NCT01934985
The investigators propose a 4 year prospective, observational study of 40 patients yearly, comparing conventional clinically indicated SPECT and PET perfusion with dynamic rest/stress MPI studies with coronary angiography, in some cases performed with quantitative coronary anatomy and flow as well as quantitative 13N-ammonia PET MPI. Methods will also be assessed for their ability to determine myocardial viability by comparing regional wall motion (WM) on clinically indicated serial ventriculography, echocardiography or gated SPECT MPI in those protocol patients with WM abnormalities who subsequently undergo revascularization. Patient studies will begin in the first study year based on those methods already developed and integrate new advances as they become evident.

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)
NCT03882788
The purpose of this study is to assess whether the type of anesthesia, narcotic-based versus inhalational anesthesia administered during cardiopulmonary bypass (CPB) surgery contributes to the wide variation in neurologic recovery and developmental outcome after surgery in infants with congenital heart disease.
NCT03579641
The goal of the PREEMPT-HF study is to collect device and clinical event data to evaluate extended applications of the HeartLogic Heart Failure Diagnostic (HeartLogic) in a broad spectrum of heart failure patients with an implantable cardioverter defibrillator or cardiac resynchronization therapy defibrillator. There are no primary safety and/or efficacy endpoints for this study. Heart failure is a complex clinical syndrome with high morbidity, mortality, and economic burden. Chronic Heart Failure is persistent, gradually progressive, and punctuated by episodes of acute worsening leading to hospitalizations. Therefore, there remains an unmet clinical need to slow the progression of Heart Failure and prevent hospitalizations. HeartLogic, available in Boston Scientific cardiac resynchronization therapy devices and defibrillators, combines novel sensor parameters such as heart sounds and respiration with other measurements like thoracic impedance, heart rate, and activity into a HeartLogic Index for the early detection of worsening Heart Failure. However, there is limited data on the association of HeartLogic with the risk of Hear Failure readmissions and tachyarrhythmias, or for phenotyping the broad spectrum of Heart Failure patients.
NCT04789278
This is a multi-center, randomized quality improvement project. At least 200 statin-naïve patients without a history of atherosclerotic cardiovascular disease with incidental coronary artery calcium (CAC) on a prior non-gated chest CT will be enrolled across the Stanford Healthcare System and the Palo Alto Veteran's Affairs Healthcare System. Patients will be randomized in a 1:1 fashion to notification or usual care arms. The primary aim of this project is to estimate the increase in 6-month statin prescription among statin-naïve patients without a history of atherosclerotic cardiovascular disease with incidental CAC on a non-gated chest CT who are randomized to receive notification of their findings vs. usual care.
NCT01452802
The purpose of this study is to evaluate and compare the effectiveness of the HeartMate II (HM II) Left Ventricular Assist Device (LVAD) support versus OMM in ambulatory NYHA Class IIIB/IV heart failure patients who are not dependent on intravenous inotropic support and who meet the FDA approved indications for HM II LVAD destination therapy.
NCT03082729
The purpose of the VIP-A study is to determine the effect of apremilast on aortic vascular inflammation, cardiometabolic biomarkers and body composition in patients with moderate-severe psoriasis.
NCT04157751
This is a study in adults who are in hospital for acute heart failure. The purpose of this study is to find out whether starting to take a medicine called empagliflozin soon after first being treated in hospital helps people with acute heart failure. Participants are in the study for about 3 months. At the beginning, participants are still in hospital. Later, they visit the hospital about 3 times and get 1 phone call. Participants are put into 2 groups by chance. One group takes 1 empagliflozin tablet a day. The other group takes 1 placebo tablet a day. Placebo tablets look like empagliflozin tablets but do not contain any medicine. Empagliflozin belongs to a class of medicines known as SGLT-2 inhibitors. It is used to treat type 2 diabetes. During the study, the doctors check whether participants have additional heart failure events like needing to go to the hospital again because of heart failure. The participants answer questions about how their heart failure affects their life. We then compare the results between the empagliflozin and placebo groups. The doctors also regularly check the general health of the participants.
NCT02468778
The HeartMate PHP System is a temporary (\<6 hours) ventricular assist device indicated for use during high-risk percutaneous coronary interventions (PCI) performed electively or urgently in hemodynamically stable patients with severe coronary artery disease, when a heart team, including a cardiac surgeon, has determined high-risk PCI is the appropriate therapeutic option. Use of the HeartMate PHP Systems in these patients may prevent hemodynamic instability, which can result from repeat episodes of reversible myocardial ischemia that occur during planned temporary coronary occlusions and may reduce peri-and post-procedural adverse events.
NCT03988166
The objective of this study is to evaluate angiographic confirmation of placement of any guidewire beyond the CTO, in the true vessel lumen, in patients undergoing CTO percutaneous coronary intervention (PCI) in which at least one Teleflex guidewire and at least one Turnpike catheter are used.
NCT04828590
DEEPVESSEL FFR is a medical device that is designed to extract three- dimensional coronary tree structures and generate computed tomography-derived fraction flow reserve (FFR) values from coronary CT angiogram images. The primary objective of this multi-center clinical validation study is to validate the clinical performance of DEEPVESSEL FFR in identifying patients with myocardial ischemia due to significant obstructive coronary artery diseases.
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.
