Аннотация Analysis of transmitral flow criteria has been used to underestimate diastolic dysfunction degree. The study goal was to compare the evaluation of different echocardiographic methods to determine diastolic dysfunction types. There were 120 patients with chronic cardiac insufficiency under the study; control group included 30 healthy individuals. Pulmonary venous flow, transmitral flow at rest in carrying out Valsalva test and tests with isometric exercise have been examined for verification of diastolic dysfunction type by Impulse Doppler Echocardiographic Method. The findings have been compared with the results of Tissue Doppler Echocardiography. Among patients with diastolic dysfunction type I according to the transmitral flow examination there were 22 (34%) with diastolic dysfunction type II using Tissue Doppler Echocardiographic method. Besides, 6 persons with diastolic dysfunction type III demonstrated no diastolic dysfunction signs according to the transmitral flow data. The Valsalva test enabled differentiation of diastolic dysfunction type II in only 39% of all cases while test standardization increased the method’s value up to 55%. The isometric exercise test for diastolic reserve indication may be compared by its effectiveness with Tissue Doppler Echocardiographic method used for detection the diastolic dysfunction restrictive types.
