Abstract
Myocardial infarction (MI) as a risky disease, raises the awareness of the public. It results in insufficient oxygen supply due to cardiovascular blockage and ultimately leads to extensive cell necrosis. Hence, biomaterial-based therapy, angioplasty, and cardiac patches are exposed for the two stages of MI and indicate a promising direction for future MI treatment. This paper focuses on the biomaterials applicable to them one by one, including (1) The crucial function of angioplasty in treating MI; the discussion of its efficacy, mechanics, and results; analysis of clinical studies, material improvements, procedural advancements, and both the effectiveness and limitations of angioplasty. (2) The application of cardiac patches for post-MI treatment; synthetic or natural patches with different structures; review and highlight how these patches promote tissue repair and functional recovery; and the advantages and disadvantages of each patch.
