Nocturnal Oxygen Needs and Central Sleep Apnea in Patients With Chronic Heart Failure.
Chronic Heart FailureCentral Sleep ApneaThe aims of this study are to 1) determine the optimal levels of O2 flow which prevent nocturnal O2 desaturation while minimizing periods of hyperoxia during the course of nocturnal oxygen therapy (NOXT) in heart failure patients with reduced ejection fraction (HFrEF) patients with CSA/CSR; 2) document whether within-patient EO2F values change over time during NOXT, and identify factors which predict changes in EO2F; and 3) examine how well a conventional stepwise titration procedure compares to a breath by breath titration using an automated O2 titration system in terms of targeted flow rate and night time oxygenation (oxygen desaturation index, time spent at specific SpO2 targets).

NAN-101 in Patients With Class III Heart Failure
Congestive Heart FailureHeart Failure10 moreThis is a Phase 1, prospective, multi-center, open-label, sequential dose escalation study to explore the safety, feasibility, and efficacy of a single intracoronary infusion of BNP116.sc-CMV.I1c in patients with NYHA Class III heart failure. Patients with symptomatic congestive heart failure will be enrolled until up to 12 subjects have received infusions of investigational product. All patients will be followed until 12 months post treatment intervention, and then undergo long-term follow-up via semi-structured telephone questionnaires every 6 months for an additional 24 months (+/- 30 days).
DANISH-CRT - Does Electric Targeted LV Lead Positioning Improve Outcome in Patients With Heart Failure...
Heart FailureBranch Block1 moreHeart failure is a leading cause of morbidity and mortality. Cardiac resynchronization therapy (CRT) is a well-established treatment for patients with symptomatic heart failure in spite of optimised medical treatment (OMT), reduced left ventricular pump function with left ventricular ejection fraction (LVEF) ≤ 35% and prolonged activation of the ventricles (bundle branch block: BBB). CRT is established by implanting an advanced pacemaker system with three leads in the right atrium, right ventricle, and in the coronary sinus (CS) for pacing the left ventricle (LV), and often is combined with an implantable defibrillator (ICD) function. On average, CRT treatment improves longevity, quality of life and functional class, and reduces heart failure symptoms. Thus, at present, CRT is indicated for heart failure patients on OMT with BBB or chronic right ventricular (RV) pacing. It is, however, a significant problem that 30-40% of CRT patients do not benefit measurably - showing symptomatic improvement or improved cardiac pump function - from this therapy (socalled non-responders). LV lead placement is one of the major determinants of beneficial effect from CRT. Observational studies and three randomised trials with small sample sizes indicate that targeted placement of the LV lead towards a late activated segment of the LV may be associated with improved outcome. Based on this literature, some physicians already search for late activation when positioning the LV lead. However, such a strategy was never tested in a controlled trial with a sample size sufficient to investigate important clinical outcomes. Detailed mapping for a late activation may increase operating times and infection risk, result in use of more electrodes and wires, thereby increasing costs, and increase radiation exposure for patient and staff. Placement of the LV lead in late activated areas close to myocardial scar may even result in higher risk of arrhythmia and death. At present, it is completely unsettled whether targeted positioning of the LV lead to the latest electrically activated area of LV is superior to contemporary standard CRT with regard to improving prognosis for patients with heart failure and BBB. The present study aims to test whether targeting the placement of the LV lead towards the latest electrically activated segment in the coronary sinus branches improves outcome as compared with standard LV lead implant in a patient population with heart failure and CRT indication.
Electronic Alerts for Heart Failure Prevention in Diabetes
Heart FailureDiabetes Mellitus1 moreType 2 diabetes mellitus (T2DM) is an independent risk factor for heart failure (HF) and is associated with significant morbidity and mortality. Recent therapeutic advances in pharmacotherapies, such as sodium-glucose cotransporter-2 inhibitors (SGLT2i), have shown to be beneficial in preventing HF among patients with T2DM. However, despite widely available risk prediction and stratification tools and evidence-based practice guidelines, SGLT-2i medications are under-prescribed in the United States. The proposed study is a pragmatic, single-center, randomized trial to test the feasibility and effectiveness of a clinical decision support (CDS) tool to alert providers and improve HF risk stratification in patients with T2DM.
Effects of CRT Optimization as Assessed by Cardiac MR
Heart FailureSystolicCardiac resynchronization therapy (CRT), or atrial-synchronized biventricular (BiV) pacing, is an FDA-approved device therapy option for heart failure (HF) patients with reduced left ventricular ejection fraction and electrical dyssynchrony. A traditional CRT device has pacing leads implanted within the right atrium (RA), the right ventricle (RV), and within a coronary vein overlying the lateral or posterior left ventricle (LV). Within the past decade, various multi-center randomized controlled trials have reported improved quality of life, aerobic exercise capacity, LV systolic function and structure, as well as decreased hospitalization rates and mortality among patients with HF. Despite improvements in CRT technology with multipoint pacing, quadripolar leads, and adaptive pacing algorithms, approximately 30% of patients do not clinically benefit and are considered non-responders. This study looks to optimize CRT device programming in patients considered non-responders to CRTusing information obtained from standard ECG machines, and to assess acute and chronic effects of CRT optimization using cardiac magnetic resonance imaging (CMR).
