Left Ventricular Thrombus Formation in Acute Anterior Wall Myocardial Infarction: A Comparison Between Thrombolyzed and Non-Thrombolyzed Patients.

Introduction Left ventricular thrombus (LVT) formation is a prominent complication of acute myocardial infarction (AMI). Accurate and prompt detection of the condition is important as it poses a high risk for thromboembolic events that can be arrested by systemic anticoagulation. The purpose of our study was to evaluate the frequency of LVT formation in thrombolyzed and non-thrombolyzed patients with AMI to ascertain the current magnitude of the problem in the local population. Methods The study was conducted at the Chaudhry Pervaiz Elahi Institute of Cardiology in Multan, Pakistan. A total of 281 patients of either gender aged between 30-65 years with anterior wall myocardial infarction (AWMI; both thrombolyzed and non-thrombolyzed) were included in the study. Once they were enrolled in the study, all the relevant baseline investigations were performed. A detailed history was taken and examinations were done; serial ECG and echocardiography were performed till discharge from the hospital on the third day of hospitalization to record the final outcome of the study, i.e., LVT formation. Results The mean age of the patients was 55.54 ± 7.26 years. Overall, LVT formation was noted in 65 cases (23.1%), of which 11 (16.9%) were thrombolyzed patients and 54 (83.1.1%) were non-thrombolyzed. A significant association of LVT was noted with age, hypertension, family history, and duration of symptoms. Conclusion We found a high frequency of LVT formation among patients with AWMI who have not undergone thrombolytic therapy. It was observed that LVT was notably associated with advanced age, hypertension, and other comorbidities. Early presentation to the hospital and thrombolysis reduce the risk of developing LVT, which in turn can reduce morbidity and mortality in such patients.
