In addition to a lack of diagnostic strategies, there is a paucity of research into therapeutic strategies. Most women are conservatively managed with medications, however, there is no consensus as to which pharmacologic therapies should be used. Case reports have suggested benefit with antiplatelet agents (e.g. aspirin) and beta-blockers (reduction of arterial wall shear stress). To date no study has investigated the effects of statins or Angiotensin Converting Enzyme Inhibitors (ACEIs) in SCAD patients. Both agents have been studied in the MCD population and been found to reduce angina frequency and improve CFR after 16 weeks.
