[Indicators of central hemodynamics in patients with arteriosclerosis obliterans of the aorta and arteries of the lower extremities].

Sixty six patients with atherosclerosis obliterans of the lower limb arteries were found to have severe central hemodynamic disturbances that correlated with the site of impairment. Central hemodynamic changes appeared as increased cardiac output and stroke volume, shortened tension period and prolonged ejection period. Cardiac derangement occurred under unfavorable hemodynamic conditions, which was followed by its hypertension and dilatation. Instrumental signs of preclinical heart failure were revealed in patients with multisegmental lesions, which should be regarded as a risk factor in performing reconstructive plastic operations.
