The diastolic function and the correlation between pump and diastolic function of left ventricle were studied in 35 patients with idiopathic hypertrophic cardiomyopathy with subaortic stenosis via a M-echocardiographic investigation by Echoview 80 C in the routine method. The following indices were used: A. For the diastolic function: 1. Telediastolic dimension (TDD) and volume (TDV) of left ventricular cavity. 2. Dimension (DPhFF) and volume (VPhFF) of the left ventricular cavity at the end of the phase of fast filling; 3. Velocity of fast filling of the left ventricle (ml/sec) - (formula; see text) 4. Fraction of fast filling of left ventricle (%) - (formula; see text) 5. Velocity of backward motion of the anterior mitral cusp at the beginning of diastole (E - F segment); 6. Velocity of early diastolic motion of the posterior wall of left ventricle (PWLV); 7. Ratio between early diastolic (D) and systolic (S) interval of PWLV: D/S; 8. Telediastolic interval (A - C) of mitral valve; 9. Index of fast emptying of left ventricle; 10. Amplitude E - E' of mitral echogram; II. Area (cm2) between two mitral cusps in diastole. B. For the systolic (pump) function: 1. Stroke and minute volume (SV, MV) of left ventricle according to the cubic formula and Teicholz formula; 2. Telesystolic dimension (TSD) and volume (TSV) of left ventricular cavity; 3. Fraction of shortening (FS) of left ventricle (%); 4. Mean velocity of shortening of the circumferential fibres (mVcf) of left ventricle (circumf./S); 5. Ejection fraction (EF) of left ventricle (%). 6. Distance between left ventricular endocardium of interventricular septum and point E of mitral valve; 7. Fraction of systolic thickening of IVS and PWLV; 8. Velocity of systolic thickening of IVS and PWLV; 9. Amplitude of systolic motion of IVS and PWLV.(ABSTRACT TRUNCATED AT 250 WORDS)
