 Understanding the impact of exercise training on left ventricular and coronary artery electrophysiological and morphological remodeling in heart failure.

The primary focus of my research is to understand the impact of exercise training on the myocardium and coronary arteries of the failing heart.  The main goals of the lab are to determine the intensity and frequency of exercise that may provide benefits in heart failure patients and the cellular mechanisms underlying these changes.  Cardiac function is compromised in heart failure, thus, the level of exercise that these patients are able to perform and still gain health benefits is likely to be very different from other patient populations.  It is our hope that the elucidation of these changes will allow physicians to better utilize exercise as a therapeutic modality in a clinical setting of heart failure.

Currently, the research efforts in my lab are focused on understanding the effect of exercise on electrophysiological remodeling, specifically K+ and Ca2+ ion channels, and their impact on vascular function in the coronary arteries of failing hearts.  We are also examining changes to left ventricular fibrosis in heart failure following exercise.  Recently, we have discovered exercise reduces cardiac fibrosis and maintains normal coronary vascular function as a result of preventing the loss of Ca2+-sensitive K+ current.

My laboratory currently uses catheter techniques and ultrasound to measure cardiac and coronary vascular function in vivo and patch clamping, cannulated vessel preparations, histology, and biochemical techniques to study the mechanisms and impact of exercise in heart failure.
