Chapter 47 - Hidden Killer of the Healthy - An "Intimal" Discussion of Spontaneous Coronary Arter...

Dr Sharonne Hayes, Professor of cardiovascular medicine and founding director of Mayo Clinic women’s heart clinic, and Dr. Marysia Tweet, Associate Professor of cardiovascular medicine, and co-leader of the Spontaneous Coronary Artery Dissection Registry and leader in women’s heart health join the show for this amazing November chapter of Always on EM. They are world experts on Spontaneous Coronary Artery Dissection authoring over 60 peer reviewed articles on the topic and in this chapter we explore with them the pitfalls and pearls related to making this diagnosis in the ED. SCAD is an important cause of myocardial infarction especially in patients who would not otherwise seem to be at risk for heart attacks for example active young women without comorbidities, and its imperitive that we as emergency physicians are current on this diagnosis.
