[Effects of moderate alcohol consumption on the cardiovascular system of male operators].

It was established that among male workers of an energy enterprise there were 53.7% of moderate consumers of alcohol, absolute and relative abstainers--respectively 5.4% and 26.4%, regular consumers--14.7%. Alcohol addicts were not revealed. At rest, the pulse arterial pressure (PAP) in operators--moderate consumers of alcohol was by 10.9% lower (P less than 0.005) and was by 16.3% higher (P less than 0.005) than those in the sample group. The heart rate indices were tending to increase both in standing and sitting positions. The diastolic (DAP) and systolic (SAP) arterial pressure levels did not significantly change. In response to a moderate physical load the SAP and PAP indices in alcohol consumers vividly increased as compared with those in the sample group--respectively by 7.2% (P less than 0.005) and 41.4% (P less than 0.005).
