What is IRA in cardiology?

In cardiology, IRA stands for "Infarct-Related Artery," which refers to the coronary artery that is occluded during a myocardial infarction (heart attack). Identifying the IRA is crucial for determining the appropriate treatment strategy, such as percutaneous coronary intervention (PCI) or thrombolysis, to restore blood flow to the affected heart muscle. Effective management of the IRA can significantly improve patient outcomes and reduce the extent of heart damage.
