Abstract
Objective: To investigate the change of global and regional left ventricular systolic function after aspiration thrombectomy in percutaneous coronary intervention(PCI) or single PCI for patients with acute myocardial infarction by real-time three-dimensional echocardiography(RT-3DE). Methods: Fifty-five subjects with acute myocardial infarction were studied by RT-3DE. And they were divided into two groups with aspiration thrombectomy or without PCI. Then respectively compared the global and regional diastolic volumes(EDV, rEDV), the global and systolic volumes(ESV, rESV), the global and ejections fractions(EF, rEF) between the two groups after 1 week and 6 months of PCI, and observed the thrombolysis in myocardial infarction trial(TIMI) and ST segment resolution of electrocardiogram(STR). Results: Compared with single PCI, TIMI grade 3 and STR≥50% was better in patients with aspiration thrombectomy. And the EDV, rEDV, ESV, rESV by RT-3DE of patients with single PCI at the six months were larger than that with aspiration thrombectomy in PCI(P<0.05), while EF, rEF was lower(P<0.05). And the △EDV, △EF of all the patients at the six months had positive correlation with STR. Conclusion: Aspiration thrombectomy in PCI with AMI were more conductive to recover of the left ventricular function by RT-3DE. And △EDV, △EF by RT-3DE and STR can predict clinical prognosis more accurately for AMI with PCI.
