This study demonstrates macrophages' role in cardiac function and fibrosis in myocardial infarction, indicating therapeutic potential.

To investigate the role of cardiac macrophages in fibrosis following myocardial infarction.
Examined macrophage phenotypes and functions in post-infarction tissue.
Identified cellular origin and location of macrophages in the ischemic heart.
Evaluated the impact of macrophage activity on fibrotic scar formation and cardiac function.
Macrophages remain in the fibrotic scar post-infarction and influence its size.
A subset of monocytes differentiated into macrophages contributing to tissue repair.
Macrophage activity correlates with preserved cardiac function post-myocardial infarction.

Rodriguez et al. (2025) studied this question.
