REDUCTION OF LEFT VENTRICULAR DILATATION BEYOND THE FIRST YEAR FOLLOWING ANTERIOR MYOCARDIAL INFARCTION.

•Reduction of left ventricular dilation (RD) beyond 1year after STEMI is unknown.•Perfusion gated-SPECT at 1 and 3 years was evaluated in 168 3-year STEMI survivors.•RD occurred in 21%, stationary dilation in 50%, and progressive dilation in 29%.•RD developed in patients with frank as well as those with little or moderate dilation at 1 year.•These findings possibly suggest very late changes in infarct size.
