if preserved hearts were divided into two groups based on coronary vascular resistance measured at the end of the preservation period lower than 18 mmhg.min per ml ( group 1 ) , and higher than or equal to 18 mmhg.min per ml ( group 2 ) , it appeared that the haemodynamic function of group 2 hearts was about half that of group 1 hearts .
