Filter by:The ultimate goal of our partnership with local African-American churches is to implement an effective, multi-component intervention to increase awareness of the critical importance of healthy lifestyle in the prevention of cardiovascular disease (CVD). We will utilize the American Heart Association (AHA) prevention strategy, "Life's Simple 7" to address the major risk factors for CVD: diet, smoking, physical inactivity, hypertension, diabetes, cholesterol and obesity in order to improve overall cardiovascular health. Our main strategy consists of a community-based participatory research approach that involves focus groups to assess participant knowledge and beliefs about CVD risk factors prior to program initiation. We will also determine participant dietary and exercise practices, knowledge and perceptions related to healthy lifestyle and chronic diseases, demographic/health status information, health care utilization, biometrics (weight, blood pressure, blood tests for glucose and cholesterol, etc.) and attitudes about medical research at baseline, program completion and 6-month follow-up.
The purpose of this study is to determine whether the use of rosuvastatin in Human Immunodeficiency Virus (HIV) infected individuals lowers inflammation in blood vessels, improves blood circulation in the small arteries that provide nutrients to the heart muscle and improves neurocognitive function.
The purpose of this research is to estimate the outcomes in health and cost of the follow-up of patients with pacemakers. The initial hypothesize of this study is that remote monitoring of pacemaker will show a best relation of outcomes in costs and effectiveness than the conventional follow-up in hospital.
This study is looking at the relationship between experiences during pregnancy and cardiovascular health 2 to 3½ years later. The investigators are recruiting women from the approximately 10,000 women who were enrolled and followed over the course of their first pregnancy in another study.
Despite advances in cardiovascular care, the occurrence of heart failure (HF) is steadily increasing. The increase in HF rates poses enormous challenges, as once an individual becomes symptomatic or requires hospitalization with HF, the prognosis remains poor. Therefore, prevention of HF is essential. HF prevention is a critical issue as HF risk factors that include common medical conditions such as hypertension and diabetes are also increasing. However, not everyone with these risk factors develops HF. Using novel blood tests, the investigators propose to identify and treat subjects at higher HF risk to see if the investigators can stabilize or improve ultrasound measures known to be associated with HF risk. This study will enroll only Veterans.
Exercise training is a core component in cardiac rehabilitation. Exercise adherence is, however, low after rehabilitation and the transition from supervised to unsupervised exercise is problematic for many patients with coronary artery disease. Therefore, it is important to provide extended services to improve exercise adherence and healthy lifestyle changes. The aim of this study is to assess the effect of a time-limited intervention following out-patient cardiac rehabilitation on exercise adherence and cardiovascular risk reduction.
A human clinical consumption trial will be performed in volunteers with increased risk factors for cardiovascular disease (Metabolic Syndrome), which includes obesity and diabetes and related conditions over a period of 12 weeks with blood draws at baseline (0 weeks), 4, 8, and 12 weeks and a 24 hr urine collection on each blood draw day.
The hypothesis of this study is that the daily consumption of 75 g dried apple powder for twelve weeks will improve arterial stiffness and blood pressure by improving endothelial-mediated vasodilation and vascular sympathetic activity and favorably altering biochemical markers associated with cardiovascular risk and glycemic control compared to a macronutrient-matched control powder. 50 men and women between the ages of 45 and 65 with prediabetes or type 2 diabetes who are overweight or obese will be included in the study. After a two-week run-in phase, eligible men and women will be randomly assigned to one of two treatment groups: 1) 75 g dried apple powder; or 2) 75 g placebo powder daily for twelve weeks. After an initial telephone screening, all participants will be requested to report to the study site for their first visit. On the first visit (screening), participants will be provided with verbal and written explanation of the project. They will then be asked to sign an informed consent form, followed by measuring fasting glucose levels and a medical history questionnaire to confirm prediabetes or type 2 diabetes. Baseline assessments will be performed for medical history, medication use, dietary intake, and physical activity. Qualified participants will be scheduled for their second visit two weeks later (actual baseline data collection) and randomly assigned to their treatment group. On the second (baseline) visit between the hours of 6:00-11:00 A.M., blood pressure and vascular function will be measured followed by blood draw and urine collection. Anthropometrics will be measured. Participants will be provided with their assigned treatment and will receive standard instructions on how to fill out daily diaries for their treatment, and for food and physical activity records. Blood pressure, vascular function, blood draw, urine collection, and anthropometric, body composition, diet, and physical activity assessments will be repeated at 6- (third visit), and 12-week (final visit) intervals. All cardiovascular measurements will be performed between 6:00 to 11:00 A.M., in a quiet temperature-controlled room in the supine position after an overnight fast and 12 hours after the abstinence of caffeine and/or 24 hours after the last bout of moderate to heavy physical activity.
The purpose of this study is to understand the use of Corus CAD also known as Age/Sex/Gene Expression score (ASGES) in the clinical decision making process of patients who underwent the evaluation of chest pain or anginal equivalent symptoms. Specifically, to better understand whether the use of the assay in clinical decision making resulted in changes in noninvasive diagnostic test ordering or diagnostic yield of additional tests ordered and/or invasive angiography.
Project CONNECT ("Community-based Organizations Neighborhood Network: Enhancing Capacity Together") is a randomized controlled trial that involves 22 community-based organizations (CBOs) located in Baltimore, MD. Half of these organizations were randomly assigned to the intervention group using a constrained cluster randomization process. The remaining 11 are a part of the control intervention group. The intervention is a co-developed set of IT tools hypothesized to improve the connections among intervention CBOs, Johns Hopkins health care facilities and CBO clients.
