Conclusion
CAR, an inflammatory marker in patients with STEMI, is known to influence the rates of mortality and morbidity. However, the relationship between CAR and IRA patency has not been investigated. This is the first study to reveal a significant relationship between the IRA patency and CAR before p-PCI in STEMI. The C-reactive protein/albumin ratio is an easy and reliable indicator that can be used to determine IRA patency in patients with STEMI.
