Interval aerobic exercise training (treadmill running, alternated between 7 min at 25 m/min and 3 min at 15 m/min)‐induced increase in myocardial FSTL1 expression attenuates cardiac dysfunction in a rat model of myocardial infarction (Xi et al., 2016). Here, FSTL1 is linked to myocardial infarction.
