Abstract

AbstractBackground: Subtle changes in left ventricular wall motionpatterns have diagnostic and prognostic values in patientswith Coronary Artery Disease (CAD).Aim of Study: The aim of this studywasto highlightthediagnostic role of Cardiac Magnetic Resonance imaging (CMR) in assessment of the myocardial wall motion abnor-malities in Myocardial Infarction (MI) patients.Material and Methods: This retrospective research wasperformed in 50 patients classified into two groups: Group 1(25 patients with Acute Myocardial Infarction (AMI) (23males and 2 females) and group 2 (25 patients with ChronicMyocardial Infarction (CMI) (22 males and 3 females). Bothclasses were diagnosed based on medical, echocardiography,and other approaches of cardiologist investigation. The meanage was 52.16±6.884 years for group 1 and 51.04±12.341years in group 2. All patients underwent CMR evaluationusing Cine Steady State Free Precession (SSFP) in short axisand 4 chamber views.Results: Hypokinesia was the most commonly observedwall motion abnormality among the study groups. It was seen in 13 (52%) patients in group 1 and the same in group 2. Akinesia was seen in 12 (48%) patients in group 1 and 10(48%) patients in group 2 and dyskinesia was observed in 2 (8%) patients in group 2 and not observed in group 1.Conclusion: Identification of wall motion abnormalitiesin MI patients may help to identify higher risk patients thatwould benefit from an earlier invasive strategy. We concludethat CMR detected the wall motion abnormality precisely andshould be added to the routine investigation of MI patientsfor better evaluation and assessment.
