Patient Age Group
Provider Gender


After finishing college, medical school and graduate school at Harvard Medical School, I graduated with an MD-PhD in 2000. I completed my training in internal medicine, cardiovascular sciences and clinical electrophysiology at Massachusetts General Hospital, where I am was on staff from 2007-2011. I was then at Beth Israel Deaconess Medical Center as the Co-director of the Cardiovascular Genetics Center and ran an active research program on RNA biomarkers for heart failure and arrhythmias.

I was recruited back to MGH and am the co-director of the Resynchronization and Advanced Cardiac Therapeutics Program.  I am seeing general cardiac arrhythmia patients, with a special emphasis on patients with inherited arrhythmias, cardiomyopathies and sudden cardiac death.

My research focuses on understanding mechanisms of arrhythmias in heart failure, discovering new tests to provide better identification of patients at risk of developing heart failure or arrhythmias, and uncovering new therapies to treat heart failure.  I see patients with a range of cardiac arrhythmia problems, including heart failure, supraventricular arrhythmias and sudden cardiac death.

Research & Publications

Research Summary

View my most recent research

My research focuses on discovering new types of blood markers that can help predict patients who develop worsening heart failure or arrhythmias. My laboratory has optimized new methods to visualize and study vesicles in the blood that can carry some of the markers and transfer them between different organs as a new type of signaling.

We use the discovery of these new types of blood markers to study their functional role in mediating heart disease progression and are trying to develop new types of therapies to halt the progression of heart failure and arrhythmias. 

News & Events

  • Non-Coding RNAs Serve as Biomarkers for Cardiovascular Disease

    Non-coding RNAs were once considered of little use.. Researchers led by Saumya Das at Mass General are identifying RNA prognostic biomarkers for cardiovascular diseases.

  • New Strategies for Heart Failure Patients

    Cardiac resynchronization therapy (CRT) is one of the most common treatments for patients with moderate to severe heart failure, and it involves placing a biventricular pacing device to resynchronization contraction of the heart’s ventricles.
