The possible association of increased @entity1002 ( @entity1002 ) in @entity1 with increased serum @entity141 was observed in our clinic. Six @entity1 with confirmed @entity459 and hypercalcaemia were studied prospectively. Tc-99m sestamibi gated SPECT was done pre- and postoperatively. The @entity1002 was abnormally high in all the @entity1 pre-operatively, i.e. above the normal reference range (47-61%) as used in our clinic. It decreased in all of them postoperatively, yet in only three @entity1 to values within the normal range. This was associated with normalisation of the serum @entity141 values. The median of the pre-operative @entity1002 was 74% and postoperative it was 61.5%. The median difference was 9% with a 95% CI for the median difference for paired data (6; 26). This was statistically significant. Increased @entity1002 was not previously described as part of the clinical picture of @entity459 . The in vivo effect of chronic hypercalcaemia on LV pump function my need to be revisited.
