Does a machine learning model utilizing unstructured admission records improve MACE prediction compared to GRACE and TIMI scores in patients with ACS?
Effect estimate: AUC 72%
Machine learning models utilizing unstructured admission records can effectively predict MACE in ACS patients early in their hospitalization, outperforming traditional GRACE and TIMI risk scores.
Hu et al. (2016) conducted an observational in Acute coronary syndrome (n=2,930). Machine learning models using admission records vs. GRACE and TIMI risk scores was evaluated on MACE prediction (AUC 72%). A machine learning model utilizing unstructured admission records achieved an AUC of 72% for MACE prediction in ACS patients, outperforming GRACE and TIMI risk scores.
