Research Focus

The Goldhaber lab's NIH and AHA-supported research is studying the regulation of cardiac excitation-contraction coupling in health and disease, with a particular focus on the effects of metabolic inhibition, ischemia and heart failure on sodium-calcium exchange. A new area of interst is the genesis of pacemaker activity in the sinus node. This has led to a new NIH-funded project to unravel the mysteries of the heart¿s natural pacemaker activity using laser scanning confocal microscopy, voltage mapping, and single cell electrophysiology using the patch clamp technique.

Research Contributions

Dr. Goldhaber was among the first to describe the effects of metabolic and oxidative stress on cardiac excitation-contraction coupling and calcium regulation. He was also a leader in the study of sodium-calcium exchange and its effects on excitation-contraction coupling in genetically modified mice.

Current investigations include:

-Cardiac Excitation-Contraction Coupling in Ischemic and Failing Myocytes
-Effects of Metabolic and Oxidative Stress on Cardiac Excitation-Contraction Coupling
-Role of Sodium-Calcium Exchanger in Excitation-Contraction Coupling
-Sinoatrial Node Pacemaking Dependence on Sodium-Calcium Exchange
-Structure-Function of the Sodium-Calcium Exchanger
