The objective of the study is to test whether 12 weeks of structured supervised exercise training on top of usual care improves functional capacity in patients with end-stage heart failure with continuous flow left ventricular assist device (LVAD).
The purpose of this study is to quantitate electrical dyssynchrony in heart failure (HF) patients with a narrow QRS complexes (≤ 130 ms) using the ECG Belt. This is a pilot study that is designed to provide data that can be used in designing and implementing a prospective study of cardiac resynchronization therapy (CRT) in narrow QRS patients selected and optimized using the ECG Belt.
The investigators are interested in determining the best surgical technique to correct functional mitral regurgitation, as there is currently not one technique that is established to work better than the other. The technique used in current clinical practice is undersizing mitral annuloplasty (UMA), in which a prosthetic ring is implanted onto the mitral valve to correct the leakage. Though widely adopted, durability of the repair is less, as 58% of the patients present with recurrent FMR within 2 years. There are no specific algorithms to predict who might have UMA failure, but research indicates that some geometric indices might be strong predictors. The investigators are interested in testing the hypothesis that, elevated lateral inter-papillary muscle separation (IPMS) is a predictor of post-UMA recurrence of FMR at 12 months. In the first part of this study, the study team will measure lateral IPMS before surgery, and relate to post-surgery FMR severity at discharge/30 days, 6 months and 12 months. A relatively newer technique is papillary muscle approximation (PMA), in which a suture draws together the two muscles that connect the mitral valve to the heart muscle prior to performing UMA. This reduces the lateral inter-papillary muscle separation (IPMS) and is expected to improve the durability of UMA. In the second part of this study, the investigators will perform PMA and UMA together and determine if FMR severity is reduced at discharge/30 days, 6 months and 12 months.
The registry is primarily designed to assess outcome, efficacy and residual safety aspects of CRT based on long-term data from an unselected, real-life clinical set-up. Moreover, the observation of the patient status should help to find possible predictors for HF events and to identify areas of improvement for CRT and for CRT device settings.
Failing heart negative remodeling alterations might provide electrical heterogeneity and cardiac remodeling, thus potentially contributing to the occurrence of ventricular arrhythmia and subsequent sudden cardiac death (SCD). In this study we have prospectively investigated whether serum markers of heart failure (ultra sensitive Troponin , B type Natriuretic Peptide (BNP), C reactive protein (CRP), and ST protein) could be used as predictors for the occurrence of malignant ventricular arrhythmias in patients who had received an Implantable Cardioverter Defibrillator (ICD) for primary prevention.
To determine the safety and efficacy of an intracoronary injection of adenovirus 5 encoding human adenylyl cyclase 6 (RT-100) in patients with heart failure with reduced left ventricular ejection fraction (HFrEF) in a Phase 3 clinical trial.
The CHILISALT Study aimed to explore the effect of angiotensin-neprilysin inhibition on intrathoracic impedance and -derived fluid index in HFrEF patients who had a device for cardiac resynchronization therapy and/or an implantable cardioverter-deﬁbrillator (ICD; Medtronic Inc., Minneapolis, MN) allowing continuous measurement of intrathoracic impedance.
This study will evaluate the usefulness of the subcutaneous administration of a new Lasix formulation. 20 patients will be evaluated in the first phase (pilot phase) and depending on the results, an additional 40 patients will be enrolled (Evaluation Phase). Patients with mild to moderate evidence of fluid overload who present to the cardiology service at St Elizabeth's Medical Center, Brighton, Massachusetts (SEMC) will be included in the study. Patients who qualify for thus study will be sent home with the sc2Wear™ Furosemide Infusor therapy for three days. This is a pump that patients place on their abdomen and it then delivers furosemide to the skin. Participants will be visited at home by a visiting nurse who will give them further teaching on the sc2Wear™ Furosemide Infusor. The visiting nurse will also be responsible for obtaining history (symptoms), physical examination (including inspecting the skin for adverse reactions related to the pump), and laboratory draws, supplementation of electrolytes as needed. Patients will be evaluated by the cardiology service of SEMC within 24 hours of the last dose of the sc2Wear™ Furosemide Infusor. If a patient is found to have satisfactorily responded but requires more therapy, an additional 4 days may be prescribed for total of seven consecutive treatments. If additional units are prescribed, patients will be evaluated by the cardiology service of SEMC within 24 hours of the last dose of the sc2Wear™ Furosemide infusion. Also an additionally, up to three-sc2Wear furosemide at home treatments may be used as authorized by the treating physician in case the patient experiences worsening heart failure within 30-days of enrollment (Rescue Treatment). Participants will be seen in clinic for follow up at 30±3 days after the start of the study for a post treatment.
Heart failure is the most rapidly rising cardiovascular disease and has come to be recognized as a growing epidemic. Digital health interventions are the most recent iteration of an effort to promote individualized outpatient care through positive behaviour change theory. The UHN team has developed a highly automated and user-centered smartphone-based system, Medly, which allows for the telemonitoring of patients diagnosed with heart failure. The purpose of this study will be two-fold: 1) to determine if the introduction of Medly within two weeks of discharge will improve self-care management, quality of life, and clinical status, 2) to assess whether Medly will lead to a potential reduction in 30 day readmission rates amongst HF patients in the Toronto Central Local Health Integration Network (TC LHIN), without increasing the average length of stay or visits to the emergency department. These parameters will be measured as secondary outcomes.
The purpose of this study is to evaluate the effects of BMS-986231 on systolic and diastolic parameters in patients with heart failure and low ejection fraction.
