Research + Clinical Trials
Hypertrophic Cardiomyopathy (HCM) is a genetic disease where the heart muscles become thicker because of the disease. We use electrocardiogram, echocardiogram or cardiac magnetic resonance imaging (CMR) tests to see if someone might have HCM. Another disease, transthyretin cardiac amyloidosis (ATTR-CM) can also cause the heart to become thick and look similar to HCM on these tests (usually in patients who are over 60 years old).
Recent research suggests that up to 10% of patients ≥ 60 years of age who have been diagnosed with HCM, may actually have ATTR-CM. However, no formal research study has been done to confirm if this is what is happening. Standard practice at Tufts is that patients ≥ 60 years of age have routine testing for HCM (including electrocardiogram, echocardiogram, and CMR) and a special test (called a pryophosphate scan) specifically to evaluate for ATTR-CM. This is important as ATTR-CM is treated differently than HCM.
The research team is inviting participants to be included in a registry in order to look at the difference between the two diseases and how they are diagnosed. This study's registry is a compilation of various cardiac images, lab tests, and medical histories of patients with HCM and ATTR-CM. If they choose to participate, they will be included in a registry using the following information: clinical history, lab tests, echocardiogram, cardiac magnetic resonance imaging (CMR), and pyrophosphate scan. We will look at this information to understand how often patients originally diagnosed with HCM were later diagnosed with ATTR-CM instead.

At Tufts Medical Center, we are continually evaluating different approaches to monitor and improve the care of our patients with advanced systolic heart failure. We are currently partnering with a company that has developed a non-invasive probe that measures capillary oxygenation through the skin. The probe attaches to the skin with a temporary adhesive and records the amount of oxygen in the blood cells passing through the skin. This technology may help us to detect when patients with abnormal heart pumping function (heart failure) are not circulating enough blood to their body. We have designed a study using this non-invasive probe to measure capillary oxygenation during exercise stress tests in patients with systolic heart failure and without systolic heart failure. Both groups of patients will have already been scheduled to undergo a treadmill exercise tests for standard clinical indications at Tufts Medical Center. We attach the adhesive probe to the skin on the base of the thumb and on the forearm during the exercise test. Study participation ends at the conclusion of the stress test, and the adhesive probe is removed. We hope to identify the differences between blood supply to the skin during exercise in patients with normal heart function versus those with systolic heart failure.

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.
