[1] However, in realworld clinical practice, the implementation of PPCI faces substantial operational challenges, particularly in resource-limited settings, such as inadequate availability of specialized cardiac catheterization teams with requisite procedural expertise or the complete absence of coronary intervention capabilities in numerous rural healthcare facilities across China. [2] Consequently, fibrinolytic therapy remains the predominant reperfusion strategy for STEMI management in county-level hospitals, with particularly high utilization rates observed in geographically remote regions. [3,4] Furthermore, our previous study revealed that 42.5% of STEMI patients fail to receive any form of evidence-based reperfusion therapy, representing a critical gap in optimal care delivery. [3] To elucidate the prognostic implications of these treatment pathways within China’s unique healthcare system, this study aimed to compare the long-term outcomes among STEMI patients receiving PPCI, fibrinolysis, and no reperfusion therapy using data from the China Acute Myocardial Infarction Registry (CAMI Registry, [clinicaltrials.gov](clinicaltrials.gov), NCT01874691).  \n\n| Access this article online |  |\n| --- | --- |\n| Quick Response Code: | Website:\u003Cbr>[www.cmj.org](www.cmj.org) |\n|  | DOI:\u003Cbr>10.1097/CM9.0000000000003836 |\n\nThe CAMI Registry is a prospective, nationwide, multicenter observational registry study for patients with acute myocardial infarction (AMI) from 108 hospitals across 31 provinces and municipalities in China.
