Left ventricular thrombus and myocardial infarction.
The aim of our study was to determine whether a relationship existed between echocardiographic evidence of left ventricular thrombus (LVT) and clinical course of myocardial infarction. We followed 143 patients who had had typical myocardial transmural infarction (82 with "anterior") and 61 with "inferior" myocardial infarction) over a three month period. Incidence of LVT, detected by Two-Dimensional Echocardiography (TDE) was significantly greater in subjects affected by "anterior" myocardial infarction (p less than 0.05). Furthermore, the occurrence of LVT was more frequent in the presence of left ventricular a-, dys-kinesis detected by TDE (p less than 0.01). No significant relationship was demonstrated either with the occurrence of severe ventricular arrhythmias (Lown 3-4-5) or with an abnormal stressing test performance. Thus certain clinical and laboratory features such as anterior site of infarction, higher serum level of CPK and CPK-MB and severe alterations of left ventricular kinesis proved to be useful in identifying a subset of patients most likely to have LVT who may benefit from early anticoagulant therapy.
