Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Heart failure develops when cardiac muscle becomes weakened and consequently is compromised in its ability to contract, relax, or both. Impaired heart function leads to reduced exercise capacity, which in turn leads to progressive muscle weakness and a vicious cycle of sedentary behavior, weight gain, and subsequent development of metabolic abnormalities and sarcopenia. Approximately 6-10% of individuals over the age of 65 suffer from heart failure, and the risk of death is 35% in the first year after diagnosis. In addition, there is a wide range of potential causes of heart failure, including the natural process of aging. Regardless of the specific underlying cause, there are common pathophysiological responses such as impaired exercise capacity, shortness of breath, fatigue and muscle strength, leading to decreased physical function. Moreover, some long-term consequences of reduced exercise tolerance and malabsorption in long-standing heart failure are loss of muscle mass and the development of cardiac cachexia, resulted in progression of sarcopenia. As protein and amino acid supplements are known to prevent loss of muscle mass or maintain muscle mass in alder individuals, in a pilot study 18 overweight/obese subjects with heart failure (all exceeded 40% body fat) were studied. Nine subjects received 12 weeks of dietary supplementation with 20 g of whey protein consumed daily, while the other nine were controls. The findings showed that supplementation with whey protein failed to improve functional performance as well as a limited stimulation of muscle protein synthesis. The lack of a demonstrable effect of whey protein is consistent with the diminished responsiveness to the stimulation of muscle protein synthesis. In contrast, a 2016 University of Arkansas for Medical Sciences (UAMS) pilot study found that the essential amino acid (EAA) mixture is better at overcoming anabolic resistance than Ensure Heart Health. In this study we will perform a randomized clinical trial of a commercially produced nutritional supplement as compared to a placebo in order to determine effects on physical function and health-related quality of life. Subjects will ingest either the EAA mixture product or placebo every day for 12 consecutive weeks. Outcomes will be determined by comparing the results of physical and functional tests from weeks -1 to 6 and 12.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
