Key result
Eosinophil deficiency following acute myocardial infarction resulted in enhanced myocardial inflammation, increased scar size, and deteriorated cardiac function, which was prevented by interleukin-4.
Why the study?
Does eosinophil deficiency affect myocardial repair and adverse remodeling following acute myocardial infarction?
Population
Patients and mice with ST-segment elevation myocardial infarction
Comparison
Eosinophil deficiency vs normal eosinophil levels and interleukin-4 therapy

Eosinophil depletion after STEMI associates with worse remodeling; hypothesis-generating for IL-4 as a therapeutic target.
Does eosinophil deficiency affect myocardial repair and adverse remodeling following acute myocardial infarction?
Eosinophils play a protective role in post-myocardial infarction repair, and their deficiency leads to adverse remodeling that can be rescued by interleukin-4 therapy.
Toor et al. (2020) studied ST-segment elevation myocardial infarction. Eosinophil deficiency was evaluated on Myocardial inflammation, scar size, and myocardial structure and function. Eosinophil deficiency following acute myocardial infarction resulted in enhanced myocardial inflammation, increased scar size, and deteriorated cardiac function, which was prevented by interleukin-4.
