title: [Direct revascularization of the myocardium and left ventricular diastolic function in patients with ischemic heart diseases].
abstract: Echocardiography (echo-CG) and stress-doppler echo-CG were performed in 78 patients with ischemic heart disease (IHD) before and 1 to 8 years after the operation of direct myocardial revascularization (DMR). Polyposition coronarography with shuntography was used as a reference method. After DMR, stress-doppler echo-CG showed in capable shunts (vs resting values) that in insignificant reduction of early filling maximal rate (73.6 +/- 4.2 cm/s and 68.8 +/- 3.1 cm/s, respectively) the rate of late filling lowered significantly (64.7 +/- 4.5 cm/s and 58.1 +/- 3.9 cm/s, respectively), time of early filling inhibition (0.24 +/- 0.02 s and 0.18 +/- 0.04 s, respectively) and time of isovolumic relaxation (104.2 +/- 1.5 ms and 100.1 +/- 1.2 ms, respectively). An opposite picture was observed in patients with occlusive shunts. Thus, improvement of left ventricular diastolic function in IHD patients after aortocoronary bypass operation occurred only in capable shunts. Time course changes in the readings of stress-doppler-echoCG can indirectly characterize shunt function after DMR.
