Professor of Medicine (Cardiovascular Medicine) and of Biomedical Engineering

Biography

Dr. Fadi G. Akar, Ph.D. completed his doctoral degree in Biomedical Engineering from Case Western Reserve University and his post-doctoral training in molecular cardiology at Johns Hopkins University. Dr. Akar joined the Faculty in the Department of Medicine at Johns Hopkins University in 2004, the Icahn School of Medicine at Mount Sinai in 2007 and Yale University School of Medicine in 2020. Dr. Akar's laboratory is dedicated to uncovering the mechanisms that promote arrhythmias in common structural heart diseases and to develop novel gene-based approaches to prevent these malignant arrhythmias.

Overview

The mission of the Akar Basic and Translational Arrhythmia Research Laboratory at Yale University is to advance our understanding of the basic biology of sudden cardiac death with a view towards identifying novel targets for treatment of acquired and congenital arrhythmic disorders. We seek mechanism-based molecular therapies for electrical diseases that are not amenable for treatment by conventional anti-arrhythmic approaches. We are actively pursuing studies on the pathophysiology of complex arrhythmias that arise in the following settings:

  • Hypertrophy and heart failure
  • Myocardial Infarction and ischemia-reperfusion injury
  • Obesity and diabetes mellitus
  • Atrial fibrillation
  • Pulmonary hypertension
  • Arrhythmogenic cardiomyopathy

The laboratory’s experimental pipeline consists of studies along the full translational scale from identifying novel targets through their validation in proof-of-concept studies and ultimately their advanced testing in pre-clinical large animal models. Ongoing studies in the lab include:

  • Target identification. These studies focus on identifying novel targets that control excitability and arrhythmias in the heart. For these, we use a combination of in vitro approaches, including heterologous cell lines, human inducible pluripotent stem cell derived cardiomyocytes (hiPSC-CMs), tissue engineered constructs and genetic mouse models (cardiac-restricted conditional knockdown and overexpression).
  • Target validation: These proof-of-concept studies rely on the use of cardiotropic gene delivery to uncover the electro-mechanical and structural effects of manipulating the expression of a given molecular target in rodent animal models.
  • Pre-clinical testing: These studies are designed to explore the efficacy of a given therapeutic strategy in either preventing or reversing arrhythmic risk in porcine models of cardiac disease using approaches that are readily translatable to humans.

Cognizant of lessons learned from the CAST and SWORD trials, we guide our work by the over-arching principal that effective and safe management of rhythm disorders requires interfering with the upstream root causes of the disease rather than the down-stream end-effectors of excitability (or the ion channels themselves). In that regard, we are interested in pursuing studies that elucidate fundamental mechanisms by which ion channel function is regulated by :

  • Metabolic signaling and mitochondrial bioenergetics
  • Mechano-transduction and mechano-electrical feedback
  • Biochemical cues
