Brief Summary:
Left myocardial infarction (MI), has a negative impact of long term morbidity and mortality. Even in patients treated successfully by angioplasty in the acute phase of infarct, the remodelling is observed in approximately 30% of cases. It is important to predict the occurrence of this phenomenon in the early phase after MI for the selection of patients who could eventually benefit from new therapeutic approach as for example cell replacement therapy. It has been advocated that stem cells coronary injections should be performed between the 5th and 10th day after an acute event. We hypothesise that a low dose dobutamine gated Tc-99m-mibi SPECT performed on 5th-6th day after reperfused acute MI can predict left ventricular remodelling and serve as a method to screen patients who could benefit from cell replacement therapy.
Detailed Description:
All patients will be evaluated by ce-MRI during the initial hospital stay (5th - 6th day) and at 6-month follow-up. Left ventricular remodelling will be defined as an end-diastolic volume increase of \>20% between the two exams. A low dose dobutamine gated Tc-99m-mibi SPECT will be also performed on 5th-6th day. Differences in the infarct size and severity as well as the residual inotrope reserve in the infarct area are expected between groups with and without remodelling.
