NCT03108456
This trial will evaluate Orbital Atherectomy compared to conventional balloon angioplasty technique for the treatment of severely calcified lesions prior to implantation of drug-eluting stents (DES).
NCT01121107
The purpose of this clinical study is to evaluate the safety and clinical effectiveness of use of a physician-directed, patient self-management system, guided by left atrial pressure measurements, for use in patients with heart failure. The system allows patients to adjust their HF medications daily based on a physician-directed prescription plan and their current HF status, similar to the manner in which diabetes patients manage their insulin therapy. The goal of the LAPTOP-HF study is to demonstrate reductions in episodes of worsening heart failure (HF) and hospitalizations in patients who are managed with the left atrial pressure (LAP) management system (treatment group) versus those who receive only the current standard of care (control group).
NCT00303498
The aim of this study was to determine whether long-term (≥ 6 months at the target dose) blockade of ETA receptors using sitaxsentan showed functional benefit in subjects with chronic Heart Failure and an Left Ventricular Ejection Fraction ≥50%.
NCT02245048
The purpose of this research study is to determine if carotid artery ultrasound scanning can provide additional information for determining cardiovascular risk in patients. Patients who agree to participate wil undergo non-invasive carotid intima-media thickness (CIMT) measurement and plaque assessment. Findings of CIMT will be compared to results of patient standard of care stress echocardiogram (SE) and of diastolic function. We hypothesize tht 1) in patients undergoing SE for inappropriate or uncertain indications, CIMT and plaque assessment will provide useful risk stratification beyond use of traditional risk factors; 2) CIMT findings will correlate with results of SE in terms of exercise capacity and 3) Exercise capacity will correlate with diastolic function.
NCT01092416
This is a prospective, single-arm, multi-center study to evaluate the safety and performance of the OAS in treating de novo, severely calcified coronary lesions in adult subjects. Study is going to enroll up to 429 subjects in up to 50 U.S. study sites. The primary safety endpoint is 30-day MACE and primary efficacy endpoint is procedural success. All subjects will be treated with the orbital atherectomy system and adjunctive stent. All subjects will be followed in clinic at 30 days. Additionally, all subjects will have an annual phone call or clinical follow up at each anniversary until study is closed.
NCT03425422
A multi-center randomized controlled clinical trial to evaluate Autonomic Regulation Therapy with the VITARIA system in patients with symptomatic heart failure and reduced ejection fraction.
NCT00709865
The purpose of the current study is to assess the safety and tolerability of intravenous tonapofylline.
NCT03354273
This is a Phase 3, prospective, open-label, international, multicentre study of Flurpiridaz (18F) Injection for PET MPI in patients referred for ICA because of suspected CAD.
NCT04169815
The purpose of the pivotal study is to collect blood specimens and clinical data from patients suspected of having Heart Failure (HF), which will be tested at a future date on Natriuretic Peptide assay(s) to validate diagnostic cutoffs and assess HF severity.
NCT01186198
This is a prospective, single-arm, open-label, multi-center, observational study to assess the acute safety and efficacy of MINI TREK RX 1.20 mm for enlarging coronary luminal diameter during percutaneous coronary intervention (PCI) procedures in subjects with ischemic heart disease due to stenotic lesions.
NCT04614467
This clinical trial will explore the efficacy and safety of GCSF-mobilized autologous CD34+ cells for the treatment of CMD in adults currently experiencing angina and with no obstructive coronary artery disease. Eligible subjects will receive a single administration of CLBS16 or placebo.
NCT00326690
The purpose of the present prospective, randomized study is to investigate the clinical effectiveness of standardized left ventricular reconstruction surgery (LVR). In order to standardize the procedure, the operation will be performed with the Blue Egg, manufactured by BioVentrix, a subsidiary of CHF Technologies, Inc.
NCT01930214
The objective of this study is to assess the current standard of care treatment outcome in none/mild, moderate and severely calcified coronary lesions using: * A composite of MACE at 30-day and one (1) year post procedure, and * Procedural and lesion success
NCT04327024
International, Multicenter, Double-Blind, Placebo and Active Control Efficacy and Safety Study to Evaluate Verinurad combined with Allopurinol in Heart Failure with Preserved Ejection Fraction
NCT03759392
The purpose of this study is to evaluate the effect of treatment with omecamtiv mecarbil compared with placebo on exercise capacity as determined by cardiopulmonary exercise testing following 20 weeks of treatment with omecamtiv mecarbil or placebo
NCT03458325
The study is to evaluate the safe admission avoidance and the overall economic impact associated with management of worsening HF using the drug-device combination product, the Furoscix Infusor, outside the hospital setting in patients initially presenting to the emergency department. The study drug, Furoscix (furosemide injection 8 mg/ml), is a furosemide solution buffered to a neutral pH containing 80 mg/10 mL for subcutaneous administration over 5 hours via the Furoscix Infusor. The study objectives are: 1. To evaluate differences in healthcare resource utilization and direct medical costs for patients treated with the Furoscix Infusor outside the hospital versus patients receiving intravenous furosemide for ≤ 72 hours in the hospital setting for 30 days post-discharge from the emergency department. 2. To evaluate the safety of Furoscix administered outside the hospital. 3. To evaluate and describe quality of life and patient satisfaction for patients who receive the Furoscix Infusor outside the hospital setting.
NCT03060577
This clinical study was designed to assess the efficacy, safety, and tolerability of long-term dosing of inclisiran and evolocumab given as subcutaneous injections in participants with high cardiovascular risk and elevated low-density lipoprotein cholesterol (LDL-C).
NCT05322616
A phase 1, randomized, double-blind, placebo-controlled single-ascending dose study to assess JK07 in adult subjects with heart failure with preserved ejection fraction.
NCT01956773
The outcome of this research will be a demonstration that family health history (FHH) risk data can be used efficiently to deliver more effective healthcare in geographically and ethnically diverse clinical care environments. Although FHH is a standard component of the medical interview its widespread adoption is hindered by three major barriers: (1) a dearth of standard collection methods; (2) the absence of health care provider access to complete FHH information; and (3) the need for clinical guidance for the interpretation and use of FHH. In addition, the time constraints of the busy provider and poor integration of FHH with paper medical records or electronic medical records (EMR) impede its widespread use. The investigators hypothesize that patient-driven and electronic collection of FHH for risk stratification will promote more informed decision-making by patients and providers, and improves adherence to risk-stratified preventive care guidelines. The study team will use an implementation sciences approach to integrate an innovative FHH system that collects FHH from patients. Intermountain Healthcare will provide the information technology expertise with EMR design to develop an innovative solution to a storage model standard for FHH data as well as a centralized standards-compliant open clinical decision support (OpenCDS) rule development architecture to analyze FHH and to generate evidence-based, individualized, disease risk, preventive care recommendations for both patients and providers.
NCT00251251
Congestive heart failure (CHF) is a common health problem that leads to frequent hospitalizations and an increased death rate. In spite of advances in drug therapy, it remains a significant public health problem. Recently, a new therapy has been developed for advanced heart failure patients with a ventricular conduction abnormality. This new therapy, called cardiac resynchronization (CRT), is a device which stimulates the atrium, the right ventricle, and the left ventricle providing synchronization of the contraction of the heart chambers. It is the addition of this therapy to an implantable cardioverter defibrillator (ICD) that will be evaluated in this study. This study will compare whether the implantation of this new therapy device, in combination with an implantable cardioverter defibrillator, will reduce total mortality and hospitalizations for CHF.
