Modelling > Pathologies and modelling modes > Pathologies and parametrical modes > Diastolic left ventricular dysfunction

This pathologic mode is characterized by the following list of hemodynamic changes:

• reduction of stroke volume due to decrease of left ventricular inotropic status, that (in contrast to systolic dysfunction) is not accompanied by increase of end-systolic ventricular volume;
• increase of end-diastolic ventricular pressure, i. e. ventricular filling pressure;
• reduction of end-diastolic ventricular volume (myocardial hypertrophy) due to increase of left ventricular wall elasticity and reduction of its stressless volume;
• venous pulmonary passive congestion down to development of pulmonary edema, it is modelled by increase of total blood volume.

Diastolic ventricular dysfunction

a) norm; b) diastolic ventricular dysfunction: reduction of end-systolic ventricular volume, reduction of end-diastolic ventricular volume, reduction of ventricular stressless volume.
