Peak subepicardial twist was strongly related to infarct size ( number of segments with transmural scar : r ( @ ) = @ , P < @ ; total scar score : r ( @ ) = @ , P < @ ) compared with peak subendocardial twist ( number of segments with transmural scar : r ( @ ) = @ , P < @ ; total scar score : r ( @ ) = @ , P < @ ) .
