The author discusses possibilities of non-invasive assessment of left ventricular diastolic function in patients with ischaemic heart disease, using Doppler echocardiography with visualization of left ventricular diastolic filling. Attention is drawn to the fact that left ventricular filling is a very complicated process which depends not only on the diastolic function of the left ventricle but also on the given haemodynamic state of the patient and on other factors; this must be taken into account when interpreting Doppler filling curves. The author concludes that during gradual development of left ventricular dysfunction non-linear changes occur of the filling flow parameters of the left ventricle and therefore they are not suited for quantitative assessment of diastolic dysfunction of the left ventricle. The value of Doppler echocardiography for evaluation of the diastolic function of the left ventricle may be above all assessment of early disorders and the non-invasive estimate of high left ventricular filling pressures.
作者探讨了使用多普勒超声心动图观察左心室舒张期充盈情况,对缺血性心脏病患者左心室舒张功能进行无创评估的可能性。文中指出,左心室充盈是一个非常复杂的过程,它不仅取决于左心室的舒张功能,还取决于患者特定的血流动力学状态及其他因素;在解读多普勒充盈曲线时必须考虑到这一点。作者得出结论,在左心室功能障碍逐渐发展的过程中,左心室充盈血流参数会发生非线性变化,因此它们不适用于对左心室舒张功能障碍进行定量评估。多普勒超声心动图在评估左心室舒张功能方面的价值首先可能在于对早期病变的评估以及对左心室高充盈压的无创估计。
