respiratory monitoring between March 1992 and June 1995.
Evaluation of the Efficacy of Rosuvastatin in Daily Practice in Untreated High Risk Patients (CHALLENGE)...
HypercholesterolemiaCoronary Heart Disease3 moreIn an observational multi-centre study (CHALLENGE), the effects were assessed of starting treatment with low doses of rosuvastatin in statin naive patients with a history of coronary heart disease (CHD), peripheral vascular disease (PVD), cerebrovascular accident (CVA), transient ischemic attack (TIA) or diabetes (DM), on low-density lipoprotein cholesterol (LDL-C) goal achievement. Also proportional changes in LDL-C, high-density lipoprotein cholesterol (HDL-C), total cholesterol (TC), triglycerides (TG) and the ratio TC/HDL-C were studied.
