Low-Sodium, High-Quality Diet for Heart Failure Prevention

Ann Arbor, Michigan
Tens of thousands of Veterans have heart failure with preserved ejection fraction (HFpEF), and suffer poor quality of life, frequent hospitalizations, and high death rates. Older Veterans and those with high blood pressure, obesity, and the metabolic syndrome (abnormal cholesterol and resistance to insulin's effects) are particularly at risk for HFpEF. However, it is not clear why only some Veterans in this risk group eventually develop HFpEF. Extensive information from experimental animal models and some human studies suggests that dietary patterns in vulnerable 'salt-sensitive' people could contribute to the risk for HFpEF. Reducing salt intake and increasing overall dietary quality in at-risk Veterans could prevent heart and blood vessel damage that ultimately leads to HFpEF. Reducing the development of HFpEF, which currently has no definitive treatment, is highly relevant to the VA's mission to emphasize prevention of disease and population health.

Equol for Cognitive Impairment

Pittsburgh, Pennsylvania
The ACE Trial, funded by the National Institute on Ageing/National Institutes of Health (NIH), is a multicenter clinical trial. The ACE Trial will determine if taking the dietary supplement Equol could slow the progression of stiffening of the arteries, small blood vessel disease in the brain and memory decline. Equol is a soy-based supplement that has plant estrogen-like compounds in it. Equol is a metabolite of soy isoflavone. Our studies in Japan and other studies suggest that Equol may slow mechanisms related to memory decline. No previous studies in the United States have tested the effect of Equol on these mechanisms or memory decline. Supplementation of Equol in the ACE Trial is approved by the Food and Drug Administration (FDA). Researchers at the University of Pittsburgh, Pittsburgh, Pennsylvania, Wake Forest University, Winston-Salem, North Carolina, and Emory University, Atlanta, Georgia, are recruiting participants. The ACE Trial will ask participants to complete 7 clinic visits over a two-year period. The participants are asked to take Equol tablets daily for 24 months. Clinic procedures include Pulse Wave Velocity (to measure arterial stiffness), Magnetic Resonance Imaging (MRI) of the brain and tests of awareness and thinking.

Blood Pressure Treatment for High Blood Pressure

Nashville, Tennessee
Hypertension is a common and treatable disorder that remains the leading preventable cause of heart disease. Blood pressure treatment relies mainly on upper arm blood pressure readings and ignores blood vessel physiology and underlying individual genetic information. Older Veterans with hypertension are less likely to be treated to goal blood pressure because there are conflicting recommendations for what constitutes "optimal" in older adults. The investigators have developed a novel way to non-invasively assess the components of blood vessel stiffness that is related to blood pressure (load-dependent stiffness). This project will generate new knowledge about how different blood pressure treatment goals (intensive vs standard) impact different components of arterial stiffness and if these differences can be explained through genetic analysis. Results from this project will offer the VA an updated blueprint for personalizing blood pressure care in older adults, ultimately improving cardiovascular health.

Metformin + Exercise for Metabolic Syndrome

New Brunswick, New Jersey
Arterial disease is the leading cause of morbidity/mortality in Metabolic syndrome (MetS). This occurs early as evidenced by arterial dysfunction that, in turn, raises blood pressure and glucose. Health organizations recommend exercise in an intensity based manner to promote cardiovascular adaptation and prevent disease. Metformin is a common anti-diabetes medication that reduces future type 2 diabetes and cardiovascular risk. However, the optimal exercise dose to be combined with metformin for additive effects on vascular function is unknown. Based on the investigator's preliminary work, the overall hypothesis is that metformin blunts adaptation following high intensity exercise training (HiEx) by lowering mitochondrial derived oxidative stress signaling. The investigators further hypothesize that low intensity exercise (LoEx) training combined with metformin will promote additive effects on vascular function compared to LoEx or HiEx+metformin, and maintain/improve non-exercise physical activity patterns. In this double-blind trial, obese 30-60y MetS participants will be randomized to: 1) LoEx+placebo; 2) LoEx+metformin, 3) HiEx+placebo; or 4) HiEx+metformin for 16 weeks.

Dietary Capsaicin for High Blood Pressure

Saratoga Springs, New York
The investigators long-term goal is to better understand novel interventions to promote cardiovascular health in humans. The goal of the proposed research is to investigate whether there is sex-specificity in the effects of dietary capsaicin on mechanisms regulating nitric oxide (NO) bioavailability, its effect on key markers of cardiovascular (CV) health, including BP, macro- and microvascular function, and arterial stiffness. This knowledge will provide critical insight into the effects of dietary capsaicin on CV health and will guide future trials.

Acetate Supplements for Age-Related Vascular Stiffness

Aurora, Colorado
Cardiovascular diseases are the leading cause of morbidity and mortality and contribute most to healthcare costs in the U.S. Age is the strongest cardiovascular disease risk factor, with \>90% of all deaths from cardiovascular disease occurring in adults \>50 years old. The age-associated increased risk of cardiovascular disease is due, in large part, to the development of arterial dysfunction, including endothelial dysfunction and stiffening of the large elastic arteries. Therefore, novel, effective interventions that improve arterial function will have a large public health impact by decreasing the risk of cardiovascular diseases. The short-chain fatty acid acetate is endogenously produced by the gut microbiome from fermentation of dietary soluble fiber. High-fiber diets reduce risk of cardiovascular diseases, but unfortunately, a low percentage of Americans meet guidelines for adequate dietary fiber intake and, despite nationwide efforts to improve this, trends in fiber intake have not improved over the last 20+ years. Thus, directly supplementing acetate may be a more practical and feasible intervention for effectively improving arterial function in older adults and reducing the risk of cardiovascular diseases. The investigators will conduct a study to determine the efficacy of 12 weeks of oral supplementation with acetate for improving arterial function in late middle-aged and older (50+ years) adults. They will also assess the safety and tolerability of acetate supplementation in these adults and perform innovative mechanistic analyses to determine how acetate supplementation improves arterial function. The investigators hypothesize that oral acetate supplementation will improve arterial function by decreasing oxidative stress and increasing nitric oxide bioavailability, and also hypothesize that acetate supplementation will be safe and promote high rates of adherence.

Short Walks for COPD

Kelowna, British Columbia
Chronic obstructive pulmonary disease (COPD) is a disease of the lungs that makes it hard for people to breath. Those with COPD spend considerably more time sitting and lying and less time performing physical activity than healthy individuals. Those who are the most sedentary have a greater risk of heart and blood vessel disease, which may lead to an early death. This project will investigate the effect of sitting still for 3 hours on blood vessel health in individuals with COPD. It will also investigate whether breaking up the amount of time patients sit with regular short bouts of walking (5 minutes each hour) at a comfortable pace chosen by the patient can have a positive effect on maintaining the health of their blood vessels. It is hypothesized that blood vessel health will be worse after 3 hours of sitting compared to when the sitting is broken up by short bouts of walking.

Hookah Smoke Exposure for Secondhand Smoke Effects

Los Angeles, California
In the United States, secondhand smoke is the third leading preventable cause of death. Flavored hookah (waterpipe) tobacco smoking, a highly social activity common in hookah bars, is a key source of SHS exposure. While smoke-free air laws have decreased exposure to secondhand smoke, the majority of laws do not include hookah smoking. Thus, as a social outlet for youth and young adults, hookah smoke exposure may harm non-smokers, including women of reproductive age or pregnant, hookah bar workers, children, and individuals with heart and lung disease. While more is known on the acute effects of active hookah smoking and the literature is emerging on active e-hookah vaping, little is known about the acute vascular effects of secondhand exposure to hookah smoke and aerosol. The study aims to examine the acute effects of secondhand exposure of hookah smoke and aerosol on endothelial and vascular function. Eligible volunteers will be invited to participate in a total of 3 study visits (2-3 hours each): e-hookah aerosol exposure, charcoal-heated hookah smoke exposure and smoke-free room air. Non-invasive blood pressure and blood flow measurements will be taken before and after the exposure sessions.

Frequently Asked Questions

How much do Vascular Stiffness clinical trials pay?

Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.

How do Vascular Stiffness clinical trials work?

After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across Vascular Stiffness trials 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length for Vascular Stiffness is 12 months.

How do I participate in a study as a "healthy volunteer"?

Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.

What does the "phase" of a clinical trial mean?

The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.

Do I need to be insured to participate in a Vascular Stiffness medical study?

Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.

What are the newest Vascular Stiffness clinical trials?

Most recently, we added NightWare for PTSD, Blood Pressure Treatment for High Blood Pressure and Peanuts for Prediabetes to the Power online platform.
