Research summary: 
Robert J. Gajarski, M.D. is a board-certified pediatric cardiologist whose primary research focus involves advancing the science of cardiac transplantation. This includes participation in new immunosuppression drug trials, long-term outcomes research and assessment of graft rejection and coronary vasculopathy using newer non-invasive imaging modalities coupled with gene-expression profiling. Currently, the transplant group is collaborating with a national consortium of pediatric transplant centers to investigate reasons and risk factors for adverse outcomes among patients with cardiomyopathy who undergo transplantation.  The group is also evaluating quality of life (QOL) indicators in transplant patients and, based on that data, beginning to develop interventional strategies to facilitate the transition from pediatric to adult care while improving self-management skills for each patient.
 
Working in the cardiac ICU, Dr. Gajarski is also investigating neuro-hormonal dysfunction in cardiac surgery patients post-bypass and the potential benefits of tight glycemic control following cardiac surgery.  In addition, as part of a core group of cardiac intensivists, he is collaborating with a larger institutional group (M-CHORD) to assess long-term outcomes and QOL after congenital surgical repairs as well as physiology-based and quality-improvement initiatives in the cardiac ICU.
