title: [Characteristics of Left Ventricular Diastolic Function in Patients before and after Coronary Artery Bypass Grafting].
abstract: Diastolic heart dysfunction occurs essentially in patients who suffer from chronic heart failure. In this context an investigation and application of different methods for diastolic function improvement remain a priority in the therapy of cardiovascular diseases.
  
  
  OBJECTIVE
  Our ain was to estimate coronary artery bypass grafting effect on the left ventricularfunctionality in patients with coronaty heart disease.
  
  
  METHODS
  Patients (30 men without myocardial infarction and 44 - with myocardial infarction) were investigated by Doppler Echocardiography before and after coronary artery bypass grafting for left ventricular diastolic function assessment. In addition, during the year after operation examinations were carried out. Analysis of the data allowed detecting two types of disorders of transmitral flow: rigid and pseudononnal.
  
  
  RESULTS
  Our investigation showed that transinitral parameters improved in patients after operation. Patients without myocardial infarction in anamnesis had a myocardium cell relaxation improvement (IVRT decreasing; p =0,046), but an active myocardium relaxation turned for the better (increasing of E/A (p <0,001) by component A lowering (p =0, 003). Changes of pulmonary veins parameters were followed by the improvement of left heart ventricle relaxation: active - PVD decreasing, p =0,051; and passive - PVA decreasing, p =0,028. Patients with myocardial infarction in anamnesis had an IVRT decreasing (p =0,040) and A decreasing (p =0,041). In addition, in this group left atrial function improved (PVS decreasing; p =0,037).
  
  
  CONCLUSIONS
  Coronary artery bypass grafting is effective in left ventricular diastolic function improvement and Doppler Echocardiography method can become an important criterion to estimate the treatment adequacy.
