Filter by:The aim of this study is to utilize lung ultrasound to detect the development of extravascular lung water in patients undergoing clinically indicated invasive hemodynamic exercise stress testing for symptomatic shortness of breath. The study will correlate the lung ultrasound findings with cardiac hemodynamics and measurements of extravascular lung water in an effort to better understand the pathophysiology of exertional dyspnea.
This pilot study evaluates the role of massage therapy to improve self-efficacy in patients with advanced heart failure who have recently received a left-ventricular assist device. In addition to usual care, half of the volunteer patients will receive a massage at regular clinic visits and half will not receive any massage.
This is a prospective, multi-center, single-arm study enrolling adult patients who have been hospitalized for heart failure and subsequently discharged. For the duration of study participation, patients will obtain daily at-home bioimpedance measurements. Heart failure symptoms, medications, and re-hospitalizations will be tracked. Additionally, quality of life questionnaires will be administered at the beginning and end of study participation.
It is now recognized that iron deficiency in cardiovascular disease contributes to impaired clinical outcome.
This is a patient-centered comparative effectiveness feasibility pilot designed to examine an intervention to increase heart failure self-care and symptom recognition. The investigators will randomize 100 participants to receive either usual care at the time of discharge after heart failure admission or a smartphone application that enhances self-care.
Heart failure (HF) is the leading cause of death in US. It is associated with abnormal vascular function termed endothelial dysfunction. It is also associated with increased stress on the blood vessels and high levels of inflammation. Vagus nerve stimulation can help improve inflammation, vascular function and vascular stress. The investigator has recently completed a study showing that 1 hour of noninvasive vagus stimulation can improve vascular health. However, it is unknown if 4 weeks of stimulation will be beneficial in systolic heart failure. The purpose of this study is to determine if transcutaneous vagal stimulation (TVS) will lead to improvement in the function of the inner lining of participants' arteries, memory, and in the levels of certain chemical markers of arterial function in the blood. Participants will be randomized to receive either TVS or a sham stimulation and undergo 4 weeks of stimulation. Vascular function will be assessed by several non-invasive measurements, including Flow Mediate Dilation (FMD), Pulse Wave Analysis (PWA), EndoPAT, and Laser Speckle Contrast Imaging (LSCI). Participants' memory will also be measured through electronic assessments and blood will be collected and analyzed for arterial function chemical markers.
The primary purpose of this study is to evaluate the diagnostic performance of three methods for measuring right ventricular size and function including the Philips Novel RV quantification technologies (RV Heart Model volumetric analysis and Philips 2D strain) and the Upper Valley Right Ventricle Algorithm (UVRV) algorithm as compared to the gold standard of volumetric analysis via cardiac magnetic resonance imaging (CMR) in a broad patient population.
This study evaluated the safety and tolerability of LCZ696 treatment in Japanese heart failure patients (NYHA Class II-IV) with preserved ejection fraction after CLCZ696D2301 (PARAGON-HF).
The study compares the effectiveness of treatment with MitraClip to medical therapy in improving the reduction of cardiovascular morbidity and functional capacity at 24 months, in patients with moderate functional mitral regurgitation.
Cardiac Resynchronization Therapy (CRT) is an established treatment for patients with systolic heart failure and bundle branch block, improving functional capacity, quality of life and reducing morbi-mortality. However, one-third of patients are non-responders. Among factors associated with non-response, suboptimal electrical settings of the device, i.e. inadequate pacing vector selection and atrioventricular (AV) delay, is an important cause. The aim of the study is to investigate whether the optimization of CRT settings (pacing vector and AV delay) results in improved clinical and echocardiographic outcomes in a non-responder CRT population after 6 months of therapy.
