Filter by:The purpose of this research is to determine the relationship between novel blood tests for heart function (including hormones and heart enzymes measured in the blood), and assess for kidney damage before and after angiography (cardiac catheterization). We hypothesize that these novel tests will enable us to predict possible complications of catheterization immediately after the procedure.
The purpose of this study is to determine whether PPAR-delta agonist (GW5015156)had favorable effect on lipoprotein metabolism.
The purpose of this study is to determine if whole and fractionated yellow pea flour, administered at USDA recommended dosages (50 g/day), improve risk factors associated with cardiovascular disease and diabetes.
Childhood obesity is a public health problem; in Mexican children a high prevalence of cardiovascular risk factors are present. Physical activity has been proposed as a strategy to reduce this risk. We conducted a pre-posttest intervention study of 214 school-aged Mexican children (4th to 6th grade), to assess the effects of two physical activity routines with different duration and intensity (40 minute aerobic routine vs. 20 minute routine) on cardiovascular risk markers. Physical activity routines were assigned randomly to two public schools in Toluca, Mexico (20 min: group 1 (n= 117), 40 min: group 2 (n=97)). The routines were implemented Monday through Friday for 12 weeks. Nutrition assessment was done before and after the intervention and included anthropometric measurements (weight, height, body mass index, waist circumference and body composition), blood pressure and biochemical analysis (triglycerides, total cholesterol LDL-cholesterol, HDL-Cholesterol, glucose and insulin). Heart rate was monitored 3 times during the intervention to evaluate the routine´s intensity.
Preliminary studies have shown that people with diabetes who undergo heart surgery may have a higher risk of developing cognitive functioning problems, including memory problems, than people without diabetes who undergo heart surgery. Among people with diabetes, however, those who control their blood sugar levels in a more intensive way during and after heart surgery may have better neurological outcomes than those who use a standard method of controlling their blood sugar levels. This study will compare the effectiveness of using a traditional method of blood sugar control versus a more intensive method of blood sugar control during and after heart surgery for improving neurological outcomes in people with diabetes.
This research study is designed to investigate the approaches to noninvasive detection and assessment of coronary vascular dysfunction in women by comparing the testing results from the invasive standard care diagnostic procedure Angiogram and from the additional noninvasive diagnostic procedure CMR Imaging. The investigators want to specifically study 375 female patients who have signs or symptoms suggestive of heart disease but don't have obstructive coronary artery disease. Two study sites (Cedars-Sinai Medical Center and University of Florida) are recruiting participants. The standard of care procedures include demographics, review of recent clinical symptoms, review of medications being taken, a physical exam, pre-angiogram blood collection, chest x-ray, ECG and heart angiogram. The research procedures for this study are the cold pressor testing, blood/urine collection, health questionnaire, the post-angiogram ECG and cardiac MRI. Patients will be asked to undergo heart angiogram testing to test for abnormalities in their heart arteries. If the heart angiogram shows that the patients do not have blockages in major heart arteries, then the patients will have coronary flow reserve measurement test (as part of the heart angiogram) to determine whether the patients have abnormally functioning of the small heart arteries. This test will be performed by infusing the three drugs: adenosine, acetylcholine and nitroglycerin. The three drugs are naturally occurring substances and have been used for routine heart angiograms. Cardiac Magnetic Resonance (CMR) imaging may help us more easily and non-invasively detect abnormalities in the inner layer of the heart muscle resulting from the abnormal function of the heart arteries. All the 375 participants will undergo baseline CMR imaging test and a subgroup of 200 participants will undergo a second CMR imaging test at their at least 1-year followup visit. Patients will be followed up using phone questionnaires at 6 weeks, 6 months for 5 years, and than annually for 20 years thereafter. Other procedures in this study include obtaining informed consent, review of demographics, physical examination, ECG, blood and urine tests, clinical symptoms, medications, questionnaires, etc. The core laboratories include Blood, Lipoprotein, Chemistry Core Lab, Reproductive Hormone Core Lab, Inflammatory Marker Core Lab, Oxidative Stress Core Lab, and Angiographic Core Lab. Additionally, GCRC at Cedars Sinai will process, store and ship samples as needed/required.
The purpose of this study is to better understand why some vein bypass grafts develop narrowing. Evidence suggests that there is a relationship between inflammatory markers in the blood and the narrowing that occurs in blood vessels. In this study, we will look at inflammatory markers in the blood and how well the vein graft functions.
This study is being conducted to learn more about the role of diet and exercise in regulating plasma triglyceride (fat) metabolism. The investigators will examine the effect of acute (24 hour) changes in energy intake and expenditure on fat metabolism the following day.
The objective of the Denver Health CVD Prevention Program is to assess the effectiveness of developing an enhanced cardiovascular disease prevention program in a community health care setting.
A concise diabetes self-management education (DSME) program on the "ABCs of Diabetes" will be placed in an urban public library to assess the feasibility of using this community setting for the delivery of health care education in an urban African American population. Impact on knowledge of, prescriptions for, and control of blood sugar (A1C), blood pressure (BP) and LDL cholesterol (LDL-C)before and after participation in the program will be assessed. We will also examine the frequency of emergency department (ED) visits and hospitalizations for uncontrolled diabetes at 6 months post-DSME intervention.
