Role of Cardiac Magnetic Resonance (CMR) Imaging inthe Assessment of Wall Motion Abnormalities in MyocardialInfarction Patients

Abstract

Background: Subtle changes in left ventricular wall motion patterns have diagnostic and prognostic values in patients with Coronary Artery Disease (CAD). Aim of Study: The aim of this studywasto highlightthe diagnostic role of Cardiac Magnetic Resonance imaging ( CMR) in assessment of the myocardial wall motion abnormalities in Myocardial Infarction (MI) patients. Material and Methods: This retrospective research was performed in 50 patients classified into two groups: Group 1 (25 patients with Acute Myocardial Infarction (AMI) (23 males and 2 females) and group 2 (25 patients with Chronic Myocardial Infarction (CMI) (22 males and 3 females). Both classes were diagnosed based on medical, echocardiography, and other approaches of cardiologist investigation. The mean age was 52.16±6.884 years for group 1 and 51.04±12.341 years in group 2. All patients underwent CMR evaluation using Cine Steady State Free Precession (SSFP) in short axis and 4 chamber views.Results: Hypokinesia was the most commonly observed wall 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 abnormalities in MI patients may help to identify higher risk patients that would benefit from an earlier invasive strategy. We conclude that CMR detected the wall motion abnormality precisely and should be added to the routine investigation of MI patients for better evaluation and assessment.
