Coronary artery occlusion results in ischemic heart tissue and subsequent death of cardiomyocytes, followed by an inflammatory response to clear the infarcted area from dead cells. Invading inflammatory cells are suggested to contribute to myocardial ischemia-reperfusion (I/R) injury and adverse remodeling. Given the importance of the inflammatory phase during cardiac wound healing, better understanding is needed to develop novel interventions. In a recent study, researchers from University Medical Center Utrecht investigated the role of the inflammatory-related miR-223 in the ischemic heart using miRNA microarray technology...
