Moderate risk. However, further testing is indicated, with a stress test (with or without myocardial imaging), in patients whose risk of CAD is 5% to 70%, based on the Diamond Forrester classification or an intermediate Marburg Heart Score (ie, a score of 2 or 3 but a normal EKG). This further testing can be performed urgently in patients who have multiple other risk factors that are not assessed by the Marburg Heart Score.

High risk. In patients whose risk is > 70%, invasive testing with angiography should be considered.35,49

EKG abnormalities. Patients with a Marburg Score of 2 or 3 and an abnormal EKG should be sent to the ED (FIGURE). There, patients with a HEART score < 4 and a negative 2-3–hour troponin test have a < 1% chance of ACS and can be safely discharged.31
