ABSTRACT
ObjectiveTo investigate the correlation between recent cardiac events and the score of myocardial infarction by delayed-enhancement MRI (DE-MRI).Methods DE-MRI was performed in 40 subjects with coronary artery disease.The score of myocardial infarction by DE-MRI,the ejection fraction (EF) by echocardiography,recent cardiac events (the number of weekly nitroglycerin,the number of weekly angina episodes and the onset number of heart failure in the last year),6-minute walking distance,as well as the Seattle angina questionnaire (SAQ) score were assessed.The Spearman correlation test and Kruskal-Wallis test,Mann-Whitney test were used for the statistics.ResultsThere were negative correlation between the myocardial infarction score by DE-MRI (median 12,inter-quartile range6.0-19.8) and the 6-minute walking distance(378.93 ± 100.53 ),SAQ score (74.55 ± 11.40 ) (r was 0.66 and 0.54,P <0.05).The myocardial infarction score by DE-MRI was strongly correlated with the number of weekly nitroglycerin ( median 1 ; inter-quartile range0-2.8),the number of weekly angina episodes ( median 3,inter-quartile range1-6.5 ) and the onset number of heart failure in the last year ( median 0,inter-quartile range0-2) (r was 0.87,0.85 and 0.89,P <0.05).EF [(49.2 ± 13.72)%] was negative correlation with the number of weekly nitroglycerin,the number of weekly angina episodes and the onset number of heart failure in the last year (r were 0.67,0.73 and 0.73,P <0.05).ConclusionDE-MRI can be used for evaluation and prediction of future cardiac events.
