Cardiovascular Diseases Clinical Trials

The main purpose of research is to examine and understanding the development of hypertension in obese adults with insulin resistance. Findings from our studies will identify unique mechanisms that can be targeted to limit increases in vascular dysfunction and reduce the excessively high prevalence of hypertension and risk for cardiovascular disease (CVD). This study is testing the health of the blood vessels and the activity of the nerves that control the blood vessels in adults with insulin resistance. The extent to which ascorbic acid (Vitamin C) improves the function of the blood vessels will be determined. The primary outcome is blood pressure, which is the result of blood vessel health and activity of the nerves, and the reduction in blood pressure that is observed with ascorbic acid. Read Less

The objective of this research project is to conduct a single-site pilot trial to assess the feasibility and effect of low-dose aspirin to augment vascular recovery in the immediate postpartum period after preeclampsia through two specific aims: 1) to pilot test the feasibility of conducting a randomized controlled trial of postpartum low dose aspirin vs. placebo, and 2) to assess the effect of postpartum aspirin on endothelial function and blood pressure. Our central hypothesis is that postpartum administration of low-dose aspirin following preeclampsia will be feasible, improve endothelial function, and lower BP at 6 months postpartum. Subjects will undergo 3 study visits involving BP measurements, blood draws, questionnaires, and/or microiontophoresis. Up to 60 adult subjects will be enrolled at Magee-Women's Hospital. Read Less

The goal of this clinical trial is to examine the effect of the ketogenic diet over four weeks on blood lipid levels and risk factors for heart disease in adults with a healthy BMI compared to adults with a body mass index (BMI) in the range for obesity. The main questions it aims to answer are: * Does the ketogenic diet cause larger increases in "bad cholesterol" (low density lipoprotein-cholesterol) in adults with a healthy BMI compared to adults with BMI in the range for obesity? * Does the ketogenic diet cause larger decreases in vascular health in adults with a healthy BMI compared to adults with BMI in the range for obesity? Participants will: * Consume all of the study food provided and avoid intake of non-study foods during the 28-day diet period * Visit the metabolic kitchen daily (Monday-Friday) to pick up meals * Attend 5 fasting visits at the Clinical Research Center for testing Read Less

Emergency Medicine Cardiovascular Risk Assessment for Lipid Disorders (EMERALD) is a protocolized intervention based on American College of Cardiology/American Heart Association and US Preventive Services Task Force guidelines designed to initiate preventive cardiovascular care for emergency department patients being evaluated for acute coronary syndrome. The overarching goals of this proposal are to (1) determine the efficacy of EMERALD at lowering low-density lipoprotein cholesterol (LDL-C) and non high-density lipoprotein cholesterol (non-HDL-C) among at-risk Emergency Department (ED) patients who are not already receiving guideline-directed outpatient preventive care and (2) inform our understanding of patient adherence and determinants of implementation for ED-based cardiovascular disease prevention strategies.

Despite many advances in our understanding of the natural history and progression of chronic kidney disease (CKD) and cardio vascular disease (CVD) in the parent CRIC study over the past 15 years, important questions about key risk factors for these diseases remain unanswered in the AI population. To address this burden of CKD in AI communities Investigators formed a consortium of investigators with extensive experience in conducting research of chronic diseases including diabetes, cardiovascular and kidney disease in AIs of Southwestern US. The proposed CRIC ancillary cohort study of 500 AIs (AI-CRIC) will rapidly improve our understanding of both potential risk factors for CKD progression, as well as the scope of this disease among AIs. This study leverages the current CRIC study and incorporates the planned activities of the next phase of the study - "CRIC 2018" - by implementing contemporary CRIC protocols for kidney and cardiovascular measurement and outcomes.

Despite the benefits of physical activity (PA) to prevent cardiovascular disease and other chronic diseases, few adult Latinas meet PA guidelines. Given the central role of churches within the Latino community and their commitment to the well-being of their members, they are ideal settings for health promotion. Evidence-based interventions (EBIs) for increasing PA and reducing obesity exist, but few PA interventions go to scale. Investigators propose to enhance Faith in Action with three organization-level strategies designed to increase program fit and effectiveness: 1) training church leaders in health promotion; 2) tailoring messaging to enhance fit between Faith in Action and each unique church environment; and 3) empowering community health workers (promotoras) to advocate for organizational change. Given the need to improve strategies to sustain health programs in community settings, investigators will test the influence of two additional sustainment strategies: 1) strengthening community collaborations and 2) providing technical support. Thirty-two churches will be randomly assigned to a Standard EBI group (Faith in Action as originally implemented), an Enhanced group (Standard intervention + organizational-level implementation strategies), or an Enhanced + Sustainment group (Enhanced implementation group + sustainment strategies). Investigators will test the proposed implementation strategies on organization-level change and individual behavior in diverse churches for a 12-month intervention and 6-month follow-up period. The proposed study aims to: 1) Test the short and long-term impacts of organization-level implementation strategies in 2 Enhanced conditions on organizational outcomes compared to the Standard EBI condition and 2) Examine individual behavior change among Latinas (N=677) in churches in the 2 Enhanced conditions compared to the Standard EBI condition. The study's primary hypothesis is that Latina's receiving the Enhanced interventions will increase their PA levels significantly more than those receiving the Standard Faith in Action intervention, and the improvements in PA will be sustained. If successful, findings from the current study will provide evidence of organizational-level strategies for uptake, sustainment, and implementation strategies for scale-up of PA interventions to increase PA and reduce chronic disease in churches across the US.

Cardiovascular disease (CVD) disproportionately affects racial/ethnic minorities and underserved populations in Philadelphia. This study aims to evaluate the effectiveness of an enhanced community health worker (CHW) program that combines the evidence-based DECIDE self-management intervention with structured CHW consultations to improve CVD self-management skills and address social needs. Using a Type 1 Hybrid Effectiveness-Implementation Design, we will recruit 500 Philadelphia residents aged 35-75 with CVD risk factors and unmet social needs. Participants will be offered the DECIDE+ intervention (9 bi-weekly group sessions plus alternating CHW consultations) or continue with standard CHW services. The primary outcome is CVD self-management skills measured by the Self-care of Chronic Illness Inventory Maintenance scale. Secondary outcomes include health behaviors and resolution of social needs. Implementation outcomes will assess CHW experiences, community advisory council impact, and factors influencing participation. Propensity score methods will be used to compare changes in outcomes between DECIDE+ participants and those receiving standard CHW services. Mediation analyses will examine pathways through problem-solving skills, self-efficacy, and social needs resolution. Mixed methods will evaluate implementation outcomes. This study will provide evidence on the effectiveness of integrating an evidence-based self-management program with CHW services to address both clinical and social needs. This study has the potential to generate important and impactful findings that can advance health equity and the science of effective community health worker programs. By rigorously evaluating the real-world implementation of a city-wide CHW-delivered chronic disease self-management program that also addresses collaborative approaches and support to addressing social needs, our findings can provide a roadmap for other communities looking to implement evidence-based interventions to reduce health disparities. Demonstrating improved CVD self-management behaviors and reduced social needs among Philadelphia residents receiving the DECIDE+ intervention would provide compelling evidence for the synergistic benefit of these services, and to sustain and scale up this model. OBJECTIVES: We propose both effectiveness and implementation questions to guide our work: Effectiveness of CHW Engagement: 1. Is the DECIDE intervention with CHW consultations (DECIDE+) effective in improving CVD self-management skills compared to the standard and limited CHW engagement? 1. Do DECIDE+ sessions improve CVD self-management skills by strengthening problem solving and self-efficacy? 2. Does participation in CHW consultations improve CVD self-management skills by meeting social needs? Implementation Questions: 2. What key sociodemographic and psychosocial factors influence client participation in the study? 3. How do CHWs perceive the impact of facilitator training on their a.) knowledge, attitudes and practices in supporting clients b.) personal health management, and c.) job satisfaction? 4. How does the CAC facilitate resource mobilization to enhance access to services that address social needs in Philadelphia's communities? Read Less
