Patients <1 year after onset of MI had much more impaired global and free wall RV PSS than those ≥1 year after onset of MI among the 3 groups (global RV PSS: -21 ± 6% in patients <1 year, -17 ± 6*% in patients ≥1 year, and −18 ± 6% in patients with unknown duration, and free wall RV PSS: -25 ± 7% in patients <1 year, -20 ± 8*% in patients >1year, and −22 ± 7% in patients with unknown duration *p<0.05 vs. patients <1 year) although age, gender, log-transformed plasma BNP, and longitudinal LV PSS in the 4-chamber view were similar. Here, NPPB is linked to myocardial infarction.
