Kudos to Assistant Professor Jessica Zegre-Hemsey, who presented “Pulse oximetry parameters to augment detection of myocardial ischemia – a feasibility study” to an international audience at the International Society for Computerized Electrocardiology annual conference in St. Simon’s Island, Georgia, April 19-23, 2017.In this pilot study, Zegre-Hemsey worked with Brant Nix to examine the peripheral perfusion index (PPI), a measure that is routinely collected through non-invasive pulse oximetry monitoring in a variety of clinical settings, as a novel biomarker to augment the detection of acute coronary syndrome. PPI reflects increased systemic vascular resistance, which is associated with acute myocardial ischemia/infarction (the underlying mechanism for acute coronary syndrome [e.g. heart attacks]).
Dr. Zegre-Hemsey’s study was conducted in the SON Biobehavioral Laboratory and these results will drive future research among individuals hospitalized for acute coronary syndrome. Both rapid and accurate identification of acute coronary syndrome are important because timely treatment is directly associated with improved patient outcomes.
The International Society for Computerized Electrocardiology is a highly interdisciplinary group comprised of nurses, physicians, engineers and industry all whom share the common goal of advancing electrocardiology through the application of computer methods to enhance care of individuals with heart disease, the top killer of Americans.
