NCT03507777
The objective of this prospective, single-blind clinical investigation is to demonstrate the superiority of an Optical Coherence Tomography (OCT)-guided stent implantation strategy as compared to an angiography-guided stent implantation strategy in achieving larger post-PCI lumen dimensions and improving clinical cardiovascular outcomes in patients with high-risk clinical characteristics and/or with high-risk angiographic lesions.
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).
NCT05202509
This study will be a placebo-controlled, double-blind, randomized, phase 3 study in participants with Atherosclerotic Cardiovascular Disease (ASCVD) who are not adequately controlled despite maximally tolerated lipid-lowering therapy.
NCT03521934
Primary Objective: To compare the effect of sotagliflozin to placebo on the total occurrences of cardiovascular (CV) death, hospitalization for heart failure (HHF), and urgent visit for heart failure (HF) in hemodynamically stable participants after admission for worsening heart failure (WHF) Secondary Objectives: To compare the effects of sotagliflozin to placebo on: * The total occurrences of HHF and urgent visit for HF * The occurrence of CV death * The occurrence of all-cause mortality * The total occurrences of CV death, HHF, urgent visit for HF, non-fatal myocardial infarction (MI), and non-fatal stroke * Change in Kansas City Cardiomyopathy Questionnaire-12(KCCQ-12) score * Change in estimated glomerular filtration rate (eGFR)
NCT02787785
The MADIT S-ICD trial was designed to evaluate if subjects with a prior myocardial infarction, diabetes mellitus and a relatively preserved ejection fraction of 36-50% will have a survival benefit from receiving a subcutaneous implantable cardioverter defibrillator (S-ICD) when compared to those receiving conventional medical therapy. The trial enrollment was stopped in 2018 due to lower than expected enrollment, all subjects enrolled at that time were followed for approximately 5 years.
NCT00985049
Hypothesis: The investigators hypothesize that genetic variants will alter gene expression in response to ischemia during cardiopulmonary bypass. To test this, the investigators will be taking small pieces of heart tissue from patients undergoing heart surgery before and after this period of ischemia. This will be compared to blood gene expression in blood cells and analyzed with the patients' genetic profile. This might allow us to assess the amount of inflammation that occurs when patients are on the heart-lung machine as well as examine the effects genes have on this critical time period.
NCT05205265
This clinical investigation is a prospective, multicenter, non-randomized, open-label, Early Feasibility Study to evaluate the safety, performance, and initial clinical efficacy of the Rivet PVS therapy in patients with symptomatic pulmonary hypertension.
NCT05312177
The study objective is to compare neurodevelopmental (ND) and behavioral outcomes between children with Down syndrome (DS) who had complete atrioventricular septal defect (CAVSD) repair and children from the same clinical sites with DS without major congenital heart disease (CHD) requiring previous or planned CHD surgery.
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.
NCT02596087
The overall goal of the IQ-MAPLE project is to improve the quality of care provided to patients with several heart, lung and blood conditions by facilitating more accurate and complete problem list documentation. In the first aim, the investigators will design and validate a series of problem inference algorithms, using rule-based techniques on structured data in the electronic health record (EHR) and natural language processing on unstructured data. Both of these techniques will yield candidate problems that the patient is likely to have, and the results will be integrated. In Aim 2, the investigators will design clinical decision support interventions in the EHRs of the four study sites to alert physicians when a candidate problem is detected that is missing from the patient's problem list - the clinician will then be able to accept the alert and add the problem, override the alert, or ignore it entirely. In Aim 3, the investigators will conduct a randomized trial and evaluate the effect of the problem list alert on three endpoints: alert acceptance, problem list addition rate and clinical quality.
NCT00458926
Non-invasive positive pressure ventilation (NIV) refers to the provision of mechanical ventilation without an artificial airway (for example, an endotracheal tube). Over the past decade, evidence from randomized control trials has accumulated to demonstrate effectiveness of the technique in avoiding intubation, reducing complications associated with intubation, shortening ICU and hospital lengths of stay, and reducing mortality rates in selected patients with acute respiratory failure. However, NIV is still underutilized at many medical centers. The purposes of this project will be to acquire information related to NIV use, to identify reasons for underutilization, to implement interventions that encourage more appropriate use of NIV, and to evaluate the effectiveness of the interventions. Reliable information on NIV use as well as analysis of reasons for underutilization will provide insight into ways of enhancing NIV use. We will determine utilization rate, technology used, patient diagnoses, duration of ventilator use and hospital stay, and success rates as recorded on case report forms (CRFs). After completing the survey, we will provide an educational program to randomly selected institutions (one-half of the total) aimed at increasing the knowledge and skill of physicians, nurses, and therapists regarding use and implementation of NIV. Data will be gathered for a second round with the same data-gathering instruments used during
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%.
NCT05310877
Heart failure (HF) represents a significant public health concern. Medication non-adherence represents a modifiable contributor to costly hospital readmissions in older adults with HF. Educational interventions improve, but do not eliminate, non-adherence. Values affirmation interventions which invite individuals to reflect on core values may encourage better engagement in health behaviors by increasing the personal relevance of targeted behaviors. Similar interventions have promoted weight loss, increased adherence and physical activity, and more frequent fruit and vegetable consumption in a variety of contexts and populations. This study seeks to test a recently developed values-affirmation intervention targeting medication adherence in older adults with HF enrolled in cardiac rehabilitation (CR). The purpose of this feasibility study is to test methodology to aid development of a subsequent randomized controlled pilot trial to examine preliminary efficacy.
NCT03093961
The objective of this pilot study is to evaluate the safety and performance of implanting the IASD® System II in Heart Failure patients with reduced ejection fraction and elevated left sided filling pressures, who remain symptomatic despite Guideline Directed Medical Therapy (GDMT).
NCT05919342
This is an international prospective, multicentre, unblinded, randomised-controlled trial. The primary aim is to assess a targeted screening strategy to detect undiagnosed heart failure in high-risk patients.
NCT01128816
Sleep Apnea (SA) is a disorder that causes pauses in breathing during sleep that expose the heart to oxygen deprivation. It is common in patients with heart failure (HF) where it is associated with increased risk of hospitalizations and death. It is not known however whether treating SA reduces these risks. This study is looking at whether a respiratory device known as Adaptive Servo Ventilation (ASV) can reduce the rate of cardiovascular hospitalizations and death in subjects with HF and SA. Study subjects will randomly receive either their regular medications OR their regular medications plus ASV. They will be followed for approximately 5 years and information relevant to their health will be collected and compared.
