They should be essential in everyday clinical decision making. Decreased coronary blood flow is multifactorial. Research in this field has been dramatically advanced by the development of laboratory-induced pluripotent stem cells (iPSCs) that harbor the capability to become any cell . Posterior infarction accompanies 15-20% of STEMIs, usually occurring in the context of an inferior or lateral infarction. Definition of myocardial infarction.
