Abstract
The predictive value of four-dimensional speckle tracking imaging (4D-STI) risk classification and TIMI risk scores for the prognosis of patients with ST-segment elevation myocardial infarction (STEMI) after reperfusion therapy were investigated. One hundred and twenty patients with STEMI after reperfusion therapy were involved. At 12 h after reperfusion therapy, 2nd and 3rd day, the three-dimensional longitudinal strain (LS), circumferential strain (CS) and radial strain (RS), area strain (AS), as well as other 4D-STI detection indicators, were collected. The patients were followed up for one year, and were divided into good prognosis group and poor prognosis group. LS, CS, RS and AS indicators were analyzed between these two groups. The ROC curve was drawn to establish the 4D-STI risk classification and its predictive value for poor prognosis and mortality were compared with TIMI risk scores. AS, LS and RS at 12 h after reperfusion treatment, and AS and RS at 2nd and 3rd day had a certain degree of prediction accuracy in STEMI patients in the poor prognosis group. In the 4D-STI and TIMI risk scores, the risk of death and adverse prognosis significantly increased as the risk scores increased (P<0.01). The 4D-STI risk score for predicting poor prognosis and mortality was greater than the TIMI risk score. 4D-STI risk scores are superior to TIMI risk scores in predicting poor prognosis and mortality in patients with STEMI after reperfusion therapy.
