Dr. Haigney is a board certified cardiologist and electrophysiologist who attends in the Walter Reed Cardiology and Genetic Cardiology clinics. The Haigney Cardiovascular Laboratory is primarily concerned with identifying mechanisms of sudden cardiac death, including those related to genetically transmitted arrhythmia syndromes. The lab combines basic and clinical investigations in a translational approach. A tachycardia-pacing model of large animal heart failure has been in place for ten years and has allowed evaluation of specific ion channels and their alteration by heart failure. The clinical research component has evaluated a number of approaches to prediction of arrhythmic events, with particular emphasis on unstable repolarization as manifest by QT interval variability. The laboratory has investigated the use of inducible pluripotent stem cell derived myocytes to understand the mechanisms of cardiac arrest in human subjects. Dr Haigney is the Director of the newly-established Military Cardiovascular Outcomes Research (MiCOR), a program intended to understand the impact of military service- particularly stress, weight-gain, exercise, and pharmacotherapy- on cardiovascular risk. He is the Deputy Director of the Collaborative Health Initiative Research Program (CHIRP), an NIH and DoD sponsored center for evaluating genomics in the military health system. Dr. Haigney is particularly interested in iatrogenic factors contributing to sudden death, including the impact of prescription medications, particularly synthetic opioids, and sympathomimetic supplements.
