MATRIX: Radial vs. Femoral Trial design: Subjects with acute coronary syndromes were randomized to radial access (n = 4,197) vs. femoral access (n = 4,207). Results (p = 0.031) Death, MI, or stroke: 8.8% of the radial group vs. 10.3% of the femoral group (p = 0.031; this exceeded the prespecified α level of 2.5%) Death, MI, stroke, or BARC (type 3 or 5) major bleeding: 9.8% vs. 11.7% (p = 0.0092), respectively, for radial vs. femoral 10.3 % 8.8 Conclusions Among patients with acute coronary syndromes, radial access was not associated with a reduction in major adverse cardiovascular events However, radial access was associated with a reduction in net adverse events, including major bleeding Radial access Femoral access Valgimigli M, et al.
