Ropivacaine and celecoxib-loaded injectable composite hydrogel for improved chronic pain-exacerbated myocardial ischemia-reperfusion injury.

Chronic pain is a prevalent condition affecting a significant portion of the global population and is known to be associated with an increased risk of cardiovascular diseases. Despite the clinical relevance, the mechanisms underlying the link between chronic pain and myocardial ischemia-reperfusion (MI/R) injury remain poorly understood. This study aimed to investigate the role of the superior cervical ganglion (SCG) in mediating the effects of chronic pain on MI/R injury and to develop a novel therapeutic strategy.

Upregulation of P2X7 Exacerbates Myocardial Ischemia-Reperfusion Injury through Enhancing Inflammation and Apoptosis in Diabetic Mice.

Diabetes-aggravated myocardial ischemia-reperfusion (MI/R) injury remains an urgent medical issue, and the molecular mechanisms involved with diabetes and MI/R injury remain largely unknown. Previous studies have shown that inflammation and P2X7 signaling participate in the pathogenesis of the heart under individual conditions. It remains to be explored if P2X7 signaling is exacerbated or alleviated under double insults.
