[Is it practical to assess the functional state of the heart based on the shape of the Starling curves in intensive care units?].
21 patients have been monitored after open heart surgery. Clinical and model analysis of the genesis of statistical interrelations between the cardiac index (CI) and left ventricular (Plv) and right ventricular (Prv) filling pressure has been performed. It has been shown that CI dependence on Prv or Plv is characteristic of the cardiac performance only in case CI variation is mainly associated with changes in the preload. CI variations are caused mostly by changes in the corresponding half of the heart, while CI dependence on Prv (Plv) does not characterize the heart function and is not Frank-Starling's curve, with the value and angle of the regression slope failing to reflect the degree of the heart pump function damage. It is concluded that in most cases it is practically impossible to assess the cardiac function by the shape of Frank-Starling's curves in intensive care wards.
