FREQUENCY OF LEFT VENTRICULAR THROMBUS FORMATION AFTER ACUTE ANTERIOR WALL ST ELEVATION MYOCARDIAL INFARCTION

Objective: To determine the frequency of left ventricular thrombus (LVT) formation after Acute Anterior wall ST Elevation Myocardial Infarction (STEMI). Methodology: This descriptive study was conducted at CCU department, Bahawal Victoria Hospital, Bahawalpur from January 15, 2012 to July 14, 2012. Patients age between 20 to 70 years and of any gender with diagnosis of acute anterior wall STEMI admitted through emergency department within 12 hours of chest pain were enrolled. Patients were treated according to standard ward th protocol. Echocardiography was performed at 4 day of admission to diagnose for left ventricular thrombus. Results: A total of 195 patients were studied. There were 146(74.9 %%) males and 49(25.1%) females. Mean age of patients with LVT was 55.43 +/- 7 and those without LVT were 52.48 +/- 10.2. On echocardiographic examination,30(15.4%) patients had LVT, out of these 22(73.3%) were males and 8(26.7%) were females in total. Among 116 (59.5%) patients thrombolysed, 6 (502%) patients developed LVT while 79 (40.5%) patients who were not thrombolysed 24(30.4%) developed LVT (p value<0.001). Conclusion: The frequency of LVT is common in patients presenting with acute anterior STEMI particularly those patients who are not thrombolysed. out of these 22(73.3%) were males and 8(26.7%) were females in total. Among 116 (59.5%) patients thrombolysed, 6 patients developed LVT while 79 patients who were not thrombolysed.
