BACKGROUND: A risk classification of acute myocardial infarction (AMI) linked to a rehabilitation program has not been established.
METHODS: We allocated 292 patients with AMI into the low- (L) (n=108), intermediate- (I) (n=72), and high- (H) (n=112) risk groups according to our original risk classification. The primary endpoint was major adverse cardiac events (MACE), defined as the composite of cardiac death, non-fatal AMI, stent thrombosis, and ischemia-driven target vessel revascularization. The mean follow-up period was 252 days.
RESULTS: The length of coronary care unit (CCU) stay and hospital stay was shortest in the L-risk group (CCU stay, 1.0±1.0 days; hospital stay, 5.6±3.2 days), followed by the I-risk group (CCU stay, 2.3±1.8 days; hospital stay, 8.1±2.7 days), and longest in the H-risk group (CCU stay, 5.1±5.0 days; hospital stay, 14.6±12.6 days) (p<0.001). MACE were most frequently observed in the H-risk group (26.8%), followed by the I-risk group (5.6%), and least in the L-risk group (1.9%) (p<0.001).
CONCLUSIONS: 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.
