Abstract Objective: To compare the change of left ventricular regional systolic function of patients with cardiogenic shock(CS) complicating acute myocardial infarction(AMI) before and after IABP with speckle tracking imaging technique, and to discuss the value of speckle tracking imaging(STI) in the therapy of intra-aortic balloon pump counterpulsation(IABP). Methods: Thirty-four patients with CS complicating AMI underwent IABP, STI was used to detect the systolic strain parameters of infarction: peak longitudinal, radial, circumferential strain(LSpeak, RSpeak, CSpeak) and the time to peak strain(TPSLS, TPSRS, TPSCS). A comparative analysis was done between before and after IABP. Results: After IABP, LSpeak, RSpeak, CSpeak increased in each infarct stage and TPSLS, TPSRS, TPSCS decreased(all P＜0.05). Conclusion: STI can accurately evaluate the change of left ventricular regional systolic function of patients with CS complicating AMI before and after IABP.
