In cardiovascular diseases, myocardial infarction is the most important cause of chronic heart failure. According to reports, more than 70% of patients with chronic heart failure suffer from myocardial infarction. Nano sodium alginate-bioglass has attracted more and more attention in the treatment of myocardial infarction due to its good cell proliferation. In order to understand the effect of nano-sodium alginate-bioglass on myocardial infarction, we added nano-sodium alginate-bioglass in the treatment process. The calcium ions released by the bio-glass during the slurry preparation process partially crosslink the sodium alginate, which helps to restore the heart function of myocardial infarction. Add nanoseaweed Sodium-bioglass can significantly promote the proliferation of heart cells. Through the test of different groups and the results of cell experiments, we have obtained the best recovery effect of myocardial infarction when the bioglass content is about 30%, and the changes in the vitality of heart cells can be seen most clearly.
