Hydrogel formulations for orthotopic treatment of myocardial infarction

INTRODUCTION: Myocardial infarction (MI) causes extensive structural and functional damage to the cardiac tissue due to the significant loss of cardiomyocytes. Early reperfusion is the standard treatment strategy for acute MI, but it is associated with adverse effects. Additionally, current therapies to alleviate pathological changes post-MI are not effective. Subsequent pathological remodeling of the damaged myocardium often results in heart failure. Oral drugs aimed at reducing myocardial damage and remodeling require repeated administration of high doses to maintain therapeutic levels. This compromises efficacy and patient adherence and may cause adverse effects, such as hypotension and liver and/or kidney dysfunction. Hydrogels have emerged as an effective delivery platform for orthotopic treatment of MI due to their high water content and excellent tissue compatibility. AREA COVERED: Hydrogels create an optimal microenvironment for delivering drugs, proteins, and cells, preserving their efficacy and increasing their bioavailability. Current research focuses on discovering functional hydrogels for mitigating myocardial damage and regulating repair processes in MI treatment. EXPERT OPINION: Hydrogels offer a promising approach in enhancing cardiac repair and improving patient outcomes post-MI. Advancements in hydrogel technology are poised to transform MI therapy, paving the way for personalized treatment strategies and enhanced recovery.
