Applications and Challenges of Stage-Specific Microenvironment-Responsive Hydrogels for Myocardial Infarction.
Myocardial infarction (MI) progresses through a series of distinct pathological stages, from acute ischemia and reperfusion injury to chronic inflammation, fibrotic proliferation, and ventricular remodeling, each characterized by a unique combination of microenvironmental cues and therapeutic demands. Traditional injec...
