Personalized Cardiac Therapies


Ksenia Blinova, Ph.D.
David Strauss, M.D., Ph.D.


This group performs regulatory science research to improve the prediction of which patients will benefit from heart devices and therapies and which patients are likely to be harmed.

Three major areas of application for this research are:

  1. defining better patient selection criteria for cardiac resynchronization therapy (a special pacemaker for patients with heart failure) and implantable defibrillators,
  2. developing and testing novel biomarkers for heart toxicity, and
  3. using patient-specific induced pluripotent stem cell derived cardiomyocytes to predict personalized response to drugs.

Arrhythmias in induced pluripotent stem cell derived cardiomyocytes/

Arrhythmias detected in human induced pluripotent stem cell derived cardiomyocytes measured with a voltage-sensitive dye.

To this end, the group uses a translational medicine approach including:

  • whole heart and single cell cardiac models for medical devices safety and efficacy evaluation,
  • assessment of patient-specific induced pluripotent stem cell derived heart cells in precision medicine,
  • assessment of human induced pluripotent stem cell derived cardiomyocytes for evaluating drug-induced arrhythmias,
  • preclinical computational modeling/simulation,
  • patient studies to characterize individual patient characteristics,
  • individual-patient meta-analyses of clinical trials, and
  • post-market outcomes and comparative effectiveness research.

These diverse projects across different translational medicine areas are active collaborations with several researchers, both within the FDA and worldwide.

This research directly impacts the regulatory mission of the agency affecting:

  • FDA guidance documents and action plans,
  • acquired knowledge that supports pre-market submission reviews,
  • achieving the right balance between pre-market/post-market data collection,
  • disseminating science to improve the awareness of personalized medicine and facilitate innovative future products and methods,
  • development of new biomarkers, and
  • improvement of patient care in daily clinical settings.
