Background: Ischemic heart disease is nowadays the leading cause of morbidity and mortality in the western world. Accurate detection and evaluation of this disease are of major importance. Cardiac magnetic resonance imaging (CMR) has an increasing role in the detection and evaluation of ischemic heart disease, and can be used to measure global and regional myocardial function, the presence of ischemia and myocardial scar tissue. Aim of Study:The primary aim of this study is to compare the CMR with the Echocardiography (Echo) in evaluating occurrence of micro vascular obstruction and major adverse cardiac events within one month of revascularization. Material and Methods:The study was carried out at the National Heart Institutes during the period from 1 st of October 2016 till 1 st of October 2017. Twenty patients were included in the study with documented ST segment elevation myocardial infarction (STEMI) and underwent reperfusion with primary percutaneous coronary intervention (PCI).All patients are subjected to history, laboratory investigation, Electrocardiogram (ECG), ECHO, revascularization by primary PCI, CMR and another Echo after revascularization.Results: There was highly statistically significant relation between patients with Microvascular obstruction (MVO) and occurrence of major advance cardiac events (MACE) as all patients with MVO had MACE (p-value <0.001), while only 6% of the patients without MVO had MACE. After revascularization, 4 patients had MVO (20% of the study population), while MACE occurred in 5 patients (25% of the study population). There were statistically significant relation between score index (SI) and Ejection Fraction (EF) before and after revascularization (p-value <0.001) with mean score index before 1.27-}0. 15 and after 1. 13-}0.09 while mean EF before 52.80-}5.55 and after 57.80-}4.46.Correspondence to: Dr. Mohamed A. Hassan, E-Mail: Dr_Mohamed_Abdalla@outlook.com After revascularization there were significant difference between score index by ECHO and that by CMR (p-value= 0.035) while no significant difference measured between EF by ECHO and that by CMR.Before revascularization only EF has significant correlation with MVO, patients without MVO had mean 54.25-}4.68 and patients with MVO had mean 47-}5.41 with p-value=0.029 while no significant relation between score index, left ventricle end systolic diameter ( LVESD), and left ventricle end diastolic diameter (LVEDD) with MVO with p-value >0.05. As regarding occurrence of MVO and ECHO there were significant difference in score index between patients with MVO and patients without MVO (p-value<0.05) Also, EF has significant difference between patients with MVO and patients without MVO (p-value <0.05).After revascularization score index by ECHO has significant relation in prediction of MVO (p-value=0.019). Also, score index by CMR has highly significant relation in prediction of MVO (p-value <0.001). Conclusion:We conclude that data obtained by CMR are better than ECHO in assessment of MVO and MACE.

“…These results are controversial with result by Li et al, [15] in their study. where fifty six patients with AMI with elective treatment by PCI were included, they found that the difference was of no statistical significance in the comparison of ECHO evaluation in LVEDD, LVESD, and LVEF prior to and following PCI.…”

“…The predictive ability of CMR in myocardial infarction (MI) is constantly being explored. At present, some studies have confirmed its role in AMI and other special types of myocardial infarction, such as unrecognized myocardial infarction (UMI) and myocardial infarction with nonobstructed coronaries (MINOCA) [ 63 , 64 , 65 , 66 ]. Recently, the CMR risk score was proposed for risk categorization in STEMI patients.…”

Acute coronary syndrome (ACS) has a high incidence of adverse cardiovascular events, even after early invasive treatment. Patients may still have a poor prognosis after discharge. The keys to the long-term survival of patients with ACS include effective treatment in a timely manner and identification of those patients who are at higher risk for long-term adverse events. Therefore, several nations have now devised a range of risk assessment models to provide data for accurately formulating treatment plans for patients with various risk levels following an ACS to prevent short and long-term cardiovascular events. The purpose of this article is to review the risk scores associated with mortality and ischemic events in patients with ACS. By using the clinical risk prediction score, we can accurately and effectively judge the prognosis of patients, so as to take a more reasonable treatment.

Objectives To compare the repeatability and interrelation of various late gadolinium enhancement (LGE) assessment techniques for monitoring fibrotic changes in myocarditis follow-up. Materials and methods LGE extent change between baseline and 3-month cardiovascular magnetic resonance (CMR) was compared in patients with acute myocarditis using the full width at half maximum (FWHM), gray-scale thresholds at 5 and 6 standard deviations (SD5 and SD6), visual assessment with threshold (VAT) and full manual (FM) techniques. In addition, visual presence score (VPS), visual transmurality score (VTS), and a simplified visual change score (VCS) were assessed. Intraclass-correlation (ICC) was used to evaluate repeatability, and methods were compared using Spearman’s correlation. Results Forty-seven patients (38 male, median age: 27 [IQR: 21; 38] years) were included. LGE extent change differed among quantitative techniques (p < 0.01), with variability in the proportion of patients showing LGE change during follow-up (FWHM: 62%, SD5: 74%, SD6: 66%, VAT: 43%, FM: 60%, VPS: 53%, VTS: 77%, VCS: 89%). Repeatability was highest with FWHM (ICC: 0.97) and lowest with SD5 (ICC: 0.89). Semiquantitative scoring had slightly lower values (VPS ICC: 0.81; VTS ICC: 0.71). VCS repeatability was excellent (ICC: 0.93). VPS and VTS correlated with quantitative techniques, while VCS was positively associated with VPS, VTS, VAT, and FM, but not with FWHM, SD5, and SD6. Conclusion FWHM offers the least observer-dependent LGE follow-up after myocarditis. VPS, VTS, and VCS are practical alternatives, showing reliable correlations with quantitative methods. Classification of patients exhibiting either stable or changing LGE relies on the assessment technique. Clinical relevance statement This study shows that LGE monitoring in myocarditis is technique-dependent; the FWHM method yields the most consistent fibrotic tracking results, with scoring-based techniques as reliable alternatives. Key Points Recognition of fibrotic changes during myocarditis follow-up is significantly influenced by the choice of the quantification technique employed. The FWHM technique ensures highly repeatable tracking of myocarditis-related LGE changes. Segment-based visual scoring and the simplified visual change score offer practical, reproducible alternatives in resource-limited settings.
