Clinical outcomes after acute myocardial infarction according to a novel stratification system linked to a rehabilitation program

The lengths of hospital stay and CCU stay were significantly shortest in the L-risk group, followed by the I-risk group, and longest in the H-risk group. MACE were most frequently observed in the H-risk group, followed by the I-risk group, and least in the L-risk group. These results support the validity of our new classification system.
