Filter by:In this study, the effects of core stabilization and computerized wobble board exercise training programs on postural balance and functional exercise capacity in patients over 60 years of age with heart failure will be investigated.
Cardiac resynchronization therapy reduces mortality in patients with systolic heart failure and left bundle branch block. Reduced biventricular pacing can lead to therapy failure. Most effective mortality reduction was seen with a BiV pacing above 98%. Reduced BiV pacing is a common phenomenon with potential impact on CRT-response and pts' prognosis. Frequent ventricular ectopy may be associated with attenuated benefit from CRT. The investigators sought to systematically assess the effect of ventricular arrhythmia treatment on BiV pacing.
Researchers are observing the values of proEnkephalin (PENK) via a blood draw in hospitalized patients that are volume overloaded requiring diuresis. If changes in PENK are found, physicians may predict values of change in kidney function during treatment.
This is a Phase 1b randomized, double-blinded, single-center safety and pharmacodynamics study of sequential cohort, dose-escalating, repeat-dosing of dapansutrile or placebo (4:1 ratio) in subjects with stable systolic heart failure (HF) with LVEF≤40% symptomatic for NYHA functional classification II-III who show signs of systemic inflammation (high sensitivity plasma C reactive protein [hsCRP] > 2 mg/L). A total of 30 subjects will be enrolled in 3 sequential cohorts by randomized allocation (8 active and 2 placebo within each cohort). Progression to cohort 2 with dose escalation will occur following the Day 28 visit of the last subject in the first cohort. Progression to cohort 3 with dose escalation will occur following the Day 8 visit of the last subject in the second cohort. Subjects will be screened and evaluated twice for eligibility: 1) at the time of Screening (up to 28 days prior to enrollment); and 2) at the Baseline visit, prior to randomization. Following enrollment, Baseline assessments will be conducted and the first dose of investigational product (either dapansutrile capsules or placebo capsules) will be administered at the clinical site upon completion of all assessment and collection of baseline parameters. Subjects will then self-administer investigational product once, twice or four times daily, depending on cohort, for up to fourteen (14) consecutive days beginning at the Baseline visit and continuing through the planned Day 14 visit. Subjects will return to the study clinic on Days 4, 8, 14 and 28 for follow-up visits. Additionally, subjects will be contacted for telephone follow-up on Day 42.
The purpose of this study is to determine whether using a mobile app increases adherence to a heart healthy prescription after discharge from a cardiac rehab program.
Cardiac resynchronization therapy (CRT) is a demonstrably effective device intervention for patients with heart failure with reduced ejection fraction and specific indication. However, many patients with heart failure (HF) are unable to maintain sinus rhythm and approximately 30-36% of CRT patients are in atrial fibrillation (AF).
Controlled exercise training is a valuable therapeutic addition to pharmacological treatment in most patients with chronic heart failure, reducing long-term mortality, preventing cardiac remodeling and improving functional capacity. Despite the mechanism underlying its benefits might be multifactorial, a sustained improvement in autonomic balance is usually attributed as a major effect. Nevertheless, not all eligible subjects show the same response to exercise, probably due to several differences in the subpopulations enrolled. The investigators hypothesize that some Heart Rate Variability indexes could be valid tools to optimize the selection and follow-up of chronic heart failure patients to training
Nitrate-rich beetroot juice supplementation has demonstrated reduced oxygen consumption and submaximal exercise performance in healthy adults. Investigation for similar effects in patients with heart failure has not previously been conducted. This was a randomized, double-blind, placebo controlled trial. Following ingestion of the active agent or placebo, subjects with systolic heart failure underwent submaximal steady state exercise with gas exchange analysis followed thirty minutes later by a six minute walk test. Second testing sessions were performed ten days. There were no significant differences in the treatment and placebo arms in average oxygen consumption or six minute walk distance. In conclusion, in patients with heart failure who have ingested a single dose of nitrate-rich beetroot juice concentrate, there is no significant difference with regard to oxygen consumption during submaximal steady state exercise or six minute walk testing distance. Further study is warranted to determine the true efficacy of nitrate consumption in this population with adjustments in acute or chronic dosing, exercise duration, or intensity.
This is an observational study evaluating changes in frailty and associated impairments in older heart failure patients receiving left ventricular assist device therapy.
This study will randomize participants with a diagnosis of congestive heart failure and at least one risk factor for hospitalization to either a tablet computer and web based disease management program or a telephone based disease management program. Both interventions are home based with heart failure education and symptom monitoring provided by nurse managers. The nurse managers are in close communication with both the participants and the participants' physicians . The components of the disease management program have been developed at Tufts Medical Center and the New England Quality Care Alliance with studies showing improved clinical outcomes, including reduced hospitalizations. The goal of this study is to transition this successful home monitoring and disease management program to a tablet computer and web-based implementation to both improve clinical outcomes (reducing hospitalizations and improving self-perceived health status) and improve provider-patient satisfaction. We hypothesize that the tablet computer based disease management will decrease heart failure hospitalizations.
