[Left ventricular diastolic function in patients with type-I diabetes mellitus (based on pulsed Doppler echocardiographic data)].
Diastolic function was studied of left ventricle by pulse Doppler echocardiography in 42 patients with type I diabetes mellitus (DM) and 46 essentially healthy individuals. In DM patients diastolic function was manifested by rise in peak velocity of atrial filling, decrease in ratio of peak velocity of early filling to that of late one, increase in left ventricular end-diastolic pressure. The findings available suggest the atrial phase has an important part in the structure of diastole in DM patients because of a combined influence of tachycardia and increased rigidity of left ventricular myocardium. Values for early filling in the patients did not differ from those in controls. A conclusion is drawn to the effect that in DM patients tachycardia and hypercatecholaminemia may partly mask disturbances in relaxation.
