e0315 Explore the relationship between left ventricular mural thrombus and left ventricular aneurysm after acute myocardial infarction

Objective To explore the relationship between left ventricular mural thrombus (LVMT) and left ventricular aneurysm (LVA) after acute myocardial infarction (AMI). Methods The clinical materials of 66 consecutive patients with LVA after AMI were retrospectively analysed. These patients were divided into two groups according the result of LVMT formation diagnosed by echocardiographic. 30 cases with LVMT entered group LVMT and the other 36 cases entered group without LVMT. The mean left atrial (LA), LV end-diastolic and end-systolic diameter, thickness of the interventricular septum (IVS) and LV posterior wall (PW), and the size of the aneurysm as well as the LV ejection fraction (LVEF) were compared among two groups. Results According to results of analysis, the mean LA, LV end-diastolic and end-systolic diameter, PW thickness, and the size of the aneurysm did not differ between patients with and without LVMT. The thickness of the IVS were greater in patients in with LVMT than in those without LVMT (1.17±0.26 vs 1.04±0.19 cm, respectively; p=0.02). Conclusions Left ventricular aneurysm formation after AMI could be related to LVMT. However, the size of the aneurysm was not significant associated with LVMT.
