Filter by:This is a first-in-human, randomized, double-blind, placebo-controlled, single ascending dose study in subjects with elevated plasma Lipoprotein(a) [Lp(a)]. AMG 890 will be evaluated in approximately 80 subjects to assess safety, tolerability, pharmacokinetics and pharmacodynamic effects.
Brief Summary: Current U.S. Veteran demographics reveal an aging population with significant cardiovascular dysfunction. This ultimately manifests as mobility limitation, inactivity, and a subsequent worsening of cardiovascular disease (CVD) that often leads to death. However, despite this clear negative cycle of events, there is not a single clinically accepted, and therefore routinely utilized, method of assessing vascular health. As nitric oxide (NO) is anti-atherogenic and cardioprotective, identifying an in vivo bioassay of NO bioavailability has significant worth in this arena. Fueled predominantly by the VA Merit Award prior to this renewal application, single passive leg movement (sPLM) and the subsequent blood flow increase, measured non-invasively by ultrasound Doppler in the common femoral artery, is emerging as a method by which vascular endothelial function and therefore NO bioavailability can be determined. However, although this work has yielded an initial characterization of sPLM and established this method to be a novel, valid, and a clinically relevant approach to determine vascular health, further understanding of the sPLM response with advancing age and, ultimately, its implementation and assessment in both rehabilitation and clinical arenas is still necessary. With the growing interest in personalized medicine, the development of tools, such as sPLM, that allow individualized assessments to guide the physician, the patient, and the rehabilitative team, are essential. Therefore, two specific aims are proposed that will address the Central Hypothesis that the sPLM paradigm provides a clinically meaningful assessment of endothelial function. First, cardiac rehabilitation will be assessed by sPLM in the elderly, and, coupled with studies in the young, will elucidate the predominant pathways responsible for the change in endothelial function with aging and rehabilitation. Second, the CVD diagnostic value of the sPLM assessment of endothelial function will be evaluated relative to classic measures and markers of subclinical disease in order accelerate the inclusion of endothelial dysfunction as a CVD risk factor. The proposed studies aim to catalyze the transition of the assessment of endothelial function by sPLM from research to clinical practice.
Research shows that low-dose Aspirin prevents diseases of heart and blood vessels as well as cancer of the colon and rectum and it is also associated with risk of bleeding. In this study, they want to learn how patients regard the benefits and risks of low-dose Aspirin for the prevention of these diseases. The researchers also want to learn how patients balance these risks and benefits.
The goal of the PREEMPT-HF study is to collect device and clinical event data to evaluate extended applications of the HeartLogic Heart Failure Diagnostic (HeartLogic) in a broad spectrum of heart failure patients with an implantable cardioverter defibrillator or cardiac resynchronization therapy defibrillator. There are no primary safety and/or efficacy endpoints for this study. Heart failure is a complex clinical syndrome with high morbidity, mortality, and economic burden. Chronic Heart Failure is persistent, gradually progressive, and punctuated by episodes of acute worsening leading to hospitalizations. Therefore, there remains an unmet clinical need to slow the progression of Heart Failure and prevent hospitalizations. HeartLogic, available in Boston Scientific cardiac resynchronization therapy devices and defibrillators, combines novel sensor parameters such as heart sounds and respiration with other measurements like thoracic impedance, heart rate, and activity into a HeartLogic Index for the early detection of worsening Heart Failure. However, there is limited data on the association of HeartLogic with the risk of Hear Failure readmissions and tachyarrhythmias, or for phenotyping the broad spectrum of Heart Failure patients.
Cardiovascular disease remains the leading cause of morbidity and mortality in the U.S. and is a major cause of disability in Veterans. Most of these deaths are due to coronary artery disease (CAD). The most common treatment for CAD is revascularization, an invasive procedure which usually involves placing a stent inside an artery that is diseased. However, exercise training is often overlooked because clinicians tend to focus on repairing the coronary circulation and the potential need for revascularization. Studies have shown that exercise training can be effective for patients with CAD and that it saves costs. In this study, invasive revascularization will be compared to a structured program of exercise training over one year. Comparisons will be made between groups for symptoms, coronary artery size and function using PET/CTA, and health care cost utilization.
The purpose is to evaluate the effect of single therapeutic (400 mg) and supratherapeutic (1200 mg) doses of BIA 5-1058 on the time-matched change from baseline in placebo-adjusted interval corrected (QT) for heart rate (HR)
The purpose of this study is to explore how working with a partner can influence participation in a church wellness program. There are many different types of church wellness programs. Church members are more likely to participate and achieve goals in these programs when they have peer support. The researcher would like to know what African American men and women think about working with a support partner. This information will help researchers design better church wellness programs. The participants are being asked to take part in this research because the investigators believe that it is helpful to share feelings and thoughts about experiences working with a partner to achieve health goals. This knowledge will be used to create church wellness programs that will help African American men and women prevent disease and live healthier lives.
The investigators will conduct an epidemiological analysis of data from the Women's Health Initiative to investigate the prospective association between chocolate intake and the risk of heart disease and stroke.
The principal objective is analyzed whether a selective intervention no pharmacological (use of ABPM +/- prescription of physical exercise) for cardiovascular risk factors in patients with high cardiovascular risk in primary prevention is associated with a decrease in cardiovascular risk measured using the risk Score tables for countries with a low risk. It will be independently analized the effectiveness of systematic use of ABPM and the prescription of physical exercise.
The study is a two-arm, parallel, randomized clinical trial. The purpose of the study is to evaluate the effectiveness of automated mobile phone text message-based intervention for secondary prevention after acute coronary syndrome hospitalization. Text messages will include information about lifestyle modifications, medication adherence and cardiovascular risk factor control. The participants will be randomized into intervention and control groups in a 1:1 ratio. The intervention group will receive 4 pre-designed and semi-personalized text messages per week in addition to usual care for 6 months, while the control group will receive usual care.
