[Effects of hostility on the risk of arterial hypertension, myocardial infarction, stroke in a sample of males aged 25-64 years (epidemiological trial on the base of WHO program MONICA)].

Aim: To study effects of hostility on the risk of arterial hypertension (AH), myocardial infarction (MI) and stroke in males aged 25-64 years.
Materials and Methods: A screening study of the population was performed in 1994 according to WHO program MONICA-psychosocial. The response in a random representative sample of 25-64-year-old males (n = 657) living in Novosibirsk was 82.1%. New cases of MI, AH and stroke were registered in the control periods 1994-2000, 1994-2002. Computer program package SPSS-10 was used for statistic processing. Cox regression model of the relative risk (RR) was employed.
Results: Hostility was rather prevalent among the examinees (76.9%). MI risk for 8 years was 4.65 times higher in hostile men. Hostility was not associated with higher risk of AH and stroke. Hostility was seen more frequently in men with poor education, workers and retired persons. These groups are also at the highest risk of MI.
Conclusion: Hostility raises MI risk in unstable society but had no effect on the risk of AH and stroke.
