Annualized event rates of MACE stratified by age, presence/absence and the amount of myocardial ischemia. Annualized event rates of MACE are stratified by presence/absence of myocardial ischemia (a) and the amount of myocardial ischemia (b) in different age categories: < 50 years; 50–60 years; 60–70 years and > 70 years. Mild, moderate, and severe myocardial ischemia were defined as the involvement of 1–2, 3–5, and ≥ 6 myocardial segments, respectively
