Aim The aim of the study was to evaluate the left ventricle ( LV ) function with speckle tracking echocardiography ( STE ) and to assess its relation to prognosis in patients after acute myocardial infarction ( AMI ). Methods Sixty‐three patients (F/M = 16/47 pts; 62.33 ± 11.85 years old) with AMI ( NSTEMI / STEMI 24/39 pts) and successful percutaneous coronary intervention ( PCI ) with stent implantation (thrombolysis in myocardial infarction; TIMI 3 flow) were enrolled in this study. All patients underwent baseline two‐dimensional conventional echocardiography and STE 3 days (baseline) and 30 days after PCI . All patients were followed up for cardiovascular clinical endpoints, major adverse cardiovascular endpoint ( MACE ), and functional status (Canadian Cardiovascular Society and New York Heart Association). Results During the follow‐up (31.9 ± 5.1 months), there were 3 cardiovascular deaths, 15 patients had AMI, 2 patients had cerebral infarction, 24 patients reached the MACE. Baseline LV torsion (P = 0.035), but none of the other strain parameters were associated with the time to first unplanned cardiovascular hospitalization. Univariate analysis showed that baseline longitudinal two‐chamber and four‐chamber strain ( sL a2 0 and sL a4 0) and the same parameters obtained 30 days after the AMI together with transverse four‐chamber strain ( sL a2 30, sL a4 30, and sT a4 30) were significantly associated with combined endpoint (MACE). The strongest association in the univariate analysis was found for the baseline sL a2. However, in multivariable analysis only a left ventricular remodeling (LVR – 27% pts) was significantly associated with MACE and strain parameters were not associated with the combined endpoint. Conclusion The assessment of LV function with STE may improve cardiovascular risk prediction in postmyocardial infarction patients.
