Spontaneous coronary artery dissection (SCAD) is an important but under-recognized cause of acute coronary syndromes, particularly among young women without traditional cardiovascular risk factors. The 2018 American Heart Association statement on management of SCAD recommends early diagnosis for this condition because treatment differs from typical acute coronary syndromes due to atherosclerotic disease. Members of the UT Southwestern Division of Cardiology have a particular interest in SCAD and have participated in the International SCAD (iSCAD) Registry, a robust collaboration of SCAD researchers around the globe.
At #AHA22, we presented an analysis from the iSCAD Registry that focused on diagnostic delays among SCAD patients. We were interested in understanding delays in patient presentation to the hospital after onset of symptoms, as well as delays in establishing a definitive diagnosis with a coronary angiogram once patients were admitted to the hospital. Delays in patient presentation to the hospital and in coronary angiography were defined as more than 24 hours from onset of symptoms or presentation to the hospital, respectively.
“Non-white race was associated with a delay in performing invasive coronary angiography after hospital admission. This association was not explained by disease severity at the time of presentation.”
