ACUTE ANTERIOR MYOCARDIAL INFARCTION

THE INCIDENCE OF LEFT VENTRICULAR THROMBUS

Abstract

Objectives: The study was designed to see the incidence of left
ventricular thrombus in first episode of acute MI. Material & Methods: This study was carried in patients
admitted in Coronary Care Unit of Allied Hospital Faisalabad. Total No of patients were 30 and patients
included in the study were who have first Q wave acute MI and ECG changes of ST elevation of > Imm in two
contiguous lead. This diagnosis of left ventricular thrombus was made by echocardiography which was done
6 days after the admission. Results: A total of 30 patients with first episode of acute anterior wall MI were
studied, 24(70%) were males and 6(30%) were females. The mean age of males was 51.79±13.86 and that of
females was 54.83±10.15 years. On echocardiography, 8 patients had LVT, 6(75%) were males and 2(25%) were
females. On admission 16(53.33%) patients were thrombolised with streptokinase. Two of them developed
LVT. While others did not. Among LVT remaining 14(42.70%) patients, 6 were found to have LVT on the 6th
day of admission. Conclusion: The study has revealed that the incidence of LVT after acute anterior MI in one
population in quite significant. The increasing use of thrombolytic therapy in our setting may have favourable
outcome. Patients older than 50 years of age may be at increased risk of post infarct LVT.
