Research Areas

research overview

Dr. Tilkemeier's research is primarily focused on the applications of imaging in patient care as well as predicting quality. His interests in the field of cardiac rehabilitation have focused on behavioral modification and the benefits of cardiac rehabilitation from a behavioral model including depression, anxiety and compliance with a long-term cardiac rehabilitation program. His other interests focus on the application of standards in imaging techniques, particularly nuclear cardiology.

research statement

The research that Dr. Tilkemeier has performed has focused on nuclear cardiology and its applications in clinical practice. These have included participation in numerous local trials, evaluating patients with coronary disease and their variable responses to exercise and imaging. Additionally, new techniques in imaging, such as gated SPECT and advanced image processing, have been investigated and published. These areas have also resulted in numerous presentations, both nationally and internationally. As a result of this expertise, Dr. Tilkemeier has authored two self-assessment programs for the American Society of Nuclear Cardiology.

In the field of Cardiac Rehabilitation, Dr. Tilkemeier has participated in multiple NIH trials, which have focused on the cognitive function and outcomes of multiple participants in cardiovascular rehabilitation. These have looked at numerous risk factors, including depression, anger, hostility and their implications for well-being at the completion of cardiac rehabilitation. Current and future research has been focused on the delivery model of cardiac rehabilitation to emphasize compliance for the long-term.

A third area of interest has been in the development of national standards for image exchange and reporting. This involves working with multiple national committees, vendors and organizations to ensure that the necessary tools are available for widespread implementation of image exchange.
