Macrophage plasticity in cardiac inflammation warrants caution against fixed-phenotype assumptions; leaves open targeted polarization therapies.

To review the mechanisms of dynamic macrophage polarization and functional plasticity during cardiovascular adaptations to physical exercise.
Synthesized findings on temporal and spatial macrophage activation states in response to environmental cues, microbial challenges, and tissue stress.
Macrophage activation phenotypes operate as a continuum rather than fixed states, dynamically shifting functions across varying microenvironments.
Cues from damaged tissues and physiological stress guide macrophage phenotypic transitions relevant to cardiovascular remodeling.

Scheuer et al. (1977) studied this question.
