Does previous angina improve in-hospital outcome after acute myocardial infarction?
Previous angina is associated with better in-hospital outcomes following acute myocardial infarction, possibly due to ischemic preconditioning.
Previous angina confers a beneficial effect on in-hospital outcome after acute myocardial infarction. The reasons for this benefit are uncertain, but one potential mechanism for this observation may be ischemic preconditioning.
Kloner et al. (Sun,) studied this question.
