Prediction of radial crossover in acute coronary syndromes: derivation and validation of the MATRIX score.

ABSTRACT:

Background

The radial artery is recommended by international guidelines as the default vascular access in patients with acute coronary syndromes (ACS) managed invasively. However, crossover from radial to femoral access is required in 4-10% of cases and has been associated with worse outcomes. No standardised algorithm exists to predict the risk of radial crossover.

Aims

We sought to derive and externally validate a risk score to predict radial crossover in patients with ACS managed invasively.

Methods

The derivation cohort consisted of 4,197 patients with ACS undergoing invasive management via the randomly allocated radial access from the MATRIX trial. Using logistic regression, we selected predictors of radial crossover and developed a numerical risk score. External
