Although primary percutaneous coronary intervention (pPCI) is performed as the treatment of choice in Iranian hospitals, there is limited data on its efficacy, safety, procedural variations, and clinical outcomes after implementation of the new Protocol-247, which transfers patients with STEMI directly to pPCI-capable hospitals. The Primary Angioplasty Registry of Sina (PARS) is an ongoing prospective hospital-based registry enrolling patient with STEMI undergoing pPCI in Sina Hospital, which is a high-volume referral PCI-capable general hospital in Tehran, Iran. This registry aims to gather high-quality data on patient characteristics, hospital-based quality of care, coronary interventions, and in-hospital as well as long-term clinical outcomes of patients undergoing pPCI due to STEMI. In addition, the findings will be used to identify independent predictors of mortality and adverse events and form the basis of future clinical trials and quality improvement strategies. https://fem.tums.ac.ir/index.php/fem/article/view/531 https://fem.tums.ac.ir/index.php/fem/article/download/531/321
