[Subclinical disorders of left ventricular function in diabetics detected by echocardiography].

In diabetic patients, without coronary heart disease and hypertension, left ventricular filing dysfunction exist, that is registered by echocardiography. It is manifested as greater peak flow velocity during atrial systole and as shorter time from the aortic second heart sound to the peak of the early diastolic flow velocity curve. The diastolic dysfunction indicates increased left ventricular stiffness and may be the first maker of diabetic cardiomyopathy.
