Classification and Regression Tree for Prediction of ASCVD Patients at Very High Risk: Recent ACS, ischemic stroke, hypertension, PAD, history of MI, and age were identified as the most important predictors of VHR status. Percentage of patients classified as VHR and sample sizes are given below the bars.

ASCVD = atherosclerotic cardiovascular disease, ACS = acute coronary syndrome, MI = myocardial infarction, NVHR = not very high-risk, PAD = peripheral arterial disease, VHR = very high-risk.
