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.

NCT01850082
Coronary artery bypass grafting (CABG) is the most common major surgical procedure in the United States with over 300,000 cases performed each year. To restore blood flow to the heart, vascular conduits from another part of the body are procured to create a bypass around critically blocked coronary arteries. The left internal thoracic artery is the conduit of choice for CABG due to its superior long-term patency. However, almost all patients referred for CABG require additional grafts to provide complete revascularization. This necessitates the harvest of other vessels, most commonly the saphenous vein which is used almost ubiquitously in contemporary CABG with an average of two vein grafts per CABG procedure. In the last 10 years, Endoscopic Vein Harvesting (EVH) has been recommended as the preferred method over the traditional open harvesting technique (OVH) because it provides a minimally invasive approach. However, more recent investigations indicate potential for reduced long-term bypass graft patency and worse clinical outcomes with EVH. The long term impact of EVH on clinical outcomes has never been investigated on a large scale using a definitive, adequately powered, prospective Randomized Controlled Trial (RCT) with long-term follow-up.
NCT04648306
A multi-center, prospective, observational, non-interventional single arm, study of the intermediate-term clinical outcomes collected from electronic health records of high-risk patients which have previously undergone standard of care prophylactic Impella support for a non-emergent percutaneous coronary intervention (PCI).
NCT02104817

NCT02026466
This is an observational registry, sponsored by Saint Luke's Hospital. This study is to be conducted according to DHHS Guidelines, applicable state regulations, and local IRB policies and procedures. The overall objective is to address current gaps in knowledge regarding CTO-PCI, as a prospective, multi-center, single-arm study of 1,000 participants.
NCT02929329
The purpose of this study is to determine if treatment with omecamtiv mecarbil when added to standard of care is well tolerated and superior to placebo in reducing the risk of cardiovascular death or heart failure events in adults with chronic heart failure with reduced ejection fraction (HFrEF).
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)
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.
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.
NCT00121472
The purpose of this study is to determine the safety and effectiveness of the Thoratec HeartMate II Left Ventricular Assist System (LVAS) as a bridge to cardiac transplantation in end-stage heart failure patients who are listed for cardiac transplant but are at imminent risk of dying. The HeartMate II LVAS was approved by the US FDA on April 21, 2008, as a bridge to cardiac transplantation (reference PMA P060040). It was approved for commercial distribution in Canada on May 20, 2009 (reference Medical Device Licence #79765). Patients enrolled into the clinical trial will continue to be followed until all have reached a clinical outcome.
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.
NCT01925794

This study will enroll patients with symptomatic ischemic heart disease due to a single de novo lesion contained within a native coronary artery with reference vessel diameter between 2.5 mm and 4.0 mm and lesion length ≤ 24 mm that is amenable to percutaneous coronary intervention (PCI) and stent deployment. All patients will be followed at 30 days, 6 months, 9 months, 1 year and annually for 5 years post index stenting procedure.
NCT02957409
The purpose of the study is to describe the heart failure with reduced ejection fraction (HFrEF) patient population receiving sacubitril/valsartan treatment.
NCT00039975
Diltiazem CD and amlodipine are drugs used to treat heart disease and high blood pressure. The purpose of this study is to find out if these drugs interact with the anti-HIV drugs indinavir and ritonavir. The study will also look at the safety of taking the study drugs together. Heart disease and high blood pressure are major health concerns for people with HIV. Standard treatment for these illnesses often includes calcium channel blockers (CCBs). There is a potential for significant drug interactions between CCBs and HIV protease inhibitors (PIs) that may influence the dosing, monitoring, and choosing of CCBs and PIs when used in people infected with HIV. This study will examine the drug interactions between 2 commonly used CCBs and the PI combination indinavir and ritonavir (IDV/RTV). This information should help doctors choose the appropriate treatment for high blood pressure or heart disease in people taking PIs.
