Clinical outcomes and arrhythmic events in the 3 groups of patients, stratified according to the time elapsed from last MI
Time from MI > 40 days and < 1,5 years Time from MI ≥ 1,5 years and < 7 years Time from MI ≥ 7 years
N = 158 N = 171 N = 314
Follow-Up, months
Median (IQR) 24 (15, 35) 22 (12, 34) 22 (11, 32)
Detection of at least 1 ventricular tachyarrhythmia (% ) § 33 (20.9%) 45 (26.3%) 104 (33.1%)
Delivery of at least 1 appropriate device therapy (ATP or shock) (%) § 27 (17.1%) 34 (19.9%) 82 (26.1%)
All cause mortality (%) 17 (10.8%) 19 (11.1%) 38 (12.1)
Cardiac mortality (%) 9 (5.7%) 8 (4.7%) 20 (6.4%)
SCD mortality (%) 3 (1.9% ) 3 (1.8%) 9 (2.9%)

§ Significant difference between strata, p < 0,05.
