NCT03016754
This study is designed as a multi-center prospective observational study of newly diagnosed Heart Failure (HF) patients to test the hypothesis that additional Ejection Fraction (EF) recovery occurs between 90 and 180 days as Guideline Directed Medical Therapy (GDMT) is achieved. Although the study doesn't start until day 90, all eligible, consenting patients will be entered into a registry at the start of wearable cardioverter defibrillator (WCD) use. The pre-study registry will allow us to collect early (90 day) outcomes and data in those patients who are likely to be eligible for the study at day 90, or are eligible, but refuse the study at day 90.
NCT04089059
This is a prospective, open- label, single arm, multicenter clinical trial to evaluate the safety and effectiveness of the Cordella PA Sensor System in NYHA Class III Heart Failure Patients compared to a Performance Goal (PG).
NCT04356027
The purpose of the FUSION study is to validate the diagnostic performance of Virtual Flow Reserve (VFR) by comparing it against a reference standard, fractional flow reserve (FFR).
NCT04799899
The aim of this study is to establish, in a pilot RCT (approx. N=50 participants) with a time- and attention-matched health enhancement control, (a) the feasibility of the recruitment procedures (screening, eligibility, enrollment rates), and feasibility and acceptability of the (b) MBCT and control interventions (adherence, retention, fidelity, satisfaction, group videoconferencing delivery) and (c) data collection procedures by group (adherence, satisfaction). Hypothesis 1a: Recruitment will be feasible as evidenced by screening, eligibility, and enrollment rates; (1b) the MBCT and control interventions and (1c) data collection procedures in both groups will be feasible and acceptable.
NCT04451044
Multi-center, prospective, randomized controlled study comparing PCI guided by angiography versus iFR Co-Registration using commercially available Philips pressure guidewires and the SyncVision co-registration system, employing an adaptive design study for interim sample size re-estimation.
NCT03476187
Subjects meeting the inclusion/exclusion criteria will wear the µCor for at least 90 days. During the study, clinic follow up will occur every 30 days. For all subjects, each scheduled clinic visit will include assessment of cardiac symptoms and any relevant clinically actionable events. The subject will be given a daily diary to track symptoms, unplanned hospital visits, medication changes, and all other heart failure related clinical events. Weekly phone calls to the subject will be given throughout the duration of the study to remind the patient to use the subject diary and to collect and record heart failure related clinical events. Subjects will be contacted six months and one year from initial enrollment to assess the vital status of the subject, any heart failure related clinical events since the end of µCor wear, and any health care utilization since the end of µCor wear.
NCT03541603
Phase 2 study to evaluate the efficacy and safety of intermittent levosimendan compared with placebo in hemodynamic improvement with exercise in PH-HFpEF subjects
NCT03962855
This study evaluates whether addition of the thromboxane receptor antagonist to chronic aspirin therapy improves endothelial function and reduces non-platelet thromboxane generation in patients with established cardiovascular disease. Half of participants will receive ifetroban and the other half will receive matching placebo for the 4 week study period.
NCT00826280
Observe whether the administration of caffeine prior to regadenoson will affect the interpretation of test results in subjects with coronary artery disease (CAD) undergoing SPECT MPI
NCT01426425
ICY-AVNRT (Intracardiac CrYoablation for AtrioVentricular Nodal Reentrant Tachycardia) is a prospective multi-center, nonrandomized, single arm, controlled, unblinded, investigational clinical study. The purpose of this clinical study is to demonstrate the safety and effectiveness of the Freezor® Xtra Cardiac CryoAblation Catheter for the cryoablation of the conducting tissues of the heart in the treatment of patients with atrioventricular nodal reentrant tachycardia (AVNRT) using an endocardial approach.
NCT04096040
To assess investigator engagement of μCor system data in the context of heart failure management. The μCor system includes a sensor and wearable patch for fluid management.
NCT05118893
This is an extended follow up study of the original RAFT-AF Study. The RAFT-AF study was a multi-centre randomized controlled trial with a prospective randomized open blinded endpoint trial (PROBE) design. Patients were randomized to either catheter ablation-based rhythm control of AF as compared to rate control of AF
NCT04610892
A Phase IIB Parallel group Study to Evaluate the Efficacy and Safety of MEDI6570 in Participants with a Prior Myocardial Infarction.
NCT06097663
This Phase 2a clinical trial will evaluate the effectiveness, safety, and tolerability of increasing dose strengths of an oral daily medication, DFV890, administered for 12 weeks, or a single s.c. dose of MAS825, to reduce key markers of inflammation related to CVD risk, such as IL-6 and IL-18, in approximately 28 people with known coronary heart disease and TET2 or DNMT3A CHIP (VAF ≥2%).
NCT04838353
Patients with heart failure and preserved left ventricular ejection fraction (HFpEF, EF ≥ 50%) or mid-range left ventricular ejection fraction (HFmrEF, 40% \< EF \< 50%) with mild to moderate functional limitation will be evaluated for treatment via creation of a no-implant interatrial shunt using clinical, echocardiographic, and invasive hemodynamic data
NCT05835024
Acorai is developing a non-invasive monitoring system for the estimation of intracardiac hemodynamic parameters in patients with suspected or confirmed heart failure, and/or pulmonary hypertension, who require hemodynamic assessment. The device will be intended as a companion test or clinical decision support tool to be used and interpreted by qualified healthcare professionals to aid standard-of-care clinical assessment in identifying hemodynamic congestion and supporting personalized treatment of heart failure and pulmonary congestion. This study is part of the development of a non-invasive monitoring system for the estimation of intracardiac hemodynamic parameters. It will be conducted to collect the data needed to train the machine learning models retrospectively.
NCT05386173
In one of the most severe congenital heart defects, hypoplastic left heart syndrome (HLHS), the left ventricle is underdeveloped and the prognosis is worse than in most other heart defects. The underdevelopment can occur gradually during fetal growth caused by a narrowing of the aortic valve. At some international centers, such fetuses are treated with a balloon dilation of the narrowed valve, but there is no scientifically sound evidence that this treatment is effective. The aim of this study is: 1/ to evaluate whether balloon dilation during the fetal period of a narrowed aortic valve can reduce the risk of the left ventricle becoming underdeveloped and the baby being born with a so-called univentricular heart (HLHS); 2/ to investigate whether such treatment improves the prognosis for this group of children with a very complex and severe heart defect and 3/ to also describe side effects and risks in fetuses and mothers of the fetal procedure.
NCT04798430
The study is to assess the long-term safety, tolerability, and efficacy after 48 and 72 weeks with monthly (Q4W \[\<31 days\]) dosing of subcutaneous (SC) LIB003 300 mg administered in patients with CVD or at high risk for CVD (including HoFH and HeFH) on stable diet and oral LDL-C lowering drug therapy who completed one of the LIB003 Phase 3 base studies.
NCT05659264
The primary objective of this study is to evaluate the safety and tolerability of single and multiple doses at escalating dose levels of mRNA-0184.
NCT05058833
The DIAST-CMD registry (Prognostic Impact of Cardiac Diastolic Function and Coronary Microvascular Function) is prospective registry which enrolled patients who underwent echocardiography, cnically-indicated invasive coronary angiography and comprehensive physiologic assessments including fractional flow reserve (FFR), CFR, and IMR measurements for at least 1 vessel from Samsung Medical Center. Patients with hemodynamic instability, severe LV dysfunction (left ventricular ejection fraction\<40%), a culprit vessel of acute coronary syndrome, severe valvular stenosis or regurgitation were excluded.
