Abstract
Objective To evaluate the effect of strain rate imaging in quantitative detection of regional myocardial function in patients with acute myocardial infarction after primary or delayed percutaneous coronary intervention (PCI).Methods Totally 30 patients with acute myocardial infarction with ST-segment elevation were divided as the primary and delayed treatment groups.The peak strain rates (SR) at systolic,early and late diastolic phases were detected before PCI operation and one week,1 month and 3 months after PCI.Results In the primary PCI group the systolic SR,early diastolic SR and late diastolic SR at 1 month and 3 months after the PCI operation increased significantly as compared with those before PCI (P0.01).In the delayed PCI group,only early diastolic SR at 3 months after PCI increased significantly as compared with that before PCI (P0.05).Conclusion Strain rate imaging can quantitatively evaluate the regional myocardial function in acute myocardial infarction with ST-segment elevation after primary or delayed PCI.
