Key result
Radial access primary PCI yields similar procedural success between high-risk and non-high-risk patients.
Why the study?
Predictors of favorable outcome after radial access primary PCI in STEMI patients, including high-risk groups, were not well defined.

Radial access primary PCI is a safe and highly successful reperfusion strategy for STEMI patients, demonstrating equivalent procedural efficiency in both high-risk and non-high-risk subgroups.
Radial primary PCI yielded high TIMI 3 flow without risk-group differences; supports feasibility in high-risk STEMI but leaves open need for randomized confirmation.
Background:ST-elevation myocardial infarction (STEMI) is a life-threatening condition requiring rapid reperfusion therapy. Primary percutaneous coronary intervention (PCI) via radial access has shown reduced bleeding complications and improved outcomes compared to femoral access. This study aimed to evaluate predictors of favorable outcome in patients undergoing radial access primary angioplasty.Methodology:This prospective observational study was conducted in the Department of Emergency Medicine at from May 2025 to January 2026. A total of 315 STEMI patients undergoing primary PCI through radial access were included. Patients were categorized into high-risk and non-high-risk groups based on predefined clinical criteria. Baseline characteristics, ECG, echocardiographic findings, procedural variables, complications, and outcomes were analyzed using SPSS version 25.0.Results:Of 315 patients, 112 were high-risk and 203 were non-high-risk. Most patients were male and in the 51–60 years age group. Diabetes mellitus (42.5%), hypertension (39.4%), and smoking (28.9%) were common risk factors. TIMI grade 3 flow was achieved in 86.03% of cases. No significant difference was observed between groups in fluoroscopy time (p=0.817) or contrast volume (p=0.547). Overall procedural success was high, with low crossover and complication rates.Conclusion:Radial access primary PCI is safe and effective in STEMI patients, including high-risk cases, with high procedural success and favorable outcomes.

Louis et al. (2026) conducted an observational in ST-elevation myocardial infarction (STEMI) (n=315). High clinical risk features vs. Non-high clinical risk features was evaluated on Achievement of TIMI grade 3 flow (p=0.120). Radial access primary PCI demonstrated a high overall procedural success rate (86.03% TIMI grade 3 flow), with no significant difference in achieving optimal flow between clinically high-risk and non-high-risk patients (p=0.120).
