Prodromal AP was associated with lower QRS scores in early STEMI; leaves open whether it extends the reperfusion window.
Does prodromal angina pectoris delay infarct progression (measured by QRS score) in patients with first ST-elevation AMI?
Prodromal angina pectoris may delay infarct progression during the early hours of AMI, potentially extending the time window for reperfusion therapy.
Maruhashi et al. (2010) studied this question.
