Low-frequency magnetic fields and EHF-therapy have been used in correction of autonomic homeostasis in workers exposed to vibration for different periods of time. The workers suffered from early arterial hypertension. Vegetative status and central hemodynamics improved best in workers exposed to vibration for less than 5 years. If the exposure was 6-15 years, a positive trend occurred in the tension of regulatory mechanisms. Workers with long exposure to vibration suffering from vagotonia showed an inadequate response of the autonomic parameters to treatment. This necessitates enhancement of therapeutic measures with medicines.

The authors present results concerning use of low-frequency magnetic fields and HF-therapy for correction of vegetative homeostasis in workers with variable length of service, exposed to vibration, having early forms of arterial hypertension. The most positive changes of vegetative status and central hemodynamics are seen in workers with low length of service.

Whether the primary arterial hypertension prevention programme can be applied among employees of a Novosibirsk industrial enterprise within the framework of the second stage of the USSR Cooperative Study of Arterial Hypertension Control, is studied. For this, the authors used sodium-restricted diet concurrent with non-drug therapy (physio-, balneo-, reflexotherapy and acupuncture), and active sanitary education. The 2-year prospective follow-up showed a sufficiently high efficiency of health measures: the incidence of borderline hypertension was reduced by 10.5% at the end of the study, blood pressures could be maintained at the level of the borderline and subnormal values in most patients with persistent hypertension, the patients at risk developed no persistent hypertension, cases. In a 20% blind sample from the matched population, the changes in the frequency of various blood pressures were insignificant during this period.
