## Radial vs. Femoral Access in ACS: The Evidence
* Analysis of Percutaneous Coronary Intervention (PCI) outcomes based on access site.
* Evaluation of mortality and bleeding risks in Acute Coronary Syndrome patients.

## Seminal Evidence: Key Randomized Clinical Trials
* **RIVAL (2011):** Neutral overall, but showed benefit in STEMI subgroups and high-volume radial centers.
* **RIFLE-STEACS (2012):** STEMI study showing significantly lower cardiac mortality with radial access (5.2% vs. 5.9% femoral).
* **MATRIX (2015):** Reduced MACE and major bleeding; all-cause mortality benefit driven by bleeding reduction.

## Statistical Outcomes: Mortality & Bleeding
* **Mortality:** Odds Ratio of 0.72 for radial access based on meta-analysis.
* **Bleeding:** Odds Ratio of 0.57, reflecting a significant reduction in access-site complications.
* **Key Mechanism:** Reduction in major bleeding directly correlates with improved survival outcomes.

## Implications for Practice & Patient Experience
* **Early Mobilization:** Radial patients can mobilize immediately versus 4-6 hours of bed rest for femoral patients.
* **Patient Comfort:** Reduction in back pain and discomfort associated with supine positioning.
* **Economic Impact:** Shorter hospital stays and reduced ICU days due to fewer complications.
