Abstract
BACKGROUND: The use of radial approach for coronary angiography, followed by same-day inter-facility transfer for percutaneous coronary intervention (PCI) has not yet been evaluated. OBJECTIVES: We sought to assess the safety and feasibility of using the transradial as compared to the transfemoral approach in patients undergoing diagnostic angiogram with same-day transfer to a PCI facility. METHODS: Patients that underwent diagnostic coronary angiography between January 2011 and June 2017 in a referring facility, and were transferred for same-day PCI were included. Patients' demographics, as well as procedural data and in-hospital outcome, were collected. RESULTS: Three hundred fifty-two participants were included. Of these, 36 (10.2%) patients received transradial access. Patients in the transradial group were older (68 ± 10 vs 62 ± 12 years, P = 0.007), and received a significantly higher total dose of heparin including both, diagnostic and PCI procedures (5935 ± 1865 vs 10029 ± 2771 units, P < 0.001). None of the transradial patients experienced bleeding or access-related complications. In the transfemoral group, 9 (3%) vascular-access complications were recorded. Contrast volume was lower for transradial patients (177 ± 47 vs 216 ± 75 mL, P < 0.001). A higher proportion of outpatients were discharged from the PCI-center the same day after transradial procedures (53% vs 1.3%, P < 0.001). CONCLUSIONS: Transradial access for inter-facility transfer for PCI after diagnostic angiogram appears safe and feasible, without increasing the risk for ischemic hand complications. Transradial access was associated with fewer bleeding and vascular access-site complications, and with a higher likelihood for a same-day discharge home in outpatients.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
