In low-risk patients after acute myocardial infarction, right ventricular function recovers over 6 months and is strongly associated with improvement in interventricular septum motion.
Supports RV monitoring post-MI; leaves open whether IVS-WMSI is a modifiable target.
In low risk patients after AMI, RV function recovered throughout six months of follow up and was already significant at discharge. TAPSE was significantly related to LVEF at 24-48 hours. The magnitude of RV functional recovery was higher in patients with lower initial LVEF. RV functional recovery is best related to IVS-WMSI improvement, suggesting that IVS motion has an important role in RV functional improvement in this setting.
