Autologous Atrial Appendage Derived Cells in the Treatment of Heart Failure
Heart FailureThis study aims to evaluate the safety and clinical feasibility of epicardially delivered autologous atrial appendage micrografts in the treatment of heart failure. The micrografts consisting atrial-derived cells and their extracellular matrix, are placed on an infarction scar during CABG surgery.

Exercise Training Following Cardiac Resynchronization Therapy in Patients With Chronic Heart Failure...
Cardiac Resynchronization TherapyChronic Heart FailureCardiac resynchronization therapy(CRT) is recommended to reduce mortality and morbidity in chronic heart failure(CHF) patients New York Heart Association(NYHA) class III-IV who are symptomatic despite optimal medical therapy, with a reduced left ventricular(LV) ejection fraction(LVEF) and prolonged complex QRS. CRT improves the prognosis however, despite the improvement, all major trials have demonstrated that one third of the patients are non-responders to CRT. Three months after the CRT implant, the responders have a significant increase in endothelial function(EntF), a decrease in the LV end-systolic volume, and increase in LVEF, 6 minute walk test(6MWT), improvements in NYHA class and quality of life. It is currently unknown if adding an exercise training(ExT) program following CRT provides better clinical outcomes than CRT alone. Prior studies on CRT and ExT have been preliminary in nature, but suggest small improvements in functional capacity(FC). The correction of endothelial dysfunction is associated with a significant improvement in exercise capacity evidenced by a 26%increase in peak oxygen uptake. These findings are important because CHF patients with the greatest sympathetic activation and the most reduced EntF have the poorest prognosis. Our experience with coronary artery disease patients, and most recently data in patients with CHF show that an ExT program that combines aerobic exercise(AE) and resistance exercise training are more effective than an AE program alone, and the aerobic interval training showed better improvements than continuous endurance training. It is unknown how CHF with more severe functional limitations responds to ExT and, more important, the explanation of the physiological mechanism that can explain the improvements as a consequence of ExT. This lack of scientific information is urgent since this is the group of patients that normally is targeted for CRT. The investigators propose to use a stratified randomized longitudinal study to determine the additional effects of a 6 month ExT in addition to CRT in NYHA stage III-IV HF patients. The aims of the study are:1-to determine whether a long-term ExT program follow the CRT provides better clinical outcomes than CRT alone and 2-To identify the mechanisms of the hypothesize improvement. The results of this project will represent an important contribution by understanding the role of ExT after CRT NYHA stage III-IV heart failure(HF) patients, an understudied population with poor clinical outcome. Understanding the potential mechanisms associated with clinical improvement and outcome is essential for the rehabilitative process to develop new innovative therapies in this high risk population. The investigators will use state-of-art methods including an integrated assessment autonomic nervous system(ANS) and arterial function using 123I-MIBG scintigraphy.

Remote Supervision to Decrease Hospitalization Rate
Heart FailurePurpose: Home monitoring (HM) services supplied by different manufacturers (St Jude Medical, Biotronik, Medtronic) enables trained medical staff (doctors, electrophysiology nurses and technicians) to safely follow-up patients with implanted ICD/CRT-D remotely, with omitting unnecessary visits in outpatient clinic, shortening time to medical intervention and therefore help to decrease hospitalization rate among those patients. The RESULT study primary endpoint of the trial will be a composite of all-cause death or hospitalization due to cardiovascular reasons. The primary technical endpoint is to construct and evaluate a unified and integrated platform for data collected from RM devices manufactured by different companies: Carelink™ (Medtronic®, Minneapolis, MN, USA), Merlin™ (Saint Jude Medical®, St. Paul, MN, USA) and Home Monitoring™ (Biotronik®, Berlin, Germany).

Safety and Effectiveness of SGLT-2 Inhibitors in Patients With Heart Failure and Diabetes
Heart FailureDiabetesPatients with diabetes are at increased risk of developing heart failure (HF) which can lead to increased shortness of breath, reduced ability to exercise and in some cases premature death as the heart becomes less efficient at pumping blood around the body. However the treatment options for such patients remain limited. This study will test the safety and benefits of using a new class of drug, the SGLT2 Inhibitor (Dapagliflozin), in treating HF and diabetes. Participants will have a Magnetic Resonance Imaging (MRI) scan of the heart, to measure the efficiency and the extent of thickening of the heart muscle before they start on treatment of dapagliflozin, or placebo for one year. They will also do exercise testing on an exercise bike (if capable) and a walking test plus fill in some questionnaires on how their heart failure affects their quality of life. Participants will then continue as normal with currently prescribed medication for their diabetes and heart failure. After a year the tests will be repeated to determine if patients receiving Dapagliflozin benefited more than those who weren't on the drug. This study is funded by the European Foundation for the Study of Diabetes (EFSD)

Medication Adherence Telemonitoring to Reduce Heart Failure Readmissions
Heart FailureThe overall purpose of this project is to determine the feasibility of conducting a large scale randomized clinical trial that compares remote monitoring of adherence to loop diuretics using a wireless electronic pillcap with usual care among recently hospitalized heart failure patients. The long-term goal of this program of research is to determine the effect of the adherence telemonitoring intervention on medication adherence and hospital readmissions among recently hospitalized heart failure patients.
