Associate Professor of Medicine (Cardiology)
The University of Texas Medical School at Houston
Dr. Nils Johnson, M.D., M.S., is an Associate Professor of Medicine in the Division of Cardiovascular Medicine at The University of Texas Medical School at Houston and the Weatherhead P.E.T. Imaging Center. He completed medical school at Columbia University in New York then moved to Northwestern University in Chicago for internal medicine residency, cardiology fellowship, and interventional cardiology fellowship. He also earned a Master of Science degree in epidemiology and biostatistics from the Department of Preventive Medicine at Northwestern.
His research with mentor K. Lance Gould, M.D., started in 1999 and focuses on clinical coronary physiology, from patient to perfusion to pill and/or PCI. Their fundamental question is “when” to perform revascularization, as opposed to the “how” that has historically dominated cardiology. Currently he works on routine non-invasive measurement of absolute flow and its clinical application in the randomized Century Health Study of comprehensive CAD management.
He received a Seed Grant from the American Medical Association in 2004 to study P.E.T. perfusion heterogeneity. While at Northwestern he was funded through their physician-scientist training program. He was a Samuel A. Levine Young Clinical Investigator Award finalist at the AHA in 2009 for work on QT dynamics. In March 2012 at ACC.12, he received a Parmley Prize (young author award) from JACC Cardiovascular Imaging for a publication on the low-flow thresholds that produce ischemia.
His clinical interests include deciding when invasive aniography, cardiac catheterization, angioplasty (stent), or bypass surgery is necessary by using non-invasive tools like cardiac P.E.T. imaging or invasive tools like FFR.
Dr. Johnson is board certified by the American Board of Internal Medicine, with Subspeciality Boards in Cardiovascular Disease, Interventional Cardiology, and Nuclear Cardiology.
