Naringenin promotes angiogenesis of ischemic myocardium after myocardial infarction through miR-223-3p/IGF1R axis.

Introduction: Naringenin exerts a protective effect on myocardial ischemia and reperfusion. It has been reported that miR-223-3p is a potential target for the treatment of myocardial infarction (MI). In view of the unreported correlation between Naringenin and miR-223-3p, this study was designed to confirm that the ameliorative effects of Naringenin on MI is directly related to the regulation of miR-223-3p.

Prognostic value of the SYNTAX score on myocardial injury and salvage in STEMI patients after primary percutaneous coronary intervention: a single-center retrospective observational study.

Background: SYNTAX score (SS) was shown to positively correlate with postprocedural myocardial injury in patients after elective coronary artery intervention, but evidence about the association of SS with myocardial salvage in ST-segment elevation myocardial infarction (STEMI) patients is still needed. This study aimed to evaluate the prognostic value of SS for myocardial injury and salvage assessed by cardiac magnetic resonance (CMR) after primary percutaneous coronary intervention (PCI) in STEMI patients.

Methods: This single-center retrospective study consecutively enrolled STEMI patients who had undergone primary PCI within 12 h from symptom onset.

Different Changing Patterns of Three NOS-NO System Activities after Ischemia-Reperfusion in Rabbit with AMI.

NOS-NO system activity is closely correlated with ischemia-reperfusion injury (IRI) and NOS subtypes were suggested to play different roles in IRI. In this work, the activity of serum NOS, NO levels, and ischemic necrosis after reperfusion in rabbit with AMI at different time was studied. We also explored the NOS-NO system activity changes and its correlation with myocardial ischemia and necrosis.
