Filter by:Prevalence of biventricular function of the heart and preoperative level of venous return is not known in non-cardiac non-morbid obese population. The aim of the study is to assess the preoperative function of the heart and status of hypovolemia on the day of surgery.
The purpose of this study is to evaluate the safety, tolerability and mechanistic effects of spironolactone, an aldosterone receptor antagonist, on sympathetic nervous system activity and right heart function and remodeling in patients with chronic right heart failure.
The purpose of this current study proposal is to identify the potential physiological adaptations arising from a combined BFR+HIIT training intervention in CHF patients. We hypothesise that the addition of BFR to HIIT will increase whole-body V̇O2peak by promoting vascular and skeletal muscle adaptations above that seen with HIIT alone. The secondary outcomes of this study are to determine if such a training intervention leads to clinical improvements in exercise intolerance symptoms and quality of life indices. Given that the majority of previous research in to both BFR and HIIT has largely involved young, healthy and relatively active participants, the final objective of this current proposal is to determine the viability, tolerability and efficacy of these training modalities in an elderly cohort of predominantly sedentary CHF patients.

This is a multicenter, prospective, single-arm study of the Optimizer Smart System with 2-leads
Half of patients with heart failure have normal heart pumping function (Heart failure with Preserved Ejection Fraction, HFpEF), most commonly characterised by breathlessness on exercise. A number of mechanisms are responsible, but frequently patients are unable to raise their heart rate on exercise. This can be treated by a 'rate-responsive pacemaker' (RRP), which detects exercise and increases the heart rate accordingly. Some beneficial effects on echocardiographic parameters have been reported with exercise programmes. However, evidence based treatment options are limited in this group and therapy mainly relies on water tablets and treatment of blood pressure. Cardiac resynchronisation therapy (CRT) is a technique using specialised 'biventricular' pacemakers that is well established in heart failure with reduced pump function. Patients who respond to this treatment have lower risk of death and hospitalisation and usually feel better. CRT is not currently used in HFpEF. The PROSPECT trial showed that some patients with relatively preserved heart function exhibited similar benefits to those with poor pump function, but this has not been formally tested. CRT aims to make the heart beat in a more synchronised way. Patients with HFpEF commonly have evidence of reduced heart synchronisation. The investigators plan to assess the feasibility of using a prospective cohort study to assess the incremental benefit of CRT over and above RRP in patients with HFpEF. 10 patients with HFpEF and insufficient heart rate will be recruited and will undergo exercise testing, heart scanning and symptom questionnaires. A biventricular pacemaker will be implanted and programmed to RRP for 12 weeks before repeating the tests. After this, the investigators will non-invasively programme the pacemaker to CRT for 12 weeks and repeat the functional tests. If incremental benefit is shown with CRT the echocardiograms will be analysed in detail to determine the mechanism of change. The study participants will be invited to continue their involvement in a study extension. This will involve non-invasively programming the pacemakers to optimise their function guided by the results of the echocardiograms in the first two phases of the study. After a further 12 weeks, the functional assessments will be repeated. If no benefit is seen with CRT after initial analysis, the participant involvement will end.
Enrolled patients implanted with Biotronik CRT-D and QP lead equipped with MultiPole pacing mode is grouped into which programmed into MultiPole pacing, or conventional bi-ventricular pacing mode. They are followed up by seven month post implantation, and predefined cardiac functional parameters are collected at each visit.
The EPIC-HF study will test the effectiveness of a patient empowerment and activation for optimization of Heart Failure with reduced Ejection Fraction (HFrEF) medication plans. Three main regional centers in the University of Colorado Health (UCHealth) system will participate in a two-arm, randomized study design. In this design, each site participates in both control and intervention, with members of the sites eligible patient population randomly enrolled in either the intervention or the control arm. All eligible patients who agree to participate in the study will complete the Baseline Survey, the Follow-Up Survey, and will have information collected from their medical record at baseline, 1 month after the first clinic appointment post-enrollment, and 1 year after enrollment. Enrollment will take place at three UCHealth locations: UCHealth University of Colorado Hospital (Metro), UCHealth Medical Center of the Rockies and UCHealth Poudre Valley Hospital (North), and UCHealth Memorial Central and Memorial North (South). Study personnel at the North and South sites will carry out enrollment and Baseline Surveys with patients for those locations; all other study procedures will be conducted by study personnel at the University of Colorado (UC) School of Medicine (SOM) (UCSOM) at UCHealth University of Colorado School of Medicine. Patients enrolled in the intervention arm will receive, by email and/or text, a link to 1) a short patient engagement video around HFrEF medications, and 2) a link to an online portable document format (PDF) of a HFrEF medication checklist. Patients in the intervention arm will receive these materials after enrollment and one week prior to their next scheduled clinic appointment. The materials will be delivered in a second communication, three days after the first, via text, as well as a third communication on the day of the clinic appointment. Patients enrolled in the control arm will not receive any materials at any point of time and will receive their usual care. For both arms, medication changes in patient medical records will be assessed before and after clinic visits to measure the effectiveness of the intervention on aim 1; surveys will be compared before and after clinic visits to determine the effectiveness of the intervention on aim 2.
The objective of this trial is to assess the effect of empagliflozin on cardiac physiology and metabolism aiming to provide a scientific explanation of the underlying mechanism by which empagliflozin improves HF related outcomes in patients with chronic heart failure
