Introduction: The work addresses the targeted intervention of cardiovascular diseases at medical staff. SET AND METHODICS: During 2002-2004 years, within the scope of preventive examination, there was made targeted prevention of risk factors of cardiovascular diseases (CVD) at the big hospital employees at the Centre of preventive care of employees and in the department of preventive cardiology of Ist Internal Clinic of LF UP and FN Olomouc. According to the effective tables, there was stated a CVD risk of these employees. The employees received a personal individual letter which informed them of the level of CVD risk and proposed a targeted intervention of risk factors. The part of the set--427 employees of the average age of 38.93 years (SD 11.39), 69 men (M) of the average age of 40 years (SD 12.47) and 358 women (F) of the average age of 38.7 years (SD 11.18) was examined another time during 2004-2005 years. The methodics of second examination was the same as at the first examination, only the questionnaire was complemented by the questions related to the knowledge of the CVD risk stated at previous examination.
Results: There occurred statistically significant decrease of LDL cholesterol in the set (from 2.87 mmol/l to 1.23 mmol/l, p < 0.0001) and BMI decrease (from 24.35 to 24.16, p < 0.05) and at the same time statistically significant increase of total cholesterol (from 5.09 mmol/l to 5.27 mmol/l, p < 0.05) and triglycerides (from 1.27 mmol/l to 3.01 mmol/l, p < 0.0001). There was no significant change in other RFs (BP, WHR, HDL cholesterol, moving activity). The influence on RF of smoking was statistically significant (23 employees quitted smoking, 10 employees started, p < 0.05). 53 F (14.80%) and 3 M (4.34%) know their cardiovascular risk, 235 F (65.64%) and 53 M (76.81%) do not know their cardiovascular risk.
Conclusion: The work approved the influence of targeted intervention on the incidence of cardiovascular diseases risk factors and at the same time low level of knowledge of one's own individual risk, despite of targeted intervention.
