Filter by:The purpose of this study is to determine whether levothyroxine supplementation is beneficial in patients with systolic heart failure and subclinical hypothyroidism on the functional class evaluated with a 6 minute walk test.
The present study will evaluate whether treatment with daily remote ischemic conditioning for a 28±4-day period induces beneficial effects in subjects with and without chronic ischemic heart failure in terms of improved left ventricular contractile function and exercise capacity.
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.
Ivabradine acts by inhibiting the ionic If current that modulates the pacemaker activity of sinoatrial node cells. The aim of present study is to evaluate the efficacy and safety of IvabRadine hemisulfate Sustained-release Tablets versus placebo in patients with moderate to severe chronic systolic heart failure.
This is an observational study evaluating changes in frailty and associated impairments in older heart failure patients receiving left ventricular assist device therapy.
It is a randomized prospective controlled study of transcatheter renal denervation in patients with systolic heart failure secondary to Chagas' disease. The purpose of the study is to evaluate the safety and effectiveness of renal denervation in patients with Chagas heart disease, due to reduction in renal and systemic sympathetic activity.
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.
The aim of this study is to investigate whether the use of a simple feature on the 12 lead electrocardiogram (ECG) to optimise pacemaker device programming can have clinically relevant benefit to patient management. More specifically it is to investigate whether using the R-wave in V1 of the surface ECG to guide the timings between left (LV) and right ventricular (RV) pacing improves response to Cardiac Resynchronisation Therapy.
The aim of the study is I. To assess whether an individualized exercise training program is superior as compared to usual care with respect to exercise tolerance, II. to assess whether intervention tools that aim to increase exercise adherence are superior to an individualized exercise training alone with respect to exercise tolerance and long-term effects, and III. to identify biomarkers that that may be implemented into novel intervention tools aiming to increase exercise adherence in patients with chronic heart failure.
Depression is highly prevalent among patients with heart failure (HF) and associated with lower levels of health-related quality of life and physical functioning, and higher risk of rehospitalization and mortality, and higher health costs. This Project will compare the effectiveness of a "blended" telephone-delivered collaborative care intervention for treating both HF and depression to: (1) collaborative care for HF-alone ("enhanced usual care"; eUC); and (2) doctors' "usual care" for depression (UC). If proven effective and cost-effective, the potentially more powerful, scalable, efficient "blended" care approach for treating HF and co-morbid depression could have profound implications for improving chronic illness care and stimulate development of "blended" interventions for treating other clusters of related medical conditions.
