Delayed contrast-enhanced magnetic resonance imaging for the prediction of regional functional improvement after acute myocardial infarction

Abstract: In patients with recent reperfused MI, functional improvement of stunned myocardium is predicted by DCE-MRI.

“…[13][14][15] Since, DE-MRI showed no hyper-enhancement of the myocardium, it can be predicted that on follow-up complete reversal of the morphological abnormalities should be observed, as was seen in our case (Figure 3). …”

“…Importantly, the presence of severely delayed microvascular reperfusion was predictive of impaired LV systolic function independently of the transmurality of infarction. Although the transmural extent of myocardial scarring in AMI identified by CMR is a strong predictor of reduced recovery of wall motion, 14,15 our data suggest that acutely (within 24 hours of reperfusion), the dynamics of microvascular reperfusion characterized by CMR perfusion identify an area of myocardium surrounding the scarred tissue, which, although viable, may have severely impaired microvascular flow. Such an ischemic "penumbra" may be at risk in the ensuing days of further cell death 16 or triggering conversion to hibernation over a longer period.…”

“…За время наблюдения у 3 из 54 больных с признаками нежизнеспособного миокарда зарегистрирована коронарная смерть. Ремоделирование ЛЖ опре-делялось у 22 (43,1 %) из 51 больного с призна-ками нежизнеспособного миокарда, среднее количество сегментов с признаками нежизне-способного миокарда у этих больных составило 4,0 [4,[5][6]0], что согласуется с данными Sato A и соав. [18].…”

“…Через 12 месяцев в группе с 1 типом контрастирования наблюдалось значительное увеличение ФВ ЛЖ по сравнению с ис-ходными данными (63,4 ± 7,6% и 56,3 ± 6,6%, p<0,001), а в группах со 2 и 3 типами до-стоверной динамики ФВ ЛЖ не определялось. Через 12 месяцев постинфарктное ремо-делирование ЛЖ было зарегистрировано у 22 из 51 больного (43,1%) с признаками не-жизнеспособного миокарда (2 и 3 типы), среднее количество сегментов с признаками нежизнеспособного миокарда у этих больных составило 4,0 [4,[5][6]0].Выводы. КТ является надежным методом оценки жизнеспособности миокарда у больных ОИМ.…”
