Filter by:Patients enrolled into the study will be randomly allocated either to Empagliflozin group or control group. In the Empagliflozin group patients will be receiving standard care + Empagliflozin 10 mg o.d., in the control group patients will be receiving standard care without sodium glucose contransporter 2 (SGLT2) inhibitors.
Heart failure (HF) with preserved (HFpEF) or reduced (HFrEF) ejection fraction is associated with poor prognosis and quality of life. While the incidence of HFrEF is declining and HF treatment is effective, HFpEF is increasing, with no established therapy. PREFERS Stockholm is an epidemiological study with the aim of improving clinical care and research in HF and to find new targets for drug treatment in HFpEF starting with a cardiac biopsy study in elective CABG patiens.
The purpose of this study is to determine whether vigorous exercise training 4-5 days/week for one year in sedentary middle aged (ages 40-64) individuals at high risk for future development of heart failure will improve cardiac and vascular compliance to a degree equivalent to life-long exercisers and the sedentary young. To date, no effective therapy for heart failure with preserved ejection fraction (HFpEF) has been found; therefore prevention is critical and discovering novel treatment strategies is essential. Exercise training if implemented in high risk patients may improve diastolic function and cardiac-vascular interactions, preventing further progression to overt heart failure.
The purpose of this study is to determine whether 1 year of supervised exercise training in obese individuals at high risk for developing HF, incorporating high intensity interval training (HIIT) two to three times per week in conjunction with daily oral administration of omega-3 poly-unsaturated fatty acids will lead to reduction in visceral adiposity, regression of myocardial triglyceride levels and improvements in cardiac diastolic and vascular function.
Objective. Atrial fibrillation (AF) recurrence after catheter ablation (CA) is a relevant clinical problem. Methods. 123 patients with paroxysmal AF will be identified and screened for participation in this randomized, prospective, double blind, controlled placebo multicenter trial. 109 patients will be randomly assigned and enrolled in the study trial. Enrolled patients will receive magnetic atrial resonance and then will be treated by CA to receive pulmonary vein isolation (PVI). In this patients cytokines, inflammatory markers, and biomarkers such as ST2 protein and B type natriuretic peptide (BNP) will be evaluated at baseline, after CA, and during follow up. These biomarkers will be correlated to clinical outcomes (AF recurrences and heart failure progression and hospitalizations), and to fibrotic atrium extension as evaluated by magnetic resonance.
The aim of our pilot study is to evaluate the feasibility, acceptance and efficacy of motivational interviewing (MI) to support elderly patients with heart failure with preserved ejection fraction (HFpEF) in maintaining or starting physical activity (PA).
The GUIDE-HF IDE clinical trial is intended to demonstrate the effectiveness of the CardioMEMS™ HF System in an expanded patient population including heart failure (HF) patients outside of the present indication, but at risk for future HF events or mortality.
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.
Patients of the University Hospital Göttingen with echocardiographic signs for diastolic heart failure and indication for right heart catheterisation will undergo additional diagnostic testing with CMR including exercise stress for detailed evaluation of diastolic dysfunction and tissue characterisation correlating the results with well-established clinical standards.
This pilot study will evaluate the efficacy and safety of CCM therapy in heart failure patients with baseline EF≥50% (HFpEF) who have New York Heart Association (NYHA) Class II or III symptoms despite appropriate medication. The terminology of the HF classification HFpEF is based on the 2016 European Society of Cardiology (ESC) Heart Failure Guidelines.
