Cardiovascular Disease

There are many different forms of cardiovascular (heart) disease.  The most common cause of cardiovascular disease is narrowing or blockage of the coronary arteries, the blood vessels that supply blood to the heart itself.  This is called coronary artery disease and happens slowly over time.  Other kinds of heart problems may happen to the valves in the heart, or the heart may not pump well and cause heart failure.  Some people are born with cardiovascular disease.

HeartMate PHP™ Coronary InterventionS in HIgh-Risk PatiEnts Using a Novel Percutaneous Left Ventricular Support Device (SHIELD II)

Prospective, randomized, multi-center, open-label trial of the HeartMate PHP at up to 60 sites in the US. Control device will be the Abiomed Impella® Recover® LP 2.5 Percutaneous Cardiac Support System.

Additionally, the study will include a nonrandomized roll-in phase at each site. Each site must first enroll and treat up to 3 patients in the nonrandomized roll-in phase before entering the randomized phase.

Assess the safety and efficacy of the HeartMate PHP in supporting patients with severe symptomatic coronary artery disease with diminished but stable cardiovascular function, who are undergoing elective or urgent high risk percutaneous coronary interventions (PCI) but are not candidates for coronary artery bypass graft (CABG) surgery.

Proposed Indications The HeartMate PHP System is a temporary (<6 hours) ventricular assist device indicated for use during high risk percutaneous coronary interventions (PCI) performed in elective or urgent,

hemodynamically stable patients with severe coronary artery disease and depressed left ventricular ejection fraction.  Nonrandomized Roll-In Phase: Up to 180 patients undergoing PCI per the Inclusion/Exclusion criteria; up to 3 roll-in patients per site.

Randomized Phase: Up to 425 patients undergoing PCI per the Inclusion/Exclusion criteria.

Data will be collected at baseline, during the PCI procedure, postprocedure, discharge, and 90 days post device removal.

All patients will have a follow-up visit at 90 days post-device removal.

Transcatheter Aortic Valve Replacement to UNload the Left ventricle in patients with ADvanced heart failure: a randomized trial  (TAVR UNLOAD)

The TAVR UNLOAD trial is an international, multi-center, randomized, open-label, clinical trial comparing the safety and efficacy of Transcatheter Aortic Valve Replacement (TAVR) with the SAPIEN 3 Valve and optimized heart failure therapy ( OHFT ) versus OHFT in heart failure (HF) patients, with moderate aortic stenosis ( AS). OHFT is defined as guideline-directed medical therapy. It can be medication only or a combination of medical therapy and approved HF devices.

Clinical efficacy of TAVR is assessed after 1 year of follow-up in all 600 patients. All patients are followed for 2 years to evaluate the value of the study device in to treat patients with Heart Failure (HF) who have moderate aortic stenosis (AS). The Edwards SAPIEN 3 Valve has already been approved by the FDA for use in patients who require an aortic valve replacement due to severe aortic stenosis

Connected Insights

Prospective observational study to assess association between time in target Flowtrac/EV1000 data with clinical outcomes in cardiac surgery patients (Connected Insights). The new study application will investigate a minimally invasive device (Flotrac sensor with EV1000 clinical platform) from Edwards Life Science in cardiac surgery patients.  The EV1000 device is already being used at Tufts Medical Center in the operating rooms and ICUs to guide fluid resuscitation and medicine administration in critically ill patients.

How Does Body Composition Change after Placement of a Left Ventricular Assist Device in Advanced Systolic Heart Failure?

Many patients with advanced heart failure describe loss of muscle mass and strength in their arms and legs. This process is known as ‘sarcopenia’ and has not been well studied in heart failure. In particular it is unknown whether the sarcopenia process can reverse after a heart failure patient receives a left ventricular assist device (LVAD, a surgically implanted heart pumpt). Therefore we are partnering with experts in nutrition and body composition at Tufts University to study changes in muscle mass, physical activity, food intake and metabolism in patients receiving an LVAD. Muscle mass is measured by two methods in the study, to help us determine which is the most accurate in heart failure patients: a dual-energy x-ray absorptiometry (DXA) scan and a non-radioactive isotope dilution technique. There are 3 study visits which each take a maximum of 4 hours, performed around the time of LVAD implant (30 days before to 21 days after), and at 3 months and 6 months after LVAD implantation.

Entrestotm (LCZ696) In Advanced Heart Failure (LIFE Study) (HFN-LIFE)

The purpose of this study is to test whether EntrestoTM, a newly approved drug for heart failure that combines sacubitril and valsartan, improves symptoms and outcomes in persons with advanced heart failure in comparison to treatment with valsartan alone over 24 weeks. EntrestoTM has been studied in only a very small number of patients with advanced heart failure, like you. This study is beind done to obtain more information on the benefits and risks of EntrestoTM in patients with advanced heart failure. Both EntrestoTM and valsartan have previously been approved by the U.S. Food and Drug Administration (FDA)for people with heart failurea nd are available by prescription from a licensed medical doctor. Currently EntrestoTM is only available under the brand name EntrestoTM, there is no generic form of EntrestoTM. You do not have to take part in this study in order to receive EntrestoTM.

A phase III randomised, double-blind trial to evaluate efficacy and safety of once daily empagliflozin 10 mg compared to placebo, in patients with chronic Heart Failure with reduced Ejection Fraction (HFrEF).

This is a prospective, multicenter, phase III randomized, double-blind trial to evaluate efficacy and safety of once daily empagliflozin 10 mg compared to placebo, in patients with chronic Heart Failure (HF) with reduced Ejection Fraction (HFrEF). The objective of this event-driven trial is to demonstrate superiority of empagliflozin 10 mg versus placebo in patients with symptomatic, chronic HF and preserved ejection fraction (LVEF ≤40%) under stable treatment of HF symptoms. Empagliflozin is an orally available, potent, and selective inhibitor of the renal SGLT-2. Its selective inhibition reduces renal reabsorption of sodium and glucose. This leads to both increased urinary sodium and glucose excretion. While the urinary sodium excretion returns to normal within few days of empagliflozin administration, the effect on urinary glucose continues. The study treatment period will run for approximately 20- 38 months, until the required number of adjudicated primary events are reached. In Addition to the treatment period there is a 4-21 day screening period and a 30 day follow up visit.
