Missed myocardial infarctions in ED patients prospectively categorized as low risk by established risk scores

Using their recommended cutpoints and non high sensitivity cTn, TIMI and unstructured clinical impression were the only scores with no missed cases of AMI. Using lower cutpoints (GRACE ≤ 48, TIMI = 0, EDACS ≤ 11, HEART ≤ 2) missed no case of AMI, but classified less patients as low-risk.
