Motivation: Early prediction of LVr is significant for the selection of clinical treatment to improve the prognosis of STEMI patients.
Goal(s): To explore whether strain markers, as derived by CMR feature tracking (CMR-FT) at the early onset of STEMI may improve the predictive certainty of LVr.
Approach: 120 patients with a first reperfused STEMI were investigated prospectively within 7 days after PCI. Both LA and LV strain and strain rate were calculated using CMR-FT.
Results: The reduction of LV-GLS can predict LVr independent of T2* value, and the reduction of LA-ℇe remain an independent predictor of LVr after adjusting LV-GLS and T2* value.
Impact: In the present study, the reduction of LA conduit strain derived by CMR-FT at the early onset of STEMI increases the likelihood of LVr independent of T2* value and LV-GLS.
