NGF and myocardial ischemia: Whether cardiomyocyte necrosis is permanent or not is of great significance for the prognosis of a patient.15 At this time, capillary growth has a positive effect on the reactivation and nutrition supply of cardiomyocytes, and NGF mentioned in this study is an important biological indicator for capillary neogenesis.16 Tirofiban has an obvious inhibitory effect on platelet agglomeration, so it has positive efficacy in preventing cardiac ischemia and complications related to sudden coronary occlusion.
