Assessment of mitral annular velocities by Doppler tissue imaging in predicting left ventricular thrombus formation after first anterior acute myocardial infarction
Introduction: This study was carried out in cardiology department, Zagazig University from August 2005 to December 2006. This study included 60 patients with first acute anterior myocardial infarction. These patients were 36 male (72%) and 14 female (28%). Aim of the work: The aim of this study is t...

This study included 60 patients with first acute anterior myocardial infarction. These patients were 36 male (72%) and 14 female (28%). Aim of the work: The aim of this study is to determine whether early assessment of mitral annular velocities by pulsed wave tissue Doppler imaging predicts left ventricular thrombus formation after first acute anterior myocardial infarction or not. Patients and methods: Patients included in our study represented by first time anterior wall acute myocardial infarction who met the following criteria; chest pain lasting more than 30 min, ST segment elevation greater than 2 mm in two consecutive anterior electrographic leads and transient elevation of biochemical cardiac markers. Patients were excluded if they had evidence of previous anterior myocardial infarction, valvular heart disease, patients with poor Echo window and conduction abnormalities. All patients were subjected to the following: complete history taking, thorough physical examination, laboratory tests, 12-lead surface ECG, determination if the patient was received thrombolytic therapy or not and echocardiographic evaluation (M-mode, two-dimensional and DTI assessment) was performed for all patients within 24 h of arrival to CCU to evaluate LV function and to measure mitral annular velocities then two-dimensional echocardiography to determine thrombus was formed on days 7 and 30. Patients were divided into two groups: group (1); patients with LV thrombus (19 patients “31.6%”) and group (2); patients without LV thrombus (41 patients “68.4%”). Results: There was no significant difference between the two groups as regards age, gender, diabetes mellitus, hypertension, heart rate, peak CPK and whether patients received thrombolytic therapy or not. LVESV and LVEDV were higher in group (1) than in group (2) while EF was lower in group (1) than in group (2). As regards WMSI is higher in group (1) than in group (2). E wave velocity was higher in group (1) than in group (2), while A wave velocity was lower in group (1) than in group (2) and E/A ratio is higher in group (1) than in group (2). Deceleration time of E wave was shorter in group (1) than in group (2) and IVRT were lower in group (1) than in group (2). Em wave velocity was lower in group (1) than in group (2), Am wave velocity had no significant difference between the two groups while Em/Am ratio was lower in group (1) than in group (2) and E/Em ratio was higher in group (1) than in group (2). Sm wave velocity was lower in group (1) than in group (2). From previous data and correlation of TDE finding with other echocardiographic data, we found that systolic and diastolic functions were impaired in patients of group (1) than in group (2) but Sm velocity and WMSI had higher sensitivity and higher specificity (94.7% sensitivity, 95.1% specificity for Sm wave velocity and 94.2% sensitivity, 90.2% specificity for WMSI). Conclusion: From our study, we can conclude that TDE can be used for estimation of systolic and diastolic functions of LV and hence identification of patients at high risk for LV thrombus formation after first time acute anterior myocardial infarction and we recommend more studies to support our results about the importance of the role of oral anticoagulant after AMI.http://www.sciencedirect.com/science/article/pii/S1110260811000408Acute myocardial infarctionLV thrombusTissue Doppler |
