Dr. Robert Weiss directs a multi-disciplinary team at Johns Hopkins as well as collaborators at Cedars Sinai Medical Center in Los Angeles dedicated to identifying the most important clinical, genetic, structural, contractile and metabolic causes of sudden cardiac death as well as the means to reverse the underlying pathology and lower risk.
Energetic Consequences and Causes of Heart Failure -Predictors of Sudden Cardiac Death -Non-Invasive Magnetic Resonance -Role of Creatine Kinase in Heart Failure -Spectroscopy and Imaging -Coronary Endothelial Function -Small animal cardiovascular imaging
