Text: In contrast, grade 3 patients, compared with grades 0-2 patients, showed 1) a greater global ejection fraction at 1 week (54 % versus 49 %, p = 0. 006) and at 1 month (54 % versus 49 %, p = 0. 01), 2) a greater infarct zone ejection fraction at 1 week (41 % versus 33 %, p = 0. 003) and at 1 month (42 % versus 32 %, p = 0. 003), 3) smaller enzyme peaks, significant for lactate dehydrogenase, and shorter times to enzyme peaks, significant for all four enzymes, 4) a smaller QRS score at discharge and at 1 month, and 5) a trend toward a lower morbidity index.
