[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.
