[Comparative features of the tissue as well as traditional Doppler echocardiography in the diagnosis of left ventricular diastolic dysfunction in patients with chronic functional class I - IV heart failure].
Although Doppler echocardiography methods (DM) of lung veins transmitral and blood flows analysis traditionally used in a left ventricular (LV) diastolic dysfunctions (DD) non-invasive diagnostics are positive they also have their considerable shortcomings. A Tissue Doppler echocardiography method (TDM) has its advantage as it is independent of haemodynamic heart function in an analysis of CHF patients.


OBJECTIVE
To study capabilities of the both methods (DM and TDM) in an analysis of CHF patients diastolic left ventricular dysfunctions. To determinate sensitivity, specificity and reproductivity of TDM.


METHODS
80 CHF I-IV NYHA classes patients and 20 healthy volunteers (a control group) are studied. The patients were divided into 3 groups depending on their transmitral flow specters: first with LV relaxation dysfunction (n=24), second with pseudonormal type (n=33), third with restrictive type (n=23). In the general group a LV DD comparative analysis on DM and TDM results is done. In the second group these methods were compared as giving diagnostically DD data. For far finer TDM results in the group of 30 patients the data were compared with radionuclear vetriculography.


RESULTS
The usage of two TDM diagnostic criteria gives more CHF patients than DD method (81.1% to 75.8%). TDM sensitivity in left ventricular DD is up to 70%, specificity--over 90%, reproductivity--73-87%.
