Article Abstract
Background: Cardiac computed tomography angiography derived fractional flow reserve (FFR) is a diastolic measurement and has emerged as a valuable non-invasive alternative to FFR in patients with stable coronary artery disease. It has, unlike FFR during coronary angiography, not been validated for the physiological evaluation of an isolated myocardial bridge (MB) so far.
Case Summary: Our patient, previously known with a long myocardial bridge of the mid-segment of the left anterior descending artery, presented with a non-ST-segment elevation myocardial infarction that was treated by surgical unroofing of the MB. FFR after surgery confirms a major amelioration of coronary blood flow.
Discussion: Myocardial bridge may rarely present as a non-ST-segment elevation myocardial infarction. FFR has thus far been accepted as a useful diagnostic tool in stable coronary artery disease. Our case report suggests that cardiac computed tomography angiography may be considered a useful technique for anatomical and physiological evaluation of MBs.

Liraglutide is a key therapeutic agent in managing type 2 diabetes mellitus (T2DM), with benefits extending beyond glycemic control to address cardiovascular and renal comorbidities. As T2DM prevalence rises globally, the need for medications that provide comprehensive health benefits becomes increasingly important. Liraglutide, a GLP-1 receptor agonist, has demonstrated effectiveness in reducing cardiovascular events, especially among patients with high cardiovascular risk, such as those with a prior history of myocardial infarction or stroke.

Acute myocardial infarction (AMI) is one of the main causes of mortality worldwide. Currently, the most effective treatment is percutaneous coronary angioplasty (PCA). However, paradoxically, the restoration of blood flow induces myocardial reperfusion injury (MRI), contributing up to 50% of the final infarct size.

Introduction: A myocardial bridge (MB) is a condition where a segment of an epicardial coronary artery passes through the myocardial muscle. While traditionally regarded as benign, MBs have been associated with various cardiovascular conditions. Therefore, assessing their hemodynamic impact is crucial for informed treatment decisions.

Mitigating myocardial ischemia-reperfusion (IR) injury is essential for enhancing the success of heart transplantation (HT) and improving patient outcomes. During HT, infiltrating neutrophils are influenced and regulated by various other cell types, contributing to myocardial IR injury through the excessive release of neutrophil extracellular traps (NETs). Nonetheless, the precise mechanisms underlying the interactions between neutrophils and other non-cardiomyocytes remain largely unexplored.

Mitochondrial DNA (mtDNA) acts as a damage-associated molecular pattern to activate the stimulator of interferon genes (STING) signaling in macrophages, promoting tissue inflammation. However, its role in acute myocardial infarction (AMI) remains unclear. Macrophage-specific knockout mice were used to validate STING's pathological role in AMI.
