Cardiovascular Magnetic Resonance Imaging for Suspected Ischemic Heart Patients in Assessment of Microvascular Obstruction and Intramyocardial Hemorrhage

Background: Myocardial infarction (MI) is a prominent reason for fatality and disability globally. Therefore, a precise diagnosis of MI is crucial as it guides the clinical treatment. Aim: To determine if unique characteristics revealed by Cardiac MRI can allow radiologists to assess the MVO and IMH. Patients and methods: This cross-sectional research has been performed on 30 cases with suspected ischemic heart disease who underwent Cardiovascular magnetic resonance imaging in the radiology department at Al-Zahraa Hospital throughout the period from March 2023 to March 2024. Results: A statistically higher significant variance was observed in mean LGE size, LGE%, MVO size, MVO%, and IMH size between MVO (+) and IMH (+) groups p0.05. The mean LGE size was 44.84±14.82, while the mean MVO size was 9.17±3.20. The mean IMH size was 12.37±5.03, but no significant difference was found in LVEF p>0.05. A significant positive association was observed among MVO size, IMH size, and LGE size, with R-values of 0.695 and 0.762, respectively, and p Conclusion: Cardiac MRI aids in understanding pathophysiologic features in acute chest pain patients, especially those with MVO, and can provide precise risk stratification, identify causes requiring different treatment, assess risk areas, detect MVO, and define viable myocardium.
