[The effect of local vibration on central and cerebral hemodynamics]

Effects of vibronoise industrial factor on central and peripheral hemodynamics were studied as was the possibility of correction of changes by antagonists in short-action calcium channels. It is shown that 68.9% of those workers under chronic exposure to industrial vibration and noise have hyperkinetic-type blood circulation, 21.3% eukinetic, 9.8% hypokinetic type. Besides, workers exhibit diminution in general cerebral bloodflow presenting with spastic states of great and small arterial vessels. There is noted a length of service-related increase in percentage of persons presenting with eu- and hypokinetic types of circulation and advancing diminution in general cerebral bloodflow with progression of spasm of arterial vessels being recordable. Antagonists of short-action calcium channels have a beneficial effect on central and cerebral hemodynamics.
